CAS:4-Hydroxytamoxifen is a pharmaceutical drug that is used in the treatment of breast cancer. It is an estrogen agonist, which means it binds to estrogen receptors and activates them. 4-Hydroxytamoxifen has been shown to disrupt the endocrine system by binding with estrogen receptors and preventing the hormone 17β-estradiol from binding. This leads to transcriptional changes that are observed as a decrease in the gene expression of estrogen-regulated genes. These changes are associated with antagonistic effects on human breast cancer cells. The effect of 4-hydroxytamoxifen on cell growth is dose dependent, meaning that higher doses lead to more pronounced effects.
Ecotoxicology: 4-hydroxytamoxifen has been detected in wastewater effluent, leading to its use as a biomarker for estrogenic activity in ecosystems.Forma y color:Powder
