  Optimization and structure–activity relationships of a series of potent inhibitors of methicillin-resistant Staphylococcus aureus (MRSA) pyruvate kinase as novel antimicrobial agents

  摘要：

  A novel series of hydrazones were synthesized and evaluated as inhibitors of methicillin-resistant Staphylococcus aureus (MRSA) pyruvate kinase (PK). PK has been identified as one of the most highly connected 'hub proteins' in MRSA. PK has been shown to be critical for bacterial survival which makes it a potential target for development of novel antibiotics and the high degree of connectivity implies it should be very sensitive to mutations and thus less able to develop resistance. PK is not unique to bacteria and thus a critical requirement for such a PK inhibitor would be that it does not inhibit the homologous human enzyme(s) at therapeutic concentrations. Several MRSA PK inhibitors (including 8d) were identified using in silico screening combined with enzyme assays and were found to be selective for bacterial enzyme compared to four human PK isoforms (M1, M2, R and L). However these lead compounds did not show significant inhibitory activity for MRSA growth presumably due to poor bacterial cell penetration. Structure-activity relationship (SAR) studies were carried out on 8d and led us to discover more potent compounds with enzyme inhibiting activities in the low nanomolar range and some were found to effectively inhibit bacteria growth in culture with minimum inhibitory concentrations (MIC) as low as 1 mu g/mL. These inhibitors bind in two elongated flat clefts found at the minor interfaces in the homo-tetrameric enzyme complex and the observed SAR is in keeping with the size and electronic constraints of these binding sites. Access to the corresponding sites in the human enzyme is blocked. (C) 2012 Elsevier Ltd. All rights reserved.

  these compounds has hindered efforts to assess the in vivo efficacy of these MreB inhibitors. The present study further examines the structure-activity of analogs related to CBR-4830 as it relates to relative antibiotic activity and improved drug properties. These data reveal that certain analogs have enhanced antibiotic activity. In addition, we evaluated several representative analogs (9, 10, 14, 26

  MreB 是一种存在于杆状细菌中的细胞骨架蛋白，对细菌细胞分裂至关重要且高度保守。由于大多数革兰氏 (-) 细菌需要 MreB 来进行细胞分裂、染色体分离、细胞壁形态发生和细胞极性，因此它是抗菌药物发现的一个有吸引力的目标。由于 MreB 调节与临床使用中的抗生素活性无关，因此对 MreB 抑制剂的获得性耐药性也不太可能。A22 和 CBR-4830 等化合物已知会通过抑制 ATP 酶活性来破坏 MreB 功能。然而，这些化合物的毒性阻碍了评估这些 MreB 抑制剂体内功效的努力。本研究进一步检查了与 CBR-4830 相关的类似物的结构活性，因为它与相对抗生素活性和改进的药物特性有关。这些数据表明某些类似物具有增强的抗生素活性。此外，我们评估了几个有代表性的类似物（9、10、14、26和31 ) 靶向纯化的大肠杆菌MreB ( EcMreB )并抑制其 ATP 酶活性的能力。除14外，所有这些类似物作为
