Chemical compound
Methoxy arachidonyl fluorophosphonate , commonly referred as MAFP , is an irreversible active site-directed enzyme inhibitor that inhibits nearly all serine hydrolases and serine proteases .[ 1] It inhibits phospholipase A2 and fatty acid amide hydrolase with special potency, displaying IC50 values in the low-nanomolar range. In addition, it binds to the CB1 receptor in rat brain membrane preparations (IC50 = 20 nM),[ 2] but does not appear to agonize or antagonize the receptor,[ 3] though some related derivatives do show cannabinoid-like properties.[ 4]
