Common Name | 2-Hydroxyestradiol |
---|
Description | 2-Hydroxyestradiol (2-OHE2), also known as estra-1,3,5(10)-triene-2,3,17beta-triol, is an endogenous steroid, catechol estrogen. 2-Hydroxyestradiol belongs to the class of organic compounds known as estrogens and derivatives. These are steroids with a structure containing a 3-hydroxylated estrane. Thus, 2-hydroxyestradiol is considered to be a steroid molecule. It is a metabolite of estradiol, as well as a positional isomer of estriol. Transformation of estradiol to 2-hydroxyestradiol is a major metabolic pathway of estradiol in the liver. 2-Hydroxyestradiol is generated from estradiol via several cytochrome P450 enzymes. Specifically, CYP1A2 and CYP3A4 are the major enzymes catalyzing the 2-hydroxylation of estradiol. Conversion of estradiol into 2-hydroxyestradiol has been detected in the liver, uterus, breast, kidney, brain, and pituitary gland, as well as the placenta. 2-Hydroxyestradiol binds, with a low affinity, to estrogen receptors. 2-Hydroxyestradiol has approximately 7% and 11% of the affinity of estradiol at the estrogen receptors (ERs) ERalpha and ERbeta, respectively (PMID: 9048584 ). 2-Hydroxyestradiol is a catechol estrogen and in this regard bears some structural resemblance to the catecholamines dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline) (PMID: 447670 ). In accordance, 2-hydroxyestradiol has been found to interact with catecholamine systems. The steroid is known to compete with catecholamines for binding to catechol O-methyltransferase and tyrosine hydroxylase and to competitively inhibit these enzymes (PMID: 447670 ). Inactivity of COMT blocks inactivation of catechol hormones and catecholamine neurotransmitters. 2-Hydroxyestradiol is also reported to inhibit angiongensis and tumor cell growth (PMID: 9472688 ). |
