CAS#: 745833-23-2 (or 479543-46-9)

Description: VX-702, one of a series of second-generation, is an orally active p38 MAP kinase inhibitors, for the potential treatment of inflammation, rheumatoid arthritis and cardiovascular diseases. VX-702 prevents activation of p38MAPK and decrements in many platelet storage parameters after exposure to 16 °C without agitation for 24 h.

Additional Information

p38 MAPK increases thromboxane levels by activating phospholipase A2, thus catalyzing the formation of arachidonic acid. VX-702 inhibited activation of p38 MAPK by thrombin, SFLLRN, AYPGKF and U46619 in platelets. Kuliopulos, A., et al. "Effect of selective inhibition of the p38 MAP kinase pathway on platelet aggregation." Thromb. Haemost. 92: 1387-1393 (2004). VX-702 showed modest clinical efficacy and transient suppression of biomarkers of inflammation in patients with rheumatoid arthritis. Damjanov, N., et al.
