Resolvin D1-d5 (RvD1-d5) contains five deuterium atoms at the 21, 21', 22, 22, and 22 positions. It is intended for use as an internal standard for the quantification of RvD1 (Item No. 10012554) by GC- or LC-mass spectrometry. 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} RvD1 is produced physiologically from the sequential oxygenation of DHA by 15- and 5-lipoxygenase.{13989} A 17(R)-epimer of RvD1 can also be generated in aspirin-treated samples.{11433} 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.{15718} RvD1 and its aspirin-triggered form also exhibit a dose-dependent reduction in leukocyte infiltration in a mouse model of peritonitis with a maximal inhibition of ~35% at a 10-100 ng dose.{15718}
