Quercetin’s prohibitive effective to NADPH oxidase. NADPH oxidase plays a vital role in generating ROS. On the setting of NADPH oxidase, NADPH transfers one electron to O2, then forms NADP+ and O2⋅–, and O2⋅– will transfer into H2O2 rapidly. However, Que can decrease the expression of Nox2 and ameliorate the oxidative stress.
