SB202190 is a pyridinyl imidazole that inhibits p38 kinase in vivo through competition with ATP. It binds within the ATP pocket of the active kinase and selectively inhibits p38α and β isoforms. SB202190 induces apoptosis through the activation of cysteine protease (CPP32) like kinases.  SB202190 has been shown to block both lipopolysaccharide (LPS) induced gene expression and nitric oxide (NO) induced stabilization of interleukin (IL) -8 mRNA in monocytes.
