Embodiment 3

[0156] Embodiment 3: Danshensu (DSS) to the attenuation and synergistic effect of Tanshinone I (TI)

[0157] The experimental materials and experimental methods are the same as those in Example 1 and Example 2, and the experimental results are as follows.

[0158] 1. In vitro study on the cytotoxicity of tanshinone I and the attenuation of tanshenin

[0159] The primary cardiomyocytes of suckling rats were treated with tanshinone I for 24 hours, and the cell viability was measured after 1 week of culture. The experimental results showed that when the concentration of tanshinone I was higher than 2 μM, there was a certain cytotoxic effect (compared with the control group, P Figure 10 and Table 6. When the administration concentration of tanshinone I was 4 μM, different concentrations of danshensu were given. When the concentration of danshinone was higher than 37.5 μM, the cell death caused by tanshinone I could be effectively reversed (P Figure 11 and Table 7.

Abstract

The invention discloses a pharmaceutical composition for treating myocardial infarction. The pharmaceutical composition comprises a tanshinone compound shown in a formula (I) and a phenolic acid compound containing one or more substituent shown in a formula (II), preferably, comprises tanshinone I and tanshinol or tanshinone IIA and salvianolic acid B or dihydrotanshinone I and protocatechualdehyde or cryptotanshinone and salvianolic acid C. According to the invention, the phenolic acid compound containing the specific substituent and the tanshinone compound having a specific structure are prepared to obtain the pharmaceutical composition. The pharmaceutical composition can effectively reduce the myocardial infarction area of mice with acute myocardial infarction, and has low toxic and side effects; the phenolic acid compound in the composition can obviously reduce the in vitro and vivo toxic and side effects of the tanshinone compound, and can enhance the cardiac muscle protection effect of the tanshinone compound on the mice with acute myocardial infarction.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to a combined medicine of known chemical components, in particular to a pharmaceutical composition for treating myocardial infarction. Background technique [0002] Acute myocardial infarction (AMI) is the most serious coronary artery disease, accounting for one-third of the annual deaths in developed countries. In the United States, more than 2.4 million people died of myocardial infarction, and in Europe and northern Asia, more than 4 million people died of myocardial infarction [Worldwide trends in bloodpressure from 1975 to 2015: apooled analysis of 1479 population-based measurement studies with 19 1 million participants, Lancet. 2016 Nov 15.pii:S0140-6736(16)31919-5]. In recent decades, percutaneous coronary intervention or thrombolytic therapy has been used to reduce the mortality rate of coronary heart disease. Drugs are mostly used for secondary prevention. Currently, the clinically u...
