Simvastatin Chemical Properties,Uses,Production
Lipid-lowering drugs
Simvastatin is a cholesterol-lowering drug of statin, is a synthetic derivative of Aspergillus terreus fermentation product, is used to control blood cholesterol levels and prevent cardiovascular disease.
Simvastatin belongs to methyl hydroxyl coenzyme A (HMG-COA) reductase inhibitors, inhibits synthesis of endogenous cholesterol, and is the lipid regulator. Has a role in reducing cholesterol (TC) content of serum, liver and aorta in hyperlipidemia rabbits reducing levels of very low density lipoprotein cholesterol (VLDL-C) and low-density lipoprotein cholesterol (LDL-C).
Indications
1. Hyperlipidemia:
(1) For patients with primary hypercholesterolemia, heterozygous familial hypercholesterolemia or mixed hypercholesterolemia, when diet and other non-drug treatment is not ideal, Simvastatin can be used to reduce the increased total cholesterol, LDL cholesterol, apolipoprotein B and triglycerides. And Simvastatin increases high-density lipoprotein cholesterol, thereby reducing the LDL/HDL and total cholesterol/HDL ratio.
(2) For patients with homozygous familial hypercholesterolemia, when diet and non-diet is not ideal, Simvastatin can be used to reduce elevated total cholesterol, LDL cholesterol and apolipoprotein B.
2. Coronary heart disease:
Coronary heart disease, Simvastatin can be used to:
(1) reduce the risk of death.
(2) reduce risk of coronary heart disease death and nonfatal myocardial infarction.
(3) reduce risk of stroke and transient ischemic.
(4) reduce risk of myocardial revascularization (coronary artery bypass grafting and percutaneous coronary balloon angioplasty).
(5) delay the progression of atherosclerosis in the arteries, including the all-new lesions and the occurrence of full clogging.
The above information is edited by the chemicalbook of Liu Yujie.
Chemical properties
White crystalline powder, odorless. Soluble in ethanol, acetone or acetonitrile, difficult soluble in ether, practically insoluble in water. Melting point is 135~138 ℃.
Uses
1. HMG-CoA reductase inhibitors, can reduce the concentration of serum total cholesterol level, inhibit synthesis of cholesterol. For treatment of primary hypercholesterolemia with cholesterol levels greater than 7.8mmol/L which is invalid or not tolerated in other treatments.

Uses
anti-hyperlipoproteinemic, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor
Uses

Uses
Simvastatin is semi-synthetic, slightly more hydrophobic, analogue of lovastatin. Like lovastatin, simvastatin is a specific inhibitor of HMG-CoA reductase and is used therapeutically to reduce LDL cholesterol. More recently, the statins have become important biochemical probes in cell biology. Their involvement in many events can be correlated to their primary mode of action, however, the mechanism of action of many other effects is less apparent.
Uses
Simvastatin is a synthetic derivative of a fermentation product of Aspergillus terreus. A competitive inhibitor of HMG-CoA reductase. A synthetic analog of Lovastatin. Antilipemic. Simvastatin, the dr ug, is sold under the trade name Zocor.

Definition
ChEBI: A carbobicyclic compound that is lovastatin in which the 2-methylbutyrate ester moiety has been replaced by a 2,2-dimethylbutyrate ester group. It is used as a cholesterol-lowering and anti-cardiovascular disease drug.
Manufacturing Process
A suspension of Lovastatin (350 g, 0.865 mmol), phenylboronic acid (110.8 g,
0.909 mmol) and toluene (1.75 L) was heated under a nitrogen atmosphere
at 100-105°C for 55 min. The water was separated from the reaction mixture.
The solution was cooled and 1.39 L of toluene was removed by vacuum
distillation at 40-50°C. The concentrated solution was treated with hexanes
(3.15 L) at 40-50°C. The resulting suspension was cooled to 0-5C for 2 hours
and the product was filtered and washed with hexanes (350 mL). The product
was dried at 35-40°C under vacuum to provide 427.9 g (37%) of lovastatin
phenylboronate at >99% purity by HPLC.
A 2 L 3-necked flask was charged with pyrrolidine (56 mL, 0.67 mol) and dry
THF (453 g) under a nitrogen atmosphere. n-Butyl lithium (419 mL, 1.6 M
hexane solution, 0.67 mol) was added dropwise at -20°C over a period of 1
hour. The solution was maintained at this temperature for 30 min and then
cooled to -55°C. A solution of lovastatin phenylboronate (101.7 g, 0.20 mol)
in 274.7 g of THF was cooled to -50°C and then added to the cold lithium
pyrrolidide solution at a rate such that the internal temperature was between
-50°-55°C during the addition. The mixture was held at this temperature for 4
hours and then methyl iodide (116.4 g, 0.82 mol) was added at a
temperature below -55°C. The reaction was stirred for 13 hours at -20°C and
then quenched with 500 mL of 2 M HCl at a temperature below 0°C. After
warming to 20°C, the layers were separated and the aqueous layer was
extracted with ethyl acetate. The combined organic layers were washed with
5% NaHSO3 solution and deionized water. The solution was filtered through a
Celite pad and concentrated to yield 102.8 g (98.4%) of crude Simvastatin
phenylboronate at >95% purity by HPLC. A portion of the above material
(50.0 g) was charged into a nitrogen purged flask with acetonitrile (100 mL).
The suspension was heated at 110°C for 3 hours and then cooled to - 10°C for 1 hour. The product was filtered and washed with 25 mL of acetonitrile and
dried under vacuum to provide 43.7 g of Simvastatin phenylboronate at >99%
purity by HPLC.
A suspension of simvastatin phenylboronate (30.0 g) and 1,3-propanediol
(450 mL) was heated at 105-107°C at 0.2 mm Hg. After 1 hour, 182 mL of
distillate was collected and the reaction was cooled to 20-25°C. Deionized
water (270 mL) was added and toluene (3 times 75 mL) was used to extract
the mixture. The combined toluene layers were washed with water (60 mL).
The organic solution was heated at reflux for 1 hour and water was
azeotropically removed. The solution was concentrated to a final volume of 24
mL under vacuum at 48-50°C. To the concentrated solution was added
hexanes (215 mL) over 10 min. The resulting slurry was cooled to 0-5°C and
filtered. The crude Simvastatin was washed at 0-5°C with hexanes and dried
under vacuum to yield 21.0 g (88%) of Simvastatin.

Therapeutic Function
Antihyperlipidemic
General Description
Simvastatin, 2,2-dimethyl butanoic acid,1,2,3,7,8,8a-hexahydro-3,7-dimethyl-8-[2-(tetrahydro-4-hydroxy-6-oxo-2-pyran-2-yl)ethyl]-1-naphthalenyl ester(Zocor), is an analog of lovastatin. These two drugs havemany similar properties. Both drugs, in the prodrug form,reach the liver unchanged after oral administration, wherethey undergo extensive metabolism to several open-ring hydroxyacids, including the active -hydroxy acids. They arealso highly bound to plasma proteins. These actions makethe bioavailability of simvastatin rather poor but better thanthat of lovastatin, which has been estimated to be 5%.
Biological Activity
HMG-CoA reductase inhibitor; decreases levels of low density lipoprotein. Has multiple biological effects including bone formation stimulation, inhibition of smooth muscle cell proliferation and migration, and anticancer and anti-inflammatory activity.
Biochem/physiol Actions
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).

Metabolism
Simvastatin is absorbed from the gastrointestinal tract
and must be hydrolysed to its active β-hydroxyacid form.
Other active metabolites have been detected and several
inactive metabolites are also formed. Simvastatin is a
substrate for the cytochrome P450 isoenzyme CYP3A4
and undergoes extensive first-pass metabolism in the
liver, its primary site of action. Less than 5% of an oral
dose has been reported to reach the circulation as active
metabolites.
Simvastatin is mainly excreted in the faeces via the bile
as metabolites. About 10-15% is recovered in the urine,
mainly in inactive forms.
storage
