Filgotinib

CAS#: 1206161-97-8

Description: Filgotinib, also known as GLPG0634, is a potent and selective JAK1 inhibitor under investigation for the treatment of rheumatoid arthritis (RA) and Crohn’s disease. It is considered a promising agent as it inhibits JAK1 selectively. Filgotinib displayed a selectivity of 30-fold for JAK1- over JAK2-dependent signaling. GLPG0634 dose-dependently inhibited Th1 and Th2 differentiation and to a lesser extent the differentiation of Th17 cells in vitro.

Synonym: GLPG0634; GLPG 0634; GLPG-0634. Filgotinib; PubChemSID 163643231

IUPAC/Chemical Name: N-(5-(4-((1,1-dioxidothiomorpholino)methyl)phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl)cyclopropanecarboxamide.
