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 that compounds 7h, 7i and 7k could effectively suppress the production of 2-hydroxyglutaric acid in U87MG cells expressing IDH1/R132H. Additionally, 7h could reversed the differentiation block of the myeloid leukemic cell line, TF-1, caused by the overexpression of IDH1/R132H. We also explore the structure-activity relationship based on the experimental data, with an attempt to pave the way for future studies.
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，如 7a、7d、7h、7i、7k 和 7o，对 IDH1/R132H 具有高抑制作用，并且对 IDH1/WT、IDH2/WT、GDH、GK 和 FBP 具有高度选择性。在细胞水平上评估生物活性和功能的结果表明，化合物 7h、7i 和 7k 能够有效抑制表达 IDH1/R132H 的 U87MG 细胞中 2-羟基戊二酸的产生。此外，7h 能够逆转由于 IDH1/R132H 过表达而导致的髓样白血病细胞系 TF-1 的分化阻滞。我们还根据实验数据探索了构效关系，以期为未来的研究铺平道路。
