Abstract :In this study, the interaction of an anticancer drug, Capecitabine with DNA was investigated by electrochemical methods using carbon paste electrode insert ignore into journalissuearticles values(CPE);. The interaction of Capecitabine with single-stranded Calf thymus DNA insert ignore into journalissuearticles values(ss DNA); and double-stranded Calf thymus DNA insert ignore into journalissuearticles values(ds DNA); at electrode surface, or in solution phase was investigated by monitoring the changes at the oxidation signal of guanin base of DNA measured by differential pulse voltammetry insert ignore into journalissuearticles values(DPV); technique. Impedimetric measurements were performed by electrochemical impedance spectroscopy technique that also confirmed that ds DNA was immobilized onto the electrode surface. The detection limit insert ignore into journalissuearticles values(DL); in the case of interaction of Capecitabine with dsDNA and ssDNA interaction was calculated and found to be 17.35µg/mL and 17.12µg/mL, respectively.
