Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	FAAH 230 nM(Ki)
In vitro	PF-3845 selectively inhibits FAAH by carbamylating FAAH's serine nucleophile.
In vivo	PF-3845 treated mice (10 mg/kg, i.p.) shows rapid and complete inactivation of FAAH in the brain, as judged by competitive activity-based protein profiling (ABPP) with the serine hydrolase-directed probe fluorophosphonate (FP)-rhodamine. This compound shows a long duration of action up to 24 hour. This compound-treated mice also shows dramatic (>10-fold) elevation in brain levels of AEA and other NAEs ( [PEA] and [OEA]). FAAH is AEA-degrading enzyme fatty acid amide hydrolase. This chemical (1–30 mg/kg, oral administration [p.o.]) causes a dose dependent inhibition of mechanical allodynia with a minimum effective dose (MED) of 3 mg/kg (rats are analyzed at 4 hour post dosing with this chemical). At higher doses (10 and 30 mg/kg), this compound inhibits pain responses to an equivalent, if not greater, degree than the nonsteroidal anti-inflammatory drug naproxen (10mg/kg, p.o.). This chemical (10 mg/kg, i.p.) significantly reverses LPS-induced tactile allodynia, but doesn't modify paw withdrawal thresholds in the saline-injected paw.
