Biochem/physiol Actions

Equilin is the Mare estrogen and is majorly used in multi-estrogen drugs for hormone replacement therapy. It is synthesized in the microsomes of mare placenta. It mediates estrogen receptor β (ERβ) expression resulting in the activation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) which favors monocytes adhesion in atherosclerosis. In vitro equilin inhibits 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1) that catalyzes the conversion of estrone to 17β-estradiol.
