Abstract
Abstract To date, numerous platinum (II) complexes have been successfully used in the treatment of different types of cancer. Therapeutic platinum complexes are different in terms of their structure, chemical reactivity, solubility, pharmacokinetics and toxicity. The aim of our research was the evaluation of cardiotoxicity of dichloro-(ethylendiamine) platinum (II) in a model of isolated rat heart using the Langedorff technique. Oxidative stress was assessed by determination of superoxide anion radical, hydrogen peroxide, Thiobarbituric Acid Reactive Substances and nitric oxide levels from coronary venous effluent. All reagents were perfused at increasing concentrations from 10-8 to 10-4 M for 30 minutes. In this paper, we report that substances administered at higher doses did not induce dose-dependent effects on oxidative stress markers. The results of this research may be of great interest for future studies in this area. There are many novel platinum compounds that had previously demonstrated antitumour activity, and these types of experiments in our study can assist in the examination of their cardiotoxicity. These results could be helpful for understanding dose-dependent side effects of existing and novel platinum compounds
