A selective estrogen receptor modulator. | [Definition]
ChEBI: Afimoxifene is a tertiary amino compound that is tamoxifen in which the phenyl group which is in a Z- relationship to the ethyl substituent is hydroxylated at the para- position. It is the active metabolite of tamoxifen. It has a role as an antineoplastic agent, an estrogen receptor antagonist and a metabolite. It is a tertiary amino compound and a member of phenols. It is functionally related to a tamoxifen. | [Brand name]
TamoGel (Ascend Therapeutics). | [General Description]
4-Hydroxytamoxifen is a first generation, selective estrogen receptor modulator (SERM) that functions as an antagonist in breast cancer cells but can display estrogen-like activities in the uterus and bone. | [Biological Activity]
4-hydroxytamoxifen is an estrogen receptor modulator.estrogen receptor can be selectively stimulated or inhibited, providing promising therapeutic opportunities for auto-immune diseases, prostate and breast cancer, as well as depression. | [Biochem/physiol Actions]
Metabolite of the chemotherapeutic drug tamoxifen, exhibiting more potent estrogen agonist/antagonist activity than the parent drug. Also active as intra-membranous inhibitor of lipid peroxidation. | [in vitro]
previous study was conducted to evaluate the effects of tamoxifen and its active metabolite 4-hydroxytamoxifen on isolated rat cardiac myocyte mechanical function and calcium handling. results showed that myocytes treated with 4-hydroxytamoxifen had similarly to tamoxifen-treated cells to both calcium handling and contractility [1]. | [in vivo]
previous animal study compared the extent of dna adduct formation in sd rats treated with seven tamoxifen or 4-hydroxytamoxifen. results showed that the liver weights and microsomal rates were not changed by tamoxifen or 4-hydroxytamoxifen treatment. moreover, the uterine weights were significantly decreased and uterine peroxidase activity was marginally decreased in tamoxifen or 4-hydroxytamoxifen treated rats. in addition, hepatic dna adduct levels in rats treated with 4-hydroxytamoxifen did not differ from control rats. similaryly, the adduct levels in uterus dna from rats treated with tamoxifen or 4-hydroxytamoxifen were not different from those in control rats [2]. | [IC 50]
