生物活性
YK-4-279是EWS-FLI1与RNA helicase A (RHA)结合的有效抑制剂。体外研究
YK-4-279 eliminates cyclin D levels by blocking the interaction of EWS-FLI1 with RHA in EWS-FLI1-containing TC32 cells. YK-4-279 also specifically inhibits ESFT cell growth and induces apoptosis. YK-4-279 also inhibits ERG and ETV1 biological activity in fusion-positive prostate cancer cells, and further decreases cell motility and invasion.体内研究
In vivo, YK-4-279 (1.5 mg/dose i.p.) inhibits the growth of ESFT xenograft tumors. In mouse model, YK-4-279 selectively prevents prostate cancer growth and metastasis in fusion-positive LNCaP-luc-M6 tumors.
