Ewing’s sarcoma is characterized by the formation of an oncogenic fusion protein, EWS-<wbr></wbr>FLI1, which binds to RNA helicase central to disease. YK-<wbr></wbr>4-<wbr></wbr>279 binds to EWS-<wbr></wbr>FLI1 (K<sub>d</sub> = 9.48 μM), blocking the interaction of EWS-<wbr></wbr>FLI1 and RNA helicase and driving apoptosis in Ewing’s sarcoma family tumors. Through these effects, YK-<wbr></wbr>4-<wbr></wbr>279 reduces the growth of Ewing’s sarcoma orthotopic xenografts. Importantly, it is effective in Ewing’s sarcoma cells, both <em>in vitro</em> and <em>in vivo</em>, that are chemotherapy-<wbr></wbr>resistant. YK-<wbr></wbr>4-<wbr></wbr>279 also binds the ETS transcription factors ERG and ETV1 (K<sub>d</sub> = 11.7 and 17.4, respectively), which form fusion proteins that contribute to some types of prostate cancer. (+)-<wbr></wbr>YK-<wbr></wbr>4-<wbr></wbr>279 is a highly purified enantiomer of YK-<wbr></wbr>4-<wbr></wbr>279. Its properties have not been characterized.
