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.

    Landiolol hydrochloride
    		Inhibitor 99.96%
    Landiolol (ONO1101) hydrochloride is a highly selective, ultra-short-acting competitive inhibitor of β1 adrenergic receptors. Landiolol hydrochloride specifically blocks cardiac β1 receptors, reducing heart rate and myocardial oxygen consumption. Landiolol hydrochloride inhibits TNF-α-induced excessive mitochondrial oxygen consumption and reactive oxygen species production in a sepsis model, alleviating renal injury. Landiolol hydrochloride has little effect on cardiac ion channels (such as L-type calcium current and inward rectifier potassium current) and has a weak negative inotropic effect. Landiolol hydrochloride can be used for perioperative tachycardia control and protection studies of sepsis-related acute kidney injury.
