Description_x000D_ Application_x000D_ p38 MAP Kinase Inhibitor IV has been used for blocking p38α kinase activation in order to examine if HOXB7 is involved in the regulation of migration and proliferation process via AKT/MAPK signaling._x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ p38 MAP Kinase Inhibitor IV is an ATP-competitive inhibitor of p38α/β MAPK with IC50 values of 130 nM for p38α and 550 nM for p38β. It is much less active with ≤23% inhibition at 1 μM against p38γ/σ, ERK1/2, and JNK1/2/3. Shown to be more effective than SB 203580 in inhibiting LPS-induced IL-1β release from hPBMC (100% vs. 50% inhibition with 100 μM inhibitor). A recent study showed that p38 MAP Kinase Inhibitor IV could consistently and significantly enhance reprogramming and iPS cell generation from somatic cells._x000D_ Features and Benefits_x000D_ This compound is featured on the MAPKs page of the Handbook of Receptor Classification and Signal Transduction.
