Abstract

CP-99,219 is a trifluoronaphthyridone with significant antibacterial activity that includes the family Enterobacteriaceae (MICs for 90% of the strains tested [MIC90s], < or = 0.015 to 0.5 micrograms/ml), Moraxella catarrhalis, Haemophilus influenzae, and gonococci (MICs, < or = 0.015 micrograms/ml). Legionella spp. were also CP-99,219 susceptible, with MICs of 0.008 to 0.12 micrograms/ml. CP-99,219 demonstrated activity greater than that of ciprofloxacin, ofloxacin, or enoxacin against Pseudomonas aeruginosa (MIC90, 1 microgram/ml), Xanthomonas maltophilia (MIC90, 2 micrograms/ml), Staphylococcus haemolyticus (MIC90, 0.5 micrograms/ml), Enterococcus faecalis (MIC90, 1 microgram/ml), and pneumococci (MIC90, 0.12 micrograms/ml). Numerous ciprofloxacin-resistant isolates were susceptible to CP-99,219, a new compound showing potential value for further in vivo trials.

摘要

CP - 99,219是一种具有显著抗菌活性的三氟萘啶酮,其抗菌谱包括肠杆菌科(90%受试菌株的最低抑菌浓度[MIC90],≤0.015至0.5微克/毫升)、卡他莫拉菌、流感嗜血杆菌和淋球菌(MIC,≤0.015微克/毫升)。嗜肺军团菌对CP - 99,219也敏感,MIC为0.008至0.12微克/毫升。CP - 99,219对铜绿假单胞菌(MIC90,1微克/毫升)、嗜麦芽窄食单胞菌(MIC90,2微克/毫升)、溶血葡萄球菌(MIC90,0.5微克/毫升)、粪肠球菌(MIC90,1微克/毫升)和肺炎球菌(MIC90,0.12微克/毫升)的活性高于环丙沙星、氧氟沙星或依诺沙星。许多耐环丙沙星的分离株对CP - 99,219敏感,这一新型化合物显示出进一步进行体内试验的潜在价值。
