Synthesis and Nicotinic Acetylcholine Receptor in Vivo Binding Properties of 2-Fluoro-3-[2(<i>S</i>)-2-azetidinylmethoxy]pyridine: A New Positron Emission Tomography Ligand for Nicotinic Receptors
GBq/micromol). In vivo characterization of [18F]F-A-85380 showed promising properties for PET imaging of central nAChRs. This compound does not bind in vivo to alpha7 nicotinic or 5HT3 receptors. Moreover, its cerebral uptake can be modulated by the synaptic concentration of the endogenous ligand acetylcholine. The preliminary PET experiments in baboons with [18F]F-A-85380 show an accumulation of the radiotracer
