Substances with dual tyrosyl-DNA phosphodiesterase I–topoisomerase I inhibitory activity in one low molecular weight compound would constitute a unique class of anticancer agents that could potentially have significant advantages over drugs that work against the individual enzymes. The present study demonstrates the successful synthesis and evaluation of the first dual Top1–Tdp1 inhibitors, which are based
在一种低分子量化合物中具有双重酪氨酰-DNA 磷酸二酯酶 I-拓扑异构酶 I 抑制活性的物质将构成一类独特的抗癌剂,可能比针对单个酶的药物具有显着的优势。本研究证明了基于茚并异喹啉化学型的第一个双 Top1-Tdp1 抑制剂的成功合成和评估。一种双(茚并异喹啉)对人 Tdp1 具有显着活性(IC 50= 1.52 ± 0.05 μM),并且作为 Top1 抑制剂与喜树碱等效。通过该系列的结构-活性关系研究,获得了对酶-药物相互作用的重要见解。目前的结果还证明了先前报道的磺酰酯药效团未能在这种茚并异喹啉类抑制剂中赋予 Tdp1 抑制作用,尽管它被证明对类固醇 NSC 88915 有效 ( 7 )。目前的研究将促进未来优化双 Top1-Tdp1 抑制剂的努力。
