Abstract
Bacterial DNA gyrase and topoisomerase IV inhibition has emerged as a promising strategy for the cure of infections caused by antibiotic-resistant bacteria. Small molecule antibacterials inhibiting bacterial topoisomerases have been previously exploited by the successful fluoroquinolone class. The Novel Bacterial Topoisomerase Inhibitors (NBTIs) bind to a different site to that of the fluoroquinolones with novel mechanism of action to evade the existing target-mediated bacterial resistance associated with fluoroquinolones. This review comprehensively summarizes various efforts with respect to structural modifications of inhibitors and their impact on their general physicochemical and biological properties.
