Tempone | 97.01% | Tempone (4-Oxo-Tempo) is a nitroxide radical spin label and ROS scavenger. Tempone induces cytotoxicity in lymphoma cells. Tempone serves as a substrate for intracellular reduction to hydroxylamine, rapidly equilibrates between intracellular and extracellular compartments, reduces nitroxide radical spin labels at the ubiquinol site of the respiratory chain, and acts as an alternative terminal electron acceptor when electron flow to oxygen is blocked. Tempone serves as a superoxide sensor, a T2-weighted MRI contrast agent, and a dynamic nuclear polarization polarizing agent for 13C. Tempone inhibits superoxide and peroxynitrite, hydroxyl radical generation, nitrotyrosine formation, and poly (ADP-ribose) formation, and alleviates renal dysfunction and injury in ischemia/reperfusion and hydrogen peroxide-induced injury. Tempone can be used for research on ischemia-reperfusion injury, acute renal failure, and lymphoma. | ||||||||||||||||||||
