Formation of epoxyeicosatrienoic acids from arachidonic acid by cultured rat aortic smooth muscle cell microsomes. Prostaglandins, leukotrienes, and essential fatty acids, 1991, Volume: 42, Issue:3 The vasodilatory effect of epoxyeicosatrienoic acids (EpETrE), especially 5(6)-EpETrE, has been reported recently and a role of P-450-dependent arachidonic acid monooxygenase metabolites was suggested in vasoregulation. Accordingly, the presence of P-450-dependent arachidonic acid monooxygenase was investigated in rat aortic smooth muscle cells. Incubation of the microsomes of rat cultured aortic smooth muscle cells with 14C-arachidonic acid in the presence of 1 mM NADPH resulted in the formation of oxygenated metabolites. The metabolites were separated and purified by reverse phase and straight phase high performance liquid chromatography and identified by gas chromatography-mass spectrometry. Identified metabolites were 5(6)-EpETrE, 5,6-dihydroxyeicosatrienoic acid (DiHETrE), and 14,15-DiHETrE. The formation of these metabolites was totally dependent on the presence of NADPH, and inhibitors of cytochrome P-450-dependent enzymes, SKF-525A and metyrapone, reduced the formation of these metabolites. This is the first report that cytochrome P-450-dependent arachidonic acid metabolites, especially 5(6)-EpETrE and 14(15)-EpETrE, can be produced in the microsomes of vascular smooth muscle cells of rats.
