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.

    Hesperetin
    		99.12%
    Hesperetin is a natural flavanone that can be found in citrus, and acts as a potent and orally active broad-spectrum inhibitor against human UGT activity. Hesperetin induces apoptosis via p38 MAPK activation. Hesperetin displays a range of bioactivities including antioxidant, anti-inflammatory, and anti-cancer. Hesperetin is found to induce cell-cycle arrest at G2/M phase. Hesperetin can reduce Bcl-2 and enhance BaxM. Hesperetin induces apoptosis through inhibiting NF-κB receptor.
