  Molecular Recognition of DNA by Hoechst Benzimidazoles: Exploring Beyond the Pyrrole-Imidazole-Hydroxypyrrole Polyamide-Pairing Code

  摘要：

  A series of three-ring analogs of the minor-groove-binding molecule Hoechst 33258 (1), consisting of benzimidazole (B), imidazopyridine (P), and hydroxybenzimidazole (H) monomers, have been synthesized in order to investigate both their sequence specificity and binding modes. MPE.Fe-II Footprinting has revealed the preference of both PBB and BBB ligands for 5'-WGWWW-3' and 5'-WCWWW-3' tracts, as well as A T-rich sequences. Affinity-cleavage titrations show no evidence for a 2:1 binding mode of these Hoechst analogs. Importantly, all derivatives are oriented in one direction at each of their binding sites. The implications of these results for the design of minor-groove-binding small molecules is discussed.
