N-Oleoyl Glutamine

N-Oleoyl glutamine is an endogenous N-acyl amine.^1,2 It is both formed and degraded by peptidase M20 domain-containing 1 (PM20D1), a factor secreted by thermogenic adipose cells. N-Oleoyl glutamine (50 µM) induces mitochondrial uncoupling to increase respiration in C2C12 cells by 64%.³ It inhibits capsaicin-induced calcium flux in HEK293A cells co-transfected with transient receptor potential vanilloid 1 (TRPV1) and red fluorescent protein (RFP).² N-Oleoyl glutamine (100 mg/kg) reduces the number of acetic acid-induced abdominal constrictions, as well as formalin-induced paw licking in mice.
