  • Transition metal porphyrin complexes and methods of treatment using same
    Patent number: 9364537
    Abstract: A porphyrin of general formula (I) having a transition metal (II) cation in its core and one or two mono-, di-, tri-, tetra- or penta-halophenyl groups and two or three pyridyl groups in the 5, 10, and/or 15 positions of the porphyrin ring contributing to a positive two or three charge neutralized by the presence of a respective number of anions. The porphyrin of the general formula (I) characterized by killing pseudomonas bacteria in the dark.

  • Supramolecular complexes as photoactivated DNA cleavage agents
    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.
    Type: Grant
