QUICK LINKS

GSK1838705A is an ATP-competitive inhibitor of IGF-IR and IR, with Ki values of 0.7 nM and 1.1 nM, respectively, and cellular IC 50 values of 85 nM and 79 nM, respectively. GSK1838705A shows anti-proliferative effects in L-82, SUP-M2, SK-ES and MCF-7 and NPM-ALK cells with EC50 of 24 nM, 28 nM, 141 nM, 203 nM, and 24-88 nM respectively. GSK1838705A shows an accumulation of MCF-7 and NCl-H929 cells predominantly in G1 (2N) phase of the cell cycle. GSK1838705A potently inhibits NPM-ALK phosphorylation in Karpas-299 and SR-786 cells, while has modest effect on STAT3 phosphorylation.
