Potent insulin receptor (IR) and insulin-like growth factor-1 receptor (IGF1R) inhibitor (IC50 values are 1.6 and 2 nM, respectively). Also inhibits anaplastic lymphoma kinase (ALK) (IC50 = 0.5 nM). Displays > 800-fold selectivity for IR, IGFR1 and ALK over a panel of 44 kinases including JNK. Blocks proliferation of cancer cell lines in vitro, and causes complete regression of ALK-dependent tumors in vivo. Orally bioavailable.
Sold for research purposes under agreement from GlaxoSmithKline.
