Biochem/physiol Actions

Eicosatetraynoic acid (ETYA) is a non-metabolizable analog of ω-6 arachidonic acid. ETYA is a strong activator of the human peroxisome proliferator-activated receptor α (PPARα). It acts as an inhibitor of lipoxygenases (LOX) and cyclooxygenases (COX).
Eicosatetraynoic acid is a lipoxygenase and cyclooxygenase inhibitor.

Epithelial Na+ channels (ENaCs) are regulated by the phospholipase A2 (PLA2) product arachidonic acid. Pharmacological inhibition of PLA2 with aristolochic acid induced a significant increase in amiloride-sensitive currents in Xenopus oocytes expressing ENaC.
