  Development of the excimer probe responsible for DNA target bearing the silylated pyrenes at base moiety

  摘要：

  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.

  Pseudo-Dumbbell-Type Molecular Beacon Probes Bearing Modified Deoxyuridine Derivatives and a Silylated Pyrene as a Fluorophore

  摘要：

  我们最近报告了一种新型伪哑铃型分子探针（探针1），它由聚胺连接的脱氧尿苷（U）和硅化的芘组成。探针在单独存在时显示出较弱的荧光信号。在存在互补DNA的情况下，探针的荧光信号增强。在本研究中，我们制备了新的分子探针，探针2和探针3，它们具有探针1的延长茎部分。此外，探针2中的一个U被含有蒽醌的脱氧尿苷残基（Y）替代了。在探针4中，基本上与探针1相同，但探针1环部分的一个脱氧鸟苷被探针4中的脱氧次黄嘌呤替代。在探针5中，探针3的3′末端脱氧胞苷被脱氧腺苷替代。这些探针在没有靶DNA的情况下，荧光信号有效淬灭。在所有探针中，探针3的淬灭效果最强。另一方面，在存在互补DNA的情况下，信号显著增强。探针3的信号与背景的比率最高。所有这些探针还以不同程度识别靶DNA中的单核苷酸变异。探针3的序列识别能力在所有探针中也是最高的。

  Novel fluorescent cholesterol derivatives bearing dimethyl-silylated fluorescent molecules were prepared. The derivatives exhibit markedly enhanced fluorescence compared to that of an analogous derivative bearing unmodified pyrene in living cells.

  A novel fluorescent phosphoramidite derivative of dimethylsilylated pyrene was prepared and incorporated into oligoDNA. The fluorescent oligoDNA exhibited marked fluorescent signal upon binding to the fully matched complementary DNA strand, however, the signal was strongly quenched in the single-stranded form as well as in the duplex having mismatched base pair at the terminus of the duplex-forming region.

  We have recently reported a novel pseudo-dumbbell-type molecular beacon probe (Probe 1) possessing polyamine-connected deoxyuridine (U) and silylated pyrene. The probe showed weak fluorescence signal while it stayed alone. Fluorescence signal of the probe was increased in the presence of the complementary DNA. In this study, we prepared new molecular beacons, Probe 2 and Probe 3, possessing the elongated stem portion of Probe 1. In addition, one U in Probe 2 is substituted by anthraquinone-bearing deoxyuridine residue (Y) in Probe 3. Probe 4 is essentially the same as Probe 1 but one deoxyguanosine in the loop portion of Probe 1 is substituted by deoxyinosine in Probe 4. In Probe 5, 3′-terminal deoxycytidine of Probe 3 is substituted by deoxyadenosine. The fluorescence signal of these probes is effectively quenched in the absence of target DNA. Among all, Probe 3 shows the most effective quenching. On the other hand, the signal is substantially increased in the presence of complementary DNA. The ratio of signal to background in case of Probe 3 is the highest. All these probes also recognize single nucleotide alternation in the target DNA to a different extent. The sequence recognition ability of Probe 3 is also the highest among all the probes.
