3-Deoxyoligosaccharides, process for their preparation and pharmaceutical compositions containing them.

摘要

The invention relates to 3-deoxyoligosaccharides of formula I: <IMAGE> in which, - X represents a radical -OSO<->3, a radical of formula R-O, a radical of formula <IMAGE> or a radical of formula, <IMAGE> - Y represents a radical of formula: <IMAGE> - R represents an alkyl radical, - R1, R3, R5, R7, R8, R10, R12 and R13, represent a hydroxyl radical, an alkoxy radical or a radical -OSO<->3, - R2, R4, R6, R9 and R11, represent a hydrogen atom, a hydroxyl radical, an alkoxy radical or a radical -OSO<->3, provided however that at least R2 or R4 or R6 or R9 or R11, represents a hydrogen atom, and their salts with a pharmaceutically acceptable base.I
