Descripción

Application

Fulvestrant has been used:

• as an antagonist of estrogen receptor (ERα and ERβ) to reduce hepatocytes proliferation
• as an antagonist of ER for the suppression of estrogen responsive element in human breast cancer MCF-7 cells
• as anti-estrogen in breast cancer cell lines

Biochem/physiol Actions

Fulvestrant (ICI 182,780) is a selective estrogen receptor down-regulator (SERD). Fulvestrant is a high affinity estrogen receptor antagonist. IC₅₀ = 0.29 nM. Fulvestrant is the first "pure" antiestrogen with no agonistic activity both in vitro and in vivo.

Fulvestrant is a 7α-alkylsulphinyl analog of 17β-oestradiol and is structurally different compared to other selective estrogen receptor (ER) modulators (SERMs). It reduces dimerization and nuclear localization of the estrogen receptor (ER). Fulvestrant lowers the level of ER protein in human breast cancer cells. Fulvestrant is preferred for the treatment of women at their menopause having hormone-sensitive advanced breast cancer.
