Biochem/physiol Actions

Levonadifloxacin is a potent benzoquinolizine fluoroquinolone antibiotic that is affective against Gram-positive and Gram-negative bacteria, including methicillin- and quinolone-resistant Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, and Moraxella catarrhalis and atypical pathogens. It appears that Levonadifloxacin targets staphylococcal DNA gyrase, unlike other quinolones, which primarily inhibit DNA topoisomerase IV.
