Description

GSK864 is an isocitrate dehydrogenase 1 (IDH1) mutant inhibitor; inhibits IDH1 mutants R132C, R132H, and R132G with IC50 values of 8.8, 15.2 and 16.6 nM.

IC50 & Target

IC50: 8.8 nM (IDH1 mutants R132C), 15.2 nM (IDH1 mutants R132H), 16.6 nM (IDH1 mutants R132G)[1]

In Vitro

GSK864 inhibits 2-HG production in R132C IDH1 mutant HT1080 fibrosarcoma cells with an EC50 of 320 nM by LCMS/MS analysis[1].

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

In Vivo

Following intraperitoneal (IP) administration in CD-1 mice, significant concentrations of GSK864 are maintained in peripheral blood samples of mice for up to 24 hours. Analysis of BM cells for expression of markers of early differentiation reveals slightly increased numbers of huCD45+ CD38+ cells in R132C or R132H IDH1 mutant engrafted mice treated with GSK864[1].

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 (4.48 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 (4.48 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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.

Animal Administration
[1]

Mice: Mice receive GSK864 (213 mg/kg, 10 mL/kg) via intraperitoneal (ip) administration. IP formulation is PG:DMSO:PEG400:H2O (16.7:3.3:40:40). Serial blood samples (~0.030 mL) are collected via the femoral artery catheter at 15, 30, 45, 60, 120, 180 min following administration[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.
