Anchimeric chelating compounds which are capable of rapidly forming stable chelates with radionuclide metals at or below physiological temperatures are disclosed. The compounds possess a first site capable of complexing with a radionuclide metal which can be transferred to a second site (to form a chelate) by incubation, such as at 37°C or below. These anchimeric chelating compounds may be bifunctional and so are useful for radiolabelling target specific molecules such as monoclonal antibodies and fragments thereof, that may be specific for cancer cells.
本发明公开了能够在生理温度或生理温度以下与放射性核素
金属迅速形成稳定螯合物的嵌合螯合化合物。这些化合物具有一个能与放射性核素
金属络合的第一位点,通过培养,如在 37°C 或更低温度下培养,该位点可转移到第二位点(形成螯合物)。这些锚嵌螯合化合物可能具有双功能,因此可用于对癌细胞具有特异性的目标特异性分子(如单克隆
抗体及其片段)进行放射性标记。
