[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is a quinolone that is quinolin-4(1H)-one bearing cyclopropyl, carboxylic acid, fluoro and piperazin-1-yl substituents at positions 1, 3, 6 and 7, respectively. It has a role as an antiinfective agent, a topoisomerase IV inhibitor, an antibacterial drug, an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor, a DNA synthesis inhibitor, an antimicrobial agent, an environmental contaminant and a xenobiotic. It is a quinolone antibiotic, a fluoroquinolone antibiotic, a member of cyclopropanes, a N-arylpiperazine, a quinolone, an aminoquinoline and a quinolinemonocarboxylic acid. It is a conjugate base of a ciprofloxacin(1+). It is a tautomer of a ciprofloxacin zwitterion."}, {"from": "gpt", "value": "[C][C][C][Ring1][Ring1][N][C][=C][Branch2][Ring1][=N][C][=Branch1][C][=O][C][=C][C][=Branch2][Ring1][C][=C][Branch1][#Branch1][C][=C][Ring1][=Branch1][Ring1][O][N][C][C][N][C][C][Ring1][=Branch1][F][C][=Branch1][C][=O][O]"}]
