    Synthesis and Photochemical Behavior of the Tetrazolo Tautomer of 2-Azido-4-pyrimidinone-2′-deoxyriboside
    摘要:
    The 2-azido analogue of 2'-deoxyuridine was prepared in three steps from 2'-deoxy-2-thiouridine. The sulfur atom of the 2-thio nucleoside was methylated and then displaced by hydrazine to furnish the corresponding 2-hydrazino derivative. After diazotization, the 2-azido compound that exists as its tetrazolo tautomer was obtained. Upon UV irradiation in aqueous solution, the title compound led to isocytosine.

  • Importance of 3′-Hydroxyl Group of the Nucleosides for the Reactivity of Thymidine Phosphorylase from<i>Escherichia coli</i>
    作者:Akihiko Hatano、Aiko Harano、Masayuki Kirihara
    DOI:10.1246/cl.2006.232
    日期:2006.2
    Thymidine phosphorylase in phosphate buffer catalyzed the conversion of thymidine to unnatural nucleosides. The 3′-OH, but not the 5′-OH of ribosyl moiety is necessary to be recognized as a substrate. Thus 3′-deoxythymidine could not convert to 5-fluorouracil-2′,3′-dideoxyribose. However, 5′-deoxythymidine was converted to 5-fluorouracil-2′,5′-dideoxyribose.
    在磷酸缓冲液中,胸苷磷酸化酶催化胸苷转化为非天然核苷。核糖基的3′-羟基是被识别为底物所必需的,而5′-羟基则不是。因此,3′-去氧胸苷无法转化为5-氟尿嘧啶-2′,3′-二脱氧核糖。然而,5′-去氧胸苷可以转化为5-氟尿嘧啶-2′,5′-二脱氧核糖。

This enzyme mediates nucleobase-exchange reactions to convert unnatural nucleosides possessing a large functional group such as a fluorescent molecule, coumarin or pyrene, linked via an alkyl chain at the C5 position of uracil. 5-(Coumarin-7-oxyhex-5-yn)uracil (C4U)

    The trans-2-deoxyribosylation of 4-thiouracil (4SUra) and 2-thiouracil (2SUra), as well as 6-azauracil, 6-azathymine and 6-aza-2-thiothymine was studied using dG and E. coli purine nucleoside phosphorylase (PNP) for the in situ generation of 2-deoxy-α-D-ribofuranose-1-phosphate (dRib-1P) followed by its coupling with the bases catalyzed by either E. coli thymidine (TP) or uridine (UP) phosphorylases. 4SUra revealed satisfactory substrate activity for UP and, unexpectedly, complete inertness for TP; no formation of 2’-deoxy-2-thiouridine (2SUd) was observed under analogous reaction conditions in the presence of UP and TP. On the contrary, 2SU, 2SUd, 4STd and 2STd are good substrates for both UP and TP; moreover, 2SU, 4STd and 2’-deoxy-5-azacytidine (Decitabine) are substrates for PNP and the phosphorolysis of the latter is reversible. Condensation of 2SUra and 5-azacytosine with dRib-1P (Ba salt) catalyzed by the accordant UP and PNP in Tris∙HCl buffer gave 2SUd and 2’-deoxy-5-azacytidine in 27% and 15% yields, respectively. 6-Azauracil and 6-azathymine showed good substrate properties for both TP and UP, whereas only TP recognizes 2-thio-6-azathymine as a substrate. 5-Phenyl and 5-tert-butyl derivatives of 6-azauracil and its 2-thioxo derivative were tested as substrates for UP and TP, and only 5-phenyl- and 5-tert-butyl-6-azauracils displayed very low substrate activity. The role of structural peculiarities and electronic properties in the substrate recognition by E. coli nucleoside phosphorylases is discussed.

    对4-硫代尿嘧啶(4S-Ura)和2-硫代尿嘧啶(2S-Ura),以及6-氮杂尿嘧啶、6-氮杂胸腺嘧啶和6-氮杂-2-硫代胸腺嘧啶进行了研究,使用dG和E. coli嘌呤核苷酸磷酸化酶(PNP)进行原位生成2-脱氧-α-D-核糖呋喃糖-1-磷酸(dRib-1P),然后通过E. coli胸腺嘧啶(TP)或尿嘧啶(UP)磷酸化酶催化其与碱基的结合。4S-Ura对UP显示了令人满意的底物活性,而对TP意外地完全不活化;在UP和TP存在的类似反应条件下未观察到2'-脱氧-2-硫代尿苷(2S-Ud)的形成。相反,2S-U、2S-Ud、4S-Td和2S-Td对UP和TP都是良好的底物;此外,2S-U、4S-Td和2'-脱氧-5-氮杂胞嘧啶(Decitabine)是PNP的底物,后者的磷酸解反应是可逆的。在Tris∙HCl缓冲液中,由相应的UP和PNP催化的2S-Ura和5-氮杂胞嘧啶与dRib-1P(Ba盐)的缩合反应分别产生了27%和15%的2S-Ud和2'-脱氧-5-氮杂胞嘧啶。6-氮杂尿嘧啶和6-氮杂胸腺嘧啶对TP和UP都表现出良好的底物特性,而只有TP能识别2-硫代-6-氮杂胸腺嘧啶作为底物。对6-氮杂尿嘧啶及其2-硫代衍生物的5-苯基和5-叔丁基衍生物进行了UP和TP底物的测试,只有5-苯基和5-叔丁基-6-氮杂尿嘧啶显示出非常低的底物活性。讨论了结构特异性和电子性质在E. coli核苷酸磷酸化酶底物识别中的作用。

Our study on the synthesis of geS2Ura-containing oligonucleotides (geS2U-RNA and geS2dU-DNA) revealed fast substitution of S-geranyl moiety by methylamine (frequently used in oligonucleotide deprotection procedures) or n-butylamine, providing the corresponding N2-alkyl isocytosine (R2isoCyt) derivatives.

    S-甘氨酰化2-硫尿苷(geS2Us)是细菌tRNA中最近发现的独特的疏水修饰核苷。我们对包含geS2Ura的寡核苷酸(geS2U-RNA和geS2dU-DNA)的合成研究表明,S-香叶基部分被甲胺(经常用于寡核苷酸脱保护步骤)或正丁胺快速取代,从而提供了相应的N2-烷基异胞嘧啶( R2isoCyt)衍生物。为了将S-香叶基部分保留在DNA或RNA链中,应使用具有8 M乙醇氨的最佳脱保护方案。带有R2isoCyt杂环的低聚物(R2isoC-RNA和R2isodC-DNA)的疏水性低于相应的S2U和geS2U修饰的低聚物,而与先前报道的数据相反,geS2dU-DNA和geS2U-RNA的亲脂性明显高于亲本S2Ura寡核苷酸。热力学研究表明:(a)geS2Ura和R2isoCyt修饰的寡聚体均显示出与DNA和RNA模板相似的杂交特性,(b)R2isoCyt核碱基优先与鸟嘌呤而非DNA / DNA和RNA
