Abstract Nine carbocyclic analogues of mono- and bis-lexitropsins and two analogues of pentamidine with unsubstituted N-terminal amine group were synthesized. We have investigated the cytotoxic activity of new aromatic analogues of DNA binding ligands in MCF-7 breast cancer cells and assessed their ability to act as inhibitors of topoisomerase I and II. These studies indicate that aromatic analogues of bis-netropsin contain two identical units tethered by alkyloxyl chains are a potent catalytic inhibitor of both topoisomerases and exhibit moderate cytotoxicity in MCF-7 breast cancer cells.
