Carnitine palmitoyltransferase I (CPT-1)[1]

In Vivo Inhibition of brain mitochondrial β-oxidation by McN3716 (Methyl palmoxirate, MEP) significantly reduces the levels of all measured HETE and epoxytrienoic acids (EET), nonenzymatic auto-oxidative metabolites of ARA, by 23% to 44% and 32% to 50% compared with vehicle-injected rats, respectively, except for 15-HETE which was unaffected. There is a significant 34% reduction in the level of 6-keto-PGF1α, a byproduct of PGI2 (prostacyclin) in McN3716-treated rats. Similarly, the brain level of hydroxyeicosapentaenoic acids, nonenzymatic auto-oxidative metabolites of EPA, is reduced by 35% to 76% upon McN3716 treatment relative to vehicle[1].
Animal Admin Rats[1] Male Sprague Dawley rats are used. The rats receive ad libitum access to standard chow and water. At 15 weeks of age, six rats were subjected to either high-energy, head-focused microwave irradiation or CO2 asphyxiation. A separate group of 11 rats were implanted with a tail vein catheter (intravenous catheter 24 gauge/0.75 inch) and received either an intravenous injection of vehicle or 10 mg/kg of McN3716. Fifteen minutes after injection, rats were rapidly euthanized by high-energy, head-focused microwave irradiation (13.5 kW for 1.6 seconds) to avert ischemia for accurate quantification of in vivo basal levels of nonenzymatic auto-oxidative PUFA metabolites and enzymatically derived metabolites. Previously, we reported that this method reduced β-oxidation of fatty acid by 23% to 74%. McN3716 (Methyl palmoxirate, MEP) readily crosses the blood–brain barrier with a plasma half-life of 0.6 minute in the rat. The brain was excised and stored at -80°C for lipidomics profiling.
