Hexadecasaccharides with antithrombotic activity, including a covalent bond and an amino chain

A hexadecasaccharide of general formula (I):

• in which:
• T represents an —NH—CO—(CH2)5—NH2 group,
• R represents a (C1-C6)alkoxy radical, in particular a methoxy radical or an —OSO3− radical,
• R1 represents a (C1-C6)alkoxy radical, in particular a methoxy radical or an —OSO3— radical,
• R2 represents a (C 1-C6)alkoxy radical or an —OSO3— radical,
• R3 represents a (C1-C6)alkoxy radical, in particular a methoxy radical or an —OSO3− radical, or else R3 constitutes an —O—CH2— bridge, the —CH2— group being bonded to the carbon atom bearing the carboxylic function on the same ring,
• Pe represents a saccharide chain of following formula:
• and also the pharmaceutically acceptable salts thereof.
