COMPOSITIONS IMMUNQMODULADQRAS OF THE BILIS FOR THE TREATMENT OF DISTURBANCES OF THE IMMUNE SYSTEM
FIELD OF THE INVENTION
The present invention relates to compositions of the invention, compositions comprising Leas comprising
J them themselves, and to the use of said compositions in stage J B of mammals. In particular, the compositions are directed
WHEN they are dealing with diseases associated with disorders of the immune system.
t 9 BACKGROUND OF THE INVENTION
Therapies for the prophylaxis and treatment of cancer and inflammatory, infectious, and infectious diseases are continually being developed, all of which can be a direct result of an inadequate response to the immune system. Some of these therapies try to use the
i inrnu e releu cainent theme "A proposal is based on the specific elements of the immune system, mainly antibodies and T cells. For example, the invention has focused on the development of vaccines against foreign agents, or against certain
endogenous chemical messengers, talee as interleukins, to control or induce certain antibody reactions. A "Sß" second proposal is based on the isolation, cloning, expression and production of peptides and proteins at rtir of the pa -i is specific not antigonos of the immune system. For example, proteins, such as cytokines, which comprise
micelles produced by white cells, and interleukins, which stimulate lymphocytes and sweeping cells that digest foreign antigens, offer possibilities for therapies. ^^ Treatment of cancer, for example, can be "greatly * improved if the early immune response to a tumor can increase so that the tumor does not reach a critical size." Strategies that have been suggested to increase the response Immune to a tumor include: specific vaccines for antigens associated with tumor, the use of antibodies
"monoclonal against antigens on the surface of tumor cells, such as against the IL-2 receptor;
| ^ bioespeci fi c molecules that contain nti tumor and super antigen antibodies. Relatively recently, the role of the physiologically active polypeptide, known as tumor necrosis factor (TNF), has been studied. In particular, it has been shown that TNF induces tumor necrosis, without effects on the normal tissues of the living body. The amino acid sequence of the TNF, as well as the base sequence of the DNA encoding FNT, have been described in the U.S. Patent. No. 4,879,226. Because TNF has been shown to play a role in the induction of tumor necrosis, any agent that can stimulate the production or bioavailability of TNF in vivo has potential utility, as a treatment for several turnoral conditions. In addition, any agent that can stimulate human rhonocytes and macrophages to produce FNT ii'i v tro, is useful as a means to provide a source of TNF for therapeutic administration, as well as for analytical and diagnostic purposes. Other diseases also have or involve a response to the impaired immune system. For example, autoimmune diseases are disturbances where the immune system produces an antibody against substances that are not foreign to the body, resulting in inflammation and consequent tissue damage. For example, arthritis reuinatoi e (Rñ) is an autoimmune disease in which the immune system of the body mistakenly recognizes the normal cells of the lining of the joints, called synovium, as strange. The autoimmune attack can destroy the lining completely. In the most severe cases, the joints stop working and are surgically replaced with artificial joints. The FNT is a mediator of damage in RA. The progress from mild to severe symptoms can be very rapid. However, no treatment is available for patients with RA. Other essentially untreatable autoimmune diseases include eriternatosus lupus, multiple sclerosis, and amyotrophic lateral sclerosis.
Infectious diseases, such as those caused by bacteria, viruses, and other opportunistic pathogens, can only be successfully prevented or by fighting the immune system of the body. The immune system assembles or attracts one or both non-specific immune responses and factors to the specific immune response to combat said pathogens. Non-specific immune responses focus on cytokine production, primarily by inaccurate phage, and serve as a prelude to specific antibody responses. Inflammatory cytokines include TNF-a and are involved in an acute response directed to the sites of damage or infection, which is manifested by an increased blood supply. Pathogenic bacteria or viruses are submerged by neutrophils and acrophages in an attempt to * contain the infection in a small tissue space. Therefore, macrophages play an important role in the defense against infectious diseases as follows: (1) process and present the antigens to the lymphocytes so that immune responses mediated by antibody and mediated by cell can occur, - (2) secrete central cytokines to the immune response; and (3) destroying the antibody-coated bacteria, tumor cells or host cells. Macrophages can ingest and kill a variety -? a, "pu, 1. .at óno, _" co-o ba ana. , n, oS and pro * - »* ™, (pair sites). This capacity increases when the "phacophages" are "activated". The products secreted from activated macrophages are as diverse as those from any other immune cell.
These regulate both pro- and anti-inflammatory effects and regulate other cell types, these products include TNF-cx, IL-lß, IL-5, hydrolytic enzymes, and oxidative metabolism products. Bacteria that are eliminated primarily by this cell-mediated immune procedure include tuberculosis and other bacterial-bacterial infections, such as atypical bacterial infections seen in up to 50% of patients with AIDS, and anthrax, a potential bacteriological agent. . Fungal infections are common problems in first-line patients, such as those afflicted with AIDS or organ transplant patients. Protozoa include such organisms as malaria. Inflammatory diseases include endometritis and inflammatory bowel disease, which is also mediated by immune procedures. Endo etriosis is a dark disease of unknown cause and histogenesis that affects the women who undergo it. The disease is characterized by the inappropriate implantation, growth and function of endornetrial cells. The endornetrial cells and fragments, which are normally discharged during the menstrual cycle, are transported through the fallopian tubes in the epithelial cavity where, in some women, they are implanted, prolific and develop into endorhetriotic lesions. . However, since it appears that endornetrial cells are present in the peritoneal cavity of all women who undergo surgery, it is not clear at present why endosteal riosis develops in some but not all women. Endometriosis can result in painful inflamed tissue, abnormal bleeding, extensive scarring, painful urination or defecation, and organ damage.
ITT reproduce a woman, still leading to infertility »
There is no known treatment for endornetriosis, of short pregnancy, that provides temporary relief or surgery to remove the source of endo-uterine cells, which also causes sterility. 15 Recently, numerous reports have suggested that endornetposis is associated with changes in the immune system. Previous reports indicate that inrnunosupresive rats are associated with an increase in endotrhythmias in rhesus monkeys. Since that time, alterations in the
Cell-mediated and mood-mediated immunity have been observed in humans with endornet riosis. During recent years, studies have focused on the role of macrophages in endorhetriosis. The underlying hypothesis for these studies was that the
erythematosus regulates the growth of the endornetrial cell and prevents the proliferation of p-endometrial cells in normal healthy women. In women with endornet posis, erroneously placed endometrial cells were implanted, giving rise to endornetposis. The development of endornetposis is then a stimulus for the production of auto-antibody against endorheic cells and cell-derived antigens. These autoantibodies, together with activated phage products, can then interfere with the fertility and reproductive functioning of affected women. The cumulative results from these studies have revealed the following pertinent facts. (1) the peptoneal elimination system (consisting mainly of macrophages) that is believed to be responsible for the destruction of endoinotional cells
ectopic within the peptoneal cavity can be harmful in women with endornetposis extension, - (2) the activity of peritoneal macrophage of ectuosa in women with extensive endorne posis is related, at least in part, to a fact mediated with prostaglandma . Of esl
way, the significant stimulation of the peptonea macrophages is of women with extensive endometriosis in response to macr? Activators. phages, such as gamma interferon and endotoxin, can be achieved only when a prostaglandin synthesis inhibitor is included in the activation culture; (3) Monocyte products circulating from patients with endometriosis can be directly involved in
* regulation of the growth of endorheic cells. In a single co-culture topic, improvement of autologous endoinetpal cell proliferation was observed with rhonocytes from the majority of patients with endornet riosis, while suppression of pro e ration was observed with rhonocytes from The majority of fertile control patients; and (4) the proliferation of endometrial cells from patients with endorheneposis can be modulated by the cytokines derived from ina-eróphago. The results obtained to date suggest that the proliferation response of patients with endometriosis with limited disease can be improved by methylleukin-l-β (IL-lß) and TNF-cf. In contrast, the proliferation response of the endornet not from a patient with extensive disease is suppressed by IL-1β and FNT-Of. Therefore, the results of these studies suggest that the function of monocytes and macrophages from 0 patients with endorhetriosis play a significant role in the pathophysiology of the disease. In addition, it seems that some of these macrophage functions are affected differently by the severity of the disease. In women with limited disease, macrophages appear to be activated in the peritoneal cavity, and perhaps, in the circulation and their endothelial cells, they seem to be able to respond to different growth factors derived from the macrophage. In contrast, extensive endometriosis is characterized by the suppression of macrophage activation within the peritoneal cavity due, in part, to the hypersegregation of inrnunoregulatory prostaglandins. Macrophage products also seem to regulate the proliferation of the endotrium in women with extensive endorne posis; However, the qualitative differences in the response of endorhetrium to different cytoqs suggest that the sequences of defective macrophage activation in these women may contribute to, perhaps, the control of the disease. Inflammatory bowel disease (IBD) is a general term for a group of chronic inflammatory disturbances of unknown etiology involving the tract
gastrointestinal. These disturbances include non-specific ulcerative colitis and Crohn's disease. The f that they can layer., *. disturbances (eg, arthritis, pericholangitis) may represent autoimmune phenomena and therapeutic agents used
to treat IBD, such as corticosteroids and azatrioprine, can exert their effects through immunosuppressive mechanisms. Patients with inflammatory bowel disease may have hormonal antibodies to colon cells, bacterial antigens such as Escherichia coli,
lipopolysaccharide, foreign proteins, such as cow's milk proteins. In general, the presence and title of these in
The antibodies do not correlate with the activity of the disease; however, it is likely that these antigens gain access to immunocornpetent cells secondary to epithelial damage. In addition, IBD has been described in association with 5 again aglobulinern as well as IgA deficiency. Associated abnormalities of cell-mediated immunity include cutaneous allergy, diminished response to various mitogenic stimuli, and reductions in the number of pelvic cells. Bile, which is secreted by the liver and stored in the bladder, has been investigated for several purposes, including the use of bile extracts to improve the bioavailability of drugs that is rapidly metabolized by normal liver function (see UO). 90/12583) and to inhibit
the promotion of leukocytosis in a mammal (see Hmoda et al., Chem. Pharm. Bull., 30, 4429-4434 (1982)). Nevertheless,
Bile has never been considered a source of therapeutically useful compositions with respect to neoplastic, inflammatory or infectious diseases. From
In an interesting manner, in accordance with British Patent No. 337,797, it was suggested to use the bladder, by itself, as a potential source of anti-cancer agents, but only after having removed the bile from the bladder, and having - completely flushed the bladder., 5% BRIEF DESCRIPTION OF THE INVENTION
It has now been discovered that bile is an important source of a composition that can activate cells of the immune subject, such as macrophages and rhonocytes, and is effective in treating various cancers, especially cancer-pancreatic and malignant cancers. In particular, it has been discovered that the composition of the present invention can stimulate the production of TNF both in vitro and in vivo from, for example, macrophages. This property can be useful in the treatment of infectious diseases. It has also been found that the immunomodulatory effect (especially the ability to regulate or suppress the production of TNF-) of the present invention can also be used in the treatment of other disturbances involved with the immune system, such as antoinnune diseases. and inflammatory diseases and disturbances. The composition of the bile of the present invention is also believed to be useful as an adjuvant additive for vaccines targeting childhood diseases, and as a protection against the rejection phenomenon involved in xenograft procedures, for example. The composition of the bile of the present invention is obtained by extracting the bile with a solvent soluble or water-soluble. The extract thus obtained can be further processed to remove inconvenient or unnecessary components thereof. * The product obtained by the bile extraction procedure described in detail below has been found to have TNF-stimulating activity (or TNF inhibitory activity depending on the source of species) and is believed to have anti-cancer activity, infections , autoinrnun disturbances, and inflammatory disturbances. In particular, it is believed that the bile extract of the present invention is especially active against cancer.
Obviously, all the composition thus obtained may not be necessary to obtain said activity. Therefore, it is possible to separate, fraction, or otherwise process the product thus obtained, and still retain the desired ability to
stimulate the production of TNF, for example, to act against disturbances of the immune system that contain various diseases. In addition, it is observed that it is possible to synthetically obtain a product with the same or similar capacity to stimulate the production of TNF and to act against them.
disturbances of the immune system. In this way, it is observed that the components of the product can be identified and analyzed in terms of their respective contributions for the desired characteristics of the stimulation and capacity of the TNF to act against the disturbances of the immune system, among other biological effects. Furthermore, it is further noted that said identification and analysis will be used to manufacture a synthetic W-form of the product. In one aspect, the present invention relates to a composition for use as an immunomodulator comprising components of small molecular weight of less than 3000 daltons, 5 and having one or more of the following properties, a) it can be extracted from bile of animal; t > ) is able to stimulate rnonocitos and rnacró phagos i n vi tro e jj alive; c) is able to modulate the production of the factor of

DETAILED DESCRIPTION OF THE INVENTION
The hypothesis against! What guides these studies is that the therapeutic efficacy of a powerful biological stimulator may depend on its ability to attract adequate modulation of the immune system, such as by activating rnacro phages and / or rnonocytes to produce certain cytokines or promoting activity to search and remove or destroy cells induced or caused by the disease, such as foreign cells or mistakenly placed. For example, the shift function in environments containing malignant disease would be a useful therapy to combat cancer. Such a function could be generated by the direct stimulation of immune cells resident in tumor microbiotics. Alternatively, this function can be generated by stimulating the circulating immune cells if those cells were then able to lodge in sites of malignant disease and function in that environment. Other diseases and conditions that have an important immune system aspect would be combated or improved by treatment with a suitable immunornodulatory agent. Said diseases or conditions include endornetriosis (which is a disease condition in which normal endothelial cells proliferate in suitable sites), vain infectious diseases, and others, as will be described in more detail below. As previously mentioned in the present, the
The present invention relates to a composition for use as an immunomodulator comprising components of small molecular weight of less than 3000 daltons, and having one or more of the following properties: f .. - P ^ ^ ra-r- * - ».» -,., < . a a,, b and b) is capable of stimulating rhonocytes and macrophages in vivo; c) is able to modulate the production of the necrosi s factor to the; d) contains no measurable level of IL-iw, 15 IL-lß. FNT, IL-5, IL-8, IL-4, 6M-CSF or FNT-t; e) has an anti-proliferative effect in a malignant cell line; f) does not show cytotoxicity to human peripheral blood mononuclear cells or lymphocytes; Y
g) is not an endotoxm. More particularly, investigations have shown that at least one of the compositions of the invention stimulates normal rnonocytes to perform cytotoxicity towards Chang's hepatoma cells, which
test is used to measure the activation of rnonocito and rnacrofago. The rhnocytes and / or macrophages of K-cancer patients (including cervical, ovarian, napz / oi do / throat, lung, and endornetrial carcinomas, Kaposi's sarcoma, and chronic iogenous leukemia) have also been shown to be stimulated by the composition to attack and destroy your own particular tumor cells. In addition, the macrophages of patients afflicted with endonetriosis have been shown to be activated by the composition as well (see example 2S). The composition of the invention can modulate the production of tumor necrosis factor (TNF). A preferred composition of the invention isolated from bovine bile promotes the release of TNF from human peripheral blood rnonucleus cells and the pre-monocyte cell line U-937 in what appears to be physiological quantities. Since TNF is known to initiate a cascade of inflammatory and anti-tumor cytokine effects, the preferred composition can exert its antineoplastic effect by stimulating human leukocytes to release TNF (and possibly other cytokines). Accordingly, the present invention can also improve lymphocyte and inacrofago cytotoxicity towards tumor cells. It has been found that the composition of the invention also inhibits the growth of cells of the mouse hybrid cell HYB-6-1 line. The inhibitory effect of the composition on mouse hibrandna cells suggests antiprozymatory activity. The effect of the composition on the P survival of human peripheral blood cells (PBMNs) and lymphocytes was also examined. It was found that the composition was non-cytotoxic for human PBMNs and Imfoeitos. As exemplified below, the composition of the present invention has, inter alia, the following characteristics: 1) The component or components responsible for the release of TNF from PBMNs eluted early from a column of RP-HPLC Gis-2) The composition causes the release of interleukin-lß (IL-lß), and the component responsible for the release of IL-lβ elutes early from RP-HPLC, suggesting that it is probably the same substance (s) (s) that releases FNT. 3) The composition also causes the release of low amounts of interleukin-2 (IL-2). 4) The composition causes the release of granulocyte macrophage colony that stimulates the factor (GM-CSF), - 5) The ratio of the release of TNF to GM-CSF is 0 about 2: 1. 6) It is likely that the same (r) molecule (s), that is, component (s), in the composition will be responsible for the release of FNT, IL-lß and GM-CSF. It is possible that the composition acts to stimulate the release of 5 different multiple cytokines, or alternatively, the composition seeks the production and release of a cytokine which in turn stimulates the production and release of other cytokines. 7) Physicochemical analysis of the composition, including the precipitates and supernatants thereof, by means of SOS gel electrophoresis and rnolecular sieve HPLC.
indicates that the main components are less than 25U0 daltons. 8) The additional uirnical physical separation by hydrophilic molecular sieve HPLC (polyhydroxyethyl) confirms the small molecular weight of the components in the composition. 9) Analysis of acid arnin before and after acid hydrolysis suggests the presence of peptide bonds, indicating the presence of peptides. As mentioned before, the composition of the invention can be prepared by mixing the bile of a
animal, preferably a bovine, with an equal volume of an alcohol to produce a bile / alcohol solution; (b) separating the soluble fraction from alcohol and isolating a solution substantially free of alcohol; (c) removing bile pigments from the solution to obtain a liquid
light yellow; (d) treating the light yellow liquid to remove substantially any residual alcohol; (e) extracting the light yellow liquid with ether and isolating the aqueous phase; and (f) removing residual ether from the aqueous phase. The composition is obtained from the bile of any
animal that produces bile. While the composition may possess a different activity towards a specific disease or
As SJ is obtained from bile in one species as opposed to another, a generally adequate source of bile becomes shark, bovine, ovine, caprine and porcine. In most cases, it is practical to get bile from animals well
slaughtered butchers, such as cattle, sheep, goats and swine, to be used in the preparation of the composition of the invention. The bile so collected must come directly from bladders and / or liver organs (as appropriate to the anatomy and physiology of the species) of the slaughtered animals and must be substantially clear, thus indicating that the preparation of bile is substantially free of pus or blood. In a preferred embodiment of the method, bile from bovine sources is used. Bovine bile is abundant and 15, in part, relatively large quantities of each animal can be extracted. However, cattle are often slaughtered and inspected under health-related regulations, so that animals provide a reliable source for preparing the composition of the invention. In addition, humans are less likely to have an allergic reaction to material of bovine origin. The bile is mixed with an equal volume of an alcohol to produce a bile / alcohol solution, which is 50% alcohol. The alcohol can be an aliphatic alcohol, preferably methane, ethane or propane, most preferably ethane. A solution that is substantially free of the WÉ 50% insoluble material of alcohol can be isolated by centrifugation. Preferably, the bile / alcohol mixture is centrifuged at 3000-5000 f-pm, most preferably 4200 rprn, for at least 2 hours, at about 15-25 ° C. The alcohol contained in the soluble bile / alcohol solution can then be removed by taking advantage of the different volatility of alcohol and water, using conventional methods, ie, heating the fraction to a suitable temperature, for example, 80- 85ßC, for an appropriate amount of time, for example, up to about 10 hours. The bile pigments can be removed from the solution to obtain a clear yellow liquid using activated charcoal, polyarnidic granules or iLtration. Preferably, an activated carbon treatment is used. 5 The procedure can be repeated so that the solution satisfies the standards of optical density and conductivity. The clear yellowish liquid was treated to remove substantially any residual alcohol, using conventional methods. Preferably, the clear yellowish liquid 0 is filtered using a filter having approximately a retention of 1.0-3.5 μm, most preferably a retention of 2.5 urn. Then, the clear yellowish liquid was extracted with ether and the aqueous phase was isolated. The ether used in this step is preferably dirnethyl ether, ethyl ether, n-propyl ether, isopropyl ether, or n-butyl ether, most preferably ethyl ether. The residual ether can be removed from the aqueous phase, for example by heating the solution to
55 ° C, preferably up to approx. 40 ° C during
approximately 5-15 hours, very preferably for approximately 10 hours. The composition can be used without further modification, simply packing it into bottles and sterilizing. S The composition can also be used in a concentrated form. 0 A preferred concentrated form is prepared as follows. Prior to step (e) described above, the clear yellowish liquid can optionally be concentrated to approximately one-eighth the volume of the bile / alcohol solution., for example by heating to a temperature of minus 5 of about 85 ° C, preferably to about 60 ° -70 ° C. After step (f), the aqueous phase can be concentrated in one tenth of the volume of the bile / ethanol solution, for example by heating to about 80-85 ° C. In a preferred method for preparing a composition of the invention, the collected bile is mixed with an equal volume of ethyl alcohol. The bile / alcohol mixture is then centrifuged at approximately 4200 rpm for at least 2 hours, at approximately 20 ± 2C >; C. The liquid supernatant is decanted and analyzed for ethanol content and pH. The bile pigments are then removed using activated ammonium carbon. The treated bile / ethanol solution is then monitored to determine its optical density (O.D.) and conductivity. The levels of D.O. or conductivity levels outside of acceptable speci fi cations require
that an additional treatment is given to the bile / ethanol solution to remove bile pigments, for example treatment with activated charcoal again to achieve a reading within specification limits.
w Jfe. After treatment with activated carbon, the solution is filtered through a filter having a retention of 2.5 μm, the alcohol is evaporated off by heating to below 85 ° C and the solution is concentrated to approximately one-eighth of the volume original of the bil is / ethanol solution. The concentrated solution is cooled to between about 20-25 ° C. Then, this solution is mixed with ethyl ether and the ether phase is discarded. Preferably, relatively small volumes of ether and strong stirring are used, such as 0.1 to 1 volume, preferably 0.2 to 0.5 volumes. This step can be repeated once. The aqueous phase is heated to remove residual ether by heating to 55 ° C for about 10 hours, and then reduced in volume to one tenth of the original volume of bile / ethanol heated to about 80-85 ° C. This solution is then analyzed to determine appearance, biological activity and ethanol and ether content. The pH of the composition can be adjusted to the pH -? physiological, osto is, 7.4-7.5, using a solution of hydrochloric acid (L%) and sodium hydroxide (1% solution), and a solution regulated in its pH can be obtained using dibasic and monobasic salts of sodium phosphate as regula pH meters,
using conventional methods. The composition can be used without further modification by simply packing it into bottles and sterilizing it.
A preferred method of sterilization is to subject the composition
? to three cycles of sterilization by autoclaving, followed by
Incubation ID The composition can be used in a concentrated form. The preparation of the concentrated form was described above. Also, the composition can be made freeze-dried. The composition and the concentrated composition are
clear yellow solutions essentially free of foreign material containing no more than 10 ppm of ethanol and no more than 5 ppm of ether. The compositions activate PBMNs to release FNT m vitro as measured by the rnonocito / macrophage activation test (TNF release) as described in Example 2. In addition, the compositions activate PBMN's, for example from a patient with cancer, which later mediated cytokine activity against cancer cells derived from the same patient. In fact, clinical studies involving animals and humans have shown efficacy against tumor treatments using the composition of the present invention. Similarly, it has been seen that PBMN's activated with the composition <
< They act on endotrial cells, such that the use of the composition to treat endoin and other inflammatory diseases is provided by the present invention. The compositions of the present invention can be produced in a consistently reproducible manner using the method described above in general form, with proven identity, potency and purity from batch to batch. Identity and purity are determined using chroma ografí reversible phase high pressure liquid (see example 1). the compositions of the invention have a consistently reproducible pattern on reverse phase HPLC. The HPLC readings for three batches of the concentrated composition of the invention are shown in Figures 1 to 3. The compositions also
are characterized by the above-mentioned properties, for example their ability to stimulate erythrocytes and erythrogens in vitro and in vivo, etc. Compounds that are probably present in this composition, considering the source, include acids
Sulfonated bile, oxidized bile acids, other bile acids of natural occurrence and their amino acid conjugates (especially glycine and taurine), and sterols. Therefore, it is believed that the present composition includes at least one compound having the formula
wherein the molecule may or may not be completely saturated, so that, for example, the molecule between A and B, B and C, or C and D H, OH, = 0, or
"n CONHR;
Wherein R is an amino acid residue such as for example glycyl, giutamyl or tauplo, thereby forming the conjugate of glycine, glutaryl or taurine. In particular, the composition of the present invention has been analyzed with respect to its component compounds, including organic and non-organic components.
This information was derived using normal methods of analytical chemistry, including loop spectroscopy (FM). The results of these studies include, for example, identifying specific compounds ICOS bLliar acid so estimated are present, including cholic acid, 5 glycocholic, deoxy glycocholic acid, ursodeoxycholic acid, cholesterol sulfate, deoxycholic acid, quenodesoxícól ico , and taurocolieo acid. From MS it is not distinguishable whether the loss of
J. OH and l-2 of some compounds occur in the CM or if the anoxic, deoxy, dideoxy and unsaturated analogs of these compounds are also present from the beginning.

EXAMPLE 1
This example describes and illustrates the preparation of the composition of the invention. Bovine bile was collected from the biliary vesicles removed from healthy cows (both males and females) that were at least one and a half years old. These cows were sacrificed for use as food in an approved and inspected abattoir. The sacrificed animals had been inspected and evaluated as healthy prior to slaughter, and the biliary vesicles were separated from the livers and examined by a veterinarian to confirm that the biliary vesicles were free of parasites and evidence of infection, and were thus appropriate for used as a source of bile for the present invention. The biliary vesicles that passed this inspection were subjected to the following procedure: The biliary vesicles were wiped with a 70% ethanol solution to clean the exterior of the vesicles, and the
bile was removed from the vesicles with a syringe. The removed bile was examined visually in the syringe by the veterinarian to make sure it did not contain blood or pus and was satisfactory. The bile of a healthy bovine is a greenish fluid substantially free of blood and pus. They were collected
also fragments of livers, spleen and lymph nodes of the animals whose bile was collected, and the fragments were examined
'st for the presence of parasites and other indications of disease. For species that do not have a defined gallbladder (such as the shark), bile is obtained directly from the liver organ. The bile that was found was satisfactory, transferred in a graduated amber flask containing ethanol to give a solution of 50% bile / 50% ethanol by volume. The
The bile / ethanol solution was a greenish fluid substantially free of foreign material and tested as positive for ethanol.

(Advanced Magnetics, Inc.); IL-6 (Advanced Magnetics, Tnc); IL-1 (Advanced Magnetics, Inc.); IL-4 (R &D Systems); e TL-8 (RSD ¡j-y Systems), The results indicated that FNT was the main cytokine present in the supernatants, along with smaller amounts of IL-1β and GM-CSF. For example, a dose of 40 μl of the composition of example 1 (lot B0222) stimulated the production and release of 178 pg / ml of TNF-a, 136 pg / ml of GM-CSF and 142 pg / ml of IL-1β . 5 Different batches of the composition of Example 1 were examined for their effect on the release of TNF induced by LPS. In summary, it was found that batches of the composition produced in the same manner and from the same animal induced an identical effect. However, the 0 variations in the method of preparing the composition or the use of a composition prepared from different animal species had different effects. For example, lots B29 / 3006, B0213, BC0241, BC0241-01, BC0242 (B = bovine) and C0203 (goat) induced a marked release of TNF at the top 5 of that induced by LPS alone, as shown in Table III , while lot 013/2109 (sheep) minimally stimulated the release of TNF in all doses tested. In
• contrast, the. Lot R0201 (shark) inhibited the release of TNF in most of the doses tested. The TNF values shown in Table III were calculated as the difference in the release of. FNT-a between the stimulation produced by LPS and the composition of example 1 combined, minus the stimulation produced by the LPS alone.

Since the composition of Example 1 affected the release of. FNT induced by LPS from human PBMNs, a series of experiments was performed to examine the effect of the composition on the release of TNF induced by LPS from PBMNs with time.

Table IV shows that, during 2 hours, level 30 of TNF release from PBMNs induced by LPS had risen to 697 pg / ml and reached a maximum at 6 hours at approximately 2006 pg / ml. During 24, 48 and 72 hours, the release of TNF progressively decreased. In fact, during 48 and 72 hours, the release of TNF from PBMNs induced by LPS was just above the constitutive levels of production. In contrast, the LPS in combination with lot 52
* B0213 of the composition, which is a strong simulator of the release of TNF, induced a maximum release of TNF in 24 hours, at a time when the stimulating effect of LPS had begun to decrease. Unlike the LPS alone, the L.PS in
combination with batch B0213 of the composition with inuo stimulating the release of TNF for 48 and 72 hours at levels well above the constitutive levels of production. These data show that batch B02L3 of the jj composition of Example 1 is effective to stimulate
production of TNF over time. Lot R0201 of the composition, which was obtained from sharks and is an inhibitor of TNF release, markedly inhibited the release of TNF in 2, 6 and 24 hours.
For 48 and 72 hours, lot R0201 had positive effects or
minimum negatives ,. In summary, the above results indicate that some batches of the composition (eg, from shark) inhibit the release of TNF from PBMNs induced by LPS, while other batches, such as those
derived from cattle, goat and sheep, stimulate the release of TNF induced by LPS. In conclusion, the composition of the invention can modulate the production of the
FNT, both positively and negatively. A summary of the data is shown in Figure 5 and Table V. 25 TABLE V

The PBMN TNF test was described
Previously, it was normalized using 100 μl of the composition of example 1 and 50 ng of LPS. PBMNs from 3 different human subjects were obtained as described above, and were used on the same day. The results of each of the three tests (using individual cells of the subject) are
averaged to compensate for variations in response between different subjects. The analysis included determining the amount of TNF-α released in RPMI media alone and in the presence of 50 ng of LPS. The release of TNF-α was also determined in the presence of 100 μl of the composition of Example 1 in
combination with 50 ng of LPS. The TNF-α released in the media was subtracted from the LPS value to obtain the TNF-α released in the presence of LPS alone. The values of the media and the LPS were subtracted from the combined composition and the value of the LPS to obtain the TNF-a released in the presence of the composition alone (reported in pg / rnl). Thus, the release test of 5 FNT was used to quantify the power of the bile extract. It was also found that the composition stimulates the release of TNF-a from U937 cells, which originally derived from a patient with histocytic lymphoma, and shows

The particulate matter was pelleted by centrifugation at 350 x g for 10 minutes, and the resulting supernatants were stored at -20 ° C until they were tested for TNF-a. All Virulizma samples were tested on two separate occasions. 25 Two ELISAs from two sites were performed to quantitate TNF-a in the supernatants of the U937 cell culture using FNT-a ELISA kits purchased from Endogen, Inc.

Since several ether sulphates participate in the regulation of many cellular events, such as cell proliferation and cell differentiation, sample D was analyzed for sulfate ions before and after acid hydrolysis. Using whole sample D (ie, unfractionated), the non-hydrolysed sample gave sulfate at 1000 μM, while the hydrolysed sample gave sulfate at 122 μM. Since the concentration of sulfate ions increased after acid hydrolysis, these results suggest that 20% of the total 5 sulfate ions present are sulfate esters have identified standard physicochemical values for the composition of Example 1 and are essentially consistent with the first studies, which are described in example 4. These standard values indicate that a consistent product can be obtained repeatedly.

This example describes the biological activity of fractions of the composition of example 1. The biological activity of fractions of the composition of example 1 was investigated. The analytical results are consistent with the biological activity of the composition that it is making attributed to low molecular weight components (ie, less than 300 daltons). This was determined through an experiment in which the composition was passed through the reverse phase HPLC described in Example 3 and diluted fractions that were isolated and analyzed for potency by the PBMN-FNT test described in the example 2. Significant activity was only detected at the first elution peak (Fl), that is, 5.6 to 6.2 rnins. which is consistent with the molecular weight of less than 300 daltons. (See table XV).

Additional experiments were done in the following manner to show that the active components (TNF releasers) had molecular weights less than 3500 and less than 1000 daltons. Lot BC241 was fractionated by carrying out a Folch extraction according to Ta ari et al., Agr "Biol. Chern., 40 (10), 2057-2052 (1977). The aqueous layer was dried on a rotary evaporator to produce a light brown granular solid. A stock solution of this solid was prepared at a concentration of 5 mg / ml. A portion of the sourcing solution was charged to Centri / by Centrifuge Concentrators (Spectrurn Products, Houston, TX) having a molecular weight separation membrane of 3500 to 1000 daltons. The concentrators were rifled at approximately 1500 x g until a portion of the material had passed through the membrane. The solution that passed through the membrane was evaluated for power in the PBMN-FNT test. The results were presented in table XVI.

EXAMPLE 6
This example 'illustrates the effect of the composition of Example 1 on T and D lymphocytes in the culture. The growth of human lymphocytes was examined under carefully controlled conditions in the presence and absence of the composition of Example 1. Normal concentrations of lymphocytes were incubated in wells containing various concentrations of the composition. When human T and D lymphocytes were incubated with the composition in concentrations similar to those used clinically, there were no adverse effects as determined by the exclusion of trypan blue dyes. Accordingly, the composition of the invention was non-toxic for normal T and D lymphocytes in culture. The effect of the composition on the survival of human PBMN was also examined. The PBMN were incubated during
24 and 48 hours in plastic plates with several volumes of the composition and tissue culture medium. At the end of this period, the number of surviving cells was estimated by the exclusion of trypan blue dye.

The ability of the composition to stimulate
# lmfocitos was evaluated in the following three indicator systems: i) stimulation of DNA synthesis of lonfoci, 2) induction of cytotoxic function mediated by lymphocytes; and 3) induction of cytotoxic function mediated by rnonocitos / rnaerófagos. These tests were chosen for selection because they measure munoological functions that have been shown to be associated with different clinical parameters in patients with malignant disease. These indicators of immune function can also be modulated in cancer patients-treated with different biological response modifying agents, such as IFN or IL-2. The results of the initial selection procedures are presented below. 1. Stimulation of lymphocyte DNA synthesis: comparison with an optimal stimulant concentration of phytohernagl utinin (PHA):

The macrophages were then stimulated in vitro as medium alone, 50 ng LPS or 0 VIRULIZINTN. stimulation measurements were made with respect to TNF (by ELISA) and NO levels (by spectrophotometric test using the Greiss reagent) in duplicate experiments. The standard error of the mean between the duplicate experiments was less than 10%. As indicated in the. Table XIX, VIRULIZININ induced a slight increase in production of TNF-a. (60-232 pg / ml) compared to background levels (medium) (120 pg / rnl), but VIRULIZINTN compared to LPS (2225 pg / nl) was not a strong stimulant of TNF-a release by rnacró agos Nitric oxide production was zero.

The macrophages were then stimulated with 0 50 ng of LPS alone or LP with different dilutions of VIRULIZINTN as before, FNT was determined by ELISA. As shown in Table XX, LPS only induces approximately 2900 pg / ml of TNF-a release from mouse peritoneal macrophages in vitro compared to 262 pg / ml for the medium.

When LPS is combined with VIRULIZIN ™, there is approximately 800 pg / rnl increase in release of TNF-a at VIRULIZATION dilutions of 1: 5 to 1.10 and increased release to at least 1:40.

The in vitro synergy of VirulizinT * "i with LPS for
40 nitric oxide (NO) was performed in the same procedure as before, except that NO was determined in the supernatant of treated rnacr-ofagos. As it was done before, the test for MO is an ornometric spectrophotometer and uses a Greise reagent. As indicated in the previous table, LPS produces some release of NO (9 μM). VIRULIZINIM in synergy with LPS induces a marked increase in NO production (13-27 μM) at 1: 40 dilutions.
VTRULTZINTM by itself did not induce release of NO pelma ero phages. The in vitro synergy VIRUL1ZIN ™ with IFN-t for release of TNF-α was studied using the same peritoneal mouse macrophages derived from C57BL / 6 treated mice as before. The data were included in the previous table referring to "smergistic combinations" As shown, the peritoneal mouse macrophages show a baseline release of TNF-a after 24 hours of in vitro culture. The same acrophages stimulated with LPS or IFN-x release almost
3000 pg / rnl of TNF-a. When VIRULIZIN ™ and IFN-t are added together, the release of TNF-a decreases. In comparison, the combination of LPS and IFN-t has an additive effect on TNF-α release. The in vitro synergy VIRULIZINTM with IFN-t for release of TNF-a was studied using the same peritoneal mouse macrophages derived from C57BL / 6 treated mice as before. The data were included in the previous table referring to "synergistic combinations" - Co or shown, LPS and TFN-t alone each increased the production of NO (9 and 7 μM respectively). VIRULIZTNTM added to IFN-t induced an M marked increase in production of No (47-57 μM) that almost equaled the combination of L.PS and IFN-t (74 μM). The results are consistent with the conclusion that VIRULIZINTM in combination with IFN-t increases NO production but
inhibits the release of TNF-a The in vivo production of TNF-a for 72 hours was studied in macrophages harvested from C57BL / 6 of mice which, before being harvested, were not treated, were injected intraperitoneally 72 hours before with 1.5 and 4 % protease-0 peptone, or injected intraperitoneally between 72, 48 or 24 hours before with 1.0 ml of VIRULIZIN ™ diluted 1:10 in PBS. The macrophage RNAs were treated in vitro for 24 hours with IFN-t (50 μ / rnl), LPS only (5 ng / ml), or the combination thereof. FNT and NO were determined as indicated above. The data is presented in table XX.,

As described, the TNF-α release of rnacrophages was examined in the absence of stimulation or with IFN-t LPS, or LPS / INF-t after 24 hours in an in vitro culture. The peritoneal mouse macrophages were shown to have little FNT-a after VIRULIZINTM live stimulation. When the
40 harvested macrophages were exposed IFN-t at 24 and 48 hours before the test, showed a small increase in TNF-a production. In contrast, harvested macrophages stimulated with LPS at 24 and 48 hours, but not at 72 hours before the test, showed increased release of TNF-a. Likewise, there was a synergistic effect of LPS and IFN-i on harvested macrophages that were stimulated 24 and 48 hours but i 5 not 72 hours before the test. Will the production go live from NO for 7? hours was studied with acrophage cells and tests under the same conditions described above with respect to La

NOT measured at 24 and 48 hours after intrapeptoneal injection of VIRULIZINTM (hereinafter TP VIRULIZINTM). When the harvested cells were incubated with IFN-t, there was a marked release of NO, and the harvested inacrophages having IP VIRULIZIN ™ at 24 and 48 hours before
of the test showed an exponential increase in NO release, which fell beyond 72 hours towards the baseline IP values of IFN-t alone. When the harvested cells were stimulated with LPS, they showed a markedly increased NO response, which was once observed for 24 and 48
hours of macrophages treated with IP VIRULIZINiM compared to macrophages that had not received IP VIRULIZINT. "The harvested macrophages that had received IP VIRULTZINTM before did not respond differently to the macrophages that did not have a pre-treatment with VIRULIZTNTM.
when the harvested macrophages pretreated with VIRULIZTN ™ were incubated with LPS / IFNt, they showed an increased production of OM compared to the macrophages that were not previously treated. The maximum response was with macrophages pretreated with VIRULIZIN ™ 48 hours before being harvested and tested.
EXAMPLE 9
This example illustrates the activation of monocytes and I L macrophages with the composition of Example 1 and methods for
try the isma. Research has shown that the composition of Example 1 will activate normal monocytes to demonstrate cytotoxicity towards the Chang heptorne cell line, which is used to measure rhnocyte toxicity, and that
monocytes and macrophages of cancer patients (e.g., those affected with cancers of the cervix, ovaries, ear / nose / throat, and endometrium / uterus, and chronic ioganelle leukemia) have been stimulated by the composition to attack and destroy cells turnorals derived from the same patient. Very particularly, the turnuricity function of monocytes has been pro-a in the presence of the composition of the invention and the basic procedure for these experiments are outlined below. In this procedure it has been called the "cytotoxicity test of rhonocytes / rnacrophages for lines
of analogous cells and turnoral cells "or" cytotoxicity test "for brevity.
/
W The method requires the isolation of onocits / RNAs, which is achieved in the following way: venous blood is collected aseptically in Vacutainer heparini ados tubes. The sterile hepapne book of preservative is added to a final concentration of 20 units / ml. The blood is diluted 3: 1 in Hanks balanced salt solution (HBSS), stratified with lymphocyte separation medium and centrifuged to obtain a band of rnonuclear cells of
- L peripheral blood (PBMNs). After the centrifugation, the
The mononuclear cell layer is recovered from the adjoining surface, washed twice in the medium (the medium is 1640 medium of the Ros ell Memorial Memorial Institute CRPCMI supplemented with 10% fetal bovine serum inactivated with heat, 50 units / ml of penicillin and 50 μg / ml of streptomycin a) and the
monocytes are enumerated by ingestion of latex. The inonocytes are isolated by means of adhesion in 96-well plastic plates for 2 hours at 37 ° C, followed by 2 cycles of washing with the medium). It is estimated that the adherent cells are greater than 90% rnonocitos. The cavities that contain cells
adherents are incubated overnight in the presence of VIRULIZIN ™ (final dilution of 1: 10-1: 20), then the adherent cells are washed to remove VIRULIZIN ™ and incubated overnight with tumor cells. The tumor cells are maintained in the medium in which the concentration of
Endotoxin is guaranteed by the manufacturer that it is low and that it is not stimulating in the test.
For studies in which a normal cell line is used, Chang hepatoma cells marked with 5c
(chromium) because this cell line is insensitive to the cytotoxicity of natural killer cells. These hepatoma target tumor cells are added to the monolayers of adherent cells at effector cell ratios: target
(E: 0) from 20: 1 to 15: 1. This ratio of E: 0 is used because it falls within the plateau scale in one on a prepared curve by varying the ratio E; G from 5: 1 to 30: 1, After 24 hours, the supernatants are collected and the sicr release is quantified. The specific cytotoxicity in percent is calculated as follows:% specific release = E-S X 100 T-s in the above equation, E = CPM released from the target cells in the presence of effector cells; S = CPM released from target cells in the absence of effector cells; T-CPM released from target cells after treatment with dodecyl. 2% sodium sulfate). For studies using autologous tumor cells, these cells are obtained from siCr-labeled surgical biopsies, and are used in the same way as the hepatoma cells described above. The preparation of peritoneal and alviolar macrophages is done by the methods described in Braun et al., Cancer Research, 53, 3362-3365 (1993). Using this protocol, it was found that the composition W makes the rnonocitos of healthy donors exert totox icity towards the cell line of Chang's hepatoma. Subsequently, it was investigated whether the onocites or cancer of a cancer patient could be stimulated by the composition to attack and destroy their own particular tumor. Using similar protocols as described for the normal cell line (Chang hepatothane cells), peptoneal rhonocytes and / or peptoneal cancer patient macrophages were isolated. Peritoneal macrophages were isolated from peptoneaie fluids collected at the time of laparoscopy. It was found that the composition activates peripheral rhonocytes and peritoneal macrophages of a patient with cervical cancer to produce cytotoxicity against the patient's own turnoral cells- This effect was comparable with or better than that produced with the combination of IFN and LPS- The peritoneal rnacrophages A patient with ovarian cancer was also found to be stimulated by the composition to attack and destroy the ovarian turnoral cells in culture.
Studies on monocytes / maerophages with composition Because selection procedures showed that the composition does not stimulate the functions of lymphocytes but can stimulate monocyte functions, subsequent studies were directed to the characterization of rnonocyte stimulating activities. Metamorphoses of the VP composition. A number of comparative studies aimed at determining the dose-response characteristics of the composition in the stimulation of the tumoricidal function of rhonocytes / rnacrophores were thus carried out with the pruoba of 5 different batches of the compound. The main emphasis of the studies was given to the test of the capacity of the composition to stimulate the turnoricida function in monocytes and aerofages from different anatomical sites of patients with
9 cancer For these inventions, it was based on the following: (1)
peripheral blood rnonocitos of cancer patients and control subjects; (2) inaviolated alviolar phages of patients with cancer in the lung and control patients with non-malignant lung disease; and (3) peritoneal macrophages of patients with gynecological malignancies. 15 Dose response studies were completed with different batches of the composition all prepared according to example 1. These studies were based on peripheral blood rnonocytes to test the stimulatory activities of different doses and different batches of the composition ( Lots
nos. 216, 219 and 222). Each batch of the composition was tested with dilution (net), a dilution of 1:10 and a dilution of 1:50 of material. The results are illustrated graphically in figure 1. Batches # 222 and # 216 were shown to stimulate the function
turnoricide of monocytes, however, lot # 219 did not. Apparently lot # 222 was superior to lot # 216 in those preliminary investigations. Lot # 222 apparently stimulates the equivalent levels of the turnoricide function in undiluted sample (net) and dilutions of 1:10, but lower, activity still detectable at the 1:50 dilution. Lot # 216 gave the greatest stimulation of the turnoricidal function at the undiluted concentration (net), with less activity at the 1:10 dilution and without detectable activity at the 1:50 dilution. As indicated above, lot # 219 did not produce detectable rhonocyte turnoricity at any concentration tested. 0 The turnoricide function in peripheral blood rnonocytes was also evaluated. Four peripheral blood monocyte samples from control subjects were tested. These tests used an optimal stimulatory composition concentration (1:10 dilution of lot # 222) and an optimal stimulating concentration of IFN-t plus LPS. The target cells in these studies were a cell line insensitive to NK, cultured, that is, the Chang hepatorne. The results are presented in the following table.
0 Stimulant (E / T-20/1)% of "cito-toxicity Medium 5.4 ± 1 IFN-t + LPS 18.6 ± 4 5 Composition 22.3 ± 6
A test was also performed on a sample of rhnocytes from a patient with cervical cancer. This test was important because the patient's own tumor cells were available to be used as target cells in the test. As before, this test used an optimal stimulatory concentration of the composition (dilution of 1:10 of batch # 222) and an optimal stimulatory concentration of IFN-t plus LPS. Also, the effect / target cell ratio was reduced to 15/1 to preserve the patient's tumor cells. The results of this test are presented in the following table.
Stimulant (E / T-20/1) Cytotoxicity% * Medium 5.5 IFN-T • * LPS 14.4 15 Composition 20.9
In the peripheral blood rnonocitos of control subjects, the rhnocyte composition of the turnoral function stimulated against Chang Hepatoma cells at an equal level
or greater than the level produced by means of an optimal stimulating concentration of IFN-t + LPS. In peripheral blood monocytes of a patient with cervical cancer, the monocyte composition of turnoral function stimulated against the cancer cells of the same patient a
a level that exceeds that produced by means of IFN-t plus LPS by more than 30%. The turnoral function was tested in macrophages of the peritoneum of patients with gynecological malignancies. These tests were performed on macrophage samples from the
peritoneum isolated from washing fluids of a patient with ovarian cancer. These tests were carried out with patient's turnoral cells as target cells in this trial. As above, an optimum stimulating concentration of the composition (1:10 of Charge No. 222 dilution) and an optimal stimulating concentration of IFN-t was compared. more LPS. Also, the effector / target cell ratio was reduced to 15/1 to preserve the patient's tumor cells. The resulting information was:
Stimulant Cervical Cancer Ovarian Cancer Medium 8.2 0.6 IFN + LPS 29.8 4.1 Composition 13.2 8-9 15 The results of these tests highlighted the fact that the local tumor environment can be a determinant of the response of immune cells to the inunitological activators. In this case of cervical cancer, there was no pathological evidence of malignant disease within the peritoneal cavity and the development of turnoral function against the tumor derived from itself was better with combined IFN-t and LPS than with the composition. In the patient with ovarian cancer, there was a significant tumor in the peritoneal cavity. The response against
the patient's own tumor for combined IFN-t t LPS was minimal when more, so the response to the composition was higher. The turnoral function was tested in alveolar rnacrophages of patients with lung cancer and control subjects. These tests were performed on samples of alveolar rnacrofago isolated from bronchoalveol lavage fluids of a patient with malignant lung diseases. These tests used an optimum stimulant concentration of the composition (1:10 charge dilution No. 222) and a combined stimulant concentration of IFN-t and LPS. The target cells in these studies were Chang Hepatoma cells and the effector / target cell ratio was 20/1. The resulting data were: * 10 Stimulant Patients with Cancer Control Medium 2.6 ± 2 19.5 í 4 IFN -t + LPS 10.9 ± 13 1.2 ± 4 15 Composition 5.2 ± 2 18.6 ± 8
The results were consistent with the observation that the alveolar rnacrofagos of patients with lung cancer are nons in their development of turnoral function in response to conventional inacrophagous agents such as IFN-t + LPS. The results showed that the tumor function of the alveolar macrophages of patients with cancer in the lung is reduced more compared with control subjects. The data presented above indicated that VTRULIZINR is a poor stimulator of alveolar macrophages. Further investigation with alveolar rnacrophages of patients with non-small cell lung cancer is presented in Example 23. Activity in alveolar macrophages seems to vary with the VIRULIZINR preparation. Thus, the cytotoxicity of the alveolar macrophages was described in only 2/7 alveolar macrophage preparations with the proven source loads (222, 219, 216). In contrast, 3/4 alveolar preparations were stimulated with the last preparations (233, 238). The difference could be related to the age and power of the preparation or the variability of the patient. Therefore, the composition can activate the tumor activity in alveolar rnaerophagous. The preliminary m vitro tests with the composition showed that it is a rnacrofago activator. The provided material was able to deduce turnoral activity in a normal cytotoxicity assay against an NK-insensitive cell and against freshly dissociated human tumor cells. It was also found that the deduced activity is dependent concentration in these tests. The ability of the composition to activate the macrophage tumoral function vi tro was comparable with that of the best erofaga activator combination available today., essential in e, endotox a (ie, LPS) combined. As stated above, the ability of the composition to produce this level of tumor function in the absence of endotoxin could be considered biologically important if the material is free of endotoxin contamination. The composition is free from endotoxin contamination when tested for pyrogens by means of the United States Phylochemical Test 5 (USP). Corno has been found for other LOO activators
f? _ftl macrophages, the activity of the composition is the tumor function stimulant of inacr phagos varies with the source of macrophages. It appears that the compositions are an excellent activator of peripheral blood rhonocytes being equivalent to IFN-t 5 + LPS with normal donors and possibly higher than TFN-t + LPS with patients suffering from cancer. Malignant disease has an important impact on the development of your oral monocyte function that depends on the activator used (Braun and
"k others, (1991).) One of the biological activity eradicating
different triglycerides in rnonocytes from cancer patients is the activator sensitivity for arachidonic acid metabolism and the secretion by the cell of prostaglandins. From these initial studies with the composition, it seems that the activity produced with the compound
is not sensitive to the inhibitory effects of protaglandins. If the insensitivity of protaglandins can be definitively tested for rnonocytes in cancer patients with the composition, it would be considered therapeutically important, because the
effectiveness of many other theological activators through protaglandins. Preliminary studies with 2 specimens indicate that the composition may have good activity in peritoneal macrophages, particularly when the malignant disease is present in the peritoneal cavity. 25 These preliminary results also illustrate that it has been found when comparing the ability of different pP activators to stimulate the turnoral function in peritoneal macrophages of patients with different gynecological malignancies. In these studies, it was found that the presence of malignant disease within the peritoneal cavity influences the ability of macrophages to respond to specific activators. In patients with cervical cancer, malignant disease is not present in the peritoneal cavity in general, and from this, the response of resident macrophages to IFN-t - * LPS is normal. However, when
The disease is present in the cavity, co or in the case with ovarian cancer, the response to TFN t + LPS is suppressed. This refers, in part, to changes in aci or arachidonic metabolism of peritoneal cancers when malignancy is present (Braun et al., 1993). The fact
that the composition activates the tumor function in macrophages of the peritoneum of patients with ovarian cancer against
The patient's own tumor cells are consistent with a mechanism for activation that is independent of the pathway of the arachidonic acid. Therefore, as shown in the aforementioned m vitro studies, the composition of the present invention is capable of activating rhonocytes and macrophages to increase the function of their immune system.
H EXAMPLE 10
This example illustrates the turnoral function in response to the composition of the invention and to other activators 5 macrophages in peripheral blood rhonocytes and macrophages of the peritoneum of patients with gynecological diseases. The patient population consisted of 7 patients, 3 with benign disease and 4 with malignant disease (2 ovarian pV cancers, 1 endo etrium cancer and 1 cervical cancer). The 10 samples were removed from the patients at the time of the surgical procedure. Preparations containing peripheral blood monocytes were isolated from the blood samples using the procedure set forth in Braun et al., Cancer Irnununol. Irn unother. , 32, 55-61 (1990) and the
preparations containing peritoneum macrophages were isolated as described in Braun et al, Cancer Research, 53, 3362 (1993). The cytotoxicity of the tumor cell was determined in response to the composition of the invention (1:10 dilution of charge supply No. 222) and other activators,
essentially IFN ~ t (100 U / rnl), IL-1? (500 U / ml) and CSN rnonocito (500 U / ml) using the rnonocito cytotoxicity assay described in Braun et al. The results as shown in the following table demonstrate that the composition of the invention stimulates
the turnoral function in the peripheral blood rnonocitos and in the macrophages of the peritoneum of patients with malignant and non-malignant gynecological diseases. The results are re-cited as percentage of tumor cytotoxicity (± S.E.) in an inocyte / tumor cell ratio of 15: 1.

Therefore, the tumor cytotoxicity produced by the composition of the invention is equal to or greater than that produced by the other biological stimulators that were tested.
EXAMPLE 11
This example 1 illustrates the effect of indomethacin, an inhibitor of prostaglandin synthesis, on the development of tumor function in response to the composition of the invention; The impact of other macrophage activators on peripheral blood monocytes from patients with 0 cancer was also investigated. Samples of patients with malignant disease in example 10 were tested using the assay system as described in example 10 with the exception that indoinetacin (up to 5 ng / ml) was added simultaneously with the composition of the invention, IL-12 (500 U / ml), and rnonocito -CSF (500 U / rnl). The results are shown in the following table indicated that indornetacin increases cytotoxicity in response to IFN-a, GM-CSF and M-CSF.

In this way, the development of tumor function in response to IFN-t, -GM-CSF and M-CSF was regulated by means of a function sensitive to indomethacin. In contrast, the development of tumor function in response to phorbol ester (PMA), IL-12 and the composition of the invention was not regulated by a function insensitive to indomethacin, ie, indornetacin does not increase cytotoxicity in response to the composition of the invention, IL-L2 and PMA,
EXAMPLE 12
This example illustrates the effect of the prostagland to E2 on the development of tumor function in response to the composition of the invention in the presence of indoinetacin. The subject population consisted of one normal and nine patients (one healthy, one patient with a pancreatic tumor, two patients with tumors in the head and neck, one with endornetposis, and four with HIV). The preparations containing peripheral blood rhonocytes were isolated from blood samples of the patients using the procedure described in Braun et al. (1990). The cytotoxicity of the turnoral cells in response to the composition of the invention (1:10 loading dilution No. 222) and mdometacin (up to 5 ng / ml), with or without PGE2 (IO ^ M), was achieved using the assay of rnonocito cytotoxicity described in Braun et al., 1 bid. The results are presented in the following table, in which the results are re-cited as percent cytotoxicity of tumor in a rnonocito / turnoral cell ratio of 15: 1.

The data in the following table shows that the pathophysiology levels of PGE2 (10M) failed to suppress the level of turnoral function that develops in response to the composition of the invention. This conclusion contrasts with the ability of PGE2 to suppress tumor function in monocytes stimulated with IFN-t (Braun et al. (1993).
EXAMPLE 13 This example illustrates the development of tumor function against tumor cells derived therefrom in monocytes stimulated with the composition of the invention. The preparations containing peripheral blood monocytes were isolated from blood samples of 7 patients (three ovarian cancers, one endometrial cancer, one cervical cancer and two ENT cancers) using the procedure described in Braun et al. (1990). The cytotoxicity of thyraceous cells in response to the composition of the invention (1:10 dilution of loading supply No. 222) and indoinetacma (up to 5 rng / rnl), with or without PGE (10-8M) was achieved using the rhnocyte cytotoxicity assay described in Braun et al. (1990), with the exception that patient's patient cells were used in place of Chang hepator cells. The tumor cells of the patient were treated with collagenase and DNase, the individual cell preparations were prepared, and the cells were labeled or described in Braun et al. (1990). The results shown in the following table demonstrated that the composition of the invention is capable of activating the patient's own rnonocytes to control the patient's tumor.

40 consistent with not being subject to the inhibitory effects of prostaglandins, which is one of the main forms of immunosuppression in patients. The experimental data also support the usefulness of the composition in the treatment of peptoneal, alveolar and gynecological malignancies.
EXAMPLE 14
This example illustrates the results of tests conducted to calculate the protein within the composition. The protein calculation of the composition was performed fef using the Pierce Micro BCA 0 protein determination technique (Srnith et al., Anal, Biochem., 150,76-85 (1985).) A sample of 10 μl of a the composition was created as 1 ml with distilled water, and five concentrations of bovine serum albumin (0.150 μg / ml) were created to be used as standards, 0.1 N NaOH was used as empty, a mixture was added to all 5 samples of BCA (2% sodium salt of bicinconic acid), 4% of copper sulfate and microreagent A (NaaC? 3, NaHCO3 in 0.2N NaOH) The sample mixtures were incubated for 1 hour at 60 ° C, cooled , and the resulting absorbance was read at 562 nrn using a spectrophotometer The amount of protein in the test sample was then compared to the normal curve and the appropriate calculations made The protein concentration of the composition was found to be lower and it was calculated to be 32 μg / rnl.
EXAMPLE 15
This example demonstrates, in summary, the following: (1) the composition has a TNF-a releasing activity and the TNF-a releasing activity does not refer to any contamination with endotoxin; (2) sizing of macrophages improves the ability of the composition to stimulate the release of TNF-a; (3) the hi-perrnolarity of the composition is not necessary for the TNF-a releasing activity. To test whether an endotoxin effect was associated with the aforementioned biological activity for the composition of Example 1, additional experiments were performed on the composition with polixin added to the reagents. Polixirnin inhibits the action of endotox on the
leukocytes. The following table and the subsequent notes return to cite the experiment performed on the composition and its results.

It was found that the composition continues to liberate TNF-a when it adjusts for oslopathy, even to the point of being hypo-osnolar.
EXAMPLE 16 This example illustrates toxicity studies as to the composition of the present invention. Preliminary toxicity studies were conducted on a variety of animal species, as shown in the table below. 5 All the animals (listed in the following table) were determined based on the daily clinical observation while receiving injections of the composition on days 14, 21 and 30 after the same. The heinatological data were collected every third day during the first 30 days and once a month after this. No adverse effects were seen in any of the 358 animals included in this study throughout the period in which the injections were administered or during the next period (one rnes for all species except for dogs that continued for 4 months).
Animal Canti ad Dosis
A second toxicity study was conducted to
To determine the effect of a large single intramuscular dose of the composition. Thirteen Sprague Dawley rats received a single intramuscular dose of 5 ml / kg of the composition. Three rats were observed for 7 days. Ten rats were observed for 14 days followed by euthanasia and necropsy. No symptoms of toxicity were observed in any group and there were no gross pathological findings in the animals that were necropsied. Based on these observations the intramuscular administration of LD50 of the composition in rats was determined to be greater than 5 rnl / kg. 30 The Ontario Veterinary College conducted another toxicity trial, in which the composition was administered to two cross-breed dogs. The protocol is summarized in the following table:
Animal Age and weight Dose 1 Dose 2 Dose interval
In each case, a dose was given in the right hind paw and the second dose 7 days later occurred in the left hind paw. Both dogs were observed for 14 days after the first injection. Appetite was monitored,
# activity, temperature, pulse rate and speed
respiratory twice a day throughout the study. The urinalysis, hematogenesis and routine serum chemistry profiles were performed at the following time points: pretreatment and 24 hours, 72 hours, 7 days and 14 days after the first injection. No animal showed signs of pain-20 associated with any injection. There was no evidence of anaphylaxis associated with the second injection. No abnormalities or changes in physical or laboratory parameters that could be attributed to the drug were observed. The drug seems to be well tolerated by healthy dogs. 25 A 17-day repeated dose study was conducted with VIRULTZINR along with a model animal study at the Ontario Cancer Institute. The female model used of C57B1 mice. There were four groups as follows (IM - intramuscular, TP - in raperitoneal): # Treatment Group Volume of dose Number / Group
Each group of mice was injected on day 0 with 5 x

weight gain and behavior were normal. In addition, there was no evidence of toxicity that caused changes observable by the light of the microscope in any of the organs examined, which were: large intestine, spleen, stomach, pancreas, urinary bladder, liver, brain, kidneys, intestine
thin and heart. The consumption of food and behavior were normal. The weight gain was normal. A repeated dose toxicity study was conducted for 13 weeks in Fischei-344 rats (total of 40 males and 40 females) to which VTRULIZINR IM was administered three
Or H times a week for 13 weeks. The largest dose was 1.1 ng / kg, approximately 20 X the human dose. The animals were subjected to complete histopathology after 13 weeks. The only discovery that was observed related to the treatment was a small decrease in obtaining
average body weight in the 20 X dose group compared to the controls. Mo toxicity was demonstrated,

This example illustrates the results of an Open Phase II clinical study conducted with cancer patients.
"5 In 1988, an Open Phase clinical trial was started
II at the General Hospital of Mont eal and extended to the Sas Atoon Cancer Center in 1989 under the diron of Maksyrniuk.
The experiment remains open to patients with various tumors
T F advanced solids that have or have not had treatment

Cooperativa del Este ("ECOG"), quality of life and survival. As of March 31, 1994, 99 patients had been treated. Adverse events were generally mild to moderate. Five patients discontinued treatment due to adverse events. No complete or partial responses were observed, although 18 patients achieved the stabilization of their disease. With respto the clinical end points, there was no change or improvement after 8 weeks of treatment with VIRULIZINTM in quality of life, pain and performance status according to ECOG in 51%, 78% and 56% H, respvely for those patients when their data were available. A subgroup of patients (n = 12), K¡ treated with VIRU-IZIN1"1 * of advanced pancreatic cancer, exhibited a one-year survival rate from the date of treatment with VIRULIZINMR of 29% with an average survival of 160 days This group exhibited a survival rate of 5 years from the date of diagnosis of 38% compared to 13.8% of historical controls, therefore, the results of the Phase II clinical study have been consistent with tests in 'ß vitro and with animals: Virulizin is effve to an appreciable degree for cancer therapy.
EXAMPLE 19
This example illustrates the methods and results of the clinical studies on Pancreatic Cancer, in particular a Phase II experiment (Protocol C02-104) with the composition of the invention for patients with pancreatic cancer, checked by biopsy and measurable. The treatment consisted of the composition prepared as in Example 1, 0.11 ml / kg (minimum dose of 7.5 ml) administered in a single deep intramoscular injon to the gluteus maximus, alternating the buttocks with each dose. Patients received 3 injons during the first week followed by injons twice a week until the progression of the tumors. The response was defined using common criteria, as cited by Miller et al., Cancer, 47, 207-214 (1981). A complete response (CR) was defined as the complete disappearance of all evidence of disease for at least 4 weeks. A partial response (RP) was defined as a reduction of at least 50% in the product of two maximum perpendicular diameters of the measurable lesion áxia, without other injuries or progression of any injury, for at least 4 weeks. Progressive disease was defined as an increase of 25% or more in the size of one or more lesions or the appearance of other lesions. The disease that did not meet the criteria for response or progressive disease was called stable disease. A total of 22 patients were enrolled in the study, but five patients were considered invaluable in terms of efficacy. There were no complete or partial answers. Three patients had progression of the disease within the first month. Six patients presented stabilization of the disease for more than 3 months (ie, 3.5, 3.5, 5, 8, 12+ and 14+ months). The average survival of the entire group was 8 months from the date of diagnosis and 5 months from the start of treatment. A patient with hepatic metastases verified by biopsy and a CEA level of 37 ng / nl (normal is less than 3 ng / ml), had absolute stabilization of liver metastases and a CEA level for 8 months. One had stable disease for 5 months. One patient relapsed in her pancreatic base 4 months after a Wfc Uhipple procedure and has been stable using the composition for at least one year, with the exception of a delayed but growing CEA. A percutaneous gauze was inserted into a third patient and he continued to work full time for at least 14 months without any evidence of tumor progression. All 22 patients were assessed for toxicity, having received a total of more than 500
-9pr injections. None revealed any clinical evidence or
toxicity laboratory realaciled with the drug. There was no detrimental effect on the Quality of Life that was generally connected with the activity of the disease. No significant changes were seen in total white blood cell counts or absolute lymphocyte counts
on serum immunoglobulins. Figures 6 and 7 show, respectively, JHf the survival curves that represent the survival times from the diagnosis and the initiation of the treatment. For comparison, a historical survival curve of Gudjonsson (1987) has been superimposed in Figure 6. Another example of a historical curve of comparable history can be found in Bakkevold, Petterson, Arnesjo and Espenhaug (1990). The results of the 25 survival analyzes are summarized below: The continuous line represents the survival curve of the patients treated with the composition of the invention and the interrupted line represents the historical survival curve (Balen et al., 165- 187 S 499-508, Lippincott Co., Philadelphia, Penn.). The survival of all patients treated with the composition of the invention, including patients with one to more tumor sites, is shown in Figure 8. Survival of patients with two tumor sites and with three or more tumor sites is shows ufe in Figures 9 and 10, respectively. The group of all patients treated with the composition of the invention had a 39% survival (estimated Kaplan-fleier) in one year- The degree of survival in one year for all patients with advanced malignant melanoma (rirlA) is of approximately 1.1% in the controls
historical (equivalent in number of tumor sites). The group had a median survival of 315 days compared to the historical median of 89 days. For patients with two tumor sites, one-year survival was 49% in the treated patients
with the composition of the invention, compared to 13% in historical controls. This group had a median survival of 360 days compared to the historical median of 120 days. With three or more tumor sites the survival rate of one year was 31% in patients treated with the composition of
the invention, compared to 0% of historical controls. The group with three or more tumors had a median survival of 205 days compared to the historical median of 60 days. Quality of life was assessed by weight recovery, performance status (K rnofsky), quality of life index (Spitzer) and a pain scale (Linear Analogue). Weight recovery is shown during the time in The following table:

The scales of Karnofsky and Spitzer are both
subjective and found that they agreed approximately in each individual. Fifteen patients reported no change in these parameters. Four patients presented fluctuations that subsequently returned to previous levels. One patient had a decrease (of 40-20%). O H The results of the pain assessment for six patients showed that in week 4 the pain decreased from 5 (the worst possible) to 2 (moderate) or 0 (no pain). One patient had a pain reduction of 3 to 0. One patient with liver metastasis had pain reduction at 0 and
stabilization for 11 months. Nine patients who registered in the study with pain or maintained that level through the study. Five patients had a moderate increase (2 units) of pain. Three patients had transient pain increases (1 to 2 units) during the second or third rnes. 5 Of 1,734 injections administered to 33 patients, 21 patients had no adverse drug reactions. It was reported about 14 adverse reactions of the drug in twelve patients. Adverse reactions of the drug occurred usually at weeks 8 and were mild to
transient and very often of a low grade fever. The difference in survival between the historical groups and the protocol groups treated with the composition of the invention suggests a survival benefit for patients treated with the composition of
the invention. It seems that the cancer was stabilized in nineteen patients. All patients treated for UMA were included in the survival data. Twenty-one previously treated patients were also included (many clinical trials required untreated patients, due to poor prognosis
of the previous failed treatments). The burden of tumors in this population was high (82% had more than one rnetastatic site). Data on survival and quality of life suggest that the majority of patients received some
benefit of the treatment. Eleven patients were still alive at the end of the study period and of those eleven, five continued treatment. The preliminary analysis in thirty-three patients demonstrated a survival rate of one year (from the diagnosis of relapse) of 39%. After the conclusion of the study, 5 final data were available for forty-five patients. Forty-one of these patients had distant metastases. The survival rate in one year from the diagnosis of distant metastasis for these patients was 61%, with a median survival of 529 days (17.6 months). 0 This can be compared to the survival degree of 13% (median of 92 days) from the historical data. The survival rate of one year after initiation with VIRULIZTNMR for all patients was 22%, with a median survival of 200 days (5.7 months). 5 Quality of life, pain and performance status according to FCOT showed no change or improvement during the first 8 weeks of treatment in 63%, 93% and 70% of patients respectively for whom data were available. In addition, the pathology of tumors before and after the application of VIRULIZINMR showed an unusual pattern of tumor cell necrosis, fibrosis and vascular thrombosis consistent with the effects mediated by TNF-ct.
EXAMPLE 21 5 This example illustrates a pathology protocol directed at malignant melanoma. The following is a report of an elderly 73-year-old woman with progressive malignant melanoma of the palate and gums. Two views of malignant melanoma under the microscope were observed. Looking up and down, you can see the epithelial layer with the accompanying keratin, within which malignant cells begin to become more evident. These cells can be seen to be round or oval, with a

The blood vessels that appear normal and there is a shortage of any kind of inflammatory / immune response as it would be represented by the presence of leukocytes (polymorphonuclear cells and rnononuclear cells). This is an example of
tumor tissue that is progressing, that is, the tumor architecture is intact. A sample of tumor tissue from the same patient, which had been treated with the composition for 2 months, was observed. Starting from top to bottom, you can see that the
The continuity of the epithelium has been destroyed by a necrotic process. This necrosis, while common in the center of any turnor that has reached a critical mass, is rarely seen in the periphery, especially the malignant melanoma and is a sign that the host immune response is rising
to attack with the tumor. Throughout the fo or there is a massive number of preferred cells of the original cells fl_ of the turnor. These are immune cells, including neutrophils, lymphocytes, macrophages that have organized the destruction of the typical tumor architecture. The walls of the blood vessels have infiltrated thickly with a large number of cells.
immune cells of the host. This cellular infiltrate will subsequently cause the destruction of the blood vessel which at the same time prevents the tumor from receiving its supply of nutrients and oxygen (ischemic necrosis). This immune response that ÉU contributed to the turnoral disorganization seen in the
slides with the patient's tissue is consistent with the informed changes that are known to be produced by TNF
(tumor necrosis factor) and with the work results described in the previous examples. The immune response showed in the treatment
Subsequent with the composition in the holder strongly links the immune modulation of TNF in vitro by the composition with the known effects of antitumor turbid TNF in vivo.

40 These results show that the turnoricidal activity provoked by VIRULIZIN ™ in the monocytes of cancer patients was equal to or greater than the activity produced in the response to a combination of conventional activators of macrophages (TFN-cf and LPS). VTRULIZTNMR can also stimulate the function of your oricide in rnacrophages obtained from patients with HIV with Kaposi's sarcoma, even in very early stages of the disease. In this way, the action of VTRULIZINMR appears to be independent of collaboration with other types of immune cells, including helper T lymphocytes.

to dryness in a rotating vaporizer in which 1 ai. Bath temperature did not exceed 40 ° C. To ensure that the solution remained basic during evaporation, 5 drops of a concentrated solution of ammonium hydroxide were added every half hour to the composition until the evaporation was complete. The resulting residue had a weight of 11.6 g. 20 ml of a concentrated solution of hydroxy or 10% ammonium in methanol was subsequently added to 2 g of the above residue. The insoluble material was filtered and the filtrate was chromatographed through 101.93 g of M? vaporization of 60 fl in a column with dimensions of 5 ern x
12.5 ern »The solvent system used was concentrated solution of 10% ammonium hydroxide in methanol. The column was operated at a pressure of 0.703 g / crn2 and a flow rate of 11 l / rnin. After 100 rnl of the solvento passed through the column, 12 fractions of 20 ml were collected. The
Collection of these fractions was correlated with the appearance of a whitish band that moved rapidly down the column. The thin layer chromatography (CCD) of these fractions was carried out on silica gel plates in a
concentrated solution of 10% ammonium hydroxide in methanol and visualized with a ninhydrin spray. Fractions that had similar CCD profiles were combined, resulting in the following fraction combinations, which were dried in a rotary vaporizer:

EXAMPLE 29
This example illustrates an expanded procedure for isolating active fractions. Example 28 was repeated on a larger scale as follows: 10 ml of a concentrated solution of 10% ammonium hydroxide was added to 900 nl of the composition and the solution
The resulting solution was evaporated to dryness in a rotary evaporator in which the temperature of the bath did not exceed 40 ° C. To ensure that the solution will remain basic during evaporation, 5 drops of a concentrated solution of ammonium hydroxide were added every half hour to the
composition until complete evaporation, leaving a residue. 150 rnl of a concentrated solution of 10% ammonium hydroxide in methanol was subsequently added to the total residue. The solution was treated with sound for 15 minutes and the insoluble material was filtered. The filtrate was chromatographed through 1695 g of 60fl vaporizer silica gel in a column with dimensions of 30 ern x 12 crn. The solvent system used was concentrated solution of 10% ammonium hydroxide in methanol. The column was subjected to a pressure of 0.422 kg / cm2 and a flow rate of 30 rnl / rnin.

All combinations of fractions 15-16 to fractions 31-34 had a positive reaction with ninhydma at an Rf value of 0.87, a value very similar to the value of Rf for the active fractions of example 28. Fractions 24- 30 and 31-34 had an additional positive reaction with
40 ninhydrin at a Rf value of 0.85. Fractions 4-5, 15-16 and 17-18 were tested in vitro for stimulation of TNF (according to example jB 9), resulting in no FNT stimulation activity. The elemental analysis of the previous fractions showed that its NH4Cl content was high, which is known to inhibit the production of TNF. 5 Samples from fractions 15-16 and 24-30 were dialysed and then analyzed by mRNA spectroscopy, using the methods described in Example 28. The non-dialyzed mixtures of fractions 17-18 and 24-30 also they were analyzed. A review of the resulting spectra
indicated that the following compounds were present: glycocholic acid, a trimer of t-rihexosamine and taurocholic acid (fractions 15-16); stearic acid and a hexosamine diol; and glycolic acid (fractions 24-30).
EXAMPLE 30
This example illustrates the application of additional methods for fractionating and analyzing the active compounds of the inventive composition. 20 Having identified that the activity of releasing TNF, IL-lß and GM-CSF can be precipitated, in part, by means of 80% acrylonitrile and that much of the release activity elutes early from CLAR-FI Cis, the physical and chemical properties of the precipitated fraction have been
studied and compared with the whole composition and the supernatant fraction of the composition.
Figure 11 shows an elect rhoresis of SDS gels of the entire composition and the precipitates and supernatants of the composition. In all three cases, the composition runs close to the SDS front, indicates a low molecular weight. The rnas parameter
small used was 14,400 daltons. The molecular size of the composition was also examined to determine its elution time from a molecular sieve HPLC column. The elution times of
The entire composition, precipitate and supernatant were compared
with the parameters. All three eluted later than insulin, which eluted at 24.5 minutes. Once again, the physicochemical analysis gives a molecular weight of less than 2,400 daltons. The TNF release component elutes early-
this way a column with the opposite effect was chosen, a hydrophilic column in the presence of organic solvents. The ideal elution conditions for the polyhydroxyethyl column are 80% acetonitrile. However, as indicated in the previous example, some of the substances in the
The preparation was precipitated at this concentration. Accordingly, the composition was analyzed at a concentration t > acetonitrile where the column works mainly co or a molecular sieve column. Figures 12 and 13 show the profile of the entire supernatant and the
precipitate. The front sheet summarizes the elution time for the different peaks. The elution times indicate that the f ß active component of the composition has an inolecular weight b jo. The composition and its precipitate and supernatant were separated by CLAR ion exchange. So much for
The chromatography medium AX300 (anion exchange), or by CMX 300 chromatography (cation exchange), had no significant separation of the components. The hydrophobic reverse phase chromosome did not separate the peaks.
J f In another series of experiments, 10 rnl of VTRULIZINMR
were loaded onto a chromatographic column by anion exchange (Bio-Rad AG-1, hydroxide form, the total resin wet volume was 10 rnl, equilibrated with Millipore deionized water). The volume of the resin was calculated as sufficient for the binding of all the anions present in the extract.
The unbound fraction was collected and reloaded on the column to maximize the bond to the resin. The unbound fraction of this second passage was collected and stored. Any unbound material that remained in the empty volume of the column was removed by washing with water
deionized (2 X-20 nl). The ligated molecules were eluted with a gradient of steps of ammonium bicarbonate, 20 l / step. The ammonium bicarbonate was removed in free form by lipophilization. The samples of all fractions were tested to verify the TNF release activity in
the rnonocito activation test / rnacró ago. The TNF release activity was not found in the unbound fraction (effluent), but the majority was found in eluate eluted with 0.2 M ammonium bicarbonate. These results indicate that the active components are polar, ammonic and acidic in nature. . The samples of all the fractions were analyzed to verify the stimulation activity of the TNF, according to the procedures of example 2. The results are shown below:

The results of the activity tests show that the stimulation of TNF production was discovered in the fractions of 0.2 M and D.4 M. The composition was subjected to dialysis and dialysis drying, as follows: 100 nl in the The composition was placed inside a CE Spectra / PorR membrane tube that had a molecular weight cutoff of LOO. The ends of the tube were sealed with clips and the tube was placed in a stirred barium of 10 L of distilled water. The dialysis was monitored daily by removing 1 ml of the solution from the dialysis tube 5 and adding 3-4 drops of a silver nitrate solution to 1/10 N. The presence of chloride indicated that the dialysis was not complete. If the dialysis was not complete the bath was replaced with fresh distilled water. The completion of the dialysis occurred after 3-4 days. After ia
After the dialysis was completed, the dialyzed material was dried on a rotary evaporator to produce an average of 0.3 g of solid per milliliter of the original volume. A sample of the solid material was then dissolved in water grade CLAR, and the CCD was carried out on plates of
silica gel in a concentrated solution of 10% ammonium hydroxide in methanol, and visualized with a spray of nmhidrma. A positive reaction with mnhydpna was obtained at an Rf of 0.83. A sample of the solid material was also analyzed
by means of mRNA spectroscopy, using the methods described in example 28. A review of the resulting spectra indicated that the following compounds were present: a conjugate of sputum-oleic acid, diacetyl sialic acid, a dimer of fucose-hexosam a, cocolic deoxigli acid, acid
taurocholic, a day of sialic acid fucose and a trimer of d? (Fucose) hexosarnine.
