Background:

AG 494 is a potent and selective inhibitor of EGFR with IC50 value of 0.7 μM.


The epidermal growth factor receptor (EGFR) is the cell-surface receptor for epidermal growth factor and plays an important role in tumor invasion and cancer cell proliferation.


AG 494 is a potent and selective EGFR inhibitor. AG 494 inhibited autophosphorylation of EGFR and HER-2 with IC50 values of 1.1 and 39 μM, respectively. In DHER-14 cells, AG 494 inhibited Cdk2 activation and EGF-dependent DNA synthesis [1]. AG494 arrested cells at late G1 and S phase and inhibited the activation of Cdk2 by phosphorylating tyrosine 15 on Cdk2 [2]. Epidermal growth factor (EGF) increased (bone morphogenetic protein) BMP9-induced osteogenic markers of mesenchymal stem cells (MSCs), which was inhibited by AG-494 in a time- and dose-dependent way [3]. In human prostate (DU145) and lung (A549) cancer cell lines, AG494 reversibly and significantly inhibited autocrine growth in a dose-dependent way. Also, AG494 induced cell apoptosis in both cell lines and arrested cell growth in the G1 phase [4].
