7-keto-dhea 7-keto-dhea 7-ketodehydroepiandrosterone (7-keto-dhea,7-oxo-dhea), also known as 7-oxoprasterone, is a prohormone produced by metabolism of the prohormone dehydroepiandrosterone (dhea). 7-keto-dhea 7-keto-dhea 7-keto-dhea acetate names iupac name 3β-hydroxyandrost-5-ene-7,17-dione systematic iupac name (3as,3br,7s,9ar,9bs,11as)-9a,11a-dimethyl-2,3,3a,6,7,8,9,9a,9b,10,11,11a-dodecahydro-1h-cyclopentaphenanthrene-1,4(3bh)-dione other names 7-oxo-dhea; 7-ketodehydroepiandrosterone; 7-oxodehydroepiandrosterone; 3β-hydroxyandrost-5-ene-7,17-dione; androst-5-en-3β-ol-7,17-dione identifiers cas number 566-19-8 y1449-61-2 (acetate) y 3d model (jsmol) interactive image chebi chebi:183808 chemspider 167751 pubchem cid 193313 unii 2334ljd2e9 y84rq0xom11 (acetate) y inchi inchi=1s/c19h26o3/c1-18-7-5-12(20)9-11(18)10-15(21)17-13-3-4-16(22)19(13,2)8-6-14(17)18/h10,12-14,17,20h,3-9h2,1-2h3/t12-,13-,14-,17-,18-,19-/m0/s1key: kprgotlngibvfl-ginzomedsa-ninchi=1/c19h26o3/c1-18-7-5-12(20)9-11(18)10-15(21)17-13-3-4-16(22)19(13,2)8-6-14(17)18/h10,12-14,17,20h,3-9h2,1-2h3/t12-,13-,14-,17-,18-,19-/m0/s1key: kprgotlngibvfl-ginzomedbe smiles o=c2\c=c4/(3cc1(c(=o)cc123)c)(c)cc(o)c4 properties chemical formula c19h26o3 molar mass 302.414 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). infobox references 7-oxo-dhea is even more effective than dhea for inducing heat production (thermogenesis). because dieting is usually accompanied by reduced resting metabolic rate, obese persons may benefit from using 7-oxo-dhea when dieting due to increased metabolic rate. 7-keto-dhea is not directly converted to testosterone or estrogen, and has thus been investigated as a potentially more useful relative of dhea. 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. the fda has proposed that it be banned from use in compounded drugs. chemistry 7-keto-dhea has a number of chemical names, including: 7-ketodehydroepiandrosterone (7-keto-dhea) 7-oxodehydroepiandrosterone (7-oxo-dhea) 7-ketoprasterone 7-oxoprasterone 3β-hydroxyandrost-5-ene-7,17-dione androst-5-en-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. history 7-keto-dhea has been marketed by alternative medicine providers as a treatment of adrenal fatigue, a pseudo-scientific term with no scientific basis. regulation the fda has proposed that 7-keto-dhea be included among substances banned from use in compounded drugs.
