Enclomiphene Usage And Synthesis
Description
Enclomiphene is a synthetic and nonsteroidal antiestrogen. It is the more potent isomer and the one responsible for its ovulation-inducing actions. The half-life of enclomiphene is relatively short, so serum concentrations rise and fall quickly during and after treatment. Antiestrogens represent the first-line treatment strategy in WHO class-2 anovulatory infertility.
Uses
trans-Clomiphene is a Clomiphene (C587025) stereoisomer, a synthetic estrogen agonist-antagonist. Gonad-stimulating principle. Treatment for infertility.
Definition
ChEBI: Clomiphene is a tertiary amine. It has a role as an estrogen antagonist and an estrogen receptor modulator. It derives from a hydride of a stilbene.
Preparation
CONDENSATION OF 4-HYDROXYBENZOPHENONE WITH 2-(DIETHYLAMINO)ETHYL CHLORIDE FOLLOWED BY TREATMENT WITH BENZYL MAGNESIUM CHLORIDE AND DEHYDRATION TO GIVE 2-(P-(1,2-DIPHENYLVINYL)PHENOXY)TRIETHYLAMINE WHICH IS CHLORINATED AND TREATED WITH CITRIC ACID /CITRATE/
Biological Activity
Enclomiphene is the trans-isomer of clomiphene citrate (CC). It has a higher rate of clearance and is less active than the cis-isomer, cis-clomiphene. Clomiphene citrate has been evaluated for antineoplastic activity against breast cancer.
Mode of action
Enclomiphene is a non-steroidal estrogen receptor antagonist that promotes gonadotropin-dependent testosterone secretion by the testes. The main mechanism of its action is thought to be its antagonistic effects on the hypothalamic-pituitary axis and stimulation of GnRH secretion.
