Trihydroxy-2-thiaquinolizidines, a new class of bicyclic dideoxy-iminohexitol glycosidase inhibitor derivatives with nominally the d-gluco, l-ido, d-manno and l-gulo configurations were synthesized. X-ray analyses indicated that the preferred conformation for d-gluco and d-manno derivatives was a flat trans-fused system. Unlike deoxynojirimycin, the compound with d-gluco configuration was selective
合成了三羟基-2-硫代喹唑烷类,这是一类新型的双环双脱氧亚氨基己糖醇糖苷酶抑制剂衍生物,具有名义上的d-葡萄糖,l- ido,d- manno和l-gulo构型。透视分析表明,对于D-优选构象葡萄糖和D-甘露糖的衍生物是一个扁平的反式-融合系统。不像脱氧野尻霉素,用D-的化合物葡糖配置是有选择性的α葡糖苷酶(酵母和米),并没有显示出向β葡糖苷酶(杏仁),α半乳糖苷酶(生咖啡豆),α半乳糖苷酶(抑制活性Ë。大肠杆菌)和α-甘露糖苷酶(千斤顶豆),而ido衍生物对β-葡萄糖苷酶(杏仁)具有特异性。
