Isolation of a novel arachidonic acid metabolite 3-hydroxy-5,8,11,14-eicosatetraenoic acid (3-HETE) from the yeast Dipodascopsis uninucleata UOFs-Y128.
When arachidonic acid (AA) is added to the yeast Dipodascopsis uninucleata UOFS Y128, one of the major metabolites isolated and purified with the help of thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) is 3-hydroxy-5,8,11,14-eicosatetraenoic acid (3-HETE). The structure of this new AA metabolite was elucidated mainly by electron impact (EI) mass spectrometry (MS). Strikingly, the formation of this new metabolite was found to be inhibited by aspirin.
