Common NameEstrone
ClassSmall Molecule
Description
Estrone, one of the major mammalian estrogens, is an aromatized C18 steroid with a 3-hydroxyl group and a 17-ketone. It is produced in vivo from androstenedione or from testosterone via estradiol. It is produced primarily in the ovaries, placenta, and in peripheral tissues (especially adipose tissue) through conversion of adrostenedione. Estrone may be further metabolized to 16-alpha-hydroxyestrone, which may be reduced to estriol by estradiol dehydrogenase.

Toxicity Profile
Route of Exposure43%
Mechanism of ToxicityEstrogens enter the cells of responsive tissues (e.g. female organs, breasts, hypothalamus, pituitary) where they interact with estrogen receptors. Hormone-bound estrogen receptors dimerize, translocate to the nucleus of cells and bind to estrogen response elements (ERE) of genes. Binding to ERE alters the transcription rate of affected genes. Estrogens increase the hepatic synthesis of sex hormone binding globulin (SHBG), thyroid-binding globulin (TBG), and other serum proteins and suppress follicle-stimulating hormone (FSH) release from the anterior pituitary.
MetabolismHepatic. Half Life: 19 hours
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesFor management of perimenopausal and postmenopausal symptoms.
Minimum Risk LevelNot Available
Health EffectsNot Available
SymptomsSymptoms of overdose include nausea and vomiting. Estrogen related side effects include nausea, breast tenderness, fluid retention and edema, headaches and/or migraines, chloasma and poor contact lens fit. Estrogen hormone deficiency is associated with breakthrough bleeding, hypomenorrhea, irritability, depression and menopausal symptoms. Withdrawal bleeds may occur in females.
