Andrographolide is the most abundant diterpene lactone in Andrographis paniculata, which is widely used as a traditional medicine in Southeast Asia. Heme oxygenase 1 (HO-1) is an antioxidant enzyme encoded by a stress-responsive gene. HO-1 has been reported to inhibit the expression of adhesion
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,
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 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
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
The immunomodulatory properties of a diterpene lactone andrographolide and Kan Jang--a standardized fixed combination of Andrographis paniculata extract SHA-10 and Eleutherococcus senticosus extract SHE-3 were investigated. Their role on spontaneous and phytohemagglutinin (PHA)-induced proliferation
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
Oxidative stress can be involved in several cellular responses, such as differentiation, apoptosis and necrosis. Dehydrocrotonin (DCTN, diterpene lactone) from Croton cajucara, Brazilian medicinal plant, slightly induced NBT-reducing activity. In presence of protein phosphatase inhibitors
