2-((4-(1-[11C]Methyl-4-(pyridin-4-yl)-1H-pyrazol-3-yl)phenoxy) methyl)-quinoline (MP-10), a specific PDE10A inhibitor (IC50 = 0.18 nM with 100-fold selectivity over other PDEs), was radiosynthesized by alkylation of the desmethyl precursor with [11C]CH3I, ~45% yield, >92% radiochemical purity, >370 GBq/μmol specific activity at end of bombardment (EOB). Evaluation in Sprague-Dawley rats revealed that [11C]MP-10 had highest brain accumulation in the PDE10A enriched-striatum, the 30 min striatum: cerebellum ratio reached 6.55. MicroPET studies of [11C]MP-10 in monkeys displayed selective uptake in striatum. However, a radiolabeled metabolite capable of penetrating the blood-brain-barrier may limit the clinical utility of [11C]MP-10 as a PDE10A PET tracer.
