Replaces Prod. #: ALX-270-259

Cell permeable, potent and selective p38 MAP kinase inhibitor (IC50=30 nM). Inhibits p38α and ß, but not γ and δ isoforms. Does not inhibit ERK2 or other members of the MAP kinase family or their upstream activators. A useful tool for dissecting the role of p38 in signaling pathways. Induces apoptosis.
