Abstract: In order to provide the anti-retrovirus active compound with low anti-coagulant action and low cytotoxicity, compounds comprising glycoside or the salt thereof wherein lipid is linked to position 2 of sialic acid having all hydroxyl groups at positions 4, 7, 8 and 9 completely sulfated, or KDN (2-keto-3-deoxy-D-glycero-2-nononic acid) having all hydroxyl groups at positions 4, 5, 7, 8 and 9 completely sulfated are provided.

Description: BACKGROUND OF THE INVENTION Field of the Invention This invention relates to a novel compound with the anti-viral activity and a drug and anti-viral agent containing said compound as the effective ingredient, more specifically relates to a medicine and anti-HIV active compound comprising the sulfated nonulonic acid. Description of the Related Arts Azidothymidine (AZT) and dideoxy inosine (DDI) have been used as the AIDS remedy. These agents are to inhibit the reverse transcriptase of HIV, bringing about apothanasic effect to patients, while posing problems that the chronic administration of AZT causes myelopathy and that the DDI administration results in side reactions such as acute pancreatitis and peripheral neuropathy. Furthermore, the use of either drug eventually results in the generation of virus resistant to these drugs. Recently, the sulfated polysaccharide has been expected as a promising AIDS remedy. It is well known that polysulfated compounds such as dextransulfate (I) (Japanese Patent Laid-Open Publication No. Sho63-45233) , polyvinyl alcohol sulfate (II) (Antimicrob. Agents Chemother 34, 134-138 (1990)), oligosaccharide sulfate (Japanese Patent Laid-Open Publication No. Hei2-304025) inhibit the proliferation of HIV. These compounds are produced simply by binding the sulfate group to polysaccharides, oligosaccharides or organic polymeric molecules. In addition, the sulfated modified cyclodextrin (III) is cyclodextrin to which lipid-soluble groups such as aryl-, alkyl-groups are introduced, and also has the proliferation inhibiting activity against retroviruses, HIV in particular (Japanese Patent Laid-Open Publication No Hei4-136001) In addition, as a virucide comprising the sulfated polysaccharide as the active ingredient is disclosed the one using an acyl derivative of a sulfated oligosaccharide glycoside (Japanese Patent Laid-Open Publication No. Hei6-256373) . At first, it was conceived that the virucidic activity of sulfated polysaccharides was due to their reverse transcriptase inhibiting activities, and now it is thought to be due to the interaction between the sulfated polysaccharide and the coat protein gp120 of HIV. However, since sulfated polysaccharides generally have the inhibitory activity for the blood coagulation system (anticoagulant activity), they have not been accepted as the suitable medicine. JP-A-3 170 020 discloses an anti-HIV agent comprising sulfated sugar-ceramide compounds. EP-A-0 587 374 discloses sulfated sterol glycosides and their use against viral infections.

BEST MODE FOR CARRYING OUT THE INVENTION Definition of the terms As used in this specification, by the term "nonuloic acid" is meant the same nonuloic acid as used generally, an acidic carbohydrate having a carboxyl group at its position 1 and 9 carbon atoms. Accordingly, "nonuloic acid derivatives" used in this specification include neuraminic acid (5-amino-3,5-dideoxy-D-glycero-D-galactononuloic acid) and neuraminic acid derivatives. Since the later-described "sialic acid" is an acyl derivative of neuraminic acid, it is also included in "nonuloic acid derivatives". By "KDN" used in this specification is meant 2-keto-3-deoxy-D-glycero-2-nononic acid. And, by "sialic acid used in this specification is meant the generic name for a series of derivatives of substances having the neuraminic acid as the basic structure (Yasuo Inoue, Seitai Bunsi no Kagaku, Tositu no Kagaku (Chemistry of Biomolecules 1, Chemistry of Carbohydrates), p80-81, Baifukan), and acyl derivatives, more specifically, such as N-acetylneuramic acid and N-glycolylneuramic acid are also included therein. By "forked two chains" [for example, (6),] is meant a structure constructed with two chains having more than 7 skeleton-forming atoms. Accordingly, alkyl groups according to claim 7 (7), wherein the total number of their skeleton-forming atoms is 1 to 4, are not included in "chain" constructing "forked two chains". By "skeleton-forming atoms" is meant atoms constructing the skeleton of the chain, including carbon atom, oxygen atom, nitrogen atom, sulfur atom, etc. However, monovalent atom, such as hydrogen atom, is not included in the "skeleton-forming atoms", because it cannot construct the skeleton portion of the chain. By "salt" is meant the sodium and potassium salts which are required to neutralize the intramolecular carboxylic acid and sulfonic acid, to which cations bind so as not to decrease the biological activity. As to the cations bound to said acids, any cations which do not lower the biological activity of the compounds related to the present invention may be used. Sugars In principle, the compound related to this invention according to claim 1 is a glycosidic compound and the salt thereof comprising a sugar-lipid with said lipid bound to the anomeric carbon of a monulonic acid moiety by a glycosidic linkage or to the carbon at position 1 of a monulonic acid moiety by an amide or ester linkage, wherein hydroxyl groups of said monulonic acid moiety are all sulfated, having an excellent anti-retroviral activity [the above-described (1), claim 1]. Although there have been hitherto found the sulfated sugars with the anti-retroviral activity, the glycoside comprising a sugar-lipid with sulfate group introduced according to claim 1 and having the anti-retroviral activity has not been discovered. In this respect, this invention is valuable in finding that a glycoside comprising a sugar-lipid with the sulfate groups fully (100%) introduced or the derivative thereof according to claim 1 has an excellent anti-viral activity. When the sugar moiety of said glycoside is sialic acid or KDN, the glycoside not only has the strong anti-viral activity, but also lower cytotoxicity, and can preferably achieve the main purpose as medicine [the above-described (2) to (22), (26) to (28), and claims 2 to 22 and claims 26 to 28]. And, in this case, the hydroxyl groups of the sugar moiety of the compound related to the present invention to be all sulfated to form the wholly sulfated nonulonic acid [the above-described (1), and claim 1] are at positions 4, 7, 8 and 9 when nonulonic acid is N-acetylneuramic acid, and the glycolyl hydroxyl group at position 5, in addition to the hydroxyl groups at the positions 4, 7, 8 and 9. In the case wherein nonulonic acid is KDN, all the hydroxyl groups at positions 4, 5, 7, 8 and 9 are sulfated. The bond between the monosaccharide moiety and lipid moiety of the compound related to the present invention can be of any type. Accordingly, the bond between the monosaccharide and lipid may be not only the O-glycosidic linkage but also S-glycosidic linkage. Furthermore, as the sugar moiety of the compound related to the present invention is nonuloic acid, the amide linkage and ester linkage can be formed using the carboxyl group at position 1, in addition to a glycosidic linkage with the carbon atom at position 2. The bond between monosaccharide and lipid in the compound related to the present invention can be such amide linkage and ester linkage. Therefore, although, by "glycoside" is generally meant a compound wherein the monosaccharide and lipid moieties are linked by a glycosidic linkage, by "glycoside" in this specification is meant a compound wherein the monosacchharide and lipid are bonded not only in a glycosidic linkage but also in amide and ester linkages. Accordingly, not only compounds having a glycosidic linkage at position 2 of nonulonic acid but also those having an amide linkage or ester linkage at position 1 of nonulonic acid are also in the scope of "glycoside" of the present invention. However, in consideration of the overall manufacturing easiness and biological activity of these compounds, glycosides with the O-glycosidic, S-glycosidic, and amide linkages are preferred. Lipids By "lipid" in the compound related to this invention is meant the lipid in a broad sense including steroid, carotinoid, terpenoid, etc., and conceptionally even the compound such as cholesterol. However, the compound related to this invention is preferably a linear lipid, which further preferably has the branched chain structure [the above-described (4), and claim 4]. The branch can be two-forked or three-forked, located at position 2 of the main chain of the lipid moiety. As a result, the lipid is preferably two-forked at the β position (β position with respect to the sugar moiety) of said lipid moiety [the above-described (5) and (6), and claims 5 and 6]. Furthermore, this branching site may have alkyl group with the skeleton-forming atoms 1 to 4 [the above-described (7), and claim 7]. "Alkyl group with the skeleton-forming atoms 1 to 4" herein cited includes, for example, methyl group, ethyl group, propyl group, etc. The above-described two-forked chain can be a hydrocarbon chain, which can include heteroatoms such as oxygen, nitrogen, sulfur, etc. Furthermore, regardless of the species of component atoms, the total number of the skeleton-forming atoms of lipid is preferably 22 to 60 [the above-described (8), and claim 8]. In addition, the above-described two-forked chains can have unsaturated bond between carbon atoms, respectively [the above-described (9), and claim 9]. Also, although the above-described two-forked chain can be further branched, they are preferably linear [the above-described (10), and claim 10]. In the case where the above-described two-forked chain contains heteroatoms as the component atom, each branched chain preferably contains an ester bond or ether bond [the above-described (11), and claim 11], furthermore, said ester bond or ether bond is preferably localized at position 1 or 2 of said branched chain [the above-described (12), and claim 12]. Herein, when the ester bond or ether bond is present at position 1 of the branched chain, the compound related to this invention will become the sulfated derivative of sialoglycerolipid with the excellent anti-reteroviral activity (In this connection, in the case of ether bond present, said compound will be an alkyl glycerol wherein a long-chain alcohol is linked to the glycerol residue, and in the case of ester bond present, said compound will be amyl glycerol.). Furthermore, in the case where ester bond or ether bond is located at position 2 of the branched chain, the glycerol residue in the glycerol area is suitably modified to become pseud-glycerol. As to the length of branched chains, the number of skeleton-forming atoms is preferably 10 to 28 [the above-described (13), and claim 13], more preferably 18 to 26 [the above-described (14), and claim 14], most preferably 24 [the above-described (15), and claim 15]. In addition, forked-chains can be of different lengths, but preferably of the same length [the above-described (16, and claim 16], most preferably of the same structure comprised of the same component atoms [the above-described (17), and claim 17] Method of Administration When compounds related to the present invention are used as therapeutics, they are administered singly or in combination with pharmaceutically acceptable medical carriers, either organic or inorganic and either solid or liquid.

Assessment of growth inhibitory effect on HIV-1 and cytotoxicity Samples of various concentrations (25 µl) are distributed into a 24-well microplate, immediately added with human T cells (H9 cell line, 1.2 x 10 5 /ml) (1 ml), covered, and incubated at 37 °C for 1 h. Then, AIDS virus (HIV-1, IIIb, 100 TCID 50) (25 µl) is added to each well and thoroughly mixed, covered again, and incubated under the CO 2 atmosphere at 37 °C for 3 days. On the fourth day, aliquots (200 µl) of the culture medium from each well are transferred into a fresh microplate. The growth medium (500 µl) is added to each well, and further incubated for 2 days. On the 6th day, aliquots (90 µl) of the culture supernatant are withdrawn, and assayed the amount of p24, a constituent of HIV-1, by ELISA method using the anti-p24 antibody to assess the growth of said virus. Also, using the remaining cell culture suspension (100 µl), viable cells are counted by the MTT method. Experimental values are expressed as the ratios (%) to the negative control value (measured using the solvent to dissolve test compounds as the sample) to represent the anti-HIV activity and cytoxicity. Then, for the unified representation of the anti-HIV activity and cytotoxicity, the concentrations of test compounds at their 50% values are obtained from the activity-concentration curves and the cytotoxicity-concentration, and represented as IC50 and CC50, respectively. Results of the anti-HIV activity assay In the following table are shown the compounds and their structural characteristics having IC50 (µ M) values less than 100 µ M. Carbon number of the functional group (in parentheses) represents that of alkyl group of lipid side-chain beyond the ether linkage, and, particularly, in the case where lipid is alkylglycerol, that of alkyl group of said alkyl glycerol. Example No. IC 50 (µ M) Functional group (carbon number) 5 46.0 Two alkyl chains (10) 6 50.0 Two alkyl chains (10), β -isomer of 5 7 16.0 Two alkyl chains (14) 8 15.0 Two alkyl chains (14) β -isomer of 7 9 3.8 Two alkyl chains (18) 10 30.0 One alkyl chain (18), with a sulfate group as a side chain 11 13.0 One alkyl chain (18), β -isomer of 10 12 0.8 Two alkyl chains (22) 13 1.6 Two alkyl chains (22), β -isomer of 12 14 15.0 Two alkyl chains (14), thioglycoside 17 2.5 Two alkyl chains (20) 20 1.2 Two alkyl chains (24) 24 34.0 Cholesterol 25 100.0 One alkyl chain (18), unsaturated 26 100.0 One alkyl chain (18) 29 1.6 Two alkyl chains (22), branched 32 2.5 Two alkyl chains (20), branched 35 90.0 Aromatic 38 2.5 Two alkyl chains (22), glycero-ester 41 4.0 Two alkyl chains (22), KDN 50 1.1 Two alkyl chains (22), with an ethyl group at the branching point 59 1.4 Two alkyl chains (22), amide linkage These results indicate that, as the lipid bound to nonulonic acid (sialic acid and KDN) via glycosidic linkage are preferred alkyl, carbonyloxy or oxycarbonyl groups. Furthermore, no significant difference observed in the activity of Example 7 (O-glycoside) as compared with that of Example 14 (S-glycoside) indicates that the linkage between carbohydrate and lipid moieties can be either O-glycosidic or S-glycosidic. Also, no difference observed in the activity between Example 29 and Example 59, wherein they differ only in that the former has the O-glycosidic linkage and the latter the amide linkage, leads to the conclusion that the linkage between carbohydrate and lipid can be of any form So far as sulfuric acid derivatives of sialoglycerolipids are concerned, as evidently seen comparing Example 9 (two alkyl chains, each having 18 carbon atoms, IC50: 3.8) and Example 11 (one alkyl chain with 18 carbon atoms, IC50: 13.0), both derivatives, one with single chain, and the other with two chains, have the enough activity for the practical use, but the latter one is generally more active. Therefore, derivatives with two alkyl chains can be more preferable than those with one alkyl chain. Also, as evidently seen comparing Example 38 (two alkyl chains, each having 22 carbon atoms, glyceroester, IC50: 2.5) and Example 12 (two alkyl chains, each having 22 carbon atoms, IC50: 0.8), these compounds have high activity regardless of whether their glycero-lipid moieties are either alkylglycerol or acylglycerol. Therefore, the biological activity is not so much affected by the linkage form between the glycerol skeleton and the long alkyl chain group, but rather mainly dependent on the length of long alkyl chain group. So far as compounds wherein glycerol having two alkyl chains is linked to sugar via glycosidic linkage are concerned, as shown in Table 1, minimum IC50 values are associated mostly with those with carbon atoms of 18 ( Example 9), 20 (Example 17), 22 (Example 12) and 24 (Example 20). Therefore, in the case where the sulfate derivatives of sialoglycerolipids related to this invention are either alkyl glycerol or acyl glycerol, number of carbon atoms of alkyl groups linked to the glycerol moiety is thought to be preferably 18 ∼ 24. Since the biological activity depends mainly on the length of long-chain alkyl group linked to the glycerol skeleton, said long chain alkyl group can be saturated or unsaturated, also branched. In the case of alkyl glycerol with 24 carbon atoms as in Example 20, the "number of skeleton-forming atoms" per one side chain amounts to 25. This is because the "number of skeleton-forming atoms" includes the oxygen atom related to the ether linkage, in addition to carbon atoms of alkyl group. Furthermore, in the case of pseudo-glycerol as in Example 29 and Example 32, since the carbon atom of methylene group between the carbon atom at the β position of the main chain of glycerol moiety and the oxygen atom of the ether linkage is also included in the "number of skeleton-forming atoms", that number becomes 24 in the case of Example 29, and 22 in the case of Example 32. Also, the glycerol moiety can have a methyl branch, and a methylene group between the main chain of the glycerol moiety and ether linkage or ester linkage (Example 29 and Example 32). Therefore, the glycerol moiety can have a short alkyl chain such as methyl, ethyl, propyl, butyl groups, etc. at the β carbon atom of its main chain (in this case, however, these groups cannot be called side chain or branched chain because of insufficient length of alkyl groups.), and one to three carbon atoms can be present between the main chain of glycerol moiety and the ether or ester linkage. In comparison of Example 29 with Example 12, two chains extending from the β carbon atom of the main chain of glycerol moiety are of the same length in Example 29, while they are of the different length in Example 12. That is, in Example 29, number of "skeleton-forming atom" per one chain of the two chains extending from the β carbon atom of the main chain of glycerol moiety is the same 24, but different in Example 12, as 23 and 24. Therefore, it can be concluded that, in the case of two chains, number of "skeleton-forming atoms" per one chain, furthermore, number of alkyl chain-forming carbon atoms can be different. In addition, as to Example 29, it is advantageous that the two chains are completely the same having the same component atoms and configuration because for the easy preparation. In the table below are shown CC50s. Example No. CC 50 (µ M) Example No. CC 50 ( µ M) 5 >200 20 >20 6 >200 24 >200 7 >200 25 >200 8 >200 26 >200 9 >200 29 >20 10 >200 32 >200 11 200 35 >20 12 >200 38 >200 13 >200 41 >200 14 >200 50 >200 17 >20 59 >200 These results indicate that compounds related to the present invention are generally low in the cytotoxicity.

At the same time, to the cell control well and virus control wells was added the equal amount of medium. After the supernatant was discarded, the medium (0.5 ml) and the virus stock (0.2 ml) were added to the sample well and virus well, respectively. After incubating again for 1 h, the sample solution (1 ml) diluted with methylcellulose containing FBS was overlayered. To the control well was added only the same amount of the vehicle. Cells were cultured at 36-38 °C under the 5-7% CO 2 atmosphere, and examined for the appearance of plaques under microscope. Monolayer of cells was fixed with 10% formalin, washed with water, stained with 0.8% crystal violet, and dried. Number of plaques counted in the sample well was compared with that in the virus control well, and the decrease in the number of plaques was used to express the antiviral activity. Cytotoxicity assay Of the anti-viral activity assay procedures mentioned above, the virus infection step was omitted from sample wells, and cells were cultured in the presence of samples at various concentrations, and viable cell number was compared with that in the cell control well. Surviving cell number was counted by the tetrazolium method for the microplate assay. 2) Reverse transcriptase assay a) Preparation of host cell and virus Each virus was obtained from ATCC. FIV was cultured with CRFK cells in Eagle's balanced salt medium containing 10% FBS, and the supernatant was used as the virus stock. As FeLV was used ATCC VR-717. b) Preparation of sample Compound related to Example 29 was diluted with the medium to similar concentrations described above c) Assay procedure For each single strain of virus, the assay was performed in the following combinations of conditions Medium control well Culture medium Cell control well Culture medium + cell Cytotoxicity well Culture medium + cell + sample Virus control well Culture medium + cell + virus test well Culture medium + cell + virus + sample Color control well Culture medium + sample After CRFL cells were cultured in monolayer in 96-well microplates, the supernatant was discarded. Then, to the medium control well, the cell control well and the virus control well was added the medium (0.2 ml), and to the cytotoxicity well, the test well and the color control well was added the diluted sample solution at 0.2, 0.1, and 0.2 ml, respectively, and incubated under the 5-7% CO 2 atmosphere at 36-38 °C for 1 h. Then, supernatants of the virus control well and the test well were discarded, and the virus stock (0.1 ml) was added, and incubated further for 1 h. The, after supernatants were removed, and, to the virus control well was added the medium (0.2 ml), and to the test well the same volume of the diluted sample, then the incubation was further continued. Reverse transcriptase assay by ELISA Using supernatants as the sample from the cell control well, the virus control well and the test well, the reverse transcriptase of FIV or FeLV antigen contained therein were quantitated using assay kits from Amersham LIFESCIENCE and Synbiotics, respectively. Anti-viral activity was expressed as that ratio (%) of the value of the test well to that of the virus control well after both values were subtracted with the value of the cell control well, respectively. Cytotoxicity assay Viable cell numbers in the cytotoxicity well and the cell control well were counted by the tetrazolium method for microplate assay similarly as described above, and the cytotoxicity was expressed as the ratio (%) of the cell number of the former to that of the latter Anti-viral activity other than HIV and cytotoxicity Results of anti-viral activity assay are shown in the table below.
