  • Patent number: 9884132
    Abstract: The present invention provides bivalent and multivalent ligands with a view to improving the affinity and pharmacokinetic properties of a urea class of PSMA inhibitors. The compounds and their synthesis can be generalized to multivalent compounds of other target antigens. Because they present multiple copies of the pharmacophore, multivalent ligands can bind to receptors with high avidity and affinity, thereby serving as powerful inhibitors. The modular multivalent scaffolds of the present invention, in one or more embodiments, contains a lysine-based (?, ?-) dialkyne residue for incorporating two or more antigen binding moieties, such as PSMA binding Lys-Glu urea moieties, exploiting click chemistry and one or more additional lysine residues for subsequent modification with an imaging and/or therapeutic nuclides or a cytotoxic ligands for tumor cell killing.

  • Patent number: 9844598
    Abstract: Systemic administration of intact, bacterially derived minicells results in rapid accumulation of the minicells in the microenvironment of a brain tumor, in therapeutically significant concentrations, without requiring endothelial endocytosis/transcytosis across the blood brain barrier or any other mechanism by which, pursuant to conventional approaches, nanoparticles have entered into that microenvironment. Accordingly, a wide variety of brain tumors, both primary and metastatic, can be treated by administering systemically a therapeutically effective amount of a composition comprised of a plurality of such minicells, each minicell being a vehicle for an active agent against the tumor, such as a radionuclide, a functional nucleic acid or a plasmid encoding one, or a chemotherapeutic agent.
