10β,17β-Dihydroxyestra-1,4-dien-3-one (DHED) is an orally active, centrally selective estrogen and a biosynthetic prodrug of estradiol which was discovered by Prokai and colleagues.[2][1][3] Upon systemic administration, regardless of route of administration, DHED has been found to selectively and rapidly convert into estradiol in the brain, whereas no such conversion occurs in the rest of the body.[2][1][3] Moreover, DHED itself possesses no estrogenic activity, requiring transformation into estradiol for its estrogenicity.[2][1][3] As such, the drug shows selective estrogenic effects in the brain (e.g., alleviation of hot flashes, neuroprotection) that are said to be identical to those of estradiol, whereas it does not produce estrogenic effects elsewhere in the body.[2][1][3] DHED has been proposed as a possible novel estrogenic treatment for neurological and psychiatric conditions associated with hypoestrogenism (e.g., menopausal hot flashes, depression, cognitive decline, Alzheimer's disease, and stroke) which uniquely lacks potentially detrimental estrogenic side effects in the periphery.[2][1][3]
