Leukotriene D4 methyl ester

Leukotriene D4 (LTD4) is one of the constituents of slow-reacting substance of anaphylaxis (SRS-A) produced by the metabolism of LTC4 by gamma-glutamyl transpeptidase. LTD4-induced bronchoconstriction and enhanced vascular permeability contribute to the pathogenesis of asthma and acute hypersensitivity. 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. LTD4 methyl ester is a more lipid soluble form of LTD4. The biological activity of LTD4 methyl ester has not been reported.Formal Name: 5S-hydroxy-6R-(S-cysteinylglycinyl)-7E,9E,11Z,14Z-eicosatetraenoic acid, methyl ester. Synonyms: LTD4 methyl ester.
