8-Hydroxy-2′-deoxyguanosine formation and DNA damage induced by a dinuclear manganese(IV) complex and hydrogen peroxide
Abstract
The dinuclear manganese(IV) complex [Mn2O3L2][PF6]2 exhibits high activity for 8-hydroxy-2′-deoxyguanosine formation and relaxation of pBR322 form I DNA in the presence of H2O2, where L = 1,4,7-trimethyl-1,4,7-triazacyclononane; the active species is postulated to be a unidentate peroxide adduct of the manganese(IV) complex.
