Summary: This report presents the synthesis and characterization of a mimic of [FeFe]-hydrogenase, named [Fe-2(CO)(6){μ-bdtf}] (2, bdtf = 3,4-dimercaptobenzaldehyde), obtained from the reaction between 3,4-dimercaptobenzaldehyde and Fe-3(CO)(12). Different ligands, such as PPh3 and P(OMe)(3), were used to modify complex 2, resulting in mono- and disubstituted complexes [Fe-2(CO)(5)PPh3{μ-bdtf}] (3), [Fe-2(CO)(4)(PPh3)(2){μ-bdtf}] (4), and [Fe-2(CO)(4)(P(OMe)(3))(2){μ-bdtf}] (5). The structures of complexes 2-5 were determined by X-ray diffraction analysis. The electrochemistry and catalytic activity of these mimics towards proton reduction were evaluated by cyclic voltammetry, with all complexes showing potential for hydrogen formation in the presence of weak acid, such as acetic acid (AcOH).

Summary: Olive oil production generates waste products rich in water-soluble polyphenols, which can pose environmental problems. However, these waste products can be exploited for their bioactive properties. This study chemically characterized the polyphenolic extracts from the waste products and investigated their biological activities in normal and colorectal cancer cells. The extracts showed anti-inflammatory effects and can potentially ameliorate inflammation associated with diseases and tumors.

Summary: This in vitro study evaluated for the first time the antioxidant and anti-inflammatory effect of an Oleuropein-enriched extract on bovine mammary epithelial cells. The extract showed no cytotoxic effect on the cells and reduced ROS production induced by hydrogen peroxide. It also downregulated the expression of pro-inflammatory cytokines. These findings confirm the antioxidant and anti-inflammatory properties of the extract.

Summary: Aging is a complex process caused by cellular damage accumulation and reduction in physiological activities, leading to increased incidence of age-related diseases. The Mediterranean diet, particularly the bioactive compounds in extra virgin olive oil like hydroxytyrosol and oleuropein, has been associated with longevity and protection against age-related disorders. This review focuses on the effects of these compounds on the brain, skeletal muscle, and gut microbiota, discussing their role in neurodegenerative diseases, neurogenesis, senescence, muscle disorders, and gut microbiota composition.

Summary: Inflammaging refers to chronic low-grade inflammation caused by immune and non-immune cells stimulated by endogenous/self, misplaced or altered molecules, belonging to physiological aging. This inflammatory status is characterized by increased inflammation and decreased autophagy, and predisposes to age-related diseases. Phenolic compounds, particularly hydroxytyrosol (HTyr) found in extra-virgin olive oil, have antioxidant and anti-inflammatory properties that may counteract inflammaging and contribute to healthy aging.
