| application | 2-deoxy-D-glucose is an inhibitor of glucose metabolism and has been reported to reverse lupus symptoms in mice together with metformin (M258815). 2-deoxy-D-glucose is a derivative of D-glucose. It is an antimetabolite and an important component of orthomyxovirus, paramyxovirus and herpes virus envelope. It can interfere with the synthesis of virus-specific glycoproteins and effectively inhibit the proliferation of herpes monovirus, RNA and DNA envelope virus, breast cancer cells, etc. Antiviral and anti-cancer drugs made of 2-deoxy-D-glucose have been used in clinical treatment research such as herpes monovirus, influenza, AIDS and cancer; anti-aging made of 2-deoxy-D-glucose Cosmetics and medical and health products are also on the market. Therefore, as a drug for the treatment of cancer, viral diseases and anti-aging, 2-deoxy-D-glucose has a wide range of application prospects and a huge market demand. |
| overview | 2-deoxy-D-glucose is an anti-metabolic substance of D-glucose, which has the effects of interfering with the synthesis of virus-specific glycoproteins, inhibiting herpes monovirus, RAN and DNA envelope virus, cancer cell proliferation, etc. At present, antiviral and anticancer drugs prepared from 2-deoxy-D-glucose have been clinically applied to herpes monovirus and cancer treatment, and health products and anti-aging cosmetics prepared from 2-deoxy-D-glucose have also been marketed. 2-DeoxyD-glucose has no toxic side effects, and has a wide range of applications in the fields of medical and health products, anti-aging cosmetics and life science research, with huge market potential and good development prospects. |
| preparation method | a, preparation of intermediates 1.08g of acetoglucosene is dissolved in 5mL of dichloromethane, the ice bath is cooled to 0 ℃ for 15 minutes, then the ice bath is removed, and 0.2mL of hydrogen bromide/acetic acid (HBr/HOAc) solution with a mass percentage concentration of 30% and 10mL of acetic anhydride are added in turn, the selective addition reaction was carried out by stirring at 22 ℃ for 24 hours. After the reaction, anhydrous sodium acetate was added to neutralize until pH = 7, stirring for 20 minutes. After filtration, the solution was swirled under reduced pressure at 25 ℃ and the pressure was 0.1MPa. The obtained solid was recrystallized with 10mL of solvent mixed with petroleum ether and ethyl acetate in a volume ratio of 1:4, then the white solid 2-deoxy-1, 3,4, 6-tetra-O-acetyl-D-glucose 1.30g was prepared by filtration and vacuum drying under reduced pressure with 99% yield. B, synthesis of 2-deoxy-D-glucose 1.0g of the prepared intermediate 2-deoxy-1, 3,4, 6-tetra-O-acetyl-D-glucose is added to 10mL of hydrochloric acid with a concentration of 37% for acid-catalyzed hydrolysis reaction, the reaction temperature is 75 ℃, the reaction time is 4 hours, and the reaction is cooled to room temperature after the end of the reaction, after removing acetyl groups, it is neutralized with 50% (w eight percent) sodium hydroxide solution to pH = 7, then the reaction solution is extracted twice with 10mL methanol solvent, and the extraction solution is combined and then swirled under reduced pressure. The swirled temperature is 28 ℃, and the pressure is 0.1MPa. The obtained solid is recrystallized with 10mL of solvent mixed with methanol and acetone in a volume ratio of 1:1.5, then, after filtration and vacuum drying, a white crystalline solid of 2-deoxy-D-glucose 0.41g was prepared with a yield of 81%. |
