radionuclides lack the necessary positronemission. This work reports on the synthesis of dual-nuclide labeled radiopharmaceuticals with therapeutic and PET functionality, which are based on common and widely available metal radionuclides. Dual-chelator conjugates, featuring interlinked cyclen- and triazacyclononane-based polyphosphinates DOTPI and TRAP, allow for strictly regioselective complexation
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.
