Biochem/physiol Actions
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

Free radical generation by metabolic redox cycling between catechol estrogens and their quinones and subsequent hydroxyl radical damage to DNA have been proposed to mediate estrogen-induced renal carcinogenesis in the hamster. In this study the content of 8-hydroxy-2'-deoxy-guanosine (8-OHdG), a

Estrogens, including the natural hormones estrone (E(1)) and estradiol (E(2)), are thought to be involved in tumor induction. Catechol estrogen quinones (CEQ) derived from 4-hydroxyestrone (4-OHE(1)) and 4-hydroxyestradiol (4-OHE(2)) react with DNA and form depurinating N7Gua and N3Ade adducts that

Reaction of lysine with estrone 3,4-o-quinone gave a complex mixture of products. Six compounds were isolated and identified using spectroscopic techniques. Among the reaction products isolated were 4-hydroxyestrone (2), 3-aminoisoestrone (3), 3-(N-pentyl-5-amino)-isoestrone (4), 1-lysylestrone 3,4-o-iminoquinone (5), and two dimeric products

As part of an ongoing investigation of the role of metabolic activation of estrogens in the genesis of cancers such as estrogen-induced renal tumors in hamsters, we have 1) determined steroid-17 beta-oxidoreductase activity of microsomes and cytosol prepared from hamster
