Abstract

Fast reaction kinetics of ,•,OH with N-4-desmethylwyosine (dYt), a derivative of rare tricyclic nucleoside has been studied by pulse radiolysis. The possible initial transient radicals of ,•,OH adducts of dYt were studied by AM1 (with geometry optimization) and B3LYP/6-31G** (calculation of total energy). The radical reaction mechanism and the possible structure of OH-adducts were discussed and predicted.
