Chemical structure

GLPG0634

Protocol

Cell experiment [1]:

Cell lines

THP-1 cells (ATCC TIB-202)

Preparation method

The solubility of this compound in DMSO is >21.3mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

1 μM

Applications

In THP-1 cells, GLPG0634 preferentially inhibited JAK signaling complexes containing JAK1 and also inhibited Th1 differentiation with similar potencies of 1 μM or lower.

Animal experiment [2]:

Animal models

Male Sprague Dawley rats (180–200 g) and CD1 mice (23–25 g)

Dosage form

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)

Application

GLPG0634 dose-dependently reduced inflammation, cartilage, and bone degradation in the CIA model in rats and mice with significant effect of 3 mg/kg. Protection from bone damage was evidenced by a dose-dependent reduction, with significant effect from GLPG0634 (3 mg/kg), showed a marked reduction of the infiltration of inflammatory cells while protecting the articular cartilage and bone from 1 mg/kg onward.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

GLPG0634 is a selective inhibitor of JAK1 with IC50 value of 10nM [1].

GLPG0634 is a small molecule inhibitor of JAK1. It shows potent inhibitory activity against both JAK1 and JAK2 with IC50 values of 10nM and 28nM, respectively. In cellular assays, GLPG0634 is most potent in inhibiting the JAK1/JAK3/γc signaling induced by IL-2– and IL-4 as well as the JAK1/TYK2 type II receptor signaling induced by IFN-αB2. However, it shows lower potent to inhibit JAK2 homodimer–mediated signaling induced by EPO or PRL. It demonstrates that GLPG0634 is specific to JAK1. In addition, GLPG0634 is found to inhibit the phosphorylation of STAT1 and STAT5 induced by cytokines. Moreover, GLPG0634 inhibits the differentiation of Th1 and Th2 cells with similar potencies. Th17 differentiation is also affected by GLPG0634 with a lower potency [1].

In the rat model of collagen-induced arthritis (CIA), oral administration of GLPG0634 shows a marked protection from bone damage at dose of 3 mg/kg. It reduces the infiltration of inflammatory cells significantly from 1 mg/kg onward [1].
