      A cell-permeable dihydroindolone compound that disrupts the Ewing's sarcoma oncogenic transcription factor, EWS-FLI1, complex assembly by competing against RHA (RNA helicase A) binding to EWS-FLI1 (KD = 9.48 µM) and inhibits EWS-FLI1-dependent transcription activity (by 76% and 88% in 18 h with 3 and 10 µM YK-4-279, respectively) in COS7-based reporter assays without affecting NF-κB-mediated transcription even at concentrations as high as 10 µM. Shown to exhibit apoptosis-inducing and antiproliferative activity toward ESFT (Ewing's sarcoma family tumor) cells both in cultures in vitro (IC50 between 0.5 and 8.0 µM) and in mice in vivo (Average tumor growth retardation >50% on day 14; Three 1.5 mg i.p. doses/mouse/day), while displaying little or much reduced activity toward non-EWS-FLI1 cancer cells or nontransformed cells (IC50 ≥25 µM).
