19(20)-EpDPE
IUPAC 名称
(4Z,7Z,10Z,13Z,16Z)-18-(3-ethyloxiran-2-yl)octadeca-4,7,10,13,16-pentaenoic acid
描述
19(20)-EpDPE is a DHA epoxygenase metabolite, derived via epoxidation of the w-3 double bond of DHA. The EDHF activity of 19(20)-EpDPE has not yet been determined. The epoxygenase metabolites of DHA have also been detected in a murine inflammation model
EDHF (endothelium-derived hyperpolarizing factor) is an unidentified mediator released from vascular endothelial cells in response to acetylcholine and bradykinin which is distinct from the NOS- (nitric oxide) and COX-derived (prostacyclin) vasodilators.1,2 Cytochrome P450 (CYP450) metabolism of polyunsaturated fatty acids produces epoxides such as 14(15)-EpETrE which are prime candidates for the actual active mediator.3 However, the CYP450 metabolites of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been little studied relative to arachidonate epoxygenase metabolites. 1 [HMDB]
