Purity: ≥98%
GLPG0634 analogue, an analog of Filgotinib (GLPG0634), is a novel, potent and selective Janus kinase-JAK1 inhibitor with potential anti-inflammatory activity. It inhibits JAK1, JAK2, JAK3, and TYK2 with IC50s of 10, 28, 810, and 116 nM, respectively. It has the potential to be used for treating RA-rheumatoid arthritis. It dose-dependently reduces inflammation, cartilage, and bone degradation in the CIA model in rats and mice.

JAK1 (IC50 <100 nM); JAK2 (IC50 <100 nM); JAK3 (IC50 <100 nM); Tyk2 (IC50 <100 nM)

ln Vitro |
JAK-STAT and OSM/IL-lβ pathways are both inhibited by GLPG0634 analog (Compoun 176), with respective EC50 values ranging from 101 to 500 nM[1]. In both rats and humans, the GLPG0634 analog has microsomal stability of 76%–100%[1].

ADME/Pharmacokinetics |
Absorption, Distribution and Excretion
Filgotinib is rapidly absorbed after oral administration. Median peak plasma concentrations occurred 2-3 hours post-dose for filgotinib and 5 hours post-dose for GS-829845. Steady-state concentrations can be observed in 2-3 days for filgotinib and in 4 days for GS-829845. Food does not appear to have a significant effect on the absorption of filgotinib; therefore, the medication can be administered without regard to food. After repeated oral dosing of filgotinib 200 mg, the reported Cmax and AUCτ values of filgotinib were 2.15 ug/mL and 6.77 ugxh/mL, respectively. For GS-829845 (the major metabolite) the reported Cmax was 4.43 ug/mL and the reported AUCτ was 83.2 ugxh/mL. Of the total administered dose of filgotinib, approximately 87% undergoes renal elimination while 15% undergoes faecal elimination. Metabolism / Metabolites Carboxylesterase enzymes are involved in the metabolism of filgotinib. The carboxylesterase 2 (CES2) isoform is chiefly responsible for metabolizing filgotinib to its major metabolite, GS-829845. Although carboxylesterase 1 (CES1) plays a less prominent role in the biotransformation of filgotinib, in vitro studies have demonstrated that CES1 will partially compensate in the event of CES2 saturation. GS-829845 is thus far the only major circulating metabolite to have been identified. Biological Half-Life The half-life of filgotinib is estimated to be 7 hours, while the half-life of its active metabolite GS-829845 is estimated to be 19 hours. |

Toxicity/Toxicokinetics |
Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation Filgotinib is not approved in the United States by the Food and Drug Administration. No information is available on the clinical use of filgotinib during breastfeeding. The European manufacturer recommends that breastfeeding be discontinued during filgotinib therapy. ◉ Effects in Breastfed Infants Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk Relevant published information was not found as of the revision date. Protein Binding Approximately 55-59% of filgotinib is protein-bound, while 39-44% of the active metabolite GS-829845 is protein-bound. |

Pharmacodynamics
In addition to targeted Janus kinase (JAK) 1 inhibition, filgotinib targets pro-inflammatory cytokine signalling by inhibiting IL-6 induced STAT1 phosphorylation. Serum C-reactive protein levels are also reduced in response to filgotinib administration. |

Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
