    • A method for producing a chondroitin (CH) with a desired sugar chain length; a method for producing a fraction containing a CH with a substantially single sugar chain length; etc. There is provided a method for producing a CH with desired sugar chain length, comprising alternately performing the steps (a) allowing a receptor substrate having a glucuronic acid residue at its non-reducing end (when this step is performed after the step (b), sugar chain obtained by the step (b)), an N-acetylgalactosamine donor and an N-acetylgalactosamine transferase to coexist in a reaction system and (b) allowing a receptor substrate having an N-acetylgalactosamine residue at its non-reducing end (when this step is performed after the step (a), sugar chain obtained by the step (a)), a glucuronic acid donor and a glucuronic acid transferase to coexist in a reaction system.

    • 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.
