Defluoro atorvastatin calcium

CAS: 433289-83-9

Defluoro atorvastatin calcium is a bulk drug that has been approved to be used as an adjunct to diet to reduce elevated cholesterol levels in adults. Defluoro atorvastatin calcium is the desfluoro-enantiomer of atorvastatin, which is a statin that inhibits the enzyme HMG-CoA reductase. This enzyme catalyzes the conversion of HMG-CoA to mevalonic acid, which is an early step in the synthesis of cholesterol. The fluoro group on defluoro atorvastatin calcium is not expected to have any significant effect on its potency or metabolic pathways and any impurities are not expected to have any therapeutic effect.
