topoisomerase II inhibitory activity. Compounds 7, 8, 11, 12, 13, and 22 with 2-furyl, 2-thienyl or 3-thienyl at 2-position of central pyridine showed the significant or moderate topoisomerase I inhibitory activity. Especially, compound 12 with strong topoisomerase II inhibitory activity at 100 μM and 20 μM, and moderate topoisomerase I inhibitory activity displayed strong cytotoxicity against several
为了开发潜在的抗癌药,我们设计和合成了30种新的2,4-二芳基-5 H-茚并[1,2- b ]吡啶衍生物,其在2-和-3处含有芳基部分,例如呋喃基,噻吩基,吡啶基和苯基。 5 H-茚并[1,2- b ]吡啶的4位。他们评估了拓扑异构酶I和II的抑制活性,以及对几种人类癌细胞系的细胞毒性。中制备的30种化合物,7,8,9,10,12,14,16,19,20,22,和23在中央吡啶的2-或4-位上的2-或3-呋喃基和/或2-或3-噻吩基具有明显或中等的拓扑异构酶II抑制活性。化合物7,8,11,12,13,和22与2-呋喃基,2-噻吩基或在中央吡啶2-位3-噻吩基显示显著或中度拓扑异构酶I抑制活性。尤其是,化合物12在100μM和20μM时具有强大的拓扑异构酶II抑制活性,而中等的拓扑异构酶I抑制活性则表现出对几种人类癌细胞系的强大细胞毒性。
