Metabolite Identification
Common Name16(17)-EpDPE
Description16(17)-EpETE is the DHA homolog of 14(15)-EpETrE, derived via epoxidation of the 16,17-double bond of docosahexaenoic acid (DHA). The EDHF (endothelium-derived hyperpolarizing factor) activity of 16(17)-EpDPE has not yet been determined. The epoxygenase metabolites of DHA have also been detected in a murine inflammation model (PMID: 12391014 ). EDHF 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 (PMID: 9504399 , 10519554 ). Cytochrome P450 (CYP450) metabolism of polyunsaturated fatty acids produces epoxides such as 14(15)-EpETrE which are prime candidates for the actual active mediator (PMID: 9401962 ). However, the CYP450 metabolites of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been little studied relative to arachidonate epoxygenase metabolites.
