In order to find new antibacterial agent with wide spectra and high activities, 8 new (2-chloroquinolin-3-yl)meth- yleneamino guanidine derivatives were synthesized based on combination principles, whose structures were then identified by spectral methods. All of the compounds provided exhibited good inhibitory activities against the strains chosen, except Salmonella typhimurium 2421 and Pseudomonas aeruginosa 2742, of which MICs were mostly in the range of 2.0~16 μg/mL. The compound 4h showed the best broad-spectrum antibacterial activities, whose MIC value was 2.0 μg/mL against six strains. The inhibitory activities of 4h, against Staphylococcus aureus KCTC 503 and two drug-resistance bacterias (Methicillin-resistant Staphylococcus aureus CCARM 3167 and Quinolone-resistant Staphylococcus aureus CCARM 3505), were superior or equal to positive controls gatifloxacin, moxifloxacin, norfloxacin and oxacillin.

Key words: alkylene aminoguanidine, 2-chloroquinoline, antibacterial activity, drug-resistance bacteria
