AG1024 is an inhibitor of insulin-like growth factor-1 receptor (IGF-1R) and insulin receptor (IR) that specifically inhibits autophosphorylation of IGF-1R and IR with IC50 values of 7μM and 57 μm, respectively [1].

AG1024 has shown to inhibit IGF-1- and insulin-stimulated cellular proliferation in NIH-3T3 mouse fibroblast cells with IC50 values of 0.4μM and 0.1μM, respectively. Additionally, AG1024 shows to block tyrosine kinase activity towards exogenous substrates (TKA) with IC50 values of 18μM and 80μM [1].

AG1024 has been reported to block receptor tyrosine kinase activity, resulting in abolishment of MAPK and Akt pathways and inhibition of cell growth. Moreover, studies showed that AG1024 concentration-dependently inhibited E2 stimulation in MCF-7:PF cells [2].

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reaction Conditions

10 nM, 5 days for cell proliferation inhibition 10 nM, 48 hours for apoptosis induction


The Tyrphostin AG-1024 induced a marked decrease of cell proliferation in a time-dependent manner. It also potently induced cell apoptosis with a 20.1 % of apoptotic cells.

Animal experiment : [2]

Animal models

Female nude mice implanted with Ba/F3-p210 cells

Dosage form

Intraperitoneal injection, 30 μg in100 μl, once per day for 10 days


After injection with Ba/F3-p210 cells (Bcr-Abl expressing cells), nude mice were injected after 6 days with PBS 0.1 ml (control) or Tyrphostin AG1024 30 μg/100 μl (1 μl of 980 μM). The growth of the Ba/F3-p210 xenografts was significantly delayed when mice were treated with Tyrphostin AG1024.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
