Electrochemical monitoring of the interaction between anticancer drug and DNA in the presence of antioxidant.

The aim of this work is to find out the effect of antioxidant onto the interaction of DNA-anticancer drug, daunorubicin. Daunorubicin (DNR) is an anti-cancer drug which is used for the treatment of certain cancers including the treatment of leukemia. The treatments of patients, who suffer from cancer, become generally complicated if they take some antioxidant-containing supplement during chemotherapy. In this study, the interaction performance between DNR and DNA was investigated both in the presence and absence of antioxidant, caffeic acid, as the first time in the literature. Interaction performances were evaluated by observing both guanine (1.0V) and DNR (0.5V) oxidation signal in the same potential window.
