Biological Activity

OSI-906 (Linsitinib) is an orally small-molecule inhibitor of IGF-1R with potential antineoplastic activity. IGF-1R has been viewed as an important therapeutic target due to its involvement in the growth and proliferation in a variety of human cancers, including adrenocortical carcinoma (ACC), ovarian and non-small cell lung cancers. A major challenge in the development of IGF-1R inhibitors is to avoid blocking the closely related insulin receptor that regulates glucose levels in the blood. OSI-906 (Linsitinib) selectively inhibits IGF-1R, which may result in the inhibition of tumor cell proliferation and the induction of tumor cell apoptosis. Overexpressed in a variety of human cancers, IGFR-1 stimulates cell proliferation, enables oncogenic transformation, and suppresses apoptosis. OSI-906 slowed the growth of IGF-1R-dependent tumors, and it also reduced proliferation and/or survival of a broad panel of tumor cell lines.

Customer Product Validations & Biological Datas

Method TUNEL assay
Cell Lines GEO cells
Concentrations 50~1000 nM
Incubation Time 48 h
Results Both MK-0646 and OSI-906 treated GEO xenografts had statistically significant increase in apoptosis (p<0.05) as compared with the control tumors
Cell Experiment
Cell lines NSCLC(H292, H358 and H1703) and CRC(Colo205, HT-29 and RKO) tumor cell lines
Preparation method Cell proliferation assay. cells were 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 was determined by luminescent quantitation of intracellular ATP content using CellTiterGlo (Promega, Madision , WI, USA). Data were presented as a fraction of maximal proliferation, caculated 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.
Concentrations 0~10 μM
Incubation time 72 h
Animal Experiment
Animal models LISN tumor xenograft model in mice
Formulation 25mM tartaric acid
Dosages 25mg/kg or 75mg/kg daily for 12 days
Administration orally

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km

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.
