  Synthesis, antimicrobial and cytotoxic activity of 2-azetidinone derivatives of pyridyl benzimidazoles

  摘要：

  In the present study, a series of novel 6-(1H-benzo[d]imidazol-2-yl)-2-(3-chloro-2-oxo-4-phenylazetidin-1-yl)-4-(aryl)nicotinonitriles 6a-o were efficiently synthesized and evaluated for their in vitro antibacterial activity against Gram-positive (Staphylococcus aureus and Streptococcus pyogenes), Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria and fungal (Candida albicans, Aspergillus niger and Aspergillus clavatus) strains. The results of antimicrobial study revealed that compounds 6b, 6c, 6d, 6h and 6i exhibited substantial antibacterial activity while compounds 6c and 6h emerged as the most potent antifungal agents compared to the standard drugs chloramphenicol and ketoconazole, respectively. From the standpoint of SAR studies, it was observed that the presence of electron-withdrawing groups remarkably enhances the antibacterial activity of newly synthesized compounds. Further, the results of preliminary MTT cytotoxicity studies on HeLa cells suggested that potent antimicrobial activity of 6b, 6c, 6d, 6h and 6i is accompanied by low level of cytotoxic concentrations. All the newly synthesized analogues were characterized by IR, H-1 NMR, C-13 NMR and mass spectral data.

  A new series of compounds N-(4-(2-(3-(1H-benzo[d]imidazol-2-yl)-5-(aryl)-4,5-dihydro-1H-pyrazol-1-yl)-2-oxoethoxy)phenyl)acetamides (5a–u) were synthesized and structures of these compounds were elucidated by spectral (IR, 1H NMR, 13C NMR, and mass spectra) analysis. Antimicrobial activity was measured against Escherichia coli (MTCC 443), Pseudomonas aeruginosa (MTCC 1688), Staphylococcus aureus (MTCC

  一系列新的化合物N-（4-（2-（3-（1 H-苯并[ d ]咪唑-2-基] -5-（芳基）-4,5-二氢-1 H-吡唑-1-合成了yl）-2-氧代乙氧基）苯基）乙酰胺（5a - u），并通过光谱分析（IR，1 H NMR，13 C NMR和质谱）阐明了这些化合物的结构。测量了对大肠杆菌（MTCC 443），铜绿假单胞菌（MTCC 1688），金黄色葡萄球菌（MTCC 96），化脓性链球菌（MTCC 442），白色念珠菌（MTCC 227），黑曲霉（Aspergillus niger）的抗菌活性（MTCC 282）和曲霉曲霉（MTCC 1323）的连续肉汤稀释法。抗菌活性的评估表明，与标准药物相比，化合物5f，5i，5q和5t是最有效的抗菌剂，而化合物5e，5g，5h，5j，5p，5r和5u是最有效的抗菌剂，因此有望成为新的铅分子。
