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.

NVP-AEW541 (AEW541) 是一种IGF-1R 抑制剂，IC50为 0.15 μM。它也抑制InsR，IC50为 0.14 μM。
