IGF-I is partly responsible for systemic GH activities although it possesses a wide number of own properties (anabolic, antioxidant, anti-inflammatory and cytoprotective actions).IGF-I (24-41) (TFA) is amino acids 24 to 41 fragment of Insulin-like Growth
IGF-I (24-41) is a 24-41 amino acid fragment of Insulin-like Growth Factor I (IGF-I), which contributes to systemic GH activities and exhibits various properties such as anabolic, antioxidant, anti-inflammatory, and cytoprotective.
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-IIGFBP-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].
BMS-554417 is a novel inhibitor of IGF-IR, which inhibits IGF-IR and insulin receptor kinase activity and proliferation in vitro, and reduces tumor xenograft size in vivo. In a series of carcinoma cell lines, the IC50 for proliferation ranged from 120 nmol L (Colo205) to >8.5 micromol L (OV202). BMS-554417 treatment inhibited IGF-IR and insulin receptor signaling through extracellular signal-related kinase as well as the phosphoinositide 3-kinase Akt pathway, as evidenced by decreased Akt phosphorylation at Ser473. At doses that inhibited proliferation, the compound also caused a G0-G1 arrest and prevented nuclear accumulation of cyclin D1 in response to LR3 IGF-I. In Jurkat T-cell leukemia cells, this agent triggered apoptotic cell death via the mitochondrial pathway. BMS-554417 was orally bioavailable and significantly inhibited the growth of IGF1R-Sal tumor xenografts in vivo. BMS-554417 is a member of a novel class of IGF-IR insulin receptor inhibitors that have potential......
AEW541, also known as NVP-AEW541, is a novel, potent IGF-IR kinase inhibitor. NVP-AEW541 is capable of distinguishing between the IGF-IR (IC50 = 0.086 microM) and the closely related InsR (IC50 = 2.3 microM) in cells. NVP- AEW541 abrogates IGF-I-mediated survival and colony formation in soft agar at concentrations that are consistent with inhibition of IGF-IR autophosphorylation. Note: AEW541 has a Cis-configuration on the cyclobutane ring. Its CAS# is 475489-16-8. Many vendors and Sc-finder scholar made mistake - AEW541 was mistakenly listed as CAS#475488-34-7, the trans-isomer of AEW541. The correct structure of AEW541 can be confirmed from Joel Slade, et al (from Novartis), Org. Process Res. Dev. 2007, 11, 5, 825–835.
