Abstract
The problems with platinum complexes are resistance and toxicity of anticancer therapy. The aim of current study is the comparison of the influence of chemical structure and mechanism of hydrolysis on pharmacological activity and toxicological profile of approved in platinum drugs: Cisplatin, Carboplatin, Oxaliplatin, Nedaplatin, Lobaplatin, Heptaplatin, Satraplatin. Hydrolysis of Carboplatin and Nedaplatin occurs by double step hydration, to obtain the same active products as with Cisplatin: diaqudiamine-platinum. The similarity in mechanisms of hydrolysis of Oxaliplatin, Lobaplatin Heptaplatin, and Satraplatin is that the first part of the hydrolysis corresponds to the ring-opening and addition of the first water molecule, and in the second step of reaction occur the loss of the ligand and the formation of the di-aquated product by the addition of a second water molecule. Cisplatin, Carboplatin, and Oxaliplatin are nephrotoxic. Cisplatin and Heptaplatin are nephrotoxic. The similar dose-limiting effects of Carboplatin, Oxaliplatin, Nedaplatin, Lobaplatin, and Satraplatin is myelosuppression.
