Solubility	METHANOL Morris_HR et al.
Source	Leukotriene D4 is produced by basophils, eosinophils and macrophages of various animal species upon various stimulations on the cells Samuelsson_B et al. Hammarstrom_S .
Chemical Synthesis	Cohen_N et al.
Metabolism	gamma -Glutamyl transpeptidase hydrolyzes the glutathione moiety of leukotriene C4 and produces leukotriene D4 liberating glutamic acid Hammarstrom_S ,
Biological Activity	Leukotriene D4 stimulates airway smooth muscles and causes bronchoconstriction. Vascular permeability is enhanced. Gasstrointestinal smooth muscles are contracted Samuelsson_B et al. Hammarstrom_S . Leukotriene D4 binds to a receptor with 7 transmembrane domains coupled to Gi alpha /o protein (CysLT1) with an affinity higher by two orders of magnitude than that of leukotriene C4 Lynch_KR et al..
Genetic Information	cDNA for CysLT1 was cloned Lynch_KR et al..
