IGF-1Rinhibitor-2 (example 121) is a compound that inhibits the insulin-like growth factor-1 receptor (IGF-1R). By downregulating the IGF-1R, it has the potential to reverse the transformed phenotype of tumor cells and make them more susceptible to apoptosis.
NVP-ADW742 is an IGF-1Rinhibitor with IC50 of 0.17 μM, >16-fold more potent against IGF-1R than InsR; little activity to HER2, PDGFR, VEGFR-2, Bcr-Abl and c-Kit.
