Photo-DHEA—A functional photoreactive dehydroepiandrosterone (DHEA) analog
Steroids, 2011The steroid hormone dehydroepiandrosterone (DHEA) has beneficial effects on vascular function, survival of neurons, and fatty acid metabolism. However, a specific receptor for DHEA has not been identified to date. Here, we describe the synthesis of a photoreactive DHEA derivative (Photo-DHEA).

Neuroactive neurosteroids: dehydroepiandrosterone (DHEA) and DHEA sulphate
Acta Paediatrica, 1999Dehydroepiandrosterone (DHEA) and its sulphate ester (DHEAS) are neuroactive and are both imported into the brain from the circulation and produced in the nervous system. These neurosteroids have neurotrophic and excitatiory effets, and further study is needed to delineate their physiological and pathological functions.

Biotransformation of DHEA into 7α,15α-diOH-DHEA
20173β,7α,15α-Trihydroxy-5-androsten-17-one (7α,15α-diOH-DHEA) is a key intermediate of the novel oral contraceptive "Yasmin" (widely used in birth control pills and postmenopausal hormone replacement therapy pills; the active ingredient is drospirenone).

Clinical Journal of Sport Medicine, 2002
Dehydroepiandrosterone (DHEA), a 19-carbon steroid, is situated along the steroid metabolic pathway. It is the most abundant circulating hormone in the body and can be converted to either androgens or estrogens. It is readily conjugated to its sulphate ester DHEAS, and they are designated as DHEA(S) here when used together. Its secretion reaches a peak

Current Opinion in Obstetrics and Gynecology, 1996
Dehydroepiandrosterone (DHEA) and DHEA-sulfate (DHEAS) represent the major androgens secreted by the adrenal gland. Various functions including metabolic, immune, and cognitive effects have been attributed to this steroid and are reviewed here. Since the levels of DHEA correlate with general good health, and aging is associated with a decline in the ...

Lack of Hepatic Conversion of Dehydroepiandrosterone Sulfate (DHEAS) to DHEA
Endocrine Research, 2004DHEA and its sulfate ester DHEAS are the most abundant steroids in the human circulation. Only desulfated DHEA is biologically active and can be converted downstream toward sex steroids. The current concept is that DHEAS serves as the hydrophilic storage pool for DHEA regeneration and that DHEA and DHEAS are interconverted freely via hydroxysteroid ...

Dehydroepiandrosterone (DHEA) and aging
Archives of Gerontology and Geriatrics, 1997Dehydroepiandrosterone sulfate (DHEAS) is the most abundant circulating steroid hormone in humans and can readily be converted to its parent steroid DHEA by tissue sulfatases. Yet, a biologic function for these steroids has not been defined. The link between DHEA and aging has been raised by: (1) its well documented age-related decline, and (2) a ...

Annals of Pharmacotherapy, 2000
OBJECTIVE: To inform clinicians and investigators of the potential for severe mania in conjunction with the use of prasterone (DHEA; dehydroepiandrosterone). CASE SUMMARY: A 31-year-old Hispanic man was admitted on a 72-hour observation period from a neighboring hospital after threatening to kill himself, family members, and a friend.

Alternative medicine review : a journal of clinical therapeutic, 2001
Dehydroepiandrosterone (DHEA) is a steroid hormone secreted primarily by the adrenal glands and to a lesser extent by the brain, skin, testes, and ovaries. It is the most abundant circulating steroid in humans and can be converted into other hormones, including estrogen and testosterone. It has been characterized as a pleiotropic "buffer hormone," with
