生物活性

Levonadifloxacin ((S)-(-)-Nadifloxacin; WCK 771) is a broad-spectrum anti-staphylococcal agent. Levonadifloxacin shows antibacterial activity against Methicillin (HY-121544)-susceptible Staphylococcus aureus (MSSA) and Methicillin-resistant S. aureus (MRSA) strains, with a reduction of which phagocytized in THP-1 monocytes[1].

體外研究
(In Vitro)

Levonadifloxacin (32 μg/mL; 24 h) achieves a 90-99%?intracellular reduction of MSSA and MRSA strains phagocytized in THP-1 monocytes with MICs of 0.03 μg/mL and 15.0 ng/mL[1].

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

體內(nèi)研究
(In Vivo)

Levonadifloxacin (12.5-400 mg/kg; s.c.; single dose) shows efficacy in vivo against Staphylococcus aureus in a Neutropenic Murine Lung Infection Model[2].

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

Animal Model: Male/Female Swiss Albino mice (25-28 g) for plasma pharmacokinetic analyses[2]
Dosage: 12.5, 25, 50, 100, 200, 300 and 400 mg/kg

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.
