  • Synthesis, Duplex-Forming Ability, and Nuclease Resistance of Oligonucleotides Containing a Thymidine Derivative with a 1-Oxaspiro[4.5]decane Skeleton
    作者:Takashi Osawa、Natsumi Yano、Hiroshi Aoyama、Satoshi Obika

    Chemically modified nucleic acids are essential for the therapeutic application of oligonucleotides. In this study, 6′-C-spiro-thymidine exhibiting a fixed torsion angle γ was designed, synthesized, and incorporated into oligonucleotides. The conformational analysis of the 6′-C-spiro-thymidine monomer revealed that its torsion angle γ was in the +synclinal range (approx. 60°), which is similar to that
    化学修饰的核酸对于寡核苷酸的治疗应用至关重要。在本研究中,设计、合成了具有固定扭转角γ的6′- C-螺胸苷,并将其掺入寡核苷酸中。6'- C-螺胸苷单体的构象分析表明,其扭转角γ在+向斜范围内(约60°),这与天然RNA双链体中的扭转角类似,正如预期的那样。另一方面,已知 RNA 双链体的糖构象主要是 N 型,而合成单体的糖构象是 S 型。紫外熔解分析结果表明6'- C-螺胸苷的双链体形成能力低于天然DNA。相反,6'- C-螺胸苷可以增强寡核苷酸对核酸酶的稳定性。特别地,在寡核苷酸的3'末端掺入6'- C-螺胸苷显着增加了寡核苷酸的核酸酶抗性。 全尺寸图像
  • A NEW APPROACH TO THE SYNTHESIS OF 4′-CARBON-SUBSTITUTED NUCLEOSIDES: DEVELOPMENT OF A HIGHLY ACTIVE ANTI-HIV AGENT 2′, 3′-DIDEHYDRO-3′-DEOXY-4′-ETHYNYLTHYMIDINE
    作者:Kazuhiro Haraguchi、Shingo Takeda、Masanori Sumino、Hiromichi Tanaka、Ginger E. Dutschman、Yung-Chi Cheng、Takao Nitanda、Masanori Baba
    DOI:10.1081/ncn-200059774
    日期:2005.4.1
    Oxidation of 3'-O-TBDMS-4',5'-unsaturated thymidine 3 with dimethyldioxirane (DMDO) allowed the isolation of the epoxide 4. Upon reacting with organosilicon reagents in the Presence of SnCl4, 4 underwent stereoselective ring opening to give 4'-alpha-allyl (6), 4'-alpha-(2-bromoallyl) (7), 4'-alpha(cyclopenten-3-yl) (8), and 4'-alpha-cyano (9) derivatives of thymidine. Reactions of the 3'-epimer 12 with organoaluminum reagents gave 4-alpha-methyl (13), 4'-alpha-vinyl (14), and 4'-alpha-ethynyl (15) analogues. Compounds 13-15 were transformed into corresponding 2',3'-didehydro-3'-deoxy derivatives. Evaluation of their ability to inhibit the replication of HIV in cell culture showed that 4'-ethynyl-d4T (19) is more potent and less toxic than the parent compound d4T.
