  Structure–Activity Relationships of Benzimidazole-Based Glutaminyl Cyclase Inhibitors Featuring a Heteroaryl Scaffold

  摘要：

  Glutaminyl cyclase (hQC) has emerged as a new potential target for the treatment of Alzheimer's disease (AD). The inhibition of hQC prevents of the formation of the A beta(3(pE)-40,42) species which were shown to be of elevated neurotoidcity and are likely to act as a seeding core, leading to an accelerated formation of A beta-oligomers and fibrils. This work presents a new class of inhibitors of hQC, resulting from a pharmacophore-based screen. Hit molecules were identified, containing benzimidazole as the metal binding group connected to 1,3,4-oxadiazole as the central scaffold. The subsequent optimization resulted in benzimidazoly1-1,3,4-thiadiazoles and -1,2,3-triazoles with an inhibitory potency in the nanomolar range. Further investigation into the potential binding mode of the new compound classes combined molecular docking and site directed mutagenesis studies.

  可见光诱导的亚硫酰基对2-巯基苯并咪唑的好氧氧化脱硫

  摘要：

  发现温和的不含过渡金属的无毒需氧光氧化还原系统可实现2-巯基苯并咪唑的高效脱硫。这种可行的催化系统包括低催化剂含量的Rose Bengal作为光敏剂，以及廉价的无毒NaCl（催化量）作为添加剂，并与氧气气氛相结合。该方案提供了重要的替代途径，可以以通常的高收率获得各种苯并咪唑和氘代苯并咪唑产品，并且对各种合成和药学上有用的功能具有良好的耐受性。机理研究表明，单电子转移和能量转移都可能在初始步骤发生，并且亚硫酰基自由基中间体参与了关键的脱硫过程。

  A library of 53 benzimidazole derivatives, with substituents at positions 1, 2 and 5, were synthesized and screened against a series of reference strains of bacteria and fungi of medical relevance. The SAR analyses of the most promising results showed that the antimicrobial activity of the compounds depended on the substituents attached to the bicyclic heterocycle. In particular, some compounds displayed

  合成了53个苯并咪唑衍生物的文库，它们在1、2和5位具有取代基，并针对一系列与医学相关的细菌和真菌参考菌株进行了筛选。SAR分析最有前景的结果表明，化合物的抗菌活性取决于与双环杂环相连的取代基。特别是，某些化合物对两种耐甲氧西林的金黄色葡萄球菌（MRSA）菌株表现出抗菌活性，其最低抑制浓度（MIC）与广泛使用的环丙沙星药物相当。这些化合物具有一些共同特征。三个具有5-卤素取代基；两个是（S）-2-乙胺苯并咪唑的衍生物；其他是一种2-（氯甲基）-1H-苯并[d]咪唑和（1H-苯并[d]咪唑-2-基）甲硫醇的衍生物。抗真菌筛选的结果也非常有趣：23种化合物对选定的真菌菌株显示出有效的杀真菌活性。它们的MIC值显示出比两性霉素B相同或更高的效力。5-卤代苯并咪唑衍生物被认为是有前途的广谱抗微生物候选物，值得进一步研究以用于潜在的治疗应用。
