Triptolide Chemical Properties,Uses,Production

Tripterygium wilfordii

There are four species under the genus Tripterygium in the world, and all are native to China, with three species being medicine. Tripterygium wilfordii is a woody climber, 2-3 meters high. Branchlets are reddish and with brown angular, with oblong tuberculate projections and iron brown hairs. Flowering period is from May to June. Fruit ripening period is from August to September. It grows in shady and humid slopes, valleys, bushes besides streams and secondary miscellaneous forests, with the distribution in the south of the Yangtze River, Anhui, Zhejiang, Fujian, Taiwan, Jiangxi, Hunan, Guangdong and even the southwest provinces. It is harvested in summer or autumn. It is bitter and poisonous, and can be used as insecticide, anti-inflammatory and detoxification. This product is poisonous, thus be careful when orally taking in.
1.Treatment of rheumatoid arthritis: smash the roots and leaves of Tripterygium wilfordii and apply it externally. Remove it half an hour later, otherwise blister could occur. (Jiangxi, " Handbook of Herbs").
2. Treatment of skin itchiness: smash the leaves of Tripterygium wilfordii and apply it ( "Medicinal Flora in Hunan").
3. Treatment of snake strand sore: grind the flowers of Tripterygium wilfordii and the root of three-nerved spicebush, and apply it the affected area (“ Medicinal Flora in Hunan ").

Anti-inflammatory and immunosuppressive effects

Triptolide is an epoxy diterpene lactone compound that extracted from the roots, leaves, flowers and fruits of Tripterygium wilfordii (Celastraceae). Triptolide, with alkaloids like wilfordine, wilforine, wilforgine, Wilfortrine, wilfozine and Wilfornine, constitutes the main active ingredient of Tripterygium extraction. It is insoluble in water, soluble in methanol, dimethyl sulfoxide, ethanol, ethyl acetate, chloroform ect. It has anti-inflammatory and immunosuppressive effects: with the application of 10μg/kg sc Triptolide in continuous 10 days, the croton oil-induced ear edema in mice can be reduced. The in vitro tests with the application of 0.05~1μg/ml Triptolide in continuous 7 days showed this product has a stabilizing effect on sheep erythrocyte membrane; with the application of 75,150mg/kgsc Triptolide in continuous 7 days, the total complement levels of rat serum significantly increased, and the formation of hemolysin antibody in primary immune response was significantly inhibited, but no significant inhibition was found in the formation of hemolysin antibody in the second immune response; with the application of 150μg/kg ig Triptolide in continuous 7 days, a certain degree of inhibition in mouse peritoneal phagocytic function; with the application of 300μg/kg sc Triptolide in continuous 15 days, the croton oil-induced ear edema in mice was inhibited; with the application of 75,150μg/kgsc Triptolide in continuous 14 days, the carrageenan paw swelling in rat was inhibited; with the application of 0.22~4.44μg/ml Triptolide in Polygalatenuifolia extraction, a protective effect on RBCM of rats was showed; with the application of 0.25,1mg/kg ip Triptolide, antibody production and secretion in mice were inhibited (QHS method); with the application of 50,500ng/ml concentration, proliferative responses of T cell and B cell were significantly inhibited; with the application of 5,50,500ng/ml Triptolide in vitro and 0.5,0.75,1mg/kg ip drug in vivo, the production of mouse spleen cells IL-2 was significantly inhibited; with the application of 0.1~1μg/ml Triptolide in vitro, Con A-induced lymphocyte growth was inhibited; with the application of 0.5~10μg/L Triptolide the mixed lymphocyte culture (MLC) was inhibited: after 60Co irradiation, the mixed lymphocyte that induced with the concentration of 5,10μg/L Triptolide inhibited the second MLC, showing that triptolide can induce suppression T cells (Ts); with the application of 0.12~0.5mg/kg ip Triptolide, the DNFB-induced DTH in mice was significantly inhibited; with the application of 0.25,0.5mg/kg Triptolide, the secretion activity of mice spleen cells IL-2 was inhibited, and the increased DTH responses that induced by high-dose cyclophosphamide was also inhibited; with the application of 0.25mg/kg Triptolide, mouse thymus Th/Ts cell ratio reduced. Experimental results indicate that triptolide has immunosuppression, and the mechanism may be related to inhibition of Th cells and secretion activity of IL-2 and inducing Ts cells.

Anti-cancer effects

In recent years, a large number of in vitro and in vivo studies demonstrated this product has good anti-tumor activity to a variety of cancers such as leukemia, breast cancer, pancreatic cancer and lung cancer. Recent studies have found that triptolide not only affects certain proteins and signaling pathways specifically, but also inhibits broad gene transcription, but the mechanism remains to be further clarified.
Yu Qiang group in Shanghai Institute of Materia Medica of Chinese Academy of Sciences studied in-depth the molecular mechanisms of Triptolide in suppressing broad gene transcription. The study found that Triptolide inhibited gene transcription by promoting the phosphorylation of the largest and most important functional subunit Rpb1 in RNA polymerase II, and subsequent Rpb1 ubiquitin degradation. PTEF-b, the upstream kinases of Rpb1, plays a positive role in the regulation of phosphorylation process of Rpb1 that induced by Triptolide. The study also found that Triptolide could induce DNA damage. These results indicate that triptolide suppresses broad gene transcription by causing DNA damage in cells and thus activating the P-TEFb, which can phosphorylate Rpb1 and cause Rpb1 degradation.
