Scheme 1. The mevalonate (MA) pathway and statin mechanism of action.

Scheme 1

Simvastatin inhibits the rate-limiting enzyme hydroxymethylglutaryl (HMG)-CoA reductase to prevent the conversion of HMG-CoA to mevalonate (MA). Reversal of observed statin effects with MA co-treatment indicates that HMG-CoA reductase is the likely target enzyme of the statin.
