Description

BACKGROUND TO THE INVENTION
The present invention provides a series of novel monosaccharide compounds which are analogs of the known lipid A, and which have been found to have immunoactivating and anti-tumor activities. The invention also provides processes for preparing these novel compounds as well as methods and compositions using them for the treatment, prophylaxis, diagnosis and support of patients suffering from immunodeficiency diseases and disorders and for inhibiting the growth of tumors.
The outermost layer of the cell wall of a gram negative bacterium obtained from species of enteric bacteria, such as Escherichia coli, contains a toxic component (an endotoxin) which is not secreted out of the bacterium. This endotoxin exhibits various biological activities, in addition to its endotoxic activities: for example, it is an immunoadjuvant, activates macrophages, induces mitogenesis, causes pyrogenesis and may cause tumor necrosis; it also enhances the production of antibodies and induces the production of TNF (tumor necrosis factor), both of which have important functions in the immune systems of animals, including human beings. It is, therefore, of considerable interest as a possible precursor of drugs which may be of value in the treatment, prophylaxis, support or diagnosis of diseases and disorders which arise from or result in deficiencies of the immune system in humans and other animals.
It has previously been found that the endotoxin comprises a lipopolysaccharide and that the center of activity of this endotoxicity lies in the moiety now known as "lipid A". It has also been found that the monosaccharides known as "lipid X" and "lipid Y", which are lipid A biosynthesis precursors, may be separated from an E. coli mutant, and that these exhibit similar activities to those of lipid A, although weakly.
Consequently, various derivatives of lipid A monosaccharide, lipid X, lipid Y and the non-reducing sugar part of lipid A have been synthesized and their activities examined �see for example Imoto et al., Tetrahedron Lett., 26, 1545 (1985) or Kiso et al., Carbohydrate Research, 162, 127 (1987)!.
However, since these derivatives are the bacterial endotoxins per se, their use as drugs can still give rise to problems, including the induction of lethal toxicity, exothermic activity, leukopenia and autoimmune diseases. There is, therefore, a need for a compound of this type, which, whilst retaining their desirable activities, lacks the toxicity problems of the naturally occurring compounds.
Several attempts have been made to provide compounds which fulfil these requirements. For example, Lipid X is disclosed in WO 84/04526 as having immunostimulating activity, and a number of saccharide derivatives are disclosed in British Patent No. 2 211 503 and are said to be useful as modulators of antimicrobial resistance, for enhancing immune response, for the prevention of endotoxic shock and for the treatment of malignant tumors and inflammation. However, of the compounds known to date, the most active is thought to be that known as GLA-60, which is disclosed, for example, in J. Carbohydrate Chem., 6(4), 625-638 (1987) and Carbohydrate Research, 162, 127-140 (1987).
We have now discovered a series of saccharide derivatives, which are lipid A monosaccharide analogs and which have activities of the type discussed above which are, at worst, comparable with those of GLA-60, and which are, in some cases, very substantially better than those of GLA-60, and are therefore probably the most active compounds of this type currently known. The compounds of the present invention are distinguished from the prior art compounds by the presence of at least one halogen, and preferably fluorine, atom at one or more of certain specific selected sites in the molecule.

Certain of the compounds of the present invention may contain a carboxy group and can, therefore, form esters, which also form part of the present invention. There is no limitation upon the nature of such esters, provided that, where the resulting compound is to be used for therapeutic purposes, it is pharmaceutically acceptable, which, as is well known in the art, means that the compound does not have reduced activity (or unacceptably reduced activity) or increased toxicity (or unacceptably increased toxicity) as compared with the corresponding compound of formula (I), i.e. the free acid. Where, however, the compound is to be used for non-therapeutic purposes, e.g. as an intermediate in the preparation of other compounds, even this limitation does not apply, and the nature of the ester group may be chosen having regard simply to process criteria.

The compounds of the present invention will contain at least one asymmetric carbon atom in their molecules and may contain several, and can thus form optical isomers having the (R)-configuration or the (S)-configuration. Although these are all represented herein by a single molecular formula, the present invention includes both the individual, isolated isomers and mixtures, including racemates thereof. Where stereospecific synthesis techniques are employed, individual isomers may be prepared directly; on the other hand, if a mixture of isomers is prepared, the individual isomers may be obtained by conventional resolution techniques.
Examples of specific compounds of the invention are given in the following formulae (I-1) to (I-3), in which the substituents are as defined in the corresponding one of Tables 1 to 3, respectively �i.e. Table 1 relates to formula (I-1), Table 2 relates to formula (I-2) and Table 3 relates to formula (I-3)!. ##STR3##

and then, where desired, removing protecting groups and optionally replacing any one or more of the groups represented by any of R.sup.1", R.sup.2', R.sup.3', R.sup.4" and R.sup.5' by any of the groups represented by R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 in the definition of formula (I), above;
and optionally esterifying or salifying the product.
In more detail, the compounds of the present invention may be prepared by the reactions shown in the following Reaction Schemes A to E, depending on the exact compounds which it is desired to prepare. ##STR7##
In the above formulae:
R.sup.2 and R.sup.3 are as defined above;
R.sup.2a and R.sup.3a are the same or different and each represents any of the groups defined above for R.sup.2 and R.sup.3 but in which any reactive group is optionally protected;
R.sup.6 represents an amino-protecting group, such as the aliphatic acyl groups exemplified above, the aromatic acyl groups exemplified above, the alkoxycarbonyl groups exemplified above, the alkenyloxycarbonyl groups exemplified above, the aralkyloxycarbonyl groups exemplified above, the silyl groups exemplified above or the aralkyl groups exemplified above, and is preferably a trifluoroacetyl group;

R.sup.8 and R.sup.9 may be the same or different from each other and each represents: a straight or branched chain alkyl group having from 1 to 6 carbon atoms, such as a methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, t-butyl, pentyl, isopentyl, 2-methylbutyl, neopentyl, hexyl, 4-methylpentyl, 3-methylpentyl, 2-methylpentyl, 3,3-dimethylbutyl, 2,2-dimethylbutyl, 1,1-dimethylbutyl, 1,2-dimethylbutyl, 1,3-dimethylbutyl or 2,3-dimethylbutyl group; or an aryl group having from 5 to 12, preferably 6 to 10, carbon atoms, such as a phenyl or naphthyl group, which may be unsubstituted or may have from 1 to 4 substituents on the ring, said substituents being selected from the group consisting of amino groups, nitro groups, cyano groups, carboxy groups (which may be esterifed with the above lower alkyl groups, with the halogenated lower alkyl groups mentioned below or with the aralkyl groups exemplified above), carbamoyl groups, halogen atoms, lower alkyl groups, halogenated lower alkyl groups (such as the trifluoromethyl, trichloromethyl, difluoromethyl, dichloromethyl, dibromomethyl, fluoromethyl, 2,2,2-trichloroethyl, 2,2,2-trifluoroethyl, 2-bromoethyl, 2-chloroethyl, 2-fluoroethyl and 2,2-dibromoethyl groups), and the aliphatic acyl groups exemplified above, and is preferably a halogen atom or a halogenated lower alkyl group; and
R.sup.10 and R.sup.12 may be the same or different from each other and each represents a protecting group for a phosphoryl group or for a phosphono group, such as the aryl groups or the aralkyl groups exemplified above.
In Step A1 of Reaction Scheme A, glucosamine hydrochloride of formula (V) is reacted with the acid corresponding to the amino-protecting group R.sup.6 or with a reactive derivative of that acid. The nature of the reagent chosen will, of course, depend on the nature of the group R.sup.6 which it is wished to introduce; in the case of the preferred trifluoroacetyl group, the reagent will be trifluoroacetic acid or a reactive derivative thereof. Where the reagent is a free acid, such as trifluoroacetic acid, the reaction is preferably carried out in the presence of a condensation agent, such as dicyclohexylcarbodiimide (DCC). Where the reagent is an anhydride of the acid, such as trifluoroacetic anhydride, the reaction preferably takes place in the presence of an organic base, such as triethylamine, diisopropylethylamine, N-methylmorpholine, pyridine, 4-(N,N-dimethylamino)pyridine (DMAP), N,N-dimethylaniline, 1,5-diazabicyclo�4.3.0!non-5-ene (DBN), 1,4-diazabicyclo�2.2.2!octane (DABCO) or 1,8-diazabicyclo�5.4.0!undec-7-ene (DBU). Alternatively, where the reagent is an active ester, e.g. a trifluoroacetate such as ethyl trifluoroacetate, the reaction preferably also takes place in the presence of one of the above organic bases. The reaction in this Step prepares an amide of formula (VI).
The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the starting materials to a certain degree. Examples of suitable solvents include: halogenated hydrocarbons, especially halogenated aliphatic hydrocarbons, such as methylene chloride and chloroform; ethers, such as diethyl ether, tetrahydrofuran, dioxane and dimethoxyethane; alcohols, such as methanol, ethanol, propanol, isopropanol, butanol, isobutanol and isoamyl alcohol; amides, especially fatty acid amides, such as dimethylformamide, dimethylacetoamide and hexamethylphosphoric triamide; and sulfoxides, such as dimethyl sulfoxide.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from 0.degree. C. to 100.degree. C., preferably at room temperature. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and the solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 0.1 to 24 hours will usually suffice.
In Step A2 of Reaction Scheme A, a glycoside bond is formed by reacting the amide of formula (VI) with an alcohol of formula R.sup.7 OH (where R.sup.7 is as defined above, e.g. methanol, ethanol, benzyl alcohol or allyl alcohol) in the presence of an acid catalyst to prepare the compound of formula (VII).
The alcohol of formula R.sup.7 OH is preferably used in a large excess to serve as the reaction solvent.
There is no particular restriction on the acid to be used as the catalyst, provided that it functions as an acid and has no harmful effect on the reaction or on the reagents. Preferred acids include: mineral acids, such as hydrochloric acid or sulfuric acid; and organic acids, especially organic sulfonic acids, such as p-toluenesulfonic acid. These acids may be used in the hydrous state, if desired.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from 0.degree. C. to 200.degree. C., preferably at the reflux temperature of the reaction medium. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and the solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 0.1 to 24 hours will usually suffice.
In Step A3 of the Reaction Scheme, the diol of formula (VII), prepared as described above, is protected by introducing a group of formula R.sup.8 R.sup.9 C>, for example an isopropylidene, benzylidene or ethylidene group at the 4-position and 6-position of the compound of formula (VII); this reaction takes place in a solvent and in the presence of a catalyst to prepare a compound of formula (VIII).
There is no restriction on the nature of the reagents employed in this Step for the protection of the diol, and any such reagent commonly used for diol protection may equally be used here. Preferred examples include: aldehyde derivatives, such as benzaldehyde; ketone derivatives, such as acetone; and dimethoxy compounds, such as 2,2-dimethoxypropane or benzaldehyde dimethyl acetal.
There is also no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved. Examples of suitable solvents include: halogenated hydrocarbons, especially halogenated aliphatic hydrocarbons, such as methylene chloride or chloroform; ethers, such as dioxane or tetrahydrofuran; aliphatic hydrocarbons, such as hexane or pentane; aromatic hydrocarbons, such as benzene or toluene; esters, such as ethyl acetate; and polar solvents, e.g. amides, such as dimethylformamide, and ketones, such as acetone.
There is no particular restriction on the nature of the catalyst to be used, provided that it has no adverse effect on the reaction or the reagents, and any acid commonly used in reactions of this type may equally be used here. Examples include: organic acids, especially organic sulfonic acids, and their salts, such as p-toluenesulfonic acid, camphorsulfonic acid and pyridium p-toluenesulfonate; inorganic catalysts, such as hydrochloric acid; and Lewis acids, such as zinc chloride, aluminum chloride and stannic chloride.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from 0.degree. C. to 100.degree. C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 0.1 to 24 hours will usually suffice.
In Step A4 of Reaction Scheme A, the R.sup.6 group of the compound of formula (VIII) is eliminated to prepare a compound of formula (IX).
Many reactions can be used to remove this protecting group, the nature of the reaction depending on the nature of the protecting group, e.g. as illustrated below.
For example, when a silyl group is used as the R.sup.6 group, it can generally be eliminated by treating the compound of formula (VIII) with a compound which generates a fluorine anion, such as tetrabutylammonium fluoride. The reaction is preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved. Examples of suitable solvents include ethers, such as tetrahydrofuran and dioxane.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at about room temperature. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 18 hours will usually suffice.
If the R.sup.10 group is an aliphatic acyl group, an aromatic acyl group or an alkoxycarbonyl group, it can be eliminated by treating the compound of formula (VIII) with a base in the presence or an aqueous solvent or by reduction. There is no particular restriction on the nature of the base employed in this reaction, provided that it does not affect other parts of the molecule, and any base commonly used in reactions of this type may equally be used here. Examples of suitable bases include: alkali metal carbonates, such as sodium carbonate or potassium carbonate; alkali metal hydroxides, such as sodium hydroxide or potassium hydroxide; and concentrated methanolic ammonia. The reaction is preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved, and any solvent commonly used for hydrolytic reactions may be used. Examples of suitable solvents include: water; a mixture of water and an organic solvent, such as an alcohol (e.g. methanol, ethanol or propanol) or an ether (e.g. tetrahydrofuran or dioxane). The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from 0.degree. C. to 150.degree. C. in order to prevent side reactions. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 1 to 10 hours will usually suffice.
Elimination of the R.sup.6 group through reduction may be carried out using a reducing agent such as sodium borohydride by a conventional method.
If the R.sup.6 group is an aralkyl group or an aralkyloxycarbonyl group, elimination of the group is preferably carried out by catalytic reduction at ambient temperature using a catalyst, such as platinum or palladium-on-carbon. This reaction is preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved. Examples of suitable solvents include: alcohols, such as methanol, ethanol or isopropanol; ethers, such as diethyl ether, tetrahydrofuran or dioxane; aromatic hydrocarbons, such as toluene, benzene or xylene; aliphatic hydrocarbons, such as hexane or cyclohexane; esters, such as ethyl acetate or propyl acetate; fatty acids, such as acetic acid; and mixtures of any one or more of such organic solvents with water. Any catalyst commonly used in reduction reactions can be used for this one, and preferred examples include palladium-on-carbon, Raney nickel, platinum oxide, platinum black, rhodium-aluminum oxide, triphenylphosphine-rhodium chloride and palladium-barium sulfate.
The reaction pressure is not critical, but it is usually from 1 to 10 atmospheres.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from 0.degree. C. to 100.degree. C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature, the type of catalyst and the nature of the reagents. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 5 minutes to 24 hours will usually suffice.
If the R.sup.6 group is an alkenyloxycarbonyl group, it can usually be eliminated under the same elimination conditions as are used in the case when the R.sup.6 group is an aliphatic acyl group, an aromatic acyl group or a lower alkoxycarbonyl group. It should be noted that, when the R.sup.6 group is an allyloxycarbonyl group, elimination is particularly conveniently carried out by using palladium and triphenylphosphine or nickel tetracarbonyl, as this reaction may be carried out with the least side reactions.
In Step A5 of Reaction Scheme A, the amino moiety at the 2-position of the compound of formula (IX) is acylated, preferably with from 1.0 to 1.1 equivalents of one of the acylation agents described below, to prepare the compound of formula (X).
The acylation may be carried out by allowing this amino moiety to react with a carboxylic acid of formula R.sup.2a OH (wherein R.sup.2a is as defined above) in the presence of a condensation agent, such as dicyclohexylcarbodiimide (DCC) or carbonyldiimidazole, or with an activated acylation agent of formula R.sup.2a Y (wherein R.sup.2a is as defined above; and Y represents a leaving group, for example, a group of formula OR.sup.2a, a halogen atom (such as a chlorine, bromine or iodine atom), an aliphatic acyloxy group �such as an alkylcarbonyloxy group, e.g. an acetoxy or propionyloxy group, a halogenated alkylcarbonyloxy group, e.g. a chloroacetoxy, dichloroacetoxy, trichloroacetoxy or trifluoroacetoxy group, a lower alkoxyalkylcarbonyloxy group, e.g. a methoxyacetoxy group, or an unsaturated alkylcarbonyloxy group, e.g. an (E)-2-methyl-2-butenoyloxy group!; an aromatic acyloxy group (such as an arylcarbonyloxy group, e.g. a benzoyloxy group, a halogenated arylcarbonyloxy group, e.g. a 2-bromobenzoyloxy or 4-chlorobenzoyloxy group, a lower alkylated arylcarbonyloxy group, e.g. a 2,4,6-trimethylbenzoyloxy or 4-toluoyloxy group, a lower alkoxylated arylcarbonyloxy group, e.g. a 4-anisoyloxy group, a nitrated arylcarbonyloxy group, e.g. a 4-nitrobenzoyloxy or 2-nitrobenzoyloxy group), a trihalomethoxy group (such as a trichloromethoxy group), a lower alkanesulfonyloxy group (such as a methanesulfonyloxy or ethanesulfonyloxy group), a halogenated lower alkanesulfonyloxy group (such as a trifluoromethanesulfonyloxy or pentafluoroethanesulfonyloxy group), an arylsulfonyloxy group (such as a benzenesulfonyloxy or p-toluenesulfonyloxy group). The reaction is preferably effected in a solvent in the presence of a base.
There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved. Examples of suitable solvents include: halogenated hydrocarbons, especially halogenated aliphatic hydrocarbons, such as methylene chloride, chloroform or carbon tetrachloride; ethers, such as diethyl ether, dioxane or tetrahydrofuran; aliphatic hydrocarbons, such as hexane; aromatic hydrocarbons, such as benzene or toluene; esters, such as ethyl acetate; and polar solvents, including sulfoxides such as dimethyl sulfoxide and amides such as dimethylformamide.
There is also no particular restriction on the nature of the base employed, and any base commonly used in reactions of this type may equally be used here. Preferred examples include organic bases such as triethylamine, pyridine, DBU, DBN, N,N-dimethylaniline, N,N-diethylaniline and N,N-dimethylaminopyridine.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from 0.degree. C. to 100.degree. C., and preferably at from 20.degree. to 50.degree. C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 0.1 to 24 hours will usually suffice.
In Step A6 of Reaction Scheme A, the hydroxy moiety at the 3-position of the compound of formula (X) is modified with an R.sup.3a group to give a compound of formula (XI). This reaction is essentially the same as and may be carried out under the same conditions and using the same reagents as the acylation of the amino moiety in Step A5.
In Step A7 of Reaction Scheme A, the protecting group R.sup.7 at the 1-position of the compound of formula (XI) is eliminated to prepare a compound of formula (XII).
The nature of the reaction employed to remove this protecting group will, of course, depend on the nature of the protecting group itself, and any reaction known in the art for removing protecting groups in compounds of this type may equally be employed here.
For example, if the R.sup.7 group is a silyl group, an aralkyloxycarbonyl group, an aralkyl group, an aliphatic acyl group, an aromatic acyl group, an alkoxycarbonyl group, an alkoxymethyl group or a substituted ethyl group, its elimination may be effected in the same manner as in the case when the group R.sup.6 is to be eliminated in accordance with Step A4.
If the R.sup.7 group is a tetrahydropyranyl group, a tetrahydrofuranyl group, a tetrahydrothiopyranyl group a tetrahydrothienyl group or a vinyl group, it can usually be eliminated by treating the compound of formula (XI) with an acid in a solvent. There is no particular restriction on the nature of the acid to be used here, and preferred examples include hydrochloric acid, sulfuric acid, .beta.-toluenesulfonic acid and acetic acid.
The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved. Examples of suitable solvents include: organic solvents, such as alcohols (e.g. methanol or ethanol), ethers (e.g. tetrahydrofuran or dioxane) and mixtures of of any one or more of such organic solvents and water.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from 0.degree. C. to 50.degree. C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 18 hours will usually suffice.
If the R.sup.7 group is an alkenyloxycarbonyl group, it can be eliminated by treatment with a base under the same conditions as are used for the elimination reaction in the case where the group R.sup.7 is an aliphatic acyl group, an aromatic acyl group or an alkoxycarbonyl group. It should be noted that, when the R.sup.7 group is an allyloxycarbonyl group, elimination is conveniently carried out using palladium and triphenylphosphine or nickel tetracarbonyl, as this reaction may be carried out with the least side reactions.
If the group R.sup.7 is an allyl group, it can preferably be eliminated by reacting the compound of formula (XI) in a solvent in the presence of a catalyst to shift the double bond and convert the group into an enol ether type group, immediately followed by the addition of pyridine-iodine-water or of an inorganic acid, such as concentrated hydrochloric acid or sulfuric acid.
The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved. Examples of suitable solvents include: halogenated hydrocarbons, especially halogenated aliphatic hydrocarbons, such as methylene chloride, chloroform or carbon tetrachloride; ethers, such as diethyl ether, dioxane or tetrahydrofuran; aliphatic hydrocarbons, such as hexane; aromatic hydrocarbons, such as benzene or toluene; esters, such as ethyl acetate; and polar solvents, for example sulfoxides such as dimethyl sulfoxide and fatty acid amides such as dimethylformamide.
Examples of the catalyst which may be used here include catalysts known to be capable of moving a double bond, such as palladium catalysts, e.g. palladium chloride and palladium acetate, rhodium catalysts, e.g. 1,5-cyclooctadiene-bis�methyldiphenylphosphine!rhodium hexafluorophosphate and rhodium acetate, and iridium catalysts, e.g. 1,5-cyclooctadiene-bis�methyldiphenylphosphine!iridium hexafluorophosphate.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from 0.degree. to 100.degree. C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents, the catalyst and the solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 1 to 5 hours will usually suffice.
In Step A8 of Reaction Scheme A, the hydroxy group at the 1-position of the compound of formula (XII) thus obtained is phosphorylated to prepare a compound of formula (XIII).
The phosphorylation can be effected by forming an anion with a base in a solvent, and then by reacting this anion with a phosphorylation agent.
There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved. Examples of suitable solvents include: ethers, such as diethyl ether, dioxane or tetrahydrofuran; and halogenated aliphatic hydrocarbons, such as methylene chloride.
There is no particular restriction on the nature of the base to be used here, provided that it is capable of forming an anion, and any base commonly used for reactions of this type may equally be used here. Preferred examples include: lithium compounds, such as butyllithium and phenyllithium; and organic bases, such as DBU, DBN, DMAP, triethylamine and pyridine.
The phosphorylation agent used may be any reagent commonly employed for phosphorylation, such as dibenzyl chlorophosphate or diphenyl chlorophosphate.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from -78.degree. to 50.degree. C., preferably from -78.degree. C. to about room temperature. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and the solvent. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 24 hours will usually suffice. In Step A9 of Reaction Scheme A, the protecting groups for the compound of formula (XIII) are eliminated to prepare the compound of formula (XIV) and, if desired, any protecting group in or represented by for R.sup.3a is also eliminated.
The nature of the reactions employed to eliminate the protecting group for the phosphoric acid residue and the hydroxy-protecting group will depend principally on the nature of the protecting group, and the desired elimination reactions can be effected in any order; if desired, the protecting group for the phosphoric acid residue can be eliminated simultaneously with the elimination of the hydroxy-protecting group. However, we prefer that the protecting group for the phosphoric acid residue R.sup.10 should be eliminated last, for ease of handling.
For example, when the R.sup.10 group is an aralkyl group, such as a benzyl group, all of the protecting groups can be eliminated at one time by catalytic reduction in the presence of a palladium-on-carbon catalyst at -78.degree. C. to 25.degree. C., including the case where the hydroxy groups of R.sup.2a and/or R.sup.3a have a protecting group. Also, if the R.sup.10 group is an aryl group, such as a phenyl group, elimination of the protecting group can be effected by catalytic reduction in the presence of a palladium-on-carbon catalyst, followed by catalytic reduction in the presence of a platinum oxide catalyst.
In the case of a protecting group containing the R.sup.8 group or R.sup.9 group, it can be optionally eliminated (for example, in the case of an acetonide) by purification through silica gel chromatography. However, the protecting group can usually more conveniently be eliminated in a solvent (such as aqueous acetic acid, an ether, e.g. tetrahydrofuran or dioxane, or an alcohol, e.g. ethanol or methanol) at 0.degree. to 100.degree. C. using a catalyst such as dilute hydrochloric acid, dilute sulfuric acid or p-toluenesulfonic acid.
When a water-soluble salt of phosphoric acid is to be obtained, the compound of formula (XIV) is first washed with an inorganic acid diluted with water (such as dilute hydrochloric acid) and is then dissolved in a solvent (such as chloroform), after which a base is added.
Reaction Schemes B to E illustrate variations for preparing different products or for preparing intermediate products via different routes.
In Step B1 of Reaction Scheme B, the hydroxy group at the 3-position of the compound of formula (VIII), prepared in Step A3, is acylated with the R.sup.3a group to prepare a compound of formula (XV). The acylation is essentially the same reaction as and may be carried out using the same reagents and reaction conditions as described in Step A5.
In Step B2 of Reaction Scheme B, the protecting group R.sup.6 for the amino group at the 2-position of the compound of formula (XV) is eliminated to prepare a compound of formula (XV) in the same manner as described in Step A4.
In Step B3 of Reaction Scheme B, the amino group at the 2-position of the compound of formula (XVI) is modified with the R.sup.2a group according to the procedure described in Step A5 to prepare a compound of formula (XI).
The compound of formula (XI) thus prepared may then be subjected to the procedures described in Steps A7 to A9 to prepare a compound corresponding to the compound of formula (XIV).
In Step C1 of Reaction Scheme C, the hydroxy groups at the 4- and 6-positions of the compound of formula (XI) are eliminated to prepare a compound of formula (XVII). This may be effected using procedures similar to those described in Step A9.
In Step C2 of Reaction Scheme C, the hydroxy group at the 6-position of the compound of formula (XVII) is protected with an R.sup.11 group to prepare a compound of formula (XVIII).
The compound of formula (XVIII) can be prepared by allowing the primary hydroxy group at the 6-position of the compound of formula (XVII) to react with a compound of formula R.sup.11 Y (wherein R.sup.11 and Y are as defined above), such as chloromethyl methyl ether, benzyl chloromethyl ether, benzyl bromomethyl ether, benzyl chloroformate or 2,2,2-trichloroethyl chloroformate, at 50.degree. to 50.degree. C. in a solvent (e.g., halogenated hydrocarbon, such as methylene chloride, chloroform or carbon tetrachloride, an ether, such as diethyl ether, dioxane or tetrahydrofuran, an aliphatic hydrocarbon such as hexane, an aromatic hydrocarbon, such as benzene or toluene, an ester, such as ethyl acetate, or a polar solvent, such as dimethyl sulfoxide, dimethylformamide or acetone) using a base (e.g., DBU, DBN, DMAP, DABCO, pyridine, triethylamine, aniline, N,N-dimethylaniline or N,N-diethylaniline); or in a solvent (e.g. acetone, tetrahydrofuran or dioxane) using an aqueous solution of a base (e.g. sodium hydroxide, potassium hydroxide, potassium carbonate, sodium carbonate and sodium hydrogen carbonate).
In Step C3 of Reaction Scheme C, the hydroxy group at the 4-position of the compound of formula (XVIII) is phosphorylated to prepare a compound of formula (XIX). This reaction is essentially the same as and may be carried out under the same conditions and using the same reagents as that described in Step A8.
In Step C4 of Reaction Scheme C, the protecting groups of the compound of formula (XIX) are eliminated to prepare a compound of formula (XX). In this Step, the elimination of the protecting groups R.sup.7 and R.sup.11 for the hydroxy groups can be carried out according to the procedures described in Step A7. If a hydroxy-protecting group is present on R.sup.2a and/or R.sup.3a, elimination of these protecting groups and the protecting group R.sup.12 for the phosphoric acid residue may be carried out according to the procedures described in Step A9. However, the elimination is preferably carried out by contriving conditions such that the protecting group R.sup.12 for the phosphoric acid residue may be eliminated after any other protecting groups have first been eliminated.
Alternatively, n Step C5 of Reaction Scheme C, the protecting group for the hydroxy group at the 1-position of the compound of formula (XIX) is selectively eliminated, which may be effected according to the procedures described in Step A7, and then the hydroxy group at the 1-position of the resulting compound is phosphorylated according to the procedures described in Step A8. The hydroxy-protecting group R.sup.11 and/or the hydroxy-protecting group if present on R.sup.3a and/or R.sup.2a, and the protecting group R.sup.12 for the phosphoric acid residue may then be eliminated to prepare the compound of formula (XXI), following the procedures described in Step A9.
In Step D1 of Reaction Scheme D, the protecting group R.sup.7 for the hydroxy group at the 1-position of the compound of formula (XIX) is selectively eliminated to prepare a compound of formula (XXII). This reaction is essentially the same as and may be carried out under the same conditions and using the same reagents as the removal reactions described in Step A7 of Reaction Scheme A.
In Step D2 of Reaction Scheme D, the hydroxy group at the 1-position of the compound of formula (XXII) is replaced by a fluorine atom, using a fluorination reagent, to prepare a compound of formula (XXIII).
The reaction is preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it dissolves the starting materials at least to some degree. Examples of suitable solvents include: aliphatic hydrocarbons, such as hexane, heptane, ligroin or petroleum ether; aromatic hydrocarbons, such as benzene, toluene or xylene; halogenated hydrocarbons, such as methylene chloride, chloroform, carbon tetrachloride, the dichloroethanes, chlorobenzene or the dichlorobenzenes; esters, such as ethyl formate, ethyl acetate, propyl acetate, butyl acetate or diethyl carbonate; ethers, such as diethyl ether, diisopropyl ether, tetrahydrofuran, dioxane, dimethoxyethane or diethylene glycol dimethyl ether; and ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone, isophorone or cyclohexanone.
The nature of the fluorination reagent used here is not particularly critical and any reagent which may conventionally be used for the fluorination of alcohols may also be used in this reaction. Preferred examples include compounds of formula: (R.sup.13)(R.sup.14)NSF.sub.3 �wherein R.sup.-- and R.sup.14 are the same or different and each represents a lower alkyl group, e.g. as exemplified above (preferably methyl or ethyl group), or represent together a lower alkylene group which may optionally be interrupted by an oxygen atom. Examples of the lower alkylene group include alkylenes group having from 1 to 6 carbon atoms, such as the methylene, methylmethylene, ethylene, propylene, trimethylene, tetramethylene, 1-methyltrimethylene, 2-methyltrimethylene, 3-methyltrimethylene, 3-pentamethylene and hexamethylene groups, preferably a tetramethylene or pentamethylene groups!. The dialkylaminosulfur trifluoride compounds are preferred.
The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. In general, we find it convenient to carry out the reaction at a temperature from -20.degree. to 120.degree. C., preferably from 0.degree. C. to 100.degree. C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 0.1 hour to 5 days will usually suffice.
In Step D3 of Reaction Scheme D, the protecting group R.sup.11 for the hydroxy group at the 6-position of the compound of formula (XXIII) is eliminated to prepare a compound of formula (XXIV) and, if desired, the protecting group for the hydroxy group in the R.sup.2a group and/or R.sup.3a group is also eliminated. This Step is essentially the same as and may be carried out using the same reagents and reaction conditions as described in Step A7.
In Step D4 of Reaction Scheme D, the protecting group for the phosphoric acid residue of the compound of formula (XXIV) is eliminated, to prepare a compound of formula (XXV). This reaction is essentially the same as and may be carried out under the same conditions and using the same reagents as are described in Step A9 of Reaction Scheme A.
In Step E1 of Reaction Scheme E, the protecting group R.sup.11 for the hydroxy group at the 6-position of the compound of formula (XIX) is selectively eliminated to prepare a compound of formula (XXVI). This reaction is essentially the same as and may be carried out under the same conditions and using the same reagents as the removal reactions described in Step A7 of Reaction Scheme A.
In Step E2 of Reaction Scheme E, the hydroxy group at the 6-position of the compound of formula (XXVI) is converted to a fluorine atom to prepare a compound of formula (XXVII). This reaction is essentially the same as and may be carried out under the same conditions and using the same reagents as the fluorination reaction described in Step D2 of Reaction Scheme D.
In Step E3 of Reaction Scheme E, the protecting group R.sup.7 for the hydroxy group at the 1-position of the compound of formula (XXVII) is selectively eliminated to prepare a compound of formula (XXVIII). This Step is essentially the same as and may be carried out using the same reagents and reaction conditions as described in Step A7.
In Step E4 of Reaction Scheme E, the protecting group for the phosphoric acid residue of the compound of formula (XXVIII) is eliminated to prepare a compound of formula (XXIX). If desired, this may be followed by elimination of any hydroxy-protecting group in the group R.sup.2a and/or the group R.sup.3a, e.g. by the procedures described in Step A9 of Reaction Scheme A.
BIOLOGICAL ACTIVITY
The compounds of the present invention have been found to have activity of the Lipid A type, without (it is presently believed) the adverse toxicity of Lipid A and associated natural products or compounds derived from those natural products. This activity is illustrated by the following test.
Assay of �.sup.14 C!-Prostaglandin D2 released in cultured cells
The cells employed were a macrophage-like mouse cell line J774.1. They were seeded at approximately 5.times.10.sup.5 cells per well in 12-well dishes each containing 1 ml of a culture medium comprising Ham F-12 supplemented with 10% newborn calf serum.
The cells were then cultured at 37.degree. C. overnight, after which they were labelled with .sup.14 C by incubation with �.sup.14 C!-arachidonic acid at 37.degree. C. for 18 hours. At the end of this time, each well was washed three times, each time with 0. 5 ml of the culture medium kept at 37.degree. C. 10 .mu.mole of one of the compounds under test were then added to each well, and the cells were incubated for a further 12 hours at 37.degree. C. The culture media were then collected and centrifuged for 5 minutes at 10,000.times.G. The medium was acidified by the addition of 0.1N aqueous hydrochloric acid to a pH value of 3.0, and the prostaglandin D2 released into the medium was then extracted with a 2:1 by volume mixture of chloroform and methanol. The resulting mixture was analysed by thin layer chromatography (TLC) using as the developing solvent a mixture of chloroform, ethyl acetate, methanol, acetic acid and water in a ratio of 70:30:8:1:0.5 by volume. The radiolabelled prostaglandin D2 was located by autoradiography. The regions showing radioactivity were scraped from the TLC plates and the radioactivity was counted by a scintillation counter, thus giving a reliable measure of the amount of prostaglandin D2 produced. The amount of stimulation of prostaglandin D2 production by the test compound is a reliable measure of the Lipid A-like activity of the compound �see, for example, Zoeller et al., J. Biol. Chem., 262, No. 35, pp 17212-17220 (1987)!.
Several compounds of the present invention were and these are identified in the following Table 4 by reference to the number of the following Example in which that compound was produced. In addition, the known compound GLA-60, recognised to be the most active compound of this type publicly known at present, was tested. The results, in terms of the number of counts per minute, are shown in the following Table 4.
TABLE 4______________________________________Compound of Prostaglandin D2Example No. content (counts per minute)______________________________________ 8 123 9 1612(2R isomer) 18512(2S isomer) 18513 2014 1315 7616 26GLA-60 104______________________________________
As can be seen from the results given above, the best of the compounds of the present invention has an activity which is very significantly better than that of GLA-60, whilst all of the compounds of the present invention tested to date, all of which are shown above, exhibit, even at worst, a significant level of activity.
It is, therefore, expected that the compounds of the present invention will be useful in the treatment, prophylaxis, support and diagnosis of a variety of diseases and disorders, including those involving deficiencies in the immune system and tumorous conditions.
The compounds of the present invention may be administered to human or other patients by any suitable route and may, if desired, be formulated with conventional additives, excipients, diluents or other such agents to facilitate administration, absorption, transport to the site or activity or patient or physician acceptance, as is well known in the art. For example, they may be administered orally in the form of tablets, capsules, granules, powders or syrups; or parenterally in the form of an injection or a suppository. These pharmaceutical preparations can be prepared according to known methods using additives such as excipients, binders, disintegrators, lubricants, stabilizers or corrigents. The dose to be administered will depend on many factors, including the condition, age, and body weight of the patient, as well as the nature and severity of the disease or disorder to be treated. However, it would normally be expected to be administered in an amount of from 0.01 to 50 mg/kg per day for an adult human patient, and this may be administered in single or divided doses.





The invention is further illustrated by the following non-limiting Examples, which show the preparation of various of the compounds of the present invention.
EXAMPLE 1
2-Deoxy-2-�(3'R)-3'-hydroxytetradecanoylamino!-3-O-�(2"RS,3"SR)-2"-fluoro-3"-hydroxytetradecanoyl!-.alpha.-D-glucopyranosyl-1-phosphate
1(a) N-Trifluoroacetylglucosamine
160 g (0.742 mole) of D-(+)-glucosamine hydrochloride were dissolved in 2200 ml of methanol (99.6% purity), and 187.9 g (1.86 mole) of triethylamine were added to the resulting solution. 115.9 g of ethyl trifluoroacetate were then added dropwise to the resulting mixture, whilst ice-cooling, after which the mixture was stirred overnight at room temperature. At the end of this time, the mixture was concentrated by evaporation under reduced pressure, and then benzene (250 ml twice) and ethyl acetate (250 ml) were repeatedly added to the residue, which was then concentrated by evaporation under reduced pressure and then finally dried sufficiently in vacuo. The whole of the resulting crude trifluoroacetyl compound was used in the subsequent step (b) without purification.
1(b) Allyl 2-deoxy-2-trifluoroacetylamino-D-glucopyranoside
1850 ml of a 2% w/w solution of hydrochloric acid in allyl alcohol were added to the crude trifluoroacetyl compound obtained as described in Example 1(a) above, and the mixture was heated under reflux for 30 minutes.

However, since the reaction did not proceed, 50 mg of 4-dimethylaminopyridine was then added, and the mixture was stirred at room temperature for a further 1 hour. At the end of this time, the mixture was concentrated by evaporation reduced pressure and diluted with ethyl acetate. The ethyl acetate layer was washed with a saturated aqueous solution of sodium hydrogen carbonate and with a saturated aqueous solution of sodium chloride, in that order, after which it was dried over anhydrous magnesium sulfate. It was then filtered, and the ethyl acetate was removed by evaporation under reduced pressure. The residue was purified by chromatography through a silica gel column, using a 5:1 by volume mixture of cyclohexane and ethyl acetate as the eluent, to obtain 3.8 g of the title compound quantitatively.

12(a) Ally 2-deoxy-2-�(RS)-2',2'-difluoro-3'-(benzyloxycarbonyloxy)tetradecanoylamino!-4,6-O-isopropylidene-.beta.-D-glucopyranoside
2.2 g of (R,S)-3-benzyloxycarbonyloxy-2,2-difluorotetradecanoic acid were dissolved in 20 ml of dry methylene chloride, and 2 ml of oxalic chloride were added to the resulting solution. One droplet of dimethylformamide was then added, and the mixture was stirred at room temperature for one hour. At the end of this time, the methylene chloride was removed by evaporation under reduced pressure to obtain an acid chloride.
Meanwhile, 1.51 g of allyl 2-deoxy-2-amino-4,6-O-isopropylidene-.beta.-D-glucopyranoside �prepared as described in Example 1(d)! was dissolved in 20 ml of dry methylene chloride, and 700 mg of triethylamine were added to the resulting solution; the whole of the acid chloride prepared as described above was then added, whilst ice-cooling. The mixture was then stirred at room temperature for 1 hour, after which the methylene chloride was removed by evaporation under reduced pressure. The residue was diluted with ethyl acetate, and washed with a saturated aqueous solution of sodium hydrogen carbonate and with a saturated aqueous solution of sodium chloride, in that order, after which it was dried over anhydrous magnesium sulfate. The ethyl acetate was then removed by evaporation under reduced pressure and the residue was subjected to silica gel column chromatography, using a 2:1 by volume mixture of cyclohexane and ethyl acetate as the eluent, to obtain 2.64 g (yield 75.8%) of the title compound.
