AG-494 (Tyrphostin AG 494) is a potent and selective EGFR tyrosine kinase inhibitor (IC50=0.7 μM). AG-494 inhibits the autophosphorylation of EGFR, ErbB2, HER1-2 and PDGF-R with IC50s 1.1, 39, 45 and 6 μM, respectively. AG-494 blocks Cdk2 activation and inhibits EGF-dependent DNA synthesis.

How to use

In Vitro:

In DHER-14 cells, AG 494 inhibits Cdk2 activation and EGF-dependent DNA synthesis. AG-494 significantly prevents NF-kB activation in silica-stimulated cells, and also reduces NF-kB activation in H2O2-treated cells. AG-494 (3-9 μM; 5-7 days) inhibits BMP9-induced ALP activity in a dose-dependent manner.
