Used as an intermediate for the manufacture of steroid hormone drugs. It has anti-aging and protein assimilation effect. Main functions :1. Delay senility and keep youthful vitality; 2. 2. Enhance physical performance, improve mood and sleep, and improve memory; 3. Improve sexual function and libido; 4. Adjust the function of the immune system, improve the body immunity, 5. 6. Adjuvant treatment of disease


*  application:

In recent ten years, a large number of studies have shown that 7-Keto-dehydroepiandrosterone (7-Ketodhea) or 7-Ketodheaac has stronger physiological activity than DHEA. Especially in anti-aging, enhance immunity, improve memory boost brain function, prevent alzheimer's disease and diabetes, reduce heart disease risk, weight loss, increase bone density and muscle energy has a strong role, and in the human body metabolism not for sex hormones (including male and female sex hormones), non-toxic side effects, more effective and safe than DHEA. 7-Ketodheaac has been approved as a food supplement by the U.S. Food and Drug Administration. 7-Ketodhea is easily converted into 7-Ketodhea in the human body, so the activity of both is the same. However, 7-Ketodhea is not only used as a food supplement, but also used as an active ingredient in cosmetic products, skin diseases and other treatments.


*  The preparation of:

Using dehydroepiandrosterone or its acetate as raw materials, 7-ketone dehydroepiandrosterone or its acetate was directly synthesized by selective allyl oxidation reaction in the system of Cro3 /NHPI/ carrier /CH2Cl2 carrier at 18 ~ 40℃. The specific steps are as follows: Wet DHEA2.8g(0.01mol) and added 0.6GnHPI (0.0036mol) dissolved in 150mL dichloromethane, stirred for 10min, then added 9.0g silica gel carrier reagent (equivalent to 1g, 0.01mol chromium trioxide), stirred for 4h at room temperature. Then 9.0g of silica gel carrier reagent was added, and then 9.0g of silica gel carrier reagent was added 24 hours later until the reaction was completed (thin-layer detection)(50 hours). Filter the mixture, wash the filter cake twice with 20mL dichloromethane and recycle it. Wash the filtrate twice with saturated NaHCO3 solution, remove the water layer, add 5g active clay in the organic layer, filter it, remove dichloromethane with rotary evaporator, obtain 2.4g crude product, and then separate it by column chromatography (60g silica gel, petroleum ether: ethyl acetate: 3∶1), and 1.8 G7-Keto-DHEA purified product was obtained. Melting point (MP) : 236-238℃.
