This invention is related to a recombinant super-compound interferon (rSIFN-co) with changed spatial configuration. One characteristic of rSIFN-co in this invention is that it cannot only inhibit DNA. (deoxyribonucleic acid) duplication of the '5 hepatitis B virus but also the secretion of HBsAg and HBeAg. BACKGROUND OF THE INVENTION IFN-con is a new interferon molecule constructed with the most popular conservative amino acid found in natural human '-IFN 30 subtypes using genetic engineering methods. United States Patent Nos. 4,695,623 and 4,897,471 have described it. IFN-con had been proven to have broad-spectrum IFN activity and virus and tumor-inhibition and natural killer cell activity. United States Patent No. 5, 372, 808 .by Amgen, Inc. addresses' treatment 35 Infergen*(interferon alfacon-1) . Chinese Patent No. 97193506.8 by Amgen, Inc. addresses re-treatment of Infergen*(interferon alfacon-1) on-hepatitis C. Chinese Patent No. 98114663.5 by - la - Shenzhen Jiusheng Bio-engineering Ltd. addresses recombinant human consensus interferon-a treatment for hepatitis B and hepatitis. C. 5 The United States Food and Drug Administration (FDA) authori-zed Amgen to produce Infergen*(interferon alfacon-1) with E. Coli. for clinical hepatitis C treatment at the end of 1997. Hepatitis B patients can be identified when detecting HBsAg and 10 the HBeAg. a-IFN is commonly used in clinics to treat hepatitis B. IFN binds superficial cell membrane receptors, inhibiting DNA and RNA (ribonucleic acid) duplication, including inducing some enzymes to prevent. duplication of the virus in hepatitis infected cells. All IFNs can inhibit only the DNA duplication 15 of viruses, not the e and s antigen. This disclosure describes recombinant. super-compound interferon, method to produce the same and uses thereof. 20 Af outbreak-5f atypical * pneumonia, ref! rrecT tbo'~-s sdeiVre~d aute~ respiratory syndrome (SARS) and first identified in Guangdong Province, China, has spread to several countries. Similar cases were detected in patients in Hong Kong, Vietnam, and Canada from February and March 2003. The World Health Organization (WHO) issued a global alert for the illness. In mid-March 2003, SARS was recognized in health care workers and household members who had cared for patients with severe respiratory illness in the Far East. Many of these cases could be traced through multiple chains of transmission to a health care worker from Guangdong 30 Province who visited Hong Kong, where he was hospitalized with pneumonia and died. By late April 2003, thousands of SARS cases. and hundreds of SARS-related deaths were reported to WHO froin over 25 countries around the world. Most of these cases occurred after exposure to SARS patients in household or health 35 care settings. This disclosure provides a method to prevent and/or treat SARS. -2- Another current epidemic scare in Asia is the avian influenza virus (H5Nl) . Avian influenza is an infectious disease in birds caused by type A strains of the influenza 5 virus. There are 15 avian influenza virus subtypes; H5N1 is of particular concern because it mutates rapidly infecting not just animals, but humans. The confirmed human death count from avian influenza, as of February 4, 2004, stood at thirteen. Laboratories in the WHO global influenza 10 network have been working to control the virus and prevent further human deaths. However, to fully understand the magnitude of H5N1 and its ways of distribution, more meticulous testing is needed. Furthermore, antiviral drugs are only effective in treating or preventing influenza A 15 virus strains against those who are of fair health. See -http://www.who.int/csr/don/2004_01.15/en, January 15, 2004. Researchers at St. Jude and other top influenza laboratories are racing to create a prototype human vaccine 20 against H5N1. They hope that prototype vaccines can be ready in as little as three weeks. Nevertheless, until a vaccine is created, scientists are worried that H5N1 may develop into a human superflu. See The Wall Street Journal, Scientists Rush to Create Vaccine for Bird Flu - Just in 25 Case, January 28, 2004. This disclosure describes recombinant super-compound; interferon, method to produce the same and uses thereof. Particularly, the super-compound interferon disclosed 30 herein is capable of inhibiting, preventing and/or treating the hepatitis viruses, SARS virus, or virus-induced upper respiratory diseases, and the avian influenza virus. -3- When used in this specification and claims, the terms "comprises" and "comprising' and variations thereof mean that the specified features, steps or integers are included.

4 , pH7.0. Infergen* (interferon alfacon-1), made by Amgen Inc., also 25 known as consensus interferon, is marketed for the treatment of adults with chronic hepatitis C virus (HCV) infections. It is currently the only FDA-approved, bio optimized interferon developed through rational drug design and the only interferon with data on the label specifically 30 for non-responding or refractory patients. InterMune's sales -force re-launched Infergen* in January 2002 with an active campaign to educate U.S. hepatologists about the safe and appropriate use of Iifergeri,. which represents new hope for the more than 50 percent of HCV patients who fail 35 other currently available therapies.

The X-ray Diffraction of rSIFN-co Crystal -9- DETAILED DESCRIPTION OF THE INVENTION This invention provides a method for producing a recombinant super-compound interferon with changed spatial 5 configuration and enhanced antiviral activity comprising steps of: (a) Introducing nucleic acid molecule which codes for said interferon with preferred codons for expression to an appropriate host; and 10 (b) Placing the introduced host in conditions allowing expression of said interferon. This invention provides the method for producing interferon, further comprising recovery of the expressed 15 interferon. This invention provides a recombinant super-compound interferon or an equivalent thereof with changed spatial configuration. This invention reveals that proteins with 20 the same primary sequence might have different biological activities. As illustrated in the following example, this invention discloses two proteins with identical amino acid sequences but with different activities. The efficacy of this activity may sometimes be improved and, sometimes, the 25 protein with changed spatial configuration would reveal new function. An equivalent is a molecule which is similar in function to the compound interferon. An equivalent could be a 30 deletion, substitution, or replacement mutant of the original sequence. Alternatively, it is also the intention of this invention to cover mimics of the recombinant super compound interferon. Mimics could be a peptide, polypeptide or a small chemical entity. 35 The interferon described herein includes but is not limited to interferon a, P, or w. In an embodiment, it is IFN-la, -10- IFN-2b or other mutants. In an embodiment, the super-compound interferon disclosed has higher efficacy than the interferon described in U.S. 5 Patent Nos. 4,695,623 or 4,897,471. This super-compound interferon is believed to have unique secondary or tertiary structure. (See e.g. Figure 6.) The super-compound interferon described herein has spatial 10 structure change(s) resulting from the changes of its production process. The above-described super-compound interferon may be produced by a high-efficiency expression system which uses 15 a special promoter. In an embodiment, the promoter is PMD. As could be easily appreciated by other ordinary skilled artisans. Other inducible promoters, such as heat shock promoters or heavy metal inducible promoters, may be used in this invention. 20 The super-compound interferon may also be produced with its gene as artificially synthesized cDNA with adjustment of its sequence from the wild-type according to codon preference of E. Coli. Extensive discussion of said codon 25 usage (preference) may be found in U.S. Patent No. 4,695,623. See e.g. column 6, line 41 - column 7, line 35. The above-described super-compound interferon possesses anti-viral or anti-tumor activity, and; therefore, is 30 useful in inhibiting, preventing and treating viral diseases, tumors, or cancers. As used herein, viral diseases include, but are not limited to, hepatitis A, hepatitis B, hepatitis C, other types of 35 hepatitis, infections caused by Epstein-Barr virus, Cytomegalovirus, herpes simplex viruses, other herpes viruses, papovaviruses, poxviruses, picornaviruses, adenoviruses, rhinoviruses, human T-cell leukemia virus I, human T-cell leukemia virus II, or human T-cell leukemia virus III. 5 Viral upper respiratory infection, alternative names common cold, colds. This is a contagious viral infection of the upper respiratory tract characterized by inflammation of the mucous membranes, sneezing, and a sore throat. It is usually caused by over 200 different viruses, known as 10 rhinoviruses. Colds are not caused by the same viruses responsible for influenza. Colds are spread through droplets from the coughing or sneezing of others with a cold or by hand contact with objects contaminated by someone with a cold. The incidence of colds is highest 15 among children, and the incidence decreases with age because immunity to the virus causing the cold occurs after the illness. Gradually, immunity to a wide variety of viruses that cause colds is developed in adults. Children may have 10 colds a year, and adults may have 3 colds a 20 year. The U.S. Centers for Disease Control and Prevention have estimated that the average annual incidence of upper respiratory tract infections (URIs) in the United States is 25 429 million episodes, resulting in more than $2.5 billion in direct and indirect healthcare costs. The common cold is most often caused by one of several hundred rhinoviruses (52%), but coronaviruses (8%) or the 30 respiratory syncytial virus (7%) may also lead to infection. Other viruses, such as influenza (6%), parainfluenza, and adenoviruses, may produce respiratory symptoms, but these are often associated with pneumonia, fever, or chills. 35 Colds occur in a seasonal pattern that usually begins in mid-September and concludes in late April to early May. The -12common cold is quite contagious and can be transmitted by either person-to-person contact or airborne droplets. Upper respiratory symptoms usually begin 1 to 2 days after exposure and generally last 1 to 2 weeks, even though viral 5 shedding and contagion can continue for 2 to 3 more weeks. Symptoms may persist with the occurrence of complications such as sinusitis or lower respiratory involvement such as bronchitis or pneumonia. 10 The common cold has a variety of overt symptoms, including malaise, nasal stuffiness, rhinorrhea, nonproductive cough, mild sore throat, and, in some cases, a low-grade fever. Because of the- similarity of symptoms, a cold may be mistaken for perennial allergic rhinitis, but allergies can 15 usually be ruled out because of the differences in chronicity. If a patient presents with a viral URI, the spectrum of remedies is extensive. Since most of these infections are 20 self-limiting, clinicians usually recommend rest and fluids, but other treatments include environmental and nutritional therapies, over-the-counter and prescription decongestant and antihistamine products, new antihistamine and anticholinergic nasal formulations, and antibiotics. 25 Table 1 lists commonly used cough and cold medications and their side effects.

A main cause of URI in adults is from rhinovirous. For children, respiratory syncytical virus and parainfluenza virus are two leading causes of URI. 15 Super-compound interferon plays an important role in the -14fight against virus that causes URI. Super-compound interferon gains its . anti-virus affects mainly via two mechanisms: 1. Attach to surface of sensitive cells and induce them 5 to produce anti-virus protein, then block the duplication and reproduction of viruses in vivo. 2. Super-compound interferon can adjust immune response, including T-cell immune response, activity of NK cell, the phagocytosis function of monokaryon, and even 10 formation of some antibodies in vivo. In treatment for URI, Super-compound interferon can be directly applied to the affected area via a spray inspiration. This method of treatment allows the interferon 15 to reach the target cells first hand. Consequently, marketing the supply as a spray, rather than via oral or injection, would be safer and more effective for administrating the interferon. 20 Usage of Super-compound Interferon to Prevent or Treat SARS With the consent of the Sichuan working group on SARS prevention and control, the distribution of Super-compound interferon began in May of 2003. Super-compound interferon spray was allocated to doctors and nurses in 25 hospitals, populated areas with a high risk for SARS, and to the National research group on prevention and control of SARS. Among the 3,000 users as of December 19, 2003, there were no reports of any side effects connected to the use of the spray. Furthermore, none of the 30 doctors and nurses, the people of Sichuan Province, or other organizations that have used the Super-compound interferon spray has been infected by SARS. Therefore, this invention provides a method for inhibiting, 35 preventing or treating virus replication or virus-infected cells by contacting said virus or infected cells with an effective amount of the super-compound interferon or its -15equivalent. This super-compound interferon is useful in inhibiting, preventing or treating the following cancers or tumors: 5 Basal Cell Carcinoma Skin Cancer Malignant Melanoma Renal cell carcinoma Liver Cancer Thyroid Cancer Rhinopharyngeal Cancer Prostate Cancer Stomach/Abdominal Cancer Solid Carcinoma Esophageal Cancer Cancer Rectal Cancer Pancreatic Cancer Breast Cancer Ovarian Cancer & Superficial Bladder Cancer Hemangioma Cervical Cancer Epidermoid Carcinoma Non-small Cell Lung Cancer Small Cell Lung Cancer Glioma Malignant Acute Leucocythemia Leucocythemia Hemal Chronic Leucocythemia Disease Chronic Myelocytic Leukemia Hairy Cell Leukemia Lymphadenoma_ Multiple Myeloma -16- Polycythemia Vera Others Kaposi's Sarcoma Patient #1. A . female patient with ovarian cancer started receiving injections. She received 15pg injections on July 14 July 1 6 th, July l8th, July 20 th, and July 22 nd. On July 14 th, 5 2000ml of peritoneal fluid was observed. The patient underwent chemotherapy on July 22 "d. On August 3 rd, the patient's peritoneum was opened. More than 2000ml of fluid was expected to be found, but only 200ml of fluid was observed. The left and right ovaries and lymphatic nodes were cancerous. All other organs were clear. Patient #2. A kidney cancer patient was treated in the following manner. In a half-month period, the patient was given 3 injections of 9pg of rSIFN-co and 3 injections of 15pg of 15 rSIFN-co. I.n the one full month following these injections, he received 9pg and 15pg injections of rSIFN-co every other day. A kidney biopsy showed ~ no ~ metastasis after 'this cdurse of treatment. The patient showed a full recovery. Every half year after recovery, the patient received 15pg injections of rSIFN 0 co 15 times over a one-month period. Accordingly, this invention provides a method for inhibiting tumor or cancer cell growth by contacting the super-compound interferon or its equivalent with said tumor or cancer cells. 25 In a further embodiment, the super-compound interferon inhibits the DNA duplication and secretion of HBsAg and HBeAg of Hepatitis B Virus. 30 This invention also provides artificial gene codes for the super-compound interferon or its equivalent. It is within the ordinary skill to design an artificial gene. Many - 17 methods for generating nucleotide sequence and other molecular biology techniques have been described previously. See for example, Joseph Sambrook and David W. Russell, Molecular Cloning: A laboratory Manual, December 5 2000, published by Cold Spring Harbor Laboratory Press. This invention provides a vector comprising the gene which codes for the super-compound interferon or its equivalent. 10 This invention provides an expression system comprising the vector comprising the gene which codes for the super compound interferon or its equivalent. The cells include, but are not limited to, prokaryotic or eukaryotic cells. 15 This invention also provides a host cell comprising the vector comprising the gene which codes for the super compound interferon or its equivalent. This invention provides a process for production of 20 recombinant super-compound interferon comprising introducing an artificial gene with selected codon preference into an appropriate host, culturing said introduced host in an appropriate condition for the expression of said compound interferon and harvesting the 25 expressed compound interferon. The process may comprise extraction of super-compound interferon from fermentation broth, collection of inclusion body, denaturation and renaturation of the harvested 30 protein. The process may maintain the high efficacy even when the super-compound interferon is used with an agent and in a particular concentration. The process also comprises 35 separation and purification of the super-compound interferon. The process further comprises lyophilization of the purified super-compound interferon. The process -18comprises production of liquid injection of super-compound interferon. This invention also provides the produced super-compound 5 interferon by the above processes. This invention provides a composition comprising the recombinant super-compound interferon or its equivalent and a suitable carrier. 10 This invention provides a pharmaceutical composition comprising the recombinant super-compound interferon or its equivalent and a pharmaceutically acceptable carrier. 15 This invention provides a method for treating or preventing viral diseases or tumors in a subject comprising administering to the subject an effective amount of the super-compound interferon or its equivalent. 20 This invention provides the above-described method wherein the viral diseases include, but are not limited to, hepatitis A, hepatitis B, hepatitis C, other types of hepatitis, infections of viruses caused by Epstein-Barr virus, Cytomegalovirus, herpes simplex viruses, or other 25 type of herpes viruses, papovaviruses, poxviruses, picornaviruses, adenoviruses, rhinoviruses, human T-cell leukemia viruses I, or human T-cell leukemia viruses II, or human T-cell leukemia virus III. 30 This invention provides the above-described method wherein super-compound interferon was administered via orally via vein injection, muscle injection, peritoneal injection, subcutaneous injection, nasal or mucosal administration, or 35 by inhalation via an inspirator. This invention provides the above-described method wherein super-compound interferon was administered following the -19protocol of injections of 9pg or 15pg every two days, 3 times a week, for 24 weeks. It was surprising to find that rSIFN-co, the spatial 5 structure of which has been changed, is not only a preparation to inhibit the DNA duplication of hepatitis B, but to inhibit the secretion of HBsAg and HBeAg on 2.2.15 cells. 10 One objective of this invention is to offer a preparation of rSIFN-co to directly inhibit the DNA duplication of hepatitis B viruses and the secretion of HBeAg and HBsAg of hepatitis B and decrease them to normal levels. 15 In one embodiment, rSIFN-co was produced with recombinant techniques. On the condition of fixed amino acid sequence, the IFN DNA was redesigned according to the E. Coli. codon usage and then the rSIFN-co gene was artificially synthesized. rSIFN-co cDNA was cloned into the high 20 expression vector of E. Coli. by DNA recombinant techniques, and a high expression of rSIFN-co was gained by using of induce/activate-mechanism of L-arabinose to activate the transcription of PD promoter. 25 Compared with usual thermo-induction, pH induction and IPTG induction systems of genetic engineering, arabinose induction/activation system has some advantages: (1) Common systems relieve promoter function by creating a "derepression" pattern. Promoters then induce downstream 30 gene expression. Temperature and pH change and the addition of IPTG cannot activate promoters directly. In the system disclosed herein, L-arabinose not only deactivates and represses but also activates the transcription of PD promoter which induces a high expression of rSIFN-co. 35 Therefore, the arabinose induction/activation system is a more effective expression system. (2) The relationship between Exogenous and L-arabinose dosage is linear. This means the concentration of arabinose can be changed to -20adjust the expression level of the exogenous gene. Therefore, it is easier to control the exogenous gene expression level in E. Coli. by arabinose than by changing temperature and pH value. This characteristic is 5 significant for the formation of inclusion bodies. (3) L arabinose is resourceful, cheap and safe, which, on the contrary, are the disadvantages of other inducers such as IPTG. 10 This embodiment creates an effective and resistant rSIFN co-expressing E. Coli. engineering strain with an L arabinose induction/activation system. The strain is cultivated and fermented under suitable conditions to harvest the bacterial bodies. Inclusion bodies are then 15 purified after destroying bacteria and washing repeatedly. The end result, mass of high-purity, spatial-configuration changed rSIFN-co protein for this invention and for clinical treatment, was gained from denaturation and renaturation of inclusion bodies and a series of 20 purification steps. The following are some rSIFN-co preparations: tablets, capsules, liquids for oral consumption, pastes, injections, sprays, suppositories, and solutions. Injections are 25 recommended. It is common to subcutaneously inject or vein inject the medicine. The medicine carrier could be any acceptable medicine carrier, including carbohydrates, cellulosum, adhesive, collapse, emollient, filling, add dissolving agent, amortization, preservative, thickening 30 agent, matching, etc. This invention also provides a pharmaceutical composition comprising the above composition and a pharmaceutically acceptable carrier. 35 For the purposes of this invention, "pharmaceutically acceptable carriers" means any of the standard pharmaceutical carriers. Examples of suitable carriers are -21well known in the art and may include, but are not limited to, any of the standard pharmaceutical carriers, such as a phosphate buffered saline solution and various wetting agents. Other carriers may include additives used in 5 tablets, granules, capsules, etc. Typically such carriers contain excipients such as starch, milk, sugar, certain types of clay, gelatin, stearic acid or salts thereof, magnesium or calcium stearate, talc, vegetable fats or oils, gum, glycols or other known excipients. Such carriers 10 may also include flavor and color additives or other ingredients. Compositions comprising such carriers are formulated by well-known conventional methods.

Name one of the positive recombinant plasmid pHY-5, and name the strain containing pHY-5 plasmid PVIII. Amplify and store 15 the positive strain with glycerol in -80*C. High expression of rSIFN-co gene in E. Coll. In pHY-5 plasmid, rSIFN-co gene is under the control of strong promoter PB. This promoter is positively and negatively regulated by the product of the gene araC. AraC 20 is a transcriptional regulator that forms a complex with arabinose. In the absence of arabinose, the AraC dimer binds 02 and Ii, forming a 210bp loop. This conformation leads to a complete inhibition of transcription. In the presence of arabinose, the dimer is released from 02 and 25 binds I1 and 12 leading to transcription. Arabinose binding deactivates, represses, and even activates the transcription of Pm promoter, which stimulates PA, inducing high expression of rSIFN-co. rSIFN-co expression level in PVIII is more than 50% of the total E. Coli. 30 protein. -29- Summary rSIFN-co is a new interferon molecule artificially built according to the conservative amino acid of human o 5 interferon. It has been proven as an effective anti-hepatitis drug. In order to get enough pure rSIFN-co protein, a stable recombinant E. Coli. strain which highly expresses rSIFN-co protein was constructed. 10 First, according to published Infergen*(interferon alfacon-1) amino. acid sequence, E. Coli. codon was used to synthesize the whole cDNA of rSIFN-co. This DNA fragment was sequenced, proving that the 501bp codon sequence and TAA termination codon sequence are valid and identical to theocratic design. 15 Subsequent analysis revealed that the N-terminus amino acid sequence and amino acid composed of rSIFN-co produced by the recombinant strain were both identical to the prediction. The rSIFN-co cDNA was cloned into E. Coli. high-expression 20 vector pHY-4 plasmid to construct the recombinant plasmid pHY 5. E. Coli. LMG194 strain was further transformed with pHY-4 plasmid to get stable rSIFN-co high-expression transformant. This transformant was cultured for 30 generations. The heredity of pHY-5 recombinant plasmid in E. Coli. LMG194 was normal and stable, and the expression of rSIFN-co was high and steady. E. Coli. LMG194, which contains recombinant pHY-5 plasmid, is actually an ideal high-expression engineering strain. References 30 1. Blatt LM, Davis JM, Klein SB. et al.

Fermentation Inoculate the recombinant strain in LB media, shaking (200 10 rpm) under 37 0 C overnight (approximate 18 h), then add 30% glycerol to the fermentation broth to get final concentration of 15%, allotted to 1 ml tube and kept in 20T as seed for production. 15 Add 1% of the seed to LB media, shaking (200 rpm) under 37C overnight to enlarge the scale of the seed, then add to RM media with a ratio of 10%, culturing under 37C-. Add arabinose (20% solution) to 0.02% as an inductor when the OD600 reaches about 2.0. 4 hours after that, stop the 20 culture process, collect the bacteria by centrifuge, resuspend the pellet with buffer A, and keep in -20T overnight. Thaw and break the bacteria by homogenizer, then centrifuge. Wash the pellet with buffer B, buffer C, and distilled water to get a relatively pure inclusion body. 25 2. Denaturation and renaturation Dissolve the inclusion body in Guanidine-HCl (or urea) of 6 mol/L. The solution will be a little cloudy. Centrifuge it at a speed of 10000 rpm. Determine the protein 30 concentration of the supernatant. This supernatant is called "denaturation solution." Add the denaturation solution to renaturation buffer, and keep the final protein concentration under 0.3 mg/ml. It is better to add the totally denatured solution in three steps instead of one 35 step. Keep the solution overnight under 40C.

Results and Conclusion 1) At 37cC, according to data collected at designated 15 points during testing and compared with data before testing, the potency began descending from the 6 th month and the changes in the three batches were similar. The appearance of other items had no changes. 20 2) At 25cC, according to data collected at designated points during testing and compared with data before the testing, the potency only had a little change, and the changes in the three batches were similar. The appearance of other items had no changes. 25 3) At 2-8cC, according to data collected at designated points during testing and compared with data before testing, the potency of the three batches all were stable. The appearance of other items also had no changes. 30 In conclusion, it is suggested that the lyophilized powder of recombinant super-compound interferon for injection should be better stored and transported at low temperatures. Without such conditions, the product can also 35 be stored for short periods (i.e., 3 months) at room temperature. -39-- EXAMPLE 3.5 Production Flow Chart of rSIFN-co 1. Production 5 1.1 Fermentation Use mixture of LB+M9 as culturing medium. The amount of innoculum will be 1.5%. Agitate to OD600=0.4 (about 3.5 hours) under 32 0 C, then raise temperature to 42 0 C. Continue the agitation 10 for another 6 hours, the expression of rSIFN-co will reach the maximum level. The examination under scanning of the gel resulting from SDS-PAGE shows that the level of expression is up to 57%, which is the highest standard in China. 15 1.2 Purification Centrifuge the bacteria solution to collect the bacterial pellet 20 1 Physiological saline wash for two (2) times I Adding buffer (50mM Tris-HCl, 1mM EDTA, 100mM NaCl, 1% Triton X-100, 1-2 M Urea), sonication to 25 disrupt bacterial cells for 20-30 minutes I Precipitate the buffer solution and wash a few times until the color turns into pure white 30 Use 7M Guanidine HCl to denature Dilute the Guanidine HCl to renature, stay overnight 4 35 Use Sephadex G25 to desalt I Use 0.1 M NaCl to apply CM-Sepharose -40- Do stepwise elution to collect the active peak I After the active peak is desalted, apply to HPLC 5 positively charged column Use 0.1 M NaCl to do stepwise elution, collect active peak which is the product of rSIFN-co 10 Add protection carrier and lyophiling agent Separate lyophilized materials (rSIFN-co) The purity of the product (rSIFN-co) from this production 15 procedure is shown to 95% under the test of SDS-PAGE where molecular weight is 14.5 Kda. The reverse phase HPLC shows a single peak and the purity is up to 97%. Its specific activity is up to 1x10 9 IU/mg protein. 20 1.3 Packaging and Inspection After HPLC purification, 2% human serum albumin, 1% sucrose and 1% glucose are added to the rSIFN co. It is then separated and lyophilized into injection sample. When tested under the Wish-VVS 25 inspection system, the result was 4.5x10 8 IU. When tested with aseptic inspection and pyrogen inspection under the standard requirement of China, the results were negative. This result complies with the requirements for IV injection. 30 2. Quality Control 2.1 Biological characteristics (1) When using LB+M9 to cultivate bacteria, the characteristics should match with the typical 35 characteristics of E-coli bacteria. No other bacteria were detected. -41- (2) When smeared for Gram staining and inspected under a microscope, it is bacteria-negative. (3) Reaction to antibiotics is the same as those original bacteria. 5 (4) Electron microscope inspection shows typical characteristics of E-coli bacteria. No mycoplasma, virus spore or other micro pollutes was detected. (5) Biochemical reaction test shows 10 characteristics of E-coli bacteria. 2.2 Quality control pf interferon expression (1) Interferon expression (cultivated in an agitating platform) matches the amount of expression in original input bacteria. 15 (2) When tested with anti-interferon serum, a reaction is shown. (3) Plasmid inspection: Restriction digest matched with the original plasmid. 2.3 Bacteria strain product 20 Bacteria strain product denotes the specimen from the original bacteria strain that was produced from the procedures shown in 1.2. The bacteria strain product should be inspected as follows to make sure there is no derivation: 25 Use LB to plate 2-3 pieces and cultivate. Separate and take 5-10 bacteria groups for the test of interferon expression. Repeat the test at least two (2) times. Only use the one which shows the highest % to be the bacteria strain 30 product. 2.4 Innoculum The innoculum denotes the chosen bacter* strain product after fermentation. The amount, cultivation time and most appropriate OD value of 35 innoculum can be decided according to bacteria strain. An anti-polluted bacteria procedure should apply for whatever innoculum would be -42produced. 2.5 Growing of bacteria strain Growing of bacteria strain would be done in a Bacteria Free room environment where no more than 5 one bacterium is growing in the same room. Same culturing medium will be used for both bacteria strain and innoculum. The one used in rSIFN-co is LB. 2.6 Fermentation 10 (1) Fermentation only takes place in a clean fermentation room with a single bacteria fermentation environment. (2) Cleaning of fermentation container and tube is done twice, before and after the 15 insertion of culturing medium. Then, the container should be frozen to reach the appropriate temperature for innoculum. (3) Avoid using antibiotic which might affect cell growth in the culturing medium. 20 (4) Fermentation parameters like temperature, pH value, dissolved oxygen and time required could be varied according to different types of bacterial strains. 2.7 Bacteria collection 25 (1) Centrifuge the bacteria solution to collect bacteria or use another method. All apparatus should be cleaned before and after the operation. The waste solution should be drained after the cleaning procedure. 30 (2) The bacteria should be kept under 4-8 0 C if they are going to be split within 24 hours. Otherwise, they should be kept under -30 0 C. Those are kept under such conditions can be used within 6 months. 35 2.8 Bacteria cell lysis -43- (1) Use appropriate buffer solution to balance the bacteria strain. Cell lysis can be done by physical, chemical or biological methods. Use centrifuge to precipitate the bacteria 5 and apply cleaning solutions. (2) If the chemical method is used to split cells, no solutions harmful to human beings should be used. 2.9 Purification 10 (1) Purification will get rid of most of the non-interferon contents. In the process of purification, no toxic materials should be found if extra elements are added. (2) If using antibody affinity chromatography 15 for purification, there should be an indication of the source and degree of purity. Also, inspection of small quality IgG should be performed. (3) During the process of purification, 20 =clearance of pyrogen is critical. All apparatus should be checked to eliminate this interference. (4) The highly concentrated interferon is known as "intermediate product". After inspection 25 and tests, add albumin to raise the concentration to 2% which is now known as "albumin intermediate product". After examination and tests, it should be kept at -30 0 C and never thawed before use. This 30 product should be used within 6 months. (5) The albumin that is used in this process should also fulfill tests and requirements such as: negativity under RBSAG inspection and an indication of the ratio among 35 monomer, dimer and polymer. 2.10 Production into tube product -44- (1) Filtration: Use 0.22 p1 membrane to filter the bacteria. The product should be handled. with aseptic techniques. Samples should be taken to test the value of the interferon. 5 (2) Dilution: Dilute the albumin intermediate product with 2% diluent. No preservative should be added. The product can be lyophilized after the aseptic inspection and pyrogen inspection. 10 2.11 Lyophilization The lyophilization should not affect the activity of interferon, and the water content of said lyophilite will be maintained. 2.12 Inspection 15 There are two types of rSIFN-co made. One is for injection and the other for topical use. The specifications for the two are different. There are intermediate products and final products for each type. In the injection type, ,intermediate 20 products include purified interferon, albumin intermediate product, and bacteria free albumin intermediate product. Final product from the injection type will denote only lyophilized product. The intermediate product in the topical 25 type denotes only purified interferon. The final product from the topical type denotes only separated packed liquid formed lyophilized products. 2.13 Packaging 30 There is different packaging for the injection type and the topical type. 2.14 Storage The product should be kept at 4 0 C. The purification solution should not be stored in a 35 frozen state. 2.15 Expiration -45- The expiration period is two (2) years after the lyophilization procedure for lyophilized products. The expiration period is 6 months after individual packing for liquidated products. 5 EXAMPLE 4 rSIFN-co inhibits HBV-DNA duplication and secretion of HBsAg and HBeAg. 10 Materials Solvent and Dispensing Method: Add lml saline into each vial, dissolve, and mix with MEM culture medium at different concentrations.

EXAMPLE 6 Acute Toxicity of rSIFN-co 25 Treat mice with large dose (150pg/kg, equal to 1000 times -57of the normal dose per kilo used in treatment of adult patients) of rSIFN-co at one time by intramuscular injection. Then observe and record their deaths and toxic reactions. Results show that: 24 hours after injection, no 5 abnormal reaction had been recorded. The organs of the animals which had been selected to be killed also had no signs of abnormal changes. Those remaining mice were all kept alive and were normal after two weeks. The weights of mice in the experimental group and control group all 10 increased, and the ratio of increase showed no obvious difference between the two groups (P>0.05) according to their weights on the fourteenth day. No abnormal changes were seen from the main organs of those mice after two weeks. 15 1. Experimental material 1.1 Animals 40 healthy adult mice, weighing 18-22g, half male and half female, qualified by Sichuan experiment animal control 20 center. 1.2 Medicines rSIFN-co (Provided by Sichuan Huiyang Life-engineering Ltd.) sterilized solution, 0.15 mg/ml, Lot: 981201 rSIFN-co was administered i.m. in saline. 25 2. Method Separate the 40 mice into two groups randomly, one for experimental medicine, another for control. Inject medicines or saline at the same ratio (0.1 mi/10 g) 30 through muscle to each mouse according to which group they belong. (150 pg/kg of rSIFN-co for experimental group; and saline for control group). After injection, observe and -58record acute toxicity shown in mice. Kill half of the mice (male and female each half) to check whether there were any abnormal pathologic changes in their main organs, such as heart, spleen, liver, lung, kidney, adrenal gland, 5 stomach, duodenum, etc. after 24 hours. Those that remain are kept and observed until the fourteenth day. Weigh all mice, kill them, and then observe the appearance of the organs listed above to see if there are any abnormalities. Take pathological tissue and examine it, using the 10 examination to assess the difference in weight increases in the two groups. 3. Results Results show that there was no acute toxicity seen after 15 all mice were treated with i.m. rSIFN-co with 150 pg/kg at a time, equal to 1000 times the normal dose per kilo used in treatment of adult patients. In the 14 days after injection, all mice lived well. They ate, drank, exercised, and excreted normally and showed normal hair conditions. 20 None of them died. The observation of the main organs of the randomly selected mice shows no abnormal changes 24 hours after injection. 14 days after injection, all remaining mice were killed. Autopsies also showed no changes. The weights of mice in the two groups all 25 increased, but no obvious difference was shown when accessed with statistic method (p > 0.05). See Table 6.1: Table 6.1 Influence to weights of mice after injection of rSIFN-co Group Dose Animal Weights Weights Increased before after value of injection injection weights (g) (g) (g) Control 0 20 19.8 t 30.8 ± 11.0 1 1 __ 1_11.7 2.8 2.9 rSIFN-co 150 20 19.4 ± 32.1 ± 12.7 ± -59- 1.7 3.3 4.3 4. Conclusion Under conditions of this experiment, there were no toxic reactions in all mice after injection of rSIFN-co with 150 5 pg/kg. The conclusion can be reached that the maximum tolerable dose of i.m. in mice is 150 pg/kg, which is equal to 1000 times the normal dose per kilo used in treatment of adult patients. 10 EXAMPLE 7 The clinic effects of recombinant super-compound interferon (rSIFN-co) The recombinant super-compound interferon (rSIFN-co) is an 15 invention for viral disease therapy, especially for hepatitis. Meanwhile, it can inhibit the activity of EB viruses, VSV, Herpes simplex viruses, cornaviruses, measles viruses, et al. Using Wish cells /VSV system as the assay for anti-virus activity, the results showed that: the other 20 rIFN, was 0.9x10 8 IU/mg, Intron A was 2.0x10 8 IU/mg and rSIFN-co was 9x10 8 IU/mg. The anti-viral activity of rSIFN co is much higher than those of the former two. Under the permission of the State Food and Drug 25 Administration (SFDA), People's Republic of China, the clinical trials have taken place in West China Hospital, Sichuan University, the Second Hospital of Chongqing Medical University, the First Hospital of School of Medical, Zhejiang University since the February 2003. The 30 clinical treatment which focuses on hepatitis -B is conducted under the guidance of the mutilcenter, double -60blind random test. IFN-alb was used as control, and the primary results showed the following: The effect of rSIFN-co compared with IFN-alb in the 5 treatment of chronic active hepatitis B 1. Standard of patients selection: Standards 1-4 are effective for both treatment with rSIFN-co (9jig) and IFN alb (5MU, 50jig), and Standard 1-5 are for rSIFN-co (15gg) treatment. 10 1). Age: 18-65 2).

The total cases were 13. After 12 weeks treatment, 7 of 13 (53.85%) were effective. 3 of 13 (23.08%) HBeAg transferred to negative; 7 of 13(53.85%) HBV-DNA transferred to negative; 11 of 13 (84.62%) heptal functions recovered to 10 normal. 4. The side effects of rSIFN-co compared with IFN-alb in the treatment The side effects of IFN include fever, nausea, myalgia, 15 anorexia, hair loss, leucopenia and thrombocytopenia, etc. The maximum dose of IFN-alb is 5MIU per time; the routine dose is 3 MIU. When taken the routine dose, 90% patients have I- II degree (WHO standard) side effects. They had fever lower than 380C, nausea, myalgia, anorexia, etc. When 20 taken at maximum dose, the rate of side effects did not rise obviously, but were more serious. The maximum dose of rSIFN co is 24jig, subcutaneous injection, every one day for 3 months. The routine dose is 9gg. When routine doses were used, less than 50% of patients had I-II degree (WHO 25 standard) side effects, including fever below 38cC, nausea, myalgia, anorexia, leucopenia and slight thrombocytopenia. With maximum dosage, about 50% patients suffered from leucopenia and thrombocytopenia after using rSIFN-co one month, but those side effects disappeared after stopping 30 treatment for one week. It is safe for continued use. -62- The observations of rSIFN-co treat hepatitis C 1.

Treatment of HBV-infected hepatocytes with interferons leads to inhibition of HBV gene expression. The aim 10 of the present study was to characterize the effects of different. interferons on HBV regulated transcription. Using transient transfection of human hepatoma cells with reporter plasmids containing the firefly luciferase gene under the control of HBV-Enhancer EnH I, Enh II and core promoter, 15 Applicant studied the biological activities of three different interferons on transcription. Materials and Methods 20 1. Interfercins: IFN-con1 (Infeigen*, IFN-Hu'i-Yaic (rSIFN-co) and IFN-beta lb. 2. Reporter plasmid: The DNA fragments containing HBV-Enhancer EnH I, Enh II and core promoter were prepared using PCR and blunt-end cloned into the Smal I site of the promoter- and enhancer-less firefly luciferase reporter plasmid pGL3-Basic (Promega, WI, USA) . The resulting reporter plasmid was named as pGL3-HBV-Luc. 3. Cell Culture and DNA transfection: HepG2 cells were cultured in DMEM medium supplemented with 10% FBS and 100 U/ml 30 penicillin and 100 ug/ml streptomycin. The cells were kept in 30 0 C, 5% C02 incubator. The cells were transfected with pGL3 HBV-Luc reporter plasmid using Boehringer's Lipofectin transfection kit. After 18 hours, the medium - 75 containing transfection reagents was removed and fresh medium was added with or without interferons. The cells were kept in culture for another 48. hours. 4. Luciferase Assay: Forty-eight hours after addition of 5 interferon, the cells were harvested and cell lysis were prepared. The protein concentration of cell lysates were measured using Bio-Rad Protein Assay kit. The luciferase activity was measured using Promega's Luciferase Reporter Assay Systems according td the instructions of manufacturer. 10 RESULTS Expression of Luciferase Activity in Different Interferon Treated Cell Lysates 15 No treatment IFN-conl IFN-Hui-Yang IFN-beta lb 100 48+8 29+6 64+10 20 This result shows that rSIFN-co inhibits most effectively on the expression of HBV gene expression. Example 11: SIDE EFFECTS AND CHANGES IN BODY TEMPERATURE WHEN USING rSIFN 25 co There are usually more side effects to using interferon.
