SYNTHESIS OF NEW IMIDAZOLE DERIVATIVES AS EFFECTIVE ANTIMICROBIAL AGENTS
In the present work, some new imidazole derivatives (3i-xii) were synthesized as per design synthetic protocol scheme. The structures of newly prepared compounds were confirmed by modern analytical technique (IR, 1H-NMR, Mass spectral data) and elemental analysis, results found in full agreement with their assigned structures. All the
synthetic compounds were screened for their antimicrobial activity against bacterial strains viz. Escherichia coli (E. coli, MTCC 2961), Staphylococcus aureus (S. aureus, MTCC 3160), Bacillus subtilis (B. subtilis, MTCC 121), Klebsiella pneumoniae (K. pneumoniae, MTCC
3040) and Micrococcus luteus (M. luteus, MTCC 7527)) and fungal strains viz. Candida albicans (C. albicans, MTCC 227), Aspergillus niger (A. niger, MTCC 277) and Aspergillus flavus (A. flavus, MTCC 418); results showed good to remarkable activity. The MIC (minimum inhibitory concentration) values were determined by comparison to ciprofloxacin (anti-bacterial) and fluconazole (anti-fungal) as standard drug. Among them, compound 3iv and 3x exhibited notable antimicrobial activity. These compounds may be used as new template for the searching of potential antimicrobial agents.
