Background:

VX-702 is a selective inhibitor of p38α MAPK with IC50 value ranges from 4 nM to 20 nM [1].

P38 mitogen-activated protein kinases (p38 MAPK), also named as MAPK14, are a class of mitogen-activated protein kinases and play an important role in a signaling cascade controlling cellular responses to cytokines and stress [1-3].

VX-702 is a potent p38α MAPK inhibitor and is designed as for greater affinity and greater selectivity compared with the first reported p38α MAPK inhibitors. When tested with PLTs (platelets), VX-702 caused better maintenance of PLT mitochondrial, functional, structural and metabolic parameters during 7 days storage and restored PLTs properties following an extended interruption of agitation to levels of continuously agitated PLTs [2, 4].

In the isolated perfused rat kidney (IPRK) model, administration of VX-702 at a range of doses between 100 and 600 ng/mL showed linear excretion and the clearance data were consistent with net reabsorption by the kidney. Further, VX-702 was showed not a substrate for renal organic anion and organic cation transport systems [3].
