Abstract Ruthenium compounds have received great attention in the field of metallodrugs because of their potential as anticancer agents. Complexes containing Ru2(II,III) dimetal cores coordinated to Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) developed in our research group have shown promising results in studies in vitro and in vivo in glioma models, such as the glioblastoma multiforme, a highly malignant brain cancer. The main objectives of this project are to study the interactions of Ru2(II,III)-NSAID complexes with aminopyridines and to investigate the feasibility of developing hybrid nanoparticle systems that can promote loading and sustained release of the metallodrugs. Lipid nanoparticles are capable of crossing the blood brain barrier and are promising for the treatment of gliomas, allowing, among other things, to increase the intracellular and intratumoral bioavailability and to lower the systemic toxicity of antitumor drugs. The main goals of the research plan are: 1) to prepare ruthenium-NSAID complexes, in particular NSAID = ibuprofen, and to investigate their interaction with 4-aminopyridine to try to prepare new mixed derivatives; 2) to perform tests of partition of the studied complexes in some saturated and unsaturated lipids to select the most appropriate lipids; 3) to develop methodology for preparation of lipid nanoparticles containing the metallodrugs; 4) to characterize the complexes and the materials obtained by means of several techniques; 5) to investigate the feasibility of releasing the metallodrugs from the hybrid materials; 6) to establish collaborations to conduct studies in vitro and/or in vivo in order to verify the potential application of the systems in anticancer treatments.
