The present disclosure provides a method for preparing a radioactive ligand or radioactive substrate having affinity for a target biomacromolecule, the method comprising: (a) reacting a first compound comprising a first functional group capable of participating in a click chemistry reaction, with a radioactive reagent under conditions sufficient to displace the leaving group with a radioactive component of the radioactive reagent to form a first radioactive compound; (b) providing a second compound comprising a second complementary functional group capable of participating in a click chemistry reaction with the first functional group; (c) reacting the first functional group of the first radioactive compound with the complementary functional group of the second compound via a click chemistry reaction to form the radioactive ligand or substrate; and (d) isolating the radioactive ligand or substrate.
本公开提供了一种制备具有亲和力的放射性
配体或放射性底物的方法,该方法包括:(a)将含有第一官能团的第一化合物与放射性试剂在足够条件下反应,以置换离去基团并与放射性试剂的放射性成分形成第一放射性化合物;(b)提供含有第二互补官能团的第二化合物,该官能团能够与第一官能团参与click
化学反应;(c)通过click
化学反应使第一放射性化合物的第一官能团与第二化合物的互补官能团反应,形成放射性
配体或底物;(d)分离放射性
配体或底物。
