Background Cardiac hypertrophy, characterized by the thickening of the heart muscle, arises from factors such as hypertension and genetic mutations, often leading to adverse outcomes like heart failure and arrhythmias. Guanxinning tablets (GXNT), a botanical drug composed of the blood-activating herbs Salvia miltiorrhiza Bunge. and Ligusticum striatum DC., are widely used in the treatment of cardiovascular diseases. However, the active ingredients and their molecular mechanisms are yet to be fully understood. Methods We evaluated the anti-hypertrophic effects of GXNT and screened its active substances via cardiac function live-imaging on an aristolochic acid A-stimulated zebrafish cardiac hypertrophy model, and through F-actin immunostaining on a phenylephrine-induced hypertrophic NRCMs model. Additionally, the protective effects of GXNT’s active substances were analyzed in a mouse model of cardiac hypertrophy using echocardiography, histopathology analysis, and western blotting. Results The anti-hypertrophic effects of GXNT were assessed using an aristolochic acid A-stimulated zebrafish model and phenylephrine-induced hypertrophic NRCMs. GXNT demonstrated significant anti-hypertrophic effects in both models. Phenotypic screening identified Senkyunolide I (Sen I) from Ligusticum striatum as the active component in the zebrafish model, while Salvianolic acid B (Sal B) and Rosmarinic acid from Salvia miltiorrhiza emerged as the key anti-hypertrophic compound in NRCMs. In a mouse model of isoproterenol-induced cardiac hypertrophy, Sal B and Sen I showed synergistic effects, improving cardiac function, reducing oxidative stress, and suppressing inflammation. Mechanistically, transcriptomic sequencing highlighted cooperative modulation of MAP3K1 signaling by the two compounds. Notably, siRNA-mediated knockdown of MAP3K1 in cardiomyocytes attenuated the hypertrophic phenotype, supporting its essential role in the pathological process. Molecular docking and dynamic simulations further supported their binding potential to MAP3K1. Conclusion These findings underscore GXNT’s potent anti-hypertrophic effects, possibly driven by the synergistic actions of Sal B and Sen I, and offer insights into its therapeutic potential through MAP3K1 signaling regulation.

Acute lung injury (ALI)/Acute Respiratory Distress Syndrome (ARDS) is a life-threatening condition marked by severe inflammatory responses and disruption of the alveolar-capillary barrier, leading to high mortality rates and lack of effective treatments. Recent research has underscored the crucial role of programmed cell death pathways-pyroptosis, apoptosis, and necroptosis-in exacerbating inflammation and barrier dysfunction in ALI/ARDS. However, effective therapeutic agents targeting this process remain scarce. In this study, we reveal that PANoptosis, which integrates these cell death pathways through the PANoptosome complex, plays a central role in the pathogenesis and progression of ALI/ ARDS. The levels of PANoptosis-related molecules were significantly elevated in both the ALI mice and the clinical ARDS patient samples, highlighting it as a novel therapeutic target. Building on this insight, we developed a multifunctional nanomedicine, TPNs/Sal B, which integrates tea polyphenol-based nanoparticles (TPNs), a bioactive nanomaterial with anti-pyroptotic and anti-necroptotic properties, with salvianolic acid B (Sal B), known for its anti-apoptotic effects. Our results demonstrate that the nanomedcine TPNs/Sal B effectively inhibit PANoptosis, thereby attenuating lung tissue pathological damage, reducing inflammation, and improving lung epithelial barrier function in ALI models. Moreover, we identified LIM and SH3 protein 1 (LASP1) which may play an critical role in modulating alveolar epithelial barrier function during ALI/ARDS progression, and treatment with TPNs/Sal B effectively restored LASP1 levels. Our findings underscore the therapeutic potential of TPNs/Sal B as a targeted treatment for ALI/ARDS, offering a promising strategy for modulating PANoptosis and preserving lung function.

The long-term reliability of small-diameter vascular grafts (SDVGs) is still largely confined by acute thrombosis, intimal hyperplasia and delayed endothelialization. In this study, a fibrous SDVG containing both physical and biochemical cues was developed to promote rapid endothelialization. The success of our method depends on the integration of a bi-oriented luminal surface with the conjugation of salvianolic acid B (Sal B) via aminolysis and subsequent amidation reaction. Specifically, longitudinally aligned poly (lactide acid-co-ε-caprolactone) (PLCL) microfibers having nano-grooved surface texture provided bi-oriented topographical cues to guide the elongation and migration of endothelial cells (ECs), whilst the incorporation of Sal B served as a biochemical signal to inhibit thrombosis, enhance EC growth and increase von Willebrand factor (vWF) expression in ECs. When implanted into a rat abdominal aorta defect model, the graft was able to facilitate luminal EC coverage, smooth muscle cells infiltration and collagen deposition without causing stenosis or thrombosis. The combination of bi-oriented topography with surface functionalization may become a platform design to maintain patency and accelerate in situ tissue regeneration of SDVG.

Background: Although chromatography and spectrometry-based methods have been used to analyse phenolic acids in Chinese traditional medicine Salvia miltiorrhiza Bunge (SMB), quantitative nuclear magnetic resonance (qNMR) has never previously been used to analyse fresh SMB root extracts.
Objective: To establish a fast and simple method of quantitating danshensu, lithospermic acid, rosmarinic acid, and salvianolic acid B content in fresh SMB root using 1H-NMR spectroscopy. Method: Fresh SMB root was extracted using a 70% methanol aqueous solution and quantitatively
analysed for danshensu, lithospermic acid, rosmarinic acid, and salvianolic acid B using 1H-NMR spectroscopy. Different internal standards were compared and the results were validated using highperformance liquid chromatography. Results: The established method was accurate
and precise with good recovery. The LOD and LOQ indicated the excellent sensitivity of the method. The robustness was testified by the modification of four different parameters, and the differences among each parameter were all less than 2%. Conclusion: qNMR offers a fast, reliable, and accurate
method of identifying and quantifying danshensu, lithospermic acid, rosmarinic acid, and salvianolic acid B in fresh SMB root extracts.

As the main bioactive component of Chinese herbal medicine Danshen, salvianolic acid B (Sal B, or lithospermic acid B) was observed to maintain the viability of mesenchymal stem cells (MSCs) treated by Fenton's reagent in the study. Interestingly, at a higher concentration, Sal B could even increase the viability rate to 175.1%. In mechanistic analysis experiments, Sal B was found to resist DNA destruction by •OH radical, scavenge various radicals in vitro , reduce Cu 2+ → Cu + , chelate Fe 2+ to yield an absorption maximum at 710 nm. Based on these results, we concluded that, (1) Sal B can not only protect MSCs against •OH-induced damages, but also promote their proliferation. This extraordinary capacity makes Sal B an ideal candidate in MSCs transplantation especially when MSCs are polluted by iron-overload or other oxidative stress factors and, can partly be responsible for the versatile properties of Sal B in pharmacology. The possible mechanisms of its protective effect are hypothesized to include Fe 2+ chelating, and direct radical scavenging which is involved in electron transfer (ET) or hydrogen atom transfer (HAT) from the catechol moieties. Its proliferation-promoting effect is presumed to be from its ester group, carboxylic group, or benzofuran ring.

In patients with diabetic wounds, wound healing is impaired due to the presence of persistent oxidative stress, an altered inflammatory response, and impaired angiogenesis and epithelization. Salvianolic acid B (SAB), which is derived from the Chinese medicinal plant Salvia miltiorrhiza , has been found to exhibit antioxidant, anti-inflammatory, and proangiogenic effects. Previous studies have used 3D bioprinting technology incorporating sodium alginate (SA) and gelatin (Gel) as basic biomaterials to successfully produce artificial skin. In the current study, 3D bioprinting technology was used to incorporate SAB into SA-Gel to form a novel SAB-SA-Gel composite porous scaffold. The morphological characteristics, physicochemical characteristics, biocompatibility, and SAB release profile of the SAB-SA-Gel scaffolds were evaluated in vitro. In addition, the antioxidant, anti-inflammatory, and proangiogenic abilities of the SAB-SA-Gel scaffolds were evaluated in cells and in a rat model. Analysis demonstrated that 1.0 wt% (the percentage of SAB in the total weight of the solution containing SA and Gel) SAB-SA-Gel scaffolds had strong antioxidant, anti-inflammatory, and proangiogenic properties both in cells and in the rat model. The 1.0% SAB-SA-Gel scaffold reduced the expression of tumor necrosis factor-α, interleukin-6, and interluekin-1β and increased the expression of transforming growth factor-β. In addition, this scaffold removed excessive reactive oxygen species by increasing the expression of superoxide dismutase, thereby protecting fibroblasts from injury. The scaffold increased the expression of vascular endothelial growth factor and platelet/endothelial cell adhesion molecule-1, accelerated granulation tissue regeneration and collagen deposition, and promoted wound healing. These findings suggest that this innovative scaffold may have promise as a simple and efficient approach to managing diabetic wound repair.

Background: Danshen (DS), the dry root ofSalvia miltiorrhizaBge., has been used in traditional Chinese medicine (TCM) for many years to promote blood circulation and to inhibit thrombosis. However, the active ingredients responsible for the anti-thrombotic effect and the underlying mechanisms are yet to be fully elucidated. Methods: Molecular docking was used to predict the active ingredients in DS and their potential targets by calculating the scores of docking between DS ingredients and thrombosis-related proteins. Then, a chemical-induced zebrafish thrombosis model was applied to confirm their anti-thrombotic effects. Result: The molecular docking results indicated that compared to the control ligand, higher docking scores were observed for several compounds in DS, among which salvianolic acid B (SAB), lithospermic acid (LA), rosmarinic acid (MA), and luteolin-7-O-β-d-glucoside (LG) could attenuate zebrafish caudal vein thrombosis and recover the decrease in heart red blood cells (RBCs) in a dose-dependent manner. Conclusions: Our study showed that it is possible to screen the potential active components in natural products by combining the molecular docking method and zebrafish in vivo model.Keywords:zebrafish;molecular docking;salvianolic acid B;rosmarinic acid;lithospermic acid;luteolin-7-O-β-d-glucoside;anti-thrombotic effects

Atherosclerosis (AS) is a chronic cardiovascular disease characterized by the accumulation of excess lipids within arterial walls. Since oxidative stress is one of the key drivers in its pathogenesis, antioxidative therapy serves as a promising strategy for AS treatment. Despite the potent antioxidant properties of polyphenolic salvianic acid A (SAA) and salvianolic acid B (SAB), clinical application is limited by their short half-life, insufficient target selectivity, and poor chemical stability. To overcome these limitations, we developed a biomimetic platelet membrane-coated polyphenol–cerium dioxide nanozyme complex (SS-CeO2@PLTM) as a broad-spectrum antioxidative system for comprehensive AS treatment. The SS-CeO2@PLTM was constructed by conjugating SAA and SAB on the surface of cerium dioxide via a one-pot method, followed by surface coating with a biomimetic platelet membrane. Systematic characterization using UV–vis spectroscopy, Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy-energy dispersive X-ray spectroscopy (TEM-EDS) elemental mapping analysis, Forster resonance energy transfer (FRET), molecular simulations, and pH-responsive release assays validated the successful synthesis and pH-responsive drug release behavior of SS-CeO2@PLTM. It was also found that SS-CeO2@PLTM exhibited broad-spectrum antioxidant activities, effectively scavenging superoxide anions, DPPH, H2O2, and intracellular reactive oxygen species (ROS) while enhancing hepatic SOD and GSH activities. Further cellular uptake and in vivo targeting assays confirmed their specific targeting for atherosclerotic plaques. SS-CeO2@PLTM demonstrated great efficiency in attenuating oxidative stress, inhibiting lipid uptake and lipid accumulation, mediating cholesterol efflux, and inhibiting inflammatory factor (IL-1β, IL-6, and TNF-α) secretion in RAW264.7 cells. We also found that SS-CeO2@PLTM exhibited improved lipid metabolism and diminished plaque area in apoE–/– mice via attenuating oxidative stress and NF-κB-mediated inflammation. Furthermore, biosafety was verified via hemolysis and in vivo safety tests. This study is the first to reveal the superior efficacy of the PLTM-based nanozyme complex in targeted AS therapy, offering a paradigm shift for multifactorial cardiovascular disease management.

The cellular and tissue damage induced by oxidative stress (OS) contribute to a variety of human diseases, which include gastrointestinal diseases. Salvianolic acid B (Sal B), which is a natural polyphenolic acid in Salvia miltiorrhiza , exhibits prominent antioxidant properties. However, its precise function and molecular mechanisms in protecting normal intestine epithelium from OS-induced damage are still poorly defined. In this study, we tried to clarify this relationship. Here, we found Sal B addiction in the rat intestinal epithelial cell, IEC-6, prevented H 2 O 2 -induced cell viability decrease and apoptosis induction, ameliorated H 2 O 2 -induced intestinal epithelial barrier dysfunction and mitochondrial dysfunction, and suppressed H 2 O 2 -induced production of ROS to varying degrees, ranging from 10% to 30%. Moreover, by employing an ischemia reperfusion model of rats, we also discovered that Sal B treatment reversed ischemia and a reperfusion-caused decrease in villus height and crypt depth, decreased proliferation of enterocytes, and increased the apoptotic index in the jejunum and ileum. Mechanistically, Sal B treatment up-regulated the phosphorylated level of Akt and GSK3β in enterocytes in vitro and in vivo , and PI3K inhibitor LY294002 treatment abrogated the protective effects of Sal B. Meanwhile, the inactivation of GSK3β reversed the oxidative stress-induced apoptosis and mitochondrial dysfunction in IEC-6 cells. Together, our results demonstrated that the damage of intestinal epithelial cells in in vitro and in vivo models were both attenuated by Sal B treatment, and such antioxidant activity might very possibly be attributed to the activation of Akt/GSK3β signaling.

Danqi tablet composed of the dried roots of Salvia miltiorrhiza and Panax notoginseng is a well-known Chinese patent medicine commonly used for the treatment of cardio-cerebrovascular diseases such as coronary heart disease and myocardial ischemia. Numerous chemical constituents belonging to S. miltiorrhiza and P. notoginseng were detectable in Danqi tablet. Here, we established and validated a rapid and sensitive ultra-performance liquid chromatography coupled with triple quadrupole mass spectrometry method for simultaneous quantification of 23 components in Danqi tablet and then successfully applied to assay 12 batches of samples from ten manufacturers. Our results demonstrated that the contents of 23 components in 12 batches of Danqi tablets varied significantly and their quality indeed existed differently based on the principal component analysis. According to the quantitative data and the loading plot of principal component analysis, five abundant compounds in Danqi tablet were selected as characteristic chemical markers possibly responsible for the quality assessment. Among them, salvianolic acid B and ginsenoside Rg 1 were further chosen to be combined at 2:5 ratio to evaluate the anti-thrombotic activity on phenylhydrazine-induced zebrafish heart thrombosis model. Expectedly, this component combination increased the heart red blood cells intensity compared with the model group and the median effective concentration was 123.4 µg/mL, suggestive of its well anti‑thrombotic effect. This study contributed to the quantitative evaluation of Danqi tablet and indicated the combination of salvianolic acid B and ginsenoside Rg 1 may be capable of reflecting the effect of Danqi tablet, thereby providing a reference for further investigations on the improvement of quality control and clinical application of Danqi tablet.

The aim of this study was to develop novel multiple agents loaded poly ( d , l -lactide-co-glycolide acid) (PLGA) nanoparticles (NPs) and evaluate their potential for brain delivery via inner ear administration. PLGA NPs loaded with salvianolic acid B (Sal B), tanshinone IIA (TS IIA) and panax notoginsenoside (PNS) were prepared by double emulsion/solvent evaporation method. It was observed that optimized NPs displayed satisfactory encapsulation efficiency and desired sustained-release characteristics. NPs following intratympanic administration (IT) in guinea pigs greatly improved drug distribution within the inner ear, cerebrospinal fluid (CSF) and brain tissues compared with intravenous administration (IV). Pharmacodynamic studies demonstrated that NPs following IT markedly inhibited oxidizing reactions and protected the brain from cerebral ischemia reperfusion (I/R) injury by upregulating superoxide dismutase (SOD) activity both in serum and brain tissues, simultaneously significantly reducing the levels of malondialdehyde (MDA) and nitric oxide synthase (NOS). Moreover intratympanic delivery did not cause injury of cochlear function by preliminary study on the toxicity. These findings suggested that PLGA NPs-based delivery system via inner ear administration was a promising candidate to brain delivery for the treatment of brain diseases.

Background Osteogenic differentiation of human periodontal ligament cells (hPDLCs) is crucial for regenerate periodontal tissues. In this study, we investigated the function of salvianolic acid B (Sal B) in osteogenesis of hPDLCs. Methods HPDLCs were isolated from healthy third molar roots. HPDLCs at passage 3 were identified by morphological observation and immunohistochemistry of vimentin . The viability of hPDLCs incubated with Sal B at concentrations of 0μM, 0.1μM, 0.5μM, 1μM and 5μM were measured by CCK-8 assay. To evaluate the effect of Sal B on osteogenic differentiation of hPDLCs, the alkaline phosphatase (ALP) activity, osteogenic differentiation markers, and mineralized nodules were determined by ALP kit, qRT-PCR and alizarin red S staining, respectively. To confirm the function of Sal B in hPDLCs involved in Wnt/β-catenin signaling pathway , hPDLCs were incubated with Sal B or co-incubated with Sal B and DKK-1 (a inhibitor of Wnt/β-catenin). The levels of Wnt/β-catenin signaling pathway and osteogenic differentiation-associated indicators were then determined. Results HPDLCs showed a typical fibroblast-like and spindle-shaped, with vimentin-positive. The viability of hPDLCs had no obvious change with stimulation of Sal B at various doses. Sal B promoted the increase of ALP activity, osteogenic differentiation markers levels, mineralized nodules and activation of Wnt/β-catenin signaling pathway, and DKK-1 could block those effects of Sal B on hPDLCs. Conclusion Sal B promoted osteogenesis of hPDLCs through Wnt/β-catenin signaling pathway, which providing a potential drug for periodontitis treatment .
