生物活性

Delafloxacin meglumine (ABT492 meglumine; RX-3341 meglumine; WQ-3034 meglumine) is a broad-spectrum fluoroquinolone antibiotic. Delafloxacin has a broad spectrum of activity that includes drug-resistant Staphylococcus aureus, Streptococcus pneumoniae, and Klebsiella pneumonia.

体内研究(In Vivo)

Delafloxacin (the total daily doses vary from 0.156 to 640 mg/kg/24 h, subcutaneous injection) is highly effective against S. aureus. Against all four strains are observed a decrease of 1.5 to 2.2 log₁₀ CFU in organism burden from untreated controls at even the lowest dose studied, and for two strains (MW2 and R2527) there is net bactericidal activity at the lowest dose. At the maximal doses studied, there is a >4-log₁₀ kill from initial burden for all S. aureus strains.
Delafloxacin (2.5, 10, 40, and 160 mg/kg; subcutaneous injection, 24 h) has moderate terminal elimination half-life (t_1/2=0.68 h, 0.79 h, 0.69 h and 1.0 h for 2.5 mg/kg, 10 mg/kg, 40 mg/kg, and 160 mg/kg, respectively).

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

Animal Model:	Mice with a neutropenic murine lung infection model (four S. aureus, four S. pneumoniae, and four K. pneumoniae strains)
Dosage:	The total daily doses vary from 0.156 to 640 mg/kg/24 h
Administration:	0.03 to 160 mg/kg are administered every 6 h (q6h) to infected mice by subcutaneous injection
Result:	Inhibited S. aureus strains ATCC 29213, ATCC 33591, MW2, R2527 with MICs of 0.008, 0.008, 0.004, and 0.004 mg/L, respectively. Inhibited S. pneumoniae strains ATCC 10813, ATCC 49619, 145, and 1329 with MICs of 0.03, 0.125, 0.016, and 0.016 mg/L, respectively. Inhibited K. pneumonia strains ATCC 43816, 4105, 4110, and 81-1260A with MICs of 0.06, 1, 0.5, and 0.06 mg/L, respectively.

Animal Model:	Neutropenic mice
Dosage:	2.5, 10, 40, and 160 mg/kg; 0.2 mL
Administration:	Subcutaneous injection; 24 h
Result:	The maximum drug concentrations (C_max) concentrations ranged from 2 to 71 mg/L. AUC_0-∞ values ranged from 2.8 to 152 mg?h/L and were linear across the 2.5- to 160-mg dosing range. The elimination half-life (t_1/2) ranged from 0.7 to 1 h.

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
