Gliomas are the most frequent primary tumours of the nervous system, characterised by high degree of malignancy, widespread invasion and high-rate proliferation. Cisplatin and analogue are currently employed in clinical trials as active chemotherapeutic agents for the systemic treatment of this type of malignancy. Despite therapy benefits, clinical use of these agents is hampered by severe side effects including neurotoxicity. Therefore, the aim of the present study was to analyse the effect of a new compound of platinum(IV) conjugate, named Pt(IV)Ac-POA, which can generate a synergistic antineoplastic action when released along with cisplatin, after a specific reduction reaction within tumour cells. To assess the effects of the novel compound on rat C6 glioma cells, cell cycle and cell death activation analyses were carried out using flow cytometry. Morphological changes and activation of different cell death pathways were evaluated by both transmission electron microscopy and immunofluorescence microscopy. Protein expression was investigated by western blotting analysis. The novel compound Pt(IV)Ac-POA, bearing as axial ligand (2-propynyl)octanoic acid (POA), which is a histone deacetylase inhibitor (HDACi), acts as a prodrug in tumour cells, inducing cell death through different pathways at a concentration lower than those tested for other platinum analogues. The current results showed that Pt(IV)Ac-POA could represent a promising improvement of Pt-based chemotherapy against gliomas, either inducing a chemosensitisation and reducing chemoresistance.
