A series of new (Z)-3-(3′-methoxy-4′-(2-amino-2-oxoethoxy)benzylidene)indolin-2-one derivatives has been synthesized and evaluated for their cytotoxic activity against selected human cancer cell lines of prostate (PC-3 and DU-145), breast (BT-549 and MDA-MB-231) and non-tumorigenic prostate epithelial cells (RWPE-1). Among the tested, one of the compounds 4p exhibited potent cytotoxicity selectively on prostate cancer cell lines (PC-3 and DU-145; IC50: 1.89 ± 0.6 and 1.94 ± 0.2 μM, respectively). Further experiments were conducted with 4p on PC-3 cancer cells to study the mechanisms of growth inhibition and apoptosis inducing effect. Treatment of PC-3 cells with test compound 4p resulted in inhibition of cell migration through disorganization of F-actin protein. The flow-cytometry analysis results showed that the compound arrested PC-3 cancer cells in the G2/M phase of cell cycle in a dose dependent manner. Hoechst staining and annexin-V binding assay revealed that the compound 4p inhibited tumor cell proliferation through induction of apoptosis. Western blot studies demonstrated that the compound 4p treatment led to activation of caspase-3, increased expression of pro-apoptotic Bax and significantly decreased expression of anti-apoptotic Bcl-2 in human prostate cancer PC-3 cells. In addition, the mitochondrial membrane potential (ΔΦm) was also affected and the levels of intracellular Ca2+ were raised.
