Abstract

Cisplatin is one of the most active chemotherapeutic agents used in the treatment of childhood and adult malignancies. Cisplatin induces cell death through different pathways. Despite its effectiveness, the continued clinical use of cisplatin is limited by onset of severe side effects (nephrotoxicity, ototoxicity and neurotoxicity) and drug resistance. Therefore, one of the main experimental oncology purpose is related to the search for new platinum-based drugs to create different types of adducts or more specific and effective subcellular targets. Thus, [Pt(O,O'-acac)(γ-acac)(DMS)], which reacts preferentially with protein thiols or thioether, was synthesized. In our research, different approaches were used to compare cisplatin and [Pt(O,O'-acac)(γ-acac)(DMS)] effects in B50 rat neuroblastoma cells. Our results, using immunocytochemical, cytometric and morphological techniques, showed that these compounds exert a cytostatic action and activate apoptosis with different pathways. Long-term effects demonstrated that [Pt(O,O'-acac)(γ-acac)(DMS)] exerts cytotoxic effects in neuronal B50 cell line not inducing drug resistance. Analysis was performed both to compare the ability of these platinum compounds to induce cell death and to investigate the intracellular mechanisms at the basis of their cytotoxicity.
