چکیده

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 isolates were 3.13 and 62.5 micrograms/ml, respectively.

In vitro activities of ofloxacin and four other new quinoline-carboxylic acids against Chlamydia trachomatis.

The in vitro activities of five new quinoline-carboxylic acids against 2 reference strains and 45 clinical isolates of Chlamydia trachomatis of genital origin were compared with the activities of minocycline and doxycycline. Ofloxacin was the third most active agent (after the two tetracyclines), followed by ciprofloxacin, NY-198, and AM-833.

In vitro activity of ceftriaxone, cefetamet (Ro 15-8074), ceftetrame (Ro 19-5247; T-2588), and fleroxacin (Ro 23-6240; AM-833) versus Neisseria gonorrhoeae and Haemophilus ducreyi.

We examined 300 strains of Neisseria gonorrhoeae and 100 strains of Haemophilus ducreyi to determine their in vitro susceptibility to two new cephalosporins, cefetamet (Ro 15-8074) and ceftetrame (Ro 19-5247; T-2588), and a new fluroquinolone, fleroxacin (Ro 23-6240; AM-833). Their activity was compared with that of ceftriaxone, penicillin, spectinomycin, tetracycline, and erythromycin. Cefetam...

Antimicrobial activity of Ro 23-9424, a novel ester-linked codrug of fleroxacin and desacetylcefotaxime.

Ro 23-9424 is a novel ester-linked codrug of fleroxacin (Ro 23-6240; AM-833) and the cefotaxime metabolite desacetylcefotaxime. Its potency was determined against over 1,000 organisms and found to be intermediate between those of the two components. More than 99% of members of the family Enterobacteriaceae were inhibited by greater than or equal micrograms of Ro 23-9424 per ml; its MIC for 50% ...
