Mechanism of Action

Targets/IC₅₀/Ki	Insulin Receptor (Cell-free assay) 25 nM IGF-1R (Cell-free assay) 27 nM
In vitro	GSK1904529A is a reversible, ATP-competitive inhibitor and has enzyme-inhibitor binding values against IGF-1R and IR with K_i of 1.6 nM and 1.3 nM, respectively. This compound potently inhibits the ligand-induced phosphorylation of IGF-1R and IR at concentrations above 0.01 μM, followed by blocking downstream signaling (AKT, IRS-1, and ERK). It potently inhibits NIH-3T3/LISN, TC-71, SK-N-MC, SK-ES RD-ES cells with IC50 of 60 nM, 35 nM, 43 nM, 61 nM and 62 nM, respectively. This inhibitor also inhibits other multiple myeloma and Ewing's sarcoma cell lines including NCI-H929, MOLP-8, LP-1 and KMS-12-BM etc. It induces cell cycle arrest at the G1 phase in cell lines COLO 205, MCF-7, and NCI-H929, which are sensitive to this compound.
Kinase Assay	Kinase assays
Kinase Assay	GSK1904529A is dissolved in DMSO as stock solution at 10 mM. Baculovirus-expressed glutathione S-transferase-tagged proteins encoding the intracellular domain of IGF-1R (amino acids 957-1367) and IR (amino acids 979-1382) are used for determination of IC50. Kinases are activated by preincubating the enzyme (2.7 μM final concentration) in 50 mM HEPES (pH 7.5), 10 mM MgCl₂, 0.1mg/mL bovine serum albumin, and 2 mM ATP. This compound is diluted in DMSO and dispensed into the assay plates (100 nL/well). Kinase reactions contained (in 10 μL) 50 mM HEPES (pH 7.5), 3 mM DTT, 0.1mg/mL bovine serum albumin, 1mM CHAPS, 10 mM MgCl₂, 10 μM ATP, 500 nM substrate peptide (biotin-aminohexylAEEEEYMMMMAKKKK-NH2; QPC), and 0.5 nM activated enzyme. Reactions are stopped after 1 hour at room temperature with 33 μM EDTA. Peptide phosphorylation is measured by time-resolved fluorescence resonance energy transfer with 7 nM streptavidin Surelight allophycocyanin and 1nM europium-conjugated phosphotyrosine antibodies. Plates are read in a multilabel reader.
In vivo	GSK1904529A indicates 98% tumor growth inhibition in NIH-3T3/LISN tumor-bearing mice at a dose of 30 mg/kg (orally, twice-daily) and 75% in COLO 205 xenografts mice (once daily). Among HT29 and BxPC3 xenografts, this compound produces moderate tumor growth inhibition with no side effects at a dose of 30 mg/kg. Meanwhile, it shows minimal effects on blood glucose levels. This compound (~3.5 μM in blood) completely inhibits IGF-1R phosphorylation. It has been implicated in treatment of various IGF-1R-dependent tumors including prostate, colon, breast, pancreatic, ovarian, and sarcomas.
