Gatifloxacin molecular structure

Gatifloxacin

Also known as: Tequin, Zymar, Zymaxid, Gatiquin, Gaty

CAS Number: 112811-59-3

Fluoroquinolone Antibacterial

Pharmacopeia Standards

USPIPJPCP

Mechanism of Action

Gatifloxacin inhibits both DNA gyrase and topoisomerase IV with balanced affinity, which raises the barrier to single-step target mutation. The 8-methoxy substituent improves Gram-positive and anaerobic coverage relative to earlier quinolones. Bactericidal activity is concentration dependent.
