Abstract:
The solution structures of 1:1 complexes of a quinacrine-netropsin hybrid molecule with the self-complementary DNA duplexes, d(CGCGAATTCGCG)2 and d(CGAATTCG)2, have been studied by one- and two-dimensional 1H NMR spectroscopy. The NOE data indicate that the acridine ring of the hybrid intercalates into the 5'-GpA step and its netropsin moiety spans the minor groove of the central AATT region.
