A series of hybrid molecules have been synthesized which result from the combination of a DNA sequence-specific ligand (netropsin) coupled to a DNA-interactive structural component of bleomycins (bithiazole). The DNA binding affinities as well as the cytostatic activity and their in vitro activity against a wide variety of viruses have been determined. Most of the new agents retain the DNA binding capacity of netropsin and distamycin, and force field and Pi calculations reveal the important role of the arc of curvature of these compounds in their binding to DNA. Like netropsin, the evaluated molecules did not show significant antiviral activity, but one of them demonstrated enhanced cytostatic activity against both human and murine tumor cell lines.
