• Definition

  ChEBI: Methandrostenolone is an organic molecular entity.

• Manufacturing Process

  As described in US Patent 2,929,763, methandrostenolone may be made by a fermentation route. 2 g of sodium nitrate, 1 g of primary potassium orthophosphate, 0.5 g of magnesium sulfate heptahydrate, 0.5 g of potassium chloride, 50 g of glucose and 1 g of Difco yeast extract are dissolved in one liter of tap water, brought to pH 5 by addition of a sodium hydroxide solution and sterilized. The resulting nutrient solution is inoculated with 50 cc of a 4- day-old shaking culture of Didymella lycopersici and shaken for 48 hours at 27°C, whereby the culture becomes well developed.
  To two liters of a culture so prepared there is added under sterile conditions a solution of 500 mg of 17α-methyl-testosterone in 15 cc of acetone. Shaking is carried out for 3 days at 27°C, the mycellium then filtered off with suction, washed with water and ethyl acetate and the combined filtrates extracted with ethyl acetate. The extraction residue obtained after evaporation of the solvent is dissolved in a little acetone. On addition of ether, the 1-dehydro-17αmethyl-testosterone is obtained in compact crystals. MP 163° to 164°C.
  An alternative synthetic route is described in US Patent 2,900,398 as follows. A suspension of 30 g of 17α-methyl-testosterone and 10 g of selenium dioxide in 600 cc of tertiary amyl alcohol is treated with 60 g of magnesium powder and 6 cc of glacial acetic acid.
  The mixture is refluxed for 24 hours with good stirring in an atmosphere of nitrogen, another 10 g of selenium dioxide being added after 10 hours. After some cooling, the suspension is filtered through some Hyflo and washed thoroughly with ethyl acetate. The resulting brown solution is evaporated in vacuo and the residue dissolved in ethyl acetate.
  The ethyl acetate solution is then washed with water, dried and evaporated. To remove any selenium still present, the residue is dissolved in 200 cc of methanol and mixed with 100 g of iron powder and 2 g of active carbon. The mixture is heated for 30 minutes with stirring under reflux, then filtered with suction, washed with methanol and the solution evaporated in vacuo. The residue is then chromatographed on 900 g of aluminum oxide. The residues of the evaporated benzene and ether fractions are treated with active carbon in methanol or acetone, evaporated again, and the residue recrystallized from a mixture of acetone and ether. There are obtained 17.5 g of pure 1-dehydro17α-methyl-testosterone which melts at 163° to 164°C.
