874902-19-9

LY-2183240 (874902-19-9) is highly potent inhibitor of cellular anandamide uptake (IC50 = 0.27nM1, 15nM2). LY-2183240 has also been found2-4 to be an inhibitor of fatty acid amide hydrolase (FAAH) – IC50 = 14nM4, diacylglycerol lipase (DAGL) and monoacylglycerol lipase (MAGL) – IC50 = 5.3 nM3.

LY2183240 is a potent inhibitor of FAAH activity, and the uptake and enzymatic hydrolysis of anandamide. Synthetic Cannabinoids

ChEBI: N,N-dimethyl-5-[(4-phenylphenyl)methyl]-1-tetrazolecarboxamide is a member of biphenyls.

Novel and highly potent blocker of anandamide uptake (IC 50 = 270 pM). Inhibits fatty acid amide hydrolase (FAAH) activity (IC 50 = 12.4 nM). Following i.p. administration in rats, increases brain anandamide concentration and exerts antinociceptive effects in formalin model of pain.
