The half-effective dose(ED50), therapeutic index(TI) and certain safety factor(CSF) of 7 diterpene lactone epoxide compounds with antiinflammatory and immunosuppressive action extracted from Tripterygium wilfordii (TW) were assayed using croton oil-induced ear swelling and hemolysin-antibody
Ginkgo biloba L. (Ginkgoaceae) is a traditional Chinese medicine known to treating stroke and other cardio-cerebrovascular diseases for thousands of years in China. Ginkgo diterpene lactones (GDL) attracted much attention because of their neuroprotective The male antifertility activities under equal toxic dosages 1/10-1/60 LD50 and hemolysin antibody formation parameters under effective threshold dosages respectively of 7 diterpene lactone epoxide compounds extracted from Tripterygium wilfordii (TW) were assayed in mice. The results indicated that
The inhibitory effects and their IC50 values of Tripterygium wilfordii (TW) on T and B lymphocytes were assayed using mice splenocytes induced to proliferate by mitogens ConA and LPS in vitro. The results indicated that 6 compounds (T4,T7,T8,T9,T10,L2) and component T1 had significant inhibitory
Andrographolide (1) is a major diterpene lactone exhibiting anti-inflammatory effects and is found in the plant Andrographis paniculata (Burm. f) Nees, which is widely used in Traditional Chinese Medicine. Synthesis of more effective drugs from andrographolide is very interesting and can prove to be
Andrographis paniculata Nees is an official herbal medicine for treatment of infection and inflammation in China. Andrograpanin, the one of diterpene lactones in A. paniculata, is a hydrolysate from neoandrographolide in vivo and in vitro. The goal of the present study was to investigate
Andrographolide is a main bioactive diterpene lactone in A. paniculata with anti-inflammatory activity. In this study, a series of andrographolide derivatives were synthesized and evaluated for their structure-anti-inflammatory activity relationships in vivo. Among all compounds, isoandrographolide
Neoandrographolide, one of the principal diterpene lactones, isolated from a medicinal herb Andrographis paniculata Nees, was tested in vivo and in vitro for its anti-inflammatory activities and mechanism. Oral administration of neoandrographolide (150 mg/kg) significantly suppressed ear edema
Andrographolides, a type of diterpene lactone, are widely known to have anti-inflammatory and anti-oxidative properties. CHP1002, a synthetic derivative of andrographolide, has similar anti-inflammatory action in mouse ear swelling test and rat paw edema test. In the present study, the mechanism of
Ginkgo biloba L. is a kind of traditional Chinese medicinal material with a long history. Its main active components, ginkgolides, can be used for the treatment of stroke and other cardio-cerebrovascular diseases. Ginkgo Diterpene Lactone Meglumine Injection (GDLI) as a modernized TCM The diterpene lactone andrographolide, isolated from Andrographis paniculata, has been proven to possess several important protective biological activities, including antioxidant, anti-inflammatory, immunomodulatory, antiseptic, antimicrobial, cytotoxic, hypolipidemic, cardioprotective,
The rhizome of Dioscorea bulbifera Linn, traditionally used to treat thyroid disease and cancer in China, is reported to induce serious liver injury during clinical practice. Diosbulbin B (DB), a diterpene lactone, has been found to be the main toxic compound in D. bulbifera. The present study aims
The phytochemical study of the aerial parts of Melampodium perfoliatum afforded six melampolides (1, 3, 5-8), a eudesmanolide (9), two diterpene lactones (10, 11), and two ent-kaurane derivatives (12, 13), together with the known melampodin (2) and polymatin A (4). The structures of the compounds
Andrographis paniculata is an herb widely used in China, Korea, and India for its anti-hepatotoxic, anti-viral, and anti-inflammatory effects. Andrographolide is the major bioactive diterpene lactone in A. paniculata. The pi class of glutathione S-transferase (GSTP) is one of the phase II
Several lines of evidence indicate that inflammation and endothelial cell dysfunction are important initiating events in atherosclerosis. Tumor necrosis factor-α (TNF-α), a pro-inflammatory cytokine, induces the expression of cell adhesion molecules and results in monocyte adherence and atheromatous
