Description:

2,3,5,4'-Tetrahydroxyldiphenylethylene-2-O-glucoside(TSG) has potential to the prevention and treatment of Alzheimer's diseases, it not only prevents over-expression of α-synuclein at an early stage, but also reverses the increased expression of α-synuclein and inhibits the aggregation at the late stage of Tg mice. TSG suppresses PDGF-BB-induced PASMCs proliferation is associated with an inhibition of AKT / GSK3β signaling pathways. TGS, emodin and physcion also have the lipid regulation activity to an overall synergy.

Targets:

Akt | GSK-3 | P450 (e.g. CYP17) | HMG-CoA Reductase | LDL

In vitro:

Hepatoxicity of major constituents and extractions of Radix Polygoni Multiflori and Radix Polygoni Multiflori Praeparata.[Pubmed: 21840387]

Radix Polygoni Multiflori (RPM) and Radix Polygoni Multiflori Praeparata (RPMP) were traditionally widely used as Chinese herbal medicine. However, liver adverse reactions caused by RPM or RPMP were frequently reported all around the world recent years. The aim of this study was to study the cytotoxicities of RPM, RPMP and their major constituents on human liver cell L-02 simultaneously.
METHODS AND RESULTS:
Multi-assays, including MTT assay, neutral red uptake (NRU) assay, LDH leakage percentage and liver enzyme secretion (AST, ALT and ALP) were used. Cytotoxicities of major chemical constituents of RPM, 2, 3, 5, 4'-tetrahydroxy-stilbene-2-O-β-D-glucoside (2,3,5,4'-Tetrahydroxyl diphenylethylene-2-O-glucoside，TSG), physcion and emodin, were tested. The cytotoxicities of water, 50% ethanol and 95% ethanol extractions of RPM and RPMP were tested. HPLC-DAD analysis was carried to reveal the content change of TSG, physcion and emodin after the processing procedure. The TD(50) of TSG, physcion and emodin in MTT assay were >10,000 μM, 2853.61 μM and 520.37 μM. In the NRU assay, the TD(50) of TSG, physcion and emodin were much smaller (1401.53 μM, 1140.00 μM, and 3.80 μM). Emodin induced much severe liver enzyme secretion than TSG and physcion. Cell proliferation and LDH leakage rate showed no difference between RPM and RPMP extractions, but ALP, AST and ALT secretions in RPMP extractions were significant lower than that of PMR groups. Water extractions of RPM and RPMP were less toxic than any other solvent in most of the assays. Positive correlation was found between the TSG/emodin ratio and MTT survival rate. The emodin/physcion ratio also showed positive correlation with the LDH leakage percentage. CONCLUSIONS: In conclusion, Radix Polygonum multiflorum and Radix Polygonum multiflorum Praeparata were not liver injure inducing in our in vitro assays. However, the processing produce of RPM could reduce its effect on both cell proliferation and enzyme secretion of liver cell. Judging from cell proliferation, integrity of cell membrane and enzyme secretion, three major chemical constituents of RPM: TSG, physcion and emodin showed no, moderate and severe cytotoxicity against human liver cell line L-02 respectively. Chemical constituents-cytotoxicity relationship investigation revealed that TSG and physcion probably had attenuating effect to emodin. The attenuating mechanisms were still under investigation.

Tetrahydroxystilbene glucoside antagonizes age-related α-synuclein overexpression in the hippocampus of APP transgenic mouse model of Alzheimer's disease.[Pubmed: 23160059]

To investigate the mRNA and protein alterations of α-synuclein in the brain of Alzheimer's disease-like mouse model at the different ages, and to evaluate the effects of 2,3,5,4'-tetrahydroxy stilbene-2-O-β-D-glucoside ( 2,3,5,4'-Tetrahydroxyl diphenylethylene-2-O-glucoside,TSG) on α-synuclein expression.
METHODS AND RESULTS:
TSG (120 or 240 μmol kg(-1)d(-1)) was intragastrically administered to APPV717I transgenic (Tg) mice at 4- or 10-month-old for 6 months. mRNA expression of α-synuclein increased in hippocampus in 4 month to 16 month old Tg mice compared with age-matched control. α-synuclein protein expression in hippocampus also increased in 4 month to 16 month old Tg mice significantly. Significant down-regulation of α-synuclein mRNA and protein expression in hippocampus was found after treatment of TSG for 6 months in both 10- and 16-month-old Tg mice. Production of dimer and tetramer of α-synuclein protein in Tg mice was inhibited after treatment with TSG.
CONCLUSIONS:
The expression and aggregation of α-synuclein was age-dependently increased in Tg mice. TSG not only prevents over-expression of α-synuclein at an early stage, but also reverses the increased expression of α-synuclein and inhibits the aggregation at the late stage of Tg mice. TSG may have potential to the prevention and treatment of Alzheimer's diseases.
