Description and Uses

7-Ketodehydroepiandrosterone (7-Keto-dehydroepiandrosterone; 7-keto-DHEA), chemically known under 3-acetyl-7-oxo-dehydroepiandrosterone, is a naturally occurring metabolite of the steroid hormone dehydroepiandrosterone (DHEA) and is marketed as such an anti-obesity dietary supplement. The synthesis of 7-keto-DHEA begins with an irreversible hydroxylation of DHEA in the position C7 by cytochrome P450 7B1 (CYP7B1) under the formation of 7 α-hydroxy-dehydroepiandrosterone (7 α-OH-DHEA). β-hydroxysteroid dehydrogenase type 1 (11 β-HSD 1) then catalyzes the interconversion of 7 α-OH-DHEA and 7 β-hydroxy-dehydroepiandrosterone (7 β-OH-DHEA) through a 7-keto-DHEA intermediary. DHEA is a "parent hormone" produced by glands near the kidneys. However, unlike DHEA, 7-keto-DHEA is not converted to steroid hormones such as androgen and estrogen. Taking 7-keto-DHEA by mouth or applying it to the skin does not increase the level of steroid hormones in the blood. People take 7-keto-DHEA for obesity, muscle strength, anxiety, depression, and other conditions. However, there is no good scientific evidence to support these uses[1].

7-Keto Dehydro Epiandrosterone-d6 is the isotope labelled analog of 7-Keto Dehydro Epiandrosterone (K187700); a metabolite of Dehydroepiandrosterone (DHEA) (D229585) which is the major secretory steroidal product of the adrenal gland.
