The indole scaffold is a prominent and privileged structural motif found in numerous natural products and in a wide range of bioactive heterocycles. Starting from the simple structural framework of serotonin, the well known neurotransmitter to complex alkaloids which are used clinically as anticancer agent, mitomycin C, and the antihypertensive alkaloid reserpine, the indole moiety is considered as the active principle. Thus over the past decade, a large number of indole-containing compounds have revealed remarkable pharmacological activity and their utility as therapeutic agents have attracted considerable attention from chemists...

BACKGROUND: The Japan Society of Hepatology guidelines indicate that HCV protease inhibitor combination therapy with simeprevir (SMV), pegylated-interferon (Peg-IFN), and ribavirin (RBV) is a therapeutic option for patients who fail to respond to a direct direct-acting antiviral (DAA) containing regimen. However, treatment outcomes have room for improvement. Fluvastatin (FLV) add-on treatment in Peg-IFN and RBV combination therapy for hepatitis C-infected patients significantly improved the sustained virological response (SVR), but the add-on effect of FLV on SMV combination therapy is not well understood...

Beyond their hemostatic functions, platelets alter their inflammatory response according to the bacterial stimulus. Staphylococcus aureus is associated with exacerbated inflammation and thrombocytopenia, which is associated with poor prognosis during sepsis. Acetylsalicylic acid and statins prevent platelet aggregation and decrease the mortality rate during sepsis. Therefore, we assessed whether these two molecules could reduce in vitro platelet activation and the inflammatory response to S. aureus. Platelets were exposed to clinical strains of S...

Cardiovascular disease (CVD) is a major problem during rheumatoid arthritis which leads to morbidity and mortality in arthritic patients. So the present study emphasizes combinatorial effect of Betulinic acid, a triterpenoid and fluvastatin, an HMG CoA reductase inhibitor on atherogenesis during arthritis. Arthritis was induced by bovine type II collagen dissolved in 0.01M acetic acid at a concentration of 4mg/mL and emulsified in equal volume of incomplete Freund's adjuvant. Betulinic acid (2mg/kg) and fluvastatin (5mg/kg) alone and in combination was administered orally from day 14 to 60...

Fluvastatin, which is one of the hydroxymethylglutaryl-CoA (HMG-CoA) reductase inhibitors (statins), is primarily metabolized by CYP2C9 and to a lesser extent by CYP3A4 and CYP2C8. Predictions of drug-drug interactions (DDI) are important for the safety of combination therapies with statins, in particular drugs that are metabolized by CYP3A4. Little information is available regarding drug interactions with fluvastatin. Since CYP2C9 is a polymorphic enzyme, we investigated the effect of DDI via CYP2C9, CYP3A4, and CYP2C8 on fluvastatin pharmacokinetics by using a validated prediction method in relation to CYP2C9 variants...

Fluvastatin (FLV) belongs to the group of compounds referred to as statins, also known as 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors. Statins act as cholesterol-lowering agents and are among the most frequently prescribed drugs. They upregulate low-density lipoprotein receptors in the liver by binding to the active site of HMG-CoA reductase, which is the key enzyme in cholesterol biosynthesis. Statins have been detected as contaminants in natural waters and are susceptible to degradation upon exposure to light...

The elevated systemic levels of cytokines in rheumatoid arthritis (RA) can change the expression of metabolic enzymes and transporters. Given that statins are lipid-lowering agents frequently used in RA patients with concurrent cardiovascular diseases, the objective of the present study was to investigate the impacts of RA on the pharmacokinetics of statins of different disposition properties in rats with collagen-induced arthritis (CIA). The expression of metabolic enzymes and transporters in tissues of CIA rats were analyzed by RT-qPCR...

BACKGROUND: Statins are commonly prescribed for the secondary prevention of ischemic stroke, but there is conflicting evidence as to whether they increase the risk of intracranial hemorrhage. Lipophilic statins cross the blood-brain barrier more freely than hydrophilic statins and may therefore increase the risk of intracranial hemorrhage. OBJECTIVE: To determine whether, in older patients following ischemic stroke, receipt of lipophilic statins was associated with differences in the risk of intracranial hemorrhage...

OBJECTIVE: Statins are widely used drugs for cholesterol lowering, which were recently found to counteract the effects of aberrant fibroblast growth factor receptor (FGFR3) signaling in cell and animal models of FGFR3-related chondrodysplasia. This opened an intriguing therapeutic possibility for human dwarfing conditions caused by gain-of-function mutations in FGFR3, although the mechanism of statin action on FGFR3 remains unclear. Here, we determine the effect of statins on FGFR signaling in chondrocytes...

Organic anion-transporting polypeptide 4C1 (OATP4C1) is an organic anion transporter expressed in the basolateral membrane of the renal proximal tubules. It plays a major role in the urinary excretion of both exogenous drugs and endogenous compounds. Our previous studies have indicated the importance of OATP4C1 in pathologic and physiologic conditions; however, the majority of its pharmacologic characteristics remained unclear. Therefore, to provide essential information for clinical drug therapy decisions and drug development, we clarified drug interactions mediated by OATP4C1...

The anti-inflammatory effects of statins (HMG-CoA reductase inhibitors) within the cardiovascular system are well-established; however, their neuroinflammatory potential is unclear. It is currently unknown whether statins' neurological effects are lipid-dependent or due to pleiotropic mechanisms. Therefore, the assumption that all statin compounds will have the same effect within the central nervous system is potentially inappropriate, with no studies to date having compared all statins in a single model. Thus, the aim of this study was to compare the effects of the six statins (atorvastatin, fluvastatin, pitavastatin, pravastatin, rosuvastatin, and simvastatin) within a single in vitro model of neuroinflammation...

Advanced glycation endproduct (AGE)-induced vascular smooth muscle cell (VSMC) proliferation and reactive oxygen species (ROS) production are emerging as important mechanisms of diabetic vasculopathy, but little is known about the molecular mechanism responsible for the antioxidative effects of statins on AGEs. It has been reported that statins exert pleiotropic effects on the cardiovascular system due to decreases in AGE-induced cell proliferation, migration, and vascular inflammation. Thus, in the present study, the authors investigated the molecular mechanism by which statins decrease AGE-induced cell proliferation and VSMC migration...

BACKGROUND: Growth hormone (GH) has been linked to cardiovascular disease but the exact mechanism of this association is still unclear. We here test if the fasting levels of GH are cross-sectionally associated with carotid intima media thickness (IMT) and whether treatment with fluvastatin affects the fasting level of GH. METHODS: We examined the association between GH and IMT in 4425 individuals (aged 46-68 years) included in the baseline examination (1991-1994) of the Malmö Diet and Cancer cardiovascular cohort (MDC-CC)...

Although statin use may affect the severity of chronic gastritis and gastric cancer, no data exists about the relationship between statin therapy and risk of peptic ulcer disease (PUD) in patients. We investigated the effect of statin use and the incidence of PUD from the Taiwan National Health Insurance Research Database (NHIRD). A total of 35,194 patients records for medical claims were enrolled. We performed a population-based case-control analysis to compare the incidence of PUD in patients who were prescribed statins and that in patients who were not...

Cerebral cavernous malformations (CCMs) are common vascular anomalies that develop in the central nervous system and, more rarely, the retina. The lesions can cause headache, seizures, focal neurological deficits, and hemorrhagic stroke. Symptomatic lesions are treated according to their presentation; however, targeted pharmacological therapies that improve the outcome of CCM disease are currently lacking. We performed a high-throughput screen to identify Food and Drug Administration-approved drugs or other bioactive compounds that could effectively suppress hyperproliferation of mouse brain primary astrocytes deficient for CCM3...

BACKGROUND: Thrombospondin-1 (TSP-1) is functionally important to intimal hyperplasia (IH) development. Statin drugs have beneficial pleiotropic effects, including reduced IH; however, the effect of statins on IH in a TSP-1-independent setting is unknown. HYPOTHESIS: Statins will be less effective in attenuating IH after vascular injury in TSP-1-null (Thbs1(-/-)) mice compared with wild-type (WT) mice. MATERIALS AND METHODS: Carotid artery ligation was performed on WT and Thbs1(-/-) mice...
