  • Patent number: 8445475
    Abstract: The invention provides supramolecular metal complexes as DNA cleaving agents. In the complexes, charge is transferred from one light absorbing metal (e.g. Ru or Os) to an electron accepting metal (e.g. Rh) via a bridging ?-acceptor ligand. A bioactive metal-to-metal charge transfer state capable of cleaving DNA is thus generated. The complexes function when irradiated with low energy visible light with or without molecular oxygen.
