Metabolite Identification
Common Name11,12-DiHETrE
Description11,12-DiHETrE is a Cytochrome P450 (P450) eicosanoid. Arachidonic acid may be oxygenated by cytochrome P450 in several ways. Epoxidation of the double bonds leads to the regio- and enantioselective formation of four epoxyeicosatrienoic acids (EETs), which are hydrolyzed by epoxide hydrolase to vicinal diols (DHETs). 11,12-DiHETrE excretion is increased in healthy pregnant women compared with nonpregnant female volunteers, and increased even further in patients with pregnancy-induced hypertension (PIH). The physiological significance of arachidonic acid epoxides has been debated and it is unknown whether they play a role in pregnancy and parturition. Vasodilative effects, inhibition of cyclooxygenase, or inhibition of platelet aggregation by EETs have been observed only at micromolar concentrations. On the other hand, effects on the stimulus-secretion coupling during hormone release have been found in the nanomolar and picomolar range. (PMID: 9440131 , 2198572 ).

Enzymes

General function:
Involved in catalytic activity
Specific function:
Bifunctional enzyme. The C-terminal domain has epoxide hydrolase activity and acts on epoxides (alkene oxides, oxiranes) and arene oxides. Plays a role in xenobiotic metabolism by degrading potentially toxic epoxides. Also determines steady-state levels of physiological mediators. The N-terminal domain has lipid phosphatase activity, with the highest activity towards threo-9,10-phosphonooxy-hydroxy-octadecanoic acid, followed by erythro-9,10-phosphonooxy-hydroxy-octadecanoic acid, 12-phosphonooxy-octadec-9Z-enoic acid, 12-phosphonooxy-octadec-9E-enoic acid, and p-nitrophenyl phospate.
