The anti-apoptotic Bcl-2 proteins are attractive targets for anti-cancer drug development, and the discovery of their selective inhibitors has become a research focus. In this Letter, obvious differences in the P1 pocket of the active site between Bcl-2, Bcl-xL, and Mcl-1 proteins were proposed by the structural comparison of these proteins. As a result, the groups in their inhibitors binding to the P1
抗凋亡的Bcl-2蛋白是抗癌药物开发的有吸引力的目标,其选择性抑制剂的发现已成为研究的重点。在这封信中,Bcl-2,Bcl-x L和Mcl-1蛋白在活性位点的P1口袋中存在明显差异,这是通过对这些蛋白的结构比较提出的。结果,其抑制剂中与P1口袋结合的基团可能对这些蛋白质的选择性产生重大影响。基于该假设,设计了前导化合物B-1的五种类型的衍生物,以及几种Bcl-x L(E-1)或Mcl-1蛋白(G) 被发现。本信中发现的Mcl-1蛋白选择性抑制剂为新型抗肿瘤药的开发提供了新的结构类型。
