pyruvate kinase is an emerging target for antitumor therapy. In this letter, we describe the discovery of 2-((1H-benzo[d]imidazol-1-yl)methyl)-4H-pyrido[1,2-a]pyrimidin-4-ones as potent and selective PKM2 activators which were found to have a novel binding mode. The original lead identified from high throughput screening was optimized into an efficient series via computer-aided structure-based drug design
丙酮酸激酶的M2同工型是抗肿瘤治疗的新兴目标。在这封信中,我们描述了发现2-((1 H-苯并[ d ]咪唑-1-基)甲基)-4 H-吡啶基[1,2- a ]嘧啶-4-酮的发现,这是有力且选择性的PKM2被发现具有新型结合模式的活化剂。通过计算机辅助基于结构的药物设计,将从高通量筛选中鉴定出的原始铅优化为有效系列。该系列中的代表性化合物和文献中描述的活化剂均被用作分子工具来探测PKM2活化对癌细胞的生物学作用。我们的结果表明,单独的PKM2激活不足以改变癌细胞的代谢。
