Simvastatin is a competitive inhibitor of HMG-CoA reductase (Ki = 0.12 nM). Simvastatin reduces plasma cholesterol levels in rats and dogs when administered at doses of 1.2 and 8 mg/kg, respectively. Simvastatin suppresses TNF-induced NF-kappaB activation (IC50 = ~13 µM) and potentiates apoptosis in human myeloid...

Fluvastatin is an inhibitor of HMG-CoA reductase (Ki = 0.3 nM for the rat enzyme). It also inhibits the human cytochrome P450 (CYP) isoform CYP2C9 (IC50 = 100 nM). Fluvastatin inhibits oxidized LDL-induced ferroptosis and reverses oxidized LDL-induced decreases in glutathione peroxidase 4 (GPX4) and system Xc-...
