5-thioxylose compounds, especially 5-thioxylopyranose compounds, a process for their preparation, and their use for treating and/or inhibiting thromboses, especially venous thromboses. The compounds correspond to formula I:
in which the pentapyranosyl group represents a free or substituted 5-thio-β-D-xylopyranosyl group; R′, R″ and R′″ each independently represent a hydrogen atom, a C2-C6 acyl group, or two adjacent ones of them form a 1-methylethylidene bridge; X1 and X2 each represent carbon or nitrogen; Y1 and Y2 each independently represent carbon, nitrogen, sulfur or oxygen, with the proviso that if Y2 represents oxygen or sulfur, then Y1 represents carbon or nitrogen; R1, R2, R3, R4 and R5 each independently represent hydrogen, a COOR6 group where R6 represents hydrogen or a C1-C4 alkyl group optionally substituted by a phenyl ring, a halogen atom or a —COOR6 group; a C1-C4 alkoxy group; a C1-C6 acyl group; a benzoyl group or a phenyl ring; and the addition salts and/or active metabolites of such compounds.
