In recent years, studies on the design and synthesis of artificial nucleases with biological, structural and coordination properties have been increasing. With this study, mononuclear complex compounds were obtained with Cu(II), Ni(II) and Zn(II) transition metal ion salts of bis(acylhydrazone) ligand, which has the potential to show biological activity and has revolving atoms such as N and O in its structure. The characteristic structures of the obtained complex compounds were elucidated using various techniques such as FTIR, UV-Visible, 1H-NMR, TGA, elemental analysis and magnetic susceptibility. The DNA-binding activities of potential artificial metallonucleases, whose structures were elucidated, were investigated using the UV-visible absorption titration method. Additionally, their DNA-cleavge activities were analyzed using the agarose gel electrophoresis method. The DNA binding mode and cleavage mechanisms were determined as part of this study.. In line with the results obtained, it was determined that the binding mode between DNA and the complexes is a noncovalent interaction. It has been demonstrated that the compounds cleavage DNA both oxidatively and hydrolytically. It has been revealed that the radicals involved in DNA cleavage activity are H2O2, superoxide and hydroxyl radicals. It was revealed that the compound with the highest cleavage and bonding interaction was the Cu(II) complex, followed by Ni(II) and Zn(II) complexes.
