Description

General description

A potent, cell-permeable, reversible, ATP-competitive inhibitor of the EGFR tyrosine kinase activity (IC₅₀ = 8 pM). Also inhibits heregulin-stimulated autophosphorylation in SK-BR-3 (IC₅₀ = 49 nM) and MDA-MB-453 (IC₅₀ = 52 nM) breast carcinomas. The inhibition is competitive and results from binding of the inhibitor at the ATP site of the enzymes. Inhibits the LPA-stimulated MAP kinase kinase ½ (MKK½) activation and EGFR tyrosine phosphorylation in HeLa and NIH3T3 cells.

The inhibition is competitive and results from binding of the inhibitor at the ATP site of the enzymes. Inhibits the LPA-stimulated MAP kinase kinase 1/2 (MKK1/2) activation and EGFR tyrosine phosphorylation in HeLa and NIH 3T3 cells. A 10 mM (500 µg/151 µl) solution of PD 158780 (Cat. No. 513036) in DMSO is also available.
