  High performance polymer supports for enzyme-assisted synthesis of glycoconjugates

  摘要：

  Efficient and practical methodology for the construction of carbohydrates, including oligosaccharide derivatives and sphingoglycolipids, was established on the basis of a water-soluble polymer supports having unique linkers that can be cleaved by specific conditions. Novel glycomonomers for the construction of polymer supports were synthesized and copolymerized with acrylamide to give three types of water-soluble glycopolymers having primer sugars through the specific linkers containing (i) p-substituted benzyl group, (ii) L-phenylalanine residue, and (iii) ceramide-mimetic L-serine derivative, respectively. These glycopolymers were employed for sugar elongation reactions with glycosyl transferases such as GlcNAc beta 1,4-galactosyl transferase, beta Gal1-->3/4GlcNAc alpha-2,6-sialyl transferase, and beta Gal1-->3/4GlcNAc alpha-2,3-sialyl transferase in the presence of each sugar nucleotide as glycosyl donor to afford polymers having N-acetyllactosamine, sialyl alpha-(2-->6) N-acetyllactosamine, and sialyl alpha-(2-->3) lactose residues in excellent yield. Subsequent hydrogenolysis, hydrolysis with alpha-chymotrypsin, or transglycosylation to ceramide with ceramide glycanase proceeds smoothly to give N-acetyllactosamine, a versatile sialyl alpha-(2-->6) N-acetyllactosamine derivative having a terminal amino group, and ganglioside GM3 in high yield.
