| 摘要 |
This invention relates to radiotherapeutic reagents and peptides, radiodiagnostic reagents and peptides, and methods for producing labeled radiodiagnostic and radiotherapeutic agents. Specifically, the invention relates to vasoactive intestinal receptor binding peptides, derivatives and analogues of vasoactive intestinal peptide, 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 vasoactive intestinal receptor binding peptide derivatives and analogues of vasoactive intestinal peptide radiolabeled with technetium-99m and uses thereof as scintigraphic imaging agents. The invention also specifically relates to vasoactive intestinal receptor binding peptide derivatives and analogues of vasoactive intestinal peptide radiolabeled with cytotoxic radioisotopes such as rhenium-186 (186Re) and rhenium-188 (188Re) for use as radiotherapeutic agents. Methods and kits for making, radiolabeling and using such peptides diagnostically and therapeutically in a mammalian body are also provided.
