    摘要:
    开发了一种无试剂的微波辅助去羧化程序,用于羧酸功能化的双环2-吡啶酮。该新方法基于在N-甲基吡咯烷酮(NMP)中以220°C加热600秒,证明实用且非常高效,产生的去羧化2-吡啶酮几乎定量。去羧化产品和羧酸甲酯及羧酸形式的中间体2-吡啶酮被筛选以研究其对Aβ肽聚集的影响。在本研究中描述的21种2-吡啶酮中,有两种抑制了阿尔茨海默病Aβ(1–40)肽的淀粉样蛋白形成。即使在2-吡啶酮与单体Aβ肽的比率为4:1时,仍观察到了这种效果。

  • C-Terminal properties are important for ring-fused 2-pyridones that interfere with the chaperone function in uropathogenic E. coli

    Virulence-associated organelles, termed pili or fimbriae, are assembled via the highly conserved chaperone–usher pathway in a vast number of pathogenic bacteria. Substituted bicyclic 2-pyridones, pilicides, inhibit pilus formation, possibly by interfering with the active site residues Arg8 and Lys112 of chaperones in uropathogenic E. coli. In this article we describe the synthesis and evaluation of nine analogues of a biologically active pilicide. Derivatization was performed with respect to its C-terminal features and the affinities for the chaperone PapD were studied with 1H relaxation-edited NMR spectroscopy. It could be concluded that the carboxylic acid functionality and also its spatial location was important for binding. In all cases, binding was significantly reduced or even abolished when the carboxylic acid was replaced by other substituents. In addition, in vivo results from a hemagglutination assay are presented where the derivatives have been evaluated for their ability to inhibit pilus formation in uropathogenic E. coli.
    在大量致病细菌中,病毒相关细胞器(称为纤毛或缘毛,通过高度保守的伴侣-usher 途径组装而成)。取代的双环 2-吡啶酮(pilicides)可抑制柔毛的形成,这可能是通过干扰尿路致病性大肠杆菌中伴侣蛋白的活性位点残基 Arg8 和 Lys112 实现的。在这篇文章中,我们介绍了九种具有生物活性的杀菌剂类似物的合成和评估。我们对其 C 端特征进行了衍生,并利用 1H 弛豫-编辑 NMR 光谱研究了其与蛋白伴侣 PapD 的亲和力。结果表明,羧酸官能团及其空间位置对结合非常重要。在所有情况下,当羧酸被其他取代基取代时,结合力都会明显降低甚至消失。此外,本文还介绍了血凝试验的体内结果,评估了这些衍生物抑制尿路致病性大肠杆菌中柔毛形成的能力。
  • Microwave-assisted decarboxylation of bicyclic 2-pyridone scaffolds and identification of Aβ-peptide aggregation inhibitors

    A reagent-free microwave-assisted decarboxylation procedure for carboxylic acid functionalized bicyclic 2-pyridones has been developed. This new method, based on microwave heating at 220 °C for 600 seconds in N-methyl pyrrolidone (NMP), proved to be practical and very efficient, resulting in decarboxylated 2-pyridones in near-quantitative yields. The decarboxylated products and the intermediate 2-pyridones in the form of carboxylic acid methyl esters and carboxylic acids were screened for their effect on Aβ-peptide aggregation. Two out of the 21 2-pyridones described in this study inhibited amyloid formation of the Alzheimer Aβ(1–40) peptide. The effect was seen even at a 4 : 1 ratio of 2-pyridone and monomeric Aβ-peptide.
