Chemoselective ligation of acetylated 1-maleimidosugars to peptides for the preparation of neoglycopeptides [2]

Department of Biology, Yonsei University, Seoul 120-749, KoreaReceived July 4, 2000The biological functions of oligosaccharides in glycopro-teins and glycolipids have been extensively investigated bychemists, biochemists and biologists. The cell-surface oli-gosaccharides are known to contribute to many importantbiological roles including cell-cell communication, cell adhe-sion, cell growth, bacterial and viral infection.
