| Physical and Chemical Properties | White crystalline powder, soluble in methanol, ethanol, DMSO and other organic solvents, derived from the synthesis of daidzein, activity is stronger than daidzein. |
| In vitro study | Equol is a metabolite produced by the action of daidzein by the intestinal flora. Equol has a high affinity for the estrogen receptor (including ERalpha and ERbeta). There are two enantiomeric forms of Equol, R-equol and S-equol. S-equol has a high affinity and preferentially binds to ERbeta with a K I of 16 nM, while R-equol has a weak binding and preferentially binds to ERalpha with a K I of 50 nM. The antioxidant activity of Equol was better than that of all other isoflavones. Equol has anti-estrogenic properties. Equol was 100 times more effective than daidzein in stimulating the estrogen response. Equol in conjunction |
| In vivo study | (-)-(S)-Equol inhibits the tumor growth by 43.2% and 28.4% compared to the control on day 33, suggesting that the compound is not overtly toxic. |
