Glucopyranose derivatives

FIELD OF THE INVENTION
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.
BACKGROUND OF THE INVENTION
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 .beta.-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:
R.sup.1 = ##STR5## R.sup.2 =--H Compound 2:
R.sup.1 =--CO--C.sub.13 H.sub.27
R.sup.2 =--PO(OH).sub.2
Compound 3:
R.sup.A 1= ##STR6## R.sup.2 =--PO(OH).sub.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, R.sup.2' represents C.sub.14 or C.sub.14 -O-C.sub.14, R.sup.3' and R4' represent a hydrogen atom or P, C.sub.14 represents a tetradecanoyl group, C.sub.14 -O-C.sub.14 represents a (3-tetradecanoyl)-tetradecanoyl group, and P represents a phosphoryl group, respectively. Stereo configuration of AR.sup.2' on the 3rd position is .alpha.-configuration or .beta.-configuration. See Japanese Patent Publication No. 61-172867.

The compounds of the present invention may easily be converted into corresponding salts by methods known per se, e.g. methods described hereafter.
The salts in the present invention are preferably non-toxic. The non-toxic salts herein referred to mean salts of cations such that the salt is relatively innoxious to the living body (animals including human beings) tissues and that the effective pharmacological properties of the compounds of general formulae (I) and (IA) are not impaired by side effect(s) resulting from the cations when used in an amount required for the prevention and/or treatment of the desired conditions. Water-soluble salts are preferable.
Suitable salts include, for example, a salt of an alkali metal such as sodium, potassium, a salt of an alkaline earth metal such as calcium, magnesium, an ammonium salt and a pharmaceutically acceptable (non-toxic) amine salt.
Amines suitable for forming such salts with a sulfo group are well known and include, for example, those amines which are theoretically obtained by substituting one or more of hydrogen atom(s) of ammonia by other group(s). These groups, which may be the same or different when one or more hydrogen atom(s) are substituted, are selected from, for example, alkyl group(s) of from 1 to 6 carbon atom(s) and hydroxyalkyl group(s) of from 1 to 3 carbon atom(s). Suitable non-toxic amine salts include salts of a tetraalkylammonium group, such as tetramethylammonium salt and salts of an organic amine, such as methylamine, dimethylamine, cyclopentylamine, benzylamine, phenthylamine, piperidine, monoethanolamine, diethanolamine, lysine and arginine.
Salts are obtained from the compounds of the present invention of general formulae (I) and (IA), by methods known per se, for example, by reacting a compound of the general formula (I) or (IA) and a suitable base such as a hydroxide or carbonate of an alkali metal or alkaline earth metal, ammonium hydroxide, ammonia or an organic amine in theoretical amounts in an appropriate solvent.
The salts can be isolated by freeze-drying the solution, or by filtration if salts are sufficiently insoluble to the reaction solution, or if necessary, by removing part of the solvent followed by filtration.

Mitogenic activity means activity of activating mitogenic cell division, and in this test system, the amount of tymidine taken into lympha cells was measured and a ratio determined against a blank control call (Blastogenic index) was calculated.
For example, adding the compound prepared in example 1(c) to the test system induced 30 times the amount of tymidine taken into the lympha cells versus the control.
The amounts were measured by density of a radiolabel.
Mytogenic activity in vitro was measured by the following method (See Procedure Method of Immunoexperiment pp 315 published by Japan Immunology Society).
C3H/He male mice 6 weeks old were killed by bloodletting, and their spleens were isolated and homogenized. Homogenizing liquids were filtered with gauze, and suspending cells were prepared with PBS solution. After washing, lymphacytes fractions were gathered with lympholight M. Lymphacytes were suspended in RPMI 1640 cultivation solution (10% FEBS), and the solution was divided into 5.times.10.sup.5 cells/180 .mu.l/wells. Ten times concentration of the terminal concentration (1 .mu.g/ml) of the compounds of the present invention were added with 20 .mu.l portions to each of the wells.
In an atmosphere of a mixed gas of 5% CO.sub.2 -95% O.sub.2, the cells were cultivated for 24 hrs at 37.degree. C. After cultivation, .sup.3 H-tymidine 0.5 .mu.Ci/20 .mu.l was added to the each cells. Cultivation was continued at 37.degree.
