Stereochemical analysis of 12-hydroxy-5,8,10,14-eicosatetraenoic acid derived from the lesional scale of patients with psoriasis is reported. Resolution of the C-12 hydroxyl enantiomers was carried out by high pressure liquid chromatography of their diastereomeric methyl ester dehydroabietyl urethane derivatives.

Lipids and Lipid Metabolism, 1979
Production of several metabolites of arachidonic acid by purified rat serosal mast cells in response to stimulation with the ionophore A23187 was assessed by stable isotope dilution assay using gas chromatography-mass spectrometry. Compounds quantified were prostaglandins D2, E2, F2 alpha, 6-keto-F1 alpha, thromboxane B2, and 12-hydroxy-5,8,10,14 ...

Mouse peritoneal macrophages were incubated at 37 degrees C for 30 min with arachidonic acid (all-cis-5,8,11,14-eicosatetraenoic acid). Oxygenation of arachidonic acid in mouse peritoneal macrophages occurs by two major pathways: fatty acid cyclooxygenase and lipoxygenase. The major metabolite of the latter is 12-hydroxy-5,8,10,14-eicosatetraenoic acid

Studies were made on how age influenced the migration of aortic smooth muscle cells. For this, aortic cells from rats of various ages were established in culture in vitro and migration of the cells was measured by the filter membrane technique in modified Boyden chambers.

A method for the determination of 12-hydroxy-5,8,10,14-eicosatetraenoic acid (12-HETE) by gas chromatography-mass spectrometry (GC-MS) in samples obtained from healthy subjects by nasal lavage is presented. HETEs were extracted from samples obtained by nasal lavage using C18 solid-phase cartridges. The purification of 12-HETE and 5-HETE was carried out

The R and S enantiomers of 12-hydroxyeicosatetraenoic acid (12-HETE) exhibit different biological activities. Although they appear to be produced by different enzymatic pathways, cytochrome P-450 monooxygenase and lipoxygenase, respectively, they display similar metabolism in both corneal epithelium and neutrophils.

Abstract One of the pathways of metabolism of leukotriene B4 (LTB4) and 12-hydroxy-5,8,10,14-eicosatetraenoic acid (12-HETE) in leukocytes is oxidation of the 12-hydroxyl group, followed by reduction of the 10,11-double bond. In the case of 12R-HETE and 12S-HETE, this results in the formation of 12-oxo-ETE, 10,11-dihydro-12-oxo-ETE, and ...
