How Besigen works

Besigen is a bactericidal fluroquinolone-type antibiotic that inhibits bacterial enzymes, DNA gyrase and topoisomerase IV. By inhibiting DNA gyrase, DNA replication, transcription, and repair is impaired. By inhibiting topoisomerase IV, decatenation during cell devision is impaired. Inhibiting these two targets also slows down development of resistance.
