История

The study of the chemical composition of Salvia miltiorrhiza began in the 1930s. Japanese scholars first extracted three kinds of liposoluble components from Danshen. They are tanshinones I, II, and III.

Использование

Tanshinone IIA is a derivative of Tanshinone and acts as a potential inhibitor of tumor growth in vivo. Also maintains vasodilating activity in vivo.

Фармаколо?гия

Long-term researches show that tanshinone exhibits a variety of pharmacological effects, such as the protection of the cardiovascular system, anti-infective effects, and antioxidant effects. As for the domestic pharmacological study of tanshinone IIA, it was first started in the Shanghai Institute of Chinese Medicine. Professor Ding Guangsheng discussed the cardiovascular effects of tanshinone IIA.?He found that intraperitoneal injection of tanshinone IIA sodium sulfonate (200?mg/kg) significantly prolonged the survival time of mice under hypoxia atmosphere, and an increase in cardiac output was observed in a dog under anesthesia with a one-time intravenous injection of 20? mg/kg . In recent years, the mechanism of tanshinone IIA is increasingly brought to further research. Tanshinone IIA can increase the activity of superoxide dismutase (SOD) and interfere with the pathological process of many diseases, especially in cardiovascular diseases. It can attenuate the damages from the reactive oxygen species to vascular endothelial cells, lower the risk of atherosclerosis, and reduce the formation of atheromatous plaque. tumor cells and the expression of various genes connected with the proliferation, differentiation, and apoptosis of tumor cells. It may also have something to do with the inhibition of telomerase activity in tumor cells, changes in antigen expression on tumor cell surface, etc.
