Solubility	METHANOL Corey_EJ et al.
Source	Leukotriene C4 is produced by polymorphonuclear leukocytes, mast cells and macrophages of various animal species upon various stimulations on the cells Samuelsson_B et al. Hammarstrom_S .
Chemical Synthesis	Corey_EJ et al.
Metabolism	Arachidonic acid is metabolized to leukotrienen A4 with 5,6-epoxide by 5-lipoxygenases, and the product is further transformed to leukotrienee C4 incorporating glutathione by the catalysis of leukotriene C synthase Samuelsson_B et al..
Biological Activity	Leukotriene C4 is a potent stimulator of airway smooth muscles and causes bronchoconstriction as demonstrated in vitro and in vivo experiments, and gastrointestinal smooth muscles are also contracted. Vascular permeability is enhanced by leukotriene C4 at concentrations lower by 3-4 orders of magnitude than histamine Hammarstrom_S . Gasstrointestinal smooth muscles are contracted Samuelsson_B et al. Hammarstrom_S . Leukotriene C4 binds to a receptor with 7 transmembrane domains coupled to Gi α /o protein (CysLT1) with an affinity lower by two orders of magnitude than that of leukotriene D4 Lynch_KR et al..
Genetic Information	cDNA and genomic DNA of 5-lipoxygenase Funk_CD and those for leukotriene C synthase Lam_BK et al. Penrose_JF et al. were cloned. cDNA for CysLT1 was cloned Lynch_KR et al..
