IGF-1R inhibitor-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.
NBI-31772 hydrate is a powerful inhibitor of the interaction between insulin-like growth factor (IGF) and IGF-binding proteins (IGFBPs). It acts as a nonpeptide ligand, effectively releasing bioactive IGF-I from the IGF-I IGFBP-3 complex (Ki values for all six human subtypes range from 1-24 nM). This compound demonstrates significant anxiolytic and antidepressant-like effects [1] [2] [3].
NVP-ADW742 is an IGF-1R inhibitor 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.
