SB202190 p38 MAPK inhibitor

Cat.No.S1077

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. This compound inhibits endothelial cell apoptosis via induction of autophagy and heme oxygenase-1. It significantly suppresses Erastin‐dependent ferroptosis.

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
