17(R)-Resolvin D1

Resolvins are a family of potent lipid mediators derived from both eicosapentaenoic acid (EPA; Item No. 90110) and docosahexaenoic acid (DHA; Item No. 90310).{13989} In addition to being anti-inflammatory, resolvins promote the resolution of the inflammatory response back to a non-inflamed state.{14973} Resolvin D1 (RvD1; Item No. 10012554) is produced physiologically from the sequential oxygenation of DHA by 15- and 5-lipoxygenase.{13989} 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).{15718} 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.{15718} In contrast to RvD1, the aspirin-triggered form resists rapid inactivation by eicosanoid oxidoreductases.
