    substrate, we developed several methods to obtain 2′-O,4′-C-ethyleneguanosine derivatives with much higher yields than previously reported. These methods were also applicable for the synthesis of 2′-O,4′-C-ethyleneadenosine and 2′-O,4′-C-ethylene-5-methyluridine derivatives. Moreover, we investigated the thermodynamic benefit of DNA strands containing 2′-O,4′-C-ethyleneguanosines during duplex formation
    摘要 含有 2'-O,4'-C-乙烯核酸 (ENA) 的寡核苷酸已被证明对反义治疗非常有效。2'-O,4'-C-亚乙基鸟苷及其亚磷酰胺先前是从 3,5-di-O-benzy1-4-C-(p-tollulenesulfonyloxyethyl)-1,2-di-O-acetyl-α- D-呋喃戊糖通过糖基化,但效率有限。使用 3,5-di-O-benzy1-4-C-(2-t-butyldiphenylsilyloxyethyl)-1,2-di-O-acetyl-α-D-erythropentofuranose 作为替代底物,我们开发了几种方法来获得 2 '-O,4'-C-亚乙基鸟苷衍生物的产率比以前报道的高得多。这些方法也适用于合成 2'-O,4'-C-亚乙基腺苷和 2'-O,4'-C-乙烯-5-甲基尿苷衍生物。此外,我们研究了含有 2'-O 的 DNA 链的热力学益处,与互补 RNA 形成双链体期间的
  • Synthesis and properties of thymidines with six-membered amide bridge

    Artificial thymidine monomers possessing amide or N-methylamide bridges were designed, synthesized, and introduced into oligonucleotides. UV-melting experiments showed that these oligonucleotides preferred single-stranded RNA (ssRNA) to single-stranded DNA (ssDNA) in duplex formation. Both amide-and N-methylamide-modified oligonucleotides led to a significant increase in the binding affinity to ssRNA by up to +4.7 and +3.7 degrees C of the T-m value per modification, respectively, compared with natural oligonucleotide. In addition, their oligonucleotides showed high stability against 3'-exonuclease. (C) 2013 Elsevier Ltd. All rights reserved.

    It is an object of the present invention to provide a novel molecule for antisense therapies which is not susceptible to nuclease degradation in vivo and has a high binding affinity and specificity for the target mRNAs and which can efficiently regulate expression of specific genes. The novel artificial nucleoside of the present invention has an amide bond introduced into a bridge structure of 2′,4′-BNA/LNA. The oligonucleotide containing the 2′,4′-bridged artificial nucleotide has a binding affinity for a single-stranded RNA comparable to known 2′,4′-BNA/LNA and has an increased nuclease resistance over LNA. Particularly, it is expected to be applied to nucleic acid drugs because of its much stronger binding affinity for single-stranded RNAs than S-oligo's affinity
    本发明的目的是提供一种新型分子用于反义疗法,该分子在体内不易受核酸酶降解,并且对目标mRNA具有高结合亲和力和特异性,能够有效调节特定基因的表达。本发明的新型人工核苷酸在2′,4′-BNA/LNA的桥接结构中引入了酰胺键。含有2′,4′-桥接人工核苷酸的寡核苷酸与已知的2′,4′-BNA/LNA具有相当的单链RNA结合亲和力,并且比LNA具有更高的核酸酶抗性。特别地,由于其比S-oligo对单链RNA的结合亲和力更强,预计将被应用于核酸药物。
