The second supernatant separated after centrifugation at 16,000 x g is centrifuged at 100,000 x g for 70 minutes at 4 ° C. The microsome pellets are resuspended in as little phosphate buffer A as possible (3-5 ml / liver) and homogenized in a glass-glass homogenizer. Dithiothreitol (10 mM) is added and the preparation is aliquoted, rapidly frozen in an acetone-carbonic acid ice bath and stored at -80 ° C. The specific activity of the first microsome apparatus was 0.68 nmol mevalonic acid / mg protein / minute.

The reaction mixtures are incubated at 37 ° C. Under the conditions shown, the enzyme activity increases linearly up to the limit of 300 pg microsomal protein / reaction mixture, and the linear increase lasts for 30 minutes. The typical incubation time in drug studies is 20 minutes, resulting in a conversion of the HMG-CoA substrate to mevalonic acid 64,87927 of about 12-15%. The (DL-) HMG-CoA substrate is used at 100 pM, which is twice the concentration required to satisfy the enzyme under the conditions shown. NADPH is used in excess so that its concentration is 2.7 times that required to achieve the maximum rate of the enzyme reaction.

Standardized tests to evaluate inhibitors are performed according to the following procedure. The microsomal enzyme is incubated for 15 minutes at 37 ° C in the presence of 10 NADPH. DMSO medium with or without test compound is added and the mixture is incubated for another 15 minutes at 37 ° C. Enzyme assay -14 - is started by adding / C / HMG-CoA substrate.

The reaction mixtures are centrifuged at 15 ml minutes at 2800 rpm. The supernatants are applied to glass columns with an inner diameter of 0.7 cm over poured AG 1-X8 anion exchange resin (Biorad, formate form; 2 g) and eluted with 2.0 ml of H 2 O. The first 0.5 ml of eluate is discarded, • and the next 1.5 ml is collected and both tritium and carbon-14 in 10 ml of Opti-fluoroscintil-30 lation liquid are counted. The results are calculated as the amount of mevalonic acid (nmol) formed over 20 minutes * and corrected to correspond to 100% tritium recovery. The effects of the drugs are expressed as I-values (concentration of drug that causes a 50% reduction in enzyme activity) obtained from the pooled dose-response data with a 95% confidence interval.

Conversion of lactone drugs to sodium salts is accomplished by dissolving the lactone in DMSO, adding a 10-fold molar excess of NaOH to the solution, and allowing the mixture to stand at room temperature for 15 mL to 5 minutes. The mixture is then partially neutralized (to pH 7.5-8.0) with 1N HCl and then diluted to an enzyme reaction mixture.

The selectivity of a compound that results in a greater inhibitory effect on liver tissue would be a hallmark of an inhibitor of cholesterol synthesis. Therefore, in addition to studying cholesterol synthesis inhibitors in hepatocytes, the activity of these compounds as cholesterol synthesis inhibitors is also being studied in cultured fibroblasts. f ·: a) Prepared from human skin fibroblasts: cultures 25 Human skin fibroblasts are cultured in Eagle's minimal medium (EM) containing 10% fetal bovine serum. In each experiment, trypsin is added to stock cultures to disperse the monolayer, counted, and the cells are transferred to tissue culture dishes in 35 mm diameter wells "(5 x 10 5 cells / 2.0 ml). The cultures are incubated with 5% CO 2 and 95 % in humid humidity for 18 hours at 37 ° C. Enzymes involved in cholesterol biosynthesis are activated by removing serum-containing medium, rinsing monolayers, adding * 1.0 ml EM containing 1.0% fatty acid-free bovine serum sublime, and incubating the cultures for an additional 24 hours.
