Nemonoxacin (p.o.; 15 min and 6 h after infection) shows potent and broad-spectrum in vivo activity against both Gram-positive (S. aureus, S. capitis, S. pneumonia and E. faecalis) and Gram-negative (E. coli) isolates[2]. Nemonoxacin (p.o.; 6, 12 and 24 h after infection) shows potent activities towards (2.5, 5, 10, 20 mg/kg) S. pneumonia 0613 (PRSP) and (10, 20, 40, 80 mg/kg) K. pneumonia 0607 infections in mouse pulmonary infection model[2]. Animal Model: CD-1 ICR mice (18-22 g; mouse systemic infection model)[2]. Dosage: 1.6-4.0 mg/kg (S. aureus and S. capitis infections), 2.4-10.0 mg/kg (S. pneumonia infections), 5.0-22.6 mg/kg (E. faecalis infections), 1.6-10.0 mg/kg (E. coli infections) Administration: Oral administration; 15 min and 6 h after infection Result: Showed the ED50s of 2.08, 2.59 and 2.52 mg/kg to against S. aureus ATCC 29213 (MSSA), S. aureus 0705 (MRSA) and S. capitis 0687 (levofloxacin-resistant MRSC), respectively. Animal Model: CD-1 ICR mice (18-22 g; mouse pulmonary infection model)[2]. Dosage: 2.5, 5, 10, 20 mg/kg (S. pneumonia 0613 (PRSP)); 10, 20, 40, 80 mg/kg (K. pneumonia 0607) Administration: Oral administration; 6, 12 and 24 h after infection Result: Significantly decreased colony counts in vivo.
