|Description||Filgotinib (GLPG0634) is a selective JAK1 inhibitor with IC50 of 10 nM, 28 nM, 810 nM, and 116 nM for JAK1, JAK2, JAK3, and TYK2, respectively. Phase 2.|
In cell lines, GLPG0634 inhibits IL-2- and IL-4-induced JAK1/JAK3/γc signaling and IFN-αB2-induced JAK1/TYK2 type II receptor signaling with IC50 ranged from 150 to 760 nM. GLPG0634 shows higher selectivity for JAK/STAT signaling involving JAK1 than JAK2 kinase in a cellular context. Besides, GLPG0634 also inhibits the differentiation of Th1, Th2, and Th17 cells. 
|In vivo||Following oral administration, the absolute bioavailability is moderate in rats (45%) and high in mice (∼100%). Filgotinib (30 mg/kg daily (Rats); 50 mg/kg twice daily (Mice)) dose-dependently reduces inflammation, cartilage, and bone degradation in the CIA model in rats and mice.  Filgotinib (GLPG0634) in DSS-treated mice demonstrates that inhibition of JAK1 is sufficient for achieving strong efficacy in pre-clinical mouse model, correlated to the inhibition of STAT3 phosphorylation in the inflamed colon. |
|In vitro||DMSO||85 mg/mL (199.76 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
4% DMSO+30% PEG 300+ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
