Doramapimod is a highly selective p38alpha MAPK inhibitor to TNF-alpha with EC50 of 18 nM. At 10 muM, doramapimod inhibits JNK2 in vitro, but at the low concentration necessary to inhibit p38alpha, it does not affect the phosphorylation of JNK substrates in cells. Doramapimod is an inhibitor of Raf-1.
