The present invention relates to a ligand-SIFA-chelator conjugate, comprising, within in a single molecule three separate moieties:(a)one or more ligands which are capable of binding to a disease-relevant target molecule, (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, optionally containing a chelated nonradioactive or radioactive cation.
本发明涉及一种
配体-SIFA-螯合物共轭物,包括单个分子内的三个不同部分:(a)一种或多种能够结合疾病相关靶分子的
配体,(b)一个含有
硅氟受体(SIFA)的分子,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,可选地包含螯合的非放射性或放射性阳离子。
