Molecular Weight 456.46 CAS No. 1196109-52-0
Solubility (25°C)* In vitro DMSO 91 mg/mL (199.36 mM)
Ethanol 91 mg/mL (199.36 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
30%propylene glycol 5%Tween80 65%D5W
15.0mg/ml Taking the 1 mL working solution as an example, add 300 μL of 50 mg/ml clarified propylene glycol stock solution to 50 μL of Tween 80, mix evenly to clarify it; then continue to add 650 μL of D5W to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description PF-3845 is a potent, selective and irreversible FAAH inhibitor with Ki of 230 nM, showing negligible activity against FAAH2.
Targets
FAAH [1]
230 nM(Ki)
In vitro

PF-3845 selectively inhibits FAAH by carbamylating FAAH's serine nucleophile. [1]
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. PF-3845 shows a long duration of action up to 24 hour. PF-3845-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. PF-3845 (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 PF-3845). At higher doses (10 and 30 mg/kg), PF-3845 inhibits pain responses to an equivalent, if not greater, degree than the nonsteroidal anti-inflammatory drug naproxen (10mg/kg, p.o.). [1] PF-3845 (10 mg/kg, i.p.) significantly reverses LPS-induced tactile allodynia, but doesn't modify paw withdrawal thresholds in the saline-injected paw. [2]
