| Abstract: | One-electron oxidation of N-4-desmethylwyosine (dYt), a derivative of rare tricyclic nucleoside wyosine with several oxidative radicals, has been studied by using pulse radiolysis. The transient spectra of the radicals dYt˙+ and dYt(-H)˙ and the pK a of the radical cation were measured. The rate constants of reactions of dYt with SO 4 ˙? and CO 3 ˙? radicals have been determined and related reaction mechanisms were discussed. |
