Bioavailability And Modes Of Action Of Novel Metal Based Phenanthroline Drugs, Tadhg O’Leary
Doctoral
Metal-basedcompounds have been utilised as chemotherapeutic agents for the last four decades due to their well-documented and clinically relevant anti-tumour properties.Acquired resistance is a challenge for the clinical use of these compounds and there is a continuing need to search for potential new therapeutic agents. Herein, the potential of two metal-basedcompounds containing chelated1,10-phenanthroline (1,10-Phen), one manganese-based (CMPD 73)andonecopper-based (CMPD 74), to act as novel therapeutic agents is explored.CMPD 73 displayed high micromolar (IC50>100μM) cytotoxic properties againstvarious cell systems but interestingly displayed increased cytotoxicity against ovarian (A2780), lung (A549) and cisplatin resistant mesothelioma cells(IC5040-50μM). CMPD 74 was equally cytotoxic against …
