Epoxyeicosatrienoic acid


Chemical structure of 14,15-epoxyeicosatrienoic acid.

The Epoxyeicosatrienoic acids or EETs are signaling molecules formed by the action of Cytochrome P450 epoxygenase on 20-carbon essential fatty acids, such as arachidonic acid. These nonclassic eicosanoids act as short-range hormones, (i.e. they are autocrine and paracrine mediators) of the cardiovascular system and kidney. They produce vasorelaxation as well as anti-inflammatory and pro-fibrinolytic effects.[1]

Biological effects

Biological effects

EETs are cardioprotective after ischemic heart attack and reperfusion.[2] They act in the corpus cavernosum to maintain penile erection.[3] Specific epoxidation of EET sites produces endogenous PPARα agonists.[4]
