AL 8697 是一种具有口服活性的特异性 p38α MAPK 抑制剂，IC50 为 6 nM。
AL8697 is a selective p38 MAPK(mitogen-activated protein Kinase) inhibitor, which is also named P38 α inhibitor. It has the function of inhibiting the activity of P38 MAPK.[1]
Mitogen activated protein kinases (MAPK) are a group of signaling molecules that appear to play important roles in inflammatory processes. The P38 MAPK is one of the best described MAPK cascades. The p38 MAPK plays a key role in both the synthesis and the signalling of pro-inflammatory cytokines such as TNFa and IL-6 by monocyte/macrophages. The p38 MAPK are involved in the up-regulation of TNF production by murine macrophages.It has high activity in cardiovascular cells under a variety of cellular stresses. In cardiovascular disease, the P38 MAPK signaling pathways are activated.[2,3]
AL8697 function by the inhibition of P38 MAPK. It regulates a variety of cell activities related with P38 MAPK.
In a rat adjuvant-induced arthritis model, AL8697 exhibited a good anti-inflammatory effect and induced leukocytosis and increased total plasma cholesterol, these properties were evidently at 10 mg/kg. In addition, AL8697 partially restored the platelet count. The complex profile for AL8697 in rat AIA (adjuvant-induced arthritis) is not observed in human RA (rheumatoid arthritis).[1]
