series of ten glycosyltransferase inhibitors has been designed and synthesized by using pyridine as a pyrophosphate surrogate. The series was prepared by conjugation of carbohydrate, pyridine, and nucleoside building blocks by using a combination of glycosylation, the Staudinger–Vilarrasa amide‐bond formation, and azide–alkyne click chemistry. The compounds were evaluated as inhibitors of five metal‐dependent
通过使用吡啶作为焦磷酸盐替代物,已经设计并合成了一系列十种糖基转移酶抑制剂。该系列是通过结合糖基化,Staudinger-Vilarrasa酰胺键形成和叠氮化物-炔烃点击化学反应,结合碳水化合物,吡啶和核苷结构单元而制备的。该化合物被评估为五种金属依赖性半乳糖基转移酶的抑制剂。三种酶在一种酶的活性位点复合的抑制剂的晶体学分析证实,吡啶部分螯合了Mn 2+离子,导致其原始位置略微移位(2Å)。与天然尿苷二磷酸(UDP)-Gal底物相比,碳水化合物的头基占据的位置不同,与酶的相互作用很小。
