  SAR Studies on Trisubstituted Benzimidazoles as Inhibitors of Mtb FtsZ for the Development of Novel Antitubercular Agents

  摘要：

  FtsZ, an essential protein for bacterial cell division, is a highly promising therapeutic target, especially for the discovery and development of new-generation anti-TB agents. Following up the identification of two lead 2,5,6-trisubstituted benzimidazoles, 1 and 2, targeting Mtb-FtsZ in our previous study, an extensive SAR study for optimization of these lead compounds was performed through systematic modification of the 5 and 6 positions. This study has successfully led to the discovery of a highly potent advanced lead 5f (MIC = 0.06 mu g/mL) and several other compounds with comparable potencies. These advanced lead compounds possess a dimethylamino group at the 6 position. The functional groups at the 5 position exhibit substantial effects on the antibacterial activity as well. In vitro experiments such as the FtsZ polymerization inhibitory assay and TEM analysis of Mtb-FtsZ treated with 5f and others indicate that Mtb-FtsZ is the molecular target for their antibacterial activity.

  新型三取代苯并咪唑，靶向 Mtb FtsZ，作为新型抗结核药物

  摘要：

  通过合理的药物设计创建了新型三取代苯并咪唑文库。大量这些苯并咪唑表现出有希望的 MIC 值在 0.5-6 μg/mL (2-15 μM) 范围内，因为它们对Mtb H37Rv 菌株具有抗菌活性。此外，五种先导化合物还对具有不同耐药性的临床Mtb菌株表现出优异的活性。所有先导化合物对 Vero 细胞均未表现出明显的细胞毒性（IC 50 > 200 μM），其以剂量依赖性方式抑制Mtb FtsZ 组装。这两种先导化合物出人意料地显示出Mtb的 GTPase 活性增强FtsZ。结果强烈表明，增加的 GTPase 活性使 FtsZ 组装不稳定，从而有效抑制 FtsZ 聚合和细丝形成。分别用先导化合物处理的Mtb FtsZ 和Mtb细胞的 TEM 和 SEM 分析强烈表明，苯并咪唑铅对抑制Mtb FtsZ 组装和 Z 环形成具有新的作用机制。

  GTPase activity of Mtb FtsZ. The result strongly suggests that the increased GTPase activity destabilizes FtsZ assembly, leading to efficient inhibition of FtsZ polymerization and filament formation. The TEM and SEM analyses of Mtb FtsZ and Mtb cells, respectively, treated with a lead compound strongly suggest that lead benzimidazoles have a novel mechanism of action on the inhibition of Mtb FtsZ assembly

  Francisella tularensis is a highly virulent pathogenic bacterium. In order to identify novel potential antibacterial agents against F. tularensis, libraries of trisubstituted benzimidazoles were screened against F. tularensis LVS strain. In a preliminary screening assay, remarkably, 23 of 2,5,6- and 2,5,7-trisubstituted benzimidazoles showed excellent activity exhibiting greater than 90% growth inhibition at 1 mu g/mL. Among those hits, 21 compounds showed MIC90 values in the range of 0.35-48.6 mu g/mL after accurate MIC determination. In ex vivo efficacy assays, four of these compounds exhibited 2-3 log reduction in colony forming units (CFU) per mL at concentrations of 10 and 50 mu g/mL. (C) 2013 Elsevier Ltd. All rights reserved.
