title: Anticancer cytotoxicity and nephrotoxicity of the new platinum (II) complexes containing diaminocyclohexane and glycolic acid.
abstract: Cisplatin is an important antineoplastic agent, but dose-limiting nephrotoxicity prevents potential efficacy. There is interest in developing new platinum agents that have less toxicity. We have synthesized novel platinum (II) coordination complexes containing diaminocyclohexane as carrier ligands, and glycolic acid as a leaving group. In this study, new platinum (II) complex compounds were evaluated for cytotoxicity on cancer cell lines and nephrotoxicity. The new platinum complexes have demonstrated high efficacy in the cytotoxicity against human ovarian adenocarcinoma cell lines (SKOV-3/NIH.OVCAR-3) and human prostate carcinoma cell lines (DU-145/PC-3). The cytotoxicity of these compounds against rabbit proximal renal tubular cells and human renal cortical tissues was determined by MTT assay, the [3H]-thymidine uptake and glucose consumption test, and found to be considerably less than those of cisplatin. Based on our results, these novel platinum compounds appear to be valuable lead compounds with high efficacy and low nephrotoxicity.
