In order to develop potent anticaner agents, a novel series of 3-(1H-indol-3-yl)-2,3,3a,4-tetrahydrothiochromeno[4,3-c]pyrazole derivatives were synthesized. Structures of all compounds were confirmed. MTT assay has been employed to study antiproliferative activity of these compounds with four human cancer cell lines (MGC-803, Hela, MCF-7 and Bel-7404) and a normal cell line L929. Most of these compounds
为了开发有效的抗癌剂,合成了一系列新的3-(1 H-吲哚-3-基)-2,3,3a,4-四氢硫代色素[4,3-c]吡唑衍生物。确认所有化合物的结构。MTT分析已用于研究这些化合物对四种人类癌细胞系(MGC-803,Hela,MCF-7和Bel-7404)和正常细胞系L929的抗增殖活性。这些化合物大多数在体外对正常细胞表现出潜在的抗癌活性和低细胞毒性。7d和7f显示出最佳的抗癌活性,其IC 50MGC-803的最大值分别为15.43μM和20.54μM。他们大多数表现出拓扑异构酶II选择性抑制。裂解反应分析和DNA解链分析表明7f为非嵌入的Topo II催化抑制剂,与对接结果一致。激光扫描共聚焦显微镜系统跟踪可以大量进入细胞核的代表性化合物7d和7f的位置。特别地,最有效的化合物7d和7f显示出能够诱导MGC-803细胞中的G2 / M细胞周期停滞和凋亡。
