  • Patent number: 5756712
    Abstract: Methods are provided to replace the ether oxygen linkage of oligosaccharides with a peptide link, --NHC(O)--, where the nitrogen atom is linked to the anomeric carbon atom of the sugar. A new family of building blocks for combinational synthesis, peptidodisaccharides, is provided containing the peptide linkage. Synthesis is more facile than with the oxygen-linked carbohydrates; the resulting compounds are expected to be more stable to enzymatic and chemical hydrolysis and to be amenable to automated synthesis.

  • Patent number: 5733892
    Abstract: 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.
