In this study, a series of 7-alkyloxy-4,5-dihydro-imidazo[1,2-a]quinoline derivatives was synthesized and tested for their antibacterial activity against various bacterial strains. Most of the compounds exhibited potential antibacterial activity against gram-negative and gram-positive bacteria. Compound 7p (7-heptyloxy-4,5-dihydro-imidazo[1,2-a]quinoline) was found to be the most potent inhibitor. The minimum inhibitory concentration (MIC) of compound 7p against Escherichia coli was 0.5 mu g/mL, better than that of reference agent ciprofloxacin and amoxicillin. Furthermore, compound 7p exhibited a modest activity against several gram-negative bacterial strains at a dose range of 2-64 mu g/mL. (C) 2013 Elsevier Masson SAS. All rights reserved.
