Background:

(±)9(10)-DiHOME-d4is intended for use as an internal standard for the quantification of (±)9(10)-DiHOME by GC- or LC-MS. (±)9(10)-DiHOME is the diol form of (±)9(10)-EpOME , a cytochrome P450-derived epoxide of linoleic acid also known as leukotoxin.1It is formed from 9(10)-EpOME by soluble epoxide hydrolase (sEH) in neutrophils.29(10)-DiHOME has been used as a plasma biomarker for sEH activityin vivo.3It is toxic to Sf21 cells expressing sEH and tolacZ-expressing control cells, unlike leukotoxin, which is only toxic to cells containing sEH.1,2A mixture of 9(10)- and 12(13)-DiHOME induces cell death in rabbit renal proximal tubule cells concomitant with mitochondrial respiration dysfunction and induces lung injury, respiratory distress, and mortality in mice.4,59(10)-DiHOME is a toxic lipid mediator involved in acute respiratory distress syndrome (ARDs), a common and often fatal complication in severe burn victims.2,4Levels of 9(10)-DiHOME are increased in bronchoalveolar lavage fluid (BALF) from women, but not men, with chronic obstructive pulmonary disease (COPD).3BALF levels are also increased in patients with allergic asthma following provocation with birch pollen compared to patients without allergic asthma.6
