Designed and synthesized twenty-four 2,4-diaryl benzofuro[3,2-b]pyridine derivatives were evaluated for topoisomerase I and II inhibitory activities as well as cytotoxicities against several human cancer cell lines. Various aryl groups such as phenyl, 2- or 3- furyl, 2- or 3-thienyl, and 2-pyridyl were substituted at 2- or 4- position of central pyridine. Compounds 8, 12, 13, and 14, with 2-furyl either
对设计和合成的 24 种 2,4-二芳基苯并呋喃 [3,2-b] 吡啶衍生物的拓扑异构酶 I 和 II 抑制活性以及对几种人类癌细胞系的细胞毒性进行了评估。各种芳基如苯基、2-或3-呋喃基、2-或3-噻吩基和2-吡啶基在中心吡啶的2-或4-位被取代。化合物 8、12、13 和 14,在中心吡啶的 2 位或 4 位具有 2-呋喃基,在 100°C 时显示出显着的拓扑异构酶 II 抑制活性。
