    摘要： New and improved compounds for use in diagnostic imaging or therapy having the formula M-N—O—P-G, wherein M is a metal chelator having the structure: wherein R1-R5 and FG are as defined herein (in the form complexed with a metal radionuclide or not), N—O—P is the linker containing at least one non-alpha amino acid with a cyclic group, at least one substituted bile acid or at least one non-alpha amino acid, and G is the GRP receptor targeting peptide. In the preferred embodiment, M is an Aazta metal chelator or a derivative thereof. Methods for imaging a patient and/or providing radiotherapy or phototherapy to a patient using the compounds of the invention are also provided. Methods and kits for preparing a diagnostic imaging agent from the compound is further provided. Methods and kits for preparing a radiotherapeutic agent are further provided. Novel methods of treating prostate tumors or of delaying the progression of prostate tumors are also provided, including, methods of treating bone or soft tissue metastases of prostate cancer, methods for treating hormone sensitive and hormone refractory prostate cancer, methods for delaying the progression of hormone sensitive prostate cancer, for facilitating combination therapy in patients with hormone sensitive prostate cancer and for decreasing aberrant vascular permeability in patients with hormone sensitive prostate cancer.
