UsesPD 158780 is a potent tyrosine kinase inhibitor of the epidermal growth factor receptor and has been shown to delay substantial growth of tumors in vivo tumor models.
General DescriptionA potent inhibitor of the EGFR tyrosine kinase activity (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 1/2 (MKK1/2) activation and EGFR tyrosine phosphorylation in HeLa and NIH3T3 cells.

DefinitionChEBI: PD158780 is a pyridopyrimidine that is pyrido[3,4-d]pyrimidine-4,6-diamine in which the amino groups at positions 4 and 6 are substituted by a m-bromophenyl group and a methyl group, respectively. It is a potent, cell-permeable, reversible ATP-competitive inhibitor of EGFR tyrosine kinase activity [IC50 values of 0.008, 49 and 52 nM for EGFR, ErbB2 (HER2) and Erb4 (HER4)]. It does not inhibit FGF or PDGF-mediated tyrosine phosphorylation. Induces G1 cell cycle arrest in MCF10A cells and is antiproliferative in A431 human epidermal carcinoma cells. It has a role as an antineoplastic agent and an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor. It is a pyridopyrimidine, a secondary amino compound, a member of bromobenzenes, a diamine and an aromatic amine.
