This invention provides novel polydentate selective high affinity ligands (SHALs) that can be used in a variety of applications in a manner analogous to the use of antibodies. SHALs typically comprise a multiplicity of ligands that each bind different region son the target molecule. The ligands are joined directly or through a linker thereby forming a polydentate moiety that typically binds the target molecule with high selectivity and avidity.

This invention provides novel antibodies that specifically bind to the cancer antigen MUC-1. The antibodies are useful targeting moieties for specifically directing imaging agents and various therapeutic moieties to a cancer.

Anti-MUC-1 single chain antibodies for tumor targeting

A method of treating tumors, such as prostate tumors, breast tumors, non-Hodgkin's lymphoma, and the like, includes the sequential steps of administering to the patient at least one dose of an antiangiogenic cyclo-arginine-glycine-aspartic acid-containing pentapeptide (cRGD pentapeptide); administering to the patient an anti-tumor effective amount of a radioimmunotherapeutic agent (RIT); and then administering to the patient at least one additional dose of cRGD pentapeptide. The cRGD pentapeptide is preferably cyclo-(Arg-Gly-Asp-D-Phe-[N-Me]-Val), and the RIT is preferably a radionuclide-labeled chelating agent-ligand complex in which chelating agent is chemically bonded to a tumor-targeting molecule, such as a monoclonal antibody.

Method of treating tumors

Radionuclide-labeled chelating agent-ligand complexes that are useful in medical diagnosis or therapy are prepared by reacting a radionuclide, such as .sup.90 Y or .sup.111 In, with a polyfunctional chelating agent to form a radionuclide chelate that is electrically neutral; purifying the chelate by anion exchange chromatography; and reacting the purified chelate with a targeting molecule, such as a monoclonal antibody, to form the complex.

Method for preparing radionuclide-labeled chelating agent-ligand

A copper chelate conjugate which is stable in human serum. The conjugate includes the copper chelate of a cyclic tetraaza di-, tri-, or tetra-acetic acid, a linker attached at one linker end to a ring carbon of the chelate, and a biomolecule joined at the other end of the linker. The conjugate, or the linker-copper chelate compound used in forming the conjugate, are designed for use in diagnostic and therapeutic applications which involve Cu(II) localization via the systemic route.
