  • Competitive inhibitors of type B ribose 5-phosphate isomerases: design, synthesis and kinetic evaluation of new d-allose and d-allulose 6-phosphate derivatives
    作者:Sandrine Mariano、Annette K. Roos、Sherry L. Mowbray、Laurent Salmon

    demonstrated to have competitive inhibition. Kinetic evaluation on Rpi activity of both EcRpiB and RpiB from Mycobacterium tuberculosis (MtRpiB) shows that several of the designed 6-carbon high-energy intermediate analogues are new competitive inhibitors of both RpiBs. One of them, 5-phospho-D-ribonate, not only appears as the strongest competitive inhibitor of a Rpi ever reported in the literature, with
    这项研究报告了D-阿洛糖6-磷酸(All6P),D-阿洛糖(或D-庚糖)6-磷酸(Allu6P)和7种D-核糖5-磷酸异构酶(Rpi)抑制剂的合成。抑制剂被设计为6碳高能中间体的类似物,该中间体被假定为由Escherichiacoli(EcRpiB)的B型Rpi催化的All6P到Allu6P异构化反应(Allpi活性)。可以通过All6P或Allu6P的氧化裂解轻松获得的5-Phospho-D-ribonate,导致了原始的合成子5-dihydrogenophospho-D-ribono-1,4-lactone,可以通过亲核加成反应从中合成其他抑制剂步。对EcRpiB的Allpi活性的动力学评估表明,这些化合物中的两个,即5-磷酸-D-核糖异羟肟酸和N-(5-磷酸-D-核糖酰基)-甲胺,​​确实起着新型的EcRpiB抑制剂的作用。进一步,已证明5-磷酸-D-核糖异羟肟酸具有竞争性抑制作用。

    The amidine bases DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) and DBN (1,5-diazabicyclo[4.3.0]non-5-ene) display nucleophilic behaviour towards highly electrophilic p-nitrophenyl carbonate derivatives with ring opening of the bicyclic ring to form corresponding substituted epsilon-caprolactam and gamma-lactam derived carbamates. This simple method presents a unified strategy to synthesize structurally

    efficient synthesis of spirocyclic triazolooxazine nucleosides is described. This was achieved by the conversion of β-D-psicofuranose to the corresponding azido-derivative, followed by alkylation of the primary alcohol with a range of propargyl bromides, obtained by Sonogashira chemistry. The products of these reactions underwent 1,3-dipolar addition smoothly to generate the protected spirocyclic adducts

    azetidinic system is described, along with two analogous phosphonate derivatives of the former. These systems were constructed from the same β-D-psicofuranose starting material. The triazole spirocyclic nucleosides were constructed using the 1-azido-1-hydroxymethyl derived sugars, where the primary alcohol was alkylated with a range of propargyl bromides, whereas the azetidine systems orginated from the corresponding
    描述了包含三唑或氮杂环丁烷系统的许多螺环核糖核苷的合成,以及前者的两种类似的膦酸酯衍生物。这些系统是由相同的β- D- psicofuranose起始原料构建的。使用1-叠氮基-1-羟甲基衍生的糖构建三唑螺环核苷,其中伯醇被一系列炔丙基溴烷基化,而氮杂环丁烷体系则由相应的1-氰基-1-羟甲基糖产生。由于它们与利巴韦林的相似性,因此使用MHV(鼠肝炎病毒)作为模型对化合物库的抗病毒特性进行了研究。
  • Conformation-specific cleavage of antisense oligonucleotide-RNA duplexes by RNase H
    作者:Pushpangadan I. Pradeepkumar、Edouard Zamaratski、András Földesi、Jyoti Chattopadhyaya
    DOI:10.1039/b006476i

    The North-form (3′-endo) constrained 1-(1′,3′-O-anhydro-β-D-psicofuranosyl)thymine block, , was systematically incorporated at various sites, one at a time, into a set of four antisense oligonucleotides (AONs). The hybrids of these AONs with a matched 15mer RNA target were subjected to the RNase H cleavage reaction, and compared with that of the native counterpart, in order to probe how far the local influence of a single North-locked sugar is transmitted in steering conformational changes in the neighbouring nucleotides. It was found that the introduction of a single North-sugar locked nucleotide in the AONs makes up to four of the neighbouring nucleotides at the 5′-end of the modification site resistant to the RNase H cleavage reaction. This suggests that a stretch of 5-nucleotides, including the nucleotide, in the AON strand adopts a North-type conformation, giving a local RNA/RNA type hybrid structure instead of a regular DNA/RNA type duplex structure. Although these 5-nucleotide regions were completely resistant to RNase H promoted hydrolysis, they could serve as the binding site for the enzyme. Interestingly, none of these local adaptations of the RNA/RNA type structure were observable by CD spectroscopy, showing it to be an unsuitable means of monitoring any subtle alteration of the local structure. This work, therefore, constitutes an example of how the engineered conformation of a substrate can be used to exploit the stereochemical sensitivity of an enzyme to map local microscopic conformational changes. The other implication of this work is that it provides a new tool to gather local structural information, which may help to optimize the number of constrained residues which need to be incorporated to induce the antisense strand to adopt either A- or B-type geometry in the hybrid duplex, with or without the loss of RNase H recognition and/or cleavage properties.
    北型(3′-内源)限制结构的1-(1′,3′-O-脱水-β-D-小学糖基)胸苷区块被系统性地逐一引入到一组四个反义寡核苷酸(AONs)的不同位置。这些AON与相匹配的15个核苷酸的RNA靶标形成的杂合体被用于RNase H裂解反应,并与其天然同类进行比较,以探讨一个北锁定糖的局部影响在多大程度上传播到邻近的核苷酸,进而引导构象变化。研究发现,在AON中引入一个北糖锁定核苷酸后,修改位点5'端的多达四个邻近核苷酸对RNase H裂解反应具有抗性。这表明,包含该核苷酸在内的AON链中的5核苷酸段采纳了北型构象,形成局部的RNA/RNA型杂合结构,而不是常规的DNA/RNA型双链结构。尽管这些5核苷酸区域完全抗拒RNase H促进的水解,它们仍然可以作为酶的结合位点。有趣的是,通过圆二色谱(CD谱)无法观察到这些RNA/RNA型结构的任何局部适应性,显示这种方法不适合监测局部结构的细微变化。因此,这项工作展示了如何利用底物的工程化构象来利用酶的立体化学敏感性,以映射局部微观构象变化。这项工作的另一个意义在于,它提供了一种新的工具来收集局部结构信息,这可能有助于优化需要引入的限制残基的数量,以诱导反义链在混合双链中采用A型或B型几何结构,而不损失RNase H的识别和/或裂解特性。
