    Synthesis of 1-Deazaadenosine Analogues of (2′→5′) ApApA
    摘要:
    Synthesis of (2'-->5')ApApA analogues containing 1-deazaadenosine at different positions is described (32-34). The approach used the phosphotriester methodology in solution and utilized 3'-O-benzoylated derivatives of the N-6-protected 5'-O-monomethoxytrityl-1-deazaadenosine as starting material.

    Potent and Selective Ligands for Adenosine Binding Sites
    摘要:
    A number of selective ligands for the different binding sites of adenosine have been synthesized and tested in several pharmacological models. The aim of these synthetic efforts is both to improve the knowledge of structure-activity relationships in the adenosine-related biological systems and to develop drugs from some of these molecules.

  • Synthesis of Nucleosides through Direct Glycosylation of Nucleobases with 5-<i>O</i>-Monoprotected or 5-Modified Ribose: Improved Protocol, Scope, and Mechanism
    作者:A. Michael Downey、Radek Pohl、Jana Roithová、Michal Hocek

    Simplifying access to synthetic nucleosides is of interest due to their widespread use as biochemical or anticancer and antiviral agents. Herein, a direct stereoselective method to access an expansive range of both natural and synthetic nucleosides up to a gram scale, through direct glycosylation of nucleobases with 5‐O‐tritylribose and other C5‐modified ribose derivatives, is discussed in detail.
    由于合成核苷广泛用作生化或抗癌和抗病毒剂,因此简化对合成核苷的获取备受关注。本文介绍了一种直接立体选择性方法,可通过将核碱基与5- O-三苯甲基核糖和其他C的直接糖基化作用,以达到克级的广泛范围的天然和合成核苷详细讨论了5-修饰的核糖衍生物。反应在改良的Mitsunobu反应条件下通过原位形成的1,2-脱水糖(称为“脱水酶”)的亲核环氧化物开环进行。描述了合成多种核苷和其他1取代核糖苷衍生物时的反应范围。另外,提供了对该关键糖基供体中间体形成的机理的见解。

    Cluster of differentiation 73 (CD73) converts adenosine 5'-monophosphate to immunosuppressive adenosine, and its inhibition was proposed as a new strategy for cancer treatment. We synthesized 5'- O-[(phosphonomethyl)phosphonic acid] derivatives of purine and pyrimidine nucleosides, which represent nucleoside diphosphate analogues, and compared their CD73 inhibitory potencies. In the adenine series
    分化簇73(CD73)将5'-单磷酸腺苷转化为免疫抑制腺苷,其抑制作用被提出作为一种新的癌症治疗策略。我们合成了嘌呤和嘧啶核苷的5'-O-[(膦酰基甲基)膦酸]衍生物,它们代表核苷二磷酸类似物,并比较了它们对CD73的抑制作用。在腺嘌呤系列中,大多数核糖修饰和1-deaza和3-deaza都是有害的,但可以容忍7-deaza。耐受尿嘧啶被N3-甲基取代,但不能被较大的基团或2-硫代取代。不容许1,2-二膦酰基-乙基修饰。N4-(芳基)烷氧基-胞嘧啶衍生物,特别是具有庞大的苄氧基取代基的化合物,显示出增强的效力。最有效的抑制剂是5' -5-氟尿苷(4l),N4-苯甲酰基胞苷(7f),N4- [O-(4-苄氧基)]胞苷(9h)和N4- [O的O-[(膦酰基甲基)膦酸]衍生物-(4-萘-2-基甲氧基)]-胞苷(9e)(在人CD73上Ki值为5-10 nM)。在两种尿苷二磷酸激活的P2Y受体亚型上

  • Atom-Specific Mutagenesis Reveals Structural and Catalytic Roles for an Active-Site Adenosine and Hydrated Mg<sup>2+</sup> in Pistol Ribozymes

    The pistol RNA motif represents a new class of selfcleaving ribozymes of yet unknown biological function. Our recent crystal structure of a pre‐catalytic state of this RNA shows guanosine G40 and adenosine A32 close to the G53–U54 cleavage site. While the N1 of G40 is within 3.4 Å of the modeled G53 2′‐OH group that attacks the scissile phosphate, thus suggesting a direct role in general acid–base
    手枪RNA基序代表了一类新的自我裂解的核酶,其生物学功能尚不清楚。我们最近对该RNA进行催化前的状态的晶体结构显示,鸟苷G40和腺苷A32靠近G53–U54裂解位点。虽然G40的N1在模拟可裂解磷酸的G53 2'-OH基团的模型Å内3.4Å之内,从而暗示了其在一般酸碱催化中的直接作用,但A32的功能尚不清楚。我们提供了来自原子特异性诱变的证据,即A32的N1和N3碱基均未参与催化。相比之下,A32的核糖2'-OH对于通过G键作为A32与G40之间的桥接单元的H键网络正确定位G40似乎至关重要。我们还发现,活动位点Mg 2+的内球协调性受到破坏阳离子与G33的N7结合会使核酶急剧变慢。提出了一种机制性的建议,其中A32发挥结构作用,而水合Mg 2+在裂解中起催化作用。

    A more convenient synthetic route to 1-deazaadenosine (1) by reduction of the new nucleoside 7-nitro-3-beta-D-ribofuranosyl-3H-imidazo[4,5-b]pyridine (6) is reported. Compound 6 was obtained by reaction of 7-nitroimidazo-[4,5-b]pyridine with 1,2,3,5-tetra-O-acetyl-beta-D-ribofuranose in the presence of stannic chloride followed by treatment with methanolic ammonia. 1-Deazaadenosine (1) showed good activity
