Abstract: The riboflavin-sensitized photodestruction of mitomycin C by the irradiation with near ultraviolet light was investigated. The irradiation with near ultraviolet light abruptly decomposed mitomycin C in the presence of riboflavin, but mitomycin C slowly decomposed by irradiating mitomycin C alone. The riboflavin-sensitized photodestruction of mitomycin C was suppressed by the quenchers, such as halogen and paramagnetic metal ions. Oxygen was required for the photosensitization. These results indicate that the initial reaction species in this photosensitization of mitomycin C is riboflavin in the excited triplet state and the decay of mitomycin C is caused by the photooxidation.
