Desoxyrhaponticin (3,5-dihydroxy-4'-methoxystilbene 3-O-beta-D-glucoside) inhibits glucose uptake in the intestine and kidney: In vitro and in vivo studies
J Pharmacol Exp Ther 2007 Jan;320(1):38-46.PMID:17038511DOI:10.1124/jpet.106.111526.
Rhubarb extracts have been reported to improve oral glucose tolerance in diabetic animals. In the present study we have investigated the antidiabetic actions of Desoxyrhaponticin, a major stilbene in rhubarb, as a glucose uptake inhibitor. Desoxyrhaponticin was demonstrated to inhibit glucose uptake in rabbit intestinal membrane vesicles as well as in rat everted gut sleeves, with IC50 values of 148.3 and 30.9 microM, respectively. Kinetics studies revealed that Desoxyrhaponticin is a competitive inhibitor of glucose uptake in both systems. Moreover, Desoxyrhaponticin could reduce glucose uptake in the intestinal membrane vesicles of both normal and diabetic rats. In addition, glucose uptake in the renal membrane vesicles of both normal and diabetic rats was reduced by Desoxyrhaponticin. Under the inhibition of Desoxyrhaponticin, uptake of glucose in both the intestinal and renal membrane vesicles of the normal rats was no different from that of the diabetic rats. The IC50 values of the uptake inhibition in the renal membrane vesicles of normal and diabetic rats were 118.8 and 115.7 microM, respectively. In a type 2 diabetic animal model in which rats have been treated with streptozotocin at the neonatal stage, postprandial hyperglycemia was significantly suppressed by oral administration of this compound (300 mg/kg b.wt.). These results suggest that Desoxyrhaponticin is an agent that is potentially effective in controlling postprandial hyperglycemia in diabetes. The in vivo antidiabetic action of this compound can be explained, in part at least, by inhibition of glucose transport in the small intestine and inhibition of glucose reabsorption in the kidney.
Inhibitory effect of Desoxyrhaponticin and rhaponticin, two natural stilbene glycosides from the Tibetan nutritional food Rheum tanguticum Maxim. ex Balf., on fatty acid synthase and human breast cancer cells
Food Funct 2014 Feb;5(2):251-6.PMID:24362821DOI:10.1039/c3fo60484e.
Fatty acid synthase (FAS) has attracted more and more attention as a potential target for cancer treatment. Natural FAS inhibitors are emerging as potential therapeutic agents to treat cancer. Rheum tanguticum Maxim. ex Balf. (rhubarb) is a traditional Chinese nutritional food and has been reported to possess a variety of biological activities, including the ability to induce the apoptosis of cancer cells. This study indicates that Desoxyrhaponticin (DC) and rhaponticin (RC), two stilbene glycosides from rhubarb, could be considered as promising FAS inhibitors. We found that both DC and RC could inhibit intracellular FAS activity and downregulate FAS expression in human breast cancer MCF-7 cells. In addition, the apoptotic effect of DC on human cancer cells was announced for the first time. Since FAS plays a key role in the biosynthesis pathway of fatty acids in cancer cells, these findings suggest that DC has potential applications in the prevention and treatment of cancer.
Computational Simulations Highlight the IL2Rα Binding Potential of Polyphenol Stilbenes from Fenugreek
Molecules 2022 Feb 11;27(4):1215.PMID:35209009DOI:10.3390/molecules27041215.
Widely used in global households, fenugreek is well known for its culinary and medicinal uses. The various reported medicinal properties of fenugreek are by virtue of the different natural phytochemicals present in it. Regarded as a promising target, interleukin 2 receptor subunit alpha (IL2Rα) has been shown to influence immune responses. In the present research, using in silico techniques, we have demonstrated the potential IL2Rα binding properties of three polyphenol stilbenes (Desoxyrhaponticin, rhaponticin, rhapontigenin) from fenugreek. As the first step, molecular docking was performed to assess the binding potential of the fenugreek phytochemicals with IL2Rα. All three phytochemicals demonstrated interactions with active site residues. To confirm the reliability of our molecular docking results, 100 ns molecular dynamics simulations studies were undertaken. As discerned by the RMSD and RMSF analyses, IL2Rα in complex with the Desoxyrhaponticin, rhaponticin, and rhapontigenin indicated stability. The RMSD analysis of the phytochemicals alone also demonstrated no significant structural changes. Based on the stable molecular interactions and comparatively slightly better MM/PBSA binding free energy, rhaponticin seems promising. Additionally, ADMET analysis performed for the stilbenes indicated that all of them obey the ADMET rules. Our computational study thus supports further in vitro IL2Rα binding studies on these stilbenes, especially rhaponticin.
[Molecular action mechanism of Desoxyrhaponticin and serum albumin characterized by spectroscopy combined with molecular modelling]
Zhongguo Zhong Yao Za Zhi 2014 Mar;39(6):1075-82.PMID:24956854doi
Objective: To study the molecular action mechanism of active constituents Desoxyrhaponticin (DES) and human serum albumin (HSA). Method: Under the simulated physiological condition, computer analog technology, fluorescent spectrometry and ultraviolet spectrum were combined to study the binding mechanism between drug and protein. Result: Molecular modeling was adopted to establish the binding model between DES and HSA, suggesting that the interaction force maintaining drug and protein is mainly the hydrophobic interaction with a hydrogen-bond interaction. The results from spectroscopy indicated that the interaction between DES and HSA is a dynamic binding process with a high intensity. The value of the binding distance (r) between DES and HSA was low, which demonstrate the occurrence of energy transfer. DES made an impact on HSA' structural domain microcell conformation, which resulted in hydrophobic changes in binding areas. According to the fluorescent phase diagram technical analysis, the changes in the DES-HSA reaction conformational pattern showed a "two-state" model. According to the obtained thermodynamic parameters for the DES-HSA interaction, the interactional force between DES and HSA was mainly a hydrophobic interaction. The fluorescence polarization proved that a non-covalent compound was generated during the interaction between DES and HSA. Conclusion: The spectrum experiment showed consistent results with the computer analog technology, which could provided certain reference for studies on the interaction between DES and HSA.
Rhaponticin contained Rheum officinale root extract improved Postmenopause symptom of Ovariectomized Rat
J Adv Pharm Technol Res 2021 Apr-Jun;12(2):175-179.PMID:34159150DOI:10.4103/japtr.JAPTR_324_20.
Postmenopausal women have decreased levels of the hormone estrogen. Reduced estrogen levels will often involve many symptoms that reduced quality of life. This research aims to analyze the effects of Rheum officinale root extract on postmenopausal model rats. To this end, thirty rats underwent ovariectomy (OVX) surgery and six rats were operated without having their ovaries removed. The OVX was confirmed by body weight-uterus weight ratio and a vaginal swab. Six groups of the rats were performed: SHAM group and negative control groups are given vehicle; the positive control was assigned tamoxifen; and the extract has been given three doses 7, 35, and 175 mg/200 g BW, respectively, for 30 days. The calcium content of bone ash was measured using atomic absorption spectrophotometer. Blood pressure was evaluated using CODA®, and the metabolites in the blood were assessed using gas chromatography-mass spectrometry (MS) and high-performance liquid chromatography. As a result, using ultra-performance liquid chromatography (UPLC)-MS, we found that the extract's major component was rhaponticin and its metabolites. The bone calcium levels increased with increasing doses of the extract. In the OVX group, the bone calcium content was decreased significantly 51.56% ± 8.9% g compared with the SHAM group 62.97% ±5.6% g, and the administration of Rheum extract could restore the calcium content of the bone to become 69.27% ± 3.8% g. From the above data, we concluded that Rheum root extracts contain astrigin, rhaponticin, rhapontigenin, and Desoxyrhaponticin. Rheum root extract could improve calcium content and lipid profiles of OVX rats by stimulation osteoblastogenesis. Rheum root extracts could control the blood pressure of OVX rats by reducing lipid profiles.
