OBJECTIVES : To investigate the effect of lovastatin therapy and withdrawal on paraoxonase 1 (PON1) and arylesterase (ARE) activities, and low-density lipoprotein cholesterol (LDL-C) susceptibility to oxidation in people with type 2 diabetic nephropathy (T2DN). DESIGN AND METHODS : Lovastatin (20mg/day) was administered to 30 people with T2DN for 90days and then withdrawn for 30days. PON1 and...
Lovastatin is a potent hypercholesterolemic drug used for lowering blood cholesterol. Lovastatin acts by competitively inhibiting the enzyme, 3-hydroxy-3-methylglutaryl coenzyme A reductase involved in the biosynthesis of cholesterol. Commercially lovastatin is produced by a variety of filamentous fungi including Penicillium species, Monascus ruber and Aspergillus terreus as a secondary metabol...
INTRODUCTION We aimed to evaluate the high-sensitivity C-reactive protein (HS-CRP) level changes at the beginning and after withdrawal of lovastatin therapy in patients with diabetic nephropathy. MATERIALS AND METHODS Thirty male patients with type 2 diabetes mellitus and diabetic nephropathy were enrolled in the study. Lovastatin, 20 mg/d, was administered for 90 days. Afterwards, Lovastatin...
Lovastatin is an anti-cholesterol lactone drug indicated for the treatment of hyperlipidemia and to reduce the risk of coronary heart disease. It is converted to the β-hydroxy acid form (lovastatin acid) in vivo, which is the major pharmacologically active metabolite. Here, we describe the development and validation of an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS...
BACKGROUND Lovastatin has a unique ability to bind Leukocyte Function Antigen-1 (LFA-1), an integrin necessary for the full expression of inflammatory cytokines induced by the low molecular weight form of the extracellular matrix glycosaminoglycan hyaluronan (LMW HA). We hypothesized that lovastatin could inhibit LMW HA inflammatory signals via interaction with LFA-1, and attenuate bleomycin in...
Ability of two strains of Aspergillus terreus (ATCC 74135 and ATCC 20542) for production of lovastatin in solid state fermentation (SSF) using rice straw (RS) and oil palm frond (OPF) was investigated. Results showed that RS is a better substrate for production of lovastatin in SSF. Maximum production of lovastatin has been obtained using A. terreus ATCC 74135 and RS as substrate without additi...
OBJECTIVE Organic anion transporting polypeptide 1B1 (OATP1B1, encoded by SLCO1B1 gene) is a hepatic uptake transporter, and its genetic variability is associated with pharmacokinetics and muscle toxicity risk of simvastatin. We examined the possible effects of variations in the SLCO1B1 gene on the pharmacokinetics of lovastatin in a prospective genotype panel study. PARTICIPANTS AND METHODS ...
Statins have pleiotropic properties which are involved in inhibiting the thrombogenic response. In this study, the effects of lovastatin on two phospholipids, phosphatidylcholine and sphingomyelin, were studied in cultured endothelial cells in the presence of an oxysterol, 27-hydroxycholesterol. After the cells were cultured with 50 nM of lovastatin for 60 h, lovastatin was found to decrease th...
The mechanism by which competitive inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase decrease serum cholesterol is incompletely understood. The few available data in humans suggest that chronic administration of the competitive inhibitor, lovastatin, decreases serum cholesterol with little or no change in total body sterol synthesis. To further define the effect of lovasta...
The goals of this work were to establish a reproducible and effective model of apoptosis in a cell line derived from advanced prostate cancer and to study the role of the caspase family of proteases in mediating apoptosis in this system. The study involved the use of the prostate cancer cell line LNCaP. Apoptosis was induced using the hydroxymethyl glutaryl CoA reductase inhibitor, lovastatin, ...
