In the present study, we investigated the effects of anthraquinone derivatives isolated from rhubarb on platelet activity.
METHODS AND RESULTS:
Of four anthraquinone derivatives isolated from rhubarb examined, Chrysophanol 8-O-glucoside (CP-8-O-glc) was found to have the most potent inhibitory effect on collagen- and thrombin-induced platelet aggregation. Chrysophanol 8-O-glucoside-treated mice showed significantly prolonged bleeding times. Furthermore, Chrysophanol 8-O-glucoside was found to have a significant inhibitory effect on rat platelet aggregation ex vivo and on thromboxane A(2) formation in vitro. In coagulation tests, Chrysophanol 8-O-glucoside did not alter prothrombin time, and it prolonged the activated partial thromboplastin time. However, Chrysophanol 8-O-glucoside only inhibited platelet phosphatidylserine exposure, but not exert direct inhibition on intrinsic factors.
CONCLUSIONS:
This study demonstrates the antiplatelet and anticoagulant effects of Chrysophanol 8-O-glucoside and suggests that this compound might be of therapeutic benefit for the prevention of platelet-related cardiovascular diseases. | | Drug Discov Ther. 2013 Dec;7(6):212-24. | | Traditional Chinese medicine and related active compounds: a review of their role on hepatitis B virus infection.[Pubmed: 24423652] | Over a long period of time in clinical practice and in basic research progress, the effectiveness and beneficial contribution of TCM on CHB have been gradually known and confirmed.
METHODS AND RESULTS:
Based upon our review of related papers and because of our prior knowledge and experience, we have selected some Chinese medicines, including Chinese herbal formulas (e.g., Xiao-Chai-Hu-Tang, Xiao-Yao-San, and Long-Dan-Xie-Gan-Tang), single herbs (e.g., Phyllanthus niruri, Radix astragali, Polygonum cuspidatum, Rheum palmatum, and Salvia miltiorrhiza) and related active compounds (e.g., wogonin, artesunate, saikosaponin, astragaloside IV, and chrysophanol 8-O-beta-Dglucoside(Chrysophanol 8-O-glucoside)) and Chinese medicine preparations (e.g., silymarin, silibinin, kushenin, and cinobufacini), which seem effective and worthy of additional and indepth study in treating CHB, and we have given them a brief review. We conclude that these Chinese herbal medicines exhibit significant anti-HBV activities with improved liver function, and enhanced HBeAg and HBsAg sero-conversion rates as well as HBV DNA clearance rates in HepG2 2.2.15 cells, DHBV models, or patients with CHB.
CONCLUSIONS:
We hope this review will contribute to an understanding of TCM and related active compounds as an effective treatment for CHB and provide useful information for the development of more effective antiviral drugs. |
