In an effort to develop potent anti-cancer chemopreventive agents that act on topoisomerase II, a novel series of bisindolylalkanes analogues such as 3,3′-(thiochroman-4,4-diyl)bis(1H-indole) are synthesized. Structures of all compounds are elucidated by 1H NMR, 13C NMR and HRMS. Anti-proliferative activities for all of these compounds are investigated by the method of MTT assay on 7 human cancer lines
为了努力开发作用于拓扑异构酶II的有效的抗癌化学预防剂,合成了一系列新的双吲哚基烷烃类似物,例如3,3'-(thiochroman-4,4-diyl)bis(1 H-吲哚)。通过1 H NMR,13 C NMR和HRMS阐明所有化合物的结构。通过MTT测定法对7种人类癌症细胞系研究了所有这些化合物的抗增殖活性。它们中的大多数在体外均显示出抗肿瘤活性,对MCF7的半数最大抑制浓度(IC 50)值为3.798μg/ mL的3a。化合物3a在100μM浓度下显示出与依托泊苷(VP-16)相当的拓扑异构酶II抑制活性。其余化合物还显示出不同程度的拓扑异构酶II抑制活性。
