(2) Method for measuring HMG-CoA reductase inhibitory activity 100 μl of rat liver microsome stored at −80 ° C. was dissolved at 0 ° C., and a cold potassium phosphate buffer solution (100 mM,
(pH 7.4) diluted with 0.7 ml, 0.8 ml of 50 mM EDTA solution (the above-mentioned potassium phosphate buffer solution) and 0.8 ml of 100 mM dithiothreyl solution (the above-mentioned potassium phosphate buffer solution).
4 ml was added and kept at 0 ° C. This microsome solution 1.
To 675 ml, 670 μl of a 25 mM NADPH solution (the above potassium phosphate buffer solution) was mixed, and the solution was added to 0.5 mM
[3 -14 C] HMG-CoA solution (3 mCi / mmol) 670
Added to μl. To 45 μl of the mixture of the microsomes and HMG-CoA, 5 μl of a potassium phosphate buffer solution of the sodium salt of the test compound was mixed, and the mixture was incubated at 37 ° C. for 30 minutes. After cooling, 10 µl of 2N hydrochloric acid was added, and the mixture was again incubated at 37 ° C for 15 minutes. This mixture 30
μl was applied to a 0.5 mm-thick silica gel thin-layer chromatography plate (Merck AG, trade name: Art 5744), developed with toluene-acetone (1: 1), and then the Rf value was 0.5.
Scrape 45-0.60 part, 10ml scintillation
Scintillation in a vial containing a cocktail
The specific radioactivity was measured with a counter. The inhibitory activity of mevinolin (sodium salt) measured by this method was 100
Table 1 shows the relative activities of the compounds of the present invention.
