Photoexcitation of anthraquinones (AQ) in association with DNA results in DNA damage mainly at guanine residues, with products from thymine oxidation also observed. Studies of adenine oxidation will be aided by systems with an increased driving force for charge transfer, achieved by adding electron-withdrawing groups to the AQ ring. Attaching AQ derivatives to adenine via a bridge with two carbon atoms should enable
