In Vitro
In vitro	OSI-906 inhibits IGF-1R autophosphorylation and activation of the downstream signaling proteins Akt, ERK1/2 and S6 kinase with IC50 of 0.028 to 0.13 μM. OSI-906 enables an intermediate conformation of the target protein through interactions with the C-helix. OSI-906 displays favorable metabolic stability in liver microsomes. OSI-906 fully inhibits both IR and IGF-1R phosphorylation at a concentration of 1 μM. OSI-906 inhibits proliferation of several tumor cell lines including non-small-cell lung cancer and colorectal cancer (CRC) tumor cell line with EC50 of 0.021 to 0.810 μM. ^[1]
Kinase Assay	Protein kinase biochemical assays
Kinase Assay	Protein kinase assays are either performed in-house by ELISA-based assay methods (IGF-1R, IR, EGFR and KDR) or at Upstate Inc. by a radiometric method with ATP at 100 µM concentration. In-house ELISA assays use poly(Glu:Tyr) as the substrate bound to the surface of 96-well assay plates and phosphorylation is detected using an antiphosphotyrosine antibody conjugated to horseradish peroxidase. The bound antibody is quantified using ABTS as the peroxidase substrate by measuring absorbance at 405 / 490 nm. All assays use purified recombinant kinase catalytic domains. Recombinant enzymes of human IGF-1R or EGFR are expressed as an NH2-terminal glutathione S-transferase fusion protein in insect cells and are purified in house. IC50 values are determined from the sigmoidal dose–response plot of percent inhibition versus log₁₀ compound concentration. A minimum of three measurements, performed in duplicate, are carried out with in-house assays unless otherwise indicated. OSI-906 at a concentration of 1 µM is profiled versus a panel of kinases using the ProfilerPro^TM Kinase Selectivity Assay Kit.

	実験の流れ	For assays of cell proliferation, cells are seeded into 96-well plates in appropriate media containing FCS 10% and incubated for 3 days in the presence of OSI-906 at various concentrations. Inhibition of cell growth is determined by luminescent quantitation of intracellular ATP content using CellTiterGlo. Data is presented as a fraction of maximal proliferation, calculated by dividing the cellular density in the presence of varying concentrations of OSI-906 by the cellular density of control cells treated with vehicle (DMSO) only.

In Vivo
In Vivo	OSI-906 inhibits tumor growth in an IGF-1R-driven xenograft mouse model, with 100% TGI and 55% regression at a dose of 75 mg/kg and 60% TGI and no regression at a dose of 25 mg/kg. OSI-906 administration induces different elimination half-lives of itself in dog, rat and mice, the elimination half-lives are 1.18 hours, 2.64 hours and 2.14 hours, respectively. OSI-906 administration at different single dose once-daily in femal Sprague-Dawley rat and femal CD-1 mouse reveal that the V_max is not dose-proportional to OSI-906 dose. OSI-906 elevates the blood glucose levels at a dose of 25 mg/kg after 12 days administration. OSI-906 administration at a single dose of 75 mg/kg in IGF-1R-driven full-length human IGF-1R (LISN) xenograft mouse model achieve maximal inhibition of IGF-1R phosphorylation (80%) between 4 and 24 hours with plasma drug concentrations of 26.6-4.77 μM. ^[1] OSI-906 administered as a single dose of at 60 mg/kg in NCI-H292 xenografts mice inhibits uptake of glucose at 2, 4, and 24 hours post-treatment in vivo. OSI-906 inhibits the growth of tumors in NCI-H292 xenograft mouse model. ^[2]
