good selectivity over PDE4D, excellent brain permeability, and a high level of specific binding in the “cold tracer” study. In subsequent non-human primate (NHP) PET imaging studies, [18F]8 showed rapid brain uptake and high target specificity, indicating that [18F]8 is a promising PDE4B-preferring radioligand for clinical PET imaging.
