  Synthesis of a novel 2′-deoxyuridine derivative bearing a cyanomethoxycarbonylmethyl group at C-5 position and its use for versatile post-synthetic functionalization of oligodeoxyribonucleotides

  摘要：

  A novel 2'-deoxyuridine derivative bearing a cyanomethoxycarbonylmethyl group at the C-5 position (1) was synthesized and its use was examined as a convertible nucleoside for the versatile post-synthesis functionalization of oligodeoxyribonucleotides (ODNs). The ODNs containing 1 reacted with primary monoamines such as heptylamine, histamine, and tyramine as well as di- and polyamines under mild conditions, giving the corresponding derivatized ODNs.

  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。

  A termini-free molecular beacon type of DNA bearing a novel silylated perylene and an anthraquinone both at the C-5 position of deoxyuridine residues exhibits prominent fluorescence upon mixing with complementary oligonucleotide (24- to 50-fold increase in comparison with a single-stranded state) along with one base mismatch discrimination ability.

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

  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.
