product name VX-702
Description: VX-702 is a highly potent and selective inhibitor of p38α MAPK, 14-fold higher potency against the p38α versus p38β. It is one of a series of second-generation and orally active p38 MAP kinase inhibitors that are used 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.

In vitro activity: Pre-incubation of platelets with VX-702 (1 μM) completely or partially inhibits p38 activation (IC50 4 to 20 nM) induced by platelet agonists including thrombin, SFLLRN, AYPGKF, U46619 and collagen. VX-702 shows no effect on platelet aggregation induced by any of the p38 MAPK agonists in the presence or absence of anti-platelet therapies. VX-702 inhibits the production of IL-6, IL-1β and TNFα (IC50 = 59, 122 and 99 ng/mL, respectively) in a dose-dependent manner. Kinase Assay: Pre-incubation of platelets with VX-702 (1 μM) completely or partially inhibits p38 activation (IC50 4 to 20 nM) induced by platelet agonists including thrombin, SFLLRN, AYPGKF, U46619 and collagen. VX-702 shows no effect on platelet aggregation induced by any of the p38 MAPK agonists in the presence or absence of anti-platelet therapies. VX-702 inhibits the production of IL-6, IL-1β and TNFα (IC50 = 59, 122 and 99 ng/mL, respectively) in a dose-dependent manner. Cell Assay: 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. |

| In Vivo | The half-life of VX-702 is 16 to 20 hours, with a median clearance of 3.75 L/h and a volume of distribution of 73 L/kg. Both AUC and Cmax values are dose proportional for VX-702, which is predominantly cleared renally. VX-702 (at a dose of 0.1 mg/kg twice daily) has an equivalent effect as that of methotrexate (0.1 mg/kg). In addition, VX-702 (5 mg/kg twice daily) also has an equivalent effect as prednisolone (10 mg/kg once daily), as measured by percentage inhibition of wrist joint erosion and inflammation score. VX-702 selectively inhibits activation of p38 MAPK after ischemia with no effects on ERKs and JNKs. The MI/AAR ratio is significantly reduced in the 50 mg/kg group compared with the 5 mg/kg and vehicle groups. |
