Application

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.

Biochem/physiol Actions

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.

MAPKs

The mitogen-activated protein kinase (MAPK) family consists of both stress activated (SAPK) and mitogen-activated (MAPK) protein kinases. They form a network of signal transduction cascades that mediate cellular responses to a diverse range of stimuli, including growth factors, chemical or osmotic stress, irradiation, bacterial infection and proinflammatory cytokines.
