14S (15R) -EET

14S (15R) -EET is an endogenous epoxytrienoic acid derivative that mainly exists in rat organs. By studying its metabolic process, it was found that its stereoselective hydration and formation of chiral diols were significantly affected by epoxidase. Different 14,15-EET enantiomers showed different regions and stereochemistry of hydration reactions, among which 14 (R),15 (S) -EET showed specific hydration for C15. These findings reveal the important role of epoxidase in the metabolism of endogenous EETs, and the differences in enzyme affinity and reaction rate for individual EET enantiomers may lead to their stereoselective metabolism[1].
