  Chemoenzymatic Synthesis of Neoglycopeptides:  Application to an α-Gal-Terminated Neoglycopeptide

  摘要：

  A novel methodology; for the enzymatic preparation from suitably derivatized oligosaccharides of N-linked neoglycopeptides using the microbial glutaminyl-peptide gamma -glutamyl transferase, transglutaminase (TGase), is described, N-Allyl glycosides of various oligosaccharides were photochemically coupled with cysteamine to yield amino-terminated thioether spacers, which were accepted by transglutaminase to transamidate the side-chain gamma -carboxamide group in the dipeptide Z-Gln-Gly.
