PD 98059 - CAS 167869-21-8 - Calbiochem,2ʹ-Amino-3ʹ-methoxyflavone, MEK Inhibitor V

一般描述

Selective, reversible, and cell-permeable inhibitor of MAP kinase kinase (MEK) that acts by inhibiting the activation of MAP kinase and subsequent phosphorylation of MAP kinase substrates (noncompetitive with respect to ATP). Pretreatment of PC-12 cells with PD 98059 completely blocks the 4-fold increase of MAP kinase activity produced by nerve growth factor (NGF; IC50 = 2 μM); however, it has no effect on NGF-dependent tyrosine phosphorylation of the pp140trk receptor or its substrate Shc and does not block NGF-dependent activation of PI 3-kinase. Inhibits cell growth and reverses the phenotype of ras-transformed BALB 3T3 mouse fibroblasts and rat kidney cells.

Blocks LPS-induced activation of TNF-α gene expression. Inhibits cell growth and reverses the phenotype of ras-transformed BALB3T3 mouse fibroblasts and rat kidney cells. A 5 mg/ml solution of PD 98059 (Cat. No. 513001) in anhydrous DMSO is also available.
