Title: Synthesis and antibacterial activity of novel 6-fluoro-1-[(1R,2S)-2-fluorocyclopropan-1-yl]-4-oxoquinoline-3-carboxylic acids bearing cyclopropane-fused 2-amino-8-azabicyclo[4.3.0]nonan-8-yl substituents at the C-7 position.

Abstract: A series of novel 6-fluoro-1-[(1R,2S)-2-fluorocyclopropan-1-yl]-4-oxoquinoline-3-carboxylic acids bearing cyclopropane-fused 2-amino-8-azabicyclo[4.3.0]nonan-8-yl substituents at the C-7 position were synthesized to obtain potent drugs for the treatment of Gram-positive infections. Some compounds exhibited excellent antibacterial activity, and potent inhibitory activity against bacterial DNA topoisomerase IV. In addition, some of the potent compounds showed reduced inhibitory activity against human DNA topoisomerase II compared with the corresponding noncyclopropane-fused compounds.
