(±)8(9)-DiHET is primarily used in research focused on understanding the role of epoxyeicosatrienoic acids (EETs) and their metabolites in biological systems. It serves as a key intermediate in studies related to the cytochrome P450 pathway, particularly in the metabolism of arachidonic acid. Researchers utilize this compound to investigate its effects on vascular and inflammatory processes, as it is involved in the regulation of blood pressure and vascular tone. Additionally, it is employed in studies exploring its potential therapeutic applications in cardiovascular diseases and inflammatory disorders. Its role in modulating cellular signaling pathways makes it a valuable tool in biochemical and pharmacological research.
