JOURNAL OF ETHNOPHARMACOLOGY 2024; 333:118417. [PMID: 38830452 DOI: 10.1016/j.jep.2024.118417] [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: 04/30/2024] [Revised: 05/27/2024] [Accepted: 06/01/2024] [Indexed: 06/05/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Saposhnikoviae Radix (SR) was initially documented in Shennong Bencao Jing classics for its properties in dispelling wind, dissolving surface, relieving pain, and alleviating spasms. This herb is commonly used in traditional Chinese medicine to address conditions that affect the body's surface, by aiding in the expulsion of pathogens from the surface and alleviating pain associated with the immune response. Atopic dermatitis (AD) is a prevalent allergic skin disorder, and the therapeutic effects of SR in dispelling wind and relieving the body's surface are consistent with the clinical symptoms commonly observed in AD. AIM OF THE STUDY The anti-AD effects of SR were examined under three different growth patterns to identify active pharmacodynamic compounds. The results provide insight into the clinical efficacy of wild and cultivated SR. MATERIALS AND METHODS The efficacy of wild, wild-simulated, and cultivated SR was assessed in a mouse model of AD. In addition, the effects of wild and varying doses of cultivated SR were evaluated in mice with short-term AD symptoms. GC-MS and UPLC-MS/MS were used to analyze the chemical components of the three SR treatments and molecular docking was used to identify active components. RESULTS A mouse model of AD was used to assess the pharmacodynamic effects of SR prepared by three different cultivation methods. The study found that all three SR preparations improved phenotypic markers and histopathological features in the AD mouse model. The efficacy of wild SR and wild-simulated SR was similar, although there was a significant difference between wild and cultivated SR. Both wild SR and various doses of cultivated SR ameliorated skin injuries and reduced inflammation in serum and skin tissues. Furthermore, skin thickness, inflammatory cells, mast cell infiltration, and IL-33 expression improved following treatment. Notably, wild SR, double-cultivated SR, and triple-cultivated SR demonstrated significant therapeutic effects. An analysis using GC-MS revealed the presence of 55, 52, and 43 volatile oils in the three SR preparations, with more common components observed between wild and wild-simulated SR. Fewer common components were evident between cultivated and wild SR. UPLC-MS/MS analysis identified a total of 37 compounds, with larger relative peak areas observed for the chromogenic ketones. Molecular docking studies revealed that certain compounds, such as n-propyl 9,12-octadecadienoate, (E)-9-octadecenoic acid ethyl ester, and various chromogenic ketones, such as cimifugin, 5-O-methyIvisamminol, hamaudol, 3'-O-acetylhamaudol, 3'-O-angeloyhamandol, adenosine and farnesylaceton, may be the major substances that distinguish the activities of SR with three different growth patterns. CONCLUSION Variations in the anti-AD efficacy of SR with three growth patterns were identified, and their chemical composition differences were determined. These findings suggest that increasing the dosage of cultivated SR could potentially be a viable clinical alternative for atopic dermatitis treatment.

Carbohydr Polym 2024; 342:122417. [PMID: 39048243 DOI: 10.1016/j.carbpol.2024.122417] [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: 02/21/2024] [Revised: 06/16/2024] [Accepted: 06/17/2024] [Indexed: 07/27/2024]
Abstract
RSA-1 is a polysaccharide obtained from Raphani semen with a relatively clear structure and anti-colon cancer activity. In this study, high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and nuclear magnetic resonance (NMR) spectroscopy were applied to characterise the complex chain structure of RSA-1. Subsequently, the inhibitory effect on colon cancer growth through apoptosis induction in colon cancer cells was explored. The findings indicate that the main chain of RSA-1 consists of →3)-β-D-Galp-(1 → and 3,6)-β-D-Galp-(1 → substituted at C-6 with branched α-L-Araf side chains. RSA-1 disrupts the Bax/Bcl-2 ratio and thus inhibits the viability of colon cancer cells in vitro. Furthermore, it inhibits colon cancer migration by attenuating epithelial-mesenchymal transition. Notably, RSA-1 exhibited negligible impact on the growth of human intestinal epithelial cells within a relevant concentration range. This study establishes a theoretical foundation and provides technical support for the prospective development and application of RSA-1 as a dual-purpose anti-colon cancer drug and functional food.

[PMID: 38858019 DOI: 10.1016/j.carbpol.2024.122259] [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: 01/21/2024] [Revised: 05/08/2024] [Accepted: 05/10/2024] [Indexed: 06/12/2024]
Abstract
Our previous investigations have successfully identified the repeating structural units of EPS53, an exopolysaccharide derived from Streptococcus thermophilus XJ53 fermented milk, and substantiated its potential immunomodulatory properties. The present study further elucidated the structural characteristics of EPS53 and investigated the underlying mechanisms governing its in vitro immunoreactivity as well as its in vivo immunoreactivity. The results obtained from multi-detector high performance gel filtration chromatography revealed that EPS53 adopted a rigid rod conformation in aqueous solution, with the weight-average molecular weight of 1464 kDa, the number-average molecular weight of 694 kDa, and the polydispersity index of 2.11. Congo red experiment confirmed the absence of a triple helix conformation. Scanning electron microscopy showed that EPS53 displayed a three-dimensional fibrous structure covered with flakes. The in vitro findings indicated that EPS53 enhanced phagocytosis ability, reactive oxygen species (ROS) production, and cytokine levels of macrophages via the TLR4-mediated NF-κB/MAPK signaling pathways as confirmed by immunofluorescence staining experiments, inhibition blocking experiments, and Western blot assay. Additionally, the in vivo experiments demonstrated that EPS53 significantly increased macrophage and neutrophil number while enhancing NO and ROS levels in zebrafish larvae; thus, providing further evidence for the immunomodulatory efficacy of EPS53.

Abstract
The crude polysaccharide of Bletilla striata in this study was extracted by water extraction and alcohol precipitation and further purified by gel column to yield the purified component Bletilla striata polysaccharide (BSP). Its structure and innate immune regulation activity were studied. BSP mainly comprises mannose and glucose, with a monosaccharide molar ratio of 2.9:1 and a weight-average molecular weight of 28,365 Da. It is a new low-molecular-weight water-soluble neutral glucomannan. BSP contains a → 6)-β-Manp-(1→, →4)-β-Glcp-(1→, →4)-β-Manp-(1 → and →3)-α-Manp-(1 → linear main chain, containing β-Glcp-(1 → and β-Manp-(1 → two branched chain fragments were connected to the Man residue at position 4. BSP can enhance the anti-infection ability of Caenorhabditis elegans against Pseudomonas aeruginosa, significantly improve the phagocytic ability of RAW264.7 macrophages, stimulate the secretion of NO and TNF-α, and have good innate immune regulation activity. These findings guide the use of Bletilla striata polysaccharides with immunomodulatory action.

Abstract
A new polysaccharide, named SP40015A01, was obtained from Saposhnikoviae Radix by water extraction, isolation and purification. SP40015A01 (9.7 × 105 Da) is composed of Rhamnose (Rha), Galacturonic acid (GalA), Galactose (Gal), and Arabinose (Ara) with the proportion of 1.6:85.6:5.8:7.6. The backbone of SP40015A01 is composed of 3-α-GalAp, 2-α-GalAp, 2,3-β-GalAp and 2,3-β-Galp, and branched at C3 of 2,3-β-GalAp, C3 of 2,3-β-Galp. Zebrafish experiments were used to explore the immunomodulatory activity of SP40015A01. Results showed that SP40015A01 could significantly improve the neutrophils density of immunocompromised zebrafish and reduce the content of nitric oxide (NO) and interleukin-1β (IL-1β). This study demonstrated that SP40015A01 has significant immunomodulatory activity, which can improve the neutrophils density and reduce inflammatory factor content, suggesting SP40015A01 may be a potential immunomodulator in Saposhnikoviae Radix (SR) for treatment of hypoimmunity related disease. This study supplemented the research on the polysaccharide components in traditional Chinese medicine and provided a scientific explanation for the development and clinical applications of SR.

Abstract
Fungal polysaccharides have been explored by many for both structural studies and biological activities, but few studies have been done on the extracellular polysaccharides of Dictyophora rubrovalvata, so a new exopolysaccharide was isolated from Dictyophora rubrovalvata and its structure and its immunological activity were investigated. The crude exopolysaccharide (EPS) was purified by DEAE52 cellulose and Sephadex G-200 to obtain a new acidic polysaccharide (DR-EPS). DR-EPS (2.66 × 103 kDa) was consisted mainly of mannose, glucose, galactose and glucuronic acid with a molar ratio of 1: 0.86: 0.20: 0.01. In addition, DR-EPS increased the phagocytic activity of RAW264.7 cells up to 2.67 times of the blank control group. DR-EPS improved intracellular nucleic acid and glycogen metabolism as observed by AO and PAS staining. DR-EPS(40 μg/mL) promoted NO production up to 30.66 μmol, enhanced acid phosphatase (ACP) and superoxide dismutase (SOD) activities, with activity maxima of 660 U/gprot and 96.27 U/mgprot, respectively, and DR-EPS (160 μg / mL) significantly increased the lysozyme content as 2.73 times of the control group. The good immunological activity of extracellular polysaccharides of Dictyophora rubrovalvata provides directions for the use of fermentation broths.

Abstract
The purpose of this study was to identify ovalbumin-derived immunomodulatory peptides by in vitro cell experiments, de novo sequencing, and molecular docking. Ovalbumin hydrolysates were prepared by two enzymes (alkaline protease and papain) individually, sequentially, or simultaneously, respectively. The simultaneous enzymatic hydrolysate (OVAH) had a high degree of hydrolysis (38.12 ± 0.48%) and exhibited immune-enhancing and anti-inflammatory activities. A total of 160 peptides were identified by LC-MS/MS in OVAH. Three novel peptides NVMEERKIK, ADQARELINS, and WEKAFKDE bound to TLR4-MD2 through hydrogen bonds and hydrophobic interactions with high binding affinity and binding energies of -181.40, -178.03, and -168.12 kcal/mol, respectively. These three peptides were synthesized and validated for two-way immunomodulatory activity. NVMEERKIK exhibiting the strongest immunomodulatory activity, increased NO and TNF-α levels by 128.69 and 38.01%, respectively, in normal RAW264.7 cells and reduced NO and TNF-α levels by 27.31 and 39.13%, respectively, in lipopolysaccharide-induced inflammatory RAW264.7 cells. Overall, this study first revealed that ovalbumin could be used as an immunomodulatory source for controlling inflammatory factor secretion.

Abstract
A neutral Polygonatum cyrtonema polysaccharide (NPCP) was isolated and purified from Polygonatum cyrtonema by various chromatographic techniques, including DEAE-52 and Sephadex-G100 chromatography. The structure of NPCP was characterized by HPLC, HPGPC, GC-MS, FT-IR, NMR, and SEM. Results showed that NPCP is composed of glucose (55.4%) and galactose (44.6%) with a molecular weight of 3.2 kDa, and the sugar chain of NPCP was →1)-α-D-Glc-(4→1)-β-D-Gal-(3→. In vitro bioactivity experiments demonstrated that NPCP significantly enhanced macrophages proliferation and phagocytosis while inhibiting the M1 polarization induced by LPS as well as the M2 polarization induced by IL-4 and IL-13 in macrophages. Additionally, NPCP suppressed the secretion of IL-6 and TNF-α in both M1 and M2 cells but promoted the secretion of IL-10. These results suggest that NPCP could serve as an immunomodulatory agent with potential applications in anti-inflammatory therapy.

Achyranthes bidentata polysaccharides improve cyclophosphamide-induced adverse reactions by regulating the balance of cytokines in helper T cells. Int J Biol Macromol 2024; 265:130736. [PMID: 38479672 DOI: 10.1016/j.ijbiomac.2024.130736] [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: 09/15/2023] [Revised: 03/04/2024] [Accepted: 03/06/2024] [Indexed: 04/18/2024]
Abstract
The manuscript aimed to study the immune function maintenance effect of Achyranthes bidentata polysaccharides (ABPs). The mice were divided into the control group, cyclophosphamide-induced (CTX) group, and ABPs-treated (ABP) group. The results showed that, compared with the CTX group, ABPs could significantly improve the spleen index and alleviate the pathological changes in immune organs. Ex vivo study of whole spleen cells, the levels of interleukin-2 (IL-2), interleukin-6 (IL-6), interferon-γ (IFN-γ), and tumor necrosis factor-α (TNF-α) were increased. The proliferation of lymphocytes and the proportion of CD3+CD4+ Th cells in peripheral blood mononuclear cells were increased. The transcription of GATA-3, Foxp3, and ROR γ t were decreased, while the transcription of T-bet was increased. The transcriptome sequencing analysis showed that the differentially expressed genes (DEGs) caused by ABPs-treated were mostly downregulated in CTX-induced mice. The Th2-related genes were significantly enriched in DEGs, with representative genes, including Il4, II13, Il9, etc., while increasing the expression of immune effector genes simultaneously, including Ccl3, Ccr5, and Il12rb2. It was suggested that ABPs possibly regulated the balance of cytokines in helper T cells to ameliorate the immune function of CTX-induced mice.

Abstract
In this study, a novel homogeneous polysaccharide (HVP-1) was purified from the Volvariella volvacea. Its structural characteristics and anti-oxidant activity in vitro were further evaluated. The results revealed that HVP-1 was composed of mannose, glucose, galactose and arabinose in a molar ratio (mol %) of 55.37: 15.74: 25.20: 3.69. Its main chain consisted of →4)-β-D-Galp-(1→, →6)-α-D-Glcp-(1→, →3)-α-D-Glcp-(1→, →4)-β-D-Manp-(1→ and →3,6)-β-D-Manp-(1→. The branched structure α-L-Araf-(1→, →2)-β-D-Glcp-(1→ and →6)-β-D-Manp-(1→ were connected to →3,6)-β-D-Manp-(1→ through the O-3 position. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) showed that HVP-1 had porous sheet-like structure with a triple helix conformation. Anti-oxidant activity experiments showed that HVP-1 alleviated H2O2-induced oxidative damage by reducing the accumulation of reactive oxygen species, increasing the activity of related enzymes in cells, and activating the Nrf2/HO-1 signaling pathway. These results suggested that HVP-1 had the potential to be used as a natural anti-oxidant in functional foods and pharmaceuticals.

[PMID: 37984545 DOI: 10.1016/j.jep.2023.117425] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 10/26/2023] [Accepted: 11/12/2023] [Indexed: 11/22/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Saposhnikoviae Radix, the dry root of Saposhnikovia divaricatee (Turcz.) Schischk, is a traditional chinese medicine used for the treatment of cold, headache, and skin pruritus. AIM OF THE STUDY This study aimed to identify novel active polysaccharides from Saposhnikovia divaricatee (Turcz.) Schischk and clarify their structures and bioactivities. MATERIALS AND METHODS The structure of polysaccharides was clarified by PMP-HPLC, methylation analysis, particle acid hydrolysis analysis and NMR analysis. The anti-allergic and antioxidant activities of polysaccharides were evaluated on allergic reaction model in RBL-2H3 cells and oxidative damage model of C. elegans. RESULTS We purified a novel homogenous polysaccharide named SP-3 from Saposhnikovia divaricatee (Turcz.) Schischk and its molecular weight was determined as 3.096 × 104 Da. Monosaccharide composition analysis revealed that SP-3 was composed of mannose, rhamnose, galacturonic acid, glucose, galactose, and arabinose (1.85: 5.22: 38.06: 2.36: 23.25: 29.26). The main linkage type of SP-3 was a repeat unit of →4,6)-β-D-Galp-(1 → 4)-α-D-GalpA-(1 → . The branches of SP-3 contained T-linked-α-L-Araf and 1,3,4-linked-α-L-Rhap. It was observed that SP-3 inhibited β-HEX release and inflammatory factors in RBL-2H3 cells subject to IgE stimulant. Meanwhile, SP-3 increased the mean lifespan of Caenorhabditis elegans under oxidative stress, reduced ROS content and increased antioxidant enzyme activities of C. elegans, potentially through activating the SOD-3. CONCLUSIONS A novel homogenous polysaccharide was identified from Saposhnikovia divaricatee (Turcz.) Schischk, and this polysaccharide SP-3 played key roles for the anti-allergic and antioxidant activities.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Saposhnikoviae Radix (SR) is a traditional Chinese medicine, known as "Fangfeng". As one of the main active components, Saposhnikoviae Radix polysaccharides (SP) demonstrated a range of biological activities, especially immunity regulation activity. AIMS OF THE STUDY This study aimed at exploring whether polysaccharides have activity after degradation, then discovering the potential effective fragments of SP. MATERIALS AND METHODS Here we establish the chromatographic fingerprints method for 32 batches of 1-phenyl-3-methyl-5-pyrazolone (PMP) derivatives of oligosaccharides by HPLC, meanwhile evaluating its immunomodulatory activity in vivo. Then, the potential effective fragments of SP were screened out based on the spectrum-effect relationship analysis between fingerprints and the pharmacological results. Besides, liquid chromatography ion trap-time of flight mass spectrometry (LC-IT-TOF MS) coupled with multiple data-mining techniques was used to identify the potential effective oligosaccharides. RESULTS These findings showed that the hydrolysate of SP have significant immunomodulatory, and the immunity regulation activity varies under different hydrolysis conditions. The 4 potential effective peaks of the hydrolysate of SP were mined by spectrum-effect relationship. Finally, the chemical structure of 4 potential effective oligosaccharide fragments of SP was elucidated based on LC-IT-TOF MS. F10 was inferred tentatively to be Hex1→6Hex1→6Hex1→6Hex1→6Hex1→6Gal; F18 was confirmed to be Rhamnose; F14 was inferred tentatively to be Hex1→4Hex1→ 4Hex1→4Gal and F25 was tentatively inferred to be Ara1→6Gal. CONCLUSIONS This study may provide a sound experimental foundation in the exploration of the active fragments from macromolecular components with relatively complex structures such as polysaccharides.

Antioxidants (Basel) 2024; 13:136. [PMID: 38397734 PMCID: PMC10886326 DOI: 10.3390/antiox13020136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 12/28/2023] [Accepted: 01/09/2024] [Indexed: 02/25/2024] Open
Abstract
The present study assessed the protective effects and underlying mechanisms of mulberry leaf polysaccharides (MLPs) against hydrogen peroxide (H2O2)-induced oxidative stress injury in the peripheral blood leukocytes (PBLs) of Megalobrama amblycephala. Five treatment groups were established in vitro: the NC group (PBLs incubated in an RPMI-1640 complete medium for 4 h), the HP group (PBLs incubated in an RPMI-1640 complete medium for 3 h, and then stimulated with 100 μM of H2O2 for 1 h), and the 50/100/200-MLP pre-treatment groups (PBLs were pre-treated with MLPs (50, 100, and 200 μg/mL) for 3 h, and then stimulated with 100 μM of H2O2 for 1 h). The results showed that MLP pre-treatment dose-dependently enhanced PBLs' antioxidant capacities. The 200 μg/mL MLP pre-treatment effectively protected the antioxidant system of PBLs from H2O2-induced oxidative damage by reducing the malondialdehyde content and lactic dehydrogenase cytotoxicity, and increasing catalase and superoxide dismutase activities (p < 0.05). The over-production of reactive oxygen species, depletion of nicotinamide adenine dinucleotide phosphate, and collapse of the mitochondrial membrane potential were significantly inhibited in the 200-MLP pre-treatment group (p < 0.05). The expressions of endoplasmic reticulum stress-related genes (forkhead box O1α (foxO1α), binding immunoglobulin protein (bip), activating transcription factor 6 (atf6), and C/EBP-homologous protein (chop)), Ca2+ transport-related genes (voltage-dependent anion-selective channel 1 (vdac1), mitofusin 2 (mfn2), and mitochondrial Ca2+ uniporter (mcu)), and interleukin 6 (il-6) and bcl2-associated x (bax) were significantly lower in the 200-MLP pre-treatment group than in the HP group (p < 0.05), which rebounded to normal levels in the NC group (p > 0.05). These results indicated that MLP pre-treatment attenuated H2O2-induced PBL oxidative damage in the M. amblycephala by inhibiting endoplasmic reticulum stress and maintaining mitochondrial function. These findings also support the possibility that MLPs can be exploited as a natural dietary supplement for M. amblycephala, as they protect against oxidative damage.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix Saposhnikoviae (R. Saposhnikoviae), commonly known as FangFeng, is a renowned medicinal herb in China extensively utilized in traditional Chinese medicine. It expels pathogenic wind from the body surface, alleviates pain by removing dampness, and relieves convulsion. Therefore, it is mainly used for treating exterior syndrome, itchy wind papules, rheumatic arthralgia, and splenic asthenia-induced dampness. R. saposhnikoviae has important medicinal value, and the polysaccharide component is one of its important active ingredients. AIM OF THE REVIEW This review summarizes the factors influencing the content of polysaccharides in R. Saposhnikoviae (PRSs), the techniques employed for their extraction, separation, and purification, their structural characterization, and their biological activities. MATERIALS AND METHODS Relevant research reports on PRSs were collected from the Chinese National Knowledge Infrastructure, Web of Science, PubMed, Wanfang Data Knowledge Service Platform, China Master Theses Full-text Database, and China Doctoral Dissertations Full-text Database. RESULTS The content of PRSs can vary depending on cultivation methods and harvesting time. PRSs were extracted using various extraction techniques such as hot water, ultrasonic-assisted, microwave-assisted, and enzymatic extractions, as well as water extraction and alcohol precipitation. Effective purification methods involve protein removal using trifluoro-trichloroethane and the decolorization of the polysaccharide using column chromatography with D280 anion exchange resins. Current research highlights the significant pharmacological activities of PRSs in R. Saposhnikoviae, including immunomodulatory, antioxidant, anti-allergic, anti-cancer, and anti-osteoporotic effects as well as prevention of calcium loss and maintenance of mucosal function. CONCLUSIONS PRSs play a crucial role as bioactive constituents of R. Saposhnikoviae, exhibiting diverse biological activities and promising applications. A deeper understanding of PRSs will contribute to the improved utilization of R. Saposhnikoviae and the development of related derivatives of the active ingredients.
