What is Salvianolic Acid B?

Cardiovascular disease is an illness that seriously threatens human wellness. It has the characteristics of “high morbidity, high disability rate, as well as high death price”. It has actually become the primary reason for human death. Consequently, locating drugs that can successfully deal with cardiovascular disease has actually become the key professional trouble. The traditional Chinese medication for advertising blood flow as well as getting rid of blood tension, Salvia miltiorrhiza, has actually been commonly made use of in the treatment of heart diseases as a result of its functions of getting rid of blood tension and also eliminating discomfort, promoting blood flow and also removing the meridians. Researches have found that salvianolic acids are the most bountiful water-soluble compounds in Salvia miltiorrhizabunge (Latin name: salviamiltiorrhizabunge), while salvianolic acid B is the most bountiful and biologically energetic substance in salvianolic acid. Studies have actually shown that salvianolic acid not only has a safety effect on myocardial ischemia/reperfusion injury, yet additionally has a safety effect on heart attack as well as myocardial cell hypertrophy.

Pharmacological Action and Application of Salvianolic Acid B

1) The protective effect of on myocardial infarction: The myocardial infarction (MI) model in rats was constructed by coronary ligation, and the protective effect of salvianolic acid B on MI was investigated. The results showed that compared with the control group, salvianolic acid B could exert a significant cardioprotective effect on MI. Mechanistic studies have shown that salvianolic acid B mainly inhibits the up-regulation of leptin and endothelin-reactive oxygen species (ET-ROS) and restores myocardial sarcoplasmic reticulum calcium ATPase 2a (sarco/endoplasmicreticulum ATPase 2a, SERCA2a) and phosphorus receptors in the myocardium. The normal expression of the protein, and then play a role in protecting the heart.

2) The protective effect of on MI/R injury: a large number of free radicals will be generated during MI/R, which will enhance the lipid peroxidation of cell membranes, change membrane fluidity and permeability, and lead to abnormal electrophysiological activities. , induce and promote arrhythmia. Due to the enhanced lipid peroxidation in myocardial cells, the content of peroxidation products such as malondialdehyde (MDA) in the myocardial ischemia area increases; lactate dehydrogenase (LDH) and creatine phosphokinase in coronary effluent (creatinephosphokinase, CPK) increased and myocardial tissue superoxide dismutase (superoxidedismutase, SOD) decreased. The study found that salvianolic acid B can significantly increase the SOD activity in myocardial tissue of MI/R-injured rats, and can effectively resist the toxic effect caused by oxygen free radicals, thereby reducing myocardial cell damage. The protective effect of salvianolic acid B on MI/R injury was investigated by constructing a rat MI/R model, and it was found that compared with the control group, administration of salvianolic acid B could significantly increase the levels of troponins (CTn) and creatine in plasma. The content of kinase isoenzyme (creatinekinase-MB, CK-MB), while significantly reducing the levels of nitric oxide (nitricoxide, NO) and total superoxide dismutase (total superoxide dismutase, TSOD) in plasma, indicating that Rat MI/R injury has obvious protective effect. Further research found that salvianolic acid B can alleviate oxidative stress, reduce calcium overload and improve endothelial function.

3) Has the effect of inhibiting cardiomyocyte hypertrophy: The effect of salvianolic acid B on angiotensinⅡ (AngⅡ)-induced cardiomyocyte hypertrophy in neonatal rats was investigated. The results showed that salvianolic acid B could inhibit AngⅡ Induced cardiomyocyte hypertrophy, decreased atrial natriuretic peptide and brain natriuretic peptide mRNA expression and decreased cell surface area. Mechanistic studies found that salvianolic acid B could inhibit the activity of poly(ADP-ribose)polymerase-1 (PARP-1); at the same time, it was found that overexpression of PARP-1 could attenuate the activity of salvianolic acid B Anti-cardiomyocyte hypertrophy effect, these studies show that salvianolic acid B has a good inhibitory effect on cardiomyocyte hypertrophy.

4)Can inhibit the formation of atherosclerosis: The effect of salvianolic acid B on atherosclerosis was investigated through experiments, and the results showed that the treatment of vascular smooth muscle cells with salvianolic acid B can effectively inhibit platelet-derived growth factor ( platelet-derived growth factor, PDGF)-induced cell proliferation and migration, and can significantly increase the expression of heme oxygenase-1 (hemeoxygenase-1, HO-1); at the same time, salvianolic acid can significantly reduce reactive oxygen species (reactive oxygen species) , ROS) production and reduction of nicotinamide adenine dinuclear

The ratio of nucleotide phosphate/reduced nicotinamide adenine dinucleotide phosphate (NADP/NADPH). Using human umbilical vein endothelial cells, it was found that salvianolic acid B can significantly induce the production of HO-1, and at the same time effectively inhibit the activation of nuclearfactor-κB (NF-κB) induced by tumor necrosis factor-α (TNF-α). Inhibition of HO-1 expression by siRNA abolished the protective effect of salvianolic acid on vascular endothelial cells and blocked the proliferation, migration and inflammation of HO-1-deficient cells. Further mechanism studies have shown that salvianolic acid B induces the expression of HO-1 by activating nuclear factor-E2-related factor2 (Nrf2), thereby inhibiting the proliferation, migration and inflammation of vascular cells, thereby exerting anti-inflammatory effects. The role of atherosclerosis.

5) Can effectively reduce portal hypertension: Endothelin-1 (ET-1) was used to induce portal hypertension in mice, and the effect of salvianolic acid B on blood microcirculation in the liver of mice with portal hypertension was investigated. , the results showed thatcompared with the control group,could significantly reduce the average blood flow and microcirculation flow rate in the liver of portal hypertension mice, and then play a role in reducing portal hypertension. Studies have shown that salvianolic acid B can reduce portal hypertension in rats, and studies have found that salvianolic acid B mainly acts through macrophages in the rat liver.

1) Akt-eNOS signaling mediates the protective effect of salvianolic acid B on MI/R injury: studies have found that Akt-eNOS is one of the components of the reperfusion injury salvagekinase (RISK) signal transduction pathway. The expression of related proteins has a protective effect on the heart. In this pathway, Akt is the central link and the main target enzyme. Only phosphorylated Akt can exert a series of biological activities. The rat MI/R injury model was prepared by ligating the coronary artery, and the protective effect of salvianolic acid B on MI/R injured rats was investigated. Studies have shown that can increase the phosphorylation level of Akt and lead to its activation. Akt further activates its downstream target eNOS to phosphorylate it, and then exerts a protective effect on MI/R injury through a series of downstream biological effects.

2) TLR4-NFκB-TNF-α inflammatory pathway mediates salvianolic acid B to protect cardiomyocyte injury: lipopolysaccharide (LPS) induces inflammatory injury of neonatal rat cardiomyocytes, and explores the effect of salvianolic acid B on cardiomyocyte injury protective effect. The results showed that the concentrations of lactate dehydrogenase and tumor necrosis factor-α in this group were significantly higher than those in other groups after LPS treatment, indicating that the modeling was successful; while after treatment with salvianolic acid B, the concentrations of LDH and TNF-α decreased significantly. . At the same time, immunohistochemical results showed that the expressions of Toll-like receptor 4 (TLR4) and NF-κB were significantly increased after LPS administration; expression decreased significantly. This indicates that in the early stage of cardiomyocyte injury induced by LPS, the TLR4-NF-κB-TNF-α pathway was rapidly activated, and played a role in protecting cardiomyocyte injury, probably by inhibiting this pathway. realized.

3) Autophagy-mediated salvianolic acid B to protect cardiomyocyte injury: The effect of autophagy on starved cardiomyocytes was investigated experimentally, and the effect of salvianolic acid B on autophagy in starved cardiomyocytes was also observed. The results showed that autophagy was induced in cardiomyocytes after 3 h of starvation, which led to cell damage, and the expression of LC3-II in starved cells was found to increase in a time-dependent manner. After administration of salvianolic acid B, LC3-II was significantly inhibited. At the same time, the cell viability and the level of ATP in cardiomyocytes also increased significantly. This study shows that salvianolic acid B can play a protective role by blocking excessive autophagy.

4) Mitochondrial apoptosis pathway mediates salvianolic acid B to inhibit myocardial cell apoptosis after myocardial infarction: The myocardial infarction model in rats was constructed by ligating the left anterior descending coronary artery, and then the effect of on myocardial cell apoptosis in myocardial infarction rats was investigated. impact of death. The results showed that salvianolic acid B could significantly reduce the apoptosis rate of cardiomyocytes. The authors further investigated the effect of salvianolic acid B on the expression of apoptosis-related genes, and found that could significantly reduce the expression of Bax, and also found that also significantly reduced the expression of STAT-3 and IL-6. This indicated that the mitochondrial apoptosis pathway was involved in regulating the apoptosis of cardiomyocytes after myocardial infarction by salvianolic acid B.
