Background:

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 manner¹.
