CMPD1 is a selective and non-ATP-competitive p38 MAPK-mediated MK2 phosphorylation inhibitor with apparent Ki (Kiapp) of 330 nM[1][2].
CMPD1 does not inhibit p38 MAPK-mediated phosphorylation of other two substrates, MBP and ATF2[1].CMPD1 induced mitotic arrest and apoptosis in U87 cells[1].CMPD1 inhibits tubulin polymerisation in glioblastoma cells[3].
