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 (8.51 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 (8.51 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.

Cell Assay
[1]

HepG2 (HB-8065) cells are cultured with fresh medium (essential minimum Eagle medium, EMEM, supplemented with 5% fetal calf serum and 2 mM l-glutamine) the day before subculturing the plates. On the day of the assay, cells (10 000 cells/well) are seeded in a black 96-well collagen coated microplate with clear bottom, except in column 11, which is dispensed only 100 mL of culture medium. Stock solution from GSK656 is prepared in 100% DMSO. Ten serial 1:2 dilutions are prepared of GSK656, and finally, a 1:200 dilution is made, in medium, to achieve a final concentration of 0.5% of DMSO. Resazurin tablets are dissolved in phosphate buffer saline at a concentration of 0.0042%. After 24 h of incubation of the cells (37°C, 5% CO2, 95% relative humidity), a volume of 150 μL of culture medium containing the appropriate test concentrations of GSK656 dilutions is added to cells in two replicates. Only 150 μL of 0.5% DMSO is added as blank control. Then, cells are exposed to GSK656 for 48 h. After that, medium is removed and resazurin solution is added to each well and incubated for further 1.5 h. Fluorescence is measured at an excitation wavelength of 515 nm and an emission wavelength of 590 nm in a Microplate reader 1420 Multilabel HTS counter, Victor 2[1].

Animal Administration
[1]

Mice[1]
Specific pathogen-free, 8- to 10-week-old female C57BL/6 mice are allowed to acclimate for 1 week. In brief, mice are intratracheally infected with 100 000 CFU/mouse of M. tuberculosis H37Rv. GSK656 is administered for 8 consecutive days starting 1 day after infection. For the chronic assay, mice are intratracheally infected with 100 CFU/mouse and GSK656 administered daily (7 days a week) for 8 consecutive weeks starting 6 weeks after infection. Lungs are harvested 24 h after the last administration, and all lung lobes are aseptically removed, homogenized, and frozen. Homogenates are plated onto 10% OADC-Middlebrook 7H11 medium and incubated for 21 days at 37°C. GSK656 is administered by intravenous route at 5 mg/kg single dose in saline and by oral gavage at 30 mg/kg single dose in 1% methylcellulose (1% MC). For iv route aliquots of 15 μL of blood are taken from the lateral tail vein by puncture from each mouse (n = 3) at 5, 15, and 30 min and 1, 2, 4, 8, and 24 h postdose; for oral route aliquots of 15 μL of blood are taken from the lateral tail vein by puncture from each mouse (n = 3) at 15, 30, and 45 min and 1, 2, 4, 8, and 24 h postdose[1].

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.
