report the rapid identification of a novel phosphodiesterase10A (PDE10A) tracer candidate using a LC–MS/MS technology. This structurally distinct PDE10A tracer, AMG-7980 (5), has been shown to have good uptake in the striatum (1.2% ID/g tissue), high specificity (striatum/thalamus ratio of 10), and saturable binding in vivo. The PDE10A affinity (KD) and PDE10A target density (Bmax) were determined to
