Abstract
Porcine epidemic diarrhea virus (PEDV) is a member of the genera Alphacoronavirus that has been associated with acute watery diarrhea and vomiting in swine. Unfortunately, no effective vaccines and antiviral drugs for PEDV are currently available. Reverse genetics systems are crucial tools for these researches. Here, a PEDV full-length cDNA clone was constructed. Furtherly, three PEDV reporter virus plasmids containing red fluorescent protein (RFP), Nano luciferase (Nluc), or green fluorescence protein (GFP) were generated using Red recombination with the GS1783 E. coli strain. These reporter-expressing recombinant (r) PEDVs showed similar growth properties to the rPEDV, and the foreign genes were stable to culture up to P9 in Vero cells. Using the Nluc-expressing rPEDV, the replication of PEDV was easily quantified, and a platform for rapid anti-PEDV drug screening was constructed. Among the three drugs, Bergenin, Umifenovir hydrochloride (Arbidol), and Ganoderma lucidum triterpenoids (GLTs), we found that GLTs inhibited PEDV replication mainly after the stage of virus "Entry". Overall, this study will broaden insight into the method for manipulating the PEDV genome and provide a powerful tool for screening anti-PEDV agents.

Lipids Health Dis 2023; 22:203. [PMID: 38001454 PMCID: PMC10668478 DOI: 10.1186/s12944-023-01973-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 11/14/2023] [Indexed: 11/26/2023] Open
Abstract
OBJECTIVE The goal of this study was to explore the hypolipidemic effects of bergenin extracted from Saxifraga melanocentra Franch (S. melanocentra), which is a frequently utilized Tibetan medicinal plant known for its diverse bioactivities. Establishing a quality control system for black stem saxifrage is crucial to ensure the rational utilization of its medicinal resources. METHODS A one-step polyamide medium-pressure liquid chromatography technique was applied to isolate and prepare bergenin from a methanol extract of S. melanocentra. A zebrafish model of hyperlipidemia was used to investigate the potential hypolipidemic effects of bergenin. RESULTS The results revealed that bergenin exhibited substantial hypo efficacy in vivo. Specifically, bergenin significantly reduced the levels of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-c) while simultaneously increasing high-density lipoprotein cholesterol (HDL-c) levels. At the molecular level, bergenin exerted its effects by inhibiting the expression of FASN, SREBF1, HMGCRα, RORα, LDLRα, IL-1β, and TNF while promoting the expression of IL-4 at the transcriptional level. Molecular docking analysis further demonstrated the strong binding affinity of bergenin to proteins such as FASN, SREBF1, HMGCRα, RORα, LDLRα, IL-4, IL-1β, and TNF. CONCLUSIONS Findings indicate that bergenin modulates lipid metabolism by regulating lipid and cholesterol synthesis as well as inflammatory responses through signaling pathways associated with FASN, SREBF1, and RORα. These results position bergenin as a potential candidate for the treatment of hyperlipidemia.

Abstract
Bergenin is a glycosidic derivative of trihydroxybenzoic acid that was discovered in 1880 by Garreau and Machelart from the rhizomes of the medicinal plant Bergenia crassifolia (currently: Saxifraga crassifolia—Saxifragaceae), though was later isolated from several other plant sources. Since its first report, it has aroused interest because it has several pharmacological activities, mainly antioxidant and anti-inflammatory. In addition to this, bergenin has shown potential antimalarial, antileishmanial, trypanocidal, antiviral, antibacterial, antifungal, antinociceptive, antiarthritic, antiulcerogenic, antidiabetic/antiobesity, antiarrhythmic, anticancer, hepatoprotective, neuroprotective and cardioprotective activities. Thus, this review aimed to describe the sources of isolation of bergenin and its in vitro and in vivo biological and pharmacological activities. Bergenin is distributed in many plant species (at least 112 species belonging to 34 families). Both its derivatives (natural and semisynthetic) and extracts with phytochemical proof of its highest concentration are well studied, and none of the studies showed cytotoxicity for healthy cells.

Abstract
OBJECTIVES Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by inflammation, pain, and cartilage and bone damage. There is currently no cure for RA. It is however managed using nonsteroidal anti-inflammatory drugs, corticosteroids and disease-modifying anti-rheumatic drugs, often with severe side effects. Hidden within Africa's lush vegetation are plants with diverse medicinal properties including anti-RA potentials. This paper reviews the scientific literature for medicinal plants, growing in Africa, with reported anti-RA activities and identifies the most abundant phytochemicals deserving research attention. A search of relevant published scientific literature, using the major search engines, such as Pubmed/Medline, Scopus, Google Scholar, etc. was conducted to identify medicinal plants, growing in Africa, with anti-RA potentials. KEY FINDINGS Twenty plants belonging to 17 families were identified. The plants are rich in phytochemicals, predominantly quercetin, rutin, catechin, kaempferol, etc., known to affect some pathways relevant in RA initiation and progression, and therefore useful in its management. SUMMARY Targeted research is needed to unlock the potentials of medicinal plants by developing easy-to-use technologies for preparing medicines from them. Research attention should focus on how best to exploit the major phytochemicals identified in this review for the development of anti-RA 'green pharmaceuticals'.

Anti-inflammatory natural products as potential therapeutic agents of rheumatoid arthritis: A systematic review. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 93:153766. [PMID: 34624807 DOI: 10.1016/j.phymed.2021.153766] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 08/23/2021] [Accepted: 09/16/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease causing severe locomotor disability and deterioration in the quality of life. Existing treatments for RA mainly focus on the use of immunomodulators and the suppression of synovial inflammation, and many have significant side effects. Medicinal plants are regarded as important alternative sources for treating RA. PURPOSE This review summarizes the bioactive compounds of medicinal plants, which have been shown to modulate the immune response by regulating interleukins in vitro and in vivo experimental models, and that may be promising substances for use in the treatment of RA. METHODS Articles on natural products used for the management of arthritis were retrieved from PubMed, Embase, Scopus, and Web of Science through electronic and manual search in English. In total, 576 publications were identified, and 34 were included in this systematic review. RESULTS Two articles presented findings on the role of natural components in the treatment of arthritis in both in vitro and in vivo studies. Nine reports defined the role of plant-derived natural molecules in the treatment of arthritis using cell lines, and 27 in vivo studies assessed the anti-arthritic efficacy and immunomodulation effects of phytoconstituents on interleukin production and inflammatory responses. CONCLUSION This systematic review broadly reports that, in contrast to other classes of phytochemicals, flavonoids have the greatest therapeutic potential against arthritis by modulating the expression of pro-inflammatory TNF-α, IL-1β, IL-6, IL-8, and IL-17, as well as anti-inflammatory IL-2 and IL-10 cytokines, through the suppression of dynamic inflammatory biomarkers.

Abstract
Our study has renewed interest in the genus Jasmine for the treatment of chronic inflammatory conditions. Aerial parts of Jasminum grandiflorum L. subsp. floribundum total methanolic extract (JTME) were tested for its therapeutic potential as an anti-inflammatory agent using two experimental models in rats; acetic acid (AA) induced ulcerative colitis and adjuvant induced arthritis. The administration of JTME showed anti-inflammatory activity in a dose dependent manner. JTME, 400 mg/kg was like prednisolone, 2 mg/kg p.o. (the reference drug), since it improved the tissues of the colon clinically, macro and microscopically (ulcer index), and histopathological (scoring). It reduced the intestinal expression of pro-inflammatory cytokines in the colonic mucosa; IFNγ, TNFα, IL-6, IL-1, and MPO. It also preserved tight junctions in intestinal epithelial cells by counter-regulating claudin-5 and occludin levels additionally, it had a potent antioxidant activity. The expressions of NF-κB p65, TNF-α and caspase-3 in rats administered AA (2 mL of 4% solution, once, intrarectally) were significantly increased, where the lowest expression was scored in JTME, 400 mg/kg group. In the adjuvant induced model of rheumatoid arthritis, the TJME, 400 mg/kg reduced the levels of cathepsin D, iNOS, NO, RF, CRP, CPP and elevated the total antioxidant capacity of tissues. Additionally, it maintained bones without histopathological lesions, articular cartilage damage, and inflammation of the synovial membrane and periarticular tissues, in contrast to arthritic rats. Finally, we report a new detailed study to validate the medicinal importance of Jasminum for the chronic inflammatory disorders with immune dysfunction with anti-inflammatory and antioxidant effects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Caralluma species are traditional edible herbs used in folkloric medicine as antidiabetic, antioxidant, antipyretic, antirheumatic, anti-inflammatory and anthelmintic agents. C. quadrangula was selected in this study to document the traditional use of the genus as anti-rheumatic treatment and the possible mechanisms of action. AIM OF THE STUDY The higher mortality rates and shorter survival among the patients suffering from rheumatoid arthritis (RA) led to the increased interest on searching for new treatments for RA. Russelioside B (RB), a major pregnane glycoside found in C. quadrangula, was evaluated as a new anti-rheumatic agent. MATERIALS AND METHODS The n-butanol fraction of C. quadrangula was chromatographed on a silica gel column to isolate RB. The adjuvant-induced arthritis (AIA) model was established in rats by intradermal injection of complete Freund's adjuvant (CFA) to evaluate its anti-arthritic effect. Ibuprofen was used as a reference drug. Forty rats were randomly divided into 5 groups (n = 8): normal (NOR); CFA model (CFA); ibuprofen, 5 mg/kg; RB, 25 mg/kg and RB, 50 mg/kg. The treatments were initiated from day 16 when AIA model was established and continued up to day 40. Serum diagnostic rheumatoid markers, inflammatory cytokines, oxidative stress biomarkers, cartilage and bone degeneration enzymes were assessed. RESULTS RB at 50 mg/kg b. wt., showed significant decreases in the activities of hyaluronidase and β-glucouronidase enzymes as well significant decreases in the levels of proinflammatory cytokines as nuclear factor-kappa-B (NF-κB), tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) compared to the CFA group; 11.04 ± 0.61 pg/mg protein, 4.35 ± 0.25 pg/mg protein, 3.32 ± 0.13 pg/mg protein & 2.75 ± 0.14 pg/mg protein for RB, 50 mg/kg b. wt. group vs. 25.33 ± 2.13 pg/mg protein, 25.65 ± 2.1 pg/mg protein, 22.20 ± 1.34 pg/mg protein & 13.27 ± 1.40 pg/mg protein for the arthritic group, respectively. The total antioxidant capacity (TAC) was significantly restored to normal values in RB, 50 mg/kg treated rats (4.01 ± 0.09 nmol/mL vs. 3.71 ± 0.27 nmol/mL) and the levels of myeloperoxidase (MPO) reduced by 10-folds of the CFA arthritic group. Bone histomorphometry revealed that RB treatment significantly attenuated the CFA-induced bone loss in a dose-dependent manner. CONCLUSIONS These findings suggested that the anti-arthritic effect of RB was mediated through the reduction of the rheumatoid markers, anti-inflammatory and antioxidant action, inhibition of cartilage and bone degenerative enzymes as well as attenuation of bone loss and osteoclastogenesis.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 247:112201. [PMID: 31499140 DOI: 10.1016/j.jep.2019.112201] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/30/2019] [Revised: 08/26/2019] [Accepted: 08/27/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bergenin is a well-known active compound that exhibits antioxidant, antiarrhythmic, hepatoprotective, and anti-inflammatory activities. However, the resource reserve of Rodgersia sambucifolia, one of the main raw materials for extracting bergenin, have sharply declined, and the bergenin content in different germplasms differs vastly, resulting in a serious shortage of the market supply of bergenin. AIM OF THE STUDY To investigate the influence of genetic diversity and environmental factors on bergenin content in Rodgersia sambucifolia. MATERIALS AND METHODS Fifty Rodgersia sambucifolia samples with a growth period of 2-3 years were collected from different areas across China and the bergenin content was determined via HPLC. Meanwhile the total genomic DNA was extracted and ISSR was performed. The bergenin content as measured using HPLC and the environmental data gathered from the meteorological stations and field work were combined and analyzed using correlation tests in XLSTAT 2018 to detect the key factors affecting bergenin content. The genetic UPGMA tree constructed based on genetic distances of the 50 samples and the chemical dendrogram constructed according to the distance between the bergenin content were compared to determine the correlation between genetic and chemical differentiation. RESULTS Among the 50 individuals, bergenin content varied from 2.83 to 12.54%, with the highest content being 4.43-fold that of the lowest content. The survey of the 50 individuals produced a total of 193 amplified bands, 187 of which were polymorphic (96.89%). In the study, bergenin content was positively correlated with annual mean temperature (AMT) (r = 0.583, P < 0.0001) and 1-12 month monthly mean temperature (MMT) (P < 0.0001). A comparison of the genetic dendrogram with the AHC dendrogram found no corresponding relationship between them. Mantel correlation analyses also showed that there was no significant correlation between them (r = 0.144). CONCLUSIONS There were large differences in bergenin content among different germplasms that were not correlated with the high genetic variation in Rodgersia sambucifolia but were significantly correlated with environmental factors, such as temperature. This study lays the foundation for subsequent superior germplasm selection and artificial breeding of Rodgersia sambucifolia to improve the bergenin content and meet market demands.

Eur J Pharmacol 2019; 858:172480. [PMID: 31228453 DOI: 10.1016/j.ejphar.2019.172480] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Revised: 06/18/2019] [Accepted: 06/18/2019] [Indexed: 11/18/2022]
Abstract
Bone formation refers to a series of complex events related to the activities of osteoblasts. In this study, we evaluated the osteogenesis activity of a natural compound named isocoumarin A that was isolated from the rhizomes of Polygonum amplexicaule on the non-transformed preosteoblastic cell line MC3T3-E1 for an in vitro study, and the results revealed that it increased the proliferation and promoted the mineralization of the extracellular matrix of MC3T3-E1 cells after treatment for 3 d in a dose-dependent manner. The cell metabolic activity peaked at 169% at 10 μM, and the activity of alkaline phosphatase (ALP) tripled to 15.94 U/mg compared with the control group. The protein levels of morphogenetic protein 2 (BMP-2), runt-related transcription factor 2 (RUNX2), ALP, and the mRNA levels of ALP, type I collagen (COL-1), and osteocalcin (OCN) were also upregulated after isocoumarin A administration. The mechanism investigation revealed that these effects were associated with the activation of the p-Akt/p-Erk1/2-activated BMP/RUNX2 signaling pathway. Subsequently, the in vivo investigation on the zebrafish embryos model demonstrated that isocoumarin A (0.30 mM) increased the number of vertebrae (5.38 ± 2.07 pcs) and the vertebral area (433.25 ± 111.77 μm2) in the development process of zebrafish embryos after a 7-day postfertilization (dpf) culture compared with the control group (2.50 ± 1.16 pcs and 209.75 ± 86.40 μm2). Together, these results indicated that isocoumarin A could be viewed as a promising candidate in early drug discovery and development to promote the healing of fractures and postmenopausal osteoporosis.

Lopes de Oliveira GA, Alarcón de la Lastra C, Rosillo MÁ, Castejon Martinez ML, Sánchez-Hidalgo M, Rolim Medeiros JV, Villegas I. Preventive effect of bergenin against the development of TNBS-induced acute colitis in rats is associated with inflammatory mediators inhibition and NLRP3/ASC inflammasome signaling pathways. Chem Biol Interact 2018; 297:25-33. [PMID: 30365937 DOI: 10.1016/j.cbi.2018.10.020] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Revised: 10/01/2018] [Accepted: 10/22/2018] [Indexed: 01/09/2023]
Abstract
Ulcerative colitis is an idiopathic inflammatory bowel disease characterized by intestinal inflammation; blocking this inflammatory process may be the key to the development of new naturally occurring anti-inflammatory drugs, with greater efficiency and lower side effects. The objective of this study is to explore the effects of bergenin (BG) in TNBS (2,4,6-trinitrobenzenesulfonic acid)-induced acute colitis model in rats in order to assist in the studies for the development of novel natural product therapies for inflammatory bowel disease. 48 Wistar rats were randomized into six groups: (i) Control and (ii) TNBS control; (iii) 5-ASA 100 mg/kg/day (iv) BG 12 mg/kg/day (v) BG 25 mg/kg/day and (vi) BG 50 mg/kg/day. Colitis was induced by instillation of TNBS. Colitis was evaluated by an independent observer who was blinded to the treatment. Our results revealed that bergenin decreased the macroscopic and microscopic damage signs of colitis, and reduced the degree of neutrophilic infiltration in the colon tissue; also, it was capable to down-regulate COX-2, iNOS, IkB-α, and pSTAT3 protein expression. Similarly, using a protocol for indirect ELISA quantification of cytokines, bergenin treatment reduced IL-1β, IFN-γ and IL-10 levels, and inhibited both canonical (IL-1) and non-canonical (IL-11) NLRP3/ASC inflammasome signaling pathways in TNBS-induced acute colitis. Conclusion: Our study has provided evidence that administration of bergenin reduced the damage caused by TNBS in an experimental model of acute colitis in rats, reduced levels of pro-inflammatory proteins and cytokines probably by modulation of pSTAT3 and NF-κB signaling and blocking canonical and non-canonical NLRP3/ASC inflammasome pathways.
