19R(20S)-EpDPA is an oxylipin and a metabolite of docosahexaenoic acid .1,2 It is formed from DHA by various cytochrome P450 (CYP) isoforms in a stereoselective manner.2 19R(20S)-EpDPA (30 nM) prevents calcium-induced increases in the spontaneous beating of isolated neonatal rat cardiomyocytes (NRCMs).3
