Equol is an isoflavan produced by intestinal bacteria in response to soy isoflavone intake in human. It shows a wide range of activities including antioxidant activity, anti-inflammation activity and anticancer activity. It is reported that Equol specifically binds to 5α-DHT and has a modest affinity for recombinant estrogen receptor ERβ, which may be responsible for most of Equol’s biological properties. [1]


In vitro: In vitro studies were conducted to measure both the binding affinity of Equol for 5alpha-dihydrotestosterone (5alpha-DHT) and the effects of Equol treatment in human prostate cancer (LNCap) cells. It was found that Equol bound to 5alpha-DHT with maximum and half maxim concentrations of 100 nM and 4.8 nM, respectively. In addition, Equol significantly offset the increases in PSA levels from LNCap cells. [1]


In vivo: An in vivo study was performed to investigate effects of equol on rat prostate weight and circulating levels of sex steroid hormones. 1.0 mg/kg of Equol was injected to Long-Evans rats fed with a low isoflavone diet for 25 days. Findings from this study suggested that Equol significantly decreased rat prostate weights and down-regulated serum levels of 5alpha-DHT. However, this agent did not alter levels of LH, testosterone and estradiol. [1]


Clinical trials: A clinical study on hypercholesterolemic patients demonstrated that, after 4 weeks’ dietary intervention with a soy isoflavone-containing food, brachial artery-mediated vasodilatation in equol-producers was notably higher when compared with that in equol-nonproducers. Similar differential effects between equol-producers and nonproducers were aslo reported in arterial stiffness from a study on postmenopausal women taking tibolone. [2]
