lorophenyl pyridine compounds were synthesized and evaluated for cytotoxicity against four different human cancer cell lines (DU145, HCT15, T47D, and HeLa), and topoisomerase I and II inhibitory activity. Several compounds (10–15, 20, 22, 24, 28, 42, and 49) displayed strong to moderate dual topoisomerase I and II inhibitory activity at 100 μM. It was observed that hydroxyl and chlorine moiety at meta
为了不断开发新型抗肿瘤药,我们合成了一系列新的四十五种2-苯酚-4-芳基-6-氯苯基吡啶化合物,并评估了其对四种不同的人类癌细胞系(DU145,HCT15,T47D,和HeLa),以及拓扑异构酶I和II的抑制活性。几种化合物(10 - 15,20,22,24,28,42,和49)表现出强烈的,中度双拓扑异构酶I,并在100μMII抑制活性。观察到间位或对位的羟基和氯部分苯环的位置有利于双重拓扑异构酶的抑制活性和细胞毒性。与所有针对HCT15和T47D细胞系的阳性对照相比,大多数化合物显示出更强的细胞毒性。为了研究结构-活性关系,进行了使用比较分子场分析(CoMFA)方法的3D-QSAR分析。生成的3D等高线图可用于进一步合理设计新型三联吡啶衍生物,作为高度选择性和有效的细胞毒剂。
