Technical Support

Filgotinib (GLPG0634) is a selective, orally available JAK1 inhibitor with anti-inflammatory and antiviral activities. Filgotinib can effectively inhibit the activities of JAK1, JAK2, JAK3 and TYK2 with IC₅₀ values of 10 nM, 28 nM, 810 nM and 116 nM, respectively. Filgotinib also inhibits HIV-1 driven gene transcription and reduces proliferation of HIV-1 infected cells. Filgotinib can be used in the study of rheumatoid arthritis and inflammatory bowel disease.

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

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.
