| Description | Gatifloxacin (CG5501) is an antibiotic of the fourth-generation fluoroquinolone family, that like other members of that family, inhibits the bacterial enzymes DNA gyrase and topoisomerase IV. |
| Targets&IC50 | Topo II:36.7 μM (IC50) |
| In vitro | Gatifloxacin increases serum adrenaline levels in both normal and diabetic rats, and concurrently reduces serum glucose concentrations in these subjects. |
| In vivo | Gatifloxacin exhibits potent inhibitory activity against bacterial type II topoisomerases, with half-maximal inhibitory concentrations (IC50) of 13.8 mg/mL and 0.109 mg/mL for Staphylococcus aureus topoisomerase and Escherichia coli DNA gyrase, respectively. Its inhibitory effect on HeLa cell topoisomerase II is minimal, with an IC50 of 265 mg/mL. Gatifloxacin inhibits Mycobacterium tuberculosis ATCC 35801 with a minimum inhibitory concentration (MIC) of 0.125 μg/mL. When used in combination with ciprofloxacin, gatifloxacin demonstrates a synergistic effect on 19% of 31 strains of Pseudomonas aeruginosa. However, gatifloxacin's activity is two-fold lower than that of ciprofloxacin and two-fold less potent than ofloxacin against Enterobacteriaceae. Gatifloxacin shows strong antimicrobial activity against Haemophilus influenzae, Legionella, and Helicobacter pylori (MIC90s, 0.03-0.06 mg/L), and at least an eight-fold greater efficacy against Chlamydiaceae and Mycoplasmataceae (gatifloxacin MIC90s, 0.13 mg/L). |
