          SB 203580是一種吡啶咪唑類p38 MAPK抑制劑(IC50=0.3-0.5 µM)。SB 203580抑制IL-2誘導(dǎo)的T細(xì)胞增殖(IC50=3-5 µM),激活人肝細(xì)胞中ERK和JNK的表達(dá),并激活下游ERK-P、JNK-P和c-Jun-P表達(dá)。SB 203580參與多種炎癥反應(yīng)和細(xì)胞應(yīng)激反應(yīng)。另外,SB 203580通過抑制RIPK2表達(dá)從而降低DENV感染的HepG2細(xì)胞凋亡,并誘導(dǎo)人肝癌細(xì)胞自噬作用。在BALB/c小鼠中,SB 203580降低子宮內(nèi)膜病變的重量和大小,并降低腹膜細(xì)胞中IL-1β、TNF-α、MMP-2和MMP-9 mRNA水平。
