개요

Equol is a nonsteroidal estrogen produced from the metabolism of the isoflavonoid phytoestrogen daidzein by human intestinal microflora. The estrogen receptor (ER) binding activity of the naturally occurring (S)-enantiomer demonstrates greater affinity toward ERβ while the (R)-enantiomer demonstrates greater affinity towards ERα. Synthesized as a racemic mixture, (±)-equol exhibits EC50 values of 200 and 74 nM for human ERα and ERβ, respectively and induces breast cancer cell proliferation in vitro at concentrations as low as 100 nM.

용도

(+/-)-Equol exhibits EC50 values of 200 and 74 nM for human ERα and ERβ, respectively and induces breast cancer cell proliferation in vitro at concentrations as low as 100 nM. It is a weak estrogenic agonist, and competitive inhibitor of 17β-estradiol at the estradiol receptor. It inhibits 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced neoplastic cell transformation by targeting the MEK/ERK/p90RSK/activator protein-1 signalling pathway. It functions as a DHT blocker.

주요 응용

(±)-Equol is a metabolite produced in vivo from the soy phytoestrogen daidzein by the action of certain gut microflora, and is a nonsteroidal estrogen of the isoflavonoid class. (±)-Equo has been reported to have estrogenic activity and affinity for estrogen receptors. (±)-Equo can exist in two enantiomeric forms, (S)-equol and (R)-equol. In binding assays, (S)-equol has a higher binding affinity for estrogen β receptors.

생물학적 활성

Metabolite of daidzein. Weak estrogenic agonist, and competitive inhibitor of 17β-estradiol at the estradiol receptor.
(R,S)-Equol is a flavonoid. Racemic mixture. This is a metabolite that is produced in vivo from soy phytoestrogen daidzein from gut microflora. (R,S)-Equol inhibits 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced neoplastic cell transformation by targeting the MEK/ERK/p90RSK/activator protein-1 signalling pathway. (R,S)-Equol shows positive effects on the incidence of prostate cancer. Functions as a DHT blocker. Preferentially activates estrogen receptor β (ERβ).
