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.

    TPP-Ce6
    Activator
    TPP-Ce6 is a mitochondria-targeted photosensitizer formed by the ester bond conjugation of chlorophyll e6 (Ce6) with triphenylphosphine (TPP). Under light irradiation or ultrasound exposure, TPP-Ce6 generates reactive oxygen species, induces cell apoptosis, and triggers immunogenic cell death. TPP-Ce6 can serve as a component of carrier-free co-delivery systems, undergo enzyme-induced self-assembly within tumors, and modulate tumor hypoxia. TPP-Ce6 is applicable to research on breast cancer and glioblastoma.

    Mono N-desmethyl disperse polyester dark blue
    Mono N-Desmethyl Disperse Polyester Dark Blue is a bioreductive agent that is activated under hypoxic conditions. Once inside a cell, it is reduced to its active form, which generates reactive oxygen species that can damage cellular components, including DNA. This damage can lead to cell death, particularly in hypoxic cancer cells that are already under stress. It has also been shown to inhibit the activity of hypoxia-inducible factor 1 (HIF-1) , which is a key regulator of the cellular response to hypoxia.
