生物活性

製品説明 GSK1838705Aは、IC50が2.0 nMである強力なIGF-1R阻害剤であり、IRとALKに対してはそれぞれIC50が1.6 nMと0.5 nMと中程度の効力を示しますが、他のProtein Tyrosine Kinaseにはほとんど活性がありません。
in vitro GSK1838705A potently and ATP-competitively inhibits IGF-1R and IR with appKi values of 0.7 nM and 1.1 nM, respectively.In cells, this compound potently inhibits ligand-induced phosphorylation of IGF-1R and IR with IC50 of 85 nM and 79 nM, respectively. It shows the significant anti-proliferative effect in a panel of cell lines derived from solid and hematologic tumors such as L-82, SUP-M2, SK-ES and MCF-7 cells with EC50 of 24 nM, 28 nM, 141 nM and 203 nM, respectively. This chemical shows an accumulation of MCF-7 and NCl-H929 cells predominantly in G1 (2N) phase of the cell cycle. It also inhibits ALK with Ki of 0.35 nM and supresses the proliferation of nucleophosmin (NPM)-ALK fusion cells with EC50 of 24-88 nM. This compound potently inhibits NPM-ALK phosphorylation in Karpas-299 and SR-786 cells, while has modest effect on STAT3 phosphorylation.
in vivo In NIH-3T3/LISN tumor-bearing mice, oral treatment of GSK1838705A (60 mg/kg) cause tumor growth inhibition by 77%, without significant weight loss. In COLO 205 tumor-bearing mice, inhibition of tumor growth by this compound (30 mg/kg) is 80%. Besides, the antitumor efficacy of this chemical is also observed in mice bearing HT29 xenograft or BxPC3 xenograft. In mice, this compound (60 mg/kg) leads to a transient 2-fold increase in blood glucose levels by inhibiting IR signaling. It (60 mg/kg) inhibits the growth of established Karpas-299 xenografts with 93% tumor growth inhibition, with no effect on weights of the rats.
特徴 A small-molecule kinase inhibitor of IGF-1R and the insulin receptor.

キナーゼアッセイ Kinase Assays
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 determinations of IC50s by a homogeneous time-resolved fluorescence assay. A filter binding assay is used for appKi determinations using activated IGF-1R and IR kinases. Expanded kinase-selectivity profiling of this compound is carried out by screening it in the KinaseProfiler panel.
細胞アッセイ 細胞株 L-82, SUP-M2, SK-ES and MCF-7
濃度 0 to 10 μM
反応時間 72 hours
実験の流れ Cells are seeded in 96-well dishes, incubated overnight at 37 °C, and treated with DMSO or GSK1838705A for 72 hours. For the NIH-3T3/LISN proliferation assays, cells are seeded on collagen-coated 96-well tissue culture plates and allowed to adhere for 24 hours. The medium is replaced with serum-free medium and the cells are treated with this compound for 2 hour. Cells are incubated for 72 hours after addition of IGF-I (30 ng/mL). Cell proliferation is quantified using the CellTiter-Glo Luminescent Cell Viability Assay. IC50s are determined from cytotoxicity curves using a four-parameter curve fit software package (XLfit4
動物実験 動物モデル L-82, SUP-M2, SK-ES and MCF-7 cells are injected s.c. into the right flank of CD1 or SCID mice.
