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[1].
Delafloxacin (2.5, 10, 40, and 160 mg/kg; subcutaneous injection, 24 h) has moderate terminal elimination half-life (t1/2=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)[1].

MedChemExpress (MCE) 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)[1]
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[1]
Dosage: 2.5, 10, 40, and 160 mg/kg; 0.2 mL
Administration: Subcutaneous injection; 24 h
Result: The maximum drug concentrations (Cmax) concentrations ranged from 2 to 71 mg/L. AUC0-∞ 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 (t1/2) ranged from 0.7 to 1 h.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (3.93 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (3.93 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

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.
