Beschreibung

General description

A cell-permeable, potent, reversible, ATP-competitive, and specific inhibitor of human p38 MAP Kinase (IC₅₀ = 60 nM). Binds to an extended pocket in the active site of the enzyme. Exhibits over 2000-fold greater selectivity for p38 MAPK over ERK (p42/p44 MAP kinase), 500-fold over PKA, 50-fold over PKC, and >1000-fold over EGFR. Also acts as a potent inhibitor of angiogenesis and as an inhibitor of LPS-induced TNF-α production.

Please note that the molecular weight for this compound is batch-specific due to variable water content.

A potent and specific inhibitor of human p38 mitogen-activated protein (MAP) kinase (IC₅₀ = 60 nM). Binds to an extended pocket in the active site of the enzyme. Exhibits >2500-fold greater selectivity for p38 MAPK over ERK (p42/p44 MAP kinase), 500-fold over PKA, 50-fold over PKC, and >1600-fold over EGFRK. Also acts as a potent inhibitor of angiogenesis and as an inhibitor of LPS-induced TNF-α production.
