Biological Activity for Raloxifene hydrochloride

Raloxifene hydrochloride is a selective estrogen receptor modulator (SERM) that binds to ERα and ERβ, and tissue-dependently activates or blocks estrogen-induced transcription. Acts as an antiestrogen in breast and uterine tissue, but displays estrogen agonist activity in bone. In D12 rat hypothalamic cells, inhibits progesterone receptor induction by estrogen with an IC50 of 1 nM.
