JZP-MA-11 is a positron emission tomography (PET) ligand that specifically targets the endocannabinoid α/β-hydrolase domain 6 (ABHD6) enzyme. It exhibits selective inhibition of ABHD6, achieving an IC50 value of 126 nM and is capable of crossing the blood-brain barrier (BBB). The compound, labeled with [18F], demonstrates promising potential for preclinical evaluation in both mice and nonhuman primates (NHP) as a tool for investigating brain ABHD6 activity [1].
