Preliminary In Silico Evaluation of Extra Virgin Olive Oil-Derived Bioactive Compounds as Multi-Target-Directed Ligands in Metabolic Dysfunction-Associated Steatotic Liver Disease.

Background

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease worldwide and is driven by complex metabolic and inflammatory disturbances. Extra virgin olive oil (EVOO), a hallmark of the Mediterranean diet, contains numerous bioactive compounds that may exert beneficial effects on liver and cardiometabolic health. This preliminary study investigated the interactions of selected EVOO-derived compounds, with molecular targets implicated in MASLD using an integrated in silico approach.

Methods

Phenolic compounds, secoiridoids, fatty acids, sterols, squalene, and vitamin E were evaluated. Physicochemical properties, drug-likeness, and pharmacokinetic profiles were predicted using ADMETlab 3.0. Molecular docking analyses were performed against liver X receptors (LXRα and LXRβ), peroxisome proliferator-activated receptors (PPARα and PPARγ), hydroxymethylglutaryl-CoA reductase, cyclooxygenase-1, and cyclooxygenase-2. Binding modes were further examined by three-dimensional interaction analyses.

Results

The investigated compounds displayed heterogeneous physicochemical and pharmacokinetic profiles. Oleuropein, oleacein, and oleocanthal demonstrated the most consistent binding patterns across targets involved in lipid metabolism, inflammation, and cardiometabolic regulation. In contrast, highly lipophilic compounds, including squalene, β-sitosterol, and vitamin E, frequently achieved high docking scores but formed fewer biologically relevant interactions.

Conclusions

EVOO phenolics, particularly oleuropein, oleacein, and oleocanthal, emerged as promising multi-target modulators of MASLD-related pathways, supporting the potential role of EVOO in MASLD prevention and management.
