and silver sulfadiazine. Furthermore, the growth inhibitory effects of 1-4 on four human cancer cell lines (MCF-7, PC-3, A549 and HT-29) showed that 4 has a potent cytotoxic activity against MCF-7 cells, significantly higher than cisplatin and carboplatin. The effects of the complexes on the inhibition of the cells are closely related to their lipophilicity as well as DNA/protein binding. The induction of apoptosis of MCF-7 cells treated with 4 was probed through Hoechst 33342 staining, Annexin V positivity and caspase 3/7 activity. In addition, increased ROS levels in the presence of 4 are most likely responsible for damage to both mitochondria and genomic DNA.
