ResolvinD2 (RvD2) is a lipid mediator biosynthesized by the sequential oxygenation of docosahexaenoic acid by 15- and 5-lipoxygenase. It evokes diverse anti-inflammatory effects which may mediate the resolution of inflammation. RvD2methylester is a methylester version of the free acid which may act as a lipophilic prodrug form that will alter its distribution and pharmacokinetic properties. The methylester moiety is susceptible to cleavage by intracellular esterases, leaving the free acid.
