Metabolite Identification
Common Name Trioxilin A3
Description Trioxilin A3 is the enzymatically formed derivative of Hepoxilin A3. Normal human epidermis incubated with exogenous AA produces 12-oxo-eicosatetraenoic acid (12-oxo-ETE), hepoxilin A3 (HxA3), and hepoxilin B3 (HxB3) through the 12- Lipoxygenase (LO) pathway. 12-LO is the major arachidonic acid (AA) oxygenation pathway in epidermal cells with total product formation generally exceeding cyclooxygenase activity. Platelet-type 12-LO has been found to be the predominant isoenzyme expressed in human and murine skin epidermis. Increased levels of nonesterified hepoxilins and trioxilins occur in the psoriatic scales. Normal human epidermis synthesized only one of the two possible 10-hydroxy epimers of HxB3 whose formation is probably catalyzed by 12-LO. Hepoxilins exert action on plasma permeability on skin, and induce a specific-receptor-dependent Ca2+ mobilization from endogenous sources and the release of AA and diacylglycerols.
