Process for recovering heparinic oligosaccharides with an affinity for cell growth factors

摘要

The oligosaccharides of the invention are composed essentially of chains: possessing a specific affinity for the anionic and cationic cell growth factor which recognize herparin, comprising at least one sequence of 5 residues matching those present in naturally occurring heparin and possessing a strongly anionic character such as that indicated in the NMR spectrum shown in FIG. 1, as well as their pharmacologically acceptable salts.
