Simvastatin (MK 733) is a competitive inhibitor ofHMG-CoA reductasewith aK_iof 0.2 nM.

Ki: 0.2 nM (HMG-CoA reductase)^[1]

Simvastatin suppresses cholesterol synthesis in mouse L-M cell, rat H4II E cell, and human Hep G2 cell with IC₅₀s of 19.3 nM, 13.3 nM and 15.6 nM, respectively^[1].
Simvastatin causes a dose-dependent increase in serine 473 phosphorylation of Akt within 30 minutes, with maximal phosphorylation occurring at 1.0 μM^[2].
Simvastatin (1.0 μM) enhances phosphorylation of the endogenous Akt substrate endothelial nitric oxide synthase (eNOS), inhibits serum-free media undergo apoptosis and accelerates vascular structure formation^[2].
Simvastatin shows anti-inflammatory effects, reduces anti-CD3/anti-CD28 antibody-stimulated proliferation of PB-derived mononuclear cells and synovial fluid cells from rheumatoid arthritis blood, as well as IFN-γ release at 10 μM^[3].
Simvastatin (10 μM) also blocks cell-mediated macrophage TNF-γ release induced via cognate interactions by appr 30%^[3].
Simvastatin (5 μM) significantly reduces the expression of ABCA1 in astrocytes and neuroblastoma cells, the expression of apolipoprotein E in astrocytes, and increases cyclin-dependent kinase 5 and glycogen synthase kinase 3β expression in SK-N-SH cells^[7].
Simvastatin has the ability to inhibit exosome release^[10].
Simvastatin (32 and 64 μM; 24, 48, and 72 h) inhibits tumor cell growth, arrests in the G0/G1 phase^[11].
Simvastatin (32 and 64 μM; 48 h) induces apoptosis in HepG2 and Huh7 cells^[11].

Simvastatin suppresses the conversion of radiolabeled acetate to cholesterol with an IC₅₀of 0.2 mg/kg via p.o. administration^[1]. Simvastatin (4 mg/day, p.o. for 13 weeks) returns the cholesterol-induced increases in total cholesterol, LDL-cholesterol and HDL-cholesterol to normal level in rabbits fed an atherogenci cholesterol-rich diet^[4].
Simvastatin (6 mg/kg) increases LDL receptor-dependent binding and the number of hepatic LDL receptors in rabbits fed a diet containing 0.25% cholesterol^[5].
Simvastatin (20 mg/kg/day) causes a 1.3-fold less macrophage content in lesions, and 2-fold less vascular cell adhesion molecule-1, interleukin-1beta, and tissue factor expression, companied by a 2.1-fold increases in lesional smooth muscle cell and collagen content in cynomolgus monkeys fed an atherogenic diet^[6].
Simvastatin (oral gavage; 15 and 30 mg/kg; once daily; 14 d) treatment attenuats oxidative damage, TNF-a and IL-6 levels, and restores itochondrial enzyme complex activities^[12].
