[PMID: 38270668 DOI: 10.1007/s11033-023-09137-2] [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: 10/25/2023] [Accepted: 12/08/2023] [Indexed: 01/26/2024]
Abstract
BACKGROUND Achyranthes aspera L. (family Amaranthaceae) is a plant species valued in Ayurveda for the treatment of respiratory ailments. Scientific validation of its antiallergic potential was aimed. METHODS AND RESULTS Three extracts of A. aspera [aqueous (AaAq), hydroalcoholic (AaHA), ethanolic (AaEt)] were evaluated for their potency against C48/80-induced anaphylaxis in mice at 200 mg/kg BW oral dose. The effective dose of the most potent extract was determined through its effect on C48/80-induced anaphylaxis, and was further analyzed through its effect on mast cell degranulation, histamine-induced bronchospasm and ovalbumin (OVA)-induced asthma in a murine model. Among the three extracts, AaAq was found to be most potent at 200 mg/kg BW. AaAq 400 (400 mg/kg BW) was found to be the most effective dose in terms of inhibition of mortality and histamine level. AaAq 400 prevented the peritoneal and mesenteric mast cells from undergoing morphological changes due to degranulation induced by C48/80. Further, AaAq 400 delayed pre-convulsive time in histamine-induced bronchospasm. In the OVA-induced asthma model, AaAq 400 inhibited the level of inflammatory cell count in blood, bronchoalveolar lavage fluid and peritoneal fluid of mice. The Th2 cytokines (IL-4, IL-5, IL-13), TGF-β and OVA-specific IgE were also reduced as evaluated by ELISA. Also, significant reduction in IL-5 (an eosinophilia indicator) transcript abundance and lung inflammatory score was observed. AaAq was safe up to 4000 mg/kg BW. CONCLUSIONS Thus AaAq 400 possesses significant antiallergic potential and acts via attenuation of C48/80-induced anaphylaxis and inhibition of mast cell degranulation. It reduces pre-convulsive dyspnea in histamine-induced bronchospasm and Th2 cytokines in asthmatic mice.

Harms in Bubble-Type Bioreactors-Growth Characteristics, Triterpene Glycosides Accumulation and Biological Activity. PLANTS (BASEL, SWITZERLAND) 2023; 12:3641. [PMID: 37896105 PMCID: PMC10610180 DOI: 10.3390/plants12203641] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 10/12/2023] [Accepted: 10/19/2023] [Indexed: 10/29/2023]
Abstract
Polyscias fruticosa (L.) Harms, or Ming aralia, is a medicinal plant of the Araliaceae family, which is highly valued for its antitoxic, anti-inflammatory, analgesic, antibacterial, anti-asthmatic, adaptogenic, and other properties. The plant can be potentially used to treat diabetes and its complications, ischemic brain damage, and Parkinson's disease. Triterpene glycosides of the oleanane type, such as 3-O-[β-D-glucopyranosyl-(1→4)-β-D-glucuronopyranosyl] oleanolic acid 28-O-β-D-glucopyranosyl ester (PFS), ladyginoside A, and polysciosides A-H, are mainly responsible for biological activities of this species. In this study, cultivation of the cell suspension of P. fruticosa in 20 L bubble-type bioreactors was attempted as a sustainable method for cell biomass production of this valuable species and an alternative to overexploitation of wild plant resources. Cell suspension cultivated in bioreactors under a semi-continuous regime demonstrated satisfactory growth with a specific growth rate of 0.11 day-1, productivity of 0.32 g (L · day)-1, and an economic coefficient of 0.16 but slightly lower maximum biomass accumulation (~6.8 g L-1) compared to flask culture (~8.2 g L-1). Triterpene glycosides PFS (0.91 mg gDW-1) and ladyginoside A (0.77 mg gDW-1) were detected in bioreactor-produced cell biomass in higher concentrations compared to cells grown in flasks (0.50 and 0.22 mg gDW-1, respectively). In antibacterial tests, the minimum inhibitory concentrations (MICs) of cell biomass extracts against the most common pathogens Staphylococcus aureus, methicillin-resistant strain MRSA, Pseudomonas aeruginosa, and Escherichia coli varied within 250-2000 µg mL-1 which was higher compared to extracts of greenhouse plant leaves (MIC = 4000 µg mL-1). Cell biomass extracts also exhibited antioxidant activity, as confirmed by DPPH and TEAC assays. Our results suggest that bioreactor cultivation of P. fruticosa suspension cell culture may be a perspective method for the sustainable biomass production of this species.

Antioxidant and Anti-Inflammatory Mechanisms of Lipophilic Fractions from Polyscias fruticosa Leaves Based on Network Pharmacology, In Silico, and In Vitro Approaches. Foods 2023; 12:3643. [PMID: 37835296 PMCID: PMC10573055 DOI: 10.3390/foods12193643] [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: 09/04/2023] [Revised: 09/26/2023] [Accepted: 09/28/2023] [Indexed: 10/15/2023] Open
Abstract
Polyscias fruticosa leaf (PFL) has been used in food and traditional medicine for the treatment of rheumatism, ischemia, and neuralgia. However, the lipophilic components of PFL and their biological properties remain unknown. This study, integrating network pharmacology analysis with in silico and in vitro approaches, aimed to elucidate the antioxidant and anti-inflammatory capacities of lipophilic extracts from PFL. A total of 71 lipophilic compounds were identified in PFL using gas chromatography-mass spectrometry. Network pharmacology and molecular docking analyses showed that key active compounds, mainly phytosterols and sesquiterpenes, were responsible for regulating core target genes, such as PTGS2, TLR4, NFE2L2, PRKCD, KEAP1, NFKB1, NR1l2, PTGS1, AR, and CYP3A4, which were mostly enriched in oxidative stress and inflammation-related pathways. Furthermore, lipophilic extracts from PFL offered powerful antioxidant capacities, as evident in our cell-free antioxidant assays. These extracts also provided a protection against oxidative stress by inducing the expression of catalase and heme oxygenase-1 in lipopolysaccharide (LPS)-treated RAW 264.7 cells. Additionally, lipophilic fractions from PFL showed anti-inflammatory potential in downregulating the level of pro-inflammatory factors in LPS-treated macrophages. Overall, these findings provide valuable insights into the antioxidant and anti-inflammatory properties of lipophilic extracts from PFL, which can be used as a fundamental basis for developing nutraceuticals and functional foods.

Neuroprotective Effects of Ethanol Extract of Polyscias fruticosa (EEPF) against Glutamate-Mediated Neuronal Toxicity in HT22 Cells. Int J Mol Sci 2023; 24:ijms24043969. [PMID: 36835378 PMCID: PMC9959701 DOI: 10.3390/ijms24043969] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 02/03/2023] [Accepted: 02/10/2023] [Indexed: 02/18/2023] Open
Abstract
In traditional herbal medicine, the Polyscias fruticosa has been frequently used for the treatment of ischemia and inflammation. Oxidative stress mediated by elevated glutamate levels cause neuronal cell death in ischemia and various neurodegenerative diseases. However, so far, the neuroprotective effects of this plant extract against glutamate-mediated cell death have not been investigated in cell models. The current study investigates the neuroprotective effects of ethanol extracts of Polyscias fruticosa (EEPF) and elucidates the underlying molecular mechanisms of EEPFs relevant to neuroprotection against glutamate-mediated cell death. The oxidative stress-mediated cell death was induced by 5 mM glutamate treatment in HT22 cells. The cell viability was measured by a tetrazolium-based EZ-Cytox reagent and Calcein-AM fluorescent dye. Intracellular Ca2+ and ROS levels were measured by fluorescent dyes, fluo-3 AM and 2',7'-dichlorodihydrofluorescein diacetate (DCF-DA), respectively. Protein expressions of p-AKT, BDNF, p-CREB, Bax, Bcl-2, and apoptosis-inducing factor (AIF) were determined by western blot analysis. The apoptotic cell death was measured by flow cytometry. The in vivo efficacy of EEPF was evaluated using the Mongolian gerbil mouse by surgery-induced brain ischemia. EEPF treatment showed a neuroprotective effect against glutamate-induced cell death. The EEPF co-treatment reduced the intracellular Ca2+ and ROS and apoptotic cell death. Furthermore, it recovered the p-AKT, p-CREB, BDNF, and Bcl-2 levels decreased by glutamate. The EEPF co-treatment suppressed the activation of apoptotic Bax, the nuclear translocation of AIF, and mitogen-activated protein kinase (MAPK) pathway proteins (ERK1/2, p38, JNK). Further, EEPF treatment significantly rescued the degenerative neurons in the ischemia-induced Mongolian gerbil in vivo model. EEPF exhibited neuroprotective properties that suppress glutamate-mediated neurotoxicity. The underlying mechanism of EEPF is increasing the level of p-AKT, p-CREB, BDNF, and Bcl-2 associated with cell survival. It has therapeutic potential for the treatment of glutamate-mediated neuropathology.

Abstract
Asthma is a chronic inflammatory disease of the respiratory tract in which the numerous immune cells, including eosinophils, neutrophils, macrophages, T-lymphocytes, mast cells and epithelial lining play key roles. The numerous anti-asthmatic drugs are available in modern medicine to treat asthma, but they have several disadvantages, including side effects and the cost variations, which compromise treatment compliance. The literature review reveals that traditional herbal medicines have good potential as alternative treatment and management for asthma. However, communities hesitated to use the traditional herbal medicines due to lack of established mechanism of action about their anti-asthmatic potential. The present review aimed to summarise the information stated in the literature about the potential effect of traditional medicinal plants (TMPs) conferring protection against ovalbumin (OVA)-induced asthma model. The literature search was conducted in database like PubMed, Scopus, Google Scholar and ScienceDirect. After screening through the literature from 2011 to date, a total of 27 medicinal plants and two polyherbal extracts have been reported to be used as traditional herbal medicines and also utilised to be tested against OVA-induced asthma, were included. We found them to be an important alternative source of treatment for asthma, since some have comparable efficacies with drugs commonly used in the modern system against asthma. All the reported medicinal plants confirmed their traditional use against asthma or its related inflammation. The present review provides faith in traditional information and also offers new insight into the potential of natural products against asthma.

Abstract
BACKGROUND Many bone-related diseases such as osteoporosis and rheumatoid arthritis are commonly associated with the excessive activity of osteoclasts. Polyscias fruticosa has been used as traditional medicine for the treatment of ischemia and inflammation and also eaten as a salad. However, its effect on the bone related diseases has not been investigated yet. PURPOSE This study aimed to investigate the effect of ethanol extract of P. fruticosa on RANKL-induced osteoclastogenesis in vitro and LPS-induced bone loss in mouse, and evaluate anti-osteoclastogenic activities of its major constituents. METHODS BMMs or RAW264.7 cells were treated with ethanol extract from P. fruticose leaves (EEPL), followed by an evaluation of cell viability, RANKL-induced osteoclast differentiation, actin-ring formation, and resorption pits activity. Effects of EEPL on RANKL-induced phosphorylation of MAPKs were evaluated by Western blotting. The expression levels of NFATc1 and c-Fos were evaluated by Western blotting or immunofluorescence assay. The expression levels of osteoclast-specific marker genes were evaluated by Western blotting and reverse transcription-qPCR analysis. A LPS-induced murine bone loss model was used to evaluate the protective effect of EEPL on inflammation-induced bone loss. HPLC analysis was performed to identify the major constituents of EEPL. RESULTS EEPL significantly inhibited RANKL-induced osteoclast differentiation by decreasing the number of osteoclasts, osteoclast actin-ring formation, and bone resorption. EEPL suppressed RANKL-induced phosphorylation of p38 and JNK MAPKs, as well as the expression of c-Fos and NFATc1. EEPL decreased the expression levels of osteoclast marker genes, including MMP-9, TRAP and CtsK. Mice treated with EEPL significantly protected the mice from LPS-induced osteoclast formation and bone destruction as indicated by micro-CT and histological analysis of femurs. We also identified 3-O-[β-d-glucopyranosyl-(1→4)-β-d-glucuronopyranosyl] oleanolic acid 28-O-β-d-glucopyranosyl ester (1) and quercitrin (3) as the active constituents in EEPL for inhibiting RANKL-induced osteoclast differentiation. CONCLUSION The results showed that EEPL exerted anti-osteoclastogenic activity in vitro and in vivo by inhibiting RANKL-induced osteoclast differentiation and function, and suggested that EEPL could have beneficial applications for preventing or inhibiting osteoclast-mediated bone diseases.

Abstract
Phytochemical investigation of Polyscias guilfoylei leaves extract (PGE) led to the isolation of nine compounds, that is, ent-labda-8(17),13-diene-15,18-diol (1), stigmasterol (2), spinasterol (3), N-(1,3-dihydroxyoctadecan-2-yl) palmitamide (4), panaxydiol (5), 3-O-β-d-glucopyranosylstigmasta-5,22-diene-3-β-ol (6), (8Z)-2-(2 hydroxypentacosanoylamino) octadeca-8-ene-1,3,4-triol (7), 4-hydroxybenzoic acid (8), and tamarixetin 3,7-di-O-α-L-rhamnopyranoside (9). Compound 4 is reported in this study for the first time in nature whereas compound 9 is reported for the second time. Structural elucidation of the compounds was carried out using Nuclear Magnetic Resonance and Electrospray Ionization coupled with Mass Spectrometry spectroscopic analyses. PGE and compounds 4 and 9 exhibited weak cytotoxicity against both MCF-7 and HCT-116 cell lines using 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide assay. The antimicrobial activity of PGE and compounds 4 and 9 was evaluated using the agar diffusion method. Escherichia coli was the most susceptible Gram-negative bacteria toward PGE with a minimum inhibitory concentration value of 9.76 μg/mL, whereas compounds 4 and 9 did not show any antimicrobial activity. Compound 4 exhibited promising inhibition of histamine release using U937 human monocytes with an IC50 value of 38.65 μg/mL.

Abstract
Three bisdesmosidic saponins 3-O-[β-D-glucopyranosyl-(1→4)-β-D-glucuronopyranosyl] oleanolic acid 28-O-β-D-glucopyranosyl ester (1), polyscioside D (2), and 3-O-{β-D-glucopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-β-D-glucuronopyranosyl}oleanolic acid 28-O-β-D-glucopyranosyl-(1→2)-β-D-galactopyranosyl ester (3) were isolated from a methanol extract ofPolyscias fruticosa(L.) Harms leaves. Compound1was obtained as a main constituent and compound3was reported for the first time and named as polyscioside I. Saponin1inhibited porcine pancreasα-amylase and yeastα-glucosidase activities while2and3were inactive. Synergistic inhibitory effect onα-amylase was observed from the combination of low concentrations of1and acarbose. The findings suggest the use ofP. fruticosaand its major saponin1for the prevention and treatment of diabetes and its complications.
