SB 202190, Tocris Bioscience™

Description

Potent, selective inhibitor of p38 MAPK

SB 202190 is a highly selective, potent and cell-permeable inhibitor of p38 MAP kinase. Binds within the ATP pocket of the active kinase (Kd = 38 nM, as measured in recombinant human p38), and selectively inhibits the p38α and β isoforms (IC50 = 50 and 100 nM at SAPK2a/p38 and SAPK2b/p38β2 respectively). Promotes stability of naive human pluripotent stem cells in culture. Inhibits Yamanaka factor reprogramming of human fibroblasts to iPSCs. SB 202190 improves the self-renewal ability of neuronal stem cells from NPC1-deficient mice.
