  Structure Optimization of 2-Benzamidobenzoic Acids as PqsD Inhibitors for Pseudomonas aeruginosa Infections and Elucidation of Binding Mode by SPR, STD NMR, and Molecular Docking

  摘要：

  Pseudomonas aeruginosa employs a characteristic pqs quorum sensing (QS) system that functions via the signal molecules PQS and its precursor HHQ, They control the production of a number of virulence factors and biofilm formation. Recently, we have shown that sulfonamide substituted 2-benzamidobenzoic acids, which are known FabH inhibitors, are also able to inhibit PqsD, the enzyme catalyzing the last and key step in the biosynthesis of HHQ, Here, we describe the further optimization and characterization of this class of compounds as PqsD inhibitors. Structural modifications showed that both the carboxylic acid ortho to the amide and 3'-sulfonamide are essential for binding. Introduction of substituents in the anthranilic part of the molecule resulted in compounds with IC50 values in the low micromolar range. Binding mode investigations by SPR with wild-type and mutated PqsD revealed that this compound class does not bind into the active center of PqsD but in the ACoA channel, preventing the substrate from accessing the active site. This binding mode was further confirmed by docking studies and STD NMR.

  for the development of new antibacterial agents. FabH, beta-ketoacyl-ACP synthase III, is a particularly attractive target, since it is central to the initiation of fatty acid biosynthesis and is highly conserved among Gram-positive and -negative bacteria. Small molecules that inhibit FabH enzymatic activity have the potential to be candidates within a novel class of selective, nontoxic, broad-spectrum

  脂肪酸生物合成对于细菌存活至关重要。该生物合成途径的成分已被确定为开发新型抗菌剂的有吸引力的靶标。FabH，β-酮酰基-ACP合酶III，是特别有吸引力的靶标，因为它是脂肪酸生物合成起始的关键，并且在革兰氏阳性和阴性细菌中高度保守。抑制FabH酶活性的小分子有可能成为一类新型的选择性，无毒，广谱抗菌剂的候选者。利用有关这些高度保守的活性位点的晶体学结构信息和基于结构的药物设计原理，开发了苯甲酰氨基苯甲酸系列化合物作为FabH的有效抑制剂。
