General description

A cell-permeable carbamate compound that acts as a potent, selective, and irreversible inhibitor of fatty acid amide hydrolase (FAAH; IC50 = 4.6 nM in brain membranes). Shown to block anandamide (Cat. No. 172100) breakdown in rat cortical neurons (IC50 = 500 pM) and modulate anxiety in rats (ID50 = 0.15 mg/Kg). Does not affect the activities of several serine hydrolases (IC50 >30 µM), including AChE (acetylcholinesterase), BCh (butyrylcholinesterase) and MGL (monoglyceride lipase). It also does not interfere with the binding of anandamide to cannabinoid receptors CB1 and CB2 (IC50 >100 µM), as well as several ion-channels and neurotransmitter transporters.
A cell-permeable, carbamate compound that acts as a potent, selective, and irreversible inhibitor of fatty acid amide hydrolase (FAAH; IC50 = 4.6 nM in brain membranes). Shown to block anandamide (Cat. No. 172100) breakdown in rat cortical neurons (IC50 = 0.5 nM) and modulate anxiety in rats (ID50 = 0.15 mg/Kg). Does not affect the activities of several serine hydrolases, namely, AchE (acetyl cholinesterase) (IC50 >100 µM), BCh (butyryl cholinesterase) (IC50 >100 µM), and MGL (monoglyceride lipase) (IC50 >30 µM). Does not interfere with the binding of anandamide to cannabinoid receptors, CB1 and CB2 (IC50 >100 µM), several ion-channels, or neurotransmitter transporters.
