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

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
