BACKGROUND Promotion of endothelial normalization restores tumor oxygenation and obstructs tumor cells invasion, intravasation, and metastasis. We therefore investigated whether a vasoactive drug, tanshinone IIA, could inhibit metastasis by inducing vascular normalization after palliative resection (PR) of hepatocellular carcinoma (HCC). METHODS A liver orthotopic double-tumor xenograft model...
The effects of tanshinone IIA on the proliferation of the human non-small cell lung cancer cell line A549 and its possible mechanism on the VEGF/VEGFR signal pathway were investigated. The exploration of the interaction between tanshinone IIA and its target proteins provides a feasible platform for studying the anticancer mechanism of active components of herbs. The CCK-8 assay was used to eval...
Tanshinone IIA, one of the main active components from the Chinese herb Danshen, is widely used to treat cardiovascular diseases in Asian countries, especially in China. To further elucidate its heart rate-reducing and anti-ischemic mechanisms, here we investigated the effects of tanshinone IIA on hyperpolarization-activated cyclic nucleotide-modulated (HCN) channels expressed in Xenopus oocyte...
Acute kidney injury (AKI) remains challenging for clinical practice and poses a risk of developing progressive chronic kidney disease (CKD) with no definitive treatment available yet. Tanshinone IIA, an active ingredient of Chinese herbal Salvia miltiorrhiza, has been widely used in Asia for the remarkable organoprotective activities. Its effect on established AKI, however, remains unknown. In ...
Glutamate excitotoxicity is associated with many neurological diseases, including cerebral ischemia and neurodegenerative diseases. Tanshinone IIA, a diterpenoid naphthoquinone from Salvia miltiorrhiza, has been shown to suppress presynaptic glutamate release, but its protective mechanism against glutamate-induced neurotoxicity is lacking. Using SH-SY5Y human neuroblastoma cells, we show here t...
This study evaluates the proliferative effects of danshen and its monomer extract, tanshinone IIA, on Schwann cell proliferation. A piece of silicone rubber was guided across a 15-mm gap in the sciatic nerve of a rat. This nerve gap was then filled with different concentrations of danshen (0-100 mg/mL). The results showed that danshen increased the expressions of uPA, cyclin D1, E and ERK, JNK,...
Tanshinone IIA (C19H18O3) was extracted from danshen (Salviae miltiorrhizae radix). It has cytotoxic properties and induces apoptosis in many human cancer cells. The molecular mechanisms are poorly understood, therefore, in the present study, we aimed to elucidate its anticancer activity on human breast cancer MDA-MB-231 cells. The cytotoxic effects of tanshinone IIA on MDA-MB-231 cells were me...
Tanshinone IIA has definite protective effects on various cardiovascular diseases. However, in hypertension-induced left ventricular hypertrophy (H-LVH), the signaling pathways of tanshinone IIA in inhibition of remodeling and cardiac dysfunction remain unclear. Two-kidney, one-clip induced hypertensive rats (n = 32) were randomized to receive tanshinone IIA (5, 10, 15 mg/kg per day) or 5% gluc...
The root of Salvia miltiorrhiza (Tan shen) has been used as a traditional drug for circulatory disorders including ischemic diseases such as angina pectoris. Effective components protecting the myocardium against ischemia-induced metabolic disturbances; tanshinone IIA, tanshinone I, tanshinone V, tanshinone VI, and dihydrotanshinone were isolated. Among them, we found tanshinone VI as the most ...
This study describes a simple, easy and inexpensive method for extracting tanshinone IIA and cryptotanshinone from Salvia miltiorrhiza by sonication or decoction. A comparison of sonication and decoction showed a similar yield for cryptotanshinone, while the tanshinone IIA yield was slightly higher using sonication. An analytical method for detecting tanshinone IIA and cryptotanshinone in extra...
