    Fingerprints of Modified RNA Bases from Deep Sequencing Profiles
    摘要:
    Posttranscriptional modifications of RNA bases are not only found in many noncoding RNAs but have also recently been identified in coding (messenger) RNAs as well. They require complex and laborious Methods to locate, and many still lack methods for localized detection. Here we test the ability of next-generation sequencing (NGS) to detect and distinguish between ten modified bases in synthetic RNAs. We compare ultradeep sequencing patterns of modified bases, including miscoding, insertions and deletions (indels), and truncations, to unmodified bases in the same contexts. The data show widely varied responses to modification, ranging from no response, to high levels of mutations, insertions, deletions, and truncations. The patterns are distinct for several of the modifications, and suggest the future use of ultradeep sequencing as a fingerprinting strategy for locating and identifying modifications in cellular RNAs.

    O6-(烷基/芳烷基)鸟苷和2'-脱氧鸟苷衍生物:合成和增强氯乙基亚硝基脲抗肿瘤作用的能力。
    摘要:
    合成了一系列O6-(烷基/芳烷基)鸟苷和2'-脱氧鸟苷类似物,它们扩展到可能具有水溶性的全乙酰基和N2-乙酰基衍生物。每个都与N'-(2-氯乙基)-N- [2-(甲基磺酰基)乙基] -N'-亚硝基脲相关,以体外评估M4Beu黑色素瘤细胞增强该氯代乙基亚硝基脲的细胞毒性作用的能力。通常通过O6-烷基鸟嘌呤-DNA-烷基转移酶进行的修复而减少。结构活性分析表明,(i)苄基和4-卤代苄基是提供显着活性所需的O6-取代基,(ii)2'-脱氧鸟苷衍生物比鸟苷类似物具有更高的效力,(iii)乙酰化,尤其是在N2上位置,通常会产生具有中等能力的化合物,但可能会阻止此类核苷掺入DNA。因此,O6-(4-碘苄基)-N2-乙酰鸟苷(3b)和O6-苄基过乙酰基-2'-脱氧鸟苷(2a)以及O6-苄基-N2-乙酰鸟苷(1b)和O6-苄基-N2-乙酰基到目前为止,水溶性最高的-2'-脱氧鸟苷(2b)具有良好的特性,可用于通过静脉途径进行的进一步体内试验。

  • Kinetics and mechanism of the defluorination of 8-fluoropurine nucleosides in basic and acidic media

    protected 8-fluoroguanosine, 8-fluoroinosine and 8-fluoroadenosine derivatives were prepared by direct fluorination of acetyl-protected purine nucleosides with elemental fluorine in solvents such as chloroform, acetonitrile and nitromethane. Fluorination reactions conducted in chloroform medium gave better yields of 8-fluoropurines. The fluorination yields were slightly lower when acetonitrile or nitromethane

    The ozonation of 4-thiopyrimidine and 6-thiopurine nucleosides in presence of amines afforded selectively and under mild experimental conditions several cytidine and adenosine nucleosides. The same reaction carried out in presence of alcohols afforded O4- or O6-alkylated derivatives of the nucleosides.
