An overview on biological mechanisms of PPARs.
Structural features of PPARs, their gene transcription mechanisms and recent developments in the discovery of their biological functions are reviewed. Expand
Novel PPAR‐gamma Agonists Identified from a Natural Product Library: A Virtual Screening, Induced‐Fit Docking and Biological Assay Study
In this study, structure‐based virtual screening of the PPAR‐gamma ligand binding domain against a natural product library has revealed 29 potential agonists, and induced‐fit docking investigations provide a detailed understanding on the ligands’ mechanism of action. Expand
Chemistry and Pharmacology of Gynostemma pentaphyllum
In traditional Chinese medicine, Gynostemma pentaphyllum (Thunb.) Makino is a herbal drug of extreme versatility and has been extensively researched in China. The dammarane saponins isolated fromExpand
Anti-diabetic action of Punica granatum flower extract: activation of PPAR-gamma and identification of an active component.
Findings indicate that PPAR-gamma is a molecular target for PGF extract and its prominent component gallic acid, and provide a better understanding of the potential mechanism of the anti-diabetic action of PGF. Expand
Harpagoside suppresses lipopolysaccharide-induced iNOS and COX-2 expression through inhibition of NF-kappa B activation.
The results suggest that the inhibition of the expression of cyclooxygenase-2 and inducible nitric oxide by harpagoside involves suppression of NF-kappaB activation, thereby inhibiting downstream inflammation and subsequent pain events. Expand
Herbal or natural medicines as modulators of peroxisome proliferator-activated receptors and related nuclear receptors for therapy of metabolic syndrome.
The purpose of this review is to highlight the recent advances made by pharmaceutical and research organizations in identifying biologically active compounds from natural plant products capable of modulating nuclear receptors such as peroxisome proliferator-activated receptors and, to a lesser extent, liver X receptor and farnesoid X receptor.

Salacia oblonga root improves postprandial hyperlipidemia and hepatic steatosis in Zucker diabetic fatty rats: activation of PPAR-alpha.
It is demonstrated that chronic oral administration of the water extract from the root of SO to Zucker diabetic fatty (ZDF) rats, a genetic model of type 2 diabetes and obesity, lowered plasma triglyceride and total cholesterol levels, increased plasma high-density lipoprotein levels and reduced the liver contents of triglyceride, non-esterified fatty acids (NEFA) and the ratio of fatty droplets to total tissue.

Salacia oblonga improves cardiac fibrosis and inhibits postprandial hyperglycemia in obese Zucker rats.
Chronic administration of Salacia oblonga water extract markedly improved interstitial and perivascular fibrosis in the hearts of the OZR and demonstrated a strong inhibition of alpha-glucosidase activity in vitro, which is suggested to contribute to the improvement of postprandial hyperglycemia.

Salacia root, a unique Ayurvedic medicine, meets multiple targets in diabetes and obesity.
Results of bioassay-guided identification indicate that mangiferin, salacinol, kotalanol and kotalagenin 16-acetate are at least in part responsible for these multi-target regulatory activities of Salacia roots. Expand
Salacia oblonga root improves cardiac lipid metabolism in Zucker diabetic fatty rats: modulation of cardiac PPAR-alpha-mediated transcription of fatty acid metabolic genes.
It is suggested that improvement by SOE of excess cardiac lipid accumulation and increased cardiac FA oxidation in diabetes and obesity occurs by reduction of cardiac FA uptake, thereby modulating cardiac PPAR-alpha-mediated FA metabolic gene transcription. Expand
