Ridaifen B (RID-B) is a tamoxifen derivative that potently inhibits breast tumor growth. RID-B was reported to show anti-proliferating activity for a variety of estrogen receptor (ER)-positive human cancer cells. Interestingly, RID-B was also reported to possess higher potency than that of tamoxifen even for some ER-negative cells, suggesting an ER-independent mechanism of action. In this study, a T7 phage display screen and subsequent binding analyses have identified Grb10 interacting GYF protein 2 (GIGYF2) as a RID-B-binding protein. Using a cell-based assay, the Akt phosphorylation level mediated by GIGYF2 was found to have decreased in the presence of RID-B.
