  Synthesis and glycan priming activity of acetylated disaccharides

  摘要：

  Five disaccharides related in structure to the glycans of vertebrate mucins have been chemically synthesized using orthogonal blocking, coupling and deblocking techniques. These include 2-naphthylmethyl 3,4,6-tetra-O-acetyl-beta -D-galactopyranosyl-(1 --> 4)-2-acetamido-3,6-di-O-acetyl-2-deoxy-beta -D-glucopyranoside (6), 2-naphthylmethyl 2-acetamido-3,4,6-tri-O -acetyl-2-deoxy-beta -D-glucopyranosyl-(1 --> 3)-2,4,6-tri-O -acetyl-beta -D-galactopyranoside (14), 2-naphthylmethy12,3,4,6-tetra-O-acetyl-beta -D-galactopyranosyl-(1 --> 3)-2-acetamido-4,6-di-O-acetyl-2-deoxy-alpha -D-galactopyranoside oside (20), 2-naphthylmethyl 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-beta -D-glucopyranosyl-(1 --> 3)-2-acetamido-4, 6-di-O -acetyl-2-deoxy-or-D-galactopyranoside (23) and 2-naphthylmethyl 2-acetamido-3,4, 6-tri-O-acetyl-2-deoxy-beta -D-glucopyranosyl-(1 --> 6)-2-acetamido-3,4-di-O-acetyl-2-deoxy-alpha -D-galactopyranoside (27). These per-O-acetylated compounds were fed to U-937 cells to test their ability to prime oligosaccharide synthesis, inhibit glycoprotein biosynthesis and alter adhesion to E-selectin expressed on endothelial cells. The results show that 6, 14, and 20 served as substrates for oligosaccharide synthesis. The generation of glycoside-primed glycans altered the formation of glycoproteins on the cell surface and inhibited cell adhesion dependent on E-selectin. (C) 2000 Elsevier Science Ltd.

  Metabolic decoys are synthetic analogs of naturally occurring biosynthetic acceptors. These compounds divert cellular biosynthetic pathways by acting as artificial substrates that usurp the activity of natural enzymes. While O-linked glycosides are common, they are only partially effective even at millimolar concentrations. In contrast, we report that N-acetylglucosamine (GlcNAc) incorporated into various thioglycosides robustly truncate cell surface N- and O-linked glycan biosynthesis at 10-100 mu M concentrations. The > 10-fold greater inhibition is in part due to the resistance of thioglycosides to hydrolysis by intracellular hexosaminidases. The thioglycosides reduce beta-galactose incorporation into lactosamine chains, cell surface sialyl Lewis-X expression, and leukocyte rolling on selectin substrates including inflamed endothelial cells under fluid shear. Treatment of granulocytes with thioglycosides prior to infusion into mouse inhibited neutrophil homing to sites of acute inflammation and bone marrow by similar to 80%-90%. Overall, thioglycosides represent an easy to synthesize class of efficient metabolic inhibitors or decoys. They reduce N-/O-linked glycan biosynthesis and inflammatory leukocyte accumulation.
