ABSTRACT
|
|
|
| |
|
Janus kinases (JAK1, JAK2, JAK3, and TYK2) are involved in the signaling of
multiple cytokines important in cellular function. Blockade of the JAK-STAT
pathway with a small molecule has been shown to provide therapeutic
immunomodulation. Having identified JAK1 as a possible new target for arthritis
at Galapagos, the compound library was screened against JAK1, resulting in the
identification of a triazolopyridine-based series of inhibitors represented by
3. Optimization within this chemical series led to identification of GLPG0634
(65, filgotinib), a selective JAK1 inhibitor currently in phase 2B development
for RA and phase 2A development for Crohn's disease (CD).
