Delafloxacin is a potent agent and broad-spectrum anionic fluoroquinolone against Streptococcus pneumoniae and diverse group of pathogens.

Delafloxacin is a fluoroquinolone antibiotic active against both Gram-negative and Gram-positive bacteria such as MRSA. Delafloxacin targets both DNA gyrase and topoisomerase IV, inhibiting DNA synthesis. Unlike most fluoroquinolones, delafloxacin is weakly acidic, which increases its potency in an acidic environments such as those existing in inflammatory cells and in skin and soft tissue infections. Delafloxacin shows good activity against most fluoroquinolone-resistant strains.
