    ECHEMI Editorial Reference
    Estradiol benzoate is a synthetic ester, is the first form of estrogen to be marketed.
    17beta-estradiol 3-benzoate is a benzoate ester resulting from the formal condensation of benzoic acid with the phenolic hydroxy group of 17beta-estradiol. It has a role as a xenoestrogen and an estrogen receptor agonist. It is a benzoate ester and a 17beta-hydroxy steroid. It derives from a 17beta-estradiol.|Estradiol Benzoate is a pro-drug ester of [DB00783], a naturally occurring hormone that circulates endogenously within the human body. Estradiol is the most potent form of all mammalian estrogenic steroids and acts as the major female sex hormone. As a pro-drug of estradiol, estradiol benzoate therefore has the same downstream effects within the body through binding to the Estrogen Receptor (ER) including ERα and ERβ subtypes, which are located in various tissues including in the breasts, uterus, ovaries, skin, prostate, bone, fat, and brain. [DB00783] is commonly produced with an ester side-chain as endogenous estradiol has very low oral bioavailability on its own (2-10%). First-pass metabolism by the gut and the liver quickly degrades the estradiol molecule before it gets a chance to enter systemic circulation and exert its estrogenic effects. Esterification of estradiol aims to improves absorption and bioavailability after oral administration (such as with Estradiol valerate) or to sustain release from depot intramuscular injections (such as with Estradiol Cypionate) through improved lipophilicity. Following absorption, the esters are cleaved, resulting in the release of endogenous estradiol, or 17β-estradiol. Ester pro-drugs of estradiol are therefore considered to be bioidentical forms of estrogen. Estradiol benzoate is not currently available in Canada or the US.|Estradiol Benzoate is the synthetic benzoate ester of estradiol, a steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females. As the primary, most potent estrogen hormone produced by the ovaries, estradiol binds to and activates specific nuclear receptors. This agent exhibits mild anabolic and metabolic properties, and increases blood coagulability. (NCI04)
