Salvianolic acid B protects against pulmonary fibrosis by attenuating stimulating protein 1-mediated macrophage and alveolar type 2 cell senescence. Phytother Res 2024; 38:620-635. [PMID: 37953063 DOI: 10.1002/ptr.8070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Revised: 10/19/2023] [Accepted: 10/31/2023] [Indexed: 11/14/2023]
Abstract
Idiopathic pulmonary fibrosis (IPF), as the most common idiopathic interstitial pneumonia, is caused by a complex interaction of pathological mechanisms. Interestingly, IPF frequently occurs in the middle-aged and elderly populations but rarely affects young people. Salvianolic acid B (SAB) exerts antioxidant, antiinflammatory, and antifibrotic bioactivities and is considered a promising drug for pulmonary disease treatment. However, the pharmacological effects and mechanisms of SAB on cellular senescence of lung cells and IPF development remain unclear. We used bleomycin (BLM)-induced pulmonary fibrosis mice and different lung cells to investigate the antisenescence impact of SAB and explain its underlying mechanism by network pharmacology and the Human Protein Atlas database. Here, we found that SAB significantly prevented pulmonary fibrosis and cellular senescence in mice, and reversed the senescence trend and typical senescence-associated secretory phenotype (SASP) factors released from lung macrophages and alveolar type II (AT2) epithelial cells, which further reduced lung fibroblasts activation. Additionally, SAB alleviated the epithelial-mesenchymal transition process of AT2 cells induced by transforming growth factor beta. By predicting potential targets of SAB that were then confirmed by chromatin immunoprecipitation-qPCR technology, we determined that SAB directly hampered the binding of transcription factor stimulating protein 1 to the promoters of SASPs (P21 and P16), thus halting lung cell senescence. We demonstrated that SAB reduced BLM-induced AT2 and macrophage senescence, and the subsequent release of SASP factors that activated lung fibroblasts, thereby dual-relieving IPF. This study provides a new scientific foundation and perspective for pulmonary fibrosis therapy.

Eur J Pharmacol 2023:175812. [PMID: 37245856 DOI: 10.1016/j.ejphar.2023.175812] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 05/08/2023] [Accepted: 05/25/2023] [Indexed: 05/30/2023]
Abstract
Diabetic nephropathy (DN) is a major cause of renal failure and urgently necessitates new therapeutic strategies. Magnesium lithospermate B (MLB) showed a good protective effect on kidney injure by oral administration, despite its extremely low bioavailability. The current study aimed to investigate its gut microbiota-targeted mechanism to explain the paradoxical properties of pharmacodynamics and pharmacokinetics. Here we show that MLB alleviated DN by recovering the dysfunction of gut microbiota and their associated metabolites in colon content, such as short-chain fatty acids and amino acids. Moreover, MLB significantly decreased uremic toxin levels in plasma, especially the p-cresyl sulfate. We further discovered that MLB could affect the metabolism of p-cresyl sulfate by suppressing the formation of its intestinal precursors, i.e. the microbiota-mediated conversion from 4-hydroxyphenylacetate to p-cresol. In addition, the inhibition effects of MLB were confirmed. MLB and its metabolite danshensu exhibited inhibitory effects on p-cresol formation mediated by three strains belonging to the genus Clostridium, Bifidobacterium, and Fusobacterium, respectively. Meanwhile, MLB decreased the levels of p-cresyl sulfate in plasma and p-cresol in feces caused by rectal administration of tyrosine in mice. To summarize, the results indicated that MLB ameliorated DN through modulating gut microbiota-associated p-cresyl sulfate metabolism. Together, this study provides new insights on the microbiota-targeted mechanism of MLB in intervening DN and a new strategy in lowering plasma uremic toxins by blocking the formation of their precursors in intestine.

Abstract
Salvia is widely recognized for its therapeutic potential. However, the biological relevance of some species remains unknown, namely Salvia cacaliifolia Benth. Therefore, the aim of this study is to unveil the chemical composition and relevant properties to its essential oil (EO). The EO was characterized by GC and GC-MS and its antifungal effect was evaluated according to the CLSI guidelines on dermatophytes and yeasts. The anti-inflammatory potential was assessed on lipopolysaccharide-stimulated macrophages, by assessing the production of nitric oxide (NO) and the effect on the protein levels of two key pro-inflammatory enzymes, iNOS and COX-2 by western blot analysis. Wound healing capacity was determined using the scratch wound healing assay, and the anti-aging potential was assessed by evaluating the senescence marker β-galactosidase. The EO was mainly characterized by γ-curcumene, β-bisabolene, bicyclogermacrene and curzerenone. It is effective in inhibiting the growth of dermatophytes and C. neoformans. The EO significantly decreased iNOS and COX-2 protein levels and concomitantly reduced NO release. Additionally, it demonstrated anti-senescence potential and promoted wound healing. Overall, this study highlights relevant pharmacological properties of the EO of Salvia cacaliifolia, which should be further explored envisaging the development of sustainable, innovative, and environmentally friendly skin products.

Abstract
As the current treatment of chronic kidney disease (CKD) is limited, it is necessary to seek more effective and safer treatment methods, such as Chinese herbal medicines (CHMs). In order to clarify the modern theoretical basis and molecular mechanisms of CHMs, we reviewed the knowledge based on publications in peer-reviewed English-language journals, focusing on the anti-inflammatory, antioxidative, anti-apoptotic, autophagy-mediated and antifibrotic effects of CHMs commonly used in kidney disease. We also discussed recently published clinical trials and meta-analyses in this field. Based on recent studies regarding the mechanisms of kidney disease in vivo and in vitro, CHMs have anti-inflammatory, antioxidative, anti-apoptotic, autophagy-mediated, and antifibrotic effects. Several well-designed randomized controlled trials (RCTs) and meta-analyses demonstrated that the use of CHMs as an adjuvant to conventional medicines may benefit patients with CKD. Unknown active ingredients, low quality and small sample sizes of some clinical trials, and the safety of CHMs have restricted the development of CHMs. CHMs is a potential method in the treatment of CKD. Further study on the mechanism and well-conducted RCTs are urgently needed to evaluate the efficacy and safety of CHMs.

Abstract
BACKGROUD Magnesium lithospermate B (MLB) is a major bioactive component of Slavia miltiorrhiza, which has been widely used in heart diseases on account of its anti-inflammatory, anti-oxidative, anti-proliferative and anti-fibrotic properties. Substance P(SP) is a small molecule neuropeptide, which was secreted much more during heart failure, and has an obvious function of immune enhancement and inflammation induction. This study aimed to investigate the protective effects of MLB on pulmonary artery banding (PAB) induced right ventricular (RV) dysfunction. METHODS The mouse model of PAB was established. The mice were intraperitoneal (IP) injection treated with MLB (10 mg kg-1·d-1) for 4 weeks and p38 mitogen-activated protein kinase (MAPK) activator was given at the same time. Echocardiography were performed on day 28. Then the hearts were harvested, and substance P (SP), inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β) and cardiac fibrosis were detected. The macrophages and fibroblasts were stimulated by SP separately, and then treated with MLB as well as p38MAPK activator. The inflammatory cytokines from macrophage, the proliferation and fibrosis of cardiac fibroblasts were measured. The expression of p38MAPK proteins were confirmed by immunoblotting. FINDINGS MLB preserved RV ejection fraction (EF), FS, RV/(LV + septum), HW/BW index and blunted RV inflammation as well as fibrosis. Phosphorylated-p38 (p-p38) MAPK was up-regulated, which was partially reversed by MLB treatment. However, p38MAPK activator abolished the effects of MLB on RV dysfunction, suggesting a key role of p38MPAK pathway in the effects of MLB reversing RV dysfunction. In external experiment, MLB reversed the increase of inflammatory cytokines from macrophage, the proliferation and fibrosis of cardiac fibroblasts which was simulated by SP. In accordance with in vivo study, p38MAPK activator abolished the effects of MLB on macrophage as well as fibroblasts. INTERPRETATION MLB improves PAB induced right ventricular remodeling by alleviating inflammation via p38MAPK pathway. Thus, MLB may offer the therapeutic potential for the patients of RV dysfunction.

Abstract
Pulmonary arterial hypertension (PAH) is a progressive disease characterized by vascular remodeling leading to elevation of pulmonary artery pressure, right ventricular hypertrophy, and death. Currently, there are no cure exists for PAH. Magnesium lithospermate B (MLB) is the major component of Salvia przewalskii water extracts with treating angina and cardiovascular damage, anti-inflammation, anti-oxidation and anti-apoptosis. However, the effects of MLB on PAH still unclear. This study we investigated the efficacy of MLB in the hypobaric hypoxia-induced rat model of PAH. The results showed that MLB relieved mean pulmonary arterial pressure (mPAP) and right ventricular hypertrophy index (RVHI). Meanwhile, MLB significantly reduced pulmonary vascular remodeling. Additionally, MLB inhibited hypobaric hypoxia-induced α-smooth muscle actin (α-SMA) expression, cell apoptosis, and α-SMA and von Willebrand factor (vWF) co-expression in lung, suggesting that MLB could inhibit hypobaric hypoxia-induced endothelial-to-mesenchymal transition (EndMT). Furthermore, after treatment with MLB, the expression of hypoxia inducible factor-1α (HIF-1α), nuclear factor-kappa B (NF-κB), monocyte chemoattractant protein-1 (MCP-1), proliferating cell nuclear antigen (PCNA), cyclin-dependent kinase 4 (CDK4), CyclinD1, RhoA, rho-associated protein kinase 1 (ROCK1) and ROCK2 was decreased. Further, CHK1, PIM1, STK6, LKHA4, PDE5A, BRAF1, PLK1, AKT1, PAK6, PAK7 and ELNE may be the potential targets of MLB. Taken together, our findings suggest that MLB ameliorates hypobaric hypoxia-induced PAH by inhibiting EndMT in rats, and has potential value in the preventment and treatment of PAH.

Abstract
Salvia miltiorrhiza, known as Danshen in Chinese, has been widely used to treat cardiovascular diseases in China. Tanshinone I (Tan I) and cryptotanshinone (CST) are the lipid-soluble and effective components from Salvia miltiorrhiza. However, the molecular mechanism of Tan I and CST for treating inflammation is still not known. Therefore, this study was designed to use network pharmacology-based strategy to predict therapeutic targets of Tan I and CST against inflammation, and further to investigate the pharmacological molecular mechanism in vitro. Inflammation targets were identified and followed by acquisition of verified targets of Tan I and CST. After constructing target-functional protein interaction network of Tan I and CST against inflammation, the core therapeutic targets of Tan I and CST against inflammation were obtained. Further, pathway enrichment analyses were performed on core therapeutic targets to evaluate key signaling pathways of Tan I and CST against inflammation. As revealed in network pharmacology analysis, 8 key hub targets for Tan I and CST against inflammation were identified, respectively: JUN, VEGFA, IL-6, TNF, MAPK8, CXCL8, and PTGS2 for Tan I, while STAT3, AKT1, CCND1, MAPK14, VEGFA, ESR1, MAPK8 and AR for CST. Pathway enrichment analysis by DAVID database indicated that Tan I and CST principally regulated the inflammation-associated pathway, such as TLR, JAK-STAT signaling pathway, focal adhesion, apoptosis, mTOR signaling pathway. In vitro, we found that both Tan I and CST exerts significantly effect on LPS stimulated NO secretion and iNOS expression in macrophages. Taken together, our data elucidate that anti-inflammatory pharmacological activities of Tan I and CST may be predominantly related to inhibition of TLR signaling pathway and regulating iNOS synthesis. These findings highlight the predicted therapeutic targets may be potential targets of Tan I and CST for anti-inflammation treatment.

BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 19:107. [PMID: 31118021 PMCID: PMC6530021 DOI: 10.1186/s12906-019-2524-6] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Accepted: 05/15/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND Excessive activation of NLRP3 inflammasome and down-regulation of Sirt1/Smad3 deacetylation pathway play a significant role in the evolution of renal fibrosis. In China, it has been well known that Chinese herbal medicine is markedly effective in treating chronic kidney disease (CKD). Shen Shuai IIRecipe (SSR) has been used clinically for more than 20 years and has been confirmed to be effective in improvements of renal function and fibrosis. However, the specific mechanisms under the efficacy require further research. The purpose of this study was to evaluate whether SSR could alleviate renal injury and fibrosis by regulating NLRP3 inflammasome and Sirt1/Smad3 deacetylation pathway. METHODS Four weeks after 5/6 ablation/infarction (A/I) surgery, Sprague-Dawley rats were randomly divided into the following groups: sham operation group, 5/6 (A/I) group, 5/6 (A/I) + SSR group, and 5/6 (A/I) + Losartan group (5/6 (A/I) + Los). After 8 weeks intervention,we mainly assessed the severity of renal injury and fibrosis along with the activation of NLRP3 inflammasome and Sirt1/Smad3 deacetylation pathway. RESULTS SSR significantly attenuated renal injury and fibrosis in the remnant kidneys. In addition, we found that SSR effectively inhibited activation of NLRP3/ASC/Caspase-1/IL-1βcascade, decreased inflammatory infiltration and up-regulated Sirt1/Smad3 deacetylation pathway. CONCLUSIONS SSR could contribute to renal protection by inhibiting the activation of NLRP3 inflammasome and, furthermore, strengthen the antifibrotic effects by up-regulating Sirt1/Smad3 deacetylation pathway in 5/6 renal (A/I) model.

Exp Ther Med 2019; 18:163-171. [PMID: 31258650 PMCID: PMC6566092 DOI: 10.3892/etm.2019.7556] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2017] [Accepted: 11/03/2017] [Indexed: 12/27/2022] Open
Abstract
The present study aimed to explore the potential of combined treatment with mesenchymal stem cells (MSCs) and danshen for angiogenesis and bone regeneration in a rabbit model of avascular necrosis of femoral head (ANFH). A rabbit model of ANFH was established using the Shwartzman reaction with methylprednisolone and Escherichia coli endotoxin injection. Magnetic resonance imaging (MRI) and histopathological examination were used to evaluate the rabbit model of ANFH. The rabbits were randomly divided into the danshen group, the MSCs group, the danshen combined with MSCs group and the model group (treated with physiological saline). The expression level of monocyte chemoattractant protein-1 (MCP-1) and stromal cell-derived factor-1 (SDF-1) were determined by reverse transcription polymerase chain reaction (RT-PCR). The expression level of bone morphogenetic protein-2 (BMP-2) and vascular endothelial growth factor (VEGF) were detected by immunofluorescence and the mRNA expression of BMP-2 and VEGF were detected by RT-PCR. Typical osteonecrosis occurred in the rabbit model of ANFH, which indicated that the model was successfully established. MCP-1 and SDF-1 were significantly increased in the model group compared with the normal group (P<0.05). Following the administration of MSCs and Salvia miltiorrhiza (danshen), MSCs labeled with 5-bromo-2-deoxyuridine were observed to be gathered in the necrotic area. The increased migration of MSCs to the necrotic area may be due to the upregulated expression of the chemokines MCP-1 and SDF-1. ANFH treated with danshen combined with MSCs may promote revascularization by increasing the expression of VEGF and BMP-2 in the femoral head, promoting re-ossification and revascularization. Danshen combined with the transplantation of MSCs may be regarded as a novel therapy for the treatment of ANFH in a clinical setting.

Magnesium lithospermate B prevents phenotypic transformation of pulmonary arteries in rats with hypoxic pulmonary hypertension through suppression of NADPH oxidase. Eur J Pharmacol 2019; 847:32-41. [PMID: 30659826 DOI: 10.1016/j.ejphar.2019.01.020] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2018] [Revised: 01/08/2019] [Accepted: 01/15/2019] [Indexed: 02/06/2023]
Abstract
Magnesium lithospermate B (MLB) shows multiple biological activities including anti-oxidation and anti-proliferation in various diseases. However, the function of MLB in pulmonary arterial hypertension (PAH) is still unknown. This study aims to investigate the effect of MLB on hypoxia-induced phenotypic transformation of pulmonary arterial smooth muscle cells (PASMCs) and the underlying mechanisms. SD rats (or PASMCs) were exposed to 10% O2 for 3 weeks (or 3% O2 for 48 h) along with MLB or NADPH oxidase (NOX) inhibitor intervention. The effects of MLB on hemodynamics, pulmonary vascular remodeling and phenotypic transformation of PASMCs were observed first. Then, its effects on the protein levels of NOX (NOX2 and NOX4), ERK and p-ERK were examined. The results showed that MLB prevented the elevation in right ventricular systolic pressure and the increase in ratio of wall thickness to vessel external diameter of pulmonary arteries in PAH rats, and attenuated phenotypic transformation of PASMCs (decrease in α-smooth muscle actin while increase in osteopontin), accompanied by downregulation of NOX (NOX2 and NOX4) protein levels, decrease of ROS and H2O2 production, and suppression of the phosphorylation of ERK. NOX inhibitor (VAS2870) achieved similar results to that of MLB did in the hypoxia-treated PASMCs. Based on the observations, we conclude that MLB is able to prevent phenotypic transformation of pulmonary arteries in hypoxic PAH rats through suppression of NOX/ROS/ERK pathway, and MLB might have the potentials in PAH therapy.

Mechanism of Action of Magnesium Lithospermate B against Aging and Obesity-Induced ER Stress, Insulin Resistance, and Inflammsome Formation in the Liver. Molecules 2018; 23:molecules23092098. [PMID: 30134566 PMCID: PMC6225288 DOI: 10.3390/molecules23092098] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Revised: 08/17/2018] [Accepted: 08/20/2018] [Indexed: 01/25/2023] Open
Abstract
Magnesium lithospermate B (MLB) is the biologically active compound of the water-soluble fraction of Salvia miltiorrhiza. Magnesium lithospermate B exhibits various biological functions, including antidiabetic, neuroprotective, and antioxidant effects. However, its beneficial effects on insulin sensitivity and related signaling pathways in the liver need to be elucidated. Our previous study reported that MLB is a PPARβ/δ agonist in fibroblasts. Because insulin-sensitizing and anti-inflammatory effects of PPARβ/δ has been reported in the liver, we investigated whether MLB has a beneficial effect on insulin-, ER stress- and inflammasome-related signaling in the livers of aging and obese animal models. Western blotting and protein-ligand docking simulation showed that MLB activated PPARβ/δ and improved glucose tolerance in the livers of aging and obese animal models. MLB supplementation ameliorated aging or obesity-induced disruption of insulin signaling in the liver. Consistently, aging and obesity-induced increase in the protein levels of a gluconeogenic phosphoenolpyruvate carboxykinase was decreased by MLB. When molecular signaling pathways related to insulin signaling were examined in the liver, MLB supplementation suppressed ER stress- and inflammasome-related signaling molecules induced by aging and obesity. These results suggest that MLB may improve insulin resistance in the liver at least partially by suppressing ER stress and inflammasome formation in aging and obese animal models.

Abstract
Chronic kidney disease (CKD) is a significant worldwide healthcare problem. Regardless of the initial injury, renal fibrosis is the common final pathway leading to end stage renal disease. Although the underlying mechanisms are not fully defined, evidence indicates that besides inflammation, oxidative stress plays a crucial role in the etiology of renal fibrosis. Oxidative stress results from an imbalance between the production of free radicals that are often increased by inflammation and mitochondrial dysfunction, and reduced anti-oxidant defenses. Several studies have demonstrated that oxidative stress may occur secondary to activation of transforming growth factor β1 (TGF-β1) activity, consistent with its role to increase nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (Nox) activity. A number of other oxidative stress-related signal pathways have also been identified, such as nuclear factor erythroid-2 related factor 2 (Nrf2), the nitric oxide (NO)-cyclic guanosine monophosphate (cGMP)-cGMP-dependent protein kinase 1-phosphodiesterase (cGMP-cGK1-PDE) signaling pathway, and the peroxisome proliferator-activated receptor gamma (PPARγ) pathway. Several antioxidant and renoprotective agents, including cysteamine bitartrate, epoxyeicosatrienoic acids (EETs), and cytoglobin (Cygb) have demonstrated ameliorative effects on renal fibrosis in preclinical or clinical studies. The mechanism of action of many traditional Chinese medicines used to treat renal disorders is based on their antioxidant properties, which could form the basis for new therapeutic approaches. This review focuses on the signaling pathways triggered by oxidative stress that lead to renal fibrosis and provides an update on the development of novel anti-oxidant therapies for CKD.

Abstract
BACKGROUND Hepatorenal syndrome (HRS) is a life-threatening complication of end-stage liver diseases. It has been reported that traditional Chinese medicine (TCM) may improve liver function, delay disease progression, alleviate symptoms, and improve quality of life in HRS patients. The study aims to systematically review the efficacy of TCM for the treatment of HRS. METHODS Publications were searched electronically from China National Knowledge Infrastructure (CNKI), Wanfang, VIP, PubMed, and EMBASE databases. Odds ratio (OR) and standardized mean difference (SMD) with 95% confidence interval (CI) were calculated. Heterogeneity was assessed. The Cochrane Collaboration's tool was used to assess the risk of bias. RESULTS Fourteen randomized controlled trials involving 788 patients with HRS were included. Random generation sequence was reported in only two studies. Blinding was not used in any study. Compared to conventional treatment without TCM, TCM led to a significant survival benefit during hospitalization (OR: 0.18; 95% CI: 0.08-0.39; P<0.0001), a significantly higher complete response (OR: 3.20; 95% CI: 2.06-4.97; P<0.00001), and a significantly lower no response (OR: 0.20; 95% CI: 0.14-0.30; P<0.00001). Partial response was not significantly different between the two groups (OR: 1.39; 95% CI: 0.90-2.15; P=0.14). Regardless of TCM, blood urea nitrogen and abdominal circumference were significantly decreased, and urine volume was significantly increased after treatment. Compared to conventional treatment without TCM, TCM led to a significantly lower serum creatinine, blood urea nitrogen, bilirubin, plasma ammonia, and abdominal circumference and significantly higher urine volume after treatment. There was significant heterogeneity. CONCLUSIONS TCM might have a better survival and a higher complete response in patients with HRS. However, the quality of published studies was unsatisfactory.

MEDICINES 2017; 4:medicines4040085. [PMID: 29160857 PMCID: PMC5750609 DOI: 10.3390/medicines4040085] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Revised: 11/15/2017] [Accepted: 11/15/2017] [Indexed: 01/09/2023]
Abstract
Background: This study investigated the combination effects of the Danshen and Sanqi herb pair on angiogenesis in vitro. Methods: Nine combination ratios of Danshen-Sanqi extracts (DS-SQ) were screened for their angiogenic effects in the human vascular endothelial EAhy 926 cell line via cell proliferation, cell migration and tube formation activities against the damage to the cells exerted by DL-homocysteine (Hcy) and adenosine (Ado). The type of interaction (synergistic, antagonistic, additive) between Danshen and Sanqi was analyzed using combination index (CI) and isobologram models. The angiogenic activities of key bioactive compounds from Danshen and Sanqi were tested in the same models. Results: DS-SQ ratios of 2:8 and 3:7 (50-300 µg/mL) potentiated angiogenic synergistic effects (CI < 1) in all three assays. The observed wound healing effects of DS-SQ 2:8 was significantly attenuated by phosphatidylinositol-3 kinases (PI3K), mitogen-activated protein kinase (MEK) and extracellular signal-regulated kinases (ERK) inhibitors which inferred the potential mechanistic pathways. Out of all the tested compounds, Notoginsenoside R1 from Sanqi exhibited the most potent bioactivity in cell proliferation assay. Conclusions: This study provides scientific evidence to support the traditional use of the Danshen-Sanqi combination for vascular disease, in particular through their synergistic interactions on previously unexamined angiogenic pathways.
