Biochem/physiol Actions

Simvastatin, a synthetic analog of lovastatin, is a specific inhibitor of HMG-CoA reductase (3-hydroxy-3-methyl-glutaryl-CoA reductase.) HMG-CoA is a major therapeutic target for reduction of low density lipoprotein (LDL) cholesterol. Simvastatin may also have beneficial effects on endothelial function, smooth muscle cell function, hemostasis, vascular wall function, LDL oxidation, and inflammation. Simvastatin can be activated prior to use by treatment with NaOH in EtOH.

Simvastatin is a specific inhibitor of HMG-CoA reductase, the enzyme that catalyzes the conversion of HMG-CoA to mevalonate, an early step in cholesterol biosynthesis. It is used in the treatment of hypercholesterolemia, as it reduces levels of low-density lipoproteins and triglycerides, and raises high-density lipoprotein levels. Simvastatin is a lactone that is readily hydrolyzed in vivo to the corresponding β-hydroxyacid, and can be activated prior to use with NaOH in EtOH treatment. It is a synthetic analog of lovastatin (Cat. No. M2147).

What isProduct S6196, Simvastatin, soluble in?
According to the Merck Index, 14th ed., Entry # 8539, simvastatin is soluble in chloroform at 610 mg/mL, DMSO at 540 mg/mL, methanol at 200 mg/mL, ethanol at 160 mg/mL, 0.1 M HCl at 60 μg/mL, PEG-400 at 70 mg/mL, 0.1 M NaOH at 70 mg/mL, and water at 30 μg/mL. Please note that some of the values are given in milligrams per mL and others are in micrograms per mL.
How isProduct S6196, Simvastatin, activated?
An activation procedure from M. Sadeghi, et al., J. Immunol., 165, 2712-2718 (2000) is:1. 4 mg of simvastatin is dissolved in 100 μl of ethanol.2. Then 150 μl of 0.1 N NaOH was added to the solution and subsequently incubated at 50 °C for 2 hours.3. The pH was brought to 7.0 by HCl, and the final concentration of the stock solution was adjusted to 4 mg/ml. The stock solution was kept at 4 °C.
What is the solution stability ofProduct S6196, Simvastatin, in various solvents?
Sigma-Aldrich has not determined the solution stability of simvastatin. One publication on the subject, published by Yang, H. et al., reports that a 50 mg/mL stock solution of simvastatin in methanol was stored for one month at 4°C. Reference: Determination of Simvastatin in human plasma by liquid chromatographymass spectrometry.J. Chromatography B, 785(2), 369-375 (2003).
