| Bioactivity | NBI-31772 hydrate is a potent inhibitor of interaction between insulin-like growth factor (IGF) and IGF-binding proteins (IGFBPs). NBI-31772 hydrate is also a nonpeptide ligand that releases bioactive IGF-I from the IGF-I/IGFBP-3 complex (Kis=1-24 nM for all six human subtypes). Anxiolytic and antidepressant-like effects[1][2][3]. |
| In Vivo | NBI-31772 (5-100 μg; icv; immediately or at 1, 2, or, 3 hours after MCAO) at the time of ischemia onset also dose-dependently reduced infarct size, and the highest dose (100 μg) significantly reduced both total and cortical infarct volume[3]. Animal Model: |
