A series of fluoroquinolone antibacterials having the 7-position (10-position of pyridobenzoxazines) substituted with 2,7-diazaspiro[4.4]nonane (4b), 1,7-diazaspiro[4.4]nonane (5a), or 2,8-diazaspiro[5.5]undecane (6b) was prepared, and their biological activities were compared with piperazine and pyrrolidine substituted analogues. Most exhibited potent Gram-positive and Gram-negative activity, especially when side chain 4b was N-alkylated.
