Hydroxytyrosol is a phenolic compound with broad spectrum and a variety of biological and pharmacological activities. Hydroxytyrosol has been reported to act as an inhibitor at various stages of cancer development, protecting DNA in cells from the effects of free radicals and ROS-destroying enzymes. Hydroxytyrosol is therefore thought to have a protective effect against cancer.
It is understood that experiments have proved that hydroxytyrosol can reduce dioxin-induced oxidative stress and DNA damage in peripheral blood monocytes and reduce morphological changes of cells. In addition, low concentration of hydroxytyrosol can not only inhibit the formation of malondialdehyde, hydrogen peroxide fatty acid and 7-ketol cholesterol, but also effectively block the trend of ERK and Akt/Pkb phosphorylation, and can inhibit the damage of DNA by ultraviolet B and benzocalpyrene.
