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.
How to use:
In Vitro: GLPG0634 dose-dependently inhibits the differentiation of Th2 cells mediated by IL-4, a cytokine that signals through JAK1 and JAK3. GLPG0634 also inhibits Th1 differentiation with similar potencies of 1 μM or lower. GLPG0634 does not inhibit JAK2 homodimer-mediated signaling induced by EPO or PRL (IC50 > 10 μM).
In Vivo: GLPG0634 (3, 10, 30 mg/kg, p.o.) dose-dependently prevents disease progression in the therapeutic rat CIA model. GLPG0634 (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. GLPG0634 (0.1 and 0.3 mg/kg) shows efficacy in the rat CIA model.
