[0177] Equol (7-hydroxy-3(4'hydroxyphenyl)-chroman), the major metabolite of the phytoestrogen daidzein, specifically binds and blocks the hormonal action of 5a~dihydrotestosterone (DHT) in vitro and in vivo. Equol can bind circulating free DHT and sequester it from the androgen receptor, thus altering growth and physiological hormone responses that are regulated by androgens. These data suggest a novel model to explain equol's biological properties. The significance of equol's ability to specifically bind and sequester DHT from the androgen receptor have important ramifications in health and disease and may indicate a broad and important usage for equol in the treatment and prevention of androgen-mediated pathologies of skin and hair. Thus, equol can specifically bind DHT and prevent DHT's biological actions in physiological and pathophysiological processes affecting skin and hair.

L'équol (7-hydroxy-3(4'hydroxyphényl)-chroman), le métabolite majeur du phyto-oestrogène daidzein, se lie de manière spécifique et bloque l'action hormonale de la 5a-dihydrotestostérone (DHT) in vitro et in vivo. L'équol peut se lier à la DHT libre circulatoire et la séquestrer depuis le récepteur androgène, ce qui modifie les réponses des hormones de croissance et physiologiques qui sont régulées par des androgènes. Ces données suggèrent un nouveau modèle afin d'expliquer les propriétés biologiques de l'équol. L'importance de la capacité de l'équol à se lier spécifiquement à la DHT et à la séquestrer depuis le récepteur androgène a des ramifications considérables sur la santé et la maladie et étend son utilisation dans le traitement et la prévention des pathologies de la peau et des cheveux ou poils induites par des androgènes. L'équol peut ainsi se lier spécifiquement à la DHT et empêcher les actions biologiques de la DHT dans des processus physiologiques et pathophysiologiques affectant la peau et les cheveux ou les poils.
