标题:Peptidodisaccharides as oligosaccharide mimetics
发明人：SABESAN SUBRAMANIAM
权利人:DU PONT
摘要: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.
