MYC2 is a core transcription factor in the plant response to jasmonates. It also functions in secondary metabolism and various processes for growth and development. However, the knowledge about its role in Salvia miltiorrhiza is still very limited. We determined that the biosynthesis of salvianolic acid B (Sal B) was strongly induced in 2-month-old transgenic plants that over-expressed SmMYC2. In the roots of transgenic line 12 that over-expressed SmMYC2 (OEM-12), the Sal B concentration was as high as 5.95 ± 0...

Arsenic trioxide (ATO) is a potent anticancer agent used to treat acute promyelocytic leukemia. However, its cardiotoxicity limits ATO's widespread clinical use. Previous studies demonstrated that ATO may aggravate Ca2+ overload and promote endoplasmic reticulum stress (ERS). Salvianolic acid B (Sal B) is cardioprotective against ATO and enhances ATO's anticancer activities. The present study assessed whether the Sal B protective effect was related to maintenance of Ca2+ homeostasis and inhibition of ER stress...

AIMS: To explore the effect of salvianolic acid B (Sal B) on regulation of SIRT3/FOXO1 signaling pathway in rats with non-alcoholic steatohepatitis (NASH). METHODS: Sixty Sprague Dawley (SD) rats were randomly divided into control, model and treatment groups. After 12 weeks of successful model establishment with high fat diet, treatment group was given Sal B by intragastric administration. After 12 weeks of treatment, rats were sacrificed and livers were taken to test indicators such as liver index, TG, TC, ALT, AST, reactive oxygen species (ROS) by DCFH-DA probe, SOD2 activity by WST-8 test...

BACKGROUND: The NLRP3 inflammasome activation and neuroinflammation are known to be involved in the pathology of depression, whereas autophagy has multiple effects on immunity, which is partly mediated by the regulation of inflammasome and clearance of proinflammatory cytokines. Given the emerging evidence that autophagy dysfunction plays an essential role in depression, it is very likely that autophagy may interact with the inflammatory process in the development and treatment of depression...

Our previous study indicated that Salvia miltiorrhiza (SM) induced human placenta‑derived mesenchymal stem cells (hPDMSCs) to differentiate into cardiomyocytes, however, the effective component of SM in promoting cardiomyogenic differentiation remained to be elucidated. In the present study, the most commonly examined components of SM, including danshensu, salvianolic acid B, protocatechuic aldehyde, tanshinone I (TS I), TS IIA and cryptotanshinone, were used to determine the effective components of SM in promoting cardiomyogenic differentiation...

The purpose of this study was to evaluate the cerebral protection of salvianolic acid B (Sal B) against cerebral I/R injury and investigate the underlying mechanism. As shown by 2,3,5-Triphenyltetrazolium chloride (TTC) staining and magnetic resonance imaging (MRI) analyses, Sal B significantly reduced cerebral infarct size, and accompanied with improved neurobehavioral functions as indicated by the modified Bederson score and Longa five-point scale. Sal B decreased the production of reactive oxygen species (p<0...

Kidney-specific delivery is critically important for the treatment of renal fibrosis with drugs such as salvianolic acid B (Sal B). Here we report a kidney-specific nanocomplex formed by the coordination-driven assembly of catechol-modified low molecular weight chitosan (HCA-Chi), calcium ions and Sal B. The prepared HCA-Chi-Ca-Sal B (HChi-Ca-Sal B) nanocomplex reversed the TGF-β1-induced epithelial-mesenchymal transition (EMT) in HK-2 cells. In vivo imaging demonstrated a kidney-specific biodistribution of the nanocomplex...

Ten caffeic acid derivatives (1-10) were isolated from the roots of Salvia miltiorrhiza by using various chromatographic methods and their chemical structures were spectroscopically elucidated. The absolute configurations of chiral centers were determined by comparison with reported coupling constants, optical rotation values, and CD techniques. Anti-inflammatory activities were evaluated using nitric oxide (NO), inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 inhibition assays, and by determining the expression of heme oxygenase (HO)-1...

Salvianolic acid B (SalB) is one of the most bioactive components extracted from Salvia miltiorrhiza, and its antioxidant capacity corresponds with its protective effects against cell injury from oxidative stress. The aim of the present study was to evaluate the effect of SalB on experimental pulmonary fibrosis and its ability to ameliorate the oxidative/antioxidative imbalance during fibrosis pathogenesis. The anti-fibrotic activity of SalB was first confirmed in Transforming growth factor β1(TGF-β1)-stimulated MRC-5 cells...

The quality of Danshen extract granules on market is largely different from each other mainly due to the heterogeneous quality of raw materials of Salvia miltiorrhiza, various producing procedures and lack of good quality evaluation method. Formula granule and "standard decoction" have the same quality. In this paper, a systematic evaluation method for the quality of Danshen decoction was established from the perspective of "standard decoction", in order to explore the main factors affecting the quality uniformity of Danshen extract granules...

BackgroundAims: Salvianolic acid B (SalB) is a natural polyphenolic compound enriched in Salvia miltiorrhiza Bunge. Our study was designed to explore the role of Sal B on cognitive impairment in vascular dementia (VD) model rats, as well as its possible molecular mechanisms. METHODS: Rats were randomly divided into four groups (n = 15 for each group): Control group, Sal B group (normal Sprague Dawley rats treated with Sal B), VD group and VD + Sal B group. The VD group rats were established by permanent bilateral common carotid artery occlusion (BCCAO)...

In this study, we analyzed danshen (Salvia miltiorrhiza) constituents using biopartitioning and microemulsion high-performance liquid chromatography (MELC). The quantitative retention-activity relationships (QRARs) of the constituents were established to model their pharmacokinetic (PK) parameters and chromatographic retention data, and generate their biological effectiveness fingerprints. A high-performance liquid chromatography (HPLC) method was established to determine the abundance of the extracted danshen constituents, such as sodium danshensu, rosmarinic acid, salvianolic acid B, protocatechuic aldehyde, cryptotanshinone, and tanshinone IIA...

The aim of the present study was to investigate the effect of salvianolic acid B (Sal B) and danshensu (DSU) on the osteogenic differentiation of bone marrow mesenchymal stem cells (MSCs) and the mechanisms of the effects. The osteogenic differentiation of MSCs in culture was assessed by measuring alkaline phosphatase (ALP) activity, osteocalcin (OCN) production, nitric oxide (NO) production and the mRNA expression levels of osteoprotegerin (OPG) and its ligand by MSCs. MSCs were successfully induced to differentiate into osteoblasts and adipocytes...

The present study tested the hypotheses that bone morphogenetic protein 2(BMP-2) combined with salvianolic acid B(Sal-B) enhance the differentiation of rat bone marrow mesenchymal stem cells (BMSCs) towards cardiomyocytes in vitro. BMSCs were treated with BMP-2 and Sal-B, alone or in combination, for 72 h, then added new media (excluding inductive substance) and cultured for 4 weeks. The morphologic characteristics, surface antigens and mRNA expression of several transcription factors were also assessed. We found that they could all be identified by the positive staining for cardiomyocyte-specific proteins, desmin and cardiac troponin T, in these cells...
