Tanshinone IIA is a diterpene quinone isolated from the roots of Salviamiltiorrhiza bunge that has traditionally been used in China for the treatment of cardiovascular and cerebrovascular disorders. Although there is recent evidence showing that tanshinone IIA has an anti-obesity effect, its underlying mechanism of anti-obesity effect is poorly understood. Here, we investigated the effect of ta...

Neutrophils play a critical role in the initiation and maintenance of intestinal inflammation. However, conventional neutrophil-targeted therapies can impair normal host defense. Tanshinone IIA has been recently revealed to act directly on neutrophils. Hence, we aimed at investigating whether Tanshinone IIA can protect against experimental colitis through modulation of neutrophils. We induced c...

Pathological cardiac hypertrophy induced by adrenergic overactivation can subsequently develop to heart failure which remains as a leading cause of mortality worldwide. Tanshinone IIA is a lipid-soluble pharmacologically active compound extracted from the rhizome of the Chinese herb Salvia miltiorrhiza, a well-known traditional Chinese medicine used for the treatment of cardiovascular disorders...

The role of cell adhesion molecules has been studied extensively in the process of inflammation, and these molecules are critical components of carcinogenesis and cancer metastasis. This study investigated the effect of tanshinone I derived from the traditional herbal medicine, Salvia miltiorrhiza Bunge, on the expression of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion ...

Tanshinone IIA is one of the major diterpenes from Salvia miltiorrhiza Bunge and has been shown to possess a protective effect on the endothelial cells. The present study aimed to investigate whether tanshinone IIA could protect against methylglyoxal (MGO)-induced injury in human brain microvascular endothelial cells (HBMEC). Using cultured HBMEC, cell viability was measured by MTT assay and tr...

Tanshinone I (Tanshinone-1), a major active principle of Salvia miltiorrhiza (Danshen), has been shown to overcome tumor drug resistance and metastasis. Here we report that tanshinone-1 inhibits angiogenesis. Tanshinone-1 inhibited proliferation, migration and tube formation of vascular endothelial cells, rat aortic ring sprouting and the neovascularization of the chick chorioallantoic membrane...

Tanshinone IIA is a widely used Chinese herbal medicine isolated from Danshen (Salvia miltiorrhiza). Recent studies indicate that tanshinone IIA may have anti-inflammatory and anti-oxidant properties, as well as cytotoxic activities against multiple human cancer cell lines. This study was performed to determine the anti-cancer activity of tanshinone IIA on human breast cancer cells in vitro and...

Colorectal cancer (CRC) is one of the most common malignancies worldwide and a leading cause of cancer death. Despite decades of intensive investigations, effective interventional options are still limited and patient prognosis remains poor. Tanshinone I, an active compound from traditional Chinese herbal medicine Salvia miltiorrhiza Bunge, has been shown to inhibit cell growth of leukemia, lun...

A new high-performance liquid chromatography (HPLC) stationary phase was firstly synthesized based on the ionic liquid 2-ethyl-4-methylimidazole chloride. And the performances of the resulting stationary phase were determined by Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), and (13)C nuclear magnetic resonance (NMR) spectroscopy. The retention characteristics of the resu...

The objective of this paper was to investigate the extraction process of tanshinone IIA and its mechanism of induction of gastric cancer SGC7901 cell apoptosis. Extraction process of tanshinone IIA was optimised by orthogonal experimental method, and its effect on gastric cancer SGC7901 cell apoptosis was observed using MTT assay and electron microscopy. The optimum extraction process of tanshi...
