Natural Product Identification
Common Name20-COOH-leukotriene E4
Description20-COOH-leukotriene E4, also known as 20-COOH-lte4, belongs to the class of organic compounds known as cysteine and derivatives. Cysteine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Thus, 20-COOH-leukotriene E4 is considered to be an eicosanoid lipid molecule. The PGs and TXs are collectively identified as prostanoids. 20-COOH-leukotriene E4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Leukotriene E4 (LTE4) is a cysteinyl leukotriene. 20-COOH-leukotriene E4 is a metabolite through lipid oxidation of Leukotriene E4 (LTE4). Leukotrienes are eicosanoids. Cysteinyl leukotrienes (CysLTs) are a family of potent inflammatory mediators that appear to contribute to the pathophysiologic features of allergic rhinitis.
