Rhodamine-modified fluorescent half-sandwich iridium and ruthenium complexes: potential application as bioimaging and anticancer agents

摘要

Most half-sandwich metal anticancer complexes are non-fluorescent, which results in an uncertain mechanism of action (MoA). We designed and synthesized eight fluorescent half-sandwich iridium (Ir) and ruthenium (Ru) complexes by introducing rhodamine derivatives into the N<^>N-chelating ligand. These complexes have features of bio-imaging and anticancer agents and may merit future development as novel anticancer agents.
