Oleoyl proline is an N-acyl amine that can be detected in bovine brain extracts and D. melanogaster larvae using mass spectrometry. In a preclinical model of pain, mice lacking fattyacidamidehydrolase (FAAH KO) had decreased N-oleoyl proline levels in
MDPD is an enhancer of the N-acylethanolamine degrading enzyme, fattyacidamidehydrolase, in Arabidopsis. MDPD alleviates the growth inhibitory effects of NAE 12:0, in part by enhancing the enzymatic activity of Arabidopsis FAAH (AtFAAH).
