Sammanfattning

The interaction of Pt(II)(dppf)-complex, namely [Pt(dppf)(H2O)(2)](2+) with DNA was investigated by DPV and H-1-NMR techniques. The results showed that the interaction process has been characterized by changes in the electrochemical parameters of both compounds and the formation of a new anodic current peak close to the anodic current peak of the [Pt(dppf)(H2O)(2)](2+). In addition, the H-1-NMR spectra show that the coordination of Pt(II)(dppf)-complex to dsDNA occurs via N(7) of guanine. Others parameters like pH and ionic strength that affect the interaction process were also investigated.
