12(S)-HpEPE (CAS 103239-14-1)

12(S)-HpEPE, registered under CAS number 103239-14-1, is a hydroperoxy eicosapentaenoic acid derivative specifically characterized by its S-enantiomer configuration. This compound is a product of the enzymatic oxidation of eicosapentaenoic acid (EPA), a polyunsaturated fatty acid, primarily mediated by lipoxygenase enzymes. As a member of the hydroperoxy fatty acids, 12(S)-HpEPE plays a pivotal role in the investigation of lipid oxidation processes and their implications in cellular signaling pathways. The significance of 12(S)-HpEPE in research lies in its function as an intermediate in the biosynthesis of specialized pro-resolving mediators (SPMs) which are crucial in the resolution phase of inflammation. Its mechanism of action involves the modulation of inflammatory responses through its conversion to various bioactive compounds that can influence the migration and function of immune cells. In biochemical studies, 12(S)-HpEPE is utilized to explain the pathways of lipid peroxidation and to understand the complex role of oxidized fatty acids in cellular environments. By studying this compound, researchers gain insights into the oxidative processes that underpin cellular responses to inflammation and stress, thereby enhancing our understanding of the regulatory roles of oxidized lipids in maintaining cellular homeostasis and responding to physiological challenges.
