Hydroalcoholic extract from Sechium edule (Jacq.) S.w. root reverses oleic acid-induced steatosis and insulin resistance in vitro. Heliyon 2024; 10:e24567. [PMID: 38312619 PMCID: PMC10835324 DOI: 10.1016/j.heliyon.2024.e24567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 12/17/2023] [Accepted: 01/10/2024] [Indexed: 02/06/2024] Open
Abstract
Steatosis is characterized by fat accumulation and insulin resistance (IR) in hepatocytes, which triggers a pro-oxidant, pro-inflammatory environment that may eventually lead to cirrhosis or liver carcinoma. This work was aimed to assess the effect of Sechium edule root hydroalcoholic extract (rSe-HA) (rich in cinnamic and coumaric acid, among other phenolic compounds) on triglyceride esterification, lipid degradation, AMPK expression, and the phosphorylation of insulin receptor in a Ser312 residue, as well as on the redox status, malondialdehyde (MDA) production, and the production of proinflammatory cytokines in an in vitro model of steatosis induced by oleic acid, to help develop a phytomedicine that could reverse this pathology. rSe-HA reduced triglyceride levels in hepatocyte lysates, increased lipolysis by activating AMPK at Thr172, and improved the redox status, as evidenced by the concentration of glycerol and formazan, respectively. It also prevented insulin resistance (IR), as measured by glucose consumption and the phosphorylation of the insulin receptor at Ser312. It also prevented TNFα and IL6 production and decreased the levels of MDA and nitric oxide (ON). Our results indicate that rSe-HA reversed steatosis and controlled the proinflammatory and prooxidant environment in oleic acid-induced dysfunctional HepG2 hepatocytes, supporting its potential use to control this disorder.

Attenuation of CFA-induced arthritis through regulation of inflammatory cytokines and antioxidant mechanisms by Solanum nigrum L. leaves extracts. Inflammopharmacology 2023; 31:3281-3301. [PMID: 37864683 DOI: 10.1007/s10787-023-01357-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 09/25/2023] [Indexed: 10/23/2023]
Abstract
Solanum nigrum L. is a popular traditional medicine for various inflammatory conditions including rheumatism and joint pain. The current study aimed to evaluate the anti-arthritic mechanism of Solanum nigrum L. Four extracts were prepared using n-hexane, methanol, chloroform, and water. The anti-nociceptive and anti-inflammatory activity was carried out with 100, 200, and 300 mg/kg body wt. PO of each extract by the hot plate and carrageenan-induced paw oedema methods, respectively. The anti-arthritic study was performed with chloroform and aqueous extracts (300 mg/kg) in complete Freund's adjuvant (CFA)-induced arthritis. Paw size (mm), ankle joint diameter (mm), and latency time (sec) were recorded on day 0 and every 4th day till 28 days. The hematological, inflammatory, and oxidative biomarkers were estimated. Results showed that significant analgesia (p < 0.05) and reduction in paw inflammation were achieved with all extracts. The highest percent inhibition in Carrageenan-induced inflammation was achieved with 300 mg/kg of chloroform (72.19%) and aqueous (71.30%) extracts, respectively. In the CFA model, both extracts showed a significant reduction in paw size and ankle joint diameter (p < 0.05). The RT-qPCR analysis revealed the upregulation of interleukin-4 and interleukin-10, and down-expression of interleukin-1β, interleukin-6, tumor necrosis factor-α, cycloxygenase-2, nuclear factor-κB, prostaglandin E synthase 2, and interferon-γ. A significant increase in superoxide dismutase, catalase, and glutathione levels was observed. Hence, it is concluded that Solanum nigrum L. leaf extracts regulate the expression of inflammatory markers and improve oxidative stress resulting in the attenuation of CFA-induced arthritis.

Abstract
The current study utilizes a comprehensive network pharmacology and metabolomics analysis to investigate the mechanism of action of Ma-Mu-Ran Antidiarrheal Capsules (MMRAC) for the treatment of ulcerative colitis (UC). In this study, we established a mouse model of UC using dextran sulfate sodium. Colonic tissues were collected from mice and then subjected to hematoxylin and eosin staining, as well as histopathological analysis, to assess the therapeutic effect of MMRAC. Furthermore, we assessed the mechanisms through which MMRAC combats UC by employing integrated metabolomics and network pharmacology strategies. Lastly, we validated the key targets identified through western blot and molecular docking. An integrated network of metabolomics and network pharmacology was constructed using Cytoscape to identify eight endogenous metabolites involved in the therapeutic action of MMRAC on UC. Further comprehensive analyses were focused on four key targets and their associated core metabolites and pathways. The results of western blot and molecular docking demonstrated that MMRAC could modulate key targets and their expression levels. The cumulative results indicated that MMRAC restored intestinal function in UC, reduced inflammatory responses, and alleviated oxidative stress by influencing the methionine and cysteine metabolic pathways, as well as the urea cycle. In addition, it had an impact on arginine, proline, glutamate, aspartate, and asparagine metabolic pathways and their associated targets.

Anti-oxidant response of lipidom modulates lipid metabolism in Caenorhabditis elegans and in OxLDL-induced human macrophages by tuning inflammatory mediators. Biomed Pharmacother 2023; 160:114309. [PMID: 36709598 DOI: 10.1016/j.biopha.2023.114309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Revised: 01/17/2023] [Accepted: 01/25/2023] [Indexed: 01/29/2023] Open
Abstract
Atherosclerosis is the main pathological process of several cardiovascular diseases. It may begin early in life and stay latent and asymptomatic for an extended period before its clinical manifestation. The formation of foamy macrophages due to dysregulated lipid metabolism is a key event in the development and progression of atherosclerotic plaque. The current pharmacotherapy for atherosclerosis is not able to address multiple aetiologies associated with the disease. Lipidom, an herbal prescription medicine, has anti-oxidant, lipid lowering and anti-inflammatory properties that lead to multifaceted treatment benefits against chronic inflammation, dyslipidaemia, and oxidative stress. The present study aimed to characterize the pharmacological effects of Lipidom using various experimental models. The phytochemical analysis of Lipidom was performed on ultra-high performance liquid chromatography (UHPLC) platform. Lipidom was evaluated for cytosafety, IL-1β and MCP-1 release, modulation of NLRP3 pathway, NFκB activity, ROS generation, lipid accumulation and gene expression in THP1 macrophages. Furthermore, Lipidom evaluation was also performed in the N2, CF1553, and TJ356 strains of Caenorhabditis elegans (C. elegans). The evaluation of brood size, adult (%), lipid accumulation, triglyceride levels, SOD-3 GFP signal, MDA formation, DAF-16 nuclear translocation, and gene expression was performed in C. elegans. Lipidom treatment significantly reduced the inflammatory mediators, lipid accumulation, oxidative stress, and normalized genes involved in the development of foamy macrophages. Lipidom treated C. elegans showed a significant decline in lipid accumulation and oxidative stress. Taken together, Lipidom treatment showed a multifaceted approach in the modulation of several mediators responsible for the development and progression of atherosclerotic plaque.

Abstract
Natural products can generally exhibit a variety of biological activities, but most show mediocre performance in preliminary activity evaluation. Natural products often require structural modification to obtain promising lead compounds. Cinnamic acid (CA) is readily available and has diverse biological activities and low cytotoxicity. Introducing CA into natural products may improve their performance, enhance biological activity, and reduce toxic side effect. Herein, we aimed to discuss related applications of CA in the structural modification of natural products and provide a theoretical basis for future derivatization and drug development of natural products. Published articles, web databases (PubMed, Science Direct, SCI Finder, and CNKI), and clinical trial websites (https://clinicaltrials.gov/) related to natural products and CA derivatives were included in the discussion. Based on the inclusion criteria, 128 studies were selected and discussed herein. Screening natural products of CA derivatives allowed for classification by their biological activities. The full text is organized according to the biological activities of the derivatives, with the following categories: anti-tumor, neuroprotective, anti-diabetic, anti-microbial, anti-parasitic, anti-oxidative, anti-inflammatory, and other activities. The biological activity of each CA derivative is discussed in detail. Notably, most derivatives exhibited enhanced biological activity and reduced cytotoxicity compared with the lead compound. CA has various advantages and can be widely used in the synthesis of natural product derivatives to enhance the properties of drug candidates or lead compounds.

PLANTS (BASEL, SWITZERLAND) 2023; 12:plants12030613. [PMID: 36771695 PMCID: PMC9919988 DOI: 10.3390/plants12030613] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 01/20/2023] [Accepted: 01/27/2023] [Indexed: 06/01/2023]
Abstract
Various species of the genus Achillea L. (Asteraceae) are traditionally used worldwide for wound healing against diarrhea, flatulence, and abdominal pains, as diuretic and emmenagogue agents. In the present study, the essential oils (EOs) obtained separately from the leaves and inflorescences of wild-growing Achillea grandifolia Friv. from Mt. Menoikio and Mt. Pelion (Greece) were analyzed by Gas Chromatography-Mass Spectrometry. The major compounds found in EOs of A. grandifolia inflorescences from Mt. Menoikio were as follows: cis-thujone (36.9%), 1,8-cineole (11.9%), camphor (10.0%), ascaridole (7.3%), α-terpinene (6.4%), sabinene (4.1%), trans-thujone (3.6%), and cis-jasmone (3.4%). In leaves from Mt. Menoikio, they were as follows: cis-thujone (50.8%), 1,8-cineole (20.0%), trans-thujone (5.5%), camphor (5.5%), borneol (3.6%), and α-terpineol (3.1%). In inflorescences from Mt. Pelion, they were as follows: camphor (70.5%), camphene (5.9%), cis-jasmone (3.2%), bornyl acetate (3.2%). In leaves from Mt. Pelion, they were as follows: camphor (83.2%), camphene (3.9%), and borneol (3.7%). Subsequently, the samples were first time tested for their antioxidant activities with the interaction of EOs with DPPH (2,2-diphenyl-1-picrylhydrazyl) and their inhibition of lipid peroxidation, as well as for their anti-inflammatory activity through the soybean LOX (lipoxygenase) inhibition. All of the examined samples were found effective. A. grandifolia leaves presented the highest antioxidant potential according to the DPPH method, and the highest percentage of LOX inhibition. The study herein investigated for the first time the leaves and the inflorescences of A. grandifolia separately, and the results generally align with similar studies from neighboring countries (Turkey and Serbia) in terms of the yields and categorization of main EO compounds (oxygenated monoterpenes). However, the findings were not in agreement with previously studied Greek material, as a higher amount of cis-thujone and lower antioxidant activity are reported herein. Both the EOs of inflorescences and the leaves of the wild-growing population collected from Mt. Menoikio were characterized by a high quantity of cis-thujone (36.9% and 50.8%, respectively).

Abstract
The rapeseed (Brassica napus L.) are the important oil bearing material worldwide, which contain wide variety of bioactive components with polyphenolic compounds considered the most typical. The rapeseed polyphenols encompass different structural variants, and have been considered to have many bioactive functions, which are beneficial for the human health. Whereas, the rapeseed oil processing technologies affect their content and the biofunctional activities. The present review of the literature highlighted the major types of the rapeseed polyphenols, and summarized their biofunctional roles. The influences of rapeseed oil processing technologies on these polyphenols were also elucidated. Furthermore, the directions of the future studies for producing nutritional rapeseed oils preserved higher level of polyphenols were prospected. The rapeseed polyphenols are divided into the phenolic acids and polyphenolic tannins, both of which contained different subtypes. They are reported to have multiple biofunctional roles, thus showing outstanding health improvement effects. The rapeseed oil processing technologies have significant effects on both of the polyphenol content and activity. Some novel processing technologies, such as aqueous enzymatic extraction (AEE), subcritical or supercritical extraction showed advantages for producing rapeseed oil with higher level of polyphenols. The oil refining process involved heat or strong acid and alkali conditions affected their stability and activity, leading to the loss of polyphenols of the final products. Future efforts are encouraged to provide more clinic evidence for the practical applications of the rapeseed polyphenols, as well as optimizing the processing technologies for the green manufacturing of rapeseed oils.

Abstract
OBJECTIVES The aim of this study is to evaluate the anti-obesity, anti-hyperglycaemic, analgesic and antipyretic activities of Globularia alypum (GA). MATERIALS AND METHODS GA methanol and water extracts (GAME, GAWE) were administered to high-fat-high-glucose diet (HFFD) rats. RESULTS This study showed that GAME exhibited the highest antioxidant, anti-α-amylase and anti-lipase activities, with half inhibitory concentration (IC50) values 0.067, 1.05 and 2.97 mg/ml respectively. In HFFD rats, the administration of GAME inhibited lipase activity by 36, 37 and 30% in the intestine, pancreas and serum, respectively, reduced body weight by 17.7% and modulated lipid profile. In addition, administration of GAME to HFFD-rats decreased α-amylase activity, improved glucose level and protected liver function. Furthermore, the administration of GA extracts to rats revealed antipyretic (reduction in writhing by 64%) and analgesic (decrease of temperature by 1.11 °C) activities. CONCLUSION This study showed that GA extracts exhibited an anti-obesity, anti-hyperglycaemia, anti-pyretic and analgesic activities.

Abstract
Diabetes-related health issues are increasing day by day in public, and diabetic cardiomyopathy (DCM) is one serious issue among them. There is a lack of proper strategy to control and manage DCM. Here we are attempting a nutraceutical-based approach to protect the heart from DCM. The beneficial effect of cinnamic acid (CiA), was evaluated in an experimental model of diabetes. For this, diabetic model was created by feeding male Wistar rats with a high fat, high fructose diet for 6 months and a single dose of streptozotocin (25 mg/kg bwt). Metformin was used as the positive control. The diabetic rats showed insulin resistance, myocardial injury, and a significant increase of total cholesterol, triglycerides, and LDL. Development of DCM was evident from the increased cardiac mass index, LDH, CKMB, ANP, and CRP levels in the diabetic group. There was a significant increase in the levels of cardiac hypertrophy markers like TGF-β and β-MHC in the hearts of diabetic rats revealing DCM. Pro-inflammatory cytokines (TNF-α, IL-6) and lipid peroxides were significantly elevated in the serum of diabetic rats. Histopathology revealed inflammation and necrosis in the heart of diabetic rats confirming DCM. Oral administration of CiA (5 and 10 mg/kg bwt) prevented the development of DCM via its cardioprotective, anti-inflammatory, anti-dyslipidemia potential, and antidiabetic properties. Similarly, metformin (50 mg/kg bwt) has also shown protection against DCM. We conclude from this study that CiA is found to be beneficial against DCM and recommend more detailed preclinical and clinical studies to develop CiA-based nutraceutical against DCM.

Exploration of molecular mechanisms responsible for anti-inflammatory and anti-angiogenic attributes of methanolic extract of Viola betonicifolia. Inflammopharmacology 2022; 30:1459-1474. [PMID: 35608743 DOI: 10.1007/s10787-022-00990-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 04/02/2022] [Indexed: 11/05/2022]
Abstract
Uncontrolled inflammation plays a central role in the pathogenesis of various diseases. Currently available anti-inflammatory agents on prolonged use may lead to ulcers or thrombus formation. The present study was designed to evaluate the anti-inflammatory, anti-arthritic and anti-angiogenic potentials of methanol extract of Viola betonicifolia using battery of in vivo models. Methanol extract of Viola betonicifolia (Vb.Me) was prepared through maceration. High performance liquid chromatography (HPLC) and gas chromatography mass spectrometery (GC-MS) were performed to identify bioactive compounds present in Vb.Me. In vivo safety profile of Vb.Me was evaluated following OECD 425 acute toxicity guidelines. Anti-inflammatory potential of Vb.Me at three different dose levels was evaluated in in vivo acute (carrageenan and, histamine-induced paw oedema), sub-chronic (cotton pellet-induced granuloma) and chronic (Complete Freund's adjuvant-induced arthritis) models. Blood and paws samples were collected to study effects of Vb.Me treatment on the expression of various pro- and anti-inflammatory genes (RT-PCR) and to study the histopathological changes at tissue levels. Effects of Vb.Me on neovasculature development were studied in ex-ovo chicken chorioallantoic membrane (CAM) assay. Quercetin and n-hexadecanoic were identified as one of the major bioactive molecules in HPLC and GC-MS analysis of Vb.Me. Toxicity data revealed that Vb.Me was safe for administration up to the dose of 2000 mg/kg. Findings of inflammatory models showed that Vb.Me produced time and dose-dependent effects. 500 mg/kg Vb.Me showed significantly (p < 0.05) better effects as compared with 125 and 250 mg/kg. 500 mg/kg Vb.Me also showed comparable anti-inflammatory effects with indomethacin in both acute and chronic models respectively. RT-PCR data exhibited significant (p < 0.05) down-regulation of IL-6, IL-1ß, NF-kß, TNF-α and COX-2 genes with simultaneous up-regulation of IL-4 and IL-10 genes in the blood samples of animals treated with 500 mg/kg of Vb.Me and 10 mg/kg of indomethacin respectively. CAM assay data revealed arrest of microvessel outgrowth in Vb.Me-treated eggs. Altogether, findings of the current study indicate that Vb.Me exerts in vivo anti-inflammatory and anti-angiogenic effects through regulation of expression of various pro- and anti-inflammatory genes. Synergist actions of various bioactive molecules in Vb.Me are proposed to be responsible for these attributes. However, further studies to standardize the extract and evaluation of its potential in various inflammation-induced diseases are warranted.

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
Highly regio- and stereoselective palladium-catalyzed ortho-vinylation of β-naphthols (2) has been reported using easily accessible CF3-allyl carbonates (1). The regioselective nucleophilic γ-attack of the CF3-π-allyl-Pd-intermediate is the key to furnish (Z)-CF3-vinylnaphthols (3) in good yields. Furthermore, we achieved a one-pot synthesis of CF3-naphtho[2,1-b]furans (4) through an uninterrupted ortho-vinylation/oxidative radical cyclization reaction sequence.

Abstract
PURPOSE Drugs inhibiting the platelet P2Y12 receptor, such as clopidogrel and prasugrel, are potent antithrombotic agents and are widely used in cardiovascular disease. However, the adverse effects of these drugs have limited their clinical use. For example, clopidogrel resistance occurs in approximately one third of patients, while prasugrel increases the risk of major bleeding. Therefore, new generations of such drugs are of clinical interest. METHODS In this study, the pharmacodynamics of a new P2Y12 antagonist, CN-218, was compared with that of clopidogrel and prasugrel in rats and mice. The differences between CN-218 and clopidogrel include deuteration of the 7-position methyl carboxylate and the introduction of cinnamate in the 2-position of thiophene. RESULTS CN-218 had an antiaggregatory efficacy that was at least five times more potent than that of clopidogrel but not as potent as that of prasugrel. It had a significant impact on activated partial thromboplastin time (APTT), whereby the APTT of CN-218-treated rats was approximately 9 s longer than that of the vehicle- or clopidogrel-treated group, while it had no impact on prothrombin time (PT) in rats. CN-218 had a similar potent antithrombotic effect to that of prasugrel and clopidogrel and also reduced the risk of bleeding compared to prasugrel. CONCLUSION CN-218 may be a promising antithrombotic agent, with potent antiplatelet and significant anticoagulant activity, as well as a lower risk of bleeding compared to clopidogrel and prasugrel.

Abstract
Percutaneous absorption of drugs can be enhanced by ethosomes, which are nanocarriers with excellent deformability and drug-loading properties. However, the ethanol within ethosomes increases phospholipid membrane fluidity and permeability, leading to drug leakage during storage. Here, we developed and characterized a new phospholipid nanovesicles that is co-hybridized with hyaluronic acid (HA), ethanol and the encapsulated volatile oil medicines (eugenol and cinnamaldehyde [EUG/CAH]) for transdermal administration. In comparison with EUG/CAH-loaded ethosomes (ES), the formulation stability and percutaneous drug absorption of EUG/CAH-loaded HA-immobilized ethosomes (HA-ES) were significantly improved. After transdermal administration of HA-ES, the interstitial cells of Cajal in the colon of rats with trinitrobenzene sulfonate-induced ulcerative colitis (UC) were significantly increased, and the stem cell factor/c-kit signaling pathway was partly repaired. Overall, HA-ES possesses excellent deformability and showed improved efficacy against UC compared with ES, which is demonstrated as a promising transdermal delivery vehicle for volatile oil medicines.

Abstract
To design an anticancer drug capable of inhibiting not only the proliferation of the differentiated tumor cells but also reducing the tumorigenic capability of cancer stem cells (CSCs), the new PtIV prodrugs with axial cinnamate ligands were synthesized. We demonstrate their superior antiproliferative activity in monolayer and 3D spheroid antiproliferative activity tests using panel of cancer cell lines. An outstanding activity was found against rhabdomyosarcoma cells, one of the most problematic and poorly treatable pediatric tumors. The results also suggest that the released PtII compound inhibits antiproliferative activity of cancer cells by DNA-damage mediated mechanism; the released cinnamic acid can trigger processes leading to differentiation, making the CSCs more sensitive to killing by the platinum part of the complex. PtIV complex with axial cinnamate ligands is the first PtIV prodrug capable of overcoming CSCs resistance and induce death in both CSCs and bulk cancer.

Abstract
Rimulus cinnamon is the dried twig of Cinnamomum cassia Presl. It is widely used in China for the treatment of inflammatory processes, amenorrhea, and other diseases. We aimed to study the protective effects of ethyl acetate extracts of R. cinnamon (EAE) on systemic inflammation and lung injury in endotoxin-poisoned mice. EAE was administered 5 d prior to lipopolysaccharide (LPS) challenge with 15 mg/kg LPS. The administration of EAE increased the levels of interferon-γ (IFN-γ) and decreased the levels of interleukin-18 (IL-18) and tumor necrosis factor-α (TNF-α) in the serum. Additionally, EAE relieved the pathological changes in the tissues of the lungs and spleen, and significantly reduced the number of neutrophils in the lung tissues. In addition, treatment with EAE decreased the mRNA expression of the NLR family, pyrin domain-containing protein 3 (NLRP3), caspase-1, and interleukin-1β (IL-1β) in the lungs, as well as the expression of NLRP3, caspase-1 (p20), and pro-IL-1β proteins. These results demonstrated the promising anti-inflammatory effects of EAE in endotoxin-poisoned mice. Furthermore, EAE could alleviate the lung injury of endotoxin-poisoned mice by antagonizing the activation of the NLRP3 inflammasome.

Abstract
A series of sixteen ring-substituted N-arylcinnamamides was prepared and characterized. Primary in vitro screening of all the synthesized compounds was performed against Staphylococcus aureus, three methicillin-resistant S. aureus strains, Mycobacterium tuberculosis H37Ra, Fusarium avenaceum, and Bipolaris sorokiniana. Several of the tested compounds showed antistaphylococcal, antitubercular, and antifungal activities comparable with or higher than those of ampicillin, isoniazid, and benomyl. (2E)-N-[3,5-bis(trifluoromethyl)phenyl]-3-phenylprop-2-enamide and (2E)-3-phenyl-N-[3-(trifluoromethyl)phenyl]prop-2-enamide showed the highest activities (MICs = 22.27 and 27.47 µM, respectively) against all four staphylococcal strains and against M. tuberculosis. These compounds showed an activity against biofilm formation of S. aureus ATCC 29213 in concentrations close to MICs and an ability to increase the activity of clinically used antibiotics with different mechanisms of action (vancomycin, ciprofloxacin, and tetracycline). In time-kill studies, a decrease of CFU/mL of >99% after 8 h from the beginning of incubation was observed. (2E)-N-(3,5-Dichlorophenyl)- and (2E)-N-(3,4-dichlorophenyl)-3-phenylprop-2-enamide had a MIC = 27.38 µM against M. tuberculosis, while a significant decrease (22.65%) of mycobacterial cell metabolism determined by the MTT assay was observed for the 3,5-dichlorophenyl derivative. (2E)-N-(3-Fluorophenyl)- and (2E)-N-(3-methylphenyl)-3-phenylprop-2-enamide exhibited MICs = 16.58 and 33.71 µM, respectively, against B. sorokiniana. The screening of the cytotoxicity of the most effective antimicrobial compounds was performed using THP-1 cells, and these chosen compounds did not shown any significant lethal effect. The compounds were also evaluated for their activity related to the inhibition of photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts. (2E)-N-(3,5-dichlorophenyl)-3-phenylprop-2-enamide (IC50 = 5.1 µM) was the most active PET inhibitor. Compounds with fungicide potency did not show any in vivo toxicity against Nicotiana tabacum var. Samsun. The structure–activity relationships are discussed.

Abstract
Socheongryong-Tang (SCRT) is a natural medicine prescription that has been mainly used in East Asia for the treatment of inflammatory disorders, including asthma and allergic rhinitis. The present study evaluated the anti-inflammatory effects of SCRT on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and in a rat model of carrageenan (CA)-induced paw edema. Levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6 and prostaglandin E2 (PGE2) in the culture supernatant were quantified and nitric oxide (NO) production was monitored. In addition, the effect of SCRT on the protein expression of nuclear factor-κB (NF-κB), mitogen-activated protein kinases (MAPKs), inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) was assessed by western blot analysis. Furthermore, the effects of SCRT on acute inflammation in vivo and changes in the histomorphometry and histopathology of paw skin were observed using CA-treated rats. SCRT (1 mg/ml) inhibited the LPS-induced changes in the protein expression of NF-κB, JNK, ERK1/2, iNOS and COX-2, as well as the production of NO, PGE2 and cytokines. In the rat paw edema assay, administration of 1 g/kg of lyophilized powder obtained from the aqueous extracts of SCRT for 3 consecutive days inhibited the CA-induced increases in skin thickness, mast cell degranulation, and infiltration of inflammatory cells in the ventral and dorsal pedis skin within 4 h. These results demonstrated that SCRT exerts its anti-inflammatory activities in LPS-stimulated RAW 264.7 cells through decreasing the production of inflammatory mediators, including PGE2, NO and cytokines, via suppression of the NF-κB and JNK and ERK1/2 signaling pathways. In addition, the data of the CA-induced paw edema indicated an anti-edema effect of SCRT. SCRT (1 g/kg) reduced acute edematous inflammation through inhibition of mast cell degranulation and infiltration of inflammatory cells. Therefore, the present study provided scientific evidence for the anti-inflammatory activities of SCRT as well as the underlying mechanisms.

The Anti-Inflammatory Effects of Shinbaro3 Is Mediated by Downregulation of the TLR4 Signalling Pathway in LPS-Stimulated RAW 264.7 Macrophages. Mediators Inflamm 2018; 2018:4514329. [PMID: 29849490 PMCID: PMC5907526 DOI: 10.1155/2018/4514329] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2017] [Revised: 01/11/2018] [Accepted: 01/29/2018] [Indexed: 02/07/2023] Open
Abstract
Shinbaro3, a formulation derived from the hydrolysed roots of Harpagophytum procumbens var. sublobatum (Engl.) Stapf, has been clinically used in the pharamacopuncture treatment of arthritis in Korea. In the present study, Shinbaro3 inhibited NO generation in LPS-induced RAW 264.7 cells in a dose-dependent manner. Shinbaro3 also downregulated the mRNA and protein expression of inflammatory mediators in a dose-dependent manner. Three mechanisms explaining the effects of Shinbaro3 in RAW 264.7 cells were identified as follows: (1) inhibition of the extracellular signal-regulated kinase 1 and 2 (ERK1/2), stress-activated protein kinase (SAPK)/c-Jun N-terminal protein kinase (JNK), and p38 mitogen-activated protein kinase (MAPK) pathways; (2) suppression of IκB kinase-α/β (IKK-α/β) phosphorylation and nuclear factor-kappa B (NF-κB) subunits in the NF-κB pathway, which are involved in MyD88-dependent signalling; and (3) downregulation of IFN-β mRNA expression via inhibition of interferon regulatory factor 3 (IRF3) and Janus-activated kinase 1 (JAK1)/signal transducer and activator of transcription 1 (STAT1) phosphorylation, which is involved in TRIF-dependent signalling. Shinbaro3 exerted anti-inflammatory effects in LPS-stimulated RAW 264.7 macrophage cells through modulation of the TLR4/MyD88 pathways, suggesting that Shinbaro3 is a novel anti-inflammatory therapeutic candidate in the field of pharmacopuncture.

Abstract
Burns are known as one of the most common and destructive forms of injury with a vast spectrum of consequences. Despite the discovery of various antibacterial and antiseptic agents, burn wound healing still has remained a challenge to modern medicine. Plants have been considered as potential agents for prevention and treatment of disorders in recent years. Globularia alypum L. (GA) is widely used in folk medicine against skin diseases and abscesses, however there is no scientific evidence justifying its use. This study aimed to evaluate the wound healing and anti-inflammatory effect, the antibacterial and antioxidant activities, as well as the chemical compositions of GA methanolic extract (GAME). Chemical compounds of GAME were examined by GC-MS. Wound healing effect was assessed by second-degree burn wounds in rats, anti-inflammatory activity was studied by carrageenan-induced rat paw edema, antioxidant activity was estimated by the DPPH, reducing power and β-carotene tests and antimicrobial activity was tested against 6 bacteria. A total of 17 compounds were identified. GAME-treated rats showed an improvement in healing process and carrageenan-induced hind paws edema as assessed by histological and biochemical investigations, compared to the control. A significant antioxidant and antibacterial activities were also observed in GAME-treated rats. GAME revealed a burn wound healing activity probably due to the anti-inflammatory, antimicrobial and antioxidant activities of its phytochemical contents. Thus, this study confirms its traditional use, however further more precise studies are needed for future clinical application.

Abstract
Benefits to health from a high consumption of fruits and vegetables are well established and have been attributed to bioactive secondary metabolites present in edible plants. However, the effects of specific health-related phytochemicals within a complex food matrix are difficult to assess. In an attempt to address this problem, we have used elicitation to improve the nutraceutical content of seedlings of Brassica oleracea grown under controlled conditions. Analysis, by LC-MS, of the glucosinolate, isothiocyanate and phenolic compound content of juices obtained from sprouts indicated that elicitation induces an enrichment of several phenolics, particularly of the anthocyanin fraction. To test the biological activity of basal and enriched juices we took advantage of a recently developed in vitro model of inflamed human intestinal epithelium. Both sprouts' juices protected intestinal barrier integrity in Caco-2 cells exposed to tumor necrosis factor α under marginal zinc deprivation, with the enriched juice showing higher protection. Multivariate regression analysis indicated that the extent of rescue from stress-induced epithelial dysfunction correlated with the composition in bioactive molecules of the juices and, in particular, with a group of phenolic compounds, including several anthocyanins, quercetin-3-Glc, cryptochlorogenic, neochlorogenic and cinnamic acids.

Abstract
Context The underground edible tuber of Dioscorea alata L. (Dioscoreaceae) is a functional food with high nutritive value and therapeutic potential. The tuber is known to possess anti-inflammatory properties in traditional medicine. Objective The present study explores the anti-inflammatory activity and standardisation of D. alata tuber hydromethanol extract. Materials and methods Hydromethanol extract (70%) of D. alata tuber was chemically characterised using HPLC and GC-MS techniques. Murine lymphocytes were cultured for 48 h with six different concentrations (0-80 μg/mL) of the extract. The expression of nitric oxide (NO), TNF-α, COX-1, COX-2, and PGE2 were evaluated using colorimetric and ELISA methods. Results Dioscorea alata extract inhibited the expression of NO and TNF-α with an IC50 value of 134.51 ± 6.75 and 113.30 ± 7.44 μg/mL, respectively. The IC50 values for inhibition of total COX, COX-1, COX-2 activities and PGE2 level were 41.96 ± 3.07, 141.41 ± 8.99, 32.50 ± 1.69, and 186.34 ± 15.36 μg/mL, respectively. Inhibition of PGE2 level and COX-2 activity was positively correlated (R(2) = 0.9393). Gallic acid (GA), 4-hydroxy benzoic acid (4HBA), syringic acid (SYA), p-coumaric acid (PCA), and myricetin (MY) were identified and quantified using HPLC. GC-MS analysis revealed the presence of 13 different phytocompounds such as hexadecanoic acid, methyl stearate, cinnamyl cinnamate, and squalene. Conclusion The D. alata extract significantly down-regulated the pro-inflammatory signals in a gradual manner compared with control (0 μg/mL). Different bioactive phytocompounds individually possessing anti-inflammatory activities contributed to the overall bioactivity of the D. alata tuber extract.
