  SYNTHESIS OF SIALYL- AND SULFO-Le^x/Le^aANALOGS CONTAININGN-ALKYL-1-DEOXYNOJIRIMYCIN AS POTENTIAL SELECTIN BLOCKERS

  摘要：

  A series of novel sialyl- and sulfo-Le(x)/Le(a) oligosaccharides containing N-alkyl-1-deoxynojirimycin as potential selectin blockers have systematically been synthesized via the suitably protected intermediates containing N-benzyloxycarbonyl-1-deoxynojirimycin. Some of the synthetic oligosaccharides strongly inhibited the adhesion of HL60 cells to IL-1beta-stimulated HUVECs.
