    体外実験

    Galunisertib (LY2157299) (0.1, 1, 10, and 100 μM) displays a slight dose-dependent potentiation of Bay 43-9006 in SK-Sora, HepG2, and Hep3B cell lines but not in JHH6, SK-HEP1, and HuH7 cell lines[2].

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

    体内実験

    Human xenografts Calu6 (non-small cell lung cancer) and MX1 (breast cancer) are implanted subcutaneously in nude mice. After oral administration of 75 mg/kg, Galunisertib (LY2157299) induces a 70% decrease in pSmad for both types of cell lines. The time at which pSmad recovered 80% of baseline is approximately 6 h after administration[3].

    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:  5% DMSO    40% PEG300    5% Tween-80    50% Saline

      Solubility: ≥ 5.75 mg/mL (15.56 mM); Clear solution

    • Protocol 2

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

      Solubility: ≥ 2.08 mg/mL (5.63 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

    Cell survival is determined using the MTT assay. The conversion of yellow water-soluble tetrazolium MTT into purple insoluble formazan is catalyzed by mitochondrial dehydrogenases and used to estimate the number of viable cells. In brief, cells are seeded in 96-well tissue culture plates at a density of 2×103 cells/well. After drug exposure, cells are incubated with 0.4 mg/mL MTT for 4 hours at 37°C. After incubation, the supernatant is discarded, insoluble formazan precipitates are dissolved in 0.1 mL of DMSO, and the absorbance is measured at 560 nm by use of a microplate reader. Wells with untreated cells or with drug-containing medium without cells are used as positive and negative controls respectively. For proliferation assay, MTT assay is done daily to determine the number of viable cells in untreated control andGalunisertib (LY2157299) (0.1, 1, 10, and 10 μM)-treated group[2].

    Mice[3]
    Charles River nude mice (weight 25 mg) are used. Galunisertib (LY2157299) is given orally as a single dose or in a multiple dosing design. The value of the dose levels given in a single dose manner is 10 (n=3), 30 (n=8), 50 (n=26), 75 (n=69), 100 (n=3), 150 (n=21) and 300 (n=3) mg/kg. Animals are sacrificed at the following times: 0.5, 1, 1.5, 2, 4, 8 and 16 h after administration, then the tumor is removed and blood is recovered. In the multiple dosing study, Galunisertib (LY2157299) is administered twice a day (bid) at the dose of 75 mg/kg every 12 h for 20 consecutive days to 31 mice. Animals are sacrificed at 2 h after the last administration at days 10, 15, 20 and 25, and the tumor is removed for pSmad determination and the blood is recovered for determination of drug levels in plasma.

    • 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.
