Description

Filgotinib (GLPG0634) is a selective and orally active JAK1 inhibitor with IC50 of 10 nM, 28 nM, 810 nM, and 116 nM for JAK1, JAK2, JAK3, and TYK2, respectively.

IC50 & Target[1]

JAK1

10 nM (IC50)

JAK2

28 nM (IC50)

Tyk2

116 nM (IC50)

JAK3

810 nM (IC50)

In Vitro

Filgotinib (GLPG0634) dose-dependently inhibits the differentiation of Th2 cells mediated by IL-4, a cytokine that signals through JAK1 and JAK3. Filgotinib also inhibits Th1 differentiation with similar potencies of 1 μM or lower[1]. Filgotinib (GLPG0634)?does not inhibit JAK2 homodimer-mediated signaling induced by EPO or PRL (IC50 > 10 μM)[2].

In Vivo

Filgotinib (GLPG0634; 3, 10, 30 mg/kg, p.o.) dose-dependently prevents disease progression in the therapeutic rat CIA model. Filgotinib (50 mg/kg, o.p.) protects bone and cartilage from degradation, effectively reduces infiltration of T cells (CD3+ cells) and macrophages (F4/80+ cells) in the paw, and decreases the serum levels of all cytokines and chemokines measured, including IL-6, IP-10, XCL1, and MCP-1[1]. Filgotinib (GLPG0634; 0.1 and 0.3 mg/kg) shows efficacy in the rat CIA model[2].

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 (5.88 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 (5.88 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.

Animal Administration
[1]

Filgotinib is orally dosed as a single esophageal gavage at 5 mg/kg (dosing volume of 5 mL/kg) and i.v. dosed as a bolus via the caudal vein at 1 mg/kg (dosing volume of 5 mL/kg). In the rat study, each group consists of three rats and blood samples are collected via the jugular vein. In the mouse study, each group consists of 21 mice (n=3/time point) and blood samples are collected by intracardiac puncture under isoflurane anesthesia. Lithium heparin is used as anticoagulant and blood is taken at 0.05, 0.25, 0.5, 1, 3, 5, and 8 h (i.v. route) and 0.25, 0.5, 1, 3, 5, 8, and 24 h (by mouth).

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.
