title: Activity of AT-2266 compared with those of norfloxacin, pipemidic acid, nalidixic acid, and gentamicin against various experimental infections in mice.
abstract: AT-2266 (1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-1, 8-naphthyridine-3-carboxylic acid) showed marked activity in vivo when administered orally to mice bearing systemic, pulmonary, dermal, or urinary tract infections due to variety of organisms. The activity of AT-2266 was uniformly higher than those of norfloxacin, pipemidic acid, and nalidixic acid against all of the infections. The activity of AT-2266 administered orally was almost comparable to that of gentamicin administered subcutaneously against urinary tract infections due to gram-negative organisms but was generally lower against other infections. AT-2266 exhibited significant activity against infections due to gentamicin-resistant and nalidixic acid-resistant organisms.
