  • Statin-Related Inhibition of Dehydroepiandrosterone Sulfate (DHEAS) Uptake by SLCO2B1 in Prostate Cancer (PC) Cells. B, Uptake of DHEAS in PC cells with 2.5 µM DHEAS and different concentrations of statins when incubated for 60 minutes. Statistical analysis was performed by comparing each condition with the DHEAS 2.5 µM and no statin state except when indicated. C, Uptake of DHEAS in PC cells before (scrambled short hairpin RNA) and after (short hairpin RNA 2B1) SLCO2B1 is knocked down when incubated with 2.5 μM DHEAS and 100 μM atorvastatin for 10 and 60 minutes. Statistical analysis was performed by comparing each condition with scrambled short hairpin RNA after 10 minutes with DHEAS except when indicated. P = .02 for the comparison between scrambled short hairpin RNA with 10 vs 60 minutes of DHEAS incubation for LNCaP and .01 for 22RV1. Other P values are indicated in the figure. Bars indicate means and error bars indicate standard deviation.

    Graph showing retention of 99mTc-RGD measured by longitudinal SPECT imaging (~30 MBq, acquired from 70-90 mins post injection under isoflurane anaesthesia). Retention was significantly higher in the simvastatin treated ischemic limb compared to the vehicle treated ischemic limb on Days 3 and 8 post ligation (n=7 (n=3 blocked), *P<0.05, **P<0.01, 1-way ANOVA with post hoc Tuckey’s test, data shown as %ID/g ± SEM).

Biological Activity

Description Simvastatin is a competitive inhibitor of HMG-CoA reductase with Ki of 0.1-0.2 nM in cell-free assays.
HMG-CoA reductase [1]
(Cell-free assay)
0.1-0.2 nM(Ki)
In vitro

Prior to use in cell assays, Simvastatin needs to be activated by NaOH in EtOH treatment. Simvastatin inhibits cholesterol synthesis in mouse L-M cell (fibroblast), rat H4II E cell (liver), and human Hep G2 cell (liver) with IC50 of 19.3 nM, 13.3 nM and 15.6 nM, respectively. [1] Simvastatin treatment leads to a dose-dependent increase in serine 473 phosphorylation of Akt within 30 minutes, with maximal phosphorylation occurring at 1.0 µM. 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 displays anti-inflammatory effects in vitro. Simvastatin (10 μM) 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. Simvastatin (10 μM) suppresses cell-mediated macrophage TNF-γ release induced via cognate interactions by ~30%. [3]

In vivo Simvastatin orally administration inhibits the conversion of radiolabeled acetate to cholesterol with IC50 of 0.2 mg/kg. [1] Simvastatin (4 mg/day) orally administration for 13 weeks to rabbits fed an atherogenci cholesterol-rich diet, returns the cholesterol-induced increases in total cholesterol, LDL-cholesterol and HDL-cholesterol to normal level. [4] Simvastatin (6 mg/kg) produces an increase in LDL receptor-dependent binding and increases the number of hepatic LDL receptors in rabbits fed a diet containing 0.25% cholesterol. [5] Simvastatin influences inflammation independent of its effect on plasma cholesterol level. In cynomolgus monkeys consumed an atherogenic diet, Simvastatin (20 mg/kg/day) induces 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.
