The synthesis of a series of aryl-substituted cyclic sugar imines was performed via a tandem nucleophilic addition/substitution reaction. The so-obtained ketimines displayed fucosidase inhibitory activities (IC50 = 46–556 μM). Their reduced counterparts were prepared and assayed after addition of sodium borohydride to the enzymatic assay stock solution. The pyrrolidines strongly inhibit fucosidase
通过串联亲核加成/取代反应进行一系列芳基取代的环状糖亚胺的合成。如此获得的酮亚胺显示岩藻糖苷酶抑制活性(IC 50 = 46–556μM)。在将硼氢化钠添加到酶法测定储备液中后,制备并测定其还原的对应物。吡咯烷强烈抑制岩藻糖苷酶(IC 50 = 0.65–150μM)。
