    A Novel Method for the Synthesis of Dinucleoside Boranophosphates by a Boranophosphotriester Method
    摘要:
    2'-Deoxyribonucleoside-3'-boranophosphates (nucleotide monomers), including four kinds of nucleobases, were synthesized in good yields by the use of new boranophosphorylating reagents. We have explored various kinds of condensing reagents as well as nucleophilic catalysts for the boranophosphorylation reaction with nucleosides. In the synthesis of dinucleoside boranophosphates, undesirable side reactions occurred at the O-4 of thymine and the O-6 of N-2-phenylacetylguanine bases. To avoid these side reactions, additional protecting groups, benzoyl (Bz) and diphenylcarbamoyl (Dpc) groups, were introduced to thymine and guanine bases, respectively. As a result, the condensation reactions proceeded smoothly without any side reactions, and the dimers including four kinds of nucleobases were obtained in excellent yields. In the deprotection of the 5'-DMTr group, Et3SiH was found to be effective as a scavenger for the DMTr cation which caused a P-B bond cleavage. After removal of the other protecting groups by the conventional procedure, four kinds of dinucleoside boranophosphates were obtained in good yields.

  • An investigation of antibody acyl hydrolysis catalysis using a large set of related haptens

    observed in the catalytic activities of polyclonal antibodies elicited by the different haptens. A phosphate hapten with a phenyl ring on the side of the hapten opposite the linker elicited reproducibly high levels of polyclonal antibody catalytic activity. The other 11 haptens, most with benzyl groups on the side of the hapten opposite the linker, elicited immune responses in which catalytic activity was
    催化抗体研究的一个方面在文献中很少受到关注,涉及半抗原系统,尽管该系统具有高亲和力免疫反应,但仍无法引发抗体催化剂,并且半抗原设计类似于已知可引发催化剂的那些。我们在总共三个动物系统中研究了一系列12种磷酸盐和膦酸半抗原。在不同的半抗原引起的多克隆抗体的催化活性中观察到了巨大的和可重复的差异。在与连接子相对的半抗原侧上具有苯环的磷酸半抗原引起可再现地高水平的多克隆抗体催化活性。其他11个半抗原,大部分在与连接子相对的半抗原侧带有苄基,在所观察到的催化活性的水平以及所引发的催化剂的频率方面,产生了其中催化活性明显较弱的免疫应答。我们的结果表明,过渡态类似物半抗原结构的细微特征可以对相关半抗原中引发的抗体的催化活性产生戏剧性和可复制的影响。无论作出何种解释,由于离去基团的能力/位置或半抗原整体柔性的改变而引起的机械特性的细微变化,此处提供的综合数据表明,与半抗原连接体相对的苯基或4-硝基苯基离

    Substrate analogues of phosphatidylinositol (1) were synthesized and evaluated as potential inhibitors of the bacterial phosphatidylinositol-specific phospholipase C (PI-PLC) from Bacillus cereus. The chiral analogues of the water-soluble phospholipid substrate 5 were designed to probe the effects of varying the inositol C-2 hydroxyl group, which is generally believed to serve as the nucleophile in

C-2处的天然肌醇构型保留在不可水解的二硫代磷酸酯类似物10中。然后使用D-肌醇1-(4-硝基苯基)在连续测定法中分析这些类似物对PI-PLC的抑制作用(25)作为发色底物。确定了每种磷脂酰肌醇衍生物的动力学参数,发现它们是具有K(i)的竞争性抑制剂,如下:6,0.2mM; 10,0.6毫米;
  • GMP Synthetase: Synthesis and Biological Evaluation of a Stable Analog of the Proposed AMP-XMP Reaction Intermediate
    作者:Edward J. Salaski、Hans Maag
    DOI:10.1055/s-1999-3104
    日期:——
    The enzyme guanosine monophosphate synthetase is part of the de novo purine synthesis pathway and is responsible for the conversion of xanthosine monophosphate to guanosine monophosphate. The phosphate-linked adenyl-XMP 1 has been proposed as the intermediate in a stepwise mechanism for this conversion. Direct observation of 1; either as produced in the enzymatic reaction, or as a potential synthetic target is not readily feasible due to the high lability of the phosphate linkage. We therefore undertook the synthesis of the phosphonate 2 as a stable analog of this proposed intermediate. The successful synthetic strategy involved the coupling under Mitsunobu conditions of a 2-phosphorylmethyl inosine with an adenosine derivative. This gave 2 after deprotection and 5′ monophosphate formation of the initial coupling product. Compound 2 inhibited GMP synthetase with a Ki of 0.56 μM.
    酶鸟苷酸合成酶是新生嘌呤合成途径的一部分,负责将黄苷酸单磷酸转化为鸟苷酸单磷酸。已提出磷酸链接的腺苷-XMP 1是这一转化过程的中间体。然而,由于磷酸链接的高不稳定性,直接观察1(无论是在酶反应中产生的或作为潜在合成目标)并不容易。因此,我们进行了磷酸酯2的合成,作为这一提议中间体的稳定类似物。成功的合成策略涉及将2-磷酸甲基肌苷与腺苷衍生物在Mitsunobu反应条件下偶联。经过去保护和初始偶联产物的5′单磷酸形成后得到了化合物2。化合物2以0.56 μM的Ki值抑制了GMP合成酶。
  • Use of 2-trimethylsilylethyl as a protecting group in phosphate monoester synthesis
    作者:Akiyoshi Sawabe、Sandra A. Filla、Satoru Masamune

    demonstrated that phosphorylation of a highly hindered hydroxyl group can be achieved via sequential treatment with (1) 2-trimethylsilylethyl dichlorophosphite, (2) 2-trimethylsilylethyl alcohol, and (3) hydrogen peroxide. The resulting triester survives a variety of reaction conditions but may be cleaved with fluoride ion to afford the phosphate monoester.

  • Evolution of Catalytic Activity throughout a Polyclonal Immune Response Elicited by a Transition-State-Analog Hapten
    作者:Kevin Shreder、Richard Thomas、Michael Wallace、Eric Helms、Brent Iverson

    carried out a comprehensive study that analyzes the evolution of catalytic activity in the polyclonal antibodies elicited by a phosphate hapten over the course of an immunization regimen. We have found that catalytic activity elicited by the phosphate hapten 1, measured as apparent kcat for the hapten-specific fraction of polyclonal antibodies, increased through the first four or five immunizations, then
    我们进行了一项全面的研究,分析了在免疫方案过程中磷酸半抗原诱导的多克隆抗体中催化活性的演变。我们已经发现,由磷酸半抗原1引起的催化活性,以表观k cat表示对于多克隆抗体的半抗原特异性部分,在前四或五次免疫后均升高,然后在两只所研究的兔子中降低至不同程度。最初催化活性的增加与半抗原亲和力的增加有关,但是随后半抗原亲和力仍然很高,而催化活性在响应中随后下降。这些结果表明,在达成任何总体结论之前,必须考虑催化免疫反应的时间方面,例如,催化活性与半抗原亲和力的简单关联。另外,很明显,免疫次数是在尝试优化抗体催化活性时必须考虑的重要参数,并且更多的免疫未必会更好。
