    摘要:
    为了拓宽基于19 F核苷酸标记的现有方法的范围,我们开发了一种新的合成方法,用于合成在(低聚)磷酸部分末端含有O到F取代的氟磷酸(低聚)核苷酸类似物,并将其评估为用于19 F NMR研究的工具。我们采用了基于磷咪唑化物化学方法的三种有效而全面的合成方法,并以四正丁基氟化铵,氟一磷酸或氟代磷酸咪唑啉作为氟源,我们制备了30多种含氟磷酸盐的核苷酸,其碱基类型不同(A,G,C,U,7米G),磷酸盐链长(从单链到四链)和其他磷酸盐修饰基团(硫代,硼烷,亚氨基,亚甲基)的存在。使用氟代磷酸咪唑啉酯作为5'-磷酸化寡核苷酸的氟代磷酸化试剂,我们还合成了寡核苷酸5'-(2-氟二磷酸酯),其可能可用作19 F NMR杂交探针。化合物经19 F NMR表征,评估为19F NMR分子探针。我们发现氟磷酸核苷酸类似物可用于监测具有各种特异性和金属离子要求的酶的活性,包括人DcpS酶,一种治疗脊髓性肌萎缩的靶标。

  • Progress in demonstrating total homochiral selection in montmorillonite-catalyzed RNA synthesis

    The Na(+)-montmorillonite-catalyzed reactions of 5'-phosphorimidazolides of nucleosides generates RNA oligomers. The question arises as to how chiral selectivity was introduced into this biopolymer from a simple chemical system. We have demonstrated homochiral selection in quaternary reactions of a racemic mixture of D,L-ImpA and D,L-ImpU on Na(+)-montmorillonite. The dimer, trimer, tetramer and pentamer
    Na(+)-蒙脱石催化的核苷5'-磷酰胺基咪唑化物反应可生成RNA低聚物。问题是如何通过简单的化学系统将手性选择性引入该生物聚合物。我们已经证明了在Na(+)-蒙脱石上D,L-ImpA和D,L-ImpU的外消旋混合物的四级反应的同手性选择。研究了二聚体,三聚体,四聚体和五聚体级分的同手性选择。通过离子交换HPLC收集产物,其末端5'-磷酸被碱性磷酸酶切割。通过反相HPLC分析这些级分,以鉴定同手性和杂手性异构体。受二聚体(63.5±0.8%)和三聚体(74.3±1.7%)的均一手性过量的鼓励,该研究扩展到了高级低聚物的分析。四元反应的四聚体和五聚体在反相柱上分别分离为26和22个异构体。它们与d-ImpA和D-ImpU在Na(+)蒙脱土上的二元反应形成的共洗脱分别显示四聚体和五聚体的92.7±2.0%和97.2±0.5%的手性。这些结果表明,Na(+)-蒙脱石不仅催化RNA的益生元合成,而且还促进同手性的选择。

  • Clay catalyzed RNA synthesis under Martian conditions: Application for Mars return samples
    作者:Prakash C. Joshi、Krishna Dubey、Michael F. Aldersley、Meaghen Sausville
    DOI:10.1016/j.bbrc.2015.04.044
    日期:2015.6
    Catalysis by montmorillonites clay minerals is regarded as a feasible mechanism for the abiotic production and polymerization of key biomolecules on early Earth. We have investigated a montmorillonite-catalyzed reaction of the 5'-phosphorimidazolide of nucleosides as a model to probe prebiotic synthesis of RNA-type oligomers. Here we show that this model is specific for the generation of RNA oligomers despite deoxy-mononucleotides adsorbing equally well onto the montmorillonite catalytic surfaces. Optimum catalytic activity was observed over a range of pH (6-9) and salinity (1 +/- 0.2 M NaCl). When the weathering steps of early Earth that generated catalytic montmorillonite were modified to meet Martian soil conditions, the catalytic activity remained intact without altering the surface layer charge. Additionally, the formation of oligomers up to tetramer was detected using as little as 0.1 mg of Na+-montmorillonite, suggesting that the catalytic activity of a Martian clay return sample can be investigated with sub-milligram scale samples.

  • Synthesis of 2'-5' linked oligouridylates in aqueous medium using the Pb2+ ion.
    作者:HIROAKI SAWAI、MASAJI OHNO
    DOI:10.1248/cpb.29.2237
    日期:——
    Oligouridylates up to the pentamer were obtained by the polymerization of uridine-5'-phosphorimidazolide in aqueous solution using Pb2+ ion catalyst. The resulting oligouridylates were fully characterized by sequential enzyme and alkaline digestions. The internucleotide linkages of the oligomers were mainly 2'-5'. The yields of the 2'-5'linked dimer, trimer, tetramer and pentamer were 14.2, 6.0, 2.0 and 0.4%, respectively.
