An efficient route to 3,4-dihydroxylphenylalanine (DOPA) and DOPA pept des was described by oxidation of L-tyrosine and L-tyrosine derivatives with 2-iodoxybenzoic acid (IBX) DOPA was obtained after ail Situ reduction of the corresponding ortho-Cl U I none with sodium dithionite. Oxidation reactions proceeded Ill good yields and high chemo- and regio-selectivity The chirality of the DOPA residue was retained under the reaction conditions The efficiency and the selectivity of the reaction were successfully tested using recyclable polymer-supported IBX (C) 2009 Elsevier Ltd.

Polyphenols Extracts from Oil Production Waste Products (OPWPs) Reduce Cell Viability and Exert Anti-Inflammatory Activity via PPAR gamma Induction in Colorectal Cancer Cells

Manuela Leo, Livio Muccillo, Laura Dugo, Roberta Bernini, Luca Santi, Lina Sabatino

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.

In vitro antioxidant and anti-inflammatory activity of an oleuropein-enriched extract obtained from olives leaves on BME-UV1 cells

Loredana Basirico, Fabio Mastrogiovanni, Nicola Lacetera, Luca Santi, Roberta Bernini, Umberto Bernabucci

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.

Laura Micheli, Laura Bertini, Agnese Bonato, Noemi Villanova, Carla Caruso, Maurizia Caruso, Roberta Bernini, Felice Tirone

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.

Passaging Primary Human Bronchial Epithelia Reduces CFTR-Mediated Fluid Transport and Alters mRNA Expression

Francesca Velotti, Roberta Bernini

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.
