N-Oleoyl leucine is an N-acyl amide generated by PM20D1 that uncouples mitochondrial respiration independent of uncoupling protein 1 (UCP1) in vitro.¹ N-Oleoyl leucine (25 mg/kg, i.p.) decreases body weight and food intake, preferentially decreasing fat mass in a diet-induced obesity mouse model. It improves glucose homeostasis in a fasting glucose tolerance test and increases VO₂ while slightly decreasing overall locomotor activity.

ChEBI: N-oleoyl-L-leucine is an L-leucine derivative resulting from the formal condensation of the carboxy group of oleic acid with the amino group of L-leucine. It is a L-leucine derivative and a N-(fatty acyl)-L-alpha-amino acid. It is functionally related to an oleic acid. It is a conjugate acid of a N-oleoyl-L-leucinate.
