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.

The cysteine amidase N-acylethanolamine acid amidase (NAAA) is a member of the N-terminal nucleophile class of enzymes and a potential target for anti-inflammatory drugs. We investigated the mechanism of inhibition of human NAAA by substituted beta-lactones. We characterized pharmacologically a representative member of this class, ARN077, and showed, using high-resolution liquid chromatography-tandem mass spectrometry, that this compound forms a thioester bond with the N-terminal catalytic cysteine in human NAAA.

peroxisome proliferator‐activated receptor‐α (PPAR‐α). Compounds that feature an α‐amino‐β‐lactone ring have been identified as potent and selective NAAA inhibitors and have been shown to exert marked anti‐inflammatory effects that are mediated through FAE‐dependent activation of PPAR‐α. We synthesized and tested a series of racemic, diastereomerically pure β‐substituted α‐amino‐β‐lactones, as either carbamate
