Oleacein

Oleacin is a phenolic compound of extra virgin olive oil and has antioxidant, anti-inflammatory, antitumor, antiproliferative, antimicrobial, cardioprotective, antiobesity and antiatherosclerotic properties. In vitro studies showed that oleacein reduces ROS production by f-MLP and PMA-stimulated neutrophils (inhibiting the release of myeloperoxidase). 5-Lipoxygenase (5-LOX) and NF-kappaB signaling inhibitor. Improves insulin sensitivity in obese mice. Dual substrate-inhibitor of catechol-O-methyltransferase. Inhibits the catalytic activities of nicotinamide N-methyltransferase, ATP-citrate lyase, lysine-specific demethylase 6A and N-methyltransferase 4.
