Methyl oligobiosaminide (1) the core structure of oligostatin C, and five analogues, the 6-hydroxy-(2), 2-deoxy- (3), 2-deoxy-6-hydroxy- (4), 3-deoxy- (5), and 3-deoxy-6-hydroxy derivatives (6), were synthesized by coupling the protected pseudo-sugar epoxide 46 with suitable methyl 4-amino-4-deoxy-alpha-D-hexopyranoside derivatives. Compounds 3 and 6 showed notable inhibitory activity against alpha-D-glucosidase
甲基oligobiosaminide(1)的核心结构是oligostatin C和5个类似物,即6-羟基-(2),2-脱氧-(3),2-脱氧-6-羟基-(4),3-脱氧-( 5)和3-脱氧-6-羟基衍生物(6)是通过将保护的假糖环氧化物46与合适的甲基4-氨基-4-脱氧-α-D-己吡喃糖苷衍生物偶联而合成的。化合物3和6分别显示出对α-D-葡糖苷酶和α-D-甘露糖苷酶的显着抑制活性,而化合物1几乎没有活性。
