Description: Potent, selective inhibitor of p38 MAPK

Chemical Name: 4-[4-(4-Fluorophenyl)-5-(4-pyridinyl)-1H-imidazol-2-yl]phenol

Purity: ≥99% (HPLC)

Biological Activity Technical Data Solubility Calculators Datasheets References

Biological Activity

A highly selective, potent and cell-permeable inhibitor of p38 MAP kinase. Binds within the ATP pocket of the active kinase (K_d = 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. Also available as part of the MAPK Inhibitor Tocriset™.
