Tyrosyl-DNA phosphodiesterase I (Tdp1) plays a key role in the repair of damaged DNA resulting from the topoisomerase I (Top1) inhibitor camptothecin and a variety of other DNA-damaging anticancer agents. This report documents the design, synthesis, and evaluation of new indenoisoquinolines that are dual inhibitors of both Tdp1 and Top1. Enzyme inhibitory data and cytotoxicity data from human cancer
酪氨酰 DNA 磷酸二酯酶 I (Tdp1) 在修复由拓扑异构酶 I (Top1) 抑制剂喜树碱和多种其他破坏 DNA 的抗癌剂引起的受损 DNA 中发挥关键作用。本报告记录了作为 Tdp1 和 Top1 双重抑制剂的新型茚并异喹啉的设计、合成和评估。来自人类癌细胞培养物的酶抑制数据和细胞毒性数据用于建立结构-活性关系。茚并异喹啉对 Tdp1 的效力范围为 5 μM 到 111 μM,这使得活性更强的化合物成为已知的最有效的该靶标抑制剂。细胞毒性平均图中点范围为 0.02 至 2.34 μM。
