Lovastatin is an inactive lactone prodrug that must be chemically or enzymatically converted to its dihydroxy open-acid form in order to elicit inhibitory activity. Lovastatin in its hydroxy acid form is an exceptionally potent competitive inhibitor of liver HMG CoA reductase. Lovastatin, other than its anticholesterol property, has diverse applications in the field of osteoporosis, neuro-degeneration, rheumatoid arthritis, antifungals and also is reported to reduce proliferation of lung cancer cells, breast cancer (MCF-7), liver cancer (HepG2). Lovastatin treatments show significant dose dependent cytotoxic effect on HeLa cells with IC50 value of 160 μg/mL. Lovastatin is effective to accelerate hydroxyl radical scavenging activity (54.06%) at an IC50 of 3601 μg/mL.

Lovastatin is an inactive lactone that is hydrolyzed in the liver to an active f3-hydroxyacid form. This principal metabolite is the inhibitor of the enzyme HMG-CoA reductase. The Ki is 1 nM. Lovastatin and its β-hydroxyacid metabolite are highly bound to human plasma proteins. Lovastatin crosses the blood-brain and placental barriers. Lovastatin produces a profound reduction of apolipoprotein-B-containing lipoproteins, especially LDL cholesterol and, to a lesser extent, plasma triglycerides, and a small increase in HDL cholesterol.
