Abstract
Although chemotherapy has increased the life expectancy of cancer patients, its toxic side effects remain a major challenge. Recently, organometallic compounds, such as Schiff base copper complexes, have become promising candidates for next-generation anticancer drugs owing to their unique anticancer activities. In this study, binuclear copper(II) complex-1 and mononuclear copper(II) complex-2 were examined to analyze their anticancer mechanisms further. For this purpose, a viability test, flow cytometry analysis of apoptosis and the cell cycle, migration assay, and gene expression analysis were performed. According to our results, complex-1 was more cytotoxic than complex-2 at 24/48-h intervals. Our findings also demonstrated that both complexes induced apoptosis at IC50 concentrations and arrested the cell cycle at the G1-S checkpoint. However, complex-1 accelerates cell cycle arrest at the sub-G0/G1 phase more than complex-2 does. Furthermore, gene expression analysis showed that only complex-1 induces the expression of p53. Interestingly, both complexes induced Bcl-2 overexpression. However, they did not affect MMP-13 expression. More interestingly, both complexes inhibited cell migration in different ways, including amoeboid and collective, by recruiting protease-independent pathways. This study confirmed that adding several metal cores and co-ligands increased the activity of the complex. It also appeared that Cu-containing complexes could prevent the migration of cancer cells through protease-independent pathways, which can be used for novel therapeutic purposes.
