PD98059
CAS No. : 167869-21-8
MCE 国际站:PD98059
产品活性:PD98059 是一种有效的选择性的 MEK 抑制剂,IC50 为 5 μM。PD98059 与 MEK 的无活性形式结合,从而阻止上游激酶激活 MEK1 (IC50 为 2-7 μM) 和 MEK2 (IC50 为 50 μM)。PD98059 是一种 ERK1/2 信号的抑制剂。PD98059 是一种芳烃受体 (AHR) 的配体,可抑制细胞中 TCDD 结合 (IC50 为 4 μM) 和 AHR 转化 (IC50 为 1 μM)。PD98059 还可抑制 Mycobacterium bovis Bacillus CalmetteGuerin (BCG) 诱导的细胞自噬 (autophagy)。
研究领域:MAPK/ERK Pathway | Stem Cell/Wnt | Immunology/Inflammation | Autophagy
作用靶点:MEK | ERK | Aryl Hydrocarbon Receptor | Autophagy
In Vitro: PD98059 (20 μM; 24 hours) causes G1-phase cell cycle arrest in OCI-AML-3 cells.
PD98059 (10 μM; 22 hours) results in concentration-dependent reductions in the dually phosphorylated forms of ERK1 and ERK2. PD98059 both prevents ERK activation and blocks formation of TDP-43 and HuR-positive SGs.
In Vivo: PD98059 (10 mg/kg; i.p.; 1 and 6 hours after Zymosan) significantly reduces the level of p-ERK1/2 in zymosan-injected mice.
