产品名称
PD 98059
产品介绍
PD98059 是一种非 ATP 竞争性 MEK 抑制剂,对MEK1和MEK2的IC50为 2和50 μM。它是ERK1/2信号的抑制剂,可抑制细胞自噬。它是芳烃受体的配体,可抑制细胞中 TCDD 结合和AhR转化。
PD 098059 does not inhibit Raf-activated MAPKK1 but that it prevents the activation of MAPKK1 by Raf or MEK kinase in vitro at concentrations (IC50: 2-7 μM). PD 098059 also acts as a specific inhibitor of the activation of MAPKK in Swiss 3T3 cells, suppressing by 80-90% its activation by a variety of agonists [1]. Concentrations of PD98059 of/=10 μM. In vivo exposure of cultures to95%) of the dually phosphorylated forms of the extracellular signal-regulated kinase (IC50: 1 μM) [2].

产品描述

PD98059 is a non-ATP competitive MEK inhibitor (IC50: 2/50 μM for MEK1/MEK2).

体内活性

PD98059 (10mg/kg) was administered 1 and 6h after zymosan administration i.p. PD98059 attenuated the peritoneal exudation and the migration of polymorphonuclear cells caused by zymosan. Treatment of mice with PD98059 (10mg/kg) attenuated the NF-kappaB activation and MAPK expression induced by zymosan injection [3]. Administration of PD98059 (10 mg/kg) 1 h after carrageenan caused a reduction in all the parameters of inflammation measured [4].

激酶实验

c-Raf and MEK kinase were measured by their ability to activate MAPKK1 (or MAPKK2) in a 30-min coupled assay containing MAPKK1 (or MAPKK2) and its substrate p42 MAP kinase. One unit of c-Raf or MEK kinase activity was that amount which increased the activity of p42Graphic by 1 unit/min. MAPKK was assayed directly in the cell lysate by the activation of bacterially expressed p42Graphic. One unit of MAPKK was that amount which increased the activity of p42Graphic by 1 unit/min. The assays of c-Raf and MAPKK are quantitative and extremely sensitive and are detailed elsewhere. p42Graphic was assayed by its ability to phosphorylate myelin basic protein and MAPKAP kinase 1 α/β by the phosphorylation of a peptide related to the C terminus of ribosomal protein S6 [Gly-245, Gly-246]S6-(218-249). One unit of p42Graphic or MAPKAP kinase-1α/β was that amount which catalyzed the phosphorylation of 1 nmol of substrate peptide in 1 min. Protein kinase activities in immunoprecipitates were measured by adding the other assay components to the tubes containing the immunoprecipitated enzyme [1].

细胞实验

The MCF10A-Neo and MCF10A-NeoT lines were derived by transfection of the MCF10A cell line with the pHo6 plasmid and the pHo6 plasmid containing an Ha-ras oncogene derived from the human T24 bladder carcinoma cell line, and subsequent selection for resistance to G418. The transfected lines represent pooled survivors, as opposed to clonal lines. With the exception of the EGF content being increased from 10 to 20 ng/ml, the cells were cultured in supplemented Dulbecco's modified Eagle's medium/Ham's F-12 medium in a humidified atmosphere of 95% air/5% CO2 at 37°C. Subconfluent cultures were treated with varying concentrations of chemicals dissolved in DMSO (absolute volume of solvent< 0.1% of medium volume). Subconfluent cultures are treated with PD98059 (0-100 μM). Viability of cells after treatment was assessed by ability to exclude trypan blue. Cultures earmarked for RNA isolation were washed twice with phosphate-buffered saline (2.7 mM KCl, 1.5 mM KH2PO4, 137mM NaCl, 8 mM Na2HPO4, pH 7.2) at harvesting and stored at 280°C [2].

动物实验

Mice were randomized into 4 groups (n= 40 animals/group): (i) CAR + vehicle group. Mice were subjected to carrageenan-induced pleurisy and received the vehicle for PD98059 (10% dimethylsulfoxide (DMSO) (v/v) i.p. bolus 1 h after carrageen administration(N=10); (ii) PD98059 group. Same as the CAR + vehicle group but were administered PD98059 (10 mg/kg, i.p. bolus) 1 h after carrageenan administration (N=10); (iii) Sham+saline group. Sham-treated group in which identical surgical procedures to the CAR group were performed, except that the saline was administered instead of carrageenan (n=10); (iv) Sham+ PD98059 group. Identical to Sham+saline group except for the administration of PD98059 (10 mg/kg i.p. bolus) 1h after carrageenan administration of saline (N=10). The doses of PD98059 (10 mg/kg) used here were based on previous in vivo studies that demonstrated regulation of the inflammation process [4].
