An oligosaccharide having an affinity for fibroblast growth factor, which is composed of 8 to 18 monosaccharide residues, wherein a principal disaccharide unit comprising L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine and a process for producing the oligosaccharide comprising digesting heparan sulfate.

Oligosaccharide having affinity for fibroblast growth factor and process

This invention relates to compounds prepared by linking glycosaminoglycan to phospholipid or lipid, which are expected to exert a pharmacological effect for inhibiting metastasis because of their excellent function to inhibit adhesion of cancer cells to blood vessel endothelial cells and extracellular matrix. This phospholipid- or lipid-linked glycosaminoglycan can be produced for example by: cleaving and oxidizing reducing terminal group of glycosaminoglycan, and allowing an aldehyde group or a lactone compound of the thus-formed derivative or a carboxyl group in the glycosaminoglycan chain to react with a primary amino group of a phospholipid; or linking a glycosaminoglycan derivative to a phospholipid or a lipid by allowing a primary amino group of the derivative to react with a carboxyl group of the phospholipid or lipid. This phospholipid- or lipid-linked glycosaminoglycan is useful as a metastasis inhibitor because it has no toxicity.
