The in vitro activities of three newly developed quinolone drugs (T-3262, NY-198, and fleroxacin [AM-833; RO 23-6240]) against 10 strains of clinically isolated Chlamydia trachomatis were assessed and compared with those of other quinolones and minocycline. T-3262 (MIC for 90% of isolates tested, 0.1 microgram/ml) was the most active of the quinolones. The NY-198 and fleroxacin MICs for 90% of ...
Resistance to beta-lactams and fluoroquinolones has been increasing in the treatment of urinary tract infections (UTIs), worldwide. Recent studies in Europe and the United States have demonstrated that steady increase in the rate of uropathogen’s resistance to commonly prescribed antibiotics is associated with plasmid-mediated resistance genes existence. According to the published data, acquirе...
Moxifloxacin is an 8-methoxyquinolone compound with activity against a wide range of bacteria. We tested its activity in comparison with four other quinolones and isoniazid against clinical isolates of mycobacteria. It proved to be the most active of the quinolones tested against Mycobacterium tuberculosis (MIC90 0.25 mg/L), Mycobacterium avium-intracellulare (MIC90 1.0 mg/L), Mycobacterium kan...
This review outlines some of pharmacokinetic parameters factors of fluoroquinolones antimicrobial agents. The oral absorption is not altered in human patients with disease. Plasma protein binding of the quinolones varies but newer quinolones less bound to plasma proteins. The serum concentration peak is reached rapidly. Most of the fluoroquinolone primary metabolites are active against bacteria...
The relationship between the chemical structure and epileptogenic activity of quinolones was investigated. When the quinolones were administered intravenously to mice concomitantly with oral biphenylacetic acid, a major metabolite of the nonsteroidal antiinflammatory drug fenbufen, enoxacin, norfloxacin, ciprofloxacin, and pipemidic acid, which have an unsubstituted piperazine moiety at the 7 p...
BACKGROUND Quinolones are potent broad-spectrum bactericidal agents increasingly employed also in resource-limited countries. Resistance to quinolones is an increasing problem, known to be strongly associated with quinolone exposure. We report on the emergence of quinolone resistance in a very remote community in the Amazon forest, where quinolones have never been used and quinolone resistance ...
In vitro activity of ozenoxacin, a novel nonfluorinated topical (L. D. Saravolatz and J. Leggett, Clin. Infect. Dis. 37:1210-1215, 2003) quinolone, was compared with the activities of other quinolones against well-characterized quinolone-susceptible and quinolone-resistant Gram-positive bacteria. Ozenoxacin was 3-fold to 321-fold more active than other quinolones. Ozenoxacin could represent a f...
The 1,3-dipolar cycloaddition of 3-nitro-2(1H)-quinolones with ester-stabilized azomethine ylides derived from sarcosine ester and various aromatic aldehydes has been investigated. structure stereochemistry cycloadducts were studied in detail by X-ray NMR spectroscopy methods.
