Anti-apoptotic Bcl-2 family proteins are overexpressed in a wide spectrum of cancers and have become well validated therapeutic targets. Cancer cells display survival dependence on individual or subsets of anti-apoptotic proteins that could be effectively targeted by multimodal inhibitors. We designed a 2,5-substituted benzoic acid scaffold that displayed equipotent binding to Mcl-1 and Bfl-1. Structure-based
抗凋亡的Bcl-2家族蛋白在多种癌症中均过表达,并已成为公认的治疗靶标。癌细胞显示出对单个或部分抗凋亡蛋白的生存依赖性,而抗凋亡蛋白可以被多峰抑制剂有效靶向。我们设计了2,5-取代的苯甲酸支架,该支架表现出与Mcl-1和Bfl-1的等价结合。基于结构的设计受Mcl-1的几种共晶结构的指导,从而导致化合物24的开发,该化合物结合Mcl-1和Bfl-1的Ki值为100 nM,并显示出超过Bcl-2 / Bcl的选择性-xL。在模型淋巴瘤细胞系中,将24的选择性结合谱转化为靶细胞活性。
