Abstract

A novel series of ketolides with 11, 12-sulfur contained aryl alkyl side chains were synthesized and evaluated for their antibacterial activity. These ketolides exhibited potent activity against key macrolide sensitive and resistant respiratory pathogens. The newly synthesized 9a, 9e, 9k and 9n showed a similar antimicrobial spectrum and comparable activity to telithromycin, the commercial ketolide antibacterial.
