Synthesis, antibacterial activities, binding mode analysis and predictive ADME studies of novel 1-(aryl)-2-(1H-imidazol-1-yl)methanones

Abstract

Introduction: In the present study a novel series of twelve 1-(aryl)-2-(1H-imidazol-1-yl)methanones 3(a-l) were synthesized and characterised by physicochemical and spectral analysis,viz. elemental analysis, IR spectroscopy, NMR spectroscopy. The antibacterial property of the compounds were examined, in order to develop new broad spectrum antibiotics. Methods: The compounds 3(a-l) were synthesised by reacting the corresponding 2-(aryl)-1H-imidazoles 2 with substituted benzoyl chlorides. Binding mode analysis of the most active compound was carried out. Predictive ADME studies were carried out for all the compounds. Results and Discussions: Among the synthesized compounds, (2-(3-nitrophenyl) (2,4-dichlorophenyl) -1Himidazol-1-yl)methanone 3i exhibited highest antibacterial activity. Binding mode analysis of the highest active compound was carried out in the active site of glucosamine-6-phosphate synthase (2VF5).
