Abstract

The three disaccharides, 4-O-beta-D-glucopyranosyl-6-deoxy-D-glucose (Glc-6-deoxy-Glc), 4-O-beta-D-glucopyranosyl-D-mannosamine (Glc-ManN), 4-O-beta-D-glucopyranosyl-D-mannose (Glc-Man), were synthesized from equimolar amounts of 6-deoxy-glucose and alpha-D-glucose-1-phosphate (G-1-P), D-mannosamine and alpha-D-glucose-1-phosphate (G-1-P), and D-mannose and alpha-D-glucose-1-phosphate (G-1-P), respectively, using cellobiose phosphorylase from Cellvibrio gilvus. The yields were 60%, 10% and 50% based on the initial amounts of 6-deoxy-D-glucose, D-mannosamine and D-mannose, respectively. The structures of disaccharides were confirmed by NMR and mass spectroscopy analysis.

摘要

三种二糖,4-O-β-D-吡喃葡萄糖基-6-脱氧-D-葡萄糖(Glc-6-脱氧-Glc)、4-O-β-D-吡喃葡萄糖基-D-甘露糖胺(Glc-ManN)、4-O-β-D-吡喃葡萄糖基-D-甘露糖(Glc-Man),分别由等摩尔量的6-脱氧葡萄糖与α-D-葡萄糖-1-磷酸(G-1-P)、D-甘露糖胺与α-D-葡萄糖-1-磷酸(G-1-P)、D-甘露糖与α-D-葡萄糖-1-磷酸(G-1-P),使用来自吉尔维氏纤维弧菌的纤维二糖磷酸化酶合成。基于6-脱氧-D-葡萄糖、D-甘露糖胺和D-甘露糖的初始量,产率分别为60%、10%和50%。二糖的结构通过核磁共振和质谱分析得以确认。
