Naoxintong capsule for treating cardiovascular and cerebrovascular diseases: from bench to bedside. Front Pharmacol 2024; 15:1402763. [PMID: 38994201 PMCID: PMC11236728 DOI: 10.3389/fphar.2024.1402763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Accepted: 06/06/2024] [Indexed: 07/13/2024] Open
Abstract
Naoxintong Capsule (NXT), a renowned traditional Chinese medicine (TCM) formulation, has been broadly applied in China for more than 30 years. Over decades, accumulating evidences have proven satisfactory efficacy and safety of NXT in treating cardiovascular and cerebrovascular diseases (CCVD). Studies have been conducted unceasingly, while this growing latest knowledge of NXT has not yet been interpreted properly and summarized comprehensively. Hence, we systematically review the advancements in NXT research, from its chemical constituents, quality control, pharmacokinetics, to its profound pharmacological activities as well as its clinical applications in CCVD. Moreover, we further propose specific challenges for its future perspectives: 1) to precisely clarify bioactivities of single compound in complicated mixtures; 2) to evaluate the pharmacokinetic behaviors of NXT feature components in clinical studies, especially drug-drug interactions in CCVD patients; 3) to explore and validate its multi-target mechanisms by integrating multi-omics technologies; 4) to re-evaluate the safety and efficacy of NXT by carrying out large-scale, multicenter randomized controlled trials. In brief, this review aims to straighten out a paradigm for TCM modernization, which help to contribute NXT as a piece of Chinese Wisdom into the advanced intervention strategy for CCVD therapy.

Abstract
Seven undescribed tannins, namely gejaponin A-G, and one dehydrodigallic acid derivative 3,4-dihydroxy-5-(3,4,5-trihydroxy-1-ethoxycarbonyl phenoxy)benzoic acid, together with eighteen known polyphenols were isolated from the 95% ethanol extract of the aerial part of Geum japonicum Thunb. var. chinense F. Bolle. Their structures were elucidated on the basis of comprehensive analysis of UV, IR, NMR, HRMS, and CD spectroscopy experiments. To evaluate their bioactivities, sixteen major compounds were selected to intervene in hydrogen peroxide (H2O2)-induced oxidative damage on H9c2 rat cardiomyoblasts. Some compounds demonstrated high activity in this assay, of which, the known compounds 16 and 21 exhibited strong protective effects against H2O2-induced injury in H9c2 rat cardiomyoblasts, with a comparable cardioprotective activity as that of the positive control trimetazidine, thereby revealing cardioprotective activities from G. japonicum var. chinense.

Chem Biol Drug Des 2024; 103:e14440. [PMID: 38230784 DOI: 10.1111/cbdd.14440] [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: 05/10/2023] [Revised: 10/02/2023] [Accepted: 12/19/2023] [Indexed: 01/18/2024]
Abstract
Naoxintong capsule (NXT) is a clinical drug for the treatment of cardiovascular diseases, but its pharmacological mechanism against hypertension remains unclear. Data concerning the compounds and targets of NXT were obtained from the TCMSP and DrugBank, whereas data concerning hypertension-related genes were obtained from DisGeNET. The network was analyzed and established by STRING and Cytoscape, and function enrichment was analyzed by GO and KEGG analysis. Molecular docking was performed to analyze the interaction between ingredients and targets, cellular activity was evaluated by MTT assay, and RT-qPCR and western blot were used to evaluate the expressions of related genes. The results showed that 146 active therapeutic components can target hypertension-related genes, and we found that core genes were mainly involved in the metabolism of lipids, lipopolysaccharides, the inflammatory signaling pathway, and the oxidative stress pathway. In addition, there was high affinity between the components of NXT and targets of hypertension, where the former can increase cell viability and reduce the expressions of NOX4, MCP-1, BAX, TNF-α and IL-1β. Moreover, NXT inhibited the expressions of IL-6 and Fis1, as well as increased the expression of MCL-1. These results revealed the active compounds, hypertension targets, signaling pathways, and molecular mechanisms of NXT for treating hypertension, offering references for the clinical application of NXT and the treatment of hypertension.

Abstract
Heart failure (HF) is a complex clinical syndrome with impaired ventricular ability due to structural or functional cardiac disorders. A traditional Chinese formula named Xinshubao tablet (XSB) is reported to protect cardiomyocytes and decrease the risk of HF clinically; however, the underlying mechanism of XSB on decreasing HF risk is not elucidated yet. Therefore, our study aimed to investigate the therapeutic efficacy and underlying mechanism of XSB by using HF model rats and H9c2 cells with oxygen glucose deprivation. Echocardiographic and pathological features of animal experiment showed that XSB treatment effectively improved cardiac function and ameliorated myocardial injury after 4 weeks of treatment. Cellular experiments indicated that XSB pretreatment significantly inhibited apoptosis and increased mitochondrial energy metabolism. Furthermore, in vivo and in vitro experiments both demonstrated that XSB suppressed oxidative stress and inflammatory response. Our results further revealed that the potential protective mechanism of XSB was closely associated with the DCN/PPARα/PGC-1α/P300 signaling pathway. Our findings provide novel mechanistic insights for HF treatment and a pharmacological basis for the therapeutic application of XSB against cardiovascular disorders.

Abstract
Oxidative stress has recently been identified as an important mediator of cardiovascular diseases. The need to find efficient antioxidant molecules is essential in the disease's prevention. Therefore, the present study aimed to evaluate the potential of microalgae bioactive in protecting H9c2 cardiomyoblasts from H2O2-induced oxidative stress. Four microalgal species were investigated for their antioxidant capacity. A qualitative assessment of oxidative stress in H9c2 cardiomyoblasts stained with DCFH-DA, treated with the highly active microalgae extracts, was performed. The protein expression of total caspase-3 was also examined to investigate whether the extract protects H9c2 cardimyoblasts from H2O2-induced apoptosis. High antioxidant activity was observed for the hexanoic extracts after 10 days of cultivation. Asterarcys quadricellulare exhibited the highest antioxidant capacity of 110.59 ± 1.75 mg TE g-1 dry weight and was tested against H9c2 cardiomyoblasts, which were initially subjected to H2O2-induced oxidative stress. This hexanoic extract protected against H2O2 induced oxidative stress with a similar scavenging capacity as N-Acetylcysteine. Furthermore, total caspase-3 was increased following treatment with the hexanoic extract, suggesting that A. quadricellulare also had anti-apoptotic properties. The outcome of our study highlighted the possible use of the local A. quadricellulare strain QUCCCM10 as a natural, safe, and efficient antioxidant to prevent cardiovascular diseases.

Abstract
Background Vascular dementia (VaD) is the second most common form of dementia among the elderly. There is currently no unequivocal recommendation of an effective treatment option for VaD. Objective The purpose of this study was to evaluate the efficacy and safety of Naoxintong capsule (NXT) in the treatment of VaD patients. Methods We searched for randomized controlled trials (RCTs) published before September 2021 in PubMed, Embase, Web of Science, Cochrane Library, CNKI, VIP, and Wanfang databases. The trials assessed the efficacy and/or safety of NXT in treating patients with VaD. A meta-analysis was then performed using Stata 14.0 software. Results A total of 33 studies comprising 2,947 patients with VaD were included in this study. The meta-analysis revealed that NXT improved cognitive function in VaD patients, increased the mini-mental state examination (MMSE) score by 3.33 points (WMD = 3.33, 95% CI (2.72, 3.94)), the Montreal Cognitive Assessment (MoCA) score by 4.31 points (WMD = 4.31, 95% CI (2.72, 5.90)), and the Hasegawa dementia scale (HDS) by 2.71 points (WMD = 2.71, 95% CI (1.26, 4.17)). Furthermore, NXT significantly improved the daily lives of VaD patients, lowering the activities of daily living (ADL) score by 5.85 points (WMD = −5.85, 95% CI (−7.03, −4.66)). NXT improved the total effective rate (TER) (OR = 2.62, 95% CI (2.09, 3.29)) of the patients without increasing the occurrence of adverse events (AEs; OR = 0.72, 95% CI (0.43, 1.22)). Subgroup analysis revealed that whether NXT was used alone or in combination with western medicine, it could enhance the overall curative effect. Conclusions NXT may be an effective and safe treatment option for VaD. However, because of the limited number and quality of articles included, this study's findings need to be validated by additional high-quality, large-sample, and multicenter RCTs (Systematic Review Registration Number: PROSPERO; https://clinicaltrials.gov/ct2/show/CRD42021233199).

Abstract
Background: Naoxintong Capsule (NXT) is a formulated Traditional Chinese Medicine (TCM) widely applied in the treatment of cardiovascular and metabolic diseases, most of which are closely related to hyperlipidemia as a major risk factor. Given the current limited understandings to the role of gut microbiota in the lipid-lowering effect of NXT and other TCM products, this study investigated the regulation of gut microbiota and lipid metabolism by NXT, and their potential relationship. Methods: The chemical components of NXT were firstly analyzed with HPLC-MS method. In high fat diet (HFD)-fed rat models, as well as normal rats as control, the histopathological and biochemical changes of serum and liver were examined, including total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C). In addition, the gut microbiota community was analyzed using 16S rRNA sequencing technique, the fecal levels of gut microbiota related metabolites, including bile acids (BAs) and short chain fatty acids (SCFAs) were determined with HPLC-MS. The correlations of the clinical indicators and gut microbiota related indicators were then investigated statistically. Results: The results showed that NXT exerted potential preventive effect on hyperlipidemia. Specifically, NXT significantly reduced the body weight, TC, TG and LDL-C in serum, increased HDL-C in serum, reduced the TC and TG in liver, as well as protected liver. The body weight, serum lipid levels and liver function were all significantly alleviated. The gut microbiota of the HFD-fed rats was reconstituted with supplementation of NXT. The fecal levels of gut microbiota related metabolites, including BAs and SCFAs were also altered. The correlation between the gut microbiota and clinical/metabolomic parameters was then studied. As the result, the amount of propionic aicd, Firmicutes/Bacteroidetes ratio (F/B) and the relative abundance of Collinsella in feces are the most possibly potential therapeutic biomarkers of NXT. Conclusion: NXT was effective in regulation of gut microbiota and prevention of hyperlipidemia in HFD fed rats. The present work might provide novel insights into the anti-hyperlipidemia effect of TCM and afford new scientific evidence for clinical application of TCM.

Abstract
Retinal degenerative diseases are related to retinal injury because of the activation of the complement cascade, oxidative stress-induced cell death mechanisms, dysfunctional mitochondria, chronic neuroinflammation, and production of the vascular endothelial growth factor. Anti-VEGF therapy demonstrates remarkable clinical effects and benefits in retinal degenerative disease patients. Hence, new drug development is necessary to treat patients with severe visual loss. He xue ming mu (HXMM) tablet is a CFDA-approved traditional Chinese medicine (TCM) for retinal degenerative diseases, which can alleviate the symptoms of age-related macular degeneration (AMD) and diabetic retinopathy (DR) alone or in combination with anti-VEGF agents. To elucidate the mechanisms of HXMM, a quantitative evaluation algorithm for the prediction of the effect of multi-target drugs on the disturbance of the disease network has been used for exploring the specific pathology of HXMM and TCM precision positioning. Compared with anti-VEGF agents, the drug disturbance of HXMM on the functional subnetwork shows that HXMM reduces the network robustness on the oxidative stress subnetwork and inflammatory subnetwork to exhibit the anti-oxidation and anti-inflammation activity. HXMM provides better protection to ARPE-19 cells against retinal injury after H2O2 treatment. HXMM can elevate GSH and reduce LDH levels to exhibit antioxidant activity and suppress the expression of IL-6 and TNF-α for anti-inflammatory activity, which is different from the anti-VEGF agent with strong anti-VEGF activity. The experimental result confirmed the accuracy of the computational prediction. The combination of bioinformatics prediction based on the drug attack on network robustness and experimental validation provides a new strategy for precision application of TCM.

Abstract
CONTEXT Naoxintong capsule (NXT) is one of the most prevalent Traditional Chinese Medicine formulations in the treatment of coronary heart disease (CHD), yet the action of pharmacodynamic components remains unclear. OBJECTIVE To determine the basis by which pharmacodynamic components of NXT may be effective in the treatment of CHD. MATERIALS AND METHODS The protective effect of NXT (0.01-100 μg/mL) on 293 T and hy926 cells was determined by MTT assay for 24 h. Afterwards, to investigate the pharmacodynamic material basis of NXT in anti-inflammatory and antioxidant effects, based on previous UPLC/Q-TOF analysis, 293 T and hy926 cells were divided into control (treated with solvent), model (incubated with TNF-α, LPS or H2O2), intervention (treated with UPLC components) and positive groups. After 24 h of treatment, all cells were tested to verify the screening results. MOE software was applied to dock bioactive compounds with phosphoinositide 3-kinase (PI3K), then the protein expression and phosphate levels were determined by western blotting. RESULTS NXT could significantly inhibit the expression of NF-κB, MMP-9 and NO in cells with IC50 values of 0.1178, 0.1182 and 0.1094 μg/mL. Based on the screening results, six components of NXT were identified (calycosin, ferulic acid, salvianolic acid B, ononin, salvianolic acid E, and salvianolic acid F) which can inhibit NF-κB, MMP-9, and NO simultaneously, while exerting cytoprotective effects by inhibiting the activation of the PI3K/AKT pathway under different conditions by virtue of their advantageous interaction with PI3K. CONCLUSIONS These ingredients have outstanding therapeutic potential and may provide a scientific basis for the future application and research of NXT.

Abstract
Timely myocardial reperfusion salvages ischemic myocardium from infarction, whereas reperfusion itself induces cardiomyocyte death, which is called myocardial ischemia/reperfusion (MI/R) injury. Herein, β-carboline derivative 17c was designed and synthesized with obvious myocardial protective activity for the first time. Pretreatment of 17c effectively protected the cardiomyocyte H9c2 cells from H2O2-induced lactate dehydrogenase leakage and restored the endogenous antioxidants, superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Besides, 17c effectively protected the mitochondria through decreasing the reactive oxygen species overproduction and enhancing the mitochondrial membrane potential. As a result, 17c significantly reduced the necrosis of cardiomyocytes in H2O2-induced oxidative stress, which was more potent than polydatin. In MI/R injury rats, 17c pretreatment obviously increased the levels of SOD and GSH-Px and inhibited the apoptosis of cardiomyocytes. Through this way, the size of myocardial infarction was significantly reduced after MI/R injury in vivo, better than that of polydatin, suggesting that 17c is a promising cardioprotectant for the prevention of MI/R injury.

Abstract
Cerebral ischemia has led to a high rate of both disability and mortality with massive healthcare costs. Although transcriptional regulation is typically mediated by different combinations of TFs, a combined regulatory unit to synergistically activate transcription has remained unclear in cerebral ischemia, especially in different drug treatments. In this study, TFs alterations after 6 h cerebral ischemic injury and repair were performed by a concatenated tandem array of consensus transcription factor response elements (catTFREs), and vital TFs were obtained by TFs-target imbalanced network. Drug intervention used Danhong injection (DHI) and BNC (BuChang NaoXinTong Capsules), which has been widely prescribed in Chinese herb medicine for the treatment of cerebrovascular and cardiovascular diseases. There were 198 TFs identified after 6 h MCAO operation, and six TFs (Sox2, Smad3, FoxO1, Creb1, Egr,1 and Smad4) were considered as critical TFs in response to cerebral ischemia. Moreover, Smad3 was identified as a hub TF among six vital TFs, and the transcription activity of Smad3 was further verified. These 6 TFs were all reversed by DHI or BNC, indicating different medications may regulate different transcription factors through TF synergy. Moreover, validation results indicated that Smad3 was a putative target TF for DHI and BNC-mediated protection against cerebral ischemia. The observations of the present study provide a fresh understanding of biomolecules and possible new avenues for therapeutic interventions, in addition to the new intervention pattern for different treatments for ischemia stroke.

Abstract
Ischemic heart disease (IHD), a severe condition of myocardium facing impediment in the supply of basic needs for cellular metabolism is caused by atherosclerosis. Though statin drugs could control the use of surgery on IHD patients, the complete rehabilitation or prophylaxis can be achieved through herbal-based medicines viz. either in the form of crude extract or pure phytocompounds. In the present study, pretreatment with leaf extract of Nelumbo nucifera Gaertn. was investigated for cardioprotective activity-in vitro by mitigating H2O2-induced oxidative stress. Analysis such as estimation of antioxidants, lipid peroxidation, and DNA fragmentation assay revealed significant protective effect of plant extract on cardiomyocytes. Reactive oxygen species detection was done by using 2',7'-dichlorofluorescein diacetate, apoptosis detection with Acridine Orange/Ethidium Bromide and nuclear damage detection by diamidino-2-phenylindole which confirmed the protective effect of N. nucifera extract. In addition, gene expression studies of apoptotic regulatory genes (Bcl2 and Cas-9) resulted in significant protection of nucifera extract pretreated and maintained cells. To conclude, in vitro cardioprotective activity of N. nucifera against H2O2 induced oxidative stress was achieved at the concentration of 50 µg/ml. Therefore, major phytocompounds present in extract could be beneficial in managing cardiac complications in the future.

Abstract
Background Amino acids (AAs) in cerebrospinal fluid (CSF) play a pivotal role in cerebral ischemia (CI). BuChang NaoXinTong Capsules (BNC) are widely prescribed in Chinese medicine for the treatment of cerebrovascular and cardiovascular diseases. Methods In order to investigate the therapeutic effects and pharmacological mechanisms of BNC on reversing CI from a system level, an amino acid-protein interaction imbalanced network of CI containing metabolites of AAs, key regulatory enzymes, and proteins was constructed for the first time. Furthermore, a novel method for detecting the ten AAs in CSF was developed by UPLC-QQQ-MS in an effort to validate the imbalanced networks and the therapeutic effects of BNC via analysis of metabolites. Results Based on a middle cerebral artery occlusion (MCAO) rat model, the dynamic levels of amino acids in CSF 3, 6, 12, and 24 h after MCAO were analyzed. Up to 24 h, the accumulated nine AA biomarkers were found to significantly change in the MCAO group compared to the sham group and exhibited an obvious tendency for returning to baseline values after BNC treatment. In addition, based on the imbalanced network of CI, four key enzymes that regulate the generation of BNC-mediated AA biomarkers were selected and validated using an enzyme-linked immunosorbent assay and western blotting. Finally, aromatic-L-amino-acid decarboxylase (AADC) was found to be one of the putative targets for BNC-mediated protection against CI. Conclusion This study provides new strategies to explore the mechanism of cerebral ischemia and help discover the potential mechanism of BNC.

Abstract
Orexin-A elicits multiple potent effects on a variety of tumor cells via
different signaling pathways. However, it is unknown whether it has a
neuroprotective effect on SH-SY5Y human neuroblastoma cells. This study
investigated the neuroprotective effect of Orexin-A against hydrogen peroxide
(H2O2)-induced oxidative damage in SH-SY5Y cells and
the underlying mechanism. H2O2 treatment decreased the
viability of SH-SY5Y cells, induced apoptosis, and decreased superoxide
dismutase activity. Orexin-A attenuated these effects, indicating that it
protects SH-SY5Y cells against H2O2-induced oxidative
damage. Pre-treatment with Orexin-A also attenuated
H2O2-induced increases in phosphorylation of
MEK1/2 and ERK1/2. Moreover, these effects of Orexin-A
were reduced in the presence of the PI3K inhibitor LY294002. Finally,
pre-treatment with LY294002 abrogated attenuation of the
H2O2-induced decrease in cell viability and increase
in caspase-3/7 activity by Orexin-A. These results show that the
PI3K/MEK1/2/ERK1/2 signaling pathway is involved in
the neuroprotective effects of Orexin-A against
H2O2-induced oxidative damage in SH-SY5Y cells. Our
findings provide insight into the neuroprotective effects of Orexin-A and the
underlying mechanism, which will be useful for the treatment of nervous system
diseases.

Abstract
NaoXinTong Capsule (NXT), a Chinese medicine, is currently used to treat patients with cardiovascular and cerebrovascular diseases. Clinical observations indicate its anti-diabetic functions with unclear mechanisms. Herein, we report the effect of NXT on diabetic nephropathy (DN). Type 2 diabetic db/db mice were treated with NXT for 14 weeks. In the course of treatment, NXT reduced diabetes-increased glucose levels and improved renal functions. At the end of treatment, we found that NXT ameliorated serum lipid profiles and other biochemical parameters. In the kidney, NXT inhibited mesangial matrix expansion, expression of vascular endothelial growth factor A, fibronectin, advanced glycation end product and its receptor. Meanwhile, it reduced the diabetes-induced podocyte injury by increasing WT1 and nephrin expression. In addition, NXT inhibited accumulation of extracellular matrix proteins by increasing MMP2/9 expression through inactivation of TGFβ/Smad pathway and CTGF expression. Mechanically, NXT activated insulin signaling pathway by increasing expression of INSR, IRS and FGF21, phosphorylation of Akt and AMPKα in the liver, INSR phosphorylation in the kidney, and FGF21 and GLUT4 expression in adipose tissue and skeletal muscle. Taken together, our study demonstrates that NXT inhibits DN by ameliorating glucose/lipid metabolism, maintaining tissue structure integrity, and correcting diabetes-induced renal dysfunctions.

Abstract
For the first time, we have determined the effect of solvent, liquid-solid ratio and extraction time on polysaccharides yield was evaluated using a full factorial design (23). In this present investigation, a total of 7 molecules were determined in this species. In our analysis saccharose was the dominant monosaccharides. Arabinose, pyranose, fructose, glucose, inositol, saccharose and trehalose found in E. bivonae. The results of the in vitro antioxidant assay showed that the EBPS have higher antioxidant capacity. Accordingly, the HEK293 cells pre-treated with EBPS compounds (100 μg·mL-1) enhanced cell viability against H2O2 exposure. Our results revealed that H2O2-exposure induced a significant increase in intracellular ROS and lipid peroxidation in HEK293 cells. Additionally, the H2O2-induced alteration in HEK293 cells morphology, was ameliorated by EBPS treatment. In addition, EPBS pre-treated cells significantly enhanced the activities of HEK293 cells antioxidant status (SOD, CAT, GPx and GSH) that were decreased after hydrogen peroxide exposure.

Abstract
Buchang NaoXinTong (NXT) is a Chinese medicine that has been used for many years for treatment of patients with coronary heart disease (CHD) in China. Statins substantially reduce hypercholesterolemia and CHD mortality and morbidity. However, there is still a lot of CHD patients who do not respond well to statin therapy. Herein, we report the effects of NXT on atorvastatin-inhibited atherosclerosis and atorvastatin-induced hepatic side effects. After 10 weeks of high-fat diet (HFD) feeding, apoE-deficient mice were randomly divided into 4 groups and received the following treatment for another 8 weeks: group 1, HFD; group 2, HFD containing NXT; group 3, HFD containing atorvastatin; and group 4, HFD containing both NXT and atorvastatin. After treatment, serum lipid profiles, atherosclerotic lesions, and hepatic lipid content and inflammation were determined. NXT moderately increased high-density lipoprotein cholesterol levels, although had little effect on atorvastatin-induced reduction of low-density lipoprotein cholesterol levels. Both NXT and atorvastatin reduced en face lesions and sinus lesions of aortic root. In addition, NXT enhanced atorvastatin-induced lesion plaque stability by increasing smooth muscle cell/collagen content and reducing macrophage accumulation and calcification in lesion areas. The co-treatment of NXT and atorvastatin further reduced hepatic triglyceride levels by downregulating acyl-CoA:diacylglycerol acyltransferase 1 while activating hormone-sensitive lipase, adipose triglyceride lipase, and comparative gene identification-58 expression. The AMPKα pathway was also further activated by the co-treatment. More importantly, the liver injuries caused by atorvastatin, such as hepatic inflammation and elevated serum aminotransferase activities, were substantially attenuated by NXT. Therefore, our study demonstrates that NXT enhances atorvastatin-induced plaque stability and ameliorates atorvastatin-induced hepatic side effects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Naoxintong capsules (NXT), a traditional Chinese Medical preparation, are widely used for treatment of cardiovascular diseases, while the mechanism is still unclear. MATERIALS AND METHODS Myocardial infarction (MI) was induced by ligation of the left coronary artery in mice. Echocardiographic measurements were performed to do physiological assessments of left ventricle (LV) function. Histological and immunohistochemical staining was used to determine infarct size, capillary density, tissue endothelial nitric oxide synthase (eNOS) expression. Bone Marrow Transplantation (BMT) model and flow cytometric (FCM) analyses were applied to assay endothelial progenitor cells (EPCs) mobilization. Quantitative Real-Time Reverse Transcription Polymerase Chain Reaction (qRT-PCR), Western blotting and enzyme-linked immunosorbent assay (ELISA) were performed to detect the expressions of vascular endothelial growth factor (VEGF), kinase domain region (KDR), phosphorylated-Akt (p-Akt), phosphorylated-eNOS (p-eNOS). RESULTS NXT administration reduced myocardium fibrosis and increased myocardium capillary density in response to MI. NXT increased circulating Sca1+/ Fetal liver kinase 1 (Flk1)+ mononuclear cells (MNCs) and soluble Kit ligand (sKitL) of bone marrow (BM) in response to MI. In mice transplanted with green fluorescent protein (GFP) BM cells, NXT increased the numbers of GFP-positive cells at the border zone of the ischemic region in MI-induced mice. NXT increased the numbers of eNOS-expressing BM-derived cells in tissues, which was involved in increased the expressions of VEGF, KDR, p-eNOS, p-Akt in the myocardium. CONCLUSION NXT-mediated recovery in MI-induced mice was involved in mobilization and incorporation of bone marrow-derived EPCs/circulating angiogenic cells (CACs) leading to enhancement of neovascularization via VEGF/eNOS signaling.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:9057238. [PMID: 28757891 PMCID: PMC5516711 DOI: 10.1155/2017/9057238] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/30/2017] [Accepted: 05/30/2017] [Indexed: 11/18/2022]
Abstract
Naoxintong capsule (NXTC) was a famous patent medicine of Traditional Chinese Medicine (TCM) to treat cerebrovascular diseases in China. An LC-MS/MS method was developed for simultaneous determination of 11 major ingredients (paeoniflorin, ecdysterone, amygdalin, mulberroside A, caffeic acid, ferulic acid, salvianolic acid B, astragaloside IV, formononetin, cryptotanshinone, and tanshinone IIA) in NXTC in rat plasma. All analytes were separated on an Eclipse plus C18 column using a gradient mobile phase system of acetonitrile-0.1% formic acid aqueous solution. The lower limits of quantification of 11 ingredients were between 0.075 and 10 ng mL−1. The precision was less than 15% and the accuracies were between 85% and 115%. The results showed that caffeic acid, ferulic acid, formononetin, cryptotanshinone, and tanshinone IIA could be detected after oral administration of NXTC. The validated method was successfully applied to pharmacokinetic study of the caffeic acid, ferulic acid, formononetin, cryptotanshinone, and tanshinone IIA in rats after oral administration of NXTC at single and triple dose.

Abstract
Background: Trimetazidine is a fatty oxidation inhibitor, leading to shifting of energy substrate from fatty acid oxidation toward glucose oxidation that leads to the reduction of oxygen requirement. The aims of the present study were to elucidate the effects of trimetazidine on psychomotor performance and vigilance on normal healthy volunteers. Materials and Methods: A total of 234 subjects (age 22–25 years) were recruited in this study. The volunteers were randomizing into two groups with 117 volunteers in each group. Group I received an inert starch capsule served as a control, and Group II received trimetazidine tablet 15 mg/day. The duration of therapy was 5 days. Test procedure was done at 9.00 a.m. on the psychomotor tester. Before the drug administration, prescore values were recorded and then after 5 days of therapy, the postscore values were recorded. Results: The placebo did not demonstrate a significant effect on all psychomotor performances and flicker-fusion elements (P > 0.05). Trimetazidine therapy produced a highly significant effect on all components of psychomotor performances and flicker-fusion parameters (P < 0.001) compared with pretreatment era. Conclusion: We conclude that trimetazidine improves psychomotor performance and vigilance in normal healthy volunteers through advancing total reaction time and critical flicker-fusion frequency.

Abstract
As a traditional Chinese medicine, Naoxintong capsule (NXT) has been approved by China Food and Drug Administration (CFDA), which is used for cardiocerebrovascular disease treatment. Here we found that NXT extract significantly promoted H9c2 cardiomyocyte cell autophagy involved in increased autophagy-associated gene expression leading to inhibition of mTOR signaling. Moreover, NXT extract increased PPARγ protein expression and transcription activity of H9c2 cell. Consistent with this, in PPARγ gene silenced H9c2 cells, NXT had no effect on autophagy and mTOR signaling. Furthermore, NXT/PPARγ-mediated H9c2 autophagy led to inhibition of cardiomyocyte cell hypertrophy. These findings suggest that the extract of NXT inhibited H9c2 cardiomyocyte cell hypertrophy via PPARγ-mediated cell autophagy.

Abstract
Diabetes mellitus is one of the most frequent endocrine disorders, affecting populations worldwide. Diabetic retinopathy (DR) is the most frequent microvascular complication of diabetes in patients aged 20 and over. Major complications of DR include intraocular neovascularization, inter-retinal edema, hemorrhage, exudates and microaneurysms. Therefore, timely medical attention and prevention are required. At present, laser-assisted therapy and other operational procedures are the most common treatment for DR. However, these treatments can cause retinal damage and scarring. Also, use of the majority of traditional medicines is not supported by clinical evidence. However, due to accumulating scientific evidence, traditional natural medications may assist in delaying or preventing the progression of DR. This review focuses on evidence for the role of traditional natural medicines and their mechanisms of action and pharmacological test results in relation to the progression of DR.

Abstract
Buchang NaoXinTong (NXT), a Chinese medicine, has been widely used to treat patients with coronary heart disease in China. However, the underlying mechanisms need more elucidations. In this study, we investigated if NXT can inhibit the progression of the established lesions while stabilizing plaques. Apolipoprotein E deficient (apoE(-/-)) mice in 3 groups received following treatment: group 1 was fed a high-fat diet (HFD) for 18 weeks; group 2 was prefed HFD for 12 weeks followed by HFD containing NXT for additional 6 weeks; group 3 was prefed HFD for 8 weeks followed by HFD containing NXT for additional 10 weeks. After treatment, serum and aorta samples were collected and determined lipid profiles, lesions, collagen content, mineralization, and macrophage accumulation in aortic root, respectively. NXT had slight effect on serum lipid profiles but significantly reduced progression of the advanced lesions. In aortic wall, NXT increased smooth muscle cell/collagen content in lesion cap while reducing buried fibrous caps, mineralization, and macrophage accumulation within lesions, which suggests that NXT can stabilize plaques. In addition, NXT increased expression of smooth muscle 22α mRNA while inhibiting expression of matrix metalloproteinase-2 and tumor necrosis factor α mRNA in aortas. Our study demonstrates that NXT can reduce advanced atherosclerosis and enhance the plaque stability in apoE(-/-) mice.

Abstract
Naoxintong (NXT) is a Chinese Materia Medica standardized product extracted from 16 various kinds of Chinese traditional herbal medicines including Salvia miltiorrhiza, Angelica sinensis, Astragali Radix. Naoxintong is clinically effective in treating ischaemia heart disease. Nucleotide‐binding oligomerization domain‐Like Receptor with a Pyrin domain 3 (NLRP3) inflammasome has been critically involved in myocardial ischaemia/reperfusion (I/R) injury. Here, we have been suggested that NXT might attenuate myocardial I/R injury via suppression of NLRP3 inflammasome activation. Male C57BL6 mice were subjected to myocardial I/R injury via 45 min. coronary ligation and release for the indicated times. Naoxintong (0.7 g/kg/day) and PBS were orally administrated for 2 weeks before surgery. Cardiac function assessed by echocardiography was significantly improved in the NXT group compared to PBS group at day 2 after myocardial I/R. NLRP3 inflammasome activation is crucially involved in the initial inflammatory response after myocardial I/R injury, leading to cleaved caspase‐1, mature interleukin (IL)‐1β production, accompanying by macrophage and neutrophil infiltration. The cardioprotective effect of NXT was associated with a diminished NLRP3 inflammasome activation, decreased pro‐inflammatory macrophage (M1 macrophages) and neutrophil infiltration after myocardial I/R injury. In addition, serum levels of IL‐1β, indicators of NLRP3 inflammasome activation, were also significantly suppressed in the NXT treated group after I/R injury. Naoxintong exerts cardioprotive effects at least partly by suppression of NLRP3 inflammasome activation in this I/R injury model.

Abstract
Naoxintong (NXT) is an empirical formula based on the principle of traditional Chinese medicine, which has been approved by China Food and Drug Administration (CFDA) and is widely used for treatment of patients with cerebrovascular and cardiovascular diseases in China. The aim of this study is to investigate the protective mechanism of NXT on H9c2 cells (cardiogenic cell line) in response to H2O2. MTT, Western blot, and flow cytometry (FCM) methods were used to identify the protective effect of NXT extract on H2O2-induced H9c2 cells. Here we found that NXT extract significantly increased H9c2 cell viability and reduced H2O2-induced cell apoptosis and autophagy. More importantly, NXT inhibited H2O2-induced H9c2 cell apoptosis and autophagy by increasing PPARα protein levels. In contrast, silenced PPARα terminated NXT protective effect on H2O2-induced H9c2 cells. These findings suggest that NXT/PPARα signaling suppressed H2O2-induced H9c2 cell apoptosis and autophagy.

Abstract
BACKGROUND Cytochrome P450 2C19 (CYP2C19) is an important drug-metabolizing enzyme (DME), which is responsible for the biotransformation of several kinds of drugs such as proton pump inhibitors, platelet aggregation inhibitors and antidepressants. Previous studies showed that Buchang NaoXinTong capsules (NXT) increased the CYP2C19 metabolic activity in vitro and enhanced the antiplatelet effect of clopidogrel in vivo. However, the underlying molecular mechanism remained unclear. In the present study, we examined whether Pregnane X receptor (PXR) plays a role in NXT-mediated regulation of CYP2C19 expression. METHODS We applied luciferase assays, real-time quantitative PCR (qPCR), Western blotting and cell-based analysis of metabolic activity experiments to investigate the NXT regulatory effects on the CYP2C19 promoter activity, the mRNA/ protein expression and the metabolic activity. RESULTS Our results demonstrated that NXT significantly increased the CYP2C19 promoter activity when co-transfected with PXR in HepG2 cells. Mutations in PXR responsive element abolished the NXT inductive effects on the CYP2C19 promoter transcription. Additionally, NXT incubation (150 and 250μg/mL) also markedly up-regulated endogenous CYP2C19 mRNA and protein levels in PXR-transfected HepG2 cells. Correspondingly, NXT leaded to a significant enhancement of the CYP2C19 catalytic activity in PXR-transfected HepG2 cells. CONCLUSION In summary, this is the first study to suggest that NXT could induce CYP2C19 expression via PXR activation.

Abstract
Introduction. Luteolin, a falconoid compound in many Chinese herbs and formula, plays important roles in cardiovascular diseases. The underlying mechanism of luteolin remains to be further elaborated. Methods. A model of hydrogen peroxide- (H2O2-) induced H9C2 cells apoptosis was established. Cell viabilities were examined with an MTT assay. 2′,7′-Dichlorofluorescin diacetate (DCFH-DA) and flow cytometry were used to detect ROS level and apoptosis rate, respectively. The expressions of signaling proteins related to apoptosis were analyzed by western blot and mRNA levels were detected by real-time polymerase chain reaction (PCR). Quercetin was applied as positive drug. Results. Incubation with various concentrations of H2O2 (0, 50, 100, and 200 μM) for 1 h caused dose-dependent loss of cell viability and 100 μM H2O2 reduced the cell viability to approximately 50%. Treatments with luteolin and quercetin protected cells from H2O2-induced cytotoxicity and reduced cellular ROS level and apoptosis rate. Moreover, luteolin could downregulate the expressions of Bax, caspase-8, cleaved-caspase-3, and p53 in apoptotic signaling pathway. Further study showed that the expressions of Akt, Bcl-2, and Mdm2 were upregulated by luteolin. Conclusion. Luteolin protects H9C2 cells from H2O2-induced apoptosis. The protective and antiapoptotic effects of luteolin could be mediated by regulating the Akt-P53/Mdm2 apoptotic pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Naoxintong (NXT), a renowned traditional Chinese medicine in China, has been used for the treatment of acute and chronic cardio-cerebrovascular diseases in clinic for more than 20 years. AIM OF THE STUDY To evaluate the potential neuroprotective effect of NXT against ischemia reperfusion (I/R) injury in mice and investigate the underlying mechanisms. MATERIALS AND METHODS Focal cerebral I/R injury in adult male CD-1 mice was induced by transient middle cerebral artery occlusion (tMCAO) for 1h followed by reperfusion for 23h. Mice were randomly divided into five groups: Sham group; tMCAO group; Vehicle group; NXT-treated groups at doses of 0.36g/kg and 0.54g/kg. The effects of NXT on murine neurological function were estimated by neurological defect scores, infarct volume and brain water content at 24h after tMCAO. Immunohistochemistry and Western blot were used to detect the expression of LOX-1, pERK1/2 and NF-κB at 24h after tMCAO. qRT-PCR was used to detect the expression of LOX-1 and NF-κB at 24h after tMCAO. RESULTS Compared with Vehicle group, 0.54g/kg group of NXT significantly ameliorated neurological outcome, infarction volume and brain water content, decreased the expression of LOX-1, pERK1/2 and NF-κB (P<0.05). CONCLUSION NXT protected the mice brain against I/R injury, and this protection maybe associated with the down-regulation of LOX-1, pERK1/2 and NF-κB expression.

Abstract
Naoxintong capsule (NXT) is a commercial medicinal product approved by the China Food and Drug Administration which is used in the treatment of stroke and coronary heart disease. However, the research on the composition and mechanism of NXT is still lacking. Our research aimed to identify the absorbable components, potential targets, and associated pathways of NXT with network pharmacology method. We explored the chemical compositions of NXT based on UPLC/Q-TOF-MS. Then, we used the five principles of drug absorption to identify absorbable ingredients. The databases of PharmMapper, Universal Protein, and the Molecule Annotation System were used to predict the main targets and related pathways. By the five principles of drug absorption as a judgment rule, we identified 63 compositions that could be absorbed in the blood in all 81 chemical compositions. Based on the constructed networks by the significant regulated 123 targets and 77 pathways, the main components that mediated the efficacy of NXT were organic acids, saponins, and tanshinones. Radix Astragali was the critical herbal medicine in NXT, which contained more active components than other herbs and regulated more targets and pathways. Our results showed that NXT had a therapeutic effect on heart diseases through the pattern “multiple components-multiple targets-multiple pathways.”

Abstract
Short-chain acyl-CoA dehydrogenase (SCAD), a key enzyme of fatty acid β-oxidation, plays an important role in cardiac hypertrophy. However, its effect on the cardiomyocyte apoptosis remains unknown. We aimed to determine the role of SCAD in tert-butyl hydroperoxide (tBHP)-induced cardiomyocyte apoptosis. The mRNA and protein expression of SCAD were significantly down-regulated in the cardiomyocyte apoptosis model. Inhibition of SCAD with siRNA-1186 significantly decreased SCAD expression, enzyme activity and ATP content, but obviously increased the content of free fatty acids. Meanwhile, SCAD siRNA treatment triggered the same apoptosis as cardiomyocytes treated with tBHP, such as the increase in cell apoptotic rate, the activation of caspase3 and the decrease in the Bcl-2/Bax ratio, which showed that SCAD may play an important role in primary cardiomyocyte apoptosis. The changes of phosphonate AMP-activated protein kinase α (p-AMPKα) and Peroxisome proliferator-activated receptor α (PPARα) in cardiomyocyte apoptosis were consistent with that of SCAD. Furthermore, PPARα activator fenofibrate and AMPKα activator AICAR treatment significantly increased the expression of SCAD and inhibited cardiomyocyte apoptosis. In conclusion, for the first time our findings directly demonstrated that SCAD may be as a new target to prevent cardiomyocyte apoptosis through the AMPK/PPARα/SCAD signal pathways.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Buchang Naoxintong Capsules (BNC) are widely prescribed in Chinese medicine for the treatment of cerebrovascular and cardiovascular diseases. However, the therapeutic effects and mechanisms are not yet well understood. MATERIALS AND METHODS In this study, a UPLC/TOF-MS-based metabolomic study was conducted to explore potential biomarkers that will increase our understanding of cerebral ischemia and to assess the integral efficacy of BNC in a middle cerebral artery occlusion (MCAO) rat model. Plasma metabolic profiles were analyzed and metabolic biomarkers were identified through multivariate data analysis. RESULTS Clear separations were observed between the sham, MCAO and BNC-treated groups. We identified 28 biomarkers in the MCAO rats using variable importance for the projections (VIP) values (VIP>1) and a t-test (P<0.05). The identified biomarkers were mainly related to disturbances in monoamine neurotransmitter metabolism, amino acid metabolism, energy metabolism and lipid metabolism. Moreover, a correlation network diagram of the plasma biomarkers perturbed by MCAO was constructed. Some biomarkers, such as glutamine, PE (17:0), LysoPE (20:1), LysoPE (24:0), and the ratios of LysoPE (24:1) to LysoPE (24:0), LysoPE (24:2) to LysoPE (24:0), showed obvious changes and a tendency for returning to baseline values in BNC-treated MCAO rats. In addition, MCAO rats receiving BNC treatment had improved neurological deficits and reduced cerebral infarct size demonstrating the therapeutic potential of BNC for treating cerebral ischemia. CONCLUSION This study provides a useful approach for exploring the mechanism of MCAO-induced cerebral ischemia and evaluating the efficacy of BNC.

Naoxintong Protects Primary Neurons from Oxygen-Glucose Deprivation/Reoxygenation Induced Injury through PI3K-Akt Signaling Pathway. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:5815946. [PMID: 26949405 PMCID: PMC4754490 DOI: 10.1155/2016/5815946] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/25/2015] [Accepted: 12/24/2015] [Indexed: 12/11/2022]
Abstract
Naoxintong capsule (NXT), developed from Buyang Huanwu Decoction, has shown the neuroprotective effects in cerebrovascular diseases, but the neuroprotection mechanisms of NXT on ischemia/reperfusion injured neurons have not yet been well known. In this study, we established the oxygen-glucose deprivation/reoxygenation (OGD/R) induced neurons injury model and treat the neurons with cerebrospinal fluid containing NXT (BNC) to investigate the effects of NXT on OGD/R induced neurons injury and potential mechanisms. BNC improved neuron viability and decreased apoptotic rate induced by OGD/R. BNC attenuated OGD/R induced cytosolic and mitochondrial Ca(2+) overload, ROS generation, intracellular NO levels and nNOS mRNA increase, and cytochrome-c release when compared with OGD/R group. BNC significantly inhibited both mPTP opening and ΔΨm depolarization. BNC increased Bcl-2 expression and decreased Bax expression, upregulated the Bcl-2/Bax ratio, downregulated caspase-3 mRNA and caspase-9 mRNA expression, and decreased cleaved caspase-3 expression and caspase-3 activity. BNC increased phosphorylation of Akt following OGD/R, while LY294002 attenuated BNC induced increase of phosphorylated Akt expression. Our study demonstrated that NXT protected primary neurons from OGD/R induced injury by inhibiting calcium overload and ROS generation, protecting mitochondria, and inhibiting mitochondrial apoptotic pathway which was mediated partially by PI3K-Akt signaling pathway activation.

Abstract
For a multicomponent therapy, molecular network is essential to uncover its specific mode of action from a holistic perspective. The molecular system of a Traditional Chinese Medicine (TCM) formula can be represented by a 2-class heterogeneous network (2-HN), which typically includes chemical similarities, chemical-target interactions and gene interactions. An important premise of uncovering the molecular mechanism is to identify mixed modules from complex chemical-gene heterogeneous network of a TCM formula. We thus proposed a novel method (MixMod) based on mixed modularity to detect accurate mixed modules from 2-HNs. At first, we compared MixMod with Clauset-Newman-Moore algorithm (CNM), Markov Cluster algorithm (MCL), Infomap and Louvain on benchmark 2-HNs with known module structure. Results showed that MixMod was superior to other methods when 2-HNs had promiscuous module structure. Then these methods were tested on a real drug-target network, in which 88 disease clusters were regarded as real modules. MixMod could identify the most accurate mixed modules from the drug-target 2-HN (normalized mutual information 0.62 and classification accuracy 0.4524). In the end, MixMod was applied to the 2-HN of Buchang naoxintong capsule (BNC) and detected 49 mixed modules. By using enrichment analysis, we investigated five mixed modules that contained primary constituents of BNC intestinal absorption liquid. As a matter of fact, the findings of in vitro experiments using BNC intestinal absorption liquid were found to highly accord with previous analysis. Therefore, MixMod is an effective method to detect accurate mixed modules from chemical-gene heterogeneous networks and further uncover the molecular mechanism of multicomponent therapies, especially TCM formulae.

NaoXinTong Inhibits the Development of Diabetic Retinopathy in db/db Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:242517. [PMID: 25821481 PMCID: PMC4363582 DOI: 10.1155/2015/242517] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/30/2014] [Revised: 12/08/2014] [Accepted: 12/16/2014] [Indexed: 01/14/2023]
Abstract
Buchang NaoXinTong capsule (NXT) is a Chinese Materia Medica standardized product extracted from 16 Chinese traditional medical herbs and widely used for treatment of patients with cerebrovascular and cardiovascular diseases in China. Formation of microaneurysms plays an important role in the development of diabetic retinopathy. In this study, we investigated if NXT can protect diabetic mice against the development of diabetic retinopathy. The db/db mice (~6 weeks old), a diabetic animal model, were divided into two groups and fed normal chow or plus NXT for 14 weeks. During the treatment, fasting blood glucose levels were monthly determined. After treatment, retinas were collected to determine retinal thickness, accumulation of carbohydrate macromolecules, and caspase-3 (CAS-3) expression. Our results demonstrate that administration of NXT decreased fasting blood glucose levels. Associated with the decreased glucose levels, NXT blocked the diabetes-induced shrink of multiple layers, such as photoreceptor layer and outer nuclear/plexiform layers, in the retina. NXT also inhibited the diabetes-induced expression of CAS-3 protein and mRNA, MMP-2/9 and TNFα mRNA, accumulation of carbohydrate macromolecules, and formation of acellular capillaries in the retina. Taken together, our study shows that NXT can inhibit the development of diabetic retinopathy and suggests a new potential application of NXT in clinic.

Abstract
Xueshuan Xinmaining Tablet (XXT), the Chinese formula, has long been administered in clinical practice for the treatment of cerebral thrombosis and coronary heart disease. In this study, we aimed to study the effect and the molecular mechanism of activating blood circulation and removing blood stasis. Rat models of cold coagulation blood stasis were induced with ice-water bath and epinephrine to assess the amelioration of blood stasis by XXT. Microarray technique was used to identify gene expression from the model and XXT-treated rats. In addition, Quantitative Real-Time PCR (qPCR) was performed to verify the microarray results. The results showed that XXT had a good therapeutic effect on blood stasis by reducing the whole blood viscosity (WBV), plasma viscosity (PV), increasing PT, APTT and TT, and by inhibiting platelet aggregation. Genes were differentially expressed in rats among the model group and the XXT-pretreated groups. XXT ameliorated blood stasis by regulating the expressions of F13a1, Car1, and Tbxa2r.

Abstract
The BuChang NaoXinTong (BNC) capsule is a well-known, traditional, prescribed Chinese medication for the treatment of cardiovascular and cerebrovascular diseases. Nevertheless, the chemical profile of BNC has not been established. In the present study, ultra-high-pressure liquid chromatography coupled with linear ion trap-Orbitrap tandem mass spectrometry (UHPLC-LTQ-Orbitrap) has been developed for rapid and high-throughput screening of the preliminary chemical profile of BNC in both positive and negative ion modes. Twenty-five compounds were identified as the standard available compounds by comparing the retention time and high-resolution accurate mass. For the standard unavailable compounds, the structures were presumed based on high-accuracy protonated precursors and multi-stage mass spectrometry (MS(n)) using the proposed strategy. In particular, flavones, isoflavones, and tanshinones had the same skeleton. Therefore, the standards were utilized to characterize the fragment pathways and diagnostic fragment ions that could be applied for structural elucidation of their derivatives. Meanwhile, all the constituent groups of the compounds were detected in the individual herbs comprising BNC. Finally, a total of 178 components were identified or tentatively characterized in BNC, including 21 flavones and 6 flavone glycosides, 18 phenanthraquinones, and 22 terpenoids. The identification and structure elucidation of these chemicals provide essential data for further phytochemical studies, quality control, and pharmacological studies of BNC.
