SB239063是一种有效的p38 MAPK选择性抑制剂,对p38αMAPK的IC50为44 nM。SB239063对γ-和δ-激酶没有活性[1]。
体外实验:在氧-葡萄糖剥夺的海马切片培养物中,20 μM和100 μM SB239063显著降低促炎细胞因子IL-1β的水平,并且在氧-葡萄糖剥夺后减少细胞死亡并显著减少小胶质细胞活化[2]。
在体实验:在脂多糖(LPS)吸入后48小时,3-30 mg/kg SB 239063每天两次口服给药,SB 239063以剂量依赖性方式抑制气道中性粒细胞浸润和白细胞介素(IL)-6水平(1)。在博来霉素诱导的肺纤维化大鼠模型中,通过渗透泵给予SB 239063 2.4或4.8 mg/天,显著抑制博来霉素诱导的右心室肥大(意味着继发性肺动脉高压),并增加肺羟脯氨酸合成(意味着胶原合成和纤维化)(1)。在清醒的豚鼠中,抗原后24小时通过BAL测量发现,口服给药SB 239063(10或30 mg/kg)显著降低OA诱导的肺嗜酸性粒细胞流入约50%(1)。在LPS暴露后6小时评估发现,口服SB 239063(30 mg/kg)减弱支气管肺泡灌洗液IL-6浓度(> 90%抑制)和MMP-9活性(64%抑制)。在培养的豚鼠肺泡巨噬细胞中,SB 239063抑制LPS诱导的IL-6产生,IC50为362 nM。在脂多糖刺激的人外周血单核细胞中,SB 239063抑制IL-1和TNF-α产生,IC50分别为0.12和0.35 μM(2)。
