rare tricyclic nucleoside derivative%one-electron oxidation%pulse radiolysis%radical%transient absorption spectra
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 pKa of the radical cation were measured. The rate constants of reactions of dYt with ,,and·OH radicals have been determined and related reaction mechanisms were discussed.
