Abstract
As a model for chemical DNA repair, reduction of guanosyl radicals in the reaction with cysteine or the dipeptide cysteine-glycine has been studied by time-resolved chemically induced dynamic nuclear polarization (CIDNP). Radicals were generated photochemically by pulsed laser irradiation of a solution containing the photosensitizer 2,2′-dipyridyl, guanosine-5′-monophosphate, and the amino
