GSK1838705A is a potent small-molecule IGF-1R, the insulin receptor and anaplastic lymphoma kinase (ALK) inhibitor with IC50 of 2.0, 1.6 and 0.5 nM, respectively. IC50 value: 2.0/1.6/0.5 nM ( IGF-1R/InsR/ALK) Target: IGF-1R/InsR/ALK GSK1838705A prevents the in vitro proliferation of cell lines derived from solid and hematologic malignancies, including multiple myeloma and Ewing’s sarcoma, and retards the growth of human tumor xenografts in vivo. Despite the inhibitory effect of GSK1838705A on insulin receptor, minimal effects on glucose homeostasis were obtained at efficacious doses. A single oral dose of GSK1838705A at 0.1 and 0.3 mg/kg led to 35% and 65% prevention of IGF-IR phosphorylation, respectively, whereas doses ≥1 mg/kg led to complete inhibition of ligand-induced IGF-IR phosphorylation. Meanwhile, at a dose of 30 mg/kg, prevention was lasted for ?24 hours after compound injection. GSK1838705A also suppresses the anaplastic lymphoma kinase (ALK), which mediates the aberrant growth of anaplastic large-cell lymphomas, some neuroblastomas, and a subset of non–small cell lung cancers. Due to its inhibition of ALK, GSK1838705A gives rise to complete regression of ALK-dependent tumors in vivo at well-tolerated doses.
