20100104511METHODS AND COMPOSITIONS USING CHELATOR-ANTIBODY CONJUGATES - Disclosed are pharmaceutical compositions that include a chelator and an antibody directed against a phosphorylation site of a protein, wherein the antibody is conjugated to the chelator to form a chelator-antibody conjugate. For example, the antibody may recognize a phosphorylated tyrosine residue or a phosphorylated serine residue of a cell surface receptor. Also disclosed are methods of synthesizing a radiolabeled chelator-antibody conjugate, wherein the antibody is directed against a phosphorylation site of a protein. Also disclosed are methods for imaging a site in a subject that involve administering to the subject an effective amount of a composition that includes a valent metal ion-labeled chelator-antibody conjugate, wherein the antibody is an antibody directed against a phosphorylation site of a protein, and detecting a radioactive signal from the site in the subject following administration of an effective amount of the composition. The method of imaging can be applied in diagnosing a tumor, such as a tumor that can be responsive to therapy using a tyrosine kinase inhibitor, and in the treatment of a tumor, such as by targeting therapy to cell surface receptors that include phosphorylation sites.04-29-2010

The glycopeptides may also include a diagnostic or therapeutic agent bound to the glycopeptide. A metal, such as a radionuclide, may also be chelated to the glycopeptide. Specific embodiments of the invention relate to glycopeptides made of chitosan covalently bound to a poly(amino acid) such as poly(glutamic acid) or poly(aspartic acid). Diagnostic agents conjugated to the glycopeptide may facilitate imaging. Specific therapeutic agents that may be conjugated to the glycopeptide include anticancer drugs, rheumatoid arthritis drugs, anticoagulants, anti-angiogenesis drugs, apoptosis drugs, osteoporosis drugs, steroids, and anti-inflammatory drugs. Some agents, such as radionuclides, may have both diagnostic and therapeutic effects. The glycopeptides may be made by combining a glycoside and a peptide in the presence of a carbodiimide and an acid group activator to form an amide bond between the glycoside and the peptide.04-14-2011
