生化／生理作用
4-Hydroxyestrone is an endogenous estrogen metabolite, which exhibits a strong neuroprotective effect against oxidative damage. It also provides effective protection against kanic acid-induced hippocampal oxidative damage in rats when compared to 17β-estradiol. 4-Hydroxyestrone regulates the angiogenic process during corpus luteum formation. It might be involved in an increased risk of cancer. 4-Hydroxyestrone is found in the early and mid-luteal phases.

Glucuronidation, mediated by UDP-glucuronosyltransferases (UGTs), affects the actions and disposition of diverse endo- and xenobiotics. In the case of catecholestrogens (CEs), glucuronidation is likely to block their oxidation to quinone estrogens that are the putative mediators of CEs' actions as

Estrogen replacement therapy has been correlated with an increased risk of developing breast or endometrial cancer. 4-Hydroxyequilenin (4-OHEN) is a catechol metabolite of equilenin which is a minor component of the estrogen replacement formulation marketed under the name of Premarin

Endogenous estrogen metabolism may play an important role in the pathogenesis of hormone-related cancers, most notably breast cancer. Despite the importance of estrogen metabolism, little is known about estrogen metabolite profiles during different phases of the menstrual cycle. This study

Estrogen replacement therapy has been correlated with an increased risk of developing hormone-dependent cancers. 4-Hydroxyequilenin (4-OHEN) is a catechol metabolite of equilenin and equilin which are components of the estrogen replacement formulation marketed under the name of Premarin (Wyeth-Ayerst).
