[PMID: 38986752 DOI: 10.1016/j.jep.2024.118543] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 06/28/2024] [Accepted: 07/08/2024] [Indexed: 07/12/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Abrus cantoniensis Hance (ACH), known as Jigucao (Chinese: ) has been used in ethnopharmacology for a long history with therapeutic effects for clearing heat, soothing the liver, especially in treating acute and chronic hepatitis which was very effective. In southern China, such as Guangdong and Guangxi, people often use ACH in soup or herbal tea as dietetic therapy. AIM OF THE REVIEW This paper aims to review ACH's ethnopharmacology, phytochemistry, and pharmacological activity systematically, at the same time, we also hope to provide more research avenues between traditional uses and pharmacological properties. MATERIAL AND METHODS Through PubMed, Wan Fang Database, CNKI, Web of Science, EBSCO Database, and Google Scholar search for relevant literature in both Chinese and English, the keywords "Abrus cantoniensis, Abrus cantoniensis Hance, Jigucao, pharmacology, chemical constituents, clinical application, network pharmacology" were used alone or combination. RESULTS Traditionally, ACH was believed to have the effect of soothing the liver, clearing heat, and detoxifying, often used to treat diseases of the liver and inflammation. Modern pharmacological research indicates that ACH has liver protection, anti-inflammation, anti-oxidant, immunomodulation, anti-tumor effects and so on. Whether it was a single chemical compound or an extract from ACH, studies have found that it has abundant pharmacological activities, these were the fundamental sources of traditional uses, like liver protection and anti-inflammation. CONCLUSIONS A systematic review found that modern phytochemistry and pharmacodynamic research reports on ACH are closely related to its traditional uses, especially its hepatoprotective and anti-inflammatory effects. Modern research has also further explored and expanded the effects of ACH, such as its anti-tumor effect. And all these efforts are gradually filling the gap between traditional uses and modern pharmacology. In general, the current research on the pharmacodynamic mechanism of ACH still needs further in-depth research, and the strategies adopted must also be further strengthened.

PHYTOCHEMISTRY 2024; 221:114064. [PMID: 38508326 DOI: 10.1016/j.phytochem.2024.114064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 03/06/2024] [Accepted: 03/14/2024] [Indexed: 03/22/2024]
Abstract
Abri Herba (AH, known as 'Ji-Gu-Cao' in China) has a long-term medicinal history of treating cholecystitis, acute and chronic hepatitis and non-alcoholic fatty liver (NAFL) in China or other Asian countries. This review aimed to provide a comprehensive analysis of AH in terms of ethnopharmacology, phytochemistry, pharmacology, pharmacokinetics and toxicology. The information involved in the study was collected from a variety of electronic resources, and >100 scientific studies have been used since 1962. Until now, 95 chemical compounds have been isolated and identified from AH and the seeds of Abrus cantoniensis Hance (ACH), including 47 terpenoids, 26 flavonoids and 4 alkaloids. The pharmacological activities of AH extracts and their pure compounds have been explored in the aspects of anti-hyperlipidaemia, hepatoprotection, anti-tumour, anti-viral, anti-bacterial, anti-inflammatory and analgesic, immunomodulation, antioxidant and others. The pharmacokinetics and excretion kinetics of AH in vivo and 15 traditional and clinical prescriptions containing AH have been sorted out, and the potential therapeutic mechanism and drug metabolism pattern were also summarised. The pods of ACH are toxic, with a median lethal dose (LD50) of 10.01 ± 2.90 g/kg (i.g.) in mice. Interestingly, the toxicity of ACH's pods and seeds decreased after boiling. However, the toxicity mechanism of pods of ACH is unclear, limiting its clinical application. Clinical trials in the future should be used to explore its safety. Meanwhile, as one of the relevant pharmacological activities, the effects and mechanism of AH on anti-hyperlipidaemia and hepatoprotection should be further studied, which is of great significance for understanding its mechanism of action in the treatment of NAFL disease and improving its clinical application.

Network pharmacology and experimental validation of effects of total saponins extracted from Abrus cantoniensis Hance on acetaminophen-induced liver injury. JOURNAL OF ETHNOPHARMACOLOGY 2024; 324:117740. [PMID: 38219885 DOI: 10.1016/j.jep.2024.117740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 01/06/2024] [Accepted: 01/07/2024] [Indexed: 01/16/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Abrus cantoniensis Hance (AC), an abrus cantoniensis herb, is a Chinese medicinal herb used for the treatment of hepatitis. Total saponins extracted from AC (ACS) are a compound of triterpenoid saponins, which have protective properties against both chemical and immunological liver injuries. Nevertheless, ACS has not been proven to have an influence on drug-induced liver injury (DILI). AIM OF THE STUDY This study used network pharmacology and experiments to investigate the effects of ACS on acetaminophen (APAP)-induced liver injury. MATERIALS AND METHODS The targets associated with ACS and DILI were obtained from online databases. Cytoscape software was utilized to construct a "compound-target" network. In addition, Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were used to analyze the related signaling pathways impacted by ACS. AutoDock Vina was utilized to evaluate the binding affinity between bioactive compounds and the key targets. To validate the findings of network pharmacology, in vitro and in vivo experiments were conducted. Cell viability assay, transaminase activity detection, immunofluorescence assay, immunohistochemistry staining, RT-qPCR, and western blotting were utilized to explore the effects of ACS. RESULTS 25 active compounds and 217 targets of ACS were screened, of which 94 common targets were considered as potential targets for ACS treating APAP-induced liver injury. GO and KEGG analyses showed that the effects of ACS exert their effects on liver injury through suppressing inflammatory response, oxidative stress, and apoptosis. Molecular docking results demonstrated that core active compounds of ACS were successfully docked to core targets such as CASP3, BCL2L1, MAPK8, MAPK14, PTGS2, and NOS2. In vitro experiments showed that ACS effectively attenuated APAP-induced damage through suppressing transaminase activity and attenuating apoptosis. Furthermore, in vivo studies demonstrated that ACS alleviated pathological changes in APAP-treated mice and attenuated inflammatory response. Additionally, ACS downregulated the expression of iNOS, COX2, and Caspase-3, and upregulated the expression of Bcl-2. ACS also suppressed the MAPK signaling pathway. CONCLUSIONS This study demonstrated that ACS is a hepatoprotective drug through the combination of network pharmacology and in vitro and in vivo experiments. The findings reveal that ACS effectively attenuate APAP-induced oxidative stress, apoptosis, and inflammation through inhibiting the MAPK signaling pathway. Consequently, this research offers novel evidence supporting the potential preventive efficacy of ACS.

FISH & SHELLFISH IMMUNOLOGY 2024; 144:109242. [PMID: 37995893 DOI: 10.1016/j.fsi.2023.109242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 09/13/2023] [Accepted: 11/17/2023] [Indexed: 11/25/2023]
Abstract
N-trans-p-coumaroyltyrosine (N-(E)-p-coumaroyltyrosine, NPCT), extracted and purified from Abri Mollis Herba, is an amino acid amide. The defense mechanism of NPCT against inflammatory response is still unknown. In this study, lipopolysaccharide (LPS)-induced zebrafish acute inflammatory injury model was established to observe the inhibitory effect of NPCT on the aggregation of inflammatory cells in the yolk sac of zebrafish, as well as the inhibitory effect of NPCT on inflammatory and gas signaling factors. Results show that NPCT could inhibit inflammatory cell infiltration in zebrafish yolk sac, the migration and aggregation of macrophages and neutrophils to the site of inflammation, and the release of Nitric Oxide (NO) and Reactive Oxygen Species (ROS) in zebrafish, indicating that NPCT could substantially significantly prevent the development of LPS-induced acute systemic inflammation. In addition, the analysis results of RNA-seq showed that in the model group versus the administered group, the differentially expressed genes were mainly enriched to inflammatory signaling pathways, such as the NOD-like receptor signaling pathway and Toll-like receptor signaling pathway, which were down-regulated in the administered group. The TLR4, MyD88, IRAK4, NF-κB, IκB, NLRP3, Caspase-1, ASC, IL-1β, and IL-6 genes were significantly different in the transcripts, and the overall trend of the qPCR results was consistent with the transcriptome sequencing results. Therefore, NPCT had a significant inhibitory effect on LPS-induced acute inflammatory injury in zebrafish, and its anti-inflammatory mechanism may be through the regulation of key genes on the NOD-like receptor signaling pathway and Toll-like receptor signaling pathway, thereby affecting the release of relevant inflammatory cytokines.

Abstract
A simple and sensitive liquid chromatography tandem mass spectrometry method was established and validated for the quantitative determination of abrine, hypaphorine, schaftoside and soyasaponin Bb in rat plasma. After preparation by protein precipitation with acetonitrile, the analytes and internal standard were separated on a Waters CORTECS T3 column using acetonitrile containing 0.1% formic acid and 0.1% formic acid in water as mobile phase by gradient elution in 2 min. The method showed excellent linearity over the range of 5-500 ng/ml with acceptable intra- and inter-day precision, accuracy, matrix effect and recovery. The stability assay indicated that the four analytes were stable during the analysis process. The method was applied to a pharmacokinetic study of Abrus cantoniensis Hance in rats. The result suggested that after oral administration, the four analytes were quickly absorbed into the plasma. The dose-normalized exposure of hypaphorine was the highest with a long elimination half-life (t1/2 9.83 h), followed by abrine and schaftoside with t1/2 values of 1.07 and 1.15 h. The dose normalized exposure of soyasaponin Bb was the lowest, which is possibily due to the high polarity and poor permeability. This study provides a basis for elucidating the material foundation of A. cantoniensis Hance.

Abstract
Litchi polysaccharides are a kind of macromolecular polymers with various biological activities and a wide range of molecular weights. In this study, two separate fractions, with average molecular weights of 378.67 kDa (67.33%) and 16.96 kDa (6.95%), which were referred to as LP1 and LP2, respectively, were separated using an ultrafiltration membrane. Their physicochemical properties, and immunomodulatory and prebiotic activity were compared. The results revealed that LP2 contained more neutral sugar, arabinose, galactose and rhamnose, but less uronic acid, protein, mannose and glucose than LP1. Compared with LP1, LP2 possessed higher solubility and lower apparent viscosity. LP2 exhibited stronger stimulation on macrophage secretion of NO, TNF-α and IL-6, as well as better proliferation of Lactobacillus plantarum, Leuconostoc mesenteroides, Lactobacillus casei and Bifidobacterium adolescentis. These results suggest that an ultrafiltration membrane might be used to prepare a highly-active polysaccharide fraction from litchi pulp that may be used for food or drug development.

Abstract
Abrus mollis Hance (Leguminosae) has a variety of biological activities, including anti-inflammatory, antioxidant, antibacterial, antiviral, and antitumor activities. However, the specific substances responsible for the anti-inflammatory effects are unknown. Abrusamide H (BJBS) is a truxillic acid derivative obtained from the leaves of Abrus mollis Hance and has potential anti-inflammatory effects. In this study, we aimed to estimate the potential effect and mechanism of BJBS in inflammation by establishing lipopolysaccharide (LPS)-stimulated RAW264.7 cells in vitro and an injured zebrafish tail fin in vivo. The RAW264.7 cells were treated with different concentrations of BJBS after LPS stimulation. The production of nitric oxide (NO) was detected by Griess reaction, and reactive oxygen species (ROS) were detected by an ROS assay kit. The levels of proinflammatory cytokines, including interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and interleukin 18 (IL-18) were measured by ELISA. Results showed that BJBS at all concentrations inhibited the proliferation of RAW264.7 macrophages after LPS stimulation by cell counting kit-8 and the production of NO and ROS. In the BJBS treatment group, the levels of IL-6, TNF-α, IL-1β, and IL-18 decreased in a concentration-dependent manner. The results in vivo showed that no significant difference in the survival of zebrafish between the BJBS and blank groups and BJBS inhibited the migration and aggregation of zebrafish neutrophils in a dose-dependent manner in inflammation induced by tail transection-induced inflammation. In conclusion, BJBS inhibited the production of NO and ROS, decreased the levels of secreted IL-6, TNF-α, IL-1β, and IL-18, and reduced the migration and aggregation of zebrafish neutrophils.

Abstract
The study aims to elucidate the physicochemical properties and immunomodulatory activity of two polysaccharides (ACPt0 and ACPt2) from Abrus cantoniensis. Results revealed that ACPt0 with a molecular weight of 26.0 kDa, was mainly composed of glucose (83.1%) and galactose (6.1%), and that ACPt2 with a molecular weight of 145.6/8.9 kDa, consisted of galactose (25.6%), galacturonic acid (22.2%), arabinos (16.6%) and galactose (11.0%) respectively. AFM and Congo red experiments suggested that ACPt0 and ACPt2 might be spherical particles with triple-helix conformation in aqueous solution. ACPt0 and ACPt2 exhibited immunomodulatory activity by promoting the proliferation, augmenting pinocytic and phagocytic capacities, releasing immunoactive molecules such as ROS, NO, iNOS, TNF-α, IL-6 and IL-1β, upregulation of the mRNA levels of corresponding cytokines in macrophages. Moreover, ACPt0 and ACPt2 were recognized by toll-like receptor 4 (TLR4) and exerted immunomodulatory effects via activating Myeloid differentiation factor 88 (MyD88), mitogen-activated protein kinases (MAPKs) and serine/threonine kinase (Akt) signaling pathways in macrophages. Notably, ACPt2 had higher immunomodulatory activity than ACPt0. Based on the present findings, ACPt0 and ACPt2 could be explored as an active component of immunomodulators in the food and pharmaceutical fields.

Polysaccharides From Abrus cantoniensis Hance Modulate Intestinal Microflora and Improve Intestinal Mucosal Barrier and Liver Oxidative Damage Induced by Heat Stress. Front Vet Sci 2022; 9:868433. [PMID: 35445100 PMCID: PMC9013755 DOI: 10.3389/fvets.2022.868433] [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: 02/02/2022] [Accepted: 03/02/2022] [Indexed: 11/13/2022] Open
Abstract
The protective effects of polysaccharides from Abrus cantoniensis Hance (ACP) on antioxidant capacity, immune function, the hypothalamus-pituitary-adrenal (HPA) axis balance, the intestinal mucosal barrier, and intestinal microflora in heat stress (HS)-induced heat-injured chickens are rarely reported. The purpose of this study was to investigate the protective effects of ACP on HS-injured chickens by enhancing antioxidant capacity and immune function, repairing the intestinal mucosal barrier, and regulating intestinal microflora. A total of 120 native roosters in Guangxi were randomly divided into 5 groups to evaluate the protective effect of ACP on chickens injured by HS (33 ± 2°C). The results showed that ACP increased the body weight and the immune organ index of heat-injured chickens, regulated the oxidative stress kinase secretion, and restored the antioxidant level of heat-injured birds. ACP significantly inhibited the secretion of corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and corticosterone (COR) and reversed the disorder of hormone levels caused by HS. ACP significantly regulated the secretion levels of immune cytokines and restored the immune function of the body. ACP significantly improved the intestinal morphology and increased the expression levels of tight junction proteins, which had a positive effect on protecting intestinal health. The results of high-throughput sequencing of the 16S rRNA gene showed that HS led to an increase in the abundance of harmful bacteria and an abnormal increase in the abundance of intestinal microflora and that ACP restored the HS-induced intestinal microflora imbalance. In conclusion, this study provides a scientific basis for ACP as an antioxidant activity enhancer to reduce liver injury, regulate intestinal microflora, and protect intestinal mucosal damage in chickens.

Int J Biol Macromol 2021; 192:967-977. [PMID: 34655586 DOI: 10.1016/j.ijbiomac.2021.10.049] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 10/07/2021] [Accepted: 10/07/2021] [Indexed: 01/13/2023]
Abstract
Lactarius volemus Fr. is an edible mushroom widely consumed in China. Polysaccharide is an important nutritional component of L. volemus. This research aimed to isolate the polysaccharide from L. volemus and study its structure and bioactivities. A purified polysaccharide was identified and named as LVF-I whose primary structure was proposed considering the comprehensive results of monosaccharide composition, periodate oxidation-smith degradation, methylation analysis, FT-IR and 1D/2D NMR spectroscopy. Then the immunomodulation of LVF-I and its inhibition effect on H1299 and MCF-7 cells were investigated. Results showed that LVF-I (12,894 Da) contained fucose, mannose, glucose and galactose. It had a backbone consisting of →4)-α-D-Glcp-(1→, →6)-β-D-Manp-(1→, →6)-α-D-Galp-(1 → and →4)-β-D-Manp-(1→. And its side chains were branched at C2 of →4)-β-D-Manp-(1 → by →6)-α-D-Galp-(1→, α-D-Glcp-(1→, α-D-Galp-(1 → and α-L-Fucp-(1→. LVF-I (250-1000 μg/mL) could inhibit the proliferation of H1299 and MCF-7 cells, while enhance the proliferative response of splenocyte and the phagocytic ability of RAW264.7. Furthermore, LVF-I (250-1000 μg/mL) significantly induced the secretion of nitric oxide, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) by up-regulating their mRNA expression in macrophages. These results suggested that LVF-I had the potential to be developed as antitumor or immunomodulatory agents by inhibiting the proliferation of tumor cells and stimulating macrophages-mediated immune responses.

Abstract
Natural polysaccharide is a kind of natural macromolecular which can be extracted from
plants, fungi, algae, animals, and bacteria. The monosaccharide compositions and glucosidic bonds of
polysaccharides from different origins vary substantially. Natural polysaccharides have been shown to
possess complex, important and multifaceted biological activities including antitumor, anticoagulant,
antioxidative, antiviral, immunomodulatory, antihyperlipidemic and antihepatotoxic activities. Their
properties are mainly due to their structural characteristics. It is necessary to develop polysaccharide
immunomodulators with potential for preventive or therapeutic action. The present paper summarizes
the structural features, immunostimulatory activity and the immunomodulatory mechanisms of natural
polysaccharides. In particular, it also provides an overview of representative natural polysaccharide
immunomodulators.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 249:112366. [PMID: 31678415 DOI: 10.1016/j.jep.2019.112366] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 10/19/2019] [Accepted: 10/27/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hepatitis B, an infectious disease caused by hepatitis B virus (HBV), is still a serious problem affecting global public health. Abrus cantoniensis Hance (AC), a traditional Chinese medicinal herb, has been used as a folk medicine for treating hepatitis in China from ancient times. However, its active ingredients are still unclear. AIM OF STUDY Our previous study indicated that saponins extracted from AC (ACS) were the active anti-HBV ingredients in AC. This study aimed to further investigate the anti-HBV effect of ACS in vitro and in vivo. MATERIALS AND METHODS HepG2.2.15 cells which consecutively produce HBV DNA and HBV antigens were used for in vitro test, and C57BL/6 mice infected by a recombinant adeno-associated virus 8 vector carrying 1.3 copies of HBV genome (rAAV8-HBV1.3) were used for in vivo test. The histopathological changes and the immune indices were evaluated in mice model. Genechip was conducted to identify genes and pathways regulated by ACS in HepG2.2.15 cells. RESULTS In this study, we confirmed that ACS treatment prominently inhibited production of HBV DNA, Hepatitis Be Antigen (HBeAg), and Hepatitis B surface antigen (HBsAg) in HepG2.2.15 cells. ACS treatment also decreased serum HBsAg, HBeAg, and HBV DNA level in rAAV8-1.3HBV transfected mice, which is in accordance with the in vitro results. Moreover, HBV infection-induced liver inflammation was significantly relieved by ACS, which could be observed in H&E staining and immunohistochemistry of HBcAg. ACS treatment elevated IFN-γ level in mice serum and increased CD4+ T cell percentage in splenocytes. KEGG pathway analysis showed that phenylalanine metabolism pathway and tyrosine metabolism pathway were greatly regulated by ACS treatment. CONCLUSION ACS exerted potent inhibitory effects on HBV replication both in vivo and in vitro, which may provide basis for its potential clinical usage.

Abstract
A polysaccharide fraction from Solanum nigrum, SN-ppF3 was shown previously to have an immunomodulatory activity where it could possibly be used to enhance the host immune response in fighting cancer. The non-toxic SN-ppF3 was fed orally to breast tumor bearing-mice with concentrations of 250 and 500mg/kg for 10days. During the treatment period, size of the tumor and weight of the mice were monitored. At the end of the treatment, blood, tumor, spleen and thymus were harvested for physiological and immunological analyses. After the treatment, the tumor volume and tumor weight were significantly inhibited by 65% and 40%, respectively. Based on the histological observation, the treatment of SN-ppF3 resulted in the disruption of tumor cells morphology. The increase in infiltrating T cells, NK cells and macrophages were observed in tumor tissues of the treated mice, which partly explained the higher apoptosis tumor cells observed in the treated mice. Moreover, the level of TNF-α, IFN-γ and IL-4 were elevated, while the level of IL-6 was decreased significantly, in serum of the treated mice. These results suggested that tumor suppression mechanisms observed in SN-ppF3-treated mice were most probably due through enhancing the host immune response.
