A series of novel polyhalogenated 2-phenylbenzimidazoles have been synthesized and evaluated for in vitro antistaphylococcal activity against drug-resistant bacterial strains (methicillin-resistant Staphylococcus aureus, and vancomycin-resistant Enterococcus faecium. Certain compounds inhibit bacterial growth perfectly. 11 was active than vancomycin (0.78 mu g/mL) with the lowest MIC values with 0.19 mu g/mL against methicillin-resistant Staphylococcus aureus, 8 and 35 exhibited best inhibitory activity against vancomycin-resistant Enterococcus faecium (1.56 mu g/mL). The mechanism of action for this class of compounds appears to be different than clinically used antibiotics. These polyhalogenated benzimidazoles have potential for further investigation as a new class of potent anti-methicillin-resistant Staphylococcus aureus and anti-vancomycin-resistant Enterococcus faecium agents.
