1-Azetidinecarbonitrile, 3-([1,1'-biphenyl]-4-ylmethoxy)-

NAAA-IN-3 (Compound 17a) is a potent and selective inhibitor of NAAA with an IC50 of 50 nM. NAAA is a cysteine amidase which preferentially hydrolyzes the endogenous biolipids palmitoylethanolamide (PEA) and oleoylethanolamide (OEA). NAAA-IN-3 has the potential for the research of inflammation and pain[1].
