Preclinical evaluation of [18F]JNJ42259152 as a PET tracer for PDE10A

In conclusion we can state that in vivo imaging in PDE10A KO mice, rats and monkey demonstrates that [18F]JNJ42259152 provides a PDE10A-specific signal in the striatum with good pharmacokinetic properties. Although presence of a polar radiometabolite in rat brain yielded a systematic but reproducible underestimation of the striatal BPND, a Logan reference tissue model approach using 60 min acquisition data is appropriate for quantification.
