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.

    3-Indolepropionic acid (Standard)
    3-Indolepropionic acid (Standard) is the analytical standard of 3-Indolepropionic acid. This product is intended for research and analytical applications. 3-Indolepropionic acid is shown to be a powerful antioxidant and has potential in the treatment for Alzheimer’s disease. In Vitro: 3-Indolepropionic acid is shown to be a powerful antioxidant and has potential in the treatment for Alzheimer’s disease. 3-Indolepropionic acid is a more potent scavenger of hydroxyl radicals than melatonin. Similar to melatonin but unlike other antioxidants, 3-Indolepropionic acid scavenges radicals without subsequently generating reactive and pro-oxidant intermediate compounds. It is also suggested that indolepropionic acid, a gut microbiota-produced metabolite, is a potential biomarker for the development of type 2 diabetes (T2D) that may mediate its protective effect by preservation of β-cell function.
