Extra Details:: A cell-permeable binaphthol-sulfonamide compound that competitively disrupts Stat3 SH2 domain-pY peptide interaction and acts as a reversible inhibitor of Stat3 activation and Stat3-dependent gene transcription. Shown to block G-CSF stimulated pStat3 (IC50=4.1, 4.5 and 8.3uM in KG-1, Kasumi-1 and NB-4 cells, respectively), with no effect on ligand-induced pStat1 and selectively induce apoptosis of Stat3-dependent AML cells ((EC50 of 6-8uM) and growth arrest. Moderately affects Tie2 kinase activity (<50%) with minimal effect on JAK1, JAK2, Src family kinases and pERK1/2 and pAKT at 10uM.
