| | Clinafloxacin hydrochloride Usage And Synthesis |
| Chemical Properties | Pale Yellow Solid | | Uses | antibacterial | | Uses | A new fluoroquinolone antimicrobial agent as a potent intraphagocytic bactericidal agent for both gram-positive and gram-negative bacteria. | | Biological Activity | clinafloxacin is a broad-spectrum antibiotic of the quinolone carboxylic acid category that inhibits both dna gyrase and topoisomerase iv dually in streptococcus pneumonia. clinafloxacin, a fluoroquinolone, is currently in development for oral and intravenous therapy of serious infections.in selected volunteer subjects and patients, after the administration of oral and intravenous doses of racemic drug, the clinafloxacin showed a broad-spectrum antibiotic of the quinolone carboxylic acid category. the absorption of the clinafloxacin enantiomer was rapid after oral 400 mg dose and 400 mg intravenous dose of racemic drug [1]. clinafloxacin showed high activity against s. pneumoniae 7785 with the mic value of 0.125 μg/ml. clinafloxacin showed potent broad-spectrum in vitro activity against gram-positive, gram-negative, and anaerobic pathogens [2]. clinafloxacin has been identified as the most active fluoroquinolone against s. pneumoniae compared to grepafloxacin, levofloxacin, ofloxacin, sparfloxacin, and trovafloxacin and is currently being evaluated as an antipneumococcal agent [3]. | | references | [1]. humphrey g h, shapiro m a, randinitis e j, et al. pharmacokinetics of clinafloxacin enantiomers in humans[j]. the journal of clinical pharmacology, 1999, 39(11): 1143-1150.
