Description | 5,6-Epoxy-8,11,14-eicosatrienoic acid is an Epoxyeicosatrienoic acid (EET), a metabolite of arachidonic acid. The epoxyeicosatrienoic acids (EETs) are endogenous lipid mediators produced by P450 epoxygenases and metabolized through multiple pathways including soluble epoxide hydrolase (sEH). The cytochrome P-450 (P450) monooxygenase pathway includes enzymes of the CYP1A, CYP2B, CYP2C, CYP2E, and CYP2J subfamilies that catalyze the formation of four regioisomeric products, 5,6-, 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid. EETs are produced in brain and perform important biological functions, including protection from ischemic injury. Both light flashes and direct glial stimulation produce vasodilatation mediated by EETs. EETs may be involved in the development of hypertension and endothelial dysfunction in DOCA-salt rats, but not in excessive collagen deposition or electrophysiological abnormalities. EETs have vasodilator and natriuretic effect. Blockade of EET formation is associated with salt-sensitive hypertension. (PMID: 17494091 , 17468203 , 17434916 , 17406062 , 17361113 ). |
