19(R)-HETE (CAS 115461-39-7)

19(R)-HETE, identified by the CAS number 115461-39-7, is a specific isomer of hydroxyeicosatetraenoic acid (HETE), a metabolite of arachidonic acid primarily produced by the action of cytochrome P450 enzymes on this essential fatty acid. As a member of the HETE family, 19(R)-HETE plays a significant role in the modulation of various biological processes, including those involving the regulation of vascular tone and cellular signaling pathways. This compound is particularly noted for its involvement in the complex balance of vasoactive mediators, contributing to the regulation of blood flow and vascular resistance. In research, 19(R)-HETE has been utilized extensively to study its effects on intracellular signaling mechanisms and its interactions with specific receptors and ion channels within vascular endothelial and smooth muscle cells. By understanding how 19(R)-HETE influences these cellular processes, researchers can explain broader physiological concepts and contribute to the foundational knowledge in fields such as biochemistry and vascular biology.
