  • BRIDGED ARTIFICIAL NUCLEOSIDE AND NUCLEOTIDE
    申请人:Obika Satoshi

    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。

    Oligonucleotides containing 4′-carboxy-, 4′-methoxycarbonyl-, 4′-carbamoyl-, and 4′-methylcarbamoyl-thymidines, and their 2′-methoxy, 2′-amino or 2′-acetamido analogs were prepared. Their duplex-forming ability with DNA and RNA complements was evaluated by UV melting experiments. Interestingly, 4′-carboxythymidine existing in the S-type sugar conformation was found to lead to an increase in the stability of the duplex formed with RNA complements compared to natural thymidine.

  • 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.

    Molecular docking simulations revealed that compounds 2, 7, and 8 had a comparable binding affinity to cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes. Additionally, the bridged nucleoside analogs 7 and 8 potently inhibited adenosine kinase enzyme as well, which indicates an alternate mechanistic pathway behind their anti-nociceptive action. Cytotoxic compound 6 demonstrated strong docking
