    A ribozyme with michaelase activity
    摘要:
    The ability to generate RNA molecules that can catalyze complex organic transformations not only facilitates the reconstruction and plausibility of possible prebiotic reaction pathways but is also crucial for elucidating the potential of the application of RNA catalysts in organic syntheses. Iterative RNA selection previously identified a ribozyme that catalyzes the Michael addition of a cysteine thiol to an alpha,beta-unsaturated amide. This reaction is chemically similar to the rate limiting step of the thymidylate synthase reaction, which is the corresponding reaction of a cysteine thiol to the double-bond of the uracil nucleobase. Here we provide a detailed description of the synthesis of the ribozyme substrates and the substrate oligonucleotides used for its characterization and the investigation of the background reaction. We also describe the further characterization of the ribozyme with respect to substrate specificity. We show that the thiol group of the cysteine nucleophile is essential for the reaction to proceed. When substituted for a thiomethyl group, no reaction takes place. (C) 2002 Elsevier Science Ltd. All rights reserved.

    核苷5'-膦酸酯衍生物的合成及体外稳定性
    摘要:
    核苷衍生物被大量合成和测试以研究其对血小板聚集的影响。众所周知,P2Y受体在调节血小板功能以及控制动脉粥样硬化血栓形成事件中起着重要作用。对抗P2Y 1,特别是P2Y 12受体的化合物的研究对于获得有效预防和治疗动脉血栓形成的血小板聚集抑制剂的目的引起了极大的兴趣。在这项研究中,我们介绍了合成和体外人血和大鼠肝脏匀浆中新一类核苷衍生物的代谢稳定性,特别是在核糖部分也修饰的5'-膦酸酯腺苷,肌苷,鸟苷和硫代腺苷类似物。对结果的基础上获得的,我们可以假设化合物4和18以具有在体内相对高的稳定性。

    ABSTRACT Reported is an efficient synthesis of adenyl and uridyl 5′-tetrachlorophthalimido-5′-deoxyribonucleosides, and guanylyl 5′-azido-5′-deoxyribonucleosides, which are useful in solid-phase synthesis of phosphoramidate and ribonucleic guanidine oligonucleotides. Replacement of 5′-hydroxyl with tetrachlorophthalimido group was performed via Mitsunobu reaction for adenosine and uridine. An alternative

    Synthetic routes to 5'-azidoribonucleosides are reported for adenosine, cytidine, guanosine, and uridine, resulting in a widely applicable one-pot methodology for the synthesis of these and related compounds. The target compounds are appropriate as precursors in a variety of purposive syntheses, as the synthetic and therapeutic relevance of azido- and amino-modified nucleosides is expansive. Furthermore

    BINOL-derived CPAs, which completely overturn this stereochemical preference. The presently reported catalytic method does not require stoichiometric activators or chiral auxiliaries and enables asymmetric catalysis with readily available phosphoramidites. The method was applied to the stereocontrolled synthesis of diastereomeric dinucleotides as well as cyclic dinucleotides, which are of broad interest in
    我们报告了二核苷酸的催化立体控制合成。据我们所知,我们首次证明手性磷酸 (CPA) 催化剂在亚酰胺转移过程中控制立体中心的形成。还证明了前所未有的非对映发散平,使得能够获得任一亚磷酸酯非对映异构体。两种不同的 CPA 支架已被证明对于实现立体发散至关重要:肽包埋的磷酸酸衍生的 CPA,它增强和放大了固有的底物偏好,以及 C2 对称 BINOL 衍生的 CPA,它完全颠覆了这种立体化学偏好。目前报道的催化方法不需要化学计量的活化剂或手性助剂,并且可以使用现成的亚酰胺进行不对称催化。
