  • Cryptate compounds and methods for diagnosis and therapy
    Patent number: 6869589
    Abstract: The present invention relates to cryptate compounds useful as chelating agents. In particular, the present invention relates to functionalized derivatives of certain cryptate compounds. These functionalized derivatives are suitable for use in radiolabelling and similar applications. The present invention also relates to a method for diagnosis or therapy of a disease utilizing functionalized derivatives of cryptase compounds.

  • Metal cage complexes and production thereof
    Patent number: 4497737
    Abstract: Hydrogen peroxide is produced by oxidation of a coordination complex of a metal ion capable of existing in at least two oxidation states and a ligand, the coordination complex being sufficiently stable for the metal ion to be oxidized and reduced without decomposition of the complex and the metal ion being in its lower oxidation state. In a cyclic process, the step of reduction of the complex with the metal ion in its higher oxidation state precedes the oxidation step, and the reduction and oxidation steps are repeated sequentially. Novel coordination complexes which may be used in the process have the formula: ##STR1## in which n represents an integer; M represents a cobalt ion or other metal ion having at least two oxidation states; x and y, which may be the same or different, each represent .tbd.N, .tbd.P or .tbd.
