Gemifloxacin

Class: Fluoroquinolone

Spectrum of activity:	Gram-positive  &  Gram-negative
Details of activity:	Binds to type II topoisomerases, gyrase and topoisomerase IV and thus, inhibits DNA cleavage and ligation reactions. It kills bacterial cells by increasing the concentration of enzyme–DNA cleavage complexes, thereby inhibiting cell replication.
Description:	Synthetic quinoline derivative.
Year first mentioned:	1997
Development status:	Approved, off patent, withdrawn in most countries
