[18F]Fluoride labelling of macromolecules in aqueous conditions: silicon and boroaryl-based [18F]fluorine acceptors, [18F]FDG conjugation and Al18F chelation
Journal of Labelled Compounds and Radiopharmaceuticals, 07/16/2012
Smith TAD – [18F]Fluorination is usually carried out by nucleophilic substitution reactions entailing the use of stringent conditions. A number of novel techniques including silicon and boron–based fluoride acceptor molecules, [18F]fluoro–2–deoxy– d–glucose and chelation of the Al18F complex have been employed recently to achieve [18F]radiolabelling of macromolecules. These approaches are reviewed herein.
