PROCESS FOR THE PREPARATION OF N,O-SULPHATED HEPAROSANES

摘要

The new N,O-sulphated heparosanes are build of chain or a mixture of chains with molecular mass from 1500 to 15000 Da of a repeating disaccharide structure of formula wherein E represents acetyl group of 0 to 80% of the disaccharide ressidues of the N,O-sulphated heparosanes and in the rest disaccharide ressidues a sulphate group and obtionally a hydrogen atom, G is a hydrogen atom or a sulphate group, and the pharmaceutically accetable salts thereof.
