Treatment with probucol, a widely used lipid-lowering agent, is associated with a significant reduction of high density lipoprotein (HDL) cholesterol levels, but with an apparently improved removal of cholesteryl esters from tissues (e.g., from tendon xanthomas). The effects of probucol (500 mg twice daily) on HDL subfraction distribution and cholesteryl ester transfer activity were tested in 12 patients with stable type II hyperlipidemia [low density lipoprotein (LDL) cholesterol greater than 180 mg/dl] after a placebo-controlled cross-over trial. Probucol significantly lowered total cholesterol (-13.8%), LDL cholesterol (-9.1%), and HDL cholesterol (-30%). By rate zonal ultracentrifugation, a marked reduction of HDL2 cholesterol (-68%) was shown, whereas changes in HDL3 were less significant (-21%). These findings were confirmed by polyacrylamide gradient gel electrophoresis, typically showing a reduction or disappearance of HDL2b particles and the prevalence of particles in the HDL3a range. ...
In this study, we evaluated the neuroprotective potential of combinatorial therapy with probucol and cilostazol to suppress cerebral ischemic injury with hypercholesterolemia. Probucol alone and cilostazol alone significantly reduced the infarct volume in ApoE KO mice fed a HFD, and the combinatorial administration of probucol and cilostazol significantly reduced infarct size with neurological deficits. In addition, cotreatment with probucol and cilostazol increased CBF due to enhancement of eNOS and adiponectin expression during ischemia. These data support the view that the combination of probucol and cilostazol prevents cerebrovascular damage in focal cerebral ischemic mice with hypercholesterolemia at least partly because of an increase of CBF via an increase of eNOS and adiponectin. This effect likely has a role in mediating the beneficial effects of such strategies in cerebrovascular disease, specifically ischemic stroke.. Hypercholesterolemia may increase the risk of stroke by ...
Self-microemulsifying drug-delivery system for improved oral bioavailability of probucol: preparation and evaluation Xianyi Sha, Juan Wu, Yanzuo Chen, Xiaoling FangKey Laboratory of Smart Drug Delivery (Fudan University), Ministry of Education and PLA, Department of Pharmaceutics, School of Pharmacy, Fudan University, Shanghai, ChinaAbstract: The objective of our investigation was to design a self-microemulsifying drug-delivery system (SMEDDS) to improve the bioavailability of probucol. SMEDDS was composed of probucol, olive oil, Lauroglycol FCC, Cremophor EL, Tween-80, and PEG-400. Droplet sizes were determined. In vitro release was investigated. Pharmacokinetics and bioavailability of probucol suspension, oil solution, and SMEDDS were evaluated and compared in rats. Plasma drug concentration was determined by high-performance liquid chromatography. After administration of probucol suspension, plasma drug concentration was very low. Relative bioavailability of SMEDDS was dramatically enhanced in an
A leading researcher at the University of New South Wales (UNSW) points out that there is little convincing evidence that dietary antioxidant supplements such as vitamin E prevent heart disease, despite claims to the contrary. Instead there has been a surprise finding, which relates to a synthetic antioxidant, the drug Probucol, which is no longer prescribed in Australia. "There has been a lot of hype which suggested that antioxidant vitamin supplements had a beneficial outcome for cardiovascular disease. There is no good scientific support for the notion that people who suffer from atherosclerosis, or who are at elevated risk of heart disease, gain benefit by supplements of vitamin E," said Professor Roland Stocker, from the Centre for Vascular Research at UNSW, who will present his research at the ISTH Congress in Sydney today. Stocker reported, "Our research is now leading towards the development of a new drug, based on Probucol. Probucol was previously used to reduce so-called "bad" ...

High-density lipoprotein (HDL) amounts inversely correlate with cardiovascular occasions thanks to the protective results on vascular wall structure and control cells, which are susceptible to oxidative modifications and lead to potential pro-atherosclerotic effects then. aspect. Results triggered by ox-HDL could end up being considerably attenuated by pretreatment with brief hairpin RNA-mediated CD36 knockdown or probucol. Data of Rabbit polyclonal to MCAM tests and the inverse correlation of ox-HDL and circulating EPC figures among individuals with coronary artery diseases (CAD) or CAD and type 2 diabetes also supported it. In the mean time, HDL separated from such individuals could significantly increase cultured EPCs caspase 3 activity, further supporting our proposal. This is definitely the most total study to day of how ox-HDL would impair EPCs function, which was involved with service of CD36-p38 MAPK-TSP-1 pathways and proved by not only the inverse relationship between ox-HDL and ...

Objective To investigate the effects of combination treatment with Probucol plus Aspirin on the prevention of steroid-induced avascular necrosis of femoral head(ANFH) in rabbits and to investigate the pathogenesis of ANFH. Methods Rabbits were divided randomly into three groups such as model group, treatment group and normal group. Before and after the experiment, serum lipid and prothrombin time (PT) were tested. In the 4th and 6th weeks of dexamethasone administration, the histopathological changes were observed with radiography, light microscopy and transmission electron microscopy. Results The incidence of osteonecrosis in the model group was 58%; the incidence of osteonecrosis in the treatment group(7%) was significantly lower than in the model group and no osteonecrosis was observed in the normal group. Under electron microscopy, osteocytes were found to be degenerative, necrotic and disappeared eventually. Conclusion Lipid metabolism disorder and hypercoagulability are risk factors for

Cholesterol-lowering drugs are known as "antihyperlipidemic agents". There are five major groups: (1) Fibric acid derivatives - Atromid-S (clofibrate) and Lopid (gemdibrozil), which work by preventing the liver from making or releasing cholesterol into the bloodstream, (2) Bile acid sequestrants - Questran (cholestryamine) and Colestid (cholestipol), which bind to bile acids and prevent their absorption, (3) Nicotinic acid - Nicolar (nicotinic acid), which decreases the secretion of VLDL thus the formation of "bad" LDL cholesterol, (4) Probucol - Lorelco (probucol), which enhances the clearance of cholesterol including LDL and HDL cholesterol, and (5) HMG-CoA reductase inhibitors - Mevacor (lovastatin), Pravastatin, and Zocor (simvastatin), which work to help lower LDL cholesterol ...
The treatment of high blood cholesterol is entering a new phase. As in the treatment of hypertension, several drugs with different modes of action are now available, with more under study, kindling debates about their relative benefits and costs. The rationale and evidence for appropriate treatment of patients is becoming clearer, with the National Cholesterol Education Program guidelines leading the way. We are learning to decide which patients to treat with drug therapy and why, and we should all by now be familiar with how to use the available drugs. This study looks at drug treatment from a societal perspective by analyzing the cost-effectiveness of lowering cholesterol in an attempt to help the physician include costs in decisions about treatment. To simplify this, the authors used an LDL-HDL index to estimate the reduction in coronary heart disease morbidity and mortality for each cholesterol-lowering agent, based on the findings from the Lipid Research Clinics Primary Prevention Trial, ...

Background: Treatments that generate T cell-mediated immunity to a patients unique neoantigens are the current holy grail of cancer immunotherapy. In particular, treatments that do not require cumbersome and individualized ex vivo processing or manufacturing processes are especially sought after. Here we report that AGI-134, a glycolipid-like small molecule, can be used for coating tumor cells with the xenoantigen Galalpha1-3Galbeta1-4GlcNAc (alpha-Gal) in situ leading to opsonization with pre-existing natural anti-alpha-Gal antibodies (in short anti-Gal), which triggers immune cascades resulting in T cell mediated anti-tumor immunity. Methods: Various immunological effects of coating tumor cells with alpha-Gal via AGI-134 in vitro were measured by flow cytometry: (1) opsonization with anti-Gal and complement, (2) antibody-dependent cell-mediated cytotoxicity (ADCC) by NK cells, and (3) phagocytosis and antigen cross-presentation by antigen presenting cells (APCs). A viability kit was used to test AGI

A study using genetically modified zebrafish to visualize early events involved in development of human atherosclerosis describes an efficient model - one that the researchers say offers many applications for testing the potential effectiveness of new antioxidant and dietary therapies.. The research, led by scientists from the University of California, San Diego School of Medicine, has been published online by the Journal of Clinical Investigation, and will appear in print in the December 1 issue of the journal.. Atherosclerosis is a process of lipid deposition and inflammation in the artery walls. Low-density lipoprotein (LDL) that carries "bad" cholesterol in blood is easily oxidized, and oxidized LDL promotes inflammatory responses by vascular cells. Inflamed atherosclerotic plaque can often rupture; this results in a blood clot, obstruction of blood flow to the heart or brain, and heart attack or stroke.. An international team of researchers led by Yury Miller, MD, PhD, of the UCSD ...

Samantha Reid (January 4, 1984 - January 17, 1999) was an American manslaughter victim, who lived in the Detroit, Michigan Metropolitan Area. She died at age 15 after being drugged surreptitiously with GHB. She, and another girl were poisoned by 3 young men who brought then cocktails, to which they had added either gamma-hydroxybutyric acid (GHB) or gamma-butyrolactone (GBL). Shortly after taking the drink, one girl stated that her face became numb and then both of the girls passed out, but the boys did not respond to this medical emergency. The drug continued its effects and soon the girls were having difficulty breathing. The boys eventually drove Samantha Reid to the hospital, but Samantha suffered respiratory arrest and stopped breathing on the way there and died eighteen hours later. The other girl was put on life-support. Had the one girl not abstained and drank a Mountain Dew instead of the cocktails, she might have also died and no one would have been the wiser. The three young men who ...

Given its mechanism of action in reducing VLDL secretion, it was reasonable to speculate that lomitapide would be effective in reducing LDL-C levels in hoFH. Indeed, a study in Watanabe heritable hyperlipidemic rabbits, which are homozygous for an LDL receptor mutation, have severe hypercholesterolemia, and thus are a natural animal model for hoFH, supported this concept. Treatment of Watanabe heritable hyperlipidemic rabbits with lomitapide markedly reduced plasma levels of LDL-C.16 A subsequent study confirmed that this effect was due to reduced VLDL secretion.17 Additional studies in LDL receptor-deficient mice confirmed that MTP inhibition was effective in reducing LDL-C in the absence of the LDL receptor.21. On the basis of these preclinical data and earlier clinical experience, a phase 2 proof-of-concept study of lomitapide in 6 patients with hoFH was performed.22 A dose-escalation regimen was used for the first time in this study, with the concept that it would allow gastrointestinal ...
