Abstract
This invention relates to glucopyranose compounds of formula (I) and (IA) ##STR1## and the non-toxic salts thereof wherein the substituents are as defined herein. Such materials possess enhancing activity of cellular immunity (e.g. mitogenic activity) to living tissue and therefore are useful as anti-tumor agents.
Description
This application is a continuation in part, of U.S. application Ser. No. 938,308, filed Dec. 5, 1986, now abandoned and U.S. application Ser. No. 188,873 filed May 2, 1988, now abandoned.
This invention relates to glucopyranose derivatives.
More particularly, this invention relates to
(1) novel glucopyranose derivatives (compounds);
(2) processes for their preparation; and
(3) immunity-enhancing agents and/or anti-tumor agents containing as active ingredient the present derivatives.
Gram-negative germs (e.g. cholera germs, salmonella germs, colon bacillus) have compounds known as lipopolysaccharides (abbreviated as LPS) on the outer cell membrane, and it was thought that such compounds induced endotoxin shock.
It was known that LPS have various bioactivities including fetal toxicity; this is why it is so named an endotoxin. For example, LPS have a pyrogenetic action, a hemorrhage action, can induce encephalomyelitis, arthritis, and have a blastogenic action (macrophage activating action, B cell mitogenic activity, producing action of non-specific antibody, enhancing activity of cellular immunity etc.) and anti-tumor action (INF (interferon) inducing action, TNF (tumor necrosis factor) inducing action etc.).
Especially, LPS is effective as a non-specific immunity agent, and has an action inducing hemorrhage necrosis of tumor cells specifically by its TNF inducing activity, and therefore can be useful as an anti-tumor agent.
LPS is also useful for its inducing activity of IL-1 (interleukin-1) or interferon, not only enhancing its activity of cellular immunity but also stimulating of NK (natural killer) activity.
On the other hand, LPS is constituted from three kinds of materials, i.e. acidic protein, macromolecular polysaccharides and phospholipid, and the phospholipid but has been found as its active site by Westphal, Ludertz et al. ##STR2##
The phospholipid shown above is called lipid A, and it was known that lipid A alone possesses various activities like LPS.
The absolute structure of lipid A was unknown for many years, but recent studies have made clear that its structure is a disaccharideamine combined with fatty acids and phosphoric acids as shown below. See Nippon Saikin-gaku Zasshi 40(1), 57 (1985) and Proc. Natl. Acad. Sci. U.S.A., 80, 4624 (1983): ##STR3##
As a result of these recent studies, it has been discovered that each subunit above possesses activities like lipid A. In particularly, the reducing subunit was isolated as a biosynthesis precursor and was named lipid X. See Biol. Chem., 256, 10690 (1981) and Proc. Natl. Acad. Sci., 80, 4624 (1983).
Futher, a compound combined with a hexadecanoyl group on the hydroxy group of the β-hydroxytetradecanoyl group on the 2nd position of lipid X as ester is named lipid Y.
Patent applications have been filed on the above lipid A, lipid X and lipid Y by Wisconsin Alumni Research Foundation. See WO-8404526 or EP-143840.
Non-reducing subunits were not found to be naturally occuring, and some of them were synthesized chemically, i.e. compounds of general formula: ##STR4## Examples are: Compound 1:
R1 = ##STR5## R2 =--H Compound 2:
R1 =--CO--C13 H27
R2 =--PO(OH)2
Compound 3:
RA 1= ##STR6## R2 =--PO(OH)2 See Agric. Biol. Chem., 48(1), 251 (1984) and FEBS LETT., 167, 226 (1984).
Patent applications relating to the above compounds have been published. See Japanese Patent Publication No. 61-126093 and 61-126094.
Further, compounds replacing the hydroxy group on the 1st position with a hydrogen atom has benn described, i.e. compounds of general formula: ##STR7## wherein A represents O or NH, R2' represents C14 or C14 -O-C14, R3' and R4' represent a hydrogen atom or P, C14 represents a tetradecanoyl group, C14 -O-C14 represents a (3-tetradecanoyl)-tetradecanoyl group, and P represents a phosphoryl group, respectively. Stereo configuration of AR2' on the 3rd position is α-configuration or β-configuration. See Japanese Patent Publication No. 61-172867.
We, the present inventors, succeeded in synthesizing novel compounds by introducing the following chemical modifications into a non-reducing subunit:
(1) conversion of the phosphoric acid residue on the 4th position into a sulfuric acid residue,
(2) introduction an aryl group (benzene ring or naphthalene ring) into the terminal of the acyl chain on the 2nd and 3rd positions,
(3) conversion of the hydroxy group on the 1st position into a hydrogen atom in some compounds,
(4) conversion of the hydroxymethyl group on the 5-position into a methyl group, hydrogen atom or a sulfoxymethyl group (--CH2 OSO3 H) in some compounds, and we confirmed that these novel compounds possess excellent pharmacological activities like lipid-A. The present invention was thus achieved.

The present invention is concerned with all compounds of general formulae (I) and (IA) in the "natural" form or its enantiomeric form, or mixtures thereof, more particularly the racemic form consisting of equimolecular mixtures of the natural and its enantiomeric form.
As will be apparent to those of ordinary skill in the art, the compounds depicted in general formulae (I) and (IA) have at least five centers of chirality.
This is, when the carbon atoms of the 1-, 2-, 3-, 4- and 5-positions of the sugar skeleton and the alkyl or alkylene groups represented by R, R1, R3, R5, W1, W2 or W3 are branched-chain, it is possible to occur the centers of chirality.
The presence of chirality leads, as is well known, to the existence of isomerism.
Thus, all isomers and mixtures thereof which have those side-chains attached to the sugar ring carbon atoms in positions 2 and 4 in the cis-configuration and those side-chains attached to the sugar ring carbon atoms in positions 3 and 5 in the cis-configuration, being such a configuration that the former side-chains (those in position 2 and 4) and the latter side-chains (those in position 3 and 5) are trans with respect to each other and have R or W1 groups in the 1-position of sugar are to be considered within the scope of the present invention.
The present invention not only pertains to chemical compounds per se and non-toxic salts thereof, but also encompasses processes for their preparation.

The reaction using the compound of the general formula (III) wherein R is a hydroxy group leads to the production of small amounts of by-product in which the sulfoxy groups are introduced at 1-position as well as at the 4-position. The by-product may be removed by purification described hereinafter.

From the above results, compounds of example No. 1(1) and 1(t) at the dose of 3 mg/body on Day 14 (4 day after administration) exhibit a significant effect on tumor regression.
For the treatment of immuno deficiencies or tumor, the compounds of the present invention of general formulae (I) and (IA) or non-toxic salts thereof may normally be administered systemically or partially; usually by oral or parenteral administration.
The doses to be administered are determined depending upon age, body weight, symptoms, the desired therapeutic effect, the route of administration, and the duration of the treatment etc. In the human adult, the doses per person per dose are generally between 0.1 mg and 100 mg, by oral administration, up to several times per day, and between 10 μg and 10 mg, by parenteral administration to several times per day.
As mentioned above, the doses to be used depend upon various conditions. Therefore, there are cases in which doses lower than or greater than the ranges specified above may be used.
Solid compositions according to the present invention for oral administration include compressed tablets, dispersible powders and granules. In such solid compositions, one or more of the active compound(s) is or are, admixed with at least one inert diluent such as lactose, mannitol, glucose, hydroxypropylcellulose, microcrystalline cellulose, starch, polyvinylpyrrolidone or magnesium metasilicate aluminate. The compositions may also comprise, as is normal practice, additional substances other than inert diluents e.g. lubricating agents such as magnesium stearate, disintegrating agents such as cellulose calcium gluconate, and assistant for dissolving e.g. arginine, glutamic acid or amino-acid such as aspartic acid. The tablets or pills may, if desired, be made into gastric film-coated or enteric film-coated tablets or pills, such as sugar-coated, gelatin-coated, hydroxypropyl cellulose-coated or hydroxypropylmethyl cellulose phthalate-coated tablets or pills and, two or more of layers may be used. The compositions for oral administration also include capsules of absorbable material such as gelatin.
Liquid compositions for oral administration include pharmaceutically-acceptable emulsions, solutions, suspensions, syrups and elixirs containing inert diluents commonly used in the art such as distilled water or ethanol. Besides inert diluents such compositions may also comprise adjuvants such as wetting and suspending agents, and sweetening, flavoring, perfuming and preserving agents.
Other compositions for oral administration include spray compositions which may be prepared by known methods and which comprise one or more of the active compound(s).
Preparations for injection according to the present invention for parenteral administration include sterile aqueous or non-aqueous solutions, suspensions or emulsions. Examples of aqueous solvents or suspending media are distilled water for injection and physiological salt solution. Examples of non-aqueous solvents or suspending media are propylene glycol, polyethylene glycol, vegetable oils such as olive oil, alcohols such as ethanol, POLYSORBATE 80 (registered Trademark). These compositions may also include adjuvants such as preserving, wetting, emulsifying, dispersing agents and assistant agents for dissolving (e.g. arginine, glutamic acid or amino-acid such as aspartic acid). They may be sterilized, for example, by filtration through a bacteria-retaining filter, by incorporation of sterilizing agents in the compositions or by irradiation. They may also be manufactured in the form of sterile solid compositions which can be dissolved in sterile water or some other sterile injectable medium immediately before use.
Other compositions for parenteral administration include liquids for external use, and endermic liniments such as ointments, suppositories and pessaries which comprise one or more of the active compound(s) and may be prepared by known methods.
Throughout the specification including the claims, the compounds of the present invention and termed derivatives of glucopyranose or 1,5-anhydro-glucitol having the following skeletal structure: ##STR40##

Unless otherwise specified, "IR" was measured by the KBr tablet method.
Pivaloyl chloride (1.37 ml) was added to an ice-cooled solution of β-hydroxymiristic acid (2.60 g) in methylene chloride (20 ml), and the mixture was stirred for 30 mins. The solution was added slowly to an ice-cooled solution of benzy 2-deoxy-2-amino-4,6-O-isopropylene-β-D-glucopyranoside (Agric. Biol. Chem., 48(1), 251 (1984); 2.6 g) and triethylamine (1.67 ml) in methylene chloride (20 ml).
The reaction mixture was stirred for 30 mins with ice-cooling and further for 2 hrs at room temperature and then diluted with a mixture of hexane and ethyl acetate (n-C6 H14 :EtOAc=1:2; 20 ml). The solution was washed with 1N hydrochloric acid, water and brine, successively dried and evaporated. The residue was purified by column chromatography on silica gel (EtOAc:CH2 Cl2 =3:2) to give the title compounds (3R-compound: 1.71 g; 3S-compound: 2.69 g) having the following physical data. 3R-compound:
