The Extract of Scutellaria baicalensis Attenuates the Pattern Recognition Receptor Pathway Activation Induced by Influenza A Virus in Macrophages. Viruses 2023; 15:1524. [PMID: 37515209 PMCID: PMC10384909 DOI: 10.3390/v15071524] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 06/23/2023] [Accepted: 06/28/2023] [Indexed: 07/30/2023] Open
Abstract
The dual strategy of inhibiting the viral life cycle and reducing the host inflammatory response should be considered in the development of therapeutic drugs for influenza A virus (IAV). In this study, an extract of Scutellaria baicalinase (SBE) containing seven flavonoids was identified to exert both antiviral and anti-inflammatory effects in macrophages infected with IAV. We performed transcriptome analysis using high-throughput RNA sequencing and identified 315 genes whose transcription levels were increased after IAV infection but were able to be decreased after SBE intervention. Combined with Gene Ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis, these genes were mainly involved in TLR3/7/8, RIG-I/MDA5, NLRP3 and cGAS pattern recognition receptor (PRR)-mediated signaling pathways. SBE inhibited the transcription of essential genes in the above pathways and nuclear translocation of NF-κB p65 as confirmed by RT-qPCR and immunofluorescence, respectively, indicating that SBE reversed PR8-induced over-activation of the PRR signaling pathway and inflammation in macrophages. This study provides an experimental basis for applying Scutellaria baicalensis and its main effects in the clinical treatment of viral pneumonia. It also provides novel targets for screening and developing novel drugs to prevent and treat IAV infectious diseases.

Abstract
Aquaporins (AQPs) and vasopressin type 2 receptor (V2R) play a crucial role in urine excretion and are widely used to explore novel diuretics. In this study, three phenylpropanoids including stachysoside A (L1), acteoside (L2), and glucopyranosyl (1 → 6) martynoside (L3) were isolated from Lagopsis supina (Steph. ex Willd.) lk. -Gal. ex Knorr. Their diuretic activity, mechanism, molecular docking, and structure-activity relationships were explored. The results suggest that L1, L2, and L3 exhibit acute (6 h) and prolonged (6 d) activities including increased urinary excretion volume, diuretic action, and diuretic activity, without affecting the urinary pH and minor altering the electrolyte balance in saline-loaded rats. Further, L1, L2, and L3 significantly reduced the levels of angiotensin II (Ang II), anti-diuretic hormone (ADH), and aldosterone (ALD), AQPs 1-4 and 7, and V2R, and remarkably elevated the atriopeptin (ANP) level. Besides, L1, L2, and L3 obviously suppressed mRNA and protein levels of AQPs 1-4 and 7, and V2R. The hypothetical binding modes of L1, L2, and L3 with these proteins were determined by molecular docking, and a tight structure-activity relationship was also proposed. Collectively, L1, L2, and L3 represent three natively novel phenylethanoid glycoside diuretics, which inhibit AQP and V2R-mediated molecular mechanisms. They are superior to furosemide as long-term diuretics.

Abstract
The lower respiratory tract infection, induced by influenza virus, coronaviruses, and respiratory syncytial virus, remains a serious threat to human health that can cause a global pandemic. Thus, finding effective chemicals and therapeutic measures to advance the functional restoration of the respiratory tract after infection has been the emphasis of the studies on the subjects. Mosla scabra is a natural medicinal plant used for treating various lung and gastrointestinal diseases, including viral infection, cough, chronic obstructive pulmonary disease, acute gastroenteritis, and diarrhoea. In this study, the antiviral and anti-inflammatory effects of total lignans (MSTL) extracted from the plant were investigated in influenza A virus (IAV)-infected mice and RAW 264.7 macrophages. MSTL could not only protect the macrophages against IAV-induced pyroptosis but also could lighten the lung inflammation induced by IAV in vivo and in vitro. The network pharmacology analysis revealed that differentially expressed genes, mainly involving in EGFR tyrosine kinase inhibitor resistance, endocrine resistance, HIF-1 signaling pathway, C-type lectin receptor signaling pathway, and FOXO signaling pathway, contributed to the IAV-induced alveolar macrophage dysfunction. It indicated that MSTL enhanced the function of alveolar macrophages and improved IAV-induced lung injury in mice.

Abstract
Acute respiratory distress syndrome (ARDS) is a life-threatening lung injury characterized by an acute inflammatory response in the lung parenchyma. Hence, it is considered as the most appropriate clinical syndrome to study pathogenic mechanisms of lung inflammation. ARDS is associated with increased morbidity and mortality in the intensive care unit (ICU), while no effective pharmacological treatment exists. It is very important therefore to fully characterize the underlying pathobiology and the related mechanisms, in order to develop novel therapeutic approaches. In vivo and in vitro models are important pre-clinical tools in biological and medical research in the mechanistic and pathological understanding of the majority of diseases. In this review, we will present data from selected experimental models of lung injury/acute lung inflammation, which have been based on clinical disorders that can lead to the development of ARDS and related inflammatory lung processes in humans, including ventilation-induced lung injury (VILI), sepsis, ischemia/reperfusion, smoke, acid aspiration, radiation, transfusion-related acute lung injury (TRALI), influenza, Streptococcus (S.) pneumoniae and coronaviruses infection. Data from the corresponding clinical conditions will also be presented. The mechanisms related to lung inflammation that will be covered are oxidative stress, neutrophil extracellular traps, mitogen-activated protein kinase (MAPK) pathways, surfactant, and water and ion channels. Finally, we will present a brief overview of emerging techniques in the field of omics research that have been applied to ARDS research, encompassing genomics, transcriptomics, proteomics, and metabolomics, which may recognize factors to help stratify ICU patients at risk, predict their prognosis, and possibly, serve as more specific therapeutic targets.

Abstract
Influenza virus is one of the most common infectious pathogens that could cause high morbidity and mortality in humans. However, the occurrence of drug resistance and serious complications extremely complicated the clinic therapy. Mosla scabra is a natural medicinal plant used for treating various lung and gastrointestinal diseases, including viral infection, cough, chronic obstructive pulmonary disease, acute gastroenteritis, and diarrhoea. But the therapeutic effects of this herbal medicine had not been expounded clearly. In this study, a network pharmacology approach was employed to investigate the protective mechanism of total flavonoids from M. scabra (MSTF) against influenza A virus- (IAV-) induced acute lung damage and inflammation. The active compounds of MSTF were analyzed by LC-MS/MS and then evaluated according to their oral bioavailability and drug-likeness index. The potential targets of each active compound in MSTF were identified by using PharmMapper Server, whereas the potential genes involved in IAV infection were obtained from GeneGards. The results showed that luteoloside, apigenin, kaempherol, luteolin, mosloflavone I, and mosloflavone II were the main bioactive compounds found in MSTF. Primarily, 23 genes were identified as the targets of those five active compounds, which contributed to the inactivation of chemical carcinogenesis ROS, lipid and atherosclerosis, MAPK signaling pathway, pathways in cancer, PI3K-AKT signaling pathway, proteoglycans in cancer, and viral carcinogenesis. Finally, the animal experiments validated that MSTF improved IAV-induced acute lung inflammation via inhibiting MAPK, PI3K-AKT, and oxidant stress pathways. Therefore, our study demonstrated the potential inhibition of MSTF on viral pneumonia in mice and provided a strategy to characterize the molecular mechanism of traditional Chinese medicine by a combinative method using network pharmacology and experimental validation.

Luteolin attenuates lipopolysaccharide-induced acute lung injury/acute respiratory distress syndrome by activating alveolar epithelial sodium channels via cGMP/PI3K pathway. JOURNAL OF ETHNOPHARMACOLOGY 2022; 282:114654. [PMID: 34537283 DOI: 10.1016/j.jep.2021.114654] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 08/27/2021] [Accepted: 09/15/2021] [Indexed: 05/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Luteolin (Lut) was recently identified as the major active ingredient of Mosla scabra, which was a typical representative traditional Chinese medicine and had been used to treat pulmonary diseases for thousands of years. AIM OF THE STUDY This study was to explore the effects and relative mechanisms of Lut in LPS-induced acute lung injury/acute respiratory distress syndrome (ALI/ARDS). The main characteristic of ALI/ARDS is pulmonary edema, and epithelial sodium channel (ENaC) is a key factor in effective removal of excessive alveolar edematous fluid, which is essential for repairing gas exchange and minimizing damage to the peripheral tissues. However, whether the therapeutic effects of Lut on respiratory diseases are relative with ENaC is still unknown. MATERIALS AND METHODS Alveolar fluid clearance was calculated in BALB/c mice and ENaC function was measured in H441 cells. Moreover, ENaC membrane protein and mRNA were detected by Western blot and real-time PCR, respectively. We also studied the involvement of cGMP/PI3K pathway during the regulation of Lut on ENaC during LPS-induced ALI/ARDS by ELISA method and applying cGMP/PI3K inhibitors/siRNA. RESULTS The beneficial effects of Lut in ALI/ARDS were evidenced by the alleviation of pulmonary edema, and enhancement of both amiloride-sensitive alveolar fluid clearance and short-circuit currents. Lut could alleviate the LPS decreased expression levels of ENaC mRNA and membrane protein in H441 cells and mouse lung. In addition, cGMP concentration was increased after the administration of Lut in ALI/ARDS mice, while the inhibition of cGMP/PI3K pathway could abrogate the enhanced AFC and ENaC protein expression of Lut. CONCLUSION These results implied that Lut could attenuate pulmonary edema via enhancing the abundance of membrane ENaC at least partially through the cGMP/PI3K pathway, which could provide a promising therapeutic strategy for treating ALI/ARDS.

Abstract
Viral infections are among the most complex medical problems and have been a major threat to the economy and global health. Several epidemics and pandemics have occurred due to viruses, which has led to a significant increase in mortality and morbidity rates. Natural products have always been an inspiration and source for new drug development because of their various uses. Among all-natural sources, plant sources are the most dominant for the discovery of new therapeutic agents due to their chemical and structural diversity. Despite the traditional use and potential source for drug development, natural products have gained little attention from large pharmaceutical industries. Several plant extracts and isolated compounds have been extensively studied and explored for antiviral properties against different strains of viruses. In this review, we have compiled antiviral plant extracts and natural products isolated from plants reported since 2015.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Moslae Herba, a common traditional Chinese herb with special flavor, has potential for treating respiratory and gastrointestinal diseases. AIM OF THIS STUDY Lung endothelial barrier dysfunction (LEBD) accelerates the pathogenesis of influenza A virus (IAV)-induced secondary acute lung injury. New strategies against LEBD provide benefits in prevention and treatment of IAV. Previous studies showed that flavonoids (MHF), main bioactivity fraction derived from M. Herba, exerted anti-inflammatory and antiviral activities, but the underlying protection of MHF against IAV-induced acute lung injury remained obscure. The present study was to investigate the protection of MHF against IAV-induced LEBD in vivo and in vitro. MATERIALS AND METHODS Mice were intranasally challenged with IAV and orally administered with MHF for 5 days. The pulmonary hyperpermeability of infected mice was evaluated by Evans Blue staining and in vivo imaging. Serum levels of inflammatory cytokines and mediators were detected by ELISA assay. The transepithelial electrical resistance (TER) of human pulmonary microvascular endothelial cells (HPMVECs) was measured by using TER meter. The expressions of key proteins in NOX4-mediated NF-κB/MLCK pathways were determined by western blotting. RESULTS MHF treatment reduced lung index, W/D ratios, and serum levels of inflammatory factors (IL-6, TNF-α, IL-1β, PLA2, LBT4 and ICAM-1) in IAV-infected mice. Evans blue staining and in vivo imaging results revealed that MHF alleviated IAV-induced barrier dysfunction and pulmonary hyperpermeability. Moreover, luteolin and kaempferol, the main activity compounds in MHF, significantly inhibited TNF-α-induced HPMVEC apoptosis, and downregulated NF-κB/MLCK pathway by targeting NOX4. CONCLUSION MHF attenuated IAV-induced barrier dysfunction by suppressing NOX4/NF-κB/MLCK pathway and may serve as a potential agent for the prevention of LEBD and IAV.

Abstract
A series of plant-derived bioactive compounds belonging to the class of polyphenols, terpenes and capsaicinoids, interact with important pathophysiological pathways at a molecular, cellular and systemic level. Mechanisms of action include altering cell growth and differentiation, apoptosis, autophagy, inflammation, redox balance and metabolic and energy homeostasis. These effects might also involve the expression and function of Aquaporins (AQPs), a family of membrane channel proteins, involved in several body functions. The ultimate translational beneficial effect of such phytocompounds on AQPs in health and disease is a matter of intensive research. Results might provide novel therapeutic approaches to a number of human diseases. Here, we give an updated overview of this fast growing and promising field, discussing a number of phytocompounds and their action on AQPs and related potential clinical achievements.

Abstract
Background Artemisia scoparia Waldst and Kit is a famous traditional Chinese medicine widely distributed in Xinjiang, China. Flavonoids extracted from it exhibits inhibitory activities against several influenza virus strains. Despite this fact, the antiviral properties of CST, one of such flavonoids, against the influenza virus has not been reported. Thus, the aim of this study is to investigate the anti-influenza virus efficacy and antiviral mechanism of CST. Methods The inhibitory activity of CST against influenza viruses was assessed by using viral titers and performing Western blot, qRT-PCR, and immunofluorescence assays in Madin–Darby canine kidney (MDCK) cells and a human monocytic cell line (THP-1). The mechanism of CST against influenza virus was analyzed by hemagglutination inhibition (HI) assay, neuraminidase (NA) inhibition assay, and Western blot. Results CST reduced viral titers and influenza A virus (IAV) RNA and protein synthesis in a dose-dependent manner. Mechanistically, CST had no inhibitory effect on the attachment and release processes of the viral life cycle, as indicated by the HI and NA assays. Conversely, the CST-mediated inhibition of IAV is possibly linked to the inactivation of the NF-κB/p65 signal pathway. CST also suppressed the activation of JNK MAPK and P38 MAPK in vitro. In line with NF-κB/p65 inhibition, the expression levels of proinflammatory cytokines (TNF-α, IL-1β, IL-8, and IL-10) and the inflammation-related protein COX-2 were downregulated by CST. Conclusions CST inhibited IAV replication by downregulating the NF-κB signal transduction pathway. CST may be a potential agent or supplement against IAV infection.

Abstract
Plant-derived bioactive compounds have protective role for plants but may also modulate several physiological processes of plant consumers. In the last years, a wide spectrum of phytochemicals have been found to be beneficial to health interacting with molecular signaling pathways underlying critical functions such as cell growth and differentiation, apoptosis, autophagy, inflammation, redox balance, cell volume regulation, metabolic homeostasis, and energy balance. Hence, a large number of biologically active phytocompounds of foods have been isolated, characterized, and eventually modified representing a natural source of novel molecules to prevent, delay or cure several human diseases. Aquaporins (AQPs), a family of membrane channel proteins involved in many body functions, are emerging among the targets of bioactive phytochemicals in imparting their beneficial actions. Here, we provide a comprehensive review of this fast growing topic focusing especially on what it is known on the modulatory effects played by several edible plant and herbal compounds on AQPs, both in health and disease. Phytochemical modulation of AQP expression may provide new medical treatment options to improve the prognosis of several diseases.

Zhang HH, Yu WY, Li L, Wu F, Chen Q, Yang Y, Yu CH. Protective effects of diketopiperazines from Moslae Herba against influenza A virus-induced pulmonary inflammation via inhibition of viral replication and platelets aggregation. JOURNAL OF ETHNOPHARMACOLOGY 2018; 215:156-166. [PMID: 29309861 DOI: 10.1016/j.jep.2018.01.005] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2017] [Revised: 12/27/2017] [Accepted: 01/04/2018] [Indexed: 06/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Moslae Herba (MH) is broadly used as an antiviral, antipyretic and anticoagulant drug which effectively treats respiratory diseases including cough, asthma, throat, cold and flu. AIM OF THIS STUDY The excessive inflammation of the lungs is the hallmark of severe influenza A virus (IAV) infection, while platelet aggregation and its subsequent microvascular thrombosis can exacerbate IAV-induced lung injury. Thus, inhibition of platelet aggregation can be a potential target for IAV treatment. Previous studies focus on the flavonoids from MH and their anti-inflammatory activities, but the anticoagulant compounds and potential molecular mechanism of MH remains unclear. This study was to isolate and characterize diketopiperazines (DKPs) from MH and to explore the underlying anticoagulant mechanism on IAV infection models. MATERIALS AND METHODS EtOAc sub-extract separated from MH ethanolic extract was subjected to fractionation through column chromatography. The chemical structures of pure compounds were characterized by the spectral analysis. Antiviral activities of DKPs were assayed in IAV-infected Madin-Darby canine kidney (MDCK) cells and mice. Anticoagulant effects of DKPs were investigated on adenosine 5'-diphosphate (ADP)-induced acute pulmonary embolism and IAV-induced lung injury in vivo, as well as the inhibition on platelet activating factor (PAF), arachidonic acid (AA) and ADP-induced platelet aggregation in vitro. The serum levels of thromboxane B2 (TXB2) and 6-keto-PGF1α were detected by ELISA. The expressions of key proteins in CD41-mediated PI3K/AKT pathways were determined by western blotting analysis. RESULTS Six DKPs were, for the first time, isolated from MH and identified as cyclo(Tyr-Leu) (1), cyclo(Phe-Phe) (2), cyclo(Phe-Tyr) (3), cyclo(Ala-Ile) (4), cyclo(Ala-Leu) (5) and Bz-Phe-Phe-OMe (6). Among these DKPs, cyclo(Ala-Ile) and Bz-Phe-Phe-OMe possessed low cytotoxicities and significant inhibition against cytopathic effects induced by IAV (H1N1 and H3N2) replication in MDCK cells. Furthermore, cyclo(Ala-Ile) and Bz-Phe-Phe-OMe significantly alleviated IAV-induced platelet activation and lung inflammation in mice. They could reduce the expression of CD41 and the phosphorylation of PI3K and AKT in PLTs of IAV-infected mice. CONCLUSION These results suggested that cyclo(Ala-Ile) and Bz-Phe-Phe-OMe isolated from MH have antiviral and anticoagulant effects against IAV-induced PLT aggregation and lung inflammation via regulating CD41/PI3K/AKT pathway, and could be used as the potential agents for IAV treatment.

Int Forum Allergy Rhinol 2017; 8:64-71. [PMID: 29083535 DOI: 10.1002/alr.22035] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2017] [Revised: 10/05/2017] [Accepted: 10/08/2017] [Indexed: 12/31/2022]
Abstract
BACKGROUND Cholinergic stimulation plays a major role in inflammatory airway diseases. However, its role in airway surface liquid homeostasis and aquaporin 5 (AQP5) regulation remains unclear. In this study we sought to determine the effects of methacholine and dexamethasone on AQP5 expression in human nasal epithelial cells (HNEpC). METHODS HNEpC were cultured with methacholine or dexamethasone at 4 concentrations in vitro. The subcellular distribution of AQP5 was explored using immunocytochemistry. The pharmacologic effects of methacholine and dexamethasone on the expression of the phosphorylation of cyclic adenosine monophosphate-responsive element binding protein (p-CREB), AQP5, and nuclear factor-kappaB (NF-κB) were examined using Western blotting. RESULTS AQP5 was found to be located in cell membrane and cytoplasm and present in every group without a statistically significant difference. Methacholine inhibited expression of AQP5 and p-CREB in HNEpC, whereas dexamethasone increased these protein levels dose-dependently in a statistically significant manner. In turn, HNEpC treated with methacholine and dexamethasone showed the same trends as those intervened separately with these 2 drugs. Moreover, dexamethasone had the ability to reverse the inhibitory effect of methacholine. Western blotting revealed that, after incubation with 10-4 mol/L methacholine, NF-κB increased significantly, by 186.67%, compared with the untreated control group. Again, such an increase could be significantly reversed after dexamethasone treatment. CONCLUSION NF-κB activation is important for inhibition of p-CREB/AQP5 expression after methacholine intervention, and dexamethasone adjusts it to the opposite side. This observation could provide additional insight into the anti-inflammatory effects of glucocorticoids that contribute to maintaining airway surface liquid and mucosal defense.

Abstract
Acute exposure to hydrogen sulfide (H2S) poses a significant threat to life, and the lung is one of the primary target organs of H2S. However, the mechanisms involved in H2S-induced acute pulmonary edema are poorly understood. This study aims to investigate the effects of H2S on the expression of water channel aquaporin 5 (AQP5) and to elucidate the signaling pathways involved in AQP5 regulation. In an in vivo study, C57BL6 mice were exposed to sub-lethal concentrations of inhaled H2S, and histological injury of the lungs and ultrastructure injury of the epithelial cells were evaluated. With real-time PCR and western blot assays, we found that H2S exposure contributed to a significant decrease in AQP5 expression both in murine lung tissue and the A549 cell line, and the ERK1/2 and p38 MAPK signaling pathways were demonstrated to be implicated in AQP5 regulation. Therefore, adjusting AQP5 protein levels could be considered a therapeutic strategy for the treatment of APE induced by H2S and other hazardous gases.

[PMID: 27600871 PMCID: PMC5042776 DOI: 10.3892/mmr.2016.5713] [Citation(s) in RCA: 43] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2016] [Accepted: 09/01/2016] [Indexed: 11/09/2022] Open
Abstract
Atractylodis Rhizoma is a traditional medicinal herb, which has antibacterial, antiviral, anti-inflammatory and anti-allergic, anticancer, gastroprotective and neuroprotective activities. It is widely used for treating fever, cold, phlegm, edema and arthralgia syndrome in South-East Asian nations. In this study, 6 chemical compositions of Atractylodis Rhizoma were characterized by spectral analysis and their antiviral activities were evaluated in vitro and in vivo. Among them, atractylon showed most significant antiviral activities. Atractylon treatment at doses of 10–40 mg/kg for 5 days attenuated influenza A virus (IAV)-induced pulmonary injury and decreased the serum levels of interleukin (IL)-6, tumor necrosis factor-α and IL-1β, but increased interferon-β (IFN-β) levels. Atractylon treatment upregulated the expression of Toll-like receptor 7 (TLR7), MyD88, tumor necrosis factor receptor-associated factor 6 and IFN-β mRNA but downregulated nuclear factor-κB p65 protein expression in the lung tissues of IAV-infected mice. These results demonstrated that atractylon significantly alleviated IAV-induced lung injury via regulating the TLR7 signaling pathway, and may warrant further evaluation as a possible agent for IAV treatment.
