Abstract
The invention relates to 3-deoxy oligosaccharides of formula I: ##STR1## in which X represents an --OSO.sub.3.sup.- radical, a radical of formula R--O, a radical of formula: ##STR2## or a radical of formula: ##STR3## Y represents a radical of formula: ##STR4## R represents an alkyl radical, R.sub.1, R.sub.3, R.sub.5, R.sub.7, R.sub.8, R.sub.10, R.sub.12 and R.sub.13 represent a hydroxyl radical, an alkoxy radical or an --OSO.sub.3.sup.- radical, PA1 R.sub.2, R.sub.4, R.sub.6, R.sub.9 and R.sub.11 represent a hydrogen atom, a hydroxyl radical, an alkoxy radical or an --OSO.sub.3.sup.- radical, with the proviso that at least R.sub.2 or R.sub.4 or R.sub.6 or R.sub.9 or R.sub.11 represents a hydrogen atom, and their pharmaceutically acceptable salts with a base.
