Nota: 1. Si prega di assicurarsi che il liquido sia limpido prima di aggiungere il solvente successivo.
2. Assicurarsi di aggiungere il/i solvente/i in ordine. È necessario assicurarsi che la soluzione ottenuta, nell'aggiunta precedente, sia una soluzione limpida prima di procedere all'aggiunta del solvente successivo. Metodi fisici come il vortex, gli ultrasuoni o il bagno d'acqua calda possono essere utilizzati per facilitare la dissoluzione.

Meccanismo d'azione (Mechanism of Action)

Targets/IC₅₀/Ki	SIRT
In vitro	Salvianolic acid B, also known as satanic acid B or lithospermic acid B, is a new generation of the natural antioxidants. It can influence Ca2+ aggregation and endothelial cell NO release of hypoxia/ reoxygenation-induced cell. When this compound concentration is 2.5, 5, and 10 mg/l, cell viability and superoxide dismutase (SOD) activity are enhanced, and the formation of malondialdehyde (MDA) in human umbilical vein endothelial cells (ECV304) is inhibited. SalB inhibits HG-induced oxidative stress and reduces the generation of ROS and 8-hydroxy-2-deoxyguanosine (8-OHDG) and mitochondrial depolarization and apoptosis in a dose-dependent manner. It can downregulate the expression of Bax and AIF nuclear translocation and cytochrome c release mediated by HG, but upregulate the expression of Bcl-2 induced by HG. Besides, this chemical attenuates HG-induced caspase of the enzyme 3, 9 and minimize PARP cleavage of Schwann cells (SCs). It inhibits angiotensin II or H2O2 and TNF-α-induced gelatinolytic activity in human aortic smooth muscle cells (HASMCs) in a concentration-dependent manner. This compound can inhibit platelet aggregation and adhesion. It can promote cardiac angiogenesis effect. SalB can enhance cell activity and reduce the number of sub-G1 and apoptotic nuclei of ischemic cell model in order to show its antiapoptotic effects. It inhibits ischemia and hypoxia of myocardial injury. This chemical inhibits the synthesis of type I collagen of non-TGF-1 stimulated human hepatic stellate cell line (LX-2). SalB activates mammalian sirtuins 1 (SIRT1), an NAD-dependent class III histone deacetylase (HDAC) that plays important roles in several physiological processes, including gene transcription, senescence, energy metabolism, oxidative stress and inflammation. (HG：High glucose)
In vivo	Salvianolic acid B can significantly reduce the myocardial infarct size and blood lactate dehydrogenase level of model rat with acute myocardial infarction, improve cardiac function and myocardial tissue structure, thus inhibiting ischemia and hypoxia of myocardial injury. This compound can improve blood hemorheology, reduce oxidative damage, improve the vascular endothelial cell function, and prevent the development of coronary artery disease. It could selectively inhibit the activity of MMP-9 in a rat model of myocardial infarction. This chemical can also effectively increase the thickness of the left ventricular wall in the myocardial infarction rats to improve the contraction of the heart, and reduce cardiac fibrosis. SalB treatment ameliorates ethanol-induced hepatic inflammation by decreasing the levels of hepatotoxic cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). It has beneficial effects against hepatic fibrosis in animal models and has been shown to possess cardioprotective and neuroprotective activity via anti-oxidative and anti-inflammatory actions.
