  • Title: Development of the excimer probe responsible for DNA target bearing the silylated pyrenes at base moiety.

    Journal: Bioorg Med Chem Lett; 2014 Sep 15; 24(18):4372-4375. PubMed ID: 25176188.
    Abstract:
    For the development of the excimer probe responsible for DNA target, the deoxyuridine phosphoramidite derivative bearing the silylated pyrene attached at the C-5 position was prepared and incorporated into oligonucleotides. The modified oligonucleotides showed the excimer emission in the absence of the target DNA, on the other hands, the excimer emission was quenched in the presence of the target DNA. For the utilization of the fluorescence behavior, the novel molecular beacon probe containing the silylated pyrene-modified nucleoside at the stem region was designed and the fluorescence property of the probe found to show the responsibility for DNA target.
