Linsitinib 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. Linsitinib enables an intermediate conformation of the target protein through interactions with the C-helix. Linsitinib displays favorable metabolic stability in liver microsomes. Linsitinib fully inhibits both IR and IGF-1R phosphorylation at a concentration of 1 μM. Linsitinib 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].

Transient hyperglycemia accompanied by ephemeral hyperinsulinemia induced by IR and IGF1R inhibition with OSI-906. C57BL/6J mice are subjected to a 16-hour fast and OSI-906 (45 mg/kg) or a vehicle (Solutol HS-15) is administered orally 1 hour before injection with either saline, 10 units of insulin, or 1 mg/kg of IGF-1 via the inferior vena cava. The liver and epididymal fat are collected 70 and 120 seconds after injection, respectively.

OSI-906 inhibits p-IGF1R and IGF1R signaling factors in breast cancer cell-lines. 3 × 105 ER-positive MCF7 and ER-negative are plated per well of a 6-well plate and cultured for 24 h and subsequently treated with the OSI-906 (0.1, 0.4 and 1.6 μM) and/or SKI-II (4 μM) for 24 h. Protein lysates are collected and 20 μg of protein is used for immunoblot analysis to measure changes to IGF1R signaling and SphK1 steady-state protein expression levels.

HCC-1806 breast cancer cells are plated per well of a 6-well plate and cultured for 24 h and subsequently treated with OSI-906 (0.1, 0.4 and 1.6 μM) and/or SKI-II (4 μM) for 24 h. Protein lysates are collected and 20 μg of protein is used for immunoblot analysis to measure changes to IGF1R signaling and SphK1 steady-state protein expression levels.

Expression of Sema4D and PlexinB1 in various oral squamous cell carcinoma cell lines following the addition of IGF-I. Notably, the addition of IGF-I resulted in increased expression of Sema4D, particularly in HSC-2 and SAS cells. This increase was suppressed when IGF-I was administered in the presence of inhibitors targeting its receptor or downstream signaling pathways. No changes in PlexinB1 expression were observed following the addition of IGF-I.

Protocole
Protein kinase assays are either performed in-house by ELISA-based assay methods (IGF-1R, IR, EGFR and KDR) or 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. Linsitinib at a concentration of 1 µM is profiled versus a panel of kinases using the ProfilerProTM Kinase Selectivity Assay Kit.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
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 Linsitinib 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 Linsitinib by the cellular density of control cells treated with vehicle (DMSO) only.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Cells are harvested from cell culture flasks during exponential cell growth, washed twice with sterile PBS to a suitable concentration before subcutaneous implantation on the right flank of female nu/nu CD-1 mice. Tumors are established to 200±50 mm3 in size before randomization into treatment groups of eight mice each for efficacy studies. Linsitinib or vehicle is administered orally as indicated. The %TGI values indicated are the median %TGI over the entire dosing period. TGI of at lease 505 is considered significant. Growth delay is calculated as T-C shere T and C are the times in days for mean tumor size in the treated (T) and control (C) groups to reach 400% of the initial tumor volume. Cures are excluded from this calculation.
