SB 203580 (hydrochloride) Chemical Properties, Uses, Production
Uses
SB 203580 Hydrochloride is a protein kinase inhibitor.
General Description
A water-soluble form of the potent MAP kinase inhibitor SB 203580 (Cat. No. 559389).
Biological Activity
sb203580 hcl is a specific inhibitor of p38-mapks with ic50 value of 0.6 μm [1].sb203580 is an inhibitor of p38-mapkα and p38-mapkβ. in neonatal myocytes, sb203580 prevented p38-mapk from activating mapkapk2 with ic50 value of 70 nm. it also significantly suppressed mapkapk2 activation in by il-1, osmotic stress or arsenite in kb cells. in neonatal rat ventricular myocytes, sb203580 inhibited jnk activity of activating c-jun with ic50 value of 3-10 μm. besides that, sb203580 affected the phosphorylation of small heat shock proteins caused by mapkapk2. it inhibited the il-1-, chemical- or osmotic stress-stimulated hsp27 phosphorylation with ic50 value of < 1μm in kb cells [1, 2].
Biochem/physiol Actions
Cell permeable: yes
storage
