Abstract

A series of 2-(thienyl-2-yl or -3-yl)-4-furyl-6-aryl pyridine derivatives were designed, synthesized, and evaluated for their topoisomerase I and II inhibition and cytotoxic activity against several human cancer cell lines. Compounds 10-19 showed moderate topoisomerase I and II inhibitory activity and 20-29 showed significant topoisomerase II inhibitory activity. Structure-activity relationship study revealed that 4-(5-chlorofuran-2-yl)-2-(thiophen-3-yl) moiety has an important role in displaying topoisomerase II inhibition.

摘要

设计、合成了一系列 2-(噻吩-2-基或-3-基)-4-呋喃基-6-芳基吡啶衍生物,并对它们的拓扑异构酶 I 和 II 抑制活性以及对几种人癌细胞系的细胞毒性进行了评价。化合物 10-19 表现出中等的拓扑异构酶 I 和 II 抑制活性,而化合物 20-29 表现出显著的拓扑异构酶 II 抑制活性。构效关系研究表明,4-(5-氯呋喃-2-基)-2-(噻吩-3-基)部分在显示拓扑异构酶 II 抑制方面具有重要作用。
