Resolvins are a family of potent lipid mediators derived from both eicosapentaenoic acid (EPA) and docosahexaenoic (DHA).1 In addition to being anti-inflammatory, resolvins promote the resolution of the inflammatory response back to a non-inflamed state.2 Resolvin D1 (RvD1) is produced physiologically from the sequential oxygenation of DHA by 15- and 5-lipoxygenase.1 A 17(R)-epimer of RvD1 can also be generated in aspirin-treated samples.3 Both RvD1 and its 17(R) configuration reduce human polymorphonuclear leukocyte (PMNL) transendothelial migration, the earliest event in acute inflammation, with EC50 values of ~30 nM.4 RvD1 and its aspirin-triggered form also exhibit a dose-dependent reduction in leukocyte infiltration in a murine model of peritonitis with a maximal inhibition of ~35% at a 10-100 ng dose.4
