(R)-Equol (CAS 221054-79-1)

(R)-Equol is a biologically active compound that belongs to a class of nonsteroidal compounds known as isoflavandiol, which is derived from the metabolism of soy isoflavonoids. Specifically, (R)-Equol is a stereoisomer of equol, a molecule produced by the bacterial flora in the gut during the digestion of soy products containing daidzein, an isoflavone. The (R)-Equol isomer is of particular interest due to its strong affinity for binding to estrogen receptors, particularly the beta type. This binding capability suggests its potential involvement in the modulation of estrogenic activity, which can influence various biological processes. Unlike its stereoisomer (S)-Equol, which is more commonly studied for its higher estrogenic activity, (R)-Equol is less potent but still significant due to its unique interaction with estrogen receptors. In scientific research, (R)-Equol is examined for its potential effects on hormonal balance and its role in preventing diseases related to estrogen levels. Additionally, the study of (R)-Equol helps in understanding the complex interactions within the human microbiome and its ability to metabolize dietary components into bioactive metabolites. This compound′s metabolic and binding activities make it a subject of interest in nutritional science and pharmacological studies, focusing on its potential research applications.
