Background and Aims: Cisplatin is currently one of the most widely used anticancer drugs in the world. However, its clinical usefulness has frequently been limited by severe side effects, such as nephrotoxicity, ototoxicity and neurotoxicity. Therefore, platinum(II) oxalato complexes with substitute imidazole or benzimidazole carrier ligands were synthesized and their cytotoxic effects were investigated against non-small cell lung cancer (H1299) and human colon adenocarcinoma (CaCo-2), and mouse fibroblast cells lines (L929).Methods: Four platinum(II) complexes, [Pt(L1-L4)2(oxalate)] were synthesized and characterized by FT-IR, 1H NMR and elemental analyses. The MTT method was used to determine the potential antiproliferative effect of synthesized platinum(II) complexes and positive controls.Results: In this study, the cytotoxic activity of platinum(II) complexes against tested cell lines was assessed, with moderate IC50 values. According to IC50 values, Complex 5 with 2-ethylbenzimidazole ligand was found to be the most active complex against H1299 and CaCo-2 cell lines. In general, the compounds are also promising drug candidates for H1299 cell lines with very low activity against the CaCo-2 cell lines.Conclusion: Further modification and development of Complex 4 and 5 derivatives and in vitro cytotoxic activity studies against different cancer cell lines may lead to the emergence of new anticancer agents in the near future.
