High levels of fats like triglycerides and cholesterol in the blood can cause cardiovascular diseases, prompting the search for safer, natural treatments. This study investigates the efficacy of Ruta chalepensis ethanol extract in lowering cholesterol levels using a rat model of hyperlipidemia induced by Triton WR-1339. Leaves and flowers of R. chalepensis were extracted with ethanol, and LC-MS analysis revealed high levels of quercetin (9.5%), 2,2-Dimethyl-3-methylidenebicyclo [2.2.1] heptane (8.1%), and other compounds, with monoterpenes being the most common class. Male Wistar rats received doses of the extract at 20 and 40 mg/kg, while fenofibrate (100 mg/kg) was the positive control. After 20 h, plasma lipid levels were significantly affected, showing a 72.1% reduction in total cholesterol for the 40 mg/kg group (p < 0.01) and a 67.6% reduction for the 20 mg/kg group (p < 0.01). High-density lipoprotein cholesterol levels decreased by 68.8% in the 40 mg/kg group (p < 0.01) and 58.6% in the 20 mg/kg group (p < 0.01). Low-density lipoprotein cholesterol saw reductions of 67.3% (p < 0.001) in the 40 mg/kg group and 60.4% (p < 0.01) in the 20 mg/kg group. Triglycerides dropped by 90.6% in the 40 mg/kg group (p < 0.001) and 86.7% in the 20 mg/kg group (p < 0.001). Overall, the results highlighted a stronger anti-hyperlipidemic effect in the 40 mg/kg group across all lipid parameters measured. The extract outperformed fenofibrate, particularly at the higher dose. These results imply that R. chalepensis extract is a promising natural alternative for managing hyperlipidemia. Full article

The present study was designed to establish the phenolic profile and explore the potential lipid-lowering effect of two Moroccan date fruit varieties (Majhoul and Bousrdoun). HPLC-DAD has been used for phenolic profiling. Lipid peroxidation was measured in terms of thiobarbituric acid-reactive substances (TBARS) by using egg yolk homogenate as lipid-rich media. The anti-hyperlipidemic effect of the methanolic extract was examined using both models Triton-WR-1339 and chronic high-fat-diet-induced hyperlipemic rats. Further, the serum lipid profile was determined. The HPLC-DAD analysis revealed the presence of seven phenolic acids and three flavonoids, of which gallic, caffeic acids and rutin were found to be the most abundant compounds. The gathered results indicate that rats treated with both varieties showed a significant decrease in serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels as well as an increase in high-density lipoprotein cholesterol levels compared with Triton and high-fat diet controls. Moreover, a significant decrease in body weight was observed in the date-treated groups when compared to the hyperlipidemic control group. A thiobarbituric acid reactive substances test showed that these extracts significantly inhibited lipid peroxidation. Bousrdoun, which showed the highest lipid-lowering effects, is the one that displayed the greatest inhibition of lipid peroxidation and contains the largest amount of caffeic, p-coumaric, gallic, vanillic acids, rutin and luteolin. Accordingly, dates could be used as a potential functional food, which may be used to prevent lipid disorders and oxidation. Full article

In the search for new potential antihyperlipidemic agents, the present study focuses on the synthesis of novel N-(benzoylphenyl)-5-substituted-1H-indole-2-carboxamides (compounds 8-12, 15, 16, 18) and investigating their antihyperlipidemic activity using Triton WR-1339-induced hyperlipidemic rats as an experimental model. Hyperlipidemia was developed by intraperitoneal injection of Triton WR-1339 (250 mg/kg body weight). The tested animals were divided into normal control (NCG), hyperlipidemic (HG), compound 8, 9, 15, 16, 18- and bezafibrate treated groups. At a dose of 15 mg/kg body weight, compounds 9, 16, 18 and bezafibrate (100 mg/kg) significantly (p < 0.0001) reduced elevated plasma triglycerides levels after 12 h compared to the hyperlipidemic control group. However, only the group treated with compounds 9, 16 and 18 showed an obviously significant (p < 0.001) reduction in plasma total cholesterol levels after 12 h compared to the hyperlipidemic control group. Moreover, high density lipoprotein-cholesterol levels were significantly (p < 0.0001) increased in all treated groups after 12 h compared to the hyperlipidemic control group, except for compounds 8 and 15 which revealed inactive. It is therefore reasonable to assume that compounds 9, 16 and 18 may have potential in the treatment of hyperlipidemia. Full article

The lipid-lowering activity of a series of novel N-(benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide derivatives has been studied in Triton WR-1339-induced hyperlipidemia in rats. The test animals were divided into four groups: control, hyperlipidemic, compound + 4% DMSO [C1: N-(2-benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide (1), C2: N-(3-benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide (2), C3: N-(4-benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide (3)]-treated and bezafibrate (BF)-treated. At a dose of 15 mg/Kg body weight, compounds 2, 3 and BF significantly reduced elevated plasma triglycerodes levels after 12 h. Moreover, high density lipoprotein-cholesterol levels were significantly increased in all treated groups after 12 h compared to the hyperlipidemic control group, except for C1 which was inactive. In sum, it may be stated that the results of the present study demonstrated new properties of some N-(benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide derivatives as potent lipid lowering agents and these beneficial activities may contribute to their cardioprotective and antiatherosclerotic role.
