title: Chemical synthesis of 4,4'-dimethyl-7-oxygenated sterols. Inhibitors of 3-hydroxy-3-methylglutaryl reductase.
abstract: The chemical syntheses of 4,4'-dimethylcholest-5-en-3 beta-ol-7-one, 4,4'-dimethylcholest-5-ene-3 beta, 7 beta-diol and 4,4'-dimethylcholest-5-ene-3 beta, 7 alpha-diol are described. All of these compounds were found to be potent inhibitors of 3-hydroxy-3-methylglutaryl (HMG-CoA) reductase activity in cultured mouse L cells. The synthetic scheme developed in this study utilizes commercial cholesterol as the starting material and provides a simplified method for the preparation of 4,4'-dimethyl-7-oxygenated steroids.
