Radiofluorinated Enzyme Probes of Dopaminergic Function
Radiofluorinated analogs of enzyme substrates offer a useful strategy for designing radiotracers to probe or label specific enzymes and their function (1). They are being used to investigate the dopaminergic system in vivo to obtain information about the structural requirements associated with neurotransmitter enzyme function as well as critical information about pharmacological information and the effects of disease. Radiofluorinated enzyme probes (e.g. 6-[18F]fluoro-L-DOPA) have been useful to uncover the biochemical mechanisms behind specific brain tracer kinetic profiles and to understand kinetic changes occurring with the specifically designed radiotracers as a result of pharmacological interventions, centrally acting drugs (i.e., methamphetamine, cocaine), mood disorders or cell degeneration.
