  摘要：

  通过构建光驱动人工酶来实现有关重要生物分子的非自然反应。本手稿报道了利用多面体低聚硅倍半氧烷（POSS）组成的网络聚合物进行三磷酸鸟苷（GTP）选择性氧化。我们合成了含有萘啶配体的水溶性 POSS 网络聚合物，可在网络内捕获 GTP，而钌配合物则可在光照射下氧化捕获的 GTP。首先，通过发射淬灭实验评估了鸟苷核苷与 POSS 网络聚合物内的萘啶配体的结合亲和力。结果表明，萘啶配体只能与 GTP 形成稳定的复合物（Ka = 5.5 × 106 M-1）。这些结果表明，只有 GTP 能被网络聚合物捕获。接着，研究了钌络合物修饰的 POSS 网络聚合物的光催化活性。结果表明，该网络聚合物在光照射下能有效分解 GTP。据我们所知，这是第一个不仅提供 GTP 选择性宿主聚合物，而且还提供光驱动 GTP 氧化人工酶的实例。

  Cytosine methylation is one of the most important epigenetic events, and much effort has been directed to develop a simple reaction for methylcytosine detection. In this paper, we describe the design of tag-attachable ligands for direct methylcytosine labeling and their application to fluorescent and electrochemical assays. The effect of the location of bipyridine substituents on the efficiency of osmium complexation at methylcytosine was initially investigated. As a result, a bipyridine derivative with a substituent at the C4 position showed efficient complexation at the methylcytosine residue of single-stranded DNA in a reaction mixture containing potassium osmate and potassium hexacyanoferrate(III). On the basis of this result, a bipyridine derivative with a tag-attachable amino linker at the C4 position was synthesized. The efficiency of metal complex formation in the presence of the osmate and the synthetic ligand was clearly changed by the presence/absence of a methyl group at the C5 position of cytosine. The succinimidyl esters of functional labeling units were then attached to the bipyridine ligand fixed on the methylcytosine. These labels attached to methylcytosine enabled us to detect the target methylcytosine in DNA both fluorometrically and electrochemically. For example, we were able to fluorometrically obtain information on the methylation status at a specific site by means of fluorescence resonance energy transfer from a hybridized fluorescent DNA probe to a fluorescent label on methylcytosine. In addition, by the combination of electrochemically labeled methylcytosine and an electrode modified by probe DNAs, a methylcytosine-selective characteristic current signal was observed. This direct labeling of methylcytosine is a conceptually new methylation detection assay with many merits different from conventional assays.
