Chemical and electrochemical oxidation of C8-arylamine adducts of 2'-deoxyguanosine.

James S Stover1, Madalina Ciobanu, David E Cliffel, Carmelo J Rizzo.   

Abstract

The electrochemical and chemical oxidation of a series of C8-arylamine adducts of 2'-deoxyguanosine has been examined. The oxidations were found to be reversible by cyclic and square-wave voltammetry in both aqueous buffer and aprotic organic solvent. The mechanism of the oxidation in protic media was either one- or two-electron, depending on the aryl group. The chemical oxidation resulted in guanidinohydantoin and spiroiminodihydantoin rearrangement products similar to those observed for 8-oxo-7,8-dihydro-2'-deoxyguanosine.
