Structural characterization of the binding interactions of various endogenous estrogen metabolites with human estrogen receptor α and β subtypes: a molecular modeling study. [PDF]

open access: yesPLoS ONE, 2013
In the present study, we used the molecular docking approach to study the binding interactions of various derivatives of 17β-estradiol (E2) with human estrogen receptor (ER) α and β. First, we determined the suitability of the molecular docking method to

Circulating Estradiol Regulates Brain-Derived Estradiol via Actions at GnRH Receptors to Impact Memory in Ovariectomized Rats [PDF]

open access: yeseneuro, 2016
AbstractSystemic estradiol treatment enhances hippocampus-dependent memory in ovariectomized rats. Although these enhancements are traditionally thought to be due to circulating estradiol, recent data suggest these changes are brought on by hippocampus-derived estradiol, the synthesis of which depends on gonadotropin-releasing hormone (GnRH) activity ...

Dose-response effects of estrogenic mycotoxins (zearalenone, alpha- and beta-zearalenol) on motility, hyperactivation and the acrosome reaction of stallion sperm

open access: yesReproductive Biology and Endocrinology, 2011
Background The aim of this study was to investigate the in vitro effects of the Fusarium fungus-derived mycotoxin, zearalenone and its derivatives alpha-zearalenol and beta-zearalenol on motility parameters and the acrosome reaction of stallion sperm ...

Retention behaviour of some estradiol derivatives on alumina in normal phase chromatography [PDF]

open access: yesJournal of the Serbian Chemical Society, 2003
The retention constants of variously substituted estradiol derivatives were measured as a function of the composition of various binary mobile phases in order to study the relationship between chemical structure and retention behaviour in TLC on alumina.

Design and Synthesis of Two Bicyclo[3.3.1]nonane-steroid Derivatives

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2020
This study describes the preparation of two bicyclo[3.3.3]nonane-steroid derivatives from either estradiol or estrone using some reactions such as etherification, addition, nucleophilic substitution and cyclization.

GC-MS/MS Determination of Steroid Hormones in Urine Using Solid-Phase Derivatization as an Alternative to Conventional Methods

open access: yesMolecules, 2022
Solid-phase analytical derivatization (SPAD) is a promising hybrid sample preparation technique combining the clean-up and preconcentration of the sample in a single step. In this work, a novel SPAD method based on the preparation of trimethylsilyl (TMS)

LCAT facilitates transacylation of 17β-estradiol in the presence of HDL3 subfraction

open access: yesJournal of Lipid Research, 2002
It has been shown that estrogens need to be metabolized to their hydrophobic estrogen ester derivatives to act as antioxidants in lipoproteins. Data suggest that 17β-estradiol (E2) becomes esterified in LCAT-induced reactions and the esters are ...

Circulating estradiol and its biologically active metabolites in endometriosis and in relation to pain symptoms

open access: yesFrontiers in Endocrinology, 2023
ObjectivesEndometriosis (EM) is an estrogen-dominant inflammatory disease linked to infertility that affects women of reproductive age. EM lesions respond to hormonal signals that regulate uterine tissue growth and trigger inflammation and pain.

Novel Locally Active Estrogens Accelerate Cutaneous Wound Healing-Part 2

open access: yesScientific Reports, 2017
Estrogen deprivation is associated with delayed healing, while estrogen replacement therapy (ERT) accelerates acute wound healing and protects against development of chronic wounds.
