BMS-582949 (C09-0785-830)

InformationBMS-582949 BMS-582949 (PS540446) is a potent and selective p38 mitogen-activated protein kinase (p38 MAPK) inhibitor with IC50 of 13nM,inhibiting both p38 kinase activity and activation of p38.Targetsp38 MAPK (Cell-free assay) 13 nMIn vitroBMS-582949 is found to inhibit p38 activation in cells, as measured by phosphorylation of p38. BMS-582949 treatment of cells in which p38 has been activated by LPS rapidly reversed p38 activation as shown by loss of phosphorylation of p38. BMS-582949 is therefore a dual action p38 kinase inhibitor, inhibiting both p38 kinase activity and p38 activation in cells. BMS-582949 binding to p38a results in a conformational change of the activation loop which is phosphorylated by upstream kinases, therefore it inhibits phosphorylation of p38 by upstream MKK by inducing a less accessible conformation of the activation loop.In vivoThe mouse clearance rate for BMS-582949 is 4.4 mL/min/kg. And at an oral dose of 10 mg/kg, the mouse AUC0-8 h for BMS-582949 is 75.5 μM•h. BMS-582949 exhibited oral bioavailability values of 90% and 60% in mice and rats, respectively.
