| Hazard Information | Back Directory | [Description]
Protein tyrosine kinase (PTK) inhibitors are potential antiproliferative agents for diseases caused by the hyperactivity of PTKs. Tyrphostins are a class of antiproliferative, compounds that act as PTK blockers. PTK inhibitors that preferentially inhibit the epidermal growth factor (EGF) receptor kinase block EGF-dependent cell proliferation. AG-494 is an inhibitor of epidermal growth factor receptor kinase with an IC50 value of 1 μM in HT-22 cells. | [Uses]
AG-494 is a member of the tyrphostin family of tyrosine kinase inhibitors and is a potent inhibitor of EGF receptor autophosphorylation (IC50=1.2 μM) and EGF-dependent cell growth (IC50=6 μM). It selectively inhibits HER1 (EGF receptor) vs. HER1-2 receptor autophosphorylation (HER1: IC50=1.1 μM; HER1-2: IC50=45 μM). HER1-2 is a chimeric receptor consisting of the external HER1 domain fused to an internal HER2 domain. Blocks CDK2 activation and causescells to arrest at late G1 and during S phase. | [Biological Activity]
Potent inhibitor of epidermal growth factor receptor (EGFR) kinase (IC 50 = 0.7 μ M). Selective over ErbB2, PDGFR and insulin receptor kinase (IC 50 values are 42, 6 and > 100 μ M respectively). | [References]
