The cleavage of two sugar epoxides, methyl 2,3-anhydro-α-D-mannopyranoside and 2,3-anhydro-α-D-allopyranoside, with amines is presented as a method for preparing a library of 3-amino-sugars (methyl 3-amino-3-deoxy-α-D-altropyranosides and methyl 3-amino-3-deoxy-α-D-glucopyranosides) as potential glycosidase inhibitors. Several of the altropyranosides were micromolar inhibitors of bovine liver β-galactosidase and almond β-glucosidase. X-Ray crystal structures were determined for one of the methyl 3-amino-3-deoxy-α-D-altropyranosides, 4t, and one of the methyl 3-amino-3-deoxy-α-D-glucopyranosides, 6d.
用胺类对两种糖环氧化物(甲基2,3-氟代-α-D-甘露糖苷和2,3-氟代-α-D-阿洛糖苷)进行裂解,以准备一系列3-氨基糖(甲基3-氨基-3-脱氧-α-D-阿尔托糖苷和甲基3-氨基-3-脱氧-α-D-葡萄糖苷)作为潜在的糖苷酶抑制剂。几种阿尔托糖苷对牛肝β-半乳糖苷酶和杏仁β-葡萄糖苷酶表现出微摩尔级的抑制活性。对其中一种甲基3-氨基-3-脱氧-α-D-阿尔托糖苷(4t)和一种甲基3-氨基-3-脱氧-α-D-葡萄糖苷(6d)进行了X射线晶体结构的测定。
