Abstract

According to the Cypridina chemiluminescence method for measuring rate constantsbetween superoxide (O^-₂) and antioxidants established in our previous report, the reaction constants between O^-₂ and metallo-chlorophyllins or chlorins e₆, whose oxidative stress relief activities at ischemiareperfusion were inspected, were measured by quenching experiments of chemiluminescence of a Cypridina luciferin analogue, 2-methyl-6-phenyl-3, 7-dihydroimidazo [1, 2-α] pyrazin-3-one (CLA), in 25mM buffer solutions (pH 7.0) at 25°C. The results were compared with known data in the literature, and showed that the present method can be used to measure reaction activities of antioxidative samples even if fairly unstable. The results show that oxidative stress relievers have strong antioxidative activity against in aqueous solutions.
