Sb-202190

DescriptionSB 202190 is a selective, potent, cell-permeable inhibitor of p38 MAP kinases, inhibiting p38α (SAPK2A, MAPK14) and p38β (SAPK2B, MAPK11) with IC50 values of 50 and 100 nM, respectively. When tested at 10 μM, SB 202190 has negligible effects on a range of other kinases, including other MAP kinases (ERKs, JNKs). Pyridinyl imidazole inhibitors, including this compound, directly bind p38 MAP kinases in the ATP binding pocket. Recently, SB 202190 has been used to elucidate the roles of p38 MAP kinases in inflammatory cytokine expression, nicotine-induced receptor expression, and HIV-mediated depressive disorder.

UsesSB 202190 is a DFG inhibitor used in the treatment of colorectal cancer. It is a highly selective, potent inhibitor of p38 MAP kinase. SB-202190 is able to promote proliferation of C6 cells in lower concentration but induced apoptosis in higher levels. Studies show that SB202190 can protect neural function from ischemia/reperfusion injury and regulate the activation of Bcl-2 and Bax protein after ischemia/reperfusion in rat.

General DescriptionA potent, reversible, competitive, 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 (Ki = 16 nM; 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 induce LDL receptor expression in Hep52 cells. A 1 mg/ml solution of SB 202190 (Cat. No. 559397) in anhydrous DMSO is also available.

DefinitionChEBI: A member of the class of imidazoles that is 1H-imidazole in which the hydrogens at positions 2, 4, and 5 are replaced by 4-hydroxyphenyl, pyridin-4-yl, and 4-fluorophenyl groups, respectively. It is a widely used inhibitor of mitogen-act vated protein kinase (MAPK) alpha and beta.
