SB202190 |
SB202190 is a potent p38 MAPK inhibitor targeting p38α/β with IC50 of 50 nM/100 nM in cell-free assays, sometimes used instead of SB 203580 to investigate potential roles for SAPK2a/p38 in vivo. SB202190 inhibits endothelial cell apoptosis via induction of autophagy and heme oxygenase-1. SB202190 significantly suppresses Erastin‐dependent ferroptosis. |

Pamapimod |
Pamapimod (R-1503, Ro4402257) is a novel, selective inhibitor of p38 mitogen-activated protein kinase. It inhibits p38α and p38β enzymatic activity with IC50 values of 0.014±0.002 and 0.48± 0.04 microM, respectively with no activity against p38delta or p38gamma isoforms. |
