The present invention concerns compounds and methods of labeling peptides or other molecules with
18
F or
19
F or any other suitable radionuclide of use, for example, in PET or NMR in vivo imaging. A targeting molecule such as a protein or a peptide is linked to a substituted metallocene complex which is reacted with the
1g
F or
19
F shortly before performing the PET or NMR in vivo imaging on the patient. The labeled molecule is then used for targeting a cell, tissue, organ or pathogen to be imaged or detected.
本发明涉及化合物和方法,用于标记肽或其他分子与18F或19F或任何其他适用的放射性核素,例如PET或NMR在体内成像。定位分子,例如蛋白质或肽,与取代的
金属环配合物连接,该
金属环配合物在对患者进行PET或NMR体内成像之前不久与1gF或19F反应。标记的分子然后用于定位要成像或检测的细胞、组织、器官或病原体。
