Linsitinib

Description

The binding of insulin-like growth factor 1 (IGF-1) to the IGF-1 receptor (IGF-1R) promotes cell growth while inhibiting apoptotic pathways. Overexpression of IGF-1R is found in certain solid tumors and hematologic neoplasias. However, insulin receptor (InsR) signaling can compensate for IGF-1R inhibition. Linsitinib is a dual inhibitor of IGF-1R and InsR kinases (IC₅₀s = 35 and 75 nM, respectively). It also inhibits InsR-related receptor (IC₅₀ = 75 nM) but is without effect (IC₅₀ > 10 μM) against a large panel of other kinases. Linsitinib inhibits proliferation of a variety of tumor cell lines in vitro and has antitumor efficacy in an IGF-1R-driven xenograft mouse model when administered orally. A rapid, non-invasive method to predict the pharmacodynamic response to linsitinib has been reported.

The Uses of Linsitinib

Linsitinib is a small-molecule dual insulin-like growth factor-1 receptor (IGF-IR) and insulin receptor (IR) kinase inhibitor. IGF-I receptor (IGF-IR) has been implicated in the promotion of tumorigenesis, metastasis and resistance to cancer therapies and thus Linsitinib may be a useful anticancer agent.
