  • Macromolecular carrier for drug and diagnostic agent delivery
    Patent number: 6409990
    Abstract: New macromolecular carriers for drugs and diagnostic agents are described that make use of the chemical attachment of new leashes to oligomeric backbone structures. The synthesis of these leashes and their facile creation, reaction and conjugation with chelators and ligands makes them ideal candidates for use in medicine, and especially diagnostics.

  • Radiolabeled neoglycopeptides
    Patent number: 4401647
    Abstract: Radiopharmaceuticals and method are provided for scintigraphic evaluation of the liver. The radiopharmaceuticals comprise a radionuclide (technetium) labeled neoglycoprotein which provides for specific binding of the radiopharmaceutical to hepatocytes and allows for accurate determination of rates of binding and release of Tc-99m to and from the liver. The observed rates may then be used to determine diseased states, conveniently using an appropriate algorithm for the calculation.
