| Description | Sparfloxacin (CI-978) is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase, thus preventing DNA replication and transcription. |
| In vitro | Orally administered Sparfloxacin produces favorable therapeutic outcomes in mice with systemic infections caused by Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, and Pseudomonas aeruginosa. |
| In vivo | Sparfloxacin targets DNA gyrase, inhibiting DNA synthesis. It exhibits potent, broad-spectrum antimicrobial activity, effective against Gram-positive bacteria such as Staphylococcus, Streptococcus, and Enterococcus species (MIC=0.1 to 0.78μg/ml), Gram-negative bacteria including Enterobacteriaceae and Pseudomonas species (MIC=0.0125 to 1.56μg/ml), glucose non-fermenters (MIC=0.025 to 0.78μg/ml), Legionella (MIC=0.0125 to 0.05μg/ml), and anaerobes (MIC=0.2 to 0.78μg/ml). |
