12-HETE
IUPAC 名称
12-hydroxyicosa-5,8,10,14-tetraenoic acid
描述
12-hydroxyeicosatetraenoic acid (12-HETE) is an eicosanoid, a 5-lipoxygenase metabolite of arachidonic acid. 5-Lipoxygenase (LO)-derived leukotrienes are involved in inflammatory glomerular injury. LO product 12-HETE is associated with pathogenesis of hypertension, and may mediate angiotensin II and TGFbeta induced mesengial cell abnormality in diabetic nephropathy. 12-HETE is markedly elevated in the psoriatic lesions. 12-HETE is a vasoconstrictor eicosanoid that contribute to high blood pressure in (renovascular) hypertension and pregnancy-induced hypertension. A significant percentage of patients suffering from a selective increase in plasma LDL cholesterol (type IIa hyperlipoproteinaemia) exhibits increased platelet reactivity. This includes enhanced platelet responsiveness against a variety of platelet-stimulating agents ex vivo and enhanced arachidonic acid metabolism associated with increased generation of arachidonic acid metabolites such as 12-HETE, and secretion of platelet-storage products. (PMID: 7562532, 12480795, 17361113, 8498970,1333255, 2119633). 12-HETE is a highly selective ligand used to label mu-opioid receptors in both membranes and tissue sections. The 12-s-HETE analog has been reported to augment tumour cell metastatic potential through activation of protein kinase c. 12-HETE can be formed either in the 12-S or 12-R configuration. It has a diversity of biological actions and is generated by a number of tissues including the renal glomerulus and the vasculature. 12-HETE is one of the six monohydroxy fatty acids produced by the non-enzymatic oxidation of arachidonic acid. 12-HETE is a neuromodulator that is synthesized during ischemia. Its neuronal effects include attenuation of calcium influx and glutamate release as well as inhibition of AMPA receptor (AMPA-R) activation. 12-HETE is found in corn.
