VX-745 is a lead anti-inflammatory candidate, p38 MAPK inhibitor (IC50=10 nM) for the treatment of Rheumatoid arthritis (RA). p38 MAPK is a specific enzyme that regulates the production of IL-1, IL-2, IL-6, TNFα, chemokines and nitric oxide (NO), as part of acute and chronic inflammatory responses.In vitro, VX-745 was selective for p38 MAPK compared to a large panel of kinases (IC50≥20µM). VX-745 selectively inhibited p38α MAPK (IC50=10 nM), p38β MAPK (IC50 =220 nM) , but not p38γ MAPK (IC50≥20 µM). In addition, cell data for VX-745 provided IC50 values of 56 and 52 nM for IL-1β and TNFα, respectively, and VX-745 blocked IL-6 and IL-8 production induced by IL-1 and TNFα. In a human whole blood assay, IC50 values were 152 and 177 nM for IL-1β and TNFα inhibition, respectively.
