Merafloxacin (CI 934) is a quinolone antibacterial. It is an inhibitor of Type II DNA topoisomerase. It demonstrated excellent activity against gram-positive organisms, including Corynebacterium sp. In addition, although the activity of merafloxacin against gram-negative bacilli was less than that reported for similar agents, it was comparable to that of aminoglycosidic aminocyclitol antibiotics. Merafloxacin development has been discontinued.
