About the same was observed for the statin effect on CYP2C9 activity, except that F was a strong inhibitor of this activity (IC(50) value: 4 microM). We and others, however, have demonstrated that antipsychotic drugs induce transcriptional activation of cholesterol and fatty acid biosynthesis genes controlled by the SREBP1 and SREBP2 transcription factors (11, 12). P was not affecting any of the CYP activities in the three systems studied. Introduction to Cholesterol Metabolism. D. functions as a bile acid sequestrant. Please enable it to take advantage of the complete set of features! However, up-regulation was not observed with statins, well-established cholesterol biosynthesis inhibitors, and this pointed to the presence of another mechanism other than reduced cholesterol synthesis. Effect of lipid synthesis inhibitors. The most popular agents for cholesterol reduction are the statin drugs, which are competitive inhibitors of hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase, the primary rate-limiting enzyme in the hepatic biosynthesis of cholesterol. doi: 10.1371/journal.pone.0137720.
