GtoPdb Ligand ID: 9848

Synonyms: compound 183 [WO2007138072A2]
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: This compound was developed by Galapagos as a MAPKAPK5 inhibitor, in the search for a novel anti-inflammatory mechanism that would be applicable to the treatment of rheumatoid arthritis (RA). The discovery pathway is detailed in the pdf entitled 'Discovery of inhibitors of MAPKAPK5, a novel target for rheumatoid arthritis', which is available online here. The chemical structure is claimed in Galapagos patent WO2007138072A2, as compound 183 [2]. This compound (compound D) is likely to be a relation of the Galapagos clinical candidate GLPG0259, which failed in Phase 2 clinical trial in patients with methotrexate-refractory RA [3].
