Leukotriene E4-d₅  (Synonyms: LTE4-d₅)

Leukotriene E4-d₅ is the deuterium labeled Leukotriene E4. Leukotriene E4 (LTE4) is produced by the action of dipeptidase on LTD4. Leukotriene E4 is one of the constituents of slow-reacting substance of anaphylaxis (SRS-A). Leukotriene E4 accumulates in both plasma and urine and urinary excretion of Leukotriene E4 is most often used as an indicator of asthma.

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
