typhaneoside and Inflammation

Non-alcoholic fatty liver disease (NAFLD) is one of the most frequent health issues. The improvement of NAFLD is related to the activation of the farnesoid X receptor (FXR). Typhaneoside (TYP) is the main component of Typha orientalis Presl, which plays a positive role in the resistance of glucose and lipid metabolism disorders. This study aims to investigate the alleviative effect and the underlying mechanism of TYP on OAPA-induced cells and high-fat-diet (HFD)-induced mice with disorders of glucose and lipid metabolism, inflammation, oxidative stress and lower thermogenesis through FXR signaling. All the serum lipid, body weight, oxidative stress and inflammatory levels of WT mice were significantly increased after HFD administration. These mice were presented with pathological injury, liver tissue attenuation, energy expenditure, insulin resistance, and impaired glucose tolerance. These above-mentioned changes in HFD-induced mice were remarkably reversed by TYP, which improved HFD-induced energy expenditure, oxidative stress, inflammation, insulin resistance, and lipid accumulation in a dose-dependent manner by activating the expression of FXR. Furthermore, using a high throughput drug screening strategy based on fluorescent reporter genes, we found that TYP functions as a natural agonist of FXR.TYP-mediated FXR activation also significantly repressed TG hyperaccumulation in mouse primary Hepatocytes (MPHs). However, these beneficial effects of TYP were not observed in FXR

Neuroinflammation is a key contributor to neuronal damage in neurodegenerative diseases. In our previous work on natural effective neuroinflammatory inhibitors, Alhagi sparsifolia Shap. (Leguminosae), a folk medicine widely distributed in Xinjiang, attracted our attention because of its significant anti-neuroinflammatory effect. Therefore, further investigation of the bioactive material basis was carried out. As a result, 33 major components were characterized and identified by chromatographic and spectral methods, respectively. Furthermore, the anti-neuroinflammatory effects of the extract and purified constituents were evaluated in LPS-induced N9 cells in vitro. The results displayed that compounds 1, 2, 3, 5, 6, 8, 11, 15, 16, 17, 22, 23, 25, 26, 28, 30, 33 could exhibit significant inhibitory activities without obvious cytotoxicities at their effective concentrations. Especially, isorhamnetin (1) (IC
