Description Metal complexes of fungal and plant secondary metabolites are in the centre of interest, especially due to their biological properties including cytotoxicity. In our work, we focused on electrochemical behaviour of seven newly prepared ternary copper(II) complexes of lawsone with additional O-donor (water) and N-donor ligands (pyridine, 2-, 3-, and 4-aminopyridine, 3-hydroxypyridine, and 3,5-dimethylpyrazole) using the methods of cyclic voltammetry and differential pulse voltammetry. In addition, we tested ability of these complexes to interact with DNA. Our results indicate that the most simple complex of lawsone - Cu(lawsone)(2)(H2O)(2)center dot 0.5H(2)O proved significant prooxidant properties, which may contribute to its cytotoxicity that has been demonstrated in recent literature. In addition, all complexes evidenced ability to interact with dsDNA. In article, possible mechanisms of these interactions are discussed.
