formylamino analogue 3 has been examined by high-resolution 1H-NMR and molecular modeling. Either ligand binds to DNA in one-drug and symmetric two-drug modes at low drug:DNA ratios, while at high ratios only the two-drug complex was observed. In this article, the structure of 2:1 drugs DNA complexes has been studied by NMR and molecular modeling, which indicate that the two analogues bind the DNA in a similar
