|Section2= |Section3= }} 7-Keto-DHEA (also known as 7-Keto, 7-ketodehydroepiandrosterone, or 7-oxodehydroepiandrosterone)〔This compound has a number of chemical names, including: * 7-Ketodehydroepiandrosterone * 7-Oxodehydroepiandrosterone * 3β-Hydroxy-5-androstene-7,17-dione * 5-Androsten-3β-ol-7,17-dione For the acetate ester: * 3β-Acetoxyandrost-5-ene-7,17-dione * 7-Oxo-dehydroepiandrosterone acetate * 7-Oxo DHEA acetate * 3-Acetyl-7-oxo-dehydroepiandrosterone * 3-Acetyl-7-oxo DHEA * DHEA acetate-7-one * Δ5-Androstene-3β-acetoxy-7,17-dione Note: "Keto" can be substituted for "oxo" in the above names.〕 is a steroid produced by metabolism of the prohormone dehydroepiandrosterone (DHEA). 7-Keto is not directly converted to testosterone or estrogen, and has thus been investigated as a potentially more useful relative of DHEA. It is often used as the acetate ester prodrug 7-Keto-DHEA acetate. While ''in vitro'' and animal studies have suggested potential uses for 7-Keto in humans, there is currently insufficient scientific evidence to support its use as a weight-loss aid, muscle-builder, immune stimulant, or for any other clinical use. Nevertheless, 7-Keto is marketed as a dietary supplement with the implication that it may accelerate weight loss, increase metabolism, enhance memory, or prevent age-related changes. When used in a topical (skin lotion) product 7-Keto caused long-lasting changes in the body's levels of testosterone, epitestosterone, estradiol, and other steroid hormones. Researchers have raised concern that supplements may trigger positive tests for performance-enhancing drugs. The World Anti-Doping Agency lists 7-keto DHEA as a prohibited anabolic agent. ==Effects and uses== 7-Keto is unique among other derivatives of DHEA because of its oxygenated 7-position. This molecular configuration imparts different characteristics to the molecule, and research reveals that 7-Keto DHEA has multiple distinct effects in the body. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「7-Keto-DHEA」の詳細全文を読む スポンサード リンク
