preparation of 1,4-dideoxy-1,4-imino-L-arabinitol derivatives carrying a propargyl group by way of the addition of TMS-propargyl Grignard reagent to a N-sulfinylglycosylamine is reported. This compound was coupled via a triazole-tether to various aromatic and heteroaromatic groups, thus providing structures that can be considered as simplified mimics of UDP-Galf, the substrate of GlfT2, a galactofuranosyltransferase
据报道,通过将 TMS-炔丙基格利雅试剂添加到 N-亚磺酰基糖胺中,可以方便地制备带有炔丙基的 1,4-二脱氧-1,4-亚氨基-L-阿拉伯糖醇衍生物。该化合物通过三唑系链与各种芳香族和杂芳香族基团偶联,从而提供了可被视为 UDP-Galf(分枝杆菌中存在的呋喃半乳糖基转移酶 GlfT2 的底物)的简化模拟物的结构。这些新化合物被评估为该酶的抑制剂,并发现尽管母体糖核苷酸中不存在二磷酸键,但仍具有显着的活性(IC50 值在高 M 到低 mM 范围内)。
