17(R)-Resolvin D1

Resolvins are a family of potent lipid mediators derived from both eicosapentaenoic acid (EPA, Cay-90110) and docosahexaenoic acid (DHA, Cay-90310). In addition to being anti-inflammatory, resolvins promote the resolution of the inflammatory response back to a non-inflamed state. Resolvin D1 (RvD1, Cay-10012554) is produced physiologically from the sequential oxygenation of DHA by 15- and 5-lipoxygenase. 17(R)-RvD1 is an aspirin-triggered epimer of RvD1 that reduces human polymorphonuclear leukocyte (PMN) transendothelial migration, the earliest event in acute inflammation, with equipotency to RvD1 (EC50 = ~30 nM). 17(R)-RvD1 exhibits a dose-dependent reduction in leukocyte infiltration in a mouse model of peritonitis with maximal inhibition of ~35% at a 100 ng dose. In contrast to RvD1, the aspirin-triggered form resists rapid inactivation by eicosanoid oxidoreductases.Formal Name: 7S,8R,17R-trihydroxy-4Z,9E,11E,13Z,15E,19Z-docosahexaenoic acid.
