  • A new route to the antitumour drug temozolomide, but not thiotemozolomide

    Interaction of 5-aminoimidazole-4-carboxamide with alkyl isocyanates yields N-substituted 1-carbamoylimidazoles which can be cyclised to imidazo[5,1-d][1,2,3,5]tetrazin-4(3H)-ones, including temozolomide 3a, on nitrosation; a similar reaction with methyl isothiocyanate, followed by nitrosation, affords the nitrosomethylamino derivative 11 of a new ring-system, imidazo[1,5-b][1,2,4]thiadiazole.

  • A15N NMR investigation of a series of benzotriazinones and related antitumour heterocycles
    作者:Keith Vaughan、Derry E. V. Wilman、Richard T. Wheelhouse、Malcolm F. G. Stevens
    DOI:10.1002/mrc.994
    日期:2002.4
    A series of 3‐substituted 1,2,3‐benzotriazin‐4‐ones, 1 and 2, were synthesized by standard methods and the 15N NMR spectra were recorded. All spectra were obtained using the natural abundance of the nitrogen‐15 isotope. The chemical shifts appear in the normal range for N‐1, N‐2 and N‐3 of the triazine ring, and also correlate with the chemical shifts in the spectra of the imidazolotriazinone, 4, and
    通过标准方法合成了一系列 3-取代的 1,2,3-苯并三嗪-4-酮,1 和 2,并记录了 15N NMR 光谱。所有光谱均使用氮 15 同位素的天然丰度获得。三嗪环的 N-1、N-2 和 N-3 的化学位移出现在正常范围内,并且还与咪唑三嗪酮 4 和咪唑并四嗪酮 5 光谱中的化学位移相关。 1a、2 和 4 的光谱,用完整的 NOE 记录,显示分配给 N-3 的单线态的反转,证明这些化合物以所示的互变异构形式存在。15N NMR 分析证实了 4-亚基苯并三嗪酮 (3) 的结构。光谱显示了带有 NH 的亚基氮原子的信号,它是 NOE 光谱中的倒置单线态,而来自 3 的 N-3 原子的信号在 NOE 光谱中没有反转。版权所有 © 2002 John Wiley & Sons, Ltd.
  • Synthesis of 2-Deoxy-β-D-ribonucleosides and 2,3-Dideoxy-β-D-pentofuranosides on Immobilized Bacterial Cells
    作者:Ivan Votruba、Antonín Holý、Hana Dvořáková、Jaroslav Günter、Dana Hocková、Hubert Hřebabecký、Tomas Cihlar、Milena Masojídková

    Alginate gel-entrapped cells of auxotrophic thymine-dependent strain of E. coli catalyze the transfer of 2-deoxy-D-ribofuranosyl moiety of 2'-deoxyuridine to purine and pyrimidine bases as well as their aza and deaza analogs. All experiments invariably gave β-anomers; in most cases, the reaction was regiospecific, affording N9-isomers in the purine and N1-isomers in the pyrimidine series. Also a 2,3-dideoxynucleoside can serve as donor of the glycosyl moiety. The acceptor activity of purine bases depends only little on substitution, the only condition being the presence of N7-nitrogen atom. On the other hand, in the pyrimidine series the activity is limited to only a narrow choice of mostly short 5-alkyl and 5-halogeno uracil derivatives. Heterocyclic bases containing amino groups are deaminated; this can be avoided by conversion of the base to the corresponding N-dimethylaminomethylene derivative which is then ammonolyzed. The method was verified by isolation of 9-(2-deoxy-β-D-ribofuranosyl) derivatives of adenine, guanine, 2-chloroadenine, 6-methylpurine, 8-azaadenine, 8-azaguanine, 1-deazaadenine, 3-deazaadenine, 1-(2-deoxy-β-D-ribofuranosyl) derivatives of 5-ethyluracil, 5-fluorouracil, and 9-(2,3-dideoxy-β-D-pentofuranosyl)hypoxanthine, 9-(2,3-dideoxy-β-D-pentofuranosyl)-6-methylpurine, and other nucleosides.

    藻酸盐凝胶包埋的辅助胸腺嘧啶依赖菌株大肠杆菌细胞催化2'-脱氧尿嘧啶2-脱氧-D-核糖呋喃基团转移到嘌呤嘧啶碱基以及它们的氮杂和去氮类似物。所有实验都不可避免地产生β-异构体;在大多数情况下,反应是区域特异性的,产生嘌呤中的N9-异构体和嘧啶系列中的N1-异构体。此外,2,3-二脱氧核苷酸可以作为糖基团的供体。嘌呤碱基的受体活性仅在取代上有少许影响,唯一的条件是存在N7-氮原子。另一方面,在嘧啶系列中,活性仅限于大多数短链5-烷基和5-卤代尿嘧啶生物的狭窄选择。含基的杂环碱基会发生脱作用;可以通过将碱基转化为相应的N-二甲氨基甲烯基衍生物来避免这种情况,然后进行解作用。该方法通过分离腺嘌呤鸟嘌呤、2-腺嘌呤6-甲基嘌呤8-氮杂腺嘌呤、8-氮杂鸟嘌呤、1-去氮腺嘌呤、3-去氮腺嘌呤的9-(2-脱氧-β-D-核糖呋喃基)衍生物,5-乙基尿嘧啶、5-尿嘧啶的1-(2-脱氧-β-D-核糖呋喃基)衍生物,以及9-(2,3-二脱氧-β-D-戊呋喃基)缺氧嘌呤、9-(2,3-二脱氧-β-D-戊呋喃基)-6-甲基嘌呤和其他核苷酸的验证。

    members of the purine metabolic pathway in animals, plants, and microorganisms. However, further metabolism of AICA remains elusive. Based on these results and facts, we hypothesized that plants themselves produce AHX and AOH through a pathway similar to the chemical synthesis. Herein, we demonstrate the existence of endogenous AHX and AOH and a novel purine pathway to produce them in plants.
    真菌刺激的植物生长的环或弧在世界各地都有发生。这些通常被称为“仙女环”。在2010年,我们发现了2-氮杂y杂黄嘌呤(AHX),它是一种由真菌引起的仙环现象的化合物。AHX刺激了所有测试植物的生长。本文中,我们揭示了植物中AHX的常见代谢物2-氮杂-8-氧代次黄嘌呤(AOH)的分离和结构测定。AHX是由5-咪唑-4-羧酰胺(AICA化学合成的,AHX可以通过黄嘌呤氧化酶转化为AOH。AICA是动物,植物和微生物嘌呤代谢途径的成员之一。但是,AICA的新陈代谢仍然难以捉摸。基于这些结果和事实,我们假设植物本身通过类似于化学合成的途径生产AHX和AOH。在此处,
