  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。

  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.
