12-HETE

(5Z,8Z,10E,14Z)-(12S)-12-Hydroxyeicosa-5,8,10,14-tetraenoic acid

C20H32O3 (320.2351322)


12-Hydroxyeicosatetraenoic acid (CAS: 71030-37-0), also known as 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 the pathogenesis of hypertension and may mediate angiotensin II and TGFbeta induced mesangial cell abnormality in diabetic nephropathy. 12-HETE is markedly elevated in the psoriatic lesions. 12-HETE is a vasoconstrictor eicosanoid that contributes 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 hyperlipoproteinemia) 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 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 to be associated with peroxisomal biogenesis defect and Zellweger syndrome, which are inborn errors of metabolism.

   

Methylpyrazine

C5H6N2 (94.05309559999999)


Methylpyrazine is a member of the class of pyrazines that is pyrazine in which one of the hydrogens is replaced by a methyl group. It is a flavouring agent found in coffee, peanuts and red peppers. It has a role as a flavouring agent, a plant metabolite and a Maillard reaction product. 2-Methylpyrazine is a natural product found in Coffea, Coffea arabica, and other organisms with data available. Methylpyrazine is found in alcoholic beverages. Methylpyrazine is a flavouring agent. Methylpyrazine is present in many foods, e.g. bakery products, dairy products, meats, baked or French fried potato, roasted barley, cocoa, coffee, tea, roasted filbert, roasted pecan, peanut, soy products, rum and whisky.
