Patent ID: 7943595

Claim:
A method for the treatment of thromboembolic disorders which comprises administering to a patient in need of such treatment a therapeutically effective amount of a compound of formula (I): in which: the wavy line denotes a bond situated either below or above the plane of the pyranose ring, the formula (Po): denotes a polysaccharide, comprising n identical or different monosaccharide units, bonded via its anomeric carbon to Pe, in which the formula: represents a monosaccharide unit with a pyranose structure chosen from hexoses, pentoses and the corresponding deoxy sugars, this unit being bonded via its anomeric carbon to another monosaccharide unit and the hydroxyl groups of this unit being substituted by identical or different R 1 groups, Pe represents a pentasaccharide of structure: h is 1 or 2, n is an integer from 0 to 25, R 1 represents the -T-Biot linkage, a (C 1 -C 6 )alkoxy group or an —OSO 3 − group, R 2 represents the -T-Biot linkage, a (C 1 -C 6 )alkoxy group or an —OSO 3 − group, R 3 represents the -T-Biot linkage or a (C 1 -C 6 )alkoxy group, R 4 represents the -T-Biot linkage, a (C 1 -C 6 )alkoxy group or an —OSO 3 − group, or else R 4 constitutes an —O—CH 2 —bridge, the —CH 2 —group being bonded to the carbon atom carrying the carboxyl functional group on the same ring; at least one of the R 1 , R 2 , R 3 or R 4 substituents represents a -T-Biot group, W represents an oxygen atom or a methylene group, T represents one of the linkages chosen from: NH, in which j and k are identical or different integers from 1 to 10; Biot represents the group: or a pharmaceutically acceptable salt thereof.
