  Triple Recognition of B-DNA by a Neomycin−Hoechst 33258−Pyrene Conjugate

  摘要：

  Recent developments have indicated that aminoglycoside binding is not limited to RNA, but to nucleic acids that, like RNA, adopt conformations similar to its A-form. We further sought to expand the utility of aminoglycoside binding to B-DNA structures by conjugating neomycin, an aminoglycoside antibiotic, with the B-DNA minor groove binding ligand Hoechst 33258. Envisioning a dual groove binding mode, we have extended the potential recognition process to include I third, intercalative moiety. Similar conjugates. which vary ill the number of binding moieties but maintain Identical linkages to allow direct comparisons to be made, have also been prepared. We report herein novel neomycin- and Hoechst 33258-based conjugates developed Ill our laboratories for exploring the recognition potential with B-DNA. Spectroscopic studies Such as UV melting, differential scanning calorimetry, isothermal fluorescence titrations, and circular dichroism together illustrate the triple recognition of the novel conjugate containing neomycin, Hoechst 33258, and pyrene. This study represents the first example of DNA molecular recognition capable of minor versus major groove recognition in conjunction with intercalation.

  Triple recognition of B-DNA

  摘要：

  A novel conjugate of Hoechst 33258, pyrene and neomycin was synthesized and examined for its binding and stabilization of A-T rich DNA duplexes using spectroscopic and viscometric techniques. The conjugate, containing three well known ligands that bind nucleic acids albeit in different binding modes, was found to significantly stabilize DNA over parent conjugates containing only one or both of the other recognition elements. The study represents the first example of DNA molecular recognition capable of minor/major groove recognition in conjunction with intercalation. (C) 2009 Elsevier Ltd. All rights reserved.
