Simvastatin, also known as Zocor, is a drug used to control cholesterol levels. It is a hypolipidemic agent, used to lower the levels of lipids. It is derived from the fermentation of Aspergillus terreus, a fungus which can be used to make important organic compounds. Cholesterol biosynthesis was researched at Merck by Jesse Huff, a biochemist, and his colleagues in the early 1950s. Carl Hoffman, Karl Folkers, and some colleagues at Merck isolated mevalonic acid from a yeast extract in 1956. They confirmed that this acid can be used in cholesterol biosynthesis. In Sankyo, Japan, Akira Endo was able to isolate Compactin from Penicillum citrinium, a fungus, in 1976. Carl Hoffman was able to isolate lovastatin from Asperigillus terreus in 1979. From lovastatin, the scientists at Merck were able to synthetically derive Simvastatin.
