Polymers (Basel) 2024; 16:1705. [PMID: 38932054 PMCID: PMC11207487 DOI: 10.3390/polym16121705] [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: 05/13/2024] [Revised: 06/02/2024] [Accepted: 06/06/2024] [Indexed: 06/28/2024] Open
Abstract
Polysaccharides (AOPs) were extracted from Alpiniae oxyphyllae fructus using three distinct methods: hot water (AOP-HW), hydrochloric acid (AOP-AC), and NaOH/NaBH4 (AOP-AL). This study systematically investigated and compared the physicochemical properties, structural characteristics, antioxidant activities, and α-amylase inhibitory activities of the extracted polysaccharides. Among the three AOPs, AOP-AC exhibited the highest yield (13.76%) and neutral sugar content (80.57%), but had the lowest molecular weight (121.28 kDa). Conversely, AOP-HW had the lowest yield (4.54%) but the highest molecular weight (385.42 kDa). AOP-AL was predominantly composed of arabinose (28.42 mol%), galacturonic acid (17.61 mol%), and galactose (17.09 mol%), while glucose was the major sugar in both AOP-HW (52.31 mol%) and AOP-AC (94.77 mol%). Functionally, AOP-AL demonstrated superior scavenging activities against DPPH, hydroxyl, and ABTS radicals, whereas AOP-AC exhibited the strongest inhibitory effect on α-amylase. These findings indicate that the extraction solvent significantly influences the physicochemical and biological properties of AOPs, thus guiding the selection of appropriate extraction methods for specific applications. The results of this study have broad implications for industries seeking natural polysaccharides with antioxidant and enzymatic inhibitory properties.

Tie Y, Sun Z, Tong X, Cheng M, Wu Y, Shi Z, Xu P, Xue M, Xu L, Zhou X. Multi-omic analysis revealed the therapeutic mechanisms of Alpinia oxyphylla fructus water extract against bladder overactivity in spontaneously hypertensive rats. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 123:155154. [PMID: 37976696 DOI: 10.1016/j.phymed.2023.155154] [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: 06/21/2023] [Revised: 09/25/2023] [Accepted: 10/16/2023] [Indexed: 11/19/2023]
Abstract
OBJECTIVE Alpinia oxyphylla fructus without impurities and shells is called "Yi-Zhi-Ren" (YZR) in Chinese, and traditionally used to alleviate enuresis. The aim of this study was to investigate the effects and underlying mechanisms of YZR in the treatment of overactive bladder (OAB) in spontaneously hypertensive rats (SHR), a vascular disorder-related OAB model. METHODS A 3-week administration of YZR water extract (p.o.) was done, followed by urodynamics to measure bladder parameters. Changes in bladder structure were observed through H&E staining and Masson's staining. An integrated approach involving network pharmacology, transcriptomics and metabolomics was employed to elucidate the potential mechanisms of YZR, and the key proteins involved in the mechanisms were validated by Western blotting. Additionally, network pharmacology was used to predict the relationship between YZR's active components and validated proteins. RESULTS YZR treatment significantly improved the bladder storage parameters, tightened the detrusor layer, reduced inflammatory infiltration, and decreased collagen proportion in the SHR bladder. These results indicated that YZR water extract can alleviate OAB symptoms and improve bladder structure. Integrated analysis suggested that YZR may affect extracellular matrix-receptor interaction and calcium signaling pathway. Western blotting results further confirmed that the reduction in key proteins, such as TGFβ1, p-SMAD3, collagen III, Gq and PLCβ1, involved in collagen synthesis and calcium signaling pathways after YZR treatment. Network pharmacology predicted that sitosterol, chrysin, and nootkatone were potential components responsible for YZR's therapeutic effect on OAB. CONCLUSION YZR's mechanisms of action in treating OAB involved the TGFβ1-SMAD3 signaling pathway-related collagen synthesis and Gq-PLCβ1 calcium signaling pathway, which are associated with detrusor contraction frequency and strength, respectively.

Abstract
The fruits of Alpinia oxyphylla have been used for centuries in China as both edible resources and traditional Chinese medicine. In order to identify structurally interesting and bioactive constituents from the fruits of A. oxyphylla, bioassay-guided fractionation and purification of the crude extracts were performed, which led to the isolation of 38 sesquiterpenoids, including six previously undescribed eremophilane sesquiterpenoids (1-6), six new cadinane sesquiterpenoids (23-24, 26-29), and 26 known analogues (7-22, 25 and 31-38). The structures of these compounds were elucidated by comprehensive spectroscopic data analysis, single crystal X-ray diffraction, quantum chemistry calculations (13C-NMR and ECD), and Mo2(OAc)4 reaction. Several of the isolated compounds (8, 13, 17, 18, 30, 31 and 35) showed moderate to strong inhibition of the secretion of cytokines (NO, TNF-α and IL-6) in LPS-stimulated BV-2 cells. Furthermore, western blot, immunofluorescence, and real-time PCR assays indicated that 18 could down-regulate the mRNA levels of TNF-α, IL-6, COX-2, and iNOS and the protein expression of COX-2 and iNOS. Meanwhile, 18 was able to partially inhibit the phosphorylation of ERK1/2, JNK, and p38. Thus, the discovery of structurally diverse anti-inflammatory sesquiterpenoids from the fruits of A. oxyphylla in this study could benefit the further development and utilization of this plant.

Abstract
The phytochemical investigation of the fruits of Alpinia oxyphylla led to the isolation and identification of 40 structurally diverse sesquiterpenoids, including 17 new eudesmane sesquiterpenoids (1-17) and 23 known analogues (18-40). Among the isolates, 14 and 17 were unusual rearranged eudesmane sesquiterpenoids, featuring rare 5/6-fused and 6/8-fused bicyclic carbon skeleton, respectively; 15 and 16 were the novel 6,7-seco-eudesmane sesquiterpenoids isolated from plant-origin for the first time, 1 and 3-6 were rare nor-eudesmane sesquiterpenoids. Their structures were elucidated by comprehensive spectroscopic data analysis (NMR, HRESIMS, IR, UV), single crystal X-ray diffraction, and quantum chemistry calculations (ECD and 13C NMR). Moreover, all isolates were evaluated by measuring their inhibitory effect on nitric oxide (NO) in LPS-stimulated BV-2 cells. As a result, compounds 11, 20, 24 and 40 showed moderate to strong inhibition on NO productions, with IC50 values ranging from 21.63 to 60.70 μM. Meanwhile, these compounds also partially decreased the secretion of TNF-α and IL-6 in LPS-stimulated BV-2 cells. Furthermore, 20 could down-regulate protein expressions (COX-2 and iNOS) and observably inhibit the mRNA expressions of TNF-α, IL-6, COX-2 and iNOS. In this study, the discovery of structurally diverse anti-inflammatory sesquiterpenoids from the fruits of A. oxyphylla could benefit the further development and utilization of this plant.

Abstract
Polysaccharides are important components of Alpiniae oxyphyllae fructus that have been shown to exhibit significant immunomodulatory activity in our previous study. However, whether and how A. oxyphyllae fructus polysaccharides (AOFP) affect macrophages has not been determined. To further study the immunomodulatory activity of AOFP, the effect of AOFP on RAW264.7 cell activation was investigated in the present work. The results showed that AOFP2 significantly increased the phagocytic activity of RAW264.7 macrophages. AOFP2 promoted the secretion of TNF-α, IL-6, IL-10, TGF-β, NO and iNOS and enhanced the Th2-type immune response via its activation effect on macrophages. Additionally, the structure of AOFP2 was characterized in the present study, as the structural features of polysaccharides determine their biological activities. AOFP2 was only composed of glucose, exhibiting an average molecular weight of 44.3 kDa. Furthermore, the infrared spectroscopy, methylation and nuclear magnetic resonance results indicated that AOFP2 consisted of → 4)-α-D-Glcp-(1→, →4,6)-α-D-Glcp-(1 → and T-α-Glcp.

Abstract
Polysaccharide is the main active component of okra (Abelmoschus esculentus L.) and it can effectively stimulate the activation of macrophages. However, the immune regulatory mechanism is still not clear. Therefore, the present study aimed to reveal the possible mechanism by investigating the effect of okra polysaccharide-2 (RPS-2) on Toll-like receptor (TLR) 2/4-mediated signal transduction pathways in RAW264.7 murine macrophage cells. In order to confirm whether RPS-2 stimulated macrophages activation via TLR2 or TLR4, RAW264.7 murine macrophage cells were pretreated with TLR2/4 inhibitors for 1 h before RPS-2 treatment, and then the NO, IL-10, TNF-α levels were tested. The results indicated that both TLR2 and TLR4 were the keys of immune regulatory effect of RPS-2. Afterwards, the effect of RPS-2 on NF-κB and MAPKs signaling pathways were studied by western blot analysis. It showed RPS-2 induced the phosphorylation of p65, IκBα, p38, ERK1/2 and JNK. At the same time, the specific inhibitors reduced these phosphorylation levels as well as NO, IL-10 and TNF-α amounts. In a word, RPS-2 activated macrophages by NF-κB and MAPKs signal transduction pathways.

Abstract
Biomacromolecules, the first components of bioactive substances in traditional Chinese medicines (TCM) have wide bioactivity-related efficacy but have not yet been fully appreciated compared to small molecule components. The present review brings a novel and systemic point of view to deepen the understanding of the pharmacodynamic material basis of TCM based on biomacromolecules (polysaccharides, proteins and nucleic acids). Biomacromolecules have been, are and will have considerable roles in the efficacy of Chinese medicine, as evidenced by the number of biological activities related to traditional clinical efficacy. The direct and indirect mechanisms of biomacromolecules are further accounted for in a variety of neurotransmitters, hormones, and immune substances to maintain immune function in both sensitive and stable equilibrium. The biological functions of biomacromolecules have been elaborated on in regard to their roles in the process of plant growth and development to the relationship between primary metabolism and secondary metabolism and to the indispensable role of polysaccharides, proteins, and nucleic acids in the quality formation of TCM. Understanding the functional properties and mechanisms of biological macromolecules will help to demystify the drug properties and health benefits of TCM.

Abstract
OBJECTIVE The objective of this study was to explore the effect of Alpiniae oxyphyllae Fructus (AOF) on a rat model of chronic intermittent hypoxia (CIH)-induced enuresis. Findings of this study may help identify therapeutic targets in children with nocturnal enuresis (NE). METHODS Female rats were randomly divided into a control group (saline gavage, 4 weeks of normal air), CIH group (saline gavage, 4 weeks of CIH), and AOF group (AOF gavage, 4 weeks of CIH). The variables measured in this study included water intake, urine output, bladder leak point pressure (BLPP), malondialdehyde (MDA) levels, and superoxide dismutase (SOD) activity. The expression levels of the purinergic P2X3 receptor, muscarinic M3 receptor, and ß3-adrenergic receptor (ß3-AR) in the bladder were also measured. The bladder was subjected to haematoxylin and eosin (HE) and Weigert staining, and histological changes were observed under a light microscope to evaluate the morphological changes in the bladder in each group. RESULTS Compared with the control group, urine output was increased, and the BLPP was decreased in the CIH group, but AOF administration decreased urine output and increased BLPP. In addition, the serum MDA level increased and the SOD activity decreased in the CIH group compared with the control group. Administration of AOF decreased the MDA level and increased the SOD activity. Additionally, compared with the control group, HE and Weigert staining in the CIH group showed that the bladder detrusor muscle bundles were disordered and loose, some muscle bundles were broken, the content of collagen fibres in the gap was reduced, and the gap was significantly widened. However, following the administration of AOF, the bladder detrusor muscle bundles were neatly arranged, and the content of collagen fibres in the gap was increased. Furthermore, compared with the control group, the purinergic P2X3 receptor and muscarinic M3 receptor were expressed at higher levels, and ß3-AR was expressed at lower levels in the CIH group, but AOF administration decreased the expression of the purinergic P2X3 receptor and muscarinic M3 receptor and increased the expression of the ß3-AR. CONCLUSIONS AOF improves enuresis by inhibiting oxidative stress and regulating the expression of the purinergic P2X3 receptor, muscarinic M3 receptor, and ß3 adrenergic receptor.
