Because of its purported effect in gout, its effects were tested in hyperuricemic mice models induced by yeast extract paste or potassium oxonate, as well as its capacity to scavenge free radicals in vitro. Hyperuricemia was induced in mice by yeast extract paste or potassium oxonate. KD was given orally for 14 days at 200, 400 and 800 mg/kg/day, with Allopurinol 10 mg/kg/day as positive control. Serum uric acid (UA), and liver xanthine oxidase activity (XO) were measured. Scavenging activity of KD on 1, 1-diphenyl-2-picrylhydrazyl radicals (DPP•), nitric oxide (•NO), superoxide (O2•-), efficiency against lipid peroxidation, and XO inhibition were determined in vitro. KD inhibited liver XO activity and reduced serum uric acid in hyperuricemic mice. KD also showed noticeable antioxidant activity, scavenging free radicals (DPP•, •NO and O2•-). It was effe...

The polyphenol is main compounds contained in ASMq preparation responsible for anticancer effect of ASMq. In this study,Real-time quantitative Polymerase Chain Reaction (RT-PCR) assay, MTT assay and flow cytometry were used to investigate the effect of polyphenol of ASMq on cell viability and the potential of the phenolic rich extracts of ASMq to induce apoptosis in human cervical cancer cells SiHa and its effects on telomerase activity were investigated. Cellular morphological change was observed by phase contrast microscopy. The MTT cell viability data revealed that treatment with phenolic rich extracts at 75 ~ 175 μg/ml significantly inhibited the viability and proliferation of cells, and these effects occurred in a concentration-dependent manner and time dependent manner (P < 0.01). The phenolic rich extracts can induce apoptosis of SiHa cells, can increase the apoptosis rate in a concentration-dependent manner and time dependent manner (P < 0.01). Growth inhibition and apoptosis induction by phenolic rich extracts treatment on SiHa cells was associated with down-regulation of anti-apoptotic Bcl-2 expression and telomerase (P < 0.05) and Survivin expression. In addition, phenolic rich extracts exerted a dose-dependent induction of FHIT expression. These results suggest that phenolic rich extracts may have anti-tumor effects in human cervical cancer through cytotoxicity, apoptosis-inducing properties and telomerase activity.

In the present study, in vivo hepatoprotective effect of C. glandulosum root extract (CGRE) was evaluated using two experimental models, carbon tetrachloride (CCl4)- and galactosamine (GalN)-induced acute hepatotoxicity in mice. Pretreatment with CGRE (800 mg/kg/day, p.o.) for seven days significantly reduced the impact of CCl4 toxicity (10 mL/kg, i.p.) on the serum markers of liver damage, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP). Protective effect was reconfirmed against GalN-induced injury (800 mg/kg b.w., i.p.) and elevated serum enzymatic levels were significantly (p<0.05)and dose dependently restored towards normalization by the extracts. Furthermore, considering the well-known implication of free radicals in tissue injury, in vitro antioxidant properties of the extract were determined with a view to suggest the possible mechanism of activity. The extract showed noticeable antioxidant activity, comparable with standard antioxidants, through its ability to scavenge several free radicals (DPPH, O(2)(-), NO()) and efficiency against lipid peroxidation. Therefore, presented results suggest that CGRE is potent hepatoprotective agent that could protect liver against the acute injury and this ability might be attributed to its antioxidant potential.

All of the isolated xanthones were evaluated for their antibacterial activity against bacterial reference strains, two Gram-positive (Staphylococcus aureus ATTC 25923, Bacillus subtillis ATCC 6633) and two Gram-negative (Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853), and environmental drug-resistant isolates (S. aureus B1, Enteroccoccus faecalis W1, and E. coli G1), as well as for their epidermal growth factor receptor (EGFR) of tyrosine kinase inhibitory activity. Only 1,5,6-trihydroxy-(4), 1,6,7-trihydroxy-(5), and 1,3,6,7-tetrahydroxyxanthones (6) exhibited antibacterial activity against Gram-positive bacteria, however none was active against vancomycin-resis...
