摘要：

In our previous studies, benzimidazole-oxindole conjugates were synthesized and evaluated by National Cancer Institute (NCI) for their cytotoxic activity and the new molecules like 5c and 5p were considered as potential leads. These conjugates arrested the cell cycle at G2/M phase and inhibited tubulin polymerization. These observations prompted us to investigate the apoptotic mechanism induced by these lead molecules against human breast cancer cells (MCF-7). Studies like measurement of mitochondrial membrane potential (Delta psi(m)), generation of reactive oxygen species (ROS) and Annexin V-FITC assay revealed that these compounds induced mitochondrial mediated (intrinsic apoptotic pathway) apoptosis in human breast cancer cells. It was further confirmed by western blot analysis of pro apoptotic protein Bax, anti apoptotic protein Bcl-2, cytochrome c release, caspase-9 activity and cleavage of PARP. (C) 2016 Elsevier Ltd.
