A novel class of lipids, N-acyltaurines, was recently discovered in fatty acid amide hydrolase knockout mice. In some peripheral tissues, such as liver and kidney, N-acyltaurines with long, polyunsaturated acyl chains are most prevalent. Polyunsaturated fatty acids are converted to a variety of signaling molecules by cyclooxygenases (COXs) and lipoxygenases (LOXs). The ability of COXs and LOXs to oxygenate arachidonoyltaurine was evaluated to gain insight into the potential metabolic fate of N-acyltaurines. Although arachidonoyltaurine was a poor substrate for COXs, mammalian 12 S- and 15 S-LOXs oxygenated arachidonoyltaurine with similar or better efficiency than arachidonic acid. Products of arachidonoyltaurine oxygenation were characterized by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The positional specificity of single oxygenation was retained for 15 S-LOXs. However, platelet-type 12 S-LOX produced 12- and 15-hydroxyeicosatetraenoyltaurines (HETE-Ts). Furthermore, LOXs generated dihydroxyeicosatetraenoyltaurines (diHETE-Ts). Metabolism of arachidonoyltaurine by murine resident peritoneal macrophages (RPMs) was also profiled. Arachidonoyltaurine was rapidly taken up and converted primarily to 12-HETE-T. Over prolonged incubations, RPMs also generated small amounts of diHETE-T. Oxidative metabolism of polyunsaturated N-acyltaurines may represent a pathway for the generation or termination of novel signaling molecules. << Less
