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.

    Callistephin chloride (Standard)
    Inhibitor
    Callistephin (Pelargonidin 3-O-glucoside) chloride (Standard) is the analytical standard of Callistephin chloride (HY-W040045). This product is intended for research and analytical applications. Callistephin chloride is an anthocyanin. Callistephin chloride regulates the expression of inflammatory (reducing iNOS/TNF-α/COX-2) and apoptosis-related proteins by inhibiting p38 phosphorylation, and enhances the protective effect of Isoflurane (HY-A0134) on microglial cell damage. Callistephin chloride significantly reduces ROS levels, eliminates DPPH free radicals, protects retinal pigment epithelial cells, and inhibits lipid peroxidation. Callistephin chloride can alleviate glutamate excitotoxicity, reduce neuronal apoptosis, and protect cerebellar granule neurons. Callistephin chloride can inhibit the proliferation and metastasis of breast cancer cells by inducing apoptosis.
