Leukotriene D4-d₅ 

Leukotriene D4-d₅ is the deuterium labeled Leukotriene D4. Leukotriene D4 is one of the constituents of slow-reacting substance of anaphylaxis (SRS-A) produced by the metabolism of LTC4 by γ-glutamyl transpeptidase. Leukotriene D4 is the first cysteinyl-leukotriene metabolite of LTC4. Leukotriene D4-induced bronchoconstriction and enhanced vascular permeability contribute to the pathogenesis of asthma and acute hypersensitivity.

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].
