    Discovery of membrane active benzimidazole quinolones-based topoisomerase inhibitors as potential DNA-binding antimicrobial agents
    摘要:
    A series of novel benzimidazole quinolones as potential antimicrobial agents were designed and synthesized. Most of the prepared compounds exhibited good or even stronger antimicrobial activities in comparison with reference drugs. The most potent compound 15m was membrane active and did not trigger the development of resistance in bacteria. It not only inhibited the formation of biofilms but also disrupted the established Staphylococcus aureus and Escherichia coli biofilms. It was able to inhibit the relaxation activity of E. coli topoisomerase IV at 10 mu M concentration. Moreover, this compound also showed low toxicity against mammalian cells. Molecular modeling and experimental investigation of compound 15m with DNA suggested that this compound could effectively bind with DNA to form a steady 15m-DNA complex which might further block DNA replication to exert the powerful bioactivities.

    摘要:
    目标:设计并制备一系列新颖的苯并咪唑基那酰亚胺衍生物,以应对不断增加的抗生素耐药性。 方法:通过氨解反应、N烷基化等方法,从商业4-溴-1,8-萘酐和邻苯二胺合成目标的新型苯并咪唑基那酰亚胺衍生物。通过双倍稀释技术在体外评估合成化合物的抗菌活性。利用UV-Vis光谱方法研究化合物10g与伤寒沙门氏菌DNA的相互作用。 结果:在这一系列中,携带2,4-二氯苯甲基基团的化合物10g相对于其他化合物表现出最佳的抗菌活性;尤其是,在与参考药物诺氟沙星(MIC = 4 μg/mL)相比较时,它对伤寒沙门氏菌表现出可比较的活性。进一步研究表明,化合物10g能有效地插入到伤寒沙门氏菌DNA中形成10g-DNA复合物,这可能与其抑制活性相关。分子对接结果表明,那酰亚胺化合物10g能通过π-π堆积与DNA六聚体双链的碱基对相互作用。此外,强活性化合物与临床药物的组合展现出比单独使用它们更好的抗菌效果,剂量更小,抗菌谱更广。值得注意的是,这些组合系统对氟康唑不敏感的红色链霉菌更为敏感。 结论:这项工作为优化苯并咪唑基那酰亚胺衍生物的结构,使其成为有效的抗菌剂提供了一个有前途的起点。

  • Discovery of Benzimidazole-Quinolone Hybrids as New Cleaving Agents toward Drug-Resistant <i>Pseudomonas aeruginosa</i> DNA

    new potential antimicrobial agents were designed and synthesized. Bioactive assays indicated that some of the prepared compounds exhibited potent antibacterial and antifungal activities. Notably, 2‐fluorobenzyl derivative 5 b (ethyl 7‐chloro‐6‐fluoro‐1‐[[1‐[(2‐fluorophenyl)methyl]benzimidazol‐2‐yl]methyl]‐4‐oxo‐quinoline‐3‐carboxylate) showed remarkable antimicrobial activity against resistant Pseudomonas
    设计并合成了一系列作为新型潜在抗菌剂的苯并咪唑-喹诺酮杂化物。生物活性测定表明,一些制备的化合物表现出有效的抗菌和抗真菌活性。值得注意的是,2-苄基衍生物5 b(乙基7--6--1-基[[1-[((2-氟苯基)甲基]苯并咪唑-2-基]甲基] -4-氧-喹啉-3-羧酸酯)对分离自感染患者的绿假单胞菌和热带假丝酵母具有显着的抗菌活性。活性分子5b不仅可以迅速杀死测试的菌株,而且对Hep-2细胞的毒性低。触发绿假单胞菌细菌耐药性的发展更加困难与针对诺氟沙星的5b相比。分子对接表明5b可以与拓扑异构酶IV-DNA复合物有效结合,并且量子化学研究从理论上阐明了化合物5b的良好抗菌活性。初步的实验反应机理探索表明,衍生物5b不能插入从耐药绿假单胞菌分离的DNA中,但能够有效切割DNA,这可能进一步阻止DNA复制,从而发挥强大的生物活性。另外,化合物5b是具有膜破坏能力的有前途的抗菌剂。

  • Novel purine benzimidazoles as antimicrobial agents by regulating ROS generation and targeting clinically resistant Staphylococcus aureus DNA groove
    作者:Ya-Nan Wang、Rammohan R. Yadav Bheemanaboina、Gui-Xin Cai、Cheng-He Zhou
    DOI:10.1016/j.bmcl.2018.03.046
    日期:2018.5
    A novel series of purine benzimidazole hybrids were designed and synthesized for the first time with the aim to circumvent the increasing antibiotic resistance. Hexyl appended hybrid 3c gave potent activities against most of the tested bacteria and fungi especially against multidrug-resistant strains Staphylococcus aureus ( MIC = 4 mu g/mL). Structure-activity relationships revealed that the benzimidazole fragment at the 9-position of purine played an important role in exerting potentially antibacterial activity. Both cell toxicity and ROS generation assays indicated that the purine derivative 3c showed low cytotoxicity and could be used as a safe agent. Molecular modeling suggested that hybrid 3c could bind with the residues of Topo IA through hydrogen bonds and electrostatic interactions. Quantum chemical studies were also performed on the target compound 3c to understand the structural features essential for activity. The active molecule 3c could effectively interact with S. aureus DNA to form 3c-DNA complex through groove binding mode, which might block DNA replication to display their powerful antimicrobial activity.
