A series of 3-aryl-4-indolylmaleimide IDH1/R132H inhibitors with a novel structure was obtained by high-throughput screening and structure-based optimization. Most compounds such as 7a, 7d, 7h, 7i, 7k and 7o showed high inhibitory effects on IDH1/R132H and were highly selective against IDH1/WT, IDH2/WT, GDH, GK, and FBP. Evaluation of the biological activities and function at cellular level showed
通过高通量筛选和基于结构的优化,获得了一系列具有新颖结构的3-芳基-4-吲哚基马来酰亚胺IDH1 / R132H抑制剂。大多数化合物(例如7a,7d,7h,7i,7k和7o)对IDH1 / R132H表现出高抑制作用,并且对IDH1 / WT,IDH2 / WT,GDH,GK和FBP具有高度选择性。在细胞水平上对生物学活性和功能的评价表明,化合物7h,7i和7k可以有效抑制表达IDH1 / R132H的U87MG细胞中2-羟基戊二酸的产生。此外,IDH1 / R132H的过表达可能会导致7h逆转髓样白血病细胞系TF-1的分化阻滞。我们还根据实验数据探索了结构-活性关系,以期为将来的研究铺平道路。
