| Common Name | 11,12,15-THETA |
|---|
| Description | 11,12,15-THETA 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. 11,12,15-THETA is an extremely weak basic (essentially neutral) compound (based on its pKa). 11,12,15-THETA is an endothelium-derived relaxing factor. 11,12,15-Theta can be biosynthesized from 15H-11,12-eeta through the action of the enzyme cytochrome P450 2C8. In humans, 11,12,15-theta is involved in mefenamic acid action pathway. 11,12,15-Trihydroxyeicosatrienoic acid (11,12,15-THETA) is a metabolite of the 15-lipoxygenase (15-LO) pathway of arachidonic acid (AA). The diacylglycerol (DAG) lipase can convert DAG into 2-arachidonoylglycerol from which free AA can be released by monoacylglycerol (MAG) lipase or fatty acid amidohydrolase (FAAH). AA is released from phosphatidylcholine (PC) and phosphatidylethanolamine (PE) by phospholipase A2 (PLA2), or from phosphatidylinositol (PI) by phospholipase C (PLC) pathway. 11,12,15-THETA mediates the acetylcholine-induced vaso-relaxation, via activation of the K+ channels to hyperpolarize the smooth muscle membrane and induce relaxation. Acetylcholine stimulates AA release from membrane phospholipids of vascular endothelial cells (ECs). |
