| Common Name | 12-Oxo-20-dihydroxy-leukotriene B4 |
|---|
| Description | 12-Oxo-20-dihydroxy-leukotriene B4, also known as OX20DHLTB4, belongs to the class of organic compounds known as leukotrienes. These are eicosanoids containing a hydroxyl group attached to the aliphatic chain of an arachidonic acid. Leukotrienes have four double bonds, three (and only three) of which are conjugated. Thus, 12-oxo-20-dihydroxy-leukotriene B4 is considered to be an eicosanoid lipid molecule. 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. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. 12-Oxo-20-dihydroxy-leukotriene B4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. The PGs and TXs are collectively identified as prostanoids. LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Omega-oxidation is the major pathway for the catabolism of leukotriene B4 in human polymorphonuclear leukocytes. |
