diterpene lactone/neoplasms

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,

Triptolide, an epoxidated diterpene lactone compound separated from a traditional Chinese medicine, Tripterygium wilfordiiHook. f (TWHF), is responsible for the anti-tumor activity of TWHF with broad spectrum and high performance. The antitumor mechanism of triptolide locates in many fields, such as

OBJECTIVE To establish an HPLC-DAD/ESI-MS method for quickly identifying chemical constituents in diterpene lactone effective fraction of Andrographis panniculata and to study its pharmacodynamics. METHODS The separation was performed on an Agilent SB-C18 column (2.1 mm x 150 mm, 5 μm) with a mobile

There has been a paradigm shift in our understanding about the multifaceted nature of cancer, and a wealth of information has revealed that single-target drugs are not good enough to provide satisfactory clinical outcomes and therapeutic effects for complex diseases which involve multiple factors.

Matrix metalloproteinase-9 (MMP-9) plays a critical role in cancer metastasis. Andrographolide (AP) is a diterpene lactone in the leaves and stem of Andrographis paniculata (Burm. f) Ness that has been reported to possess anticancer activity. In this study, we investigated the effect of AP on

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

Andrographolide is one of the major diterpene lactones found in Andrographis paniculata Nees and exhibits remarkable inhibitory effects on various cancers. In this study, the antipulmonary cancer effects of andrographolide were studied in a lung tumor mouse model induced by human vascular

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

BACKGROUND Many studies have shown that Andrographis paniculata (Burm. f.) Nees has a good anti-tumor effect, but poor solubility in water and poor bioavailability hinder the modernization of it. METHODS To formulate the effective parts (mainly diterpene lactones) of Andrographis paniculata (AEP)

Andrographolide 1, a diterpene lactone of Andrographis paniculata, displays in vitro and in vivo antitumor activity against breast cancer models and mouse myeloid leukemia (M1) cells. In the present study, we report the semi-synthesis of andrographolide derivatives and their in vitro activity

Andrographolides, the diterpene lactones, are major bioactive phytochemicals which could be found in different parts of the medicinal herb Andrographis paniculata. A number of such compounds namely andrographolide (AG), neoandrographolide (NAG), and 14-deoxy-11,12-didehydroandrographolide (DDAG)
