Methyl coelenterazine (Coelenterazine, 2-methyl analog) has been reported to be a superior antioxidant for cells against reactive oxygen species (ROS) such as singlet oxygen and superoxide anion. The coelenterazine derivative is membrane-permeant, nontoxic and highly reactive toward ROS. As oxidative stress is believed to be a mediator of apoptosis, methyl coelenterazine should be another important tool for studies of apoptosis.Coelenterazine products have been used to detect superoxide and peroxynitrite via chemiluminescence.<ul><li>Yellow solid soluble in MeOH or EtOH</li><li>Store at -20&deg;C and protect from light</li><li>C₂₀H₁₇N₃O₂</li><li>MW: 331.37</li></ul>
