Heterocyclic steroids. Steroidal pyrimidines [PDF]
Experientia, 1963 Die erste Synthese eines Steroid-Analogen, in welchem Ring A zu einem Pyrimidin umgewandelt wurde, wird beschrieben. Die wichtigste Zwischenstufe 4b wurde durch Abbau von 19-nor-Testosteron gewonnen. Kondensation von 4b mit Thioharnstoff fuhrte zu 17β-Acetoxy-2,4-diazaestr-4-en-1-on-3-thion (5).

STEROIDS AND STEROID-LIKE COMPOUNDS [PDF]
Clinics in Sports Medicine, 1999 Athletes have been searching for an "edge" in competition as long as there has been a reward for success. Anabolic-androgenic steroids have been the most popular of these ergogenic aids when winning is the only goal. The authors present a concise review of these substances, their prevalence, efficacy, adverse effects, and legality.

Current Opinion in Critical Care, 2002
Corticosteroids are considered to be essential stress hormones. They are secreted together with adrenocorticotropic hormone (ACTH) in response to the pulsatile secretion of corticotropin-releasing hormone from the paraventricular nucleus of the hypothalamus.

Primary aldosteronism is the principal disorder of zona glomerulosa and a number of subsets have been identified: unilateral adenoma; bilateral micro- or macro-nodular hyperplasia (idiopathic aldosteronism); primary hyperplasia and aldosterone-producing carcinoma either adrenal or ectopic. The diagnostic criteria for a correct differential diagnosis of

Steroid structure and steroid activity
British Journal of Dermatology, 1976The diverse biological effects associated with naturally occurring steroids are reviewed, with particular reference to the effect upon biological activity of changes in chemical structure. The motives for synthetic modification of the natural products are discussed and are illustrated by reference to the development of systemic and topical anti ...
