  Defining the Mode of Action of Tetramic Acid Antibacterials Derived from Pseudomonas aeruginosa Quorum Sensing Signals

  摘要：

  In nature, bacteria rarely exist as single, isolated entities, but rather as communities comprised of many other species including higher host organisms. To survive in these competitive environments, microorganisms have developed elaborate tactics such as the formation of biofilms and the production of antimicrobial toxins. Recently, it was discovered that the Gram-negative bacterium Pseudomonas aeruginosa, an opportunistic human pathogen, produces an antibiotic, 3-(1-hydroxydecylidene)-5-(2-hydroxyethyl)pyrrolidine-2,4-dione (C-12-TA), derived from one of its quorum sensing molecules. Here, we present a comprehensive study of the expanded spectrum Of C-12-TA antibacterial activity against microbial competitors encountered by P. aeruginosa in nature as well as significant human pathogens. The mechanism of action Of C-12-TA was also elucidated, and C-12-TA was found to dissipate both the membrane potential and the pH gradient of Gram-positive bacteria, correlating well with cell death. Notably, in stark contrast to its parent molecule 3-oxo-dodecanoyl homoserine lactone (3-oxo-C-12-HSL), neither activation of cellular stress pathways nor cytotoxicity was observed in human cells treated with C-12-TA. Our results suggest that the QS machinery of P. aeruginosa has evolved for a dual-function, both to signal others of the same species and also to defend against host immunity and competing bacteria. Because of the broad-spectrum antibacterial activity, established mode of action, lack of rapid resistance development, and tolerance by human cells, the C-12-TA scaffold may also serve as a new lead compound for the development of antimicrobial therapeutics.

  细菌群体感应和生物膜形成的小分子抑制剂

  摘要：

  细菌在称为群体感应的过程中使用小分子（或自诱导剂）监测其局部种群密度。在这里，我们报告了一种新的、有效的天然细菌自体诱导剂 [N-酰基 l-高丝氨酸内酯 (AHL)] 的合成途径，该途径易于合成类似物。该路线已应用于非天然 AHL 库的首次合成。在细菌报告基因和生物膜测定中对这些化合物的评估揭示了一组有效的群体感应拮抗剂。这些配体将作为有价值的新工具来探索群体感应在细菌发病机制中的作用。

In this Letter we report robust routes for the synthesis of a range of N-acylated-l-homoserine lactone (AHL) quorum sensing molecules. Crucially, we have analysed the enantiopurity of the final AHLs and in all cases, excellent levels were observed.

  pathogenesis. Present analytical methods for identification and quantification of AHL require time-consuming sample preparation steps and are hampered by the lack of appropriate standards. By aiming at a fast and straightforward method for AHL analytics, we investigated the applicability of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Suitable MALDI matrices, including

  ñ酰基高丝氨酸内酯（AHL）是参与许多革兰氏阴性细菌群体感应的小信号分子，在生物膜形成和发病机理中起着重要作用。当前用于AHL鉴定和定量的分析方法需要耗时的样品制备步骤，并且由于缺乏适当的标准而受阻。通过针对AHL分析的快速，直接方法，我们研究了基质辅助激光解吸/电离飞行时间质谱（MALDI-TOF MS）的适用性。测试了合适的MALDI基质（包括晶体和离子液体基质），并研究了碰撞诱导解离MS / MS中不同AHL的裂解，从而提供了有关特征性标记碎片离子的信息。采用小规模的合成协议，我们建立了一种通用且具有成本效益的程序，可快速生成同位素标记的AHL标准品，而无需大量纯化即可使用，并能产生准确的标准曲线。可以在低皮摩尔范围内进行定量分析，对于不同的AHL，定量下限可达到1-5 pmol。所开发的方法已成功地用于定量的小批量培养上清液的MALDI MS分析。铜绿假单胞菌。 在新窗口中打开图像
