  Novel pyridobenzimidazole derivatives exhibiting antifungal activity by the inhibition of β-1,6-glucan synthesis

  摘要：

  Based on the HTS hit compound 1a, an inhibitor of beta-1,6-glucan synthesis, we synthesized novel pyridobenzimidazole derivatives and evaluated their antifungal activity. Among the compounds synthesized, we identified the potent compound 15e, which exhibits excellent activity superior to fluconazole against both Candida glabrata and Candida krusei. From the SAR study, we revealed essential moieties for antifungal activity. (c) 2010 Elsevier Ltd. All rights reserved.

  吡啶并[1,2-a]苯并咪唑类药物可有效对抗结核病 (TB)、耐多药 (MDR) 结核病和广泛耐药 (XDR) 结核病

  摘要：

  抗击结核病的斗争还远未结束。结核病由结核分枝杆菌引起，是全世界最致命的感染之一。人类免疫缺陷病毒（HIV）的合并感染以及耐多药结核病（MDR-TB）和广泛耐药结核病（XDR-TB）菌株的出现进一步加重了该病的负担。在此，我们报告了2-(4-氯苄基)-3-甲基-1-氧代-1 H ,5 H -吡啶并[1,2- a ]苯并咪唑-4-甲腈作为有效抗结核药物的发现及其结构该分子的修饰导致类似物具有更高的效力和更低的毒性。许多这些衍生物在亚微摩尔浓度下也具有对抗耐药结核菌株的活性，并且对 Vero 细胞没有明显的毒性，从而强调了它们作为开发新抗结核药物的新型支架的价值。

  The struggle against tuberculosis (TB) is still far from over. TB, caused by Mycobacterium tuberculosis, is one of the deadliest infections worldwide. Co‐infection with human immunodeficiency virus (HIV) and the emergence of multidrug‐resistant tuberculosis (MDR‐TB) and extensively drug‐resistant tuberculosis (XDR‐TB) strains have further increased the burden for this disease. Herein, we report the
