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.

    Trimethylamine-N-oxide-13C3
    		Activator
    Trimethylamine-N-oxide-13C3 is the 13C-labeled Trimethylamine N-oxide. Trimethylamine N-oxide is a gut microbe-dependent metabolite of dietary choline and other trimethylamine-containing nutrients. Trimethylamine N-oxide induces inflammation by activating the ROS/NLRP3 inflammasome. Trimethylamine N-oxide also accelerates fibroblast-myofibroblast differentiation and induces cardiac fibrosis by activating the TGF-β/smad2 signaling pathway[1][2][3].

    Sembragiline
    Sembragiline (EVT 302) is a potent, selective and reversible monoamine oxidase B (MAO-B) inhibitor. Sembragiline reduces the metabolism of dopamine and other amine neurotransmitters by inhibiting the activity of the MAO-B enzyme, thereby potentially increasing the concentration of these neurotransmitters in the brain. Inhibition of the MAO-B enzyme also reduces the formation of toxic reactive oxygen species (ROS) that play a role in the pathological process of AD. Sembragiline has good oral activity and blood-brain barrier permeability. Sembragiline can be used in studies of AD, especially in patients with AD who show increased MAO-B activity.
