Equol
Equol is a metabolite of daidzein, a phytoestrogen common in the human diet and abundant in soy. Intestinal bacteria in humans can reduce daidzein to equol, and can be found in normal human urine. The clinical effectiveness of soy isoflavones may be a function of the ability to biotransform soy isoflavones to the more potent estrogenic metabolite, equol, which may enhance the actions of soy isoflavones, owing to its greater affinity for estrogen receptors, unique antiandrogenic properties, and superior antioxidant activity. However, not all individuals consuming daidzein produce equol. Only approximately one-third to one-half of the population is able to metabolize daidzein to equol. This high variability in equol production is presumably attributable to interindividual differences in the composition of the intestinal microflora, which may play an important role in the mechanisms of action of isoflavones. (PMID: 17579895, 17579894). Equol can be found in Bacteroides, Bifidobacterium, Enterococcus, Lactobacillus and Eggerthella (PMID: 20519412; PMID: 18838805).

(-)-(S)-Equol is a high affinity ligand for estrogen receptor β with a Ki of 0.73 nM. (-)-(S)-Equol is a high affinity ligand for estrogen receptor β with a Ki of 0.73 nM. (-)-(S)-Equol is a high affinity ligand for estrogen receptor β with a Ki of 0.73 nM. (±)-Equol is the racemate of equol. (±)-equol exhibits EC50s of 200 and 74 nM for human ERα and ERβ, respectively. Equol is a metabolite of the soy isoflavones, daidzin and daidzein.
2-hydroxyisoflavanone naringenin
2-hydroxyisoflavanone naringenin, also known as 2,5,7,4-tetrahydroxyisoflavanol or 2-hydroxy-2,3-dihydrogenistein, is a member of the class of compounds known as isoflavanols. Isoflavanols are polycyclic compounds containing a hydroxylated isoflavan skeleton. 2-hydroxyisoflavanone naringenin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 2-hydroxyisoflavanone naringenin can be found in a number of food items such as wild carrot, chicory, cloves, and sweet cherry, which makes 2-hydroxyisoflavanone naringenin a potential biomarker for the consumption of these food products.
2,7,4'-trihydroxyisoflavanone
2,7,4-trihydroxyisoflavanone is a member of the class of compounds known as isoflavanols. Isoflavanols are polycyclic compounds containing a hydroxylated isoflavan skeleton. 2,7,4-trihydroxyisoflavanone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 2,7,4-trihydroxyisoflavanone can be found in a number of food items such as common mushroom, loganberry, sesbania flower, and allium (onion), which makes 2,7,4-trihydroxyisoflavanone a potential biomarker for the consumption of these food products.
Demethylvestitol
Isolated from Lablab niger (hyacinth bean) and Phaseolus vulgaris (kidney bean). Demethylvestitol is found in many foods, some of which are green bean, scarlet bean, common bean, and pulses. Demethylvestitol is found in common bean. Demethylvestitol is isolated from Lablab niger (hyacinth bean) and Phaseolus vulgaris (kidney bean).
