Anti-bacterial Agent

DrugBank - DB01165

• Drug Groups: approved
• Description: A synthetic fluoroquinolone (fluoroquinolones) antibacterial agent that inhibits the supercoiling activity of bacterial DNA gyrase, halting DNA replication. [PubChem]
• Indication: For the treatment of infections (respiratory tract, kidney, skin, soft tissue, UTI), urethral and cervical gonorrhoea.
• Pharmacology: Ofloxacin is a quinolone/fluoroquinolone antibiotic. Ofloxacin is bactericidal and its mode of action depends on blocking of bacterial DNA replication by binding itself to an enzyme called DNA gyrase, which allows the untwisting required to replicate one DNA double helix into two. Notably the drug has 100 times higher affinity for bacterial DNA gyrase than for mammalian. Ofloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria.
• Toxicity: LD₅₀=5450 mg/kg (orally in mice)
• Affected Organisms: Enteric bacteria and other eubacteria
• Biotransformation: Hepatic
• Absorption: Bioavailability of ofloxacin in the tablet formulation is approximately 98%
• Half Life: 9 hours
• Protein Binding: 32%
• Elimination: Elimination is mainly by renal excretion. Between 65% and 80% of an administered oral dose of ofloxacin is excreted unchanged via the kidneys within 48 hours of dosing. Four to eight percent of an ofloxacin dose is excreted in the feces. This indicates a small degree of biliary excretion of ofloxacin.

Research Area: Infection
Biological Activity:
Ofloxacin is a synthetic chemotherapeutic antibiotic of the fluoroquinolone drug class. Ofloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It functions by inhibiting DNA gyrase, a type II topoisomerase and topoisomerase IV, which is an enzyme necessary to separate replicated DNA, thereby inhibiting cell division. [1]

Other Notes
Nalidixic acid analog with broad-spectrum antibacterial activity.
Application
Ofloxacin is a synthetic fluoroquinolone with broad-spectrum antibacterial activity. It is a nalidixic acid analog. It is given to patients before undergoing retinal reattachment surgery1. It is used to study pneumococcal cell wall-degrading virulence factors2.
Biochem/physiol Actions
Ofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, which haults DNA replication and cell division. Ofloxacin has been shown to convert LytA from the inactive E-form to the active C-form2. It is a chiral molecule that inhibits pneumococcal cell wall-degrading virulence factors2.
