In vitro antibacterial activity of a new quinolone, NM394.
NM394 is a new 6-fluoroquinolone antibacterial agent with a tricyclic structure which has a bridge that connects the N-1 and C-2 positions of the quinolone. The antibacterial activity of NM394 against clinical isolates of staphylococci, streptococci, enterococci, members of the family Enterobacteriaceae, and Pseudomonas aeruginosa was equal to or one-half that of ciprofloxacin. NM394 was as act...
متن کاملUptake and intracellular activity of NM394, a new quinolone, in human polymorphonuclear leukocytes.
The uptake of NM394, a new quinolone, by and its subsequent elution from human polymorphonuclear leukocytes were studied and compared with those of ofloxacin and ciprofloxacin. The kinetics of the uptake of NM394 was similar to that of ciprofloxacin. The maximum intracellular-to-extracellular concentration ratio was 12.3, compared with 8.6 for ciprofloxacin and 4.9 for ofloxacin at the extracel...
متن کاملComparative in vitro antibacterial activity of sparfloxacin (AT-4140; RP 64206), a new quinolone.
The in vitro activity of sparfloxacin (AT-4140; RP 64206), a new fluoroquinolone, was compared with those of 10 other agents against 1,222 clinical isolates. Sparfloxacin and ciprofloxacin were the most active quinolones against members of the family Enterobacteriaceae and nonfermenting gram-negative bacilli; sparfloxacin had superior activity against gram-positive cocci in comparison with the ...
متن کاملIn vitro activity of HSR-903, a new quinolone.
The in vitro activity of the new fluoroquinolone HSR-903 was compared with those of ciprofloxacin, lomefloxacin, sparfloxacin, and levofloxacin. HSR-903 inhibited 90% of methicillin-susceptible and -resistant Staphylococcus aureus (MRSA) clinical isolates at 0.78 and 1.56 microg/ml, respectively, and its activity against MRSA was 16-fold higher than those of sparfloxacin and levofloxacin and 64...
متن کاملComparative in vitro activity of a new quinolone, AM-1091.
The in vitro activity of a new quinolone, AM-1091 [7-(3-amino-1-pyrrolidinyl)-8-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro- 4-oxo- 3-quinoline carboxylic acid hydrochloride], was compared with those of ciprofloxacin, ofloxacin, beta-lactams, and gentamicin. AM-1091 inhibited 90% of the isolates of the family Enterobacteriaceae at less than or equal to 0.12 micrograms/ml. For many species AM-1091...
