12(S)-HEPE (CAS 116180-17-7)

12(S)-HEPE, with the CAS number 116180-17-7, is a specific enantiomer of hydroxy-eicosapentaenoic acid derived from eicosapentaenoic acid (EPA), an essential omega-3 fatty acid commonly found in fish oils. This particular compound features a hydroxyl group positioned at the twelfth carbon in the S configuration, distinguishing it in structure and function from its R counterpart. In scientific research, 12(S)-HEPE is recognized for its role in the modulation of inflammatory processes at the molecular level. It acts as a lipid mediator, engaging in the complex interplay of signaling pathways that govern the inflammatory response. This includes influencing the activity of enzymes like cyclooxygenase and lipoxygenase, which are crucial in the metabolism of fatty acids into prostaglandins and leukotrienes—key components in the inflammatory cascade. Research utilizing 12(S)-HEPE focuses on dissecting these pathways to understand how omega-3 fatty acids contribute to the resolution of inflammation and return of tissues to homeostasis. This compound helps explain the mechanisms through which specific lipid mediators can alter cell signaling, potentially leading to changes in the expression of genes associated with inflammatory responses. Through these studies, 12(S)-HEPE provides valuable insights into the natural processes that regulate inflammation and cellular health, highlighting the complex balance maintained by bioactive lipids within biological systems.
