MEVACOR® (lovastatin) is a cholesterol lowering agent isolated from a strain of Aspergillus terreus. After oral ingestion, lovastatin, which is an inactive lactone, is hydrolyzed to the corresponding α- hydroxyacid form. This is a principal metabolite and an inhibitor of 3-hydroxy-3-methylglutarylcoenzyme A (HMG-CoA) reductase. This enzyme catalyzes the conversion of HMG-CoA to mevalonate, which is an early and rate limiting step in the biosynthesis of cholesterol.
Lovastatin is [1S-[1α(R*),3α,7α,8α(2S*,4S*), 8aα]]-1,2,3,7, 8,8a-hexahydro-3,7-dimethyl-8-[2-(tetrahydro-4-hydroxy-6-oxo-2H-pyran-2-yl)ethyl]-1-naphthalenyl 2-methylbutanoate. The empiricalformula of lovastatin is C24H36O5 and its molecular weight is 404.55. Its structural formula is:
