- β-D-phenylthioxylosides, their method of preparation and their use as therapeutic agents
-
The present invention relates, by way of novel industrial products, to the β-D-phenylthioxyloside compounds of the formula STR1 in which: X represents a sulfur atom or an oxygen atom; R1, R2 and R3, which are identical or different, each represent a hydrogen atom, a nitro group, a cyano group, a group --CO--R (in which R represents a C1 -C4 alkyl group or a trifluoromethyl group), an amino group, an acetamido group (NHCOCH3), a C1 -C4 alkoxy group, a trifluoromethyl group or a phenyl group substituted by one or more cyano, nitro or trifluoromethyl groups, it being possible for R1 and R2, taken together, to form, with the phenyl group to which they are bonded, a β-naphthalenyl group which is unsubstituted or substituted by one or more cyano, nitro or trifluoromethyl groups; and Y represents the hydrogen atom or an aliphatic acyl group. These compounds are useful as therapeutic agents, especially as venous antithrombotics.
