Description
Levofloxacin is the S-(−) isomer of ofloxacin. Levofloxacin is a fluoroquinolone antibiotic that inhibits DNA gyrase and topoisomerase IV; it exhibits antibacterial efficacy against gram negative and gram positive bacteria. Levofloxacin also displays anticancer activity, as when complexed with gold(III), it binds DNA and inhibits cellular proliferation in several cancer cell lines.
