Bioactivity Comments
Inhibits FAAH by covalent, irreversible carbamylation of the active-site serine nucleophile of FAAH [2]. PF-04457845 shows some off-target inhibition of FAAH2, but does not inhibit other proteins of the endocannabinoid system, or endocannabinoid-binding transient receptor potential (TRP) ion channels [5].
