Leukotriene D4 (LTD4) is one of the constituents of slow-reacting substance of anaphylaxis (SRS-A) produced by the metabolism of LTC4 by γ-glutamyl transpeptidase.1,2 LTD4-induced bronchoconstriction and enhanced vascular permeability contribute to the pathogenesis of asthma and acute hypersensitivity.3,4 LTD4 is several hundred fold more potent than LTC4 at the cysteinyl-leukotriene 1 (CysLT1) receptor, but they exhibit approximately equal affinity at the CysLT2 receptor.5,6 LTD4 methyl ester is a more lipid soluble form of LTD4. The biological activity of LTD4 methyl ester has not been reported.WARNING This product is not for human or veterinary use.
