Pyrrolidine‐based iminocyclitols are a promising class of glycosidase inhibitors. Reported herein is a convenient epimerization strategy that provides direct access to a range of stereoisomeric iminocyclitol inhibitors of O‐GlcNAcase (OGA), the enzyme responsible for catalyzing removal of O‐GlcNAc from nucleocytoplasmic proteins. Structural details regarding the binding of these inhibitors to a bacterial
基于吡咯烷的亚氨基环醇是一种有前途的糖苷酶抑制剂。本文报道了一种便捷的差向异构策略,可直接访问一系列O-GlcNAcase(OGA)的立体异构亚氨基环醇抑制剂,该酶负责催化从胞质蛋白中去除O-GlcNAc。关于这些抑制剂与OGA细菌同源物结合的结构细节揭示了效力的基础。这些化合物可以口服获得,并渗透到啮齿动物的大脑中以增加O-GlcNAc,并应被证明是研究OGA在健康和疾病中的作用的有用工具。
