Polysaccharides containing carboxyl functional groups substituted by a hydrophobic precursor door by a spacer at least one trivalent.

摘要

[0001] The present invention relates to new derivatives of polysaccharides having carboxyl functional groups which are partially substituted by at least two radicals hydrophobic, said hydrophobic radicals are identical or different, being carried by a spacer, at least one trivalent. [0002] It also relates to their methods of synthesis. [0003] The invention also relates to the use of the polysaccharides functionalized according to the invention for the preparation of pharmaceutical compositions comprising one of the polysaccharides according to the invention, and at least one active substance.
