    Synthesis of 4′,4′-C-diaminomethyl nucleoside derivative as a building block for constructing libraries via amide bond formation
    摘要:
    Preparation of the 4',4-C-diaminomethyl uridine analog starting from the commercial uridine via 4',4'-C-dihydroxymethyl uridine, 4',4'- C-bis-trifluoromethanesulfonyl oxymethyl uridine, and 4',4'-C-diazidomethyl uridine in total eight steps was achieved in 8% yield. Steric hindrance between 3'-O-TBDMS and 5'-O-triflate prevented the undesired ring closure which made the synthesis of target compound feasible. (c) 2007 Published by Elsevier Ltd.

    核糖核苷3'-磷酸二酯的裂解和异构化过程中氨基的分子内参与:在稳定的中间体中的作用
    摘要:
    双核苷3',5'-磷酸二酯模型,5'-氨基-4'-氨基甲基-5'-脱氧尿苷3',5'-胸苷,在3'-的4'-位置结合了两个氨基甲基官能团已制备了连接的核苷,并在很宽的pH范围内研究了其水解反应。发现氨基官能团可加速质子化和中性形式的磷酸二酯键的裂解和异构化。当以质子化形式存在时,3',5'-磷酸二酯键的裂解及其异构化为2',5'-键是pH无关的,并且是uridylyl-3'相应反应的50-80倍,5'-尿苷(3',5'-UpU)。生成的2',5'-异构体的裂解也被加速,尽管比3',5'-异构体的裂解少,但是回到3',5'-二酯的异构化并没有增强。当氨基去质子化时 两种异构体的裂解反应仍然与pH无关,并且比UpU与pH无关的裂解快了1000倍。有趣的是,现在2'至3'异构化比其逆反应快得多。讨论了这些反应的机理。速率加速很大程度上是由质子化的氨基与磷烷中间体的静电和氢键相互作用引起的。

    A series of 4'-substituted ribonucleoside derivatives has been prepared and evaluated for inhibition of hepatitis C virus (HCV) RNA replication in cell culture. The most potent and non-cytotoxic derivative was compound 28 (4'-azidocytidine, R1479) with an IC(50) of 1.28 microM in the HCV replicon system. The triphosphate of compound 28 was prepared and shown to be an inhibitor of RNA synthesis mediated
    制备了一系列的4'-取代核糖核苷衍生物,并评估了其在细胞培养中对丙型肝炎病毒(HCV)RNA复制的抑制作用。最有效和无细胞毒性的衍生物是化合物28(4'-叠氮基吡啶,R1479),在HCV复制子系统中的IC(50)为1.28 microM。制备了化合物28的三磷酸酯,并显示出它是由NS5B(IC(50)= 320 nM)介导的RNA合成抑制剂,NS5B是HCV编码的RNA聚合酶。有关类似物的数据已被用来对这一系列核苷的活性产生一些初步的要求。

    4'alpha-position did not show any cytotoxicity. The antiviral activities of these nucleosides against HSV-1, HSV-2, and HIV-1 in vitro were also examined. Compounds 22 and 23 showed antiviral activities against HSV-1 and HSV-2 without showing significant toxicity to the host cells (MRC-5 cells). Although almost all of the nucleosides showed anti-HIV-1 activities, they were also cytotoxic to the host cells (MT-4)
    由2'-脱氧胞苷或尿苷合成了一系列的4'α-C-支链嘧啶核苷。在2'-脱氧胞苷系列中,在4'α-位置的取代基在体外以Me(23)> CN(22)> C(symbol)CH(21)> CH =的顺序影响对L1210小鼠白血病细胞的细胞毒性。 CH(2)(19)> Et(24)> CH = CHCl(20)。然而,在4'α位具有乙炔基和氰基的尿苷和胞苷衍生物没有显示出任何细胞毒性。还检查了这些核苷在体外对HSV-1,HSV-2和HIV-1的抗病毒活性。化合物22和23显示出针对HSV-1和HSV-2的抗病毒活性,而没有显示出对宿主细胞(MRC-5细胞)的明显毒性。尽管几乎所有核苷都具有抗HIV-1活性,

    4′-(Hydroxymethyl)uridylyl-3′,5′-thymidine, an RNA model bearing an extra hydroxymethyl group at the 4′-position of the 3′-linked nucleoside, has been prepared and its cleavage and isomerization reactions studied over a wide pH range (from 0 to 12). Overall, the pH-rate profiles of these reactions were very similar to those of uridylyl-3′,5′-uridine (UpU) – only a very modest acceleration was observed
    制备了4'-(羟甲基)uridylyl-3',5'-胸腺嘧啶核苷(RNA模型,在3'-连接核苷的4'-位带有一个额外的羟甲基),并对其裂解和异构化反应进行了研究。 pH值范围广(从0到12)。总体而言,这些反应的pH速率曲线与uridylyl-3',5'-尿苷(UpU)的pH曲线非常相似-在酸性和中性条件下仅观察到非常适度的加速。显然,通过附加的羟甲基官能团的氢键辅助作用不显着。

    the cleavage of the 3′,5′‐phosphodiester linkage and its isomerization to a 2′,5′‐linkage are pH‐independent and 50–80 times as fast as the corresponding reactions of uridylyl‐3′,5′‐uridine (3′,5′‐UpU). The cleavage of the resulting 2′,5′‐isomer is also accelerated, albeit less than with the 3′,5′‐isomer, whereas isomerization back to the 3′,5′‐diester is not enhanced. When the amino groups are deprotonated
