Bazedoxifene (TSE-424) is a selective estrogen receptor modulator that binds to and activates ERα and ERβ with IC50 values of 26 nM and 99 nM, respectively. It also inhibits IL-6/GP130 interactions, suppresses STAT3 signaling, induces apoptosis, and reduces tumor growth, viability, and colony formation in cancer models, while being studied for effects on bone density, uterine health, and CNS vasomotor responses.
