Designed, synthesized a sequence of novel benzimidazol-1-yl-1-phenylpropanone hybrids and assessed for in vitro antimicrobial potential counter to several bacterial strains. Computational Methodology was carried out for designing of the target molecules and structures were confirmed by spectroscopic analysis. Amid the 12 integrated derivatives, (3-(2-((3-fluorobenzylidene)amino)-1H-benzo[d]imidazol-1-yl)-1-phenylpropan-1-one ( 6g ) and 3-(2-((4-fluorobenzylidene)amino)-1H-benzo[d]imidazol-1-yl)-1-phenylpropan-1-one ( 6k ) were found to acquire excellent antibacterial activity against all bacterial strains (Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Staphylococcus aureus), whereas derivative 3-(2-((2-fluorobenzylidene)amino)-1H-benzo[d]imidazol-1-yl)-1-phenylpropan-1-one ( 6c ), was potent against Escherichia coli, Bacillus subtilis, Staphylococcus aureus and displayed moderate action against P. aeruginosa. Derivatives with NO2 substituent at 3rd and 4th position, 3-(2-((3-nitroobenzylidene)amino)-1H-benzo[d]imidazol-1-yl)-1-phenylpropan-1-one ( 6h ) and 3-(2-((4-nitroobenzylidene)amino)-1H-benzo[d]imidazol-1-yl)-1-phenylpropan-1-one ( 6 l ) respectively declared good to moderate results against all bacterial strains. Further, 3-(2-((3-chlorobenzylidene)amino)-1H-benzo[d]imidazol-1-yl)-1-phenylpropan-1-one ( 6f ) and 3-(2-((4-chlorobenzylidene)amino)-1H-benzo[d]imidazol-1-yl)-1-phenylpropan-1-one ( 6j ) were found to be more competent against both fungal strains (C. albicans, A. niger). Serial two-fold dilution method was used for the entire study and standard drugs utilized were ciprofloxacin and clotrimazole. MIC values (μg/ml) of novel synthesized analogs were reported in comparison to standard drugs for antibacterial and antifungal actions. Molecular docking studies showed that designed molecules dynamically bound with effective area of the receptor (DNA gyrase B, Clotrimazole complex of cytochrome P 45046A1) and in vitro results were in accord with in silico studies. 相似文献
