Description | Tyrphostin AG490 is a selective inhibitor of EGF receptor tyrosine kinase with an IC50 values of 2 and 13.5 μM for EGFR and ErbB2 respectively. AG490 is also a JAK3/STAT, JAK3/AP-1 and JAK3/MAPK signaling pathway inhibitor and also blocks JAK3 autophosphorylation. AG-490 significantly inhibits the constitutive activation of Stat3 in MOPC, MPC11, and S194 cells, leading to dramatic dose-dependent apoptosis. AG-490 (100 μM) inhibits Akt phosphorylation, inhibits the activation of nuclear factor-κB, and causes the activation of GSK-3β, leading to the reduction of c-Myc. AG-490 (50 μM) can induce apoptosis of imatinib-resistant BaF3 cells expressing T315I and E255K mutants of Bcr-Abl. | ||
