Reactive Oxygen Species (ROS)

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.

    Propoxur
    Activator 99.43%
    Propoxur is a reversible, competitive, orally active AChE inhibitor that can cross the blood-brain barrier. Propoxur inhibits AChE activity to induce neurotoxicity, while promoting MMP-2 expression and enhancing tumor cell migration and invasion by inducing intracellular ROS generation and activating the ERK/Nrf2 signaling pathway. On the one hand, Propoxur inhibits AChE, leading to acetylcholine accumulation and causing neurological dysfunction; on the other hand, it promotes Nrf2 nuclear translocation through ROS-dependent ERK1/2 phosphorylation, and upregulates MMP-2 and other invasion-related proteins. Propoxur is also a carbamate insecticide used to combat turf, forestry, and household pests.
