An expeditious microwave-assisted one-pot synthesis of new cytotoxic phenanthrene fused-tetrahydrodibenzo-acridinones has been successfully accomplished. This protocol offers wide substrate scope, catalyst-free synthesis, atom-economy, simple recrystallization, high yields, and ethanol was used as green solvent. These new compounds were tested for their in vitro cytotoxicity against cervical (HeLa)
一种新型新的细胞毒性菲稠合四氢二苯并ac啶酮的快速微波辅助一锅合成方法已经成功完成。该方案提供了广泛的底物范围,无催化剂合成,原子经济,简单的重结晶,高收率,并且乙醇被用作绿色溶剂。测试了这些新化合物对宫颈(HeLa),前列腺(PC-3),纤维肉瘤(HT-1080),卵巢癌(SKOV-3)癌细胞的体外细胞毒性,并且对正常(Hek-293T)肾脏的安全性更高细胞系。所有化合物均显示出显着的细胞毒性特征,其中8m是最有效的化合物,IC 50抗SKOV-3卵巢癌细胞的0.24±0.05μM。流式细胞仪分析显示细胞在细胞周期的G2 / M期被阻滞。还研究了8m对F-肌动蛋白聚合的影响。Hoechst染色清楚地表明,活细胞数量减少,并表明细胞凋亡进程。通过JC-1染色观察到,化合物8m导致线粒体膜电位下降,并且还增强了活性氧的生成。caspase-3激活的增加3.7倍支持强烈的细胞凋亡诱导。另外,用
