A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

DNA binding compounds, such as benzo[e] (BePI) and benzo[g] pyridoindole (BgPI) derivatives, exhibit preferential stabilization of triple helices. We report here the synthesis of a series of pyrimidine triple-helix-forming oligo-2′-deoxyribonucleotides conjugated with these molecules. BePI was coupled to the 5-position of 2′-deoxyuridine via two linkers of different sizes attached to its 11-position and placed at either the 5′-end, inside the sequence, or at both the 5′-end and the internal positions using periodate oxidation of a diol-containing oligonucleotide followed by reductive coupling with amino-linked BePI. The same BePI derivatives were also linked to the oligonucleotide chain via internucleotidic phosphorothiolate or phosphoramidate linkages. A mixture of diastereoisomers was prepared as well as separate pure Rp and Sp isomers. A BePI derivative, with two different linkers attached to its 3-position, and BgPI derivatives were also linked to the 5-position of a 2′-deoxyuridine located at either the 5′-end or inside the sequence, as well as to the beta- anomeric position of an additional 2′- deoxyribose placed inside the sequence. The binding properties of these oligonucleotide-benzopyridoindoles conjugates with their double-stranded DNA target was studied by absorption spectroscopy.
