  • Patent number: 6183722
    Abstract: This invention relates to therapeutic reagents and peptides, including radiotherapeutic reagents and peptides, radiodiagnostic reagents and peptides, and methods for producing labeled radiodiagnostic agents. Specifically, the invention relates to cyclic peptide derivatives and analogs of somatostatin, and embodiments of such peptides radiolabeled with a radioisotope, as well as methods and kits for making, radiolabeling and using such peptides for radiodiagnostic and radiotherapeutic purposes. The invention specifically relates to cyclic peptide derivatives and analogues of somatostatin radiolabeled with technetium-99m and uses thereof as scintigraphic imaging agents. The invention also specifically relates to cyclic peptide derivatives and analogues of somatostatin radiolabeled with cytotoxic radioisotopes such as rhenium-186 (186Re) and rhenium-188 (188Re) for use as radiotherapeutic agents.

  • Patent number: 6150329
    Abstract: This invention relates to antithrombotic agents and uses thereof. Specifically, the invention relates to chemical moieties that specifically bind to platelets and inhibit their aggregation, including linear and cyclic peptides. The invention provides methods for using these antithrombotic agents to prevent the formation of thrombi at sites in a mammalian body. In particular, the platelet-specific binding moieties including linear and cyclic peptides of the invention are covalently linked to a polyvalent linker moiety, so that the polyvalent linker moiety is covalently linked to a multiplicity of the platelet-specific binding moieties including linear and cyclic peptides. Effficacious antithrombotic agents are thereby provided.
