14S(15R)-EET	Structural Classification Ketones, Aldehydes, Acids Source classification Endogenous metabolite	Others
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 .

Marasmic acid	Structural Classification Microorganisms Antibiotics Source classification Other Antibiotics	Bacterial Fungal
Marasmic acid is a sesquiterpenoid with unsaturated dialdehyde functionality, first isolated from the Basidiomycete Marasmus conigenus. Marasmic acid has antibacterial, antifungal, cytotoxic and mutagenic activities, and its broad-spectrum activity is related to the α,β-unsaturated aldehyde group. However, its detailed biological mechanism of action has not been clarified. Previous studies have suggested that marasmic acid may exert its effects by reacting with endogenous nucleophiles or forming pyrrole derivatives. This study found that marasmic acid interferes with the membrane sensor histidine kinase MoSln1p of M. oryzae, superactivates the HOG pathway and causes cell death, indicating that its mechanism of action is different from other unsaturated dialdehyde sesquiterpenoids.
