DISACCHARIDE DERIVATIVES
FIELD OF THE INVENTION
This invention relates to a novel disaccharide derivative and a salt thereof which exhibit, excellent antitumor activity and low toxicity / and is useful as an antitumor agent-
BACKGROUND OF THE INVENTION
Natural lipid A has mitogenic activity, i.e., an activity to stimulate lymphocytes to cause blast transformation,, which accelerates increase of lymphatic cells thereby to enhance immunity, an activity to derive a tumor necrosis factor,, and the like, and is# therefore, promising as treating and prophylactic agent.' for many diseases'caused by reduction of Immune function, such as various infectious diseases, or antitumor agents.
Known derivatives oi natural lipid A include those described in Japanese Patent Application (OPI) Nos. 48497/84, 53295/86, and 227586/86 (the term u,OPI8' as used herein means "unexamined published Japanese patent application.0" )- Among them* 2-deoxy-6-0-(2-deoxy-2~C(R)~3«dodeca~ noyloxytetradecanoylamino3-4-0-phosphono-3-0-[(R)-4-tetra-decanoyloxytetradecanoyl] -8 -D-giucopyranosyl)-3-0-C (R)-3-hydroxytetradecanoyl3-2-[(R)-3-hydroxytatradecanoylamino3-l-O-phosphono-a-D-glucopyranose disclosed in Japanese Patent
Application (OPI) Wo. 53295/86 (hereinafter referred to as Compound A) is known to have physiological activities equal to or even higher than natural lipid A as reported in Eur- J, Biochem.. Vol. 148, 1-5 (1985). Compound A, however, is of low practical use due to high toxicity similar to natural lipid A.
Japanese Patent Application (OPI) 227586/86 (Chemical Abstracts, Vol. 106, 67627k, 1987) discloses disaccharid lipid A analogues of the formula:

wherein C0CH2CHR3(CH?) Me; R2 = C0CH2CHR4(CH2) Me; id, n =
8-12; R3, R = H, OH; R6, R7 = alkanoyl .
These analogues were shown to have tumor-necrosis factor inducing activity in mice.
In Infection and Immunity, 225-237, 1985, S. Kotani, et al, disclose a synthetic compound,^(1-6) D-glucosamine disaccharide l,4'-bisphosphate, 15 which is acvlated at the 2'-amino and 3'hydroxy1 groups with
(R)-3-dodecanovloxytetradecanoyl and (R)-3~tetradecanoyloxvtetradecanoyl groups, respectively, and has (R)-3-hydroxvtetradecanoy1 groups at 2«amino and 3~hvdroxyl groups. This compound exhibited full endotoxic activities identical to or sometimes stronger than those of a reference lipid A from an 20 Escherichia choli Re-mutant.
In Infection and Immunity, 2636-2644, 1987, L. Brade, et al, investigated the immunogenicity and antigenicity of synthetic lipid A and partial structures thereof, among them those compounds which varied in the 25 position of phosphate (1-mono-, 4'-mono-, and l,4'~bisphosphate) and in the acylation (type, number and distribution of fatty acids).
It has been keenly demanded to develop compounds exhibiting useful physiological properties with reduced toxicity.

TSST EXAMPLE
Fibrosarcoma cells (Meth A} (2 x 10 ) induced in a BMiB/c mouse by methyl chlolanthrene were in.tracutaneously implanted to the flank of seven BAL3/c mice per group- A 5 triethylamine salt of each of the compounds according to the present inventin as shown in Table 1 below was dissolved or suspended in a 0®1% (v/v) triethylamine aqueous solution to prepare a 500 Vg/ml solution or suspension* The solution or suspension was administered to the x-aice at a dose level of 10 100 Pg/mouse through the tail vein on the 7th.. 12th, and 21st days from the implantation-
The antitumor effect {%} on growth of the fibrosarcoma was determined by dividing the average tumor weight of the test group on the 21st day by the average tumor 15 weight of the control group (non-treated group) and multiplying the quotient by 100 -
For comparison, the same evaluation was made by using Compound A as a comparative compound- The results obtained are shown in Table 1.

It can toe seen from Table 1 that the compounds 15 according to the present invention exhibit antitumor activity equal or higher than Compound A.
TEST EXAMPLE 2 A triethylamine salt of each of the compounds according to the present invention as shown in Table 2 below 20 was dissolved or suspended in a 5% (w/v) glucose aqueous solution containing 0.1 (v/v) triethylamine to prepare a 100 pg/ml solution or suspension. The solution or suspension was administered to three NSW male rabbits per group at
a dose level of 50 yg/kg-b.w- "through the ear vein for consecutive three days. The toxicity was evaluated by the number of dead animals after 24 hours from the final administration/the number of test animals. For comparison,
Compound A was administered at. a level of 5 yg/kg-b. The results obtained are shown in Table 2»
