Biological Activity

NVP-AEW541 is more selective and shows 27-fold more potent than InsR at the cellular level. NVP-AEW541 suppresses the IGF-I-mediated survival, soft agar and proliferation of MCF-7 cells with IC50 of 0.162 μM, 0.105 μM and 1.64 μM, respectively. NVP-AEW541 also reduces the level of phospho-IGF-1R and phospho-PKB in NWT-21 cells.NVP-AEW541 inhibits IGF-I-mediated receptor activation and downstream signaling. Ewing's sarcoma cells were generally found to be more sensitive to the effects of this compound compared with rhabdomyosarcoma and osteosarcoma, in agreement with the high dependency of this neoplasm to IGF-IR signaling. NVP-AEW541 induced a G1 cell cycle block in all cells tested, whereas apoptosis was observed only in those cells that show a high level of sensitivity. NVP-AEW541 represents a class of selective, small molecule IGF-IR kinase inhibitors with proven in vivo antitumor activity and potential therapeutic application.

Results Both NVP-AEW541 (1 μM) and rapamycin (10 nM) notably increased the expression level of the autophagy-related protein Beclin-1 and the ratio of LC3-II/LC-I and reduced the level of the selective autophagy substrate p62.
Cell Experiment
Cell lines MCF-7 cells
Preparation method Seeding between 3 × 103 and 6 × 103 cells/well in 96-well plates with a total media volume of 100 μL/well. Adding increasing concentrations of NVP-AEW541 24 hours thereafter in quadruplicate. After 72 hours , fixing cells by addition of 25 μL/well Glutaraldehyde (20%) and incubation for 10 min at RT. Then washing cells 2× with 200 μL/well H2O and adding 100 μL Methylene Blue (0.05%) . After incubation for 10 min at RT, washing cells 3× with 200 μL/well H2O. adding 200 μL/well HCl (3%) , and following incubation for 30 min at RT on a plate shaker, absorbance is measured at 650 nm.

Animal models Female Harlan athymic nude mice weighing 18-25 g with NWT-21 cells
Formulation Dissolved in 25 mM L(+)-tartaric acid
Dosages 20, 30, or 50 mg/kg
Administration Administered via p.o. twice daily
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
