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(xì)胞，抑制p38 MAPK(p38 MAP kinase)，抑制后續(xù)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(dǎo)的部分信號(hào)轉(zhuǎn)導(dǎo)。SB203580選擇性抑制p38 MAPK，IC50為600 nM；對(duì)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。本產(chǎn)品純度大于99%。
