Abstract

The present invention relates to the use of at least one compound of the formula (I) or (II), in which Ri is H and n is an integer from 2 to 10, in the preparation of a drug for treating diseases from the group comprising tumour, cancer, viral disease, bacterial disease, fungal disease, immune system disease, auto-immune disease or disease associated with a Pimmunostimulation deficiency in human beings and warm-blood animals. The invention also relates to new products having a mannose or mannitol termination as well as a method for preparing the same.

Description

The present invention describes the use of modified oligo-β-(1,3)-glucans of formula (I) or (II) below for the preparation of useful drugs in immunostimulation-based therapies.
Glucans, which are natural products, have been extensively studied and the immunostimulating properties of some glucans are known.
The Applicant has shown, in particular in WO03/045414, that Laminarine, a polysaccharide extracted from the brown algae Laminaria digitata, has immunostimulatory activities. Laminarine is a low molecular weight polysaccharide consisting of a linear β-(1,3)-glucan main chain of 20 to 30 glucose units weakly branched at position 6, which has either a glucose (G chain) or a mannitol (M chain) entity at the terminal end.
Although the immunostimulatory activity of Laminarine has been recognised, a major disadvantage of its use for therapeutic purposes is its natural origin, as the composition of Laminarine is not constant and depends on the place of collection, the time of collection, etc.
There is therefore a real need for synthetic products with the therapeutic properties of Laminarine.
The present inventors have focused in particular on the M-group oligosaccharides present in Laminarine. In the literature it is mentioned that these oligosaccharides have a β-configuration bond between carbon 1 of the terminal glucan and a primary carbon of the mannitol residue, and can be represented as follows:
They have sought to synthesize these molecules in such a way as to make available, particularly to the pharmaceutical industry, molecules with a complete characterization and a completely elucidated structure, thus avoiding the difficulties inherent in the use of natural products as pharmaceutical products.
Unexpectedly and surprisingly, the present inventors found that the oligosaccharides of formula (I) or (II) below, which themselves have a β-link between carbon 1 of the terminal glucose and a secondary carbon of the terminal mannose or mannitol, exhibited immunostimulatory activities.
The invention therefore describes the use of at least one modified oligo-β- ((1,3) -glucan of formula (I) or (II) - What? where R1 is H or OH and n is an integer from 2 to 10, preferably from 2 to 7, and more preferably still 3, 4 or 5, for the preparation of a composition for the treatment of diseases selected from the group consisting of tumour, cancer, viral disease, bacterial disease, fungal disease, immune system disease, autoimmune disease or disease related to immunostimulation deficiency in humans and warm-blooded animals. The action of the compounds of formula (I) or (II) is related to the presence of specific receptors of these compounds on the surface of macrophages and more generally of the different populations of leukocytes. This activity is attributed to the stimulation of the body's immune-compressing cells and is measured by: The activation of NK cells, T lymphocytes, and nuclear factor κB(NF-κB; phagocytic activity; the secretion of cytokines such as interleukins (IL), TNF-α, or interferon γ; the production of reactive oxidant species such as the superoxide anion or hydrogen peroxide.
Advantageously, when in the compound of formula (II), R1 represents OH, the terminal group is a mannitol.
The mechanisms of interaction of many glucans have been widely described, but have shown often conflicting results, making it impossible to predict which glucan is the best immunomodulator.
The present invention relates to some of the derivatives of formula (I) and (II) above which are novel compounds. These new compounds are oligo-β- ((1,3) -glucan-(1,3) -mannose and oligo-β-(1,3) -glucan-(1,3) -mannitol and their deoxy derivatives in position 4, which have the general formula (I') or the general formula (II') respectively: wherein R1 represents H or OH and n is an integer from 2 to 10, preferably from 2 to 7, and more preferably still equal to 3, 4 or 5. In particular, such compounds are the following: The following shall be indicated in the column 'D' of the column 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the following entries: 'D' for the entries: 'D' for the entries: 'D' for the entries: 'D' and 'D' for the following entries: 'D' for the following entries: 'D' for the entries: 'D' and 'D' for the following entries: 'D' for the following entries: 'D' and 'D' for the following entries: 'D' and 'D' for the following entries: 'D' and 'D' for the following entries: 'D' and 'D' for the following entries 'D' and 'D' for the following entries 'D' and 'D' for the following entries 'D' entries 'D' and 'D' for the following entries 'D' and 'D' for the following entries 'D' entries 'D
These new compounds are useful as pharmaceutical compounds.
The invention therefore also concerns medicinal products containing these new compounds with at least one excipient chosen according to the chosen mode of administration and dosage.
These medicines may be medicines intended for oral, intravenous or intra-peritoneal administration.
The doses of compounds of formula (I'), (II') are dependent on the disease to be treated and the method of administration chosen.
Useful oral medications are tablets, granules, syrup, capsules, and gel.
These medicinal products may also include at least one chemotherapeutic agent selected from the group consisting of cisplatin, vinblastin, paclitaxel, taxol and its derivatives, monoclonal antibodies such as Rituximab and Cituximab.
In particular, these compounds are useful as immunomodulatory agents.
Another subject matter of the invention relates to the use of at least one compound of formula (I') or (II') for the treatment of a disease selected from the group consisting of tumor, cancer, viral disease, bacterial disease, fungal disease, immune system disease, autoimmune disease or disease related to immunostimulation deficiency, in warm-blooded animals and humans.
These compounds have an original structure since the glucanic part is connected to the mannitol residue by one of these secondary hydroxyls via a β-configuration bond. The presence of molecules of formulae (I') and (II') in which R1 represents -OH has been shown in Laminaria digita.
The chemical preparation of new compounds of formula (I') or (II') is based mainly on the epimerisation of the terminal reducing entity of the D-glucose type into a D-mannose type residue. This involves the singularisation of the reducing entity in relation to the other glucose units of the oligosaccharide and the singularisation of the hydroxyl 2 of this entity in relation to the other functions of the reducing unit. Two different synthesis routes are envisaged, an iterative synthesis and a synthesis by epimerisation of the terminal entity.
According to the first embodiment, the process of preparation of the new compounds involves a reaction between a glycosyl donor of formula (D) below and a glycosyl acceptor of formula (A) below: - What? in which m is an integer from 1 to 9, preferably 1 to 6, and preferably still equal to 2, 3 or 4; p is an integer from 0 to 9, preferably 0 to 6, and preferably still equal to 2, 3 or 4;R represents an alkyl such as ethyl, methyl, propyl or butyl, or an aryl such as phenyl or tolyl;R2 represents an allyl,Methylnaphthyl, benzyl, paramethoxybenzyl, halogen acetyl (chloroacetyl, bromoacetyl, iodoacetyl) ;R3 and R4 on the one hand and R3' and R4' on the other hand together constitute an ethyl radical, isopropyldyl, hexafluoroisopropyldyl, cyclopentyldyl, cyclohexylidyl, cycloheptyldyl, butyldyl, 1-tertiobutylethyl, benzyl, methoxybenzyl, 1-phenylbenzyl or chloroacetyl R3, R4, R3' and R4' each representing a trivalyl group independently of the other, such as trivalylbenzyl, chlorylbenzyl, benzylvulb, nitrobutylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylbenzyl, trivalylben
In this application the following abbreviations are used: The following is a list of the substances which are used in the preparation of the product:
The compound of formula (A) is advantageously - What? The compound of formula (D) is advantageously
This step of the process can be included in an iterative synthesis which differs from that described in FR2804684 by the necessary use of a first acceptor with at position 2 an orthogonal protective grouping of all other groups present on the synthesized oligomers after chain elongation, which makes regioselective epimerization possible.
This iterative synthesis can be described according to the reaction pattern (reaction pattern 1) as given below:
The reaction pattern 1 above consists of: the preparation [a'] from a compound 1 as obtained in FR2804694, of a compound 2 whose -SEt group has been replaced by a -OBn group; the substitution [a] at position 2 of -OBz by -OR5, R5 being preferably a levuloyl, and the selective deprotection [b] of the hydroxyl at position 3; the reaction between donor 1 and acceptor 4 [c], or glycosylation; possibly the selective deprotection [d] at position 3 of the hydroxyl and glycosylation between compound 1 and NaOH group 6, these two groups being repeatable until a desired number of glucose units is obtained; [OH] is the preferred levuloyl group; [OH] is the preferred periodic deprotection group; [OH] is the preferred method of de-protection; [OH] is the preferred method of de-protection; [OH] is the preferred method of de-protection; [OH] is the advantage of reducing the acetone group; [OH] is the advantage of reducing the acetone group; [OH] is the advantage of reducing the acetone group; [OH] is the advantage of reducing the acetone group; [OH] is the advantage of reducing the acetone group; [OH] is the advantage of reducing the acetone group; [OH] is the advantage of reducing the acetone; [OH] is the advantage of reducing the acetone; [OH] is the advantage of reducing the acetone; [OH] is the advantage of reducing the acetone; [OH] is the advantage of acetone; [OH] is the advantage of reducing the acetone; [OH2 is the advantage of acetone; [OH] is the advantage of acetone; [OH] is the advantage of acetone; [OH] is the advantage of acetone is the advantage of acetone; [OH] is the advantage of acetone; [OH] is the advantage of acetone is the advantage of acetone; [OH] is the advantage of acetone is the advantage of acetone is the advantage of acetone; [OH] is the advantage of acetone is the advantage of acetone; [OH] is the advantage of acetone is the advantage of acetone;
It is also possible to consider synthesis by implementing a more convergent reaction pattern, as defined below (reaction pattern 2). In this reaction scheme, the donor D is a disaccharide, or higher oligosaccharide, which is reacted with an acceptor A which is also a disaccharide or higher oligosaccharide: tri-, tetra-, penta-, as obtained as compound 6 according to reaction scheme 1.
In this second reaction scheme, preferably R' is Ac, Bz or pivaloyl and R5 is Lev.

A second method of production involves the preparation of new compounds by an epimeration step at position 2 of the terminal chain, which also produces deoxygenated compounds at position 4.
The reaction diagram 3 below illustrates this method of implementation: - What?
In reaction diagram 3, R7 is an ester, notably acetyl, benzoyl, pivaloyl, preferably Bz, and R8, a group orthogonal to all other protective groups, may be Bn, NAP, p-methoxybenzyl, p-methoxyphenyl, allyl, and preferably Bn, X is preferably a bromine.
This third reaction pattern consists of: the reaction [A] protects all OH groups, preferably the protective group is Bz and the reaction is then conducted with BzCl in pyridine,selective halogenation [B],preferably bromination by HBr in AcOH;elimination [C],preferably with DBU diazabicylcoundesen;addition [D],preferably with N-bromosuccinimide in MeOH;substitution in an anomalous position and elimination of the protected hydroxy group in position 4 of the terminal entity [E],preferably with Ph3PO or a Lewis acid such as silver triphlate in benzylic alcohol or any other alcohol including naphthal ethanol,protective group p-hydroxy alcohol,p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxybenzylic p-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy-hydroxy

EXAMPLE 8: Effect of LAM5, LAM7, A2 and A0 on phagocytosis of peripheral blood cells:
In a group of Balb/c mice (Jackson laboratory, Bar Harbor, ME, USA) one or both of a control, LAM5, LAM7, A0 or A2, was injected peritoneally. 24 hours after the injection the mice were killed. Peripheral blood from the orbital plexus was collected in heparin (5 IU/ml) (Sigma).
After counting, a HEMA particle phagocytosis assay (synthetic microspheres prepared from 2-hydroxyethyl methacrylate copolymer) was performed as described in: Rembaum et al. 1976, Vetvicka et al. 1982, Bilej et al. 1989, 1989.
At the end of incubation, the cell suspension was rubbed on microscope lamellae and the smears were evaluated under optical microscope after Giemsa staining.
Cells containing at least three particles were considered positive.
The mean results are shown graphically in Figure 1. They clearly show that both A0 and A2 strongly stimulate phagocytosis in monocytes and granulocytes.
EXAMPLE 9: Effect of oligosaccharides on phagocytosis of cells from the peritoneal cavity:
A group of Balb/c mice (Jackson laboratory, Bar Harbor, ME, USA) were injected intraperi-torneally with either a control, LAM7, LAM5, A0 or A2.
After 24 hours, the mice were sacrificed, the peritoneal cells were collected in a Hanks (Sigma) medium.
After cell counts in a haemocytometer, the peritoneal cells were diluted tolx107 in a 1640 RPMI medium (Sigma) with 5% foetal calf serum (Hyclone, Logan, UT, USA). 2x106 cells in 0.2 mil of medium RPMI 1640 with 5% foetal calf serum were mixed with the same volume of HEMA particles (5x108/ml).
The suspension was incubated for 60 minutes at 37°C with occasional moderate agitation, the incubation was completed by centrifugation (150 g for 5 minutes) and the ball was resuspended.
Macrophages with ingested particles were counted under an optical microscope in Accustain-colored smears (modified Wright dye, Sigma).
Cells containing at least six particles were considered positive.
The mean results are shown graphically in Figure 2.They show that both A0 and A2 strongly stimulate phagocytosis in both monocytes and granulocytes of peritoneal macrophages.
