p38 MAPK-IN-3 (Compound 2c) is a potent inhibitor of p38α MAPK, displaying antitumor properties by promoting apoptosis and increasing reactive oxygen species (ROS) production [1].
AMG-548 dihydrochloride is an orally active and selective p38α inhibitor (Ki: 0.5 nM) and shows slightly selective over p38β (Ki: 36 nM) and >1000 fold selective against p38γ p38δ. It is also extremely potent in the inhibition of whole blood LPS stimulate
Ralimetinib selectively inhibits phosphorylation of MK2 (Thr334) and has no effect on phosphorylation of p38α MAPK, JNK, ERK1 2, c-Jun, ATF2, or c-Myc. Ralimetinib is an effective and selective, ATP-competitive inhibitor of p38 MAPK α β (IC50s: 5.3 and 3.
