Reactive oxygen species (ROS), such as superoxide anion (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (HO•), consist of radical and non-radical oxygen species formed by the partial reduction of oxygen. Cellular ROS are generated endogenously during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.

ROS also activates MAPK pathways by the direct inhibition of MAPK phosphatases. Through PTEN, the PI3K pathway is subject to reversible redox regulation by ROS generated by growth factor stimulation. The activation of autophagy may be a cellular defense mechanism in response to ROS.

    		Inducer 98.10%
    Hydroxytyrosol acetate is an orally active, blood-brain barrier-permeable multi-active compound with multiple effects including antibacterial, antioxidant, anti-platelet aggregation, and neuroprotective activities. Hydroxytyrosol acetate not only inhibits the growth of Vibrio by increasing bacterial membrane permeability, but also interacts with DNA and mediates supercoiled DNA relaxation. Meanwhile, Hydroxytyrosol acetate effectively reduces thrombosis and inhibits lipid oxidation by inhibiting COX activity and promoting vascular nitric oxide production. In terms of neuroprotection, Hydroxytyrosol acetate significantly alleviates neuronal apoptosis and inflammatory responses by up-regulating the expression level of ERβ, thereby improving cognitive function in Alzheimer's disease models. Hydroxytyrosol acetate has been widely used in scientific research related to Vibrio infection, arterial thrombosis, Alzheimer's disease and other related fields.
