PD98059
目录号 : KM6962 CAS No. : 167869-21-8 纯度 : 98%

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 还可抑制细胞自噬 (autophagy)。

生物活性

PD98059 is a potent and selective MEK inhibitor with an IC50 of 5 µM. PD98059 binds to the inactive form of MEK, thereby preventing the activation of MEK1 (IC50 of 2-7 µM) and MEK2 (IC50 of 50 µM) by upstream kinases. PD98059 is a ERK1/2 signaling inhibitor. PD98059 is a ligand for the aryl hydrocarbon receptor (AHR), and suppresses TCDD binding (IC50 of 4 μM) and AHR transformation (IC50 of 1 μM). PD98059 also inhibits autophagy.

体外研究

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.

Cell Cycle Analysis

Cell Line: OCI-AML-3 cells
Concentration: 20 μM
Incubation Time: 24 hours
Result: Caused G1-phase cell cycle arrest.

Western Blot Analysis

Cell Line: MCF10A-Neo, MCF10ANeoT cells
Concentration: 10 μM
Incubation Time: 22 hours
Result: Phosphorylated ERK forms were almost completely eliminated in both cell lines.
体内研究

PD98059 (10 mg/kg; i.p.; 1 and 6 hours after Zymosan) significantly reduces the level of p-ERK1/2 in zymosan-injected mice.

Animal Model: Male CD mice
Dosage: 10 mg/kg
Administration: Intraperitoneal injection; 1 and 6 hours after Zymosan
Result: Significantly reduced the level of p-ERK1/2.
