摘要

The invention relates to 3-deoxy oligosaccharides of formula I: (see formula I) in which - X represents an -OSO3~ radical, a radical of formula - R-O, a radical of formula: (see formula II) or a radical of formula: (see formula III) - Y represents a radical of formula: (see formula IV) - R represents an alkyl radical, - R1, R3, R5, R7, R8, R10, R12 and R13 represent a hydroxyl radical, an alkoxy radical or an -OSO3~ radical, R2, R4, R6, R9 and R11 represent a hydrogen atom, a hydroxyl radical, an alkoxy radical or an -OSO3~ radical, with the proviso that at least R2 or R4 or R6 or R9 or R11 represents a hydrogen atom, and their pharmaceutically acceptable salts with a base.
