The present invention relates to a ligand-SIFA-chelator conjugate, comprising, within a single molecule three separate moieties: (a) one or more ligands which are capable of binding to PSMA, (b) a silicon-fluoride acceptor (SIFA) moiety which comprises a covalent bond between a silicon atom and a fluorine atom, and (c) one or more chelating groups, containing a chelated nonradioactive cation.
本发明涉及一种
配体-SIFA-螯合物共轭物,包括在一个分子内的三个单独的部分:(a) 一个或多个能够结合到PSMA的
配体,(b) 一个
硅氟受体(SIFA)部分,其中包括
硅原子和
氟原子之间的共价键,以及(c) 一个或多个螯合基团,含有螯合的非放射性阳离子。
