Description

General description

A potent and cell-permeable inhibitor of p38 MAP kinase. Inhibits p38 phosphorylation of myelin basic protein (MBP) with no effect on the activity of the ERK or JNK MAP kinase subgroups. Also inhibits the kinase activity of p38β (IC₅₀ = 350 nM) and p38 phosphorylation of activating transcription factor 2 (ATF-2; IC₅₀ = 280 nM). Blocks LPS-induced TNF-α and interleukin biosynthesis. Reported to block LDL expression in Hep52 cells.

Biochem/physiol Actions

Cell permeable: yes

Primary Target
P38β

Product competes with ATP.

Reversible: yes

Target K_i: 350 nM against the kinase activity of p38β; 280 nM against p38 phosphorylation of activating transcription factor 2 (ATF-2)
