17r(18s) epete

17R(18S)-EpETE is an oxylipin and a cytochrome P450 metabolite of eicosapentaenoic acid. 17R(18S)-EpETE activates large-conductance calcium-activated potassium (BKCa) channels, increasing potassium current amplitude by 15-fold in isolated rat cerebral artery vascular smooth muscle cells at +60 mV at 50 nM. 17R(18S)-EpETE also exerts negative chronotropic effects in neonatal rat cardiomyocytes with an EC50 of ~1–2 nM and prevents calcium-induced increases in spontaneous beating. 17R(18S)-EpETE is therefore used in cardiovascular electrophysiology research systems to investigate ion channel modulation, lipid mediator signaling, and cardiac excitability regulation in cellular models.

(±)14(15)-EpETE, an eicosatetraenoic acid derivative containing an epoxy group, is an intestinal microbial lipid metabolite that attenuates cisplatin chemotherapy-induced nausea and vomiting in rats by inhibiting Substance P release through targeting GCG/PKA signaling and is commonly used to study inflammation and metabolism.

(±)8(9)-EpETE ((±)8,9-EEQ) is an epoxide of arachidonic acid biosynthesized by cytochrome P-450 (CYP450) epoxy synthase, which is specific for glomerular protection, dose-dependently prevents fspf-induced Palb, activation of Ca2+-activated K+ (BKCa) channels, and is used in the study of cardiovascular disease.
