Common Name10,11-Dihydro-12-oxo-LTB4
Description10,11-Dihydro-12-oxo-LTB4, also known as 12-oxo-10,11-dihydro-LTB(,4), 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-12-oxo-LTB4 is considered to be an eicosanoid lipid molecule. The PGs and TXs are collectively identified as prostanoids. 10,11-Dihydro-12-oxo-LTB4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Leukotrienes are eicosanoids. All mammalian cells except erythrocytes synthesize eicosanoids. Leukotrienes are metabolites of arachidonic acid derived from the action of 5-LO (5-lipoxygenase). 10,11-Dihydro-12-oxo-LTB4 was first documented in 1996 (PMID: 8632343). The immediate product of 5-LO is LTA4 (leukotriene A4), which is enzymatically converted into either LTB4 (leukotriene B4) by LTA4 hydrolase or LTC4 (leukotriene C4) by LTC4 synthase.
