  Synthesis, antioxidant, and antimicrobial evaluation of some 2-arylbenzimidazole derivatives

  摘要：

  A series of 2-arylbenzimidazole derivatives (3a-3p and 4a-4i) were synthesized and evaluated as potential antioxidant and antimicrobial agents. Their antioxidant properties were evaluated by various in vitro assays including hydroxyl radical (HO center dot) scavenging, superoxide radical anion (O-2(center dot)) scavenging, 1,1-diphenyl- 2-picrylhydrazyl (DPPH) radical scavenging, and ferric reducing antioxidant power. Results demonstrated that compounds with hydroxyl group at the 5-position of benzimidazole ring had a comparable or better antioxidant activity in comparison to standard antioxidant tert-butylhydroquinone (TBHQ). Markedly, compound 4h that showed the highest HO center dot scavenging activity (EC50 = 46 mu M) in vitro had a significant reduction of 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH)-induced intracellular oxidative stress and H2O2-induced cell death. In addition, these compounds showed moderate to good inhibitory activity against Staphylococcus aureus selectively at noncytotoxic concentrations. (C) 2013 Elsevier Ltd. All rights reserved.

  A solid phase strategy for the synthesis of substituted 2-arylbenzimidazoles over silica gel has been achieved starting from their corresponding o-phenylenediamines 1 and aromatic aldehydes 2. The reaction is very simple, convenient and straightforward, and the products are obtained in moderate to high yields (49–91%).

  Arylbenzimidazoles have been synthesized as antimycobacterial agents. An efficient synthesis has been developed for 2-arylbenzimidazoles from o-phenylenediamines and aromatic aldehydes in molecular sieves-methanol system. The methodology is straightforward to get 2-arylbenzimidazoles (3a-3z) in excellent yields with high chemoselectivity over 2-aryl-1-benzylbenzimidazoles (4a-4z). All these benzimidazole analogues were evaluated against M. tuberculosis in BACTEC radiometric assay. The compounds 4y and 4z exhibited potential antitubercular activity against M. tuberculosis H (37)Rv, MIC at 16 mu M and 24 mu M respectively. The best compound of the series i.e. compound 4y was well tolerated by Swiss-albino mice in acute oral toxicity. Compound 4y possessing a diarylbenzimidazole core, can further be optimized for better activity.
