Beschreibung

Nemonoxacin (TG-873870) is an orally active and potent broad-spectrum antibiotic. Nemonoxacin shows good inhibitory activity against different species of staphylococci, streptococci, and enterococci, Neisseria gonorrhoeae, and Haemophilus influenza. Nemonoxacin can be used in the study of bacterial infections and community-acquired pneumonia[1][2][3].

IC50 & Target

Bacterial[1][2][3].

In Vitro

Nemonoxacin (0-5.51 µM; 24 h) shows good antibacterial activity in vitro[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: MSSA, MRSA
Concentration: 0-5.51 µM (0-2048 µg/mL)
Incubation Time: 24 h
Result: Inhibited MSSA and MRSA with MIC90 values of 0.12 and 4 µg/mL.
In Vivo

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
