有することを見出した。Nalidixic acid, pyromidic acid, and pipemidic acid are widely used clinically as highly safe synthetic antibacterial agents effective against Gram-negative bacterial infections. However, these drugs have very weak antibacterial activity against Gram-negative bacteria or Pseudomonas aeruginosa, which is one of the causative agents of refractory infections and for which there are few effective drugs. The present inventors previously discovered that a compound having a fluorine atom at the 6-position and a piperazine or substituted piperazine at the 7-position of 1-(2-fluoroethyl)-1,4-dihydro-4-oxoquinoline-3-carboxylic acid reported that it has strong antibacterial activity against Gram-negative bacteria and Gram-negative bacteria including Pseudomonas aeruginosa [98th Annual Meeting of the Pharmaceutical Society of Japan (1932)]
(April 2003, Okayama), Lecture Abstracts, P, 233, JP-A-55-47658] The present inventors then further investigated this related compound, and found that fluorine atoms at the 6th and 8th positions, and 7th position A 6,7°8-tri-substituted product simultaneously having a halogen atom or a piperazino derivative at the 6,7- or 7.8-
It was found that it has stronger antibacterial activity against Gram-negative bacteria than di-1 conversion.
