Although tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promised anticancer medicine targeting only the tumor, most cancers show resistance to TRAIL-induced apoptosis. For this reason, new therapeutic strategies to overcome the TRAIL resistance are required for more effective tumor treatment. In the present study, potential of tanshinone IIA as a TRAIL sensitizer was evalu...

Tanshinone IIA exerts anti-inflammatory effects and influences electron transfer reaction in mitochondria. In the present study, we demonstrated that tanshinone IIA increased intracellular production of reactive oxygen species (ROS), which in turn induces heme oxygenase-1 (HO-1) expression in RAW 264.7 macrophages. Tanshinone IIA inhibited COX-2 and iNOS expression in lipopolysaccharide-activat...

Tanshinone IIA, extracted from Salvia miltiorrhiza Bunge, exerts neuroprotective effects through its anti-inflammatory, anti-oxidative and anti-apoptotic properties. This study intravenously injected tanshinone IIA 20 mg/kg into rat models of spinal cord injury for 7 consecutive days. Results showed that tanshinone IIA could reduce the inflammation, edema as well as compensatory thickening of t...

Production of tanshinones (tanshinone I and IIA) was determined in roots of Salvia przewalskii micropropagated plants. It was found that the total tanshinone content (tashinone I and tashinone IIA) was dependent on the age of the analyzed plants. The roots of 2-year-old in vitro regenerated plants at flowering stage produced highest tanshinone levels (3.8 mg/g dry weight of tanshinone I and 7.6...

derivative of tanshinone IIa, which is the main lipophilic component contained in Salvia miltiorrhiza known as ‘Danshen’ in traditional Chinese medicine. The pharmacological activity of STS is due to tanshinone IIA, which is a cardioprotective substance and may exert a beneficial effect on the clinically important vascular endothelium. The use of tanshinone IIA is limited by its poor water solu...

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...

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 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...

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...

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...
