Description：Simvastatin (MK 733) is a competitive inhibitor of HMG-CoA reductase with a Ki of 0.2 nM.

In Vitro：Simvastatin is an inactive drug precursor that has no drug activity itself and must be metabolized into its hydroxy acid form in the liver to function. In vitro experiments, it can be activated by sodium hydroxide (NaOH). 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].

In Vivo：Simvastatin suppresses the conversion of radiolabeled acetate to cholesterol with an IC50 of 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].
