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

Packaging

Packaged under inert gas

The transmembrane serine protease matriptase is a key regulator of both barrier-disruptive and protective epithelial cell-cell interactions. Elevated matriptase is a consistent feature of epithelial ovarian cancers (OvCa), where multicellular spheroids shed from the primary tumor into the peritoneal cavity
