| overview | cardiovascular disease is a serious threat to human health. the disease has the characteristics of "high morbidity, high disability and high mortality" and has become the number one cause of human death. Therefore, finding drugs that can effectively treat cardiovascular diseases has become the primary clinical problem. The traditional Chinese medicine for promoting blood circulation and removing blood stasis has been widely used in the treatment of cardiovascular diseases because of its effects of removing blood stasis and pain, promoting blood circulation and dredging meridian. Studies have found that salvianolic acid (salvianolicacids) is the most abundant water-soluble substance in Salvia miltiorrhiza (Latin scientific name: salviamiltiorrhizabunge), while salvianolic acid B is the compound with the most content and the strongest biological activity in salvianolic acid. Studies have shown that salvianolic acid not only has a protective effect on myocardial ischemia/reperfusion injury, but also has a protective effect on myocardial infarction and myocardial cell fertilization. |
| pharmacological action | protective effect of salvianolic acid B on myocardial infarction: a rat myocardial infarction (myocardialinfarction,MI) model was established by coronary artery ligation to investigate the protective effect of salvianolic acid B on MI. The results showed that compared with the control group, salvianolic acid B can exert obvious cardioprotective effect on MI. Mechanism studies show that salvianolic acid B mainly plays a role in protecting the heart by inhibiting the up-regulation of leptin and endothelin-reactive oxygen species (ET-ROS) and restoring the normal expression of sarcoplasmic reticulum calcium ATPase 2a(sarco/endoplasmicreticulumATPase2a,SERCA2a) and phosphoprotein in myocardial central muscle cells. salvianolic acid B has the effect of inhibiting myocardial cell hypertrophy: the effect of salvianolic acid B on myocardial cell hypertrophy induced by angiotensin Ⅱ(angiotensin Ⅱ,Ang Ⅱ) in neonatal rats was investigated. The results showed that salvianolic acid B can inhibit myocardial cell hypertrophy induced by Ang Ⅱ, and the expression of atrial natriuretic peptide and brain natriuretic peptide mRNA decreased and cell surface area decreased. Mechanism studies have found that salvianolic acid B can inhibit the activity of polyadenosine diphosphate ribose polymerase 1[poly(ADP-ribose)polymerase-1,PARP-1]. At the same time, it is found that overexpression PARP-1 can weaken the effect of salvianolic acid B on myocardial cell hypertrophy. These studies show that salvianolic acid B has a good effect on inhibiting myocardial cell hypertrophy. |
