PHYTOCHEMICAL ANALYSIS : PCA 2024; 35:220-238. [PMID: 37735858 DOI: 10.1002/pca.3284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 08/31/2023] [Accepted: 09/02/2023] [Indexed: 09/23/2023]
Abstract
INTRODUCTION Shenlingbaizhu granule, a Traditional Chinese Medicine prescription comprising Renshen, Gancao, and Shanyao, is widely consumed in China nowadays. OBJECTIVE The study tries to propose pharmacopoeia quality markers (Q-markers) to prevent counterfeiting involving Renshen, Gancao, and Shanyao. METHODOLOGY A novel strategy, that is, library-based ultra-high-performance liquid chromatography-quadrupole-orbitrap mass spectrometry, was used to analyse the lyophilised aqueous powder of Shenlingbaizhu granule. Subsequently, quantum chemistry calculation and UV-vis spectra scanning were also performed through theoretical or experimental approaches. RESULT Thirty-two isomers have been strictly distinguished, especially positional isomeric isochlorogenic acid B versus isochlorogenic acid C, positional isomeric schaftoside versus isoschaftoside, positional isomeric ginsenoside Rg2 versus 20S-ginsenoside Rg3, and stereoisomeric 20S-ginsenoside Rg3 versus 20R-ginsenoside Rg3. Seventeen compounds were unexpectedly observed, particularly scoparone and pectolinarigenin, while a total of 76 bioactive compounds have been putatively identified in the study. The quantum chemistry calculation and UV-vis spectra scanning results revealed that glycyrrhizic acid, ginsenoside Re, ginsenoside Rb1, and diosgenin displayed different dipole moment values and maximum absorption wavelengths from each other. CONCLUSION The study recommends glycyrrhizic acid, ginsenoside Re, ginsenoside Rb1, and diosgenin as four anti-counterfeiting Q-markers for the pharmacopoeia. The anti-counterfeiting Q-markers can be detected using conventional HPLC. The observation of 17 unexpected compounds updates our knowledge regarding the bioactives of Shenlingbaizhu granule.

Discovery of antitussive material basis and mechanisms in Citri Sarcodactylis Fructus by coupling UHPLC-Q/Orbitrap HRMS combined spectrum-effect relationship and metabolomics analyses. J Chromatogr B Analyt Technol Biomed Life Sci 2024; 1233:123987.

Abstract
Citri Sarcodactylis Fructus (CSF) is widely used as food raw material and traditional Chinese medicine. Fingerprints of different fractions of CSF were established for spectrum-effect relationship analysis, and the main compounds were identified by UHPLC Quadrupole Orbitrap high-resolution mass spectrometry (UHPLC-Q/Orbitrap HRMS). The antitussive effect was evaluated using a classical mouse model of cough induced by ammonia water. One-way ANOVA was used to determine differences in efficacy. The potential active compounds were screened by spectrum-effect relationship with grey relational degree analysis (GRA), Pearson bivariate correlation analysis (Pearson's), and partial least squares analysis (PLS) analyses. Differential metabolites associated with cough in serum were screened and identified using orthogonal partial least squares-discriminant analysis, HMDB database, and UHPLC-Q/Orbitrap HRMS. Metabolic pathway analysis was performed using MetaboAnalyst 5.0. Results indicate that 70 % ethanol elution fraction (70 % EF) is the major active fraction, and 8 components were identified to possess antitussive effects. Metabolomic analysis showed that 19 metabolites are potential biomarkers related to cough, and 70 % EF can remarkable restore 13 of them to normal levels (P < 0.05). These biomarkers are mainly involved in glycerophospholipid metabolism and sphingolipid metabolism. This study aims to reveal the main pharmacodynamic active sites and potential active ingredients of CSF's antitussive effect. In addition, metabolomics was used to preliminarily elucidate the in-vivo regulatory mechanism of the antitussive effect of the 70 % EF of CSF.

Abstract
Natural products (NPs) continue to serve as a structural model for the development of new bioactive molecules and improve the process of identifying novel medicines. The biological effects of coumarins, one of the most researched compounds among NPs, are currently being thoroughly investigated. In the present investigation, we reported the synthesis of nineteen semi-synthetic 3-substituted scoparone analogues, followed by their characterization using analytical methods such as NMR, HPLC, and HRMS. All compounds screened for in vitro and in vivo study for their ability to reduce inflammation. The SAR study worked effectively for this particular scoparone 3-substitution, as compounds 3, 4, 9, 16, 18, and 20 displayed improved in vitro results for TNF-α than the parent molecule. Similarly, compounds 3, and 17 showed a higher percentage of IL-6 inhibition. Compounds 3, 4, and 12 have also been identified by in vivo studies as promising candidates with higher percent inhibition than the parent scoparone molecule. As evident from all in vitro and in vivo studies, compound 3 showed the most potent anti-inflammatory activity among all.

J Cell Mol Med 2021; 25:3136-3148. [PMID: 33560596 PMCID: PMC7957216 DOI: 10.1111/jcmm.16304] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2020] [Revised: 11/13/2020] [Accepted: 01/04/2021] [Indexed: 12/22/2022] Open
Abstract
Long‐term poorly controlled myocardial hypertrophy often leads to heart failure and sudden death. Activation of ras‐related C3 botulinum toxin substrate 1 (RAC1) by angiotensin II (Ang II) plays a pivotal role in myocardial hypertrophy. Previous studies have demonstrated that scoparone (SCO) has beneficial effects on hypertension and extracellular matrix remodelling. However, the function of SCO on Ang II‐mediated myocardial hypertrophy remains unknown. In our study, a mouse model of myocardial hypertrophy was established by Ang II infusion (2 mg/kg/day) for 4 weeks, and SCO (60 mg/kg bodyweight) was administered by gavage daily. In vitro experiments were also performed. Our results showed that SCO could alleviate Ang II infusion‐induced cardiac hypertrophy and fibrosis in mice. In vitro, SCO treatment blocks Ang II‐induced cardiomyocyte hypertrophy, cardiac fibroblast collagen synthesis and differentiation to myofibroblasts. Meanwhile, we found that SCO treatment blocked Ang II‐induced oxidative stress in cardiomyocytes and cardiac fibroblasts by inhibiting RAC1‐GTP and total RAC1 in vivo and in vitro. Furthermore, reactive oxygen species (ROS) burst by overexpression of RAC1 completely abolished SCO‐mediated protection in cardiomyocytes and cardiac fibroblasts in vitro. In conclusion, SCO, an antioxidant, may attenuate Ang II‐induced myocardial hypertrophy by suppressing of RAC1 mediated oxidative stress.

Abstract
Botanicals have a long history of medicinal use for a multitude of ailments, and many modern pharmaceuticals were originally isolated from plants or derived from phytochemicals. Among these, artemisinin, first isolated from Artemisia annua, is the foundation for standard anti-malarial therapies. Plants of the genus Artemisia are among the most common herbal remedies across Asia and Central Europe. The species Artemisia scoparia (SCOPA) is widely used in traditional folk medicine for various liver diseases and inflammatory conditions, as well as for infections, fever, pain, cancer, and diabetes. Modern in vivo and in vitro studies have now investigated SCOPA's effects on these pathologies and its ability to mitigate hepatotoxicity, oxidative stress, obesity, diabetes, and other disease states. This review focuses on the effects of SCOPA that are particularly relevant to metabolic health. Indeed, in recent years, an ethanolic extract of SCOPA has been shown to enhance differentiation of cultured adipocytes and to share some properties of thiazolidinediones (TZDs), a class of insulin-sensitizing agonists of the adipogenic transcription factor PPARγ. In a mouse model of diet-induced obesity, SCOPA diet supplementation lowered fasting insulin and glucose levels, while inducing metabolically favorable changes in adipose tissue and liver. These observations are consistent with many lines of evidence from various tissues and cell types known to contribute to metabolic homeostasis, including immune cells, hepatocytes, and pancreatic beta-cells. Compounds belonging to several classes of phytochemicals have been implicated in these effects, and we provide an overview of these bioactives. The ongoing global epidemics of obesity and metabolic disease clearly require novel therapeutic approaches. While the mechanisms involved in SCOPA's effects on metabolic, anti-inflammatory, and oxidative stress pathways are not fully characterized, current data support further investigation of this plant and its bioactives as potential therapeutic agents in obesity-related metabolic dysfunction and many other conditions.

Abstract
Since the outbreak of coronavirus disease 2019 (COVID-19) in December 2019, millions of people have been infected and died worldwide. However, no drug has been approved for the treatment of this disease and its complications, which urges the need for finding novel therapeutic agents to combat. Among the complications due to COVID-19, lung injury has attained special attention. Besides, phytochemicals have shown prominent anti-inflammatory effects and thus possess significant effects in reducing lung injury caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Also, the prevailing evidence reveales the antiviral effects of those phytochemicals, including anti-SARS-CoV activity, which could pave the road in providing suitable lead compounds in the treatment of COVID-19. In the present study, candidate phytochemicals and related mechanisms of action have been shown in the treatment/protection of lung injuries induced by various methods. In terms of pharmacological mechanism, phytochemicals have shown potential inhibitory effects on inflammatory and oxidative pathways/mediators, involved in the pathogenesis of lung injury during COVID-19 infection. Also, a brief overview of phytochemicals with anti-SARS-CoV-2 compounds has been presented.

Abstract
The aim of this study was to investigate the role of scoparone (SCO) in hepatic fibrosis. For this, we conducted in vivo and in vitro experiments. In vivo rats that were divided into six groups, control, carbon tetrachloride, and colchicine, as well as SCO groups, SCO50, SCO100, and SCO200 treated with 50, 100, and 200 mg/kg SCO doses, respectively. Furthermore, SCO was shown to inhibit Toll-like receptor-4 (TLR-4)/nuclear factor kappa-B (NF-κB; TLR-4/NF-κB) signals by inhibiting TLR-4, which in turn downregulates the expression of MyD88, promotes NF-κB inhibitor-α, NF-κB inhibitor-β, and NF-κB inhibitor-ε activation, while inhibiting NF-κB inhibitor-ζ. Subsequently, the decrease of phosphorylation of nuclear factor-κB levels leads to the downregulation of the downstream inflammatory factors' tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1 beta, thus weakening hepatic fibrosis. Notably, the SCO200 treated group presented the most significant improvement. Hence, we conclude that SCO alleviates hepatic fibrosis by inhibiting TLR-4/NF-κB signals.

Abstract
In the present study, a polyphenolic mixture was isolated from Seomae mugwort (SM; a native Korean variety of Artemisia argyi H.) via extraction with aqueous 70% methanol followed by the elution of ethyl acetate over a silica gel column. Each polyphenolic compound was analyzed using high-performance liquid chromatography coupled with tandem mass spectrometry, and compared with the literature. In addition to the 14 characterized components, one hydroxy-cinnamate, six flavonoids, and one lignan were reported for the first time, to the best our knowledge, in Artemisia argyi H. The anti-inflammatory properties of SM polyphenols were studied in lipopolysaccharide-treated RAW 264.7 macrophage cells. The SM polyphenols attenuated the activation of macrophages via the inhibition of nitric oxide production, nuclear factor-κB activation, the mRNA expression of inducible nitric oxide synthase, tumor necrosis factor α and interleukin-1β, and the phosphorylation of mitogen-activated protein kinase. Our results suggested that SM polyphenols may have therapeutic potential for the treatment of inflammatory-related diseases.

Jung SH, Lee GB, Ryu Y, Cui L, Lee HM, Kim J, Kim B, Won KJ. Inhibitory effects of scoparone from chestnut inner shell on platelet-derived growth factor-BB-induced vascular smooth muscle cell migration and vascular neointima hyperplasia. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2019; 99:4397-4406. [PMID: 30861122 DOI: 10.1002/jsfa.9674] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Revised: 02/03/2019] [Accepted: 03/06/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Compounds of the inner shell of chestnut (Castanea crenata) have diverse biological activities, including anti-cancer and anti-oxidant activities. Here we explored the effects of an extract of chestnut inner shells and of its bioactive component scoparone on vascular smooth muscle cell migration and vessel damage. RESULTS The ethanol extract of chestnut inner shells, containing 11 major compounds, inhibited platelet-derived growth factor (PDGF)-BB-induced migration of rat aortic smooth muscle cells (RASMCs). Among these compounds, scoparone (6,7-dimethoxycoumarin) suppressed RASMC migration and wound healing in response to PDGF-BB but did not affect RASMC proliferation. In RASMCs, scoparone inhibited the PDGF-BB-induced rat aortic sprout outgrowth and attenuated the PDGF-BB-mediated increase in phosphorylation of mitogen-activated protein kinases (MAPKs), p38 MAPK and extracellular signal-regulated kinase 1/2. The in vivo administration of scoparone resulted in the attenuation of neointima formation in balloon-injured carotid arteries of rats. CONCLUSION These findings demonstrate that scoparone, found in chestnut inner shells, may inhibit cell migration through suppression of the phosphorylation of MAPKs in PDGF-BB-treated RASMCs, probably contributing to the reduction of neointimal hyperplasia induced after vascular injury. Therefore, scoparone and chestnut inner shell may be a potential agent or functional food, respectively, for the prevention of vascular disorders such as vascular restenosis or atherosclerosis. © 2019 Society of Chemical Industry.

Abstract
The expression of cytochrome P4501A1 (CYP1A1) enzyme is changed in various organs during the host response to inflammation or infection, leading to alterations in the metabolism of endogenous and exogenous compounds. Results of this study showed that CYP1A1 expression was significantly downregulated in the mammary tissue of bovine with mastitis, in inflammatory epithelial cells (INEs) extracted from the tissue, and in lipopolysaccharide- (LPS-) induced INEs compared with their corresponding counterparts. Overexpression of CYP1A1 in bovine mammary epithelial cells alleviated the LPS-induced inhibition of epithelial proliferation, abated the LPS-induced increase of gene expression and protein secretion of inflammatory cytokine tumor necrosis factor-α and interleukin-6, and attenuated the LPS-induced activation of NF-κB signaling. These findings suggest that CYP1A1 has immense potential in the regulation of inflammatory responses in bovine mammary epithelial cells during mastitis and may serve as a useful therapeutic target in mitigating injuries caused by inflammatory overreaction.

Abstract
Epilepsy is a common and devastating neurological disorder. Inflammatory processes and apoptosis in brain tissue have been reported in human epilepsy. Scoparone (6,7-dimethoxycoumarin) is an important chemical substance, which has multiple beneficial activities, including antitumor, anti-inflammatory and anti-coagulant properties. In our present study, we attempted to investigate if scoparone could attenuate seizures-induced blood brain barrier breakdown, inflammation and apoptosis. Pilocarpine (Pilo) and methylscopolamine were used to establish acute seizure animal model. Scoparone suppressed the leakage of blood brain barrier, inflammation and apoptosis. In hippocampus and cortex, the expression of inflammation-associated molecules, such as chemokine (CXC motif) ligand 1 (CXCL-1), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), IL-6, hypoxia-inducible factor 1α (HIF-1α), and monocyte chemoattractant protein-1 (MCP-1), were reduced by scoparone through inactivating toll-like receptor 4/nuclear factor-kappa B (TLR4/NF-κB) pathway. Scoparone reduced apoptotic levels in hippocampus by TUNEL analysis, along with decreased Caspase-3 and PARP cleavage. In addition, phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) pathway in Pilo-induced acute seizures was also inactivated by scoparone. In vitro, we confirmed that scoparone inhibited LPS-caused astrocytes activation as proved by the reduced glial fibrillary acidic protein (GFAP) levels, inflammation and apoptosis, which were at least partly dependent on AKT suppression. The results above indicated that scoparone could relieve pilocarpine (Pilo)-induced seizures against neural cell inflammation and apoptosis.

Abstract
Acute lung injury (ALI) is characterized by inflammation of the lung tissue and oxidative injury caused by excessive accumulation of reactive oxygen species. Studies have suggested that anti-inflammatory or antioxidant agents could be used for the treatment of ALI with a good outcome. Therefore, our study aimed to test whether the mycelium extract of Sanghuangporus sanghuang (SS-1), believed to exhibit antioxidant and anti-inflammatory properties, could be used against the excessive inflammatory response associated with lipopolysaccharides (LPS)-induced ALI in mice and to investigate its possible mechanism of action. The experimental results showed that the administration of SS-1 could inhibit LPS-induced inflammation. SS-1 could reduce the number of inflammatory cells, inhibit myeloperoxidase (MPO) activity, regulate the TLR4/PI3K/Akt/mTOR pathway and the signal transduction of NF-κB and MAPK pathways in the lung tissue, and inhibit high mobility group box-1 protein 1 (HNGB1) activity in BALF. In addition, SS-1 could affect the synthesis of antioxidant enzymes Heme oxygenase 1 (HO-1) and Thioredoxin-1 (Trx-1) in the lung tissue and regulate signal transduction in the KRAB-associated protein-1 (KAP1)/nuclear factor erythroid-2-related factor Nrf2/Kelch Like ECH associated Protein 1 (Keap1) pathway. Histological results showed that administration of SS-1 prior to induction could inhibit the large-scale LPS-induced neutrophil infiltration of the lung tissue. Therefore, based on all experimental results, we propose that SS-1 exhibits a protective effect against LPS-induced ALI in mice. The mycelium of S. sanghuang can potentially be used for the treatment or prevention of inflammation-related diseases.

Abstract
Microglia activation and the release of various inflammatory cytokines are largely related to neurological diseases, including Parkinson’s, Alzheimer’s, and other brain diseases. The suppression of microglial cells using natural bioactive compounds has become increasingly important for brain therapy owing to the expected beneficial effect of lower toxicity. Scoparone (6,7-dimethoxycoumarin), a major bioactive compound found in various plant parts, including the inner shell of chestnut (Castanea crenata), was evaluated on lipopolysaccharide (LPS)-activated BV-2 microglia cells. The results indicated that scoparone suppresses the LPS-stimulated increase of neuroinflammatory responses and inhibited the pro-inflammatory cytokine production in the BV-2 microglial cells. A mechanistic study showed that scoparone specifically inhibited the LPS-stimulated activation via a major regulation of IRF-3 and a regulation of ERK, whereby the phosphorylation in the BV-2 microglial cells is blocked. These data suggest that scoparone has anti-neuroinflammatory effects in LPS-activated BV-2 microglial cells, and could possibly be used in the development of novel drugs for the prevention and treatment of neuroinflammatory diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kegan Liyan oral liquid (KGLY), a Chinese prescription modified from classic formulas Yin-Qiao-San (from TCM classic Wenbing Tiaobian) and Shen-Jie-San (first mentioned in Shanghan Wenyi Tiaobian), has been reported to exert heat-clearing and detoxifying effects and used extensively for the treatment of severe pulmonary diseases in clinics including influenza, cough and pneumonia. AIM OF THIS STUDY The purpose of this study was to investigate the protective effect of KGLY on lipopolysaccharide (LPS) induced acute lung injury (ALI) in mice and to illuminate the underlying mechanisms. MATERIALS AND METHODS Mice were orally administrated with KGLY (50, 100 and 150mg/kg) before intratracheal instillation of LPS. 24h post LPS challenge, lung tissues and the bronchoalveolar lavage fluid (BALF) were collected for lung wet/dry (W/D) weight ratio, histopathological examinations and biochemical analyses. The cell counts, protein concentration, interleukin-1β (IL-1β), interleukin-6 (IL-6), necrosis factor-α (TNF-α), macrophage inflammatory protein-2 (MIP-2) in BALF, superoxide dismutase (SOD), glutathione (GSH), myeloperoxidase (MPO) and malondialdehyde (MDA) levels were detected. Meanwhile, the activation of toll-like receptor 4 (TLR4), nuclear factor kappa B (NF-κB), as well as matrix metalloproteinases 9 (MMP-9) were determined by western blot assay. RESULTS KGLY significantly prolonged mice survival time and ameliorated LPS-induced edema, thickening of alveolar septa and inflammatory cell infiltration in a dose-dependent manner. Additionally, KGLY markedly attenuated LPS-induced acute pulmonary inflammation via decreasing the expressions of cytokines and chemokines (IL-1β, IL-6, TNF-α, and MIP-2), enhanced the activities of anti-oxidative indicators (SOD and GSH), suppressed the levels of MPO and MDA, and down-regulated the expressions of TLR4, NF-κB and MMP9. CONCLUSIONS The results suggested that the relieving effect of KGLY against LPS-induced ALI might be partially due to suppression of oxidative stress and inflammatory response, inhibition of TLR4-mediated NF-κB activation, and down-regulation of MMP9 expression, indicating it may be a potential therapeutic agent for ALI.

Abstract
Diospyros lotus is traditionally used for the treatment of diabetes, diarrhea, tumor, and hypertension. The purpose of this study was to investigate the anti-inflammatory effect and underlying molecular mechanisms of myricetin in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Myricetin dose-dependently suppressed the production of pro-inflammatory mediators (NO, iNOS, PGE2, and COX-2) in LPS-stimulated RAW264.7 macrophages. Myricetin administration decreased the production of NO, iNOS, TNF-α, IL-6, and IL-12 in mice. Myricetin decreased NF-κB activation by suppressing the degradation of IκBα, nuclear translocation of p65 subunit of NF-κB, and NF-κB DNA binding activity in LPS-stimulated RAW264.7 macrophages. Moreover, myricetin attenuated the phosphorylation of STAT1 and the production of IFN-β in LPS-stimulated RAW264.7 macrophages. Furthermore, myricetin induced the expression of HO-1 through Nrf2 translocation. In conclusion, these results suggest that myricetin inhibits the production of pro-inflammatory mediators through the suppression of NF-κB and STAT1 activation and induction of Nrf2-mediated HO-1 expression in LPS-stimulated RAW264.7 macrophages.

Abstract
In this study, we found that chloroform fraction (CF) from TJP ethanolic extract inhibited lipopolysaccharide (LPS)-induced production of nitric oxide (NO) and intracellular ROS in RAW264.7 cells. In addition, expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) genes was reduced, as evidenced by western blot. Our results indicate that CF exerts anti-inflammatory effects by down-regulating expression of iNOS and COX-2 genes through inhibition of MAPK (ERK, JNK and p38) and NF-κB signaling. Similarly we also evaluated the effects of CF on LPS-induced acute lung injury. Male Balb/c mice were pretreated with dexamethasone or CF 1 h before intranasal instillation of LPS. Eight hours after LPS administration, the inflammatory cells in the bronchoalveolar lavage fluid (BALF) were determined. The results indicated that CF inhibited LPS-induced TNF-α and IL-6 production in a dose dependent manner. It was also observed that CF attenuated LPS-induced lung histopathologic changes. In conclusion, these data demonstrate that the protective effect of CF on LPS-induced acute lung injury (ALI) in mice might relate to the suppression of excessive inflammatory responses in lung tissue. Thus, it can be suggested that CF might be a potential therapeutic agent for ALI.

[PMID: 26072062 DOI: 10.1016/j.intimp.2015.05.051] [Citation(s) in RCA: 74] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2015] [Revised: 05/26/2015] [Accepted: 05/31/2015] [Indexed: 11/22/2022]
Abstract
Acute lung injury (ALI) has a high morbidity and mortality rate due to the serious inflammation and edema occurred in lung. Magnolol extracted from Magnolia officinalis, has been reported to exhibit anti-inflammatory, and antioxidant activities. Peroxisome proliferator-activated receptors (PPARs) are known to exert a cytoprotective effect against cellular inflammatory stress and oxidative injury. The aim of this study was to explore the involvement of PPAR-γ in the beneficial effect of magnolol in lipopolysaccharide (LPS)-induced ALI. We found that treatment with magnolol greatly improved the pathological features of ALI evidenced by reduction of lung edema, polymorphonuclear neutrophil infiltration, ROS production, the levels of pro-inflammatory cytokines in bronchoalveolar lavage fluid (BALF), the expression of iNOS and COX-2, and NF-κB activation in lungs exposed to LPS. Importantly, magnolol is capable of increasing the PPAR-γ expression and activity in lungs of ALI. However, blocking PPAR-γ activity with GW9662 markedly abolished the protective and anti-inflammatory effects of magnolol. Taken together, the present study provides a novel mechanism accounting for the protective effect of magnolol in LPS-induced ALI is at least partly attributed to induction of PPAR-γ in lungs, and in turn suppressing NF-κB-related inflammatory responses.

Abstract
Jolkinolide B (JB), an ent-abietane diterpenoid, isolated from the dried root of Euphorbia fischeriana, has been reported to have potent anti-tumor and anti-inflammatory activities. However, the effects of JB on acute lung injury (ALI) and underlying molecular mechanisms have not been investigated. The present study aimed to investigate the effect of JB on lipopolysaccharide (LPS)-induced ALI. Male C57BL/6 mice were pretreated with dexamethasone or JB 1h before intranasal instillation of LPS. The results showed that JB markedly attenuated LPS-induced histological alterations, lung edema, inflammatory cell infiltration, myeloperoxidase (MPO) activity as well as the production of TNF-α, IL-6 and IL-1β. Furthermore, JB also significantly inhibited LPS-induced the degradation of IκBα and phosphorylation of NF-κB p65 and MAPK. Therefore, our study provides the first line of evidence that pretreatment of JB has a protective effect on LPS-induced ALI in mice. The anti-inflammatory mechanism of JB may be attributed to its suppression of NF-κB and MAPK activation.

Eucalyptol suppresses matrix metalloproteinase-9 expression through an extracellular signal-regulated kinase-dependent nuclear factor-kappa B pathway to exert anti-inflammatory effects in an acute lung inflammation model.

Abstract
Abstract
Objectives
The acute lung injury (ALI) model is characterised by a severe acute inflammatory response in the lungs that represents the pathogenesis of acute respiratory distress syndrome (ARDS). In this study, we sought to elucidate the anti-inflammatory mechanism of eucalyptol in relation to tissue remodelling in acute lung inflammation.
Methods
BALB/C mice were intraperitoneally injected with eucalyptol (100, 200 or 400 mg/kg) or dexamethasone (1 mg/kg) 1 h before intratracheal challenge with lipopolysaccharide (LPS; 1.5 mg/kg) and sacrificed after 4 h. The anti-inflammatory effects of eucalyptol were assessed by determining cell counts, measuring cytokine and nitric oxide production and performing Western blotting and histological analyses.
Key findings
Eucalyptol attenuated inflammation-associated increases in cell numbers, matrix metalloproteinase-9 (MMP-9) expression, production of cytokines (tumour necrosis factor-α and interleukin-6) and nitric oxide, and nuclear factor-kappa B (NF-κB) and phosphorylated extracellular signal-regulated kinase protein levels induced by LPS in bronchoalveolar lavage fluid from ALI mice. Furthermore, pretreatment with 400 mg/kg eucalyptol prevented LPS-induced histopathological changes. Collectively, these results indicate that eucalyptol acts through a mechanism involving decreased MMP-9 expression and an extracellular signal-regulated kinase-dependent NF-κB pathway to exert anti-inflammatory actions in acute lung inflammation.
Conclusions
Thus, eucalyptol may be a potentially important agent in the treatment of pulmonary inflammation.

Abstract
This study investigated the gastroprotective efficacy of synthesized scoparone derivatives on experimentally induced gastritis and their toxicological safety. Six scoparone derivatives were synthesized and screened for gastroprotective activities against HCl/ethanol- and indomethacin-induced gastric ulcers in rats. Among these compounds, 5,6,7-trimethoxycoumarin and 6,7,8-trimethoxycoumarin were found to have gastroprotective activity greater than the standard drug rebamipide; 6-methoxy-7,8-methylenedioxycoumarin, 6-methoxy-7,8-(1-methoxy)-methylenedioxycoumarin, 6,7-methylenedioxycoumarin, and 6,7-(1-methoxy)-methylenedioxycoumarin were found to be equipotent or less potent that of rebamipide. Pharmacological studies suggest that the presence of a methoxy group at position C-5 or C-8 of the scoparone's phenyl ring significantly improves gastroprotective activity, whereas the presence of a dioxolane ring at C-6, C-7, or C-8 was found to have decreased activity. In order to assess toxicological safety, two of the potent gastroprotective scoparone derivatives-5,6,7-trimethoxycoumarin and 6,7,8-trimethoxycoumarin-were examined for their acute toxicity in mice as well as their effect on cytochrome P450 (CYP) enzyme activity. These two compounds showed low acute oral toxicity in adult male and female mice, and caused minimal changes to CYP3A4 and CYP2C9 enzyme activity. These results indicate that compared to other scoparone derivatives, 5,6,7-trimethoxycoumarin and 6,7,8-trimethoxycoumarin can improve gastroprotective effects, and they have low toxicity and minimal effects on drug-metabolizing enzymes.

Abstract
OBJECTIVE The present study aimed to investigate the combined effects of puerarin with edaravone on inhalation lung injury induced by black gunpowder smog. MATERIALS AND METHODS Male Wistar rats were divided into five groups (control group, edaravone group, puerarin group, edaravone combined with puerarin group and inhalation group). The severity of pulmonary injuries was evaluated after inducing acute lung injury. Arterial blood gas, inflammatory cytokines, biochemical, parameters, cell counting, W/D weight ratio and histopathology were analyzed. Results in lung tissues, either edaravone or puerarin treatment alone showed significant protective effects against neutrophil infiltration and tissue injury, as demonstrated by myeloperoxidase activity and histopathological analysis (all p<0.05). In addition, combined treatment with both edaravone and puerarin demonstrated additive protective effects on smog-induced lung injury, compared with single treatment. CONCLUSIONS Combination of edaravone and puerarin shows promise as a new treatment option for acute lung injury/acute respiratory distress syndrome patients.

Apigenin-7-glycoside prevents LPS-induced acute lung injury via downregulation of oxidative enzyme expression and protein activation through inhibition of MAPK phosphorylation. Int J Mol Sci 2015; 16:1736-54.

Abstract
Apigenin-7-glycoside (AP7Glu) with multiple biological activities is a flavonoid that is currently prescribed to treat inflammatory diseases such as upper respiratory infections. Recently, several studies have shown that its anti-inflammatory activities have been strongly linked to the inhibition of secretion of pro-inflammatory proteins, such as inducible nitric oxide synthase (iNOs) and cyclooxygenase-2 (COX-2) induced through phosphorylation nuclear factor-κB (NF-κB) and mitogen-activated protein kinases (MAPK) pathways. Additionally, inflammation, which can decrease the activities of antioxidative enzymes (AOEs) is also observed in these studies. At the same time, flavonoids are reported to promote the activities of heme oxygenase-1 (HO-1) decreased by LPS. The purpose of this study was to assess these theories in a series of experiments on the suppressive effects of AP7Glu based on LPS-induced nitric oxide production in RAW264.7 macrophages in vitro and acute lung injury in mice in vivo. After six hours of lipopolysaccharide (LPS) stimulation, pulmonary pathological, myeloperoxidase (MPO) activity, total polymorphonuclear leukocytes (PMN) cells, cytokines in bronchoalveolar lavage fluid (BALF) and AOEs, are all affected and changed. Meanwhile, our data revealed that AP7Glu not only did significantly inhibit the LPS-enhanced inflammatory activity in lung, but also exhibited anti-inflammatory effect through the MAPK and inhibitor NF-κB (IκB) pathways.
