(±)12(13)-EpOME-d4 is intended for use as an internal standard for the quantification of (±)12(13)-EpOME by GC- or LC-MS. (±)12(13)-EpOME is the 12,13-cis epoxide form of linoleic acid .1,2 It is formed primarily via linoleic acid metabolism by the cytochrome P450 (CYP) isoforms CYP2J2, CYP2C8, and CYP2C9, however, CYP1A1 can contribute to (±)12(13)-EpOME production when pharmacologically induced.2 (±)12(13)-EpOME (500 µM) induces mitochondrial dysfunction and cell death in renal proximal tubule epithelial cells.
