Design and synthesis of metal-based chemotherapeutic agents for targeted DNA interactions or DNA repair pathway modulation
The research presented in this thesis explores the chemotherapeutic potential of metal-based compounds as chemotherapy agents, with an initial focus on the synthesis and DNA interaction studies of platinum and palladium compounds utilizing the [Pt(bapbpy)]2+ scaffold. The study identifies intercalation as the primary mechanism of action for these complexes. Furthermore, it provides a detailed structure-activity relationship analysis, highlighting the critical role of the complex's protonation state in influencing its biological activity and efficacy.

Subsequently, the study delves into photoactivated chemotherapy (PACT) using ruthenium (II) complexes, where light activation of ruthenium complexes enables targeted drug delivery to tumor cells, thereby reducing adverse effects. This research emphasizes the development of ruthenium-based compounds that can photorelease a DNA repair inhibitor, specifically targeting the RAD51 protein, essential for Homologous Recombination (HR). By disrupting the DNA repair mechanisms in cancer cells, this approach seeks to enhance the cytotoxicity of the therapy and address drug resistance.
