The invention relates to radiodiagnostic and radiotherapeutic agents, including biologically active vectors labelled with radionuclides. It further relates to methods and reagents labelling a vector such as a peptide comprising reaction of a compound of formula (I) with a compound of formula (II):
R*-L2-N3 (II)
or,
a compound of formula (III) with a compound of formula (IV)
in the presence of a Cu (I) catalyst. The resultant labelled conjugates are useful as diagnostic agents, for example, as radiopharmaceuticals more specifically for use in Positron Emission Tomography (PET) or Single Photon Emission Computed Tomography (SPECT) or for radiotherapy.
本发明涉及放射性诊断和放射治疗药物,包括用放射性核素标记的
生物活性载体。本发明还涉及标记肽等载体的方法和试剂,包括式(I)化合物与式(II)化合物的反应:
R*-
L2-N3 (II)
或
式(III)化合物与式(IV)化合物
在 Cu (I)
催化剂存在下。由此产生的标记共轭物可用作诊断剂,例如,可用作放射性药物,特别是用于正电子发射断层扫描(PET)或单光子发射计算机断层扫描(
SPECT)或放射治疗。
