  DPD-Inspired Discovery of Novel LsrK Kinase Inhibitors: An Opportunity To Fight Antimicrobial Resistance

  摘要：

  Antibiotic resistance is posing a continuous threat to global public health and represents a huge burden for society as a whole. In the past decade, the interference with bacterial quorum sensing (QS) (i.e., cell cell communication) mechanisms has extensively been investigated as a valid therapeutic approach in the pursuit of a next generation of antimicrobials. (S)-4,5-Dihydroxy-2,3-pentanedione, commonly known as (S)-DPD, a small signaling molecule that modulates QS in both Gram-negative and Gram-positive bacteria, is phosphorylated by LsrK, and the resulting phospho-DPD activates QS. We designed and prepared a small library of DPD derivatives, characterized by five different scaffolds, and evaluated their LsrK inhibition in the context of QS interference. SAR studies highlighted the pyrazole moiety as an essential structural element for LsrK inhibition. Particularly, four compounds were found to be micromolar LsrK inhibitors (IC50 ranging between 100 mu M and 500 mu M) encouraging further exploration of novel analogues as potential new antimicrobials.

  合成 4,5-二羟基-2,3-戊二酮 (DPD) 和相关化合物作为细菌群体感应的潜在调节剂的通用策略

  摘要：

  抗生素耐药性是对全球公共卫生的日益严重的威胁，其管理转化为巨大的医疗保健费用。验证新的革兰氏阴性抗菌目标作为潜在新抗生素的来源仍然是该领域所有科学家面临的挑战。对细菌群体感应 (QS) 机制的干扰代表了一种潜在的有趣方法来控制细菌生长和开发下一代抗菌药物。在此背景下，我们的研究重点是发现与 (S)-4,5-dihydroxy-2,3-pentanedione 结构相关的新型化合物，通常称为 (S)-DPD，一种能够调节细菌的小信号分子革兰氏阴性菌和革兰氏阳性菌中的 QS。在这项研究中，提出了外消旋 DPD 的实用且通用的合成方法。与之前报道的合成相比，所提出的策略简短而稳健：它只需要一个纯化步骤，避免使用昂贵或危险的起始材料以及特定设备的使用。因此，它非常适合用于药物研究的衍生物的合成，正如本文描述的四个系列的新型 DPD 相关化合物所证明的那样。

  in both Gram-negative and Gram-positive bacteria. In this study, a practical and versatile synthesis of racemic DPD is presented. Compared to previously reported syntheses, the proposed strategy is short and robust: it requires only one purification step and avoids the use of expensive or hazardous starting materials as well as the use of specific equipment. It is therefore well suited to the synthesis
