Lovastatin inhibits HMGCR (3-hydroxy-3-methylglutaryl coenzyme A reductase), blocking the enzyme-catalyzed transformation of 3-hydroxy-3-methylglutaryl CoA into mevalonate. The biosynthesis of cholesterol requires mevalonate as a building block and elimination of mevalonate generation subsequently interrupts cholesterol synthesis, leading to a reduction of circulating low-density lipoproteins. Lovastatin demonstrates arrest of the cell cycle at the G1 phase in bladder carcinoma T24 cells expressing activated p21ras oncoprotein - the posttranslational isoprenylation of the p21ras with mevalonate is for translocation and membrane adhesion of the protein, and blockade of this modification by Lovastatin-induced depletion of cellular mevalonate leads to suspension of cell progress. The signaling activity of epidermal growth factor (EGF) and insulin-like growth factor (IGF-I) are similarly affected by impairment of mevalonate-dependent protein prenylation. Induction of apoptosis by Lovastatin in malignant mesothelioma cells is also ascribed to the inhibition of mevalonate synthesis and posttranslational protein modifications. Lovastatin is a substrate of CYP and Mdr-1.
