  • Patent number: 5756825
    Abstract: The present disclosure details the preparation of hydroxamic-acid based bifunctional chelators and their use in conjugating metal ions to proteins and nucleic acids for tumor or tissue imaging or therapy purposes. Some preferred aspects of the disclosure involve the preparation of trisuccin, chemical name N-?tris(2-N- benzyloxyaminocarbonylethyl)! methylsuccinamic acid, which is a hydroxamic acid/succinate based structure that is particularly useful for binding radionuclides such as .sup.99m Tc, .sup.186 Re and .sup.67 Cu.

  • Patent number: 5714631
    Abstract: A group of functionalized amine chelants having ortho ligating functionality that form complexes with rare-earth type metal ions are disclosed. The complexes can be covalently attached to an antibody or antibody fragment and used for therapeutic and/or diagnostic purposes. In addition certain of the chelant-radionuclide complexes can be effectively employed in compositions useful as therapeutic and/or diagnostic agents for calcific tumors and/or relief of bone pain.

  • Patent number: 5710282
    Abstract: The present invention provides a novel one-step process for preparing substituted aryls which can be used as end-capping monomers for preparing highly branched macromolecule polymers that have highly controlled molecular architectures. The process comprises the steps of (a) reacting an aromatic acid with an activating carbodiimide for a sufficient period of time and under suitable conditions of temperature and pressure to form an activated aromatic intermediate, and (b) reacting said intermediate with a suitable nucleophile for a sufficient period of time and under suitable conditions of temperature and pressure to form said substituted aryl compound.
