随着丝氨酸羟甲基转移酶(SHMT)是抗疟药的可治疗靶点的发现,这项研究的目的是在叶酸生物合成周期中设计该关键酶的新型抑制剂。本文报道了19种基于2-吲哚满酮或二氢茚骨架的新颖螺环配体,并具有吡唑并吡喃核心。测量了对恶性疟原虫(Pf)SHMT(14–76 n m)的强目标亲和力和低纳摩尔范围(165–334 n m)的细胞效能,以及对人胞质SHMT1(h SHMT1)的有趣选择性。间日疟原虫的四个共晶体结构(Pv)SHMT在2.2–2.4Å的分辨率下进行了分析,揭示了乙烯基氰胺对于将配体锚定在活性位点中的关键作用。分子中的螺环基序使吡唑并吡喃核心具有比以前的非螺环类似物更大的弯曲构象。最后,讨论了受体结合的配体的螺内酰胺环的溶剂化。

A highly efficient and sustainable catalytic Staudingerreduction for the conversion of organic azides to amines in excellent yields has been developed. The reaction displays excellent functional group tolerance to functionalities that are otherwise prone to reduction, such as sulfones, esters, amides, ketones, nitriles, alkenes, and benzyl ethers. The green nature of the reaction is exemplified by
