  • Patent number: 5100913
    Abstract: The present invention relates, by way of novel industrial products, to the sulfonylphenyl-.beta.-D-thioxyloside compounds of the formula ##STR1## in which: X is a sulfur atom or an oxygen atom;R is a C.sub.1 -C.sub.4 alkyl group, a substituted amino group NR.sub.1 R.sub.2 (where R.sub.1 and R.sub.2, which are identical or different, are each a C.sub.1 -C.sub.4 alkyl group, it being possible for R.sub.1 and R.sub.2, taken together, to form a piperidinyl or morpholinyl group with the nitrogen atom to which they are bonded) or a phenyl group which is unsubstituted or substituted in the para position by a cyano group or by a halogen atom; andY is the hydrogen atom or an aliphatic acyl group.These compounds are useful in therapeutics, especially as venous antithrombotics.
