Resolvin E1-d4 (RvE1-d4) is intended for use as an internal standard for the quantification of RvE1 (Item No. 10007848) by GC- or LC-MS. RvE1 is a member of the specialized pro-resolving mediator (SPM) family of bioactive lipids.{58455} It is produced from eicosapentaenoic acid (EPA; Item No. 90110 | 90110.1 | 21908) via an 18-HEPE epoxide intermediate, which is formed by aspirin-acetylated COX-2-mediated oxidation of EPA and 5-lipoxygenase (5-LO), by leukotriene A4 (LTA4) hydrolase in human polymorphonuclear (PMN) neutrophils. RvE1 activates chemokine-like receptor 1 (CMKLR1; EC50 = 0.137 nM in a reporter assay). RvE1 (20 ng/animal) inhibits increases in inflammatory exudate neutrophil infiltration in a mouse model of peritonitis induced by zymosan A (Item No. 21175). It increases survival and prevents decreases in colon length in a mouse model of TNBS-induced colitis when administered at a dose of 50 µg/kg.{13209} RvE1 (50 µg/kg) inhibits ovalbumin-induced increases in eosinophil and total cell numbers, as well as IL-13 and IgE levels in bronchoalveolar lavage fluid (BALF) in an ovalbumin-sensitized mouse model of asthma.{15876}
