    Synthesis of 5'-O-Amino-2'-Deoxypyrimidine and Purine Nucleosides: Building-Blocks for Antisense Oligonucleotides
    摘要:
    An efficient synthesis of 5'-O-amino-2'-deoxy analogs of uridine 1, thymidine 2, cytidine 3, 5-methylcytidine 3a, adenosine 4, and guanosine 5 was accomplished. The key step of 5'-O-N-bond formation in 2'-deoxynucleosides 1-5 was achieved via a Mitsunobu reaction in excellent yields. The 5'-O-amino nucleosides 1-5 are useful building-blocks for the synthesis of nucleoside dimers linked by a methylene(methylimino) (MMI) bridge. MMI is a novel phosphate surrogate for antisense oligonucleosides.

  • Selective Cleavage of O-(Dimethoxytrityl) Protecting Group with Sodium Periodate
    作者:Dominik Rejman、Šárka Králíková、Zdeněk Točík、Radek Liboska、Ivan Rosenberg
    DOI:10.1135/cccc20020502
    日期:——

    Sodium periodate in aqueous organic solvents selectively removes, under mild reaction conditions, the O-(dimethoxytrityl) protecting group. Selectivity of the cleavage was studied using the nucleoside derivatives protected by various types of groups commonly used in nucleoside and nucleotide chemistry.

    在水有机溶剂中,过碘酸钠在温和的反应条件下选择性地去除了O-(二甲氧基三苯甲基)保护基团。利用核苷衍生物进行了裂解的选择性研究,这些核苷衍生物受到核苷和核苷酸化学中常用的各种基团的保护。
  • The influence of the purine 2-amino group on DNA conformation and stability-II
    作者:Barbara L. Gaffney、Luis A. Marky、Roger A. Jones

    日期:1984.1
    Synthesis of an N-protected derivative of 2-amino-2'-deoxyadenosine (dA') from 2'-deoxyguanosine is reported. The syntheses of several oligodeoxynucleotides containing this modified nucleoside are described, together with physical characterization via melting studies and CD conformational analysis. As expected, the 2-amino group is seen to add to the duplex stability. Although the sequence d(TA')3
    据报道,由2'-脱氧鸟苷合成了N-保护的2-氨基-2'-脱氧腺苷(dA')衍生物。描述了几种含有这种修饰核苷的寡聚脱氧核苷酸的合成,以及通过熔解研究和CD构象分析的物理表征。如所预期的,看到2-氨基基团增加了双链体的稳定性。尽管发现序列d(TA')3经历了盐诱导的构象转变,但是诸如d(CGTA'CG)的混合序列却没有表现出这种行为。这些序列中存在的所有鸟嘌呤残基均为O 6用氰基乙基或4-硝基苯基乙基进行保护,以消除鸟嘌呤在磷酸化和缩合反应中的降解。描述了引入和除去这些O 6保护基的方法。

  • Independent Generation of 5-(2‘-Deoxycytidinyl)methyl Radical and the Formation of a Novel Cross-Link Lesion between 5-Methylcytosine and Guanine
    作者:Qibin Zhang、Yinsheng Wang

    日期:2003.10.1
    toward hydroxyl radical and the similar orientation of adjacent thymine guanine (TG) and 5-methylcytosine guanine (mCG) in B-DNA, we predict that the cross-link lesion, which was identified in TG and has a covalent bond formed between the 5-methyl carbon atom of T and the C8 carbon atom of G, should also form at mCG site. Here, we report for the first time the independent generation of 5-(2'-deoxycytidinyl)methyl
    活性氧 (ROS) 会损伤 DNA。尽管已经在结构上表征了许多由 ROS 诱导的单核碱基损伤,但只有少数链内交联损伤被鉴定和表征,并且所有这些损伤都涉及相邻的胸腺嘧啶和鸟嘌呤或腺嘌呤。在哺乳动物细胞中,CpG 位点的胞嘧啶被甲基化。基于 5-甲基胞嘧啶和胸腺嘧啶对羟基自由基的相似反应性以及 B-DNA 中相邻胸腺嘧啶鸟嘌呤 (TG) 和 5-甲基胞嘧啶鸟嘌呤 (mCG) 的相似取向,我们预测交联病变,在 TG 中鉴定出并在 T 的 5-甲基碳原子和 G 的 C8 碳原子之间形成共价键,也应在 mCG 位点形成。在这里,我们首次报道了 5-(2'-deoxycytidinyl)methyl 自由基的独立产生,我们的结果表明,这种自由基可以在双核苷单磷酸 d(mCG) 和 d(GmC) 中引起预测的新型链内交联损伤。此外,我们表明交联病变也可以在 d(mCG) 中从厌氧条件下的伽马辐射中形成。

    1,1,1,3,3,3-Hexafluoro-2-propanol is introduced as a suitable reagent and solvent for the detritylution of 5′-O-(4,4′-dimethoxytrityl)-nucleosides and -deoxynucleosides, especially those that are susceptible to N-glycosyl cleavage under more strongly acidic conditions.
