Production and use of polysaccharide compounds chitosan-modified and improved method for the preparation of compounds of drug-HES

摘要

Ligation product (I) of m molecules of a polysaccharide X with a polysaccharide A, being selected polysaccharide A group chitins or chitosans, m is an integer between 1 and 10,000, and the bond between X and A is a union amine or amide, wherein X polysaccharide is completely or partially substituted, the substituents being chosen polysaccharide X the group consisting of hydroxyethyl groups and carboxymethyl groups and X being the polysaccharide starch, amylose and / or amylopectin.
