Synthesis and bacterial DNA gyrase inhibitory properties of a spirocyclopropylquinolone derivative

Journal of Medicinal Chemistry

Abstract

A novel conformationally restricted 1-cyclopropylquinolone (1) that incorporates structural features of both ofloxacin and ciprofloxacin has been prepared. Compound 1 was found to be a DNA gyrase inhibitor having potency similar to ofloxacin but less than ciprofloxacin. The cellular inhibitory and in vivo antibacterial potencies of 1 were found to be less than those of the two reference agents.
