  • Synthesis of the Methyl Analog of 2′-<i>O</i>,4′-<i>C</i>-Ethylene-Bridged 5-Methyluridine via Intramolecular Radical Cyclization and Properties of Modified Oligonucleotides

    The synthesis of 6′S-Me-2′-O,4′-C-ethylene-bridged 5-methyluridine (6′S-Me-ENA-T) was achieved using visible light-mediated stereoselective radical cyclization as a key step. This is the first example of a method for constructing a 2′,4′-bridged structure from a 4′-carbon radical intermediate. The 6′S-Me-ENA-T monomer was successfully incorporated into oligonucleotides, and their properties were examined
    6 'S -Me-2'- O,4'- C-乙烯桥联的5-甲基尿苷(6 'S -Me-ENA-T)的合成以可见光介导的立体选择性自由基环化为关键步骤。这是从4'-碳自由基中间体构造2',4'-桥结构的方法的第一个例子。将6 'S -Me-ENA-T单体成功地掺入寡核苷酸中,并检查了它们的性质。与相应的LNA-和ENA-修饰的寡核苷酸相比,含有6 'S -Me-ENA-T的寡核苷酸表现出对单链RNA的高度选择性杂交亲和力和优异的酶稳定性。
  • Synthesis and Properties of a Bridged Nucleic Acid with a Perhydro-1,2-oxazin-3-one Ring

    A novel derivative of 2',4'-bridged nucleic acid, named hydroxamate-bridged nucleic acid (HxNA), containing a six-membered perhydro-1,2-oxazin-3-one ring, was designed and synthesized. The introduction of a carbonyl function along with an N-O linkage in the six-membered bridged structure is the unique structural feature of the novel 2',4'-bridged nucleic acid analogue. The design was carried out to restrict the flexibility of the sugar moiety through the trigonal planarity of carbonyl function, which would improve the properties of the modification. The synthesized monomer was incorporated into oligonucleotides, and their properties were examined. The HxNA-modified oligonucleotides exhibited selectively high affinity toward complementary ssRNA. Furthermore, the nuclease resistance of the HxNA-modified oligonucleotide was found to be higher than that of the corresponding natural and 2',4'-BNA/LNA-modified oligonucleotides. Interestingly, exposure of HxNA modified oligonucleotide to 3'-exonuclease resulted in gradual opening of the bridge, which stopped further digestion. Moreover, ring-opening of only one modification at the 3'-end of the oligonucleotides was observed, even if two or three HxNA modifications were present in the sequence. The results demonstrate the strong potential of the HxNA modification as a switch for the generation of highly nuclease-resistant RNA selective oligonucleotide in situ, which could have potential applications in antisense technology.
