Natural Product Identification
Common Name10,11-Dihydro-leukotriene B4
Description10,11-Dihydro-leukotriene B4, also known as 10,11-dihydro-LTB(,4) or DHLTB4, belongs to the class of organic compounds known as hydroxyeicosatrienoic acids. These are eicosanoic acids with an attached hydroxyl group and three CC double bonds. Thus, 10,11-dihydro-leukotriene B4 is considered to be an eicosanoid lipid molecule. The PGs and TXs are collectively identified as prostanoids. 10,11-Dihydro-leukotriene B4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Leukotrienes are eicosanoids. The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region, and phosphorylation to either enhance or inhibit the activity of 5-LO. It was first documented in 1984 (PMID: 6088485). All mammalian cells except erythrocytes synthesize eicosanoids (PMID: 11413487) (PMID: 17623009) (PMID: 7649996) (PMID: 2853166).
