structure-activity relationship studies indicated that 1-[(1R,2S)-2-fluorocyclopropyl] and 7-[(7S)-amino-5-azaspiro[2.4]heptan-5-yl] derivatives are more potent against Gram-positive and Gram-negative bacteria than the other stereoisomers and 7-[(7S)-7-amino-5-azaspiro[2.4]-heptan-5-yl]-8-chloro-1-[(1R ,2S)-2- fluorocyclopropyl]quinolone (33) is the most potent of all stereoisomers.
