  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.

  Synthesis and Evaluation of Terbenzimidazoles as Topoisomerase I Inhibitors

  摘要：

  The synthesis and pharmacological activity of a series of terbenzimidazoles are described. The ability of these derivatives to induce DNA cleavage in the presence of topoisomerase I was evaluated in vitro. These analogs were also assayed for their cytotoxicity in RPMI 8402 cells and the camptothecin-resistant CPT-K5 cells. In addition the potential for these compounds to serve as substrates for MDR1 was also determined. Several terbenzimidazoles exhibited similar cytotoxicity against variants of human tumor cells that either overexpress MDR1 or are camptothecin-resistant.
