摘要:FTY720 is employed for the treatment of multiple sclerosis and exerts apoptotic effects on various cancers through protein phosphatase 2A (PP2A) activation. In compound 4 , the dihydroxy head group of FTY720 was modified into dihydroxy phenyl group. The cell survival in compound 4 treated colorectal and gastric cancer cells was significantly reduced as compared with control, 34.6 and 25.1%, respectively. The docking study of compound 4 showed that the aromatic head group effectively binds to PP2A.
