| 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 were focused on electrochemical behaviour of seven newly prepared complexes of lawsone with the second ligand represented by derivatives of pyridine, aminopyridine and pyrazole with copper(II) ions using 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)20.5H2O proved significant prooxidant properties, which may contribute to its cytotoxicity that has been demonstrated in recent literature. |
