A series of 2,4,6-tripyridyl pyridines were synthesized, and evaluated for their antitumor cytotoxicity, topoisomerase I and II inhibitory activity. From the eighteen prepared compounds, compounds 10-12 have shown better or similar cytotoxicity against several human cancer cell lines as compared to 2,2':6',2"-terpyridine and doxorubicin. Especially, compound 10 exhibited the most potent cytotoxicity better than positive controls. Structure-activity relationship study indicated that 2,2':6',2"-terpyridine skeleton has an important role in displaying significant cytotoxicity against several human cancer cell lines.
合成了一系列 2,4,6-三吡啶基吡啶,并对其抗肿瘤细胞毒性、拓扑异构酶 I 和 II 抑制活性进行了评估。与 2,2':6',2"-三吡啶和多柔比星相比,18 个制备的化合物中,化合物 10-12 对几种人类癌细胞株具有更好或相似的细胞毒性。其中,化合物 10 的细胞毒性最强,优于阳性对照。结构-活性关系研究表明,2,2':6',2"-三联吡啶骨架在对几种人类癌细胞系产生显著的细胞毒性方面起着重要作用。
