The present invention provides compounds and pharmaceutical compositions for inhibiting N-acylethanolamine acid amidase (NAAA). Inhibition of NAAA is contemplated as a method to sustain the levels of palmitoylethanolamide (PEA) and oleylethanolamide (OEA), two substrates of NAAA, in conditions characterized by reduced concentrations of PEA and OEA. The invention also provides methods for treating inflammatory diseases and pain, and other disorders in which decreased levels of PEA and OEA are associated with the disorder.

Synthesis and Structure–Activity Relationship (SAR) of 2-Methyl-4-oxo-3-oxetanylcarbamic Acid Esters, a Class of Potent <i>N</i>-Acylethanolamine Acid Amidase (NAAA) Inhibitors
(2) and (S)-N-(2-oxo-3-oxetanyl)-biphenyl-4-carboxamide (3) inhibitNAAA, prevent FAE hydrolysis in activated inflammatory cells, and reduce tissue reactions to pro-inflammatory stimuli. Recently, our group disclosed ARN077 (4), a potent NAAAinhibitor that is active in vivo by topical administration in rodent models of hyperalgesia and allodynia. In the present study, we investigated the structure–activity
