Xanthine Derivatives

Statin side effects are not a rare occurrence, in particular dyspeptic disorders, insomnia, headache, skin erythema, rash are often noted. All of this determines scientists to find new effective and low-toxic hypolipidemic agents. Various natural and synthetic xanthine derivatives have been recognized as therapeutically potential compounds and reported to control various diseases. Therefore, the study of new xanthine derivatives and their hypolipidemic effects, which would have a significant therapeutic effect with minimal side effects, is relevant. The aim of the study was to examine the effect of 7-β-hydroxy-γ-aryloxypropylxanthinyl-8-thioalkanic acid derivatives on lipidogram parameters in experimental laboratory rats. Materials and methods. The objects of the study were 7-β-hydroxy-γ-aryloxypropylxanthinyl-8-thioalkanic acid derivatives. The experiments were performed in white laboratory Wistar rats weighing 180–220 g. Experimental modeling of hyperlipidemia – tween model: intraperitoneal administration of tween-80 at a dose of 200 mg/100 g body weight. The test compounds were administered orally, simultaneously with tween, at a dose of 1/10 of LD50 (previously calculated by Prozorovsky express method) for 6 days. The following indicators of lipidogram were determined: total cholesterol (TC), high-density lipoprotein cholesterol (HDL cholesterol), low-density lipoprotein cholesterol (LDL cholesterol), triglycerides (TG) and atherogenic index of plasma: TC – HDL cholesterol / HDL cholesterol. The experiments were carried out with respect to Bioethical rules and norms. Results. The studies have shown data on the hypolipidemic activity of 7-β-hydroxy-γ-aryloxypropylxanthinyl-8-thioalkane acid derivatives. According to the conditional efficiency index Ʃ, which included the overall percentage of the following indicators – total cholesterol, low-density lipoprotein cholesterol and triglycerides, the leading compounds were 2439 (87.47 %), 6047 (82.30 %). The reference drug atorvastatin had a value of 82.98 %. Conclusions. The major compound was 2439 identified among all compared to the control group. The prospect of further research is a more detailed study on the ability of xanthine derivatives to exhibit hypolipidemic effects and to influence oxidative stress in various hyperlipidemic models.

1. Increased blood or plasma viscosity has been observed in almost all conditions associated with accelerated atherosclerosis. Cognizant of the enlarging body of evidence implicating increased viscosity in atherogenesis, we hypothesize that the effects of low-density lipoprotein and high-density lipoprotein on blood viscosity correlate with their association with risk of atherosclerosis. 2. Blood viscometry was performed on samples from 28 healthy, non-fasting adult volunteers using a capillary viscometer. Data were correlated with haematocrit, fibrinogen, serum viscosity, total cholesterol, high-density lipoprotein-cholesterol, triglycerides and calculated low-density lipoprotein-cholesterol. 3. Low-density lipoprotein-cholesterol was more strongly correlated with blood viscosity than was total cholesterol (r = 0.4149, P = 0.0281, compared with r = 0.2790, P = 0.1505). High-density lipoprotein-cholesterol levels were inversely associated with blood viscosity (r = −0.4018, P = 0.0341). 4. To confirm these effects, viscometry was performed on erythrocytes, suspended in saline, which had been incubated in plasma of various low-density lipoprotein/high-density lipoprotein ratios. Viscosity correlated directly with low-density lipoprotein/high-density lipoprotein ratio (n = 23, r = 0.8561, P < 0.01). 5. Low-density lipoprotein receptor occupancy data suggests that these effects on viscosity are mediated by erythrocyte aggregation. 6. These results demonstrate that the effects of low-density lipoprotein and high-density lipoprotein on blood viscosity in healthy subjects correlate with their association with risk of atherosclerosis. These effects on viscosity may play a role in atherogenesis by modulating the dwell or residence time of atherogenic particles in the vicinity of the endothelium.

Introduction: Accumulating evidence suggests that apolipoprotein B (apoB) is superior to low-density lipoprotein cholesterol (LDL-C) in prediction of cardiovascular events. Yet, an important outstanding question is whether apoB, relative to LDL, is an enhanced marker for subclinical atherosclerosis, particularly in diabetics where LDL levels may underestimate atherogenic lipid burden due to increased proportion of small, dense LDL. Hypothesis: We hypothesized that plasma apoB would be a better predictor than LDL-C of coronary artery calcification (CAC) scores in type 2 diabetics and non-type 2 diabetics. Methods: We performed cross-sectional analyses of asymptomatic Caucasians in (1) The Study of Inherited Risk of Coronary Atherosclerosis (434 men and 383 women; median age 48, non-diabetics) and (2) The Penn Diabetes Heart Study (580 men and 261 women; median age 60, type 2 diabetics). Results: Levels of apoB and LDL-C were correlated in diabetics (r=0.78, p<0.001) and non-diabetics (r=0.77, p<0.001). There was no association between LDL-C and CAC in diabetics. In non-diabetics, an association of LDL-C was lost after adjustment for total cholesterol. In contrast, after controlling for age, gender, statin therapy, and total cholesterol, levels of apoB were positively associated with CAC in diabetics [tobit regression ratio for 30 mg/dl increase in apoB 2.94 (95% CI 1.62 – 5.53), p=0.001) and had a more modest association with CAC in non-diabetics [1.67 (95% CI 1.16 – 2.32), p=0.005]. Conclusions: ApoB, but not LDL-C, predicted CAC scores, a measure of coronary atherosclerotic burden. The strength of this association was greater in diabetics than non-diabetics. Relative to LDL-C, plasma apoB levels may be particularly useful in assessing CVD risk in type 2 diabetes.

Objective: To compare serum levels of total cholesterol, triglycerides, low density lipoprotein cholesterol and high density lipoprotein cholesterol between broilers and laying hens. Materials and Methods: the present is a cross study, descriptive and analytic. Data was analyzed using simple ANOVA, the program Statgraphics Plus 5.1 was used. The study was performed at Universidad de Caldas in Manizales (Colombia). After fasting, blood from 30 broilers (Cobb 500 line) of 35-day-old and 40 laying hens (Hy-Line W-36 line) of 26-weeks-old. Serum levels of triglycerides, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol was measured by enzymatic colorimetric methods, direct method (detergent + N,Nbis (4-sulfobutyl)-m-toluidine) was used for the lipoprotein cholesterol. Results: Between broilers (Cobb 500 line) and (laying hens (Hy-line W-36 line) was significant difference in serum levels of triglycerides and in serum levels of high density lipoprotein cholesterol (P <0.05); serum levels of total cholesterol and serum levels of low density lipoprotein cholesterol, no differences were found (P> 0.05) Conclusions: Despite differences in gender, age, and production system among broilers Cobb 500 line and laying hens Hy-Line W-36, no differences were found between serum total cholesterol and low density lipoprotein cholesterol.
