Patent ID: 8557968

Claim:
A biotinylated hexadecasaccharide of general formula I: in which: T represents a sequence T 1 or T 2 having the following formulae: Biot represents the group: R represents a (C 1 -C 6 )alkoxy radical, or an —OSO 3 − radical; R 1 represents a (C 1 -C 6 )alkoxy radical, or an —OSO 3 − radical; R 2 represents a (C 1 -C 6 )alkoxy radical or an —OSO 3 − radical; R 3 represents a (C 1 -C 6 )alkoxy radical, or an —OSO 3 − radical, or alternatively R 3 constitutes an —O—CH 2 — bridge, the —CH 2 — group being linked to the carbon atom bearing the carboxylic function on the same ring; and Pe represents a saccharide sequence having the following formula: and a pharmaceutically acceptable salt thereof.
