Linsitinib (OSI-906) is a potent and novel small-molecule inhibitor inhibiting insulin receptor (IR) and IGF-1 receptor (IGF-1R) kinases with IC50 value of 75nM and 35nM, respectively1.
Studies in 3T3/hulGF-1R(LISN) cells showed that linsitinib inhibits the ligant-dependent autophosphorylation of IGF-1R and its downstream signaling pathways including pERK1/2, pAKT, p-p70S6K. Linsitinib showed anti-proliferative effects in different cancer cell lines including colorectal cells (SW620), breast tumor cells (DY4475) and mouse fibroblast cells (3T3/hulGF-1R) with EC50 of 21nM, 86nM, and 78nM, respectively1.
Linsitinib administrated orally in LISN derived xenograft model has been shown to suppress the tumor growth in a dose-dependent manner 1.

Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |

Reaction Conditions |
3 μM, 20 hours |
|
Applications |
All 6HCCcell lines showed higher IR phosphorylation than IGF-1R, suggesting the significance of IR activity in HCC. Furthermore, all 3 HCC cell lines (HepG2, Hep3B, and HuH-7) that are sensitive to OSI-906 had much higher phosphorylation levels of both IGF-1R and IR than insensitive cell lines. This suggests that sensitivity to OSI-906 associates with activation of both IGF-1R and IR in HCC cell lines. |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
