Hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase is the rate-limiting enzyme in the cholesterol biosynthetic pathway and the target of the “statin” class of cholesterol-lowering drugs.1 Lovastatin is an HMG-CoA reductase inhibitor that was initially isolated from Aspergillus terreus.2 Marketed as Mevinolin™, Mevacor™, and under several other trade names, Lovastatin was the first HMG-CoA reductase inhibitor to be used in the treatment of hypercholesterolemia. It is a competitive inhibitor of HMG-CoA reductase with a Ki value of 0.6 nM for the open ring, hydroxy acid form of the molecule.3 During a three week study in dogs, a dose of 8 mg/kg per day resulted in a 29% reduction in plasma cholesterol.3 Lovastatin also suppresses TNF-induced NF-κB activation (IC50 ~ 15 µM), which potentiates apoptosis in human myeloid leukemia cells and thus, maybe useful in treating cancer.4
