SB 202190 is a cell permeable pyridinyl imidazole, which acts as a strong inhibitor of SAPK2a/p38 and SAPK2b/p38beta MAP kinases (IC50=280nM and 350nM, respectively). SB 202190 has no effect on the activity of the Erk or SAPK/JNK MAP kinases and is reported to block LPS induced TNF-a and IL-1beta production in mice. The compound is a slightly better inhibitor than the related compound SB 203580. Solubility: Soluble in DMSO (50mg/ml). Applications: Specific inhibitor of p38/SAPK2a MAPK and P38b/SAPK2a MAPK activity. Other applications not tested. Protein Kinase Inhibition Assay: When pre-incubated for five minutes with 0.2ug of SAPK2a/p38 MAPK or SAPK2b/p38beta MAPK, 1-10uM of SB 202190 will inhibit the activity of these kinases 80-95%. The final concentration of SB 202190 needed may depend on the amount of enzyme used. Optimal dilutions to be determined by the researcher. Storage and Stability: Stable for at least 12 months at -20°C in the dark. After reconstitution, aliquot and freeze at -20°C, away from light.
