Product Description
Fulvestrant is a pure antiestrogen that emerged from a systematic medicinal chemistry strategy of modification of long-chain alkyl substitutes in the 7a-position of estradiol. Fulvestrant has no uterotrophic effects on the immature or ovariectomized rat and blocks the agonistic effects of estradiol and tamoxifen in a dose-dependent manner. In in vivo and in vitro breast cancer models, fulvestrant has anticancer activity at least as good as tamoxifen and is superior to tamoxifen in some models.
