McN3716 (Methyl palmoxirate)

Animal experiment:

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.
