SB 203580

產品說明:SB203580也寫作SB 203580或SB-203580，是一種常用的p38 MAPK抑制劑。SB203580可以通透細胞，抑制p38 MAPK(p38 MAP kinase)，抑制后續MAPKAP Kinase-2和MAPKAP Kinase-3的激活。通過抑制p38 MAPK，SB203580可以有效抑制一些炎癥因子(如IL-1β、TNF-α)誘導的部分信號轉導。SB203580選擇性抑制p38 MAPK，IC50為600 nM；對于JNK/SAPK和p44/42 MAPK(即Erk1/2)無顯著的抑制作用，IC50僅為100 μM。
     SB203580分子量為377.43，分子式為C₂₁H₁₆N₃FOS，CAS Number：152121-47-6。

4-(4-Fluorophenyl)-2-(4-methylsulfinylphenyl)-5-(4-pyridyl)1H-imidazole

A highly specific, potent, cell-permeable, selective, reversible, and ATP-competitive inhibitor of p38 MAP kinase (IC₅₀ = 34 nM in vitro, 600 nM in cells). Does not significantly inhibit the JNK and p42 MAP kinase at 100 µM. Inhibits IL-1 and TNF-α production from LPS-stimulated human monocytes and the human monocyte cell line THP-1 (IC₅₀ = 50-100 nM). Inhibits bone morphogenetic protein-2-induced neurite outgrowth in PC12 cells. Also inhibits platelet aggregation caused by collagen (IC₅₀ = 0.2-1.0 µM) or the thromboxane analog U-46619 (Cat. No. 538944). A 1 mg/ml solution of SB 203580 (Cat. No. 559398) in anhydrous DMSO is also available.
