    • A new and improved method for extending the half life of pharmaceutical compounds for use in diagnostic imaging or therapy uses a novel linker to attach a diagnostic or therapeutic moiety to a targeting peptide or another diagnostic or therapeutic moiety. The resulting compound may have the general formula M-N—O—P-Q, wherein M is the diagnostic or therapeutic moiety, N—O—P is the linker of the present invention, and Q is the targeting peptide. In another embodiment the compounds may have the formula M-N—O—P-M, wherein M is independently a diagnostic or therapeutic moiety and N—O—P is the linker of the invention. Methods for imaging or treating a patient using the compounds of the invention are also provided. Methods and kits for preparing a diagnostic imaging agent from the compound are further provided. Methods for radiotherapy of a patient using the compounds are further provided, as are methods for preparing a radiotherapeutic agent from the compounds.
    • 用于延长用于诊断成像或治疗的药物化合物的半衰期的新的和改进的方法使用新的接头将诊断或治疗部分附着于靶向肽或另一诊断或治疗部分。 所得化合物可具有通式M-N-O-P-Q,其中M为诊断或治疗部分,N-O-P为本发明的接头,Q为靶向肽。 在另一个实施方案中,化合物可以具有式M-N-O-P-M,其中M独立地是诊断或治疗性部分,N-O-P是本发明的接头。 还提供了使用本发明化合物对患者进行成像或治疗的方法。 还提供了用于从化合物制备诊断显像剂的方法和试剂盒。 还提供了使用该化合物的患者放射治疗的方法,以及从化合物制备放射治疗剂的方法。
