Brief Description

AG-1024 (Tyrphostin) inhibits IGF-1R autophosphorylation with IC50 of 7 μM, less potent to IR with IC50 of 57 μM.
IC50 value: 7 uM (IGF-1R autophosphorylation); 57 uM (IR)
Target: IGF-1R; IR
in vitro: AG-1024 blocks the IGF-1 receptor and IR autophosphorylation with IC50 of 7 μM and 57 μM, respectively. AG-1024 also inhibits the receptor tyrosine kinase activity towards exogenous substrates (TKA) with IC50 values of 18 μM and 80 μM, respectively. Human breast cancer cell line MCF-7 exposure to Tyrphostin AG 1024 inhibited proliferation and induced apoptosis in a time-dependent manner, and the degree of growth inhibition for IC20 plus irradiation (4 Gy) was up to 50% compared to the control. Examination of Tyrphostin AG 1024 effects on radiation response demonstrated a marked enhancement in radiosensitivity and amplification of radiation-induced apoptosis. AG-1024 significantly inhibits melanoma cell proliferation with an IC50 of <50 nM in the absence of serum, by blocking MAPK/ERK2 signaling, subsequently rapidly inducing pRb dephosphorylation and activation, and eventually the formation of growth suppressive pRb-E2F complexes.
in vivo: Administration of AG-1024 at a dose of 30 μg for 10 days significantly inhibits the tumor growth of Ba/F3-p210 xenograft in mice.
