Background:

PF-622 is a potent, time-dependent, irreversible FAAH inhibitor [1].

Fatty acid amide hydrolase (FAAH), belongs to a member of an unusual class of serine hydrolases, is an integral membrane enzyme involved in regulating the fatty acid amide family of lipid transmitters. Genetic or pharmacological inactivation of FAAH leads to elevated endogenous levels of fatty acid amides with analgesic, anti-inflammatory, anxiolytic, and antidepressant phenotypes. The FAAH is an attractive drug target for the treatment of pain [1].

In vitro: PF-622 inhibited the activity of FAAH in a time-dependent manner with the IC50 values of 0.99 and 0.033 μM in human recombinant FAAH for 5 and 60 minutes, respectively [1]. In various human and murine tissue proteome samples, PF-622 showed highly selectivity for FAAH in relative to other serine hydrolases, showing no discernable off-site activity up to 500 μM [1]. PF-622 at 1 μM decreased IL-2 production in both healthy subjects and in HCV patients [2].
