Levofloxacin 生物活性

靶点
  • Topo II

描述 Levofloxacin is a new fluoroquinolone antibiotic which is the active isomer of ofloxacin[3]. It is active against S. aureus, S. epidermidis, B. subtilis, E. coli, P. aeruginosa, and K. pneumoniae (MICs = 0.25, 0.25, 0.5, 0.03, 4, and 0.25 μg/ml, respectively)[4]. In stable chronic obstructive pulmonary disease, levofloxacin treatment (500mg/day) causes a short term reduction in bacterial load among patients[5].
