Background/PurposeSome health-beneficial foods, including adzuki beans ( Vigna angularis), can show antihyperglycemic effects. Adzuki bean-derived polyphenols, such as (+)-catechin 7- O- β-d-glucopyranoside (C7G) and (+)-epicatechin 7- O- β-d-glucopyranoside (E7G), could be potential inhibitors of α-amylase and α-glucosidase, however, few studies of the activity of adzuki polyphenols have been performed in vivo. Thus, we evaluated the antihyperglycemic effects of crude adzuki bean extract containing polyphenols (ABP), and purified C7G or E7G using mice and Caco-2 cells.MethodsSix-week-old male ICR mice were orally administered ABP (100 or 250 mg/kg), C7G or E7G (15 or 40 mg/kg), and sucrose (2 g/kg). Blood samples were taken from the lateral tail vein to measure the blood glucose levels at various times over 0–120 min. Cultured caco-2 cells, an intestinal model, were treated with ABP, C7G, or E7G. The glucose concentration in the medium was measured to examine the activity of α-glucosidase.ResultsAdministration of adzuki polyphenols decreased blood glucose levels, especially E7G administration significantly showed antihyperglycemic effects in vivo. In Caco-2 cells, α-glucosidase activity was significantly decreased by ABP, C7G, or E7G addition in a dose-dependent manner without cytotoxicity.ConclusionThese results suggest that C7G and E7G in adzuki bean extract inhibited sucrose-degrading enzymes to elicit antihyperglycemic effects in vivo, which supports the results of previous studies using adzuki beans, and may contribute to health promotion.

Objective: Parkinson's disease (PD) is a neurodegenerative disease characterized by the loss of dopaminergic neurons and persistent neuroinflammation in the substantia nigra (SN), triggering a dopamine deficiency that can lead to movement disorders. Neuroinflammation is a common feature of aging brains and neurodegenerative diseases. Inflammasome-related neuroinflammation is involved in the progression of PD. Methods: The effects of cimifugin was investigated in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mouse model of PD. Cimifugin is one of the main components of Saposhnikovia divaricata (Turcz.) Schischkin. Behavioral tests, such as the rotarod, pole, and traction tests, were conducted to measure the recovery effects of Parkinson-related motor deficiencies. Results: Our analyses showed that cimifugin treatment mitigates motor dysfunction in a dose-dependent manner. In addition, cimifugin conferred neuroprotection by increasing the survival of dopaminergic neurons, as measured by tyrosine hydroxylase immunostaining. Neuroinflammation was reduced by cimifugin by inhibiting NLR family pyrin domain-containing 3 (NLRP3)/caspase-1/interleukin 1β signaling in the MPTP-insulted SN. Moreover, monosodium urate crystals, an NLRP3 agonist, reversed cimifugin-induced improvement in motor function in the PD model. Conclusion: These results suggest that cimifugin administration is a potential therapeutic strategy for mitigating PD.

Objective: Shengjiang Powder (SJP) is a traditional Chinese medicine compound formula commonly used in the treatment of diabetic kidney disease (DKD). However, its material basis and mechanism of action are still unclear. Methods: In this study, the aqueous extract of SJP was obtained by aqueous decoction method, and the in vivo and in vitro constituents of SJP were analysed by ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS), and a network pharmacological strategy was established in conjunction with molecular docking in order to investigate the mechanism of action of SJP in the treatment of DKD. Results: The results identified 162 components, of which 28 could be absorbed into the blood and exert therapeutic effects in vivo. The main active ingredients were CT-1, CT-2, CT-7, BJC-2, and BJC-5, and the main targets in vivo were related to AKT1, MAPK1, MAPK3, MAPK8, and MAPK14, which could exert their therapeutic effects through the PI3K-Akt signaling pathway, Insulin resistance, and AGE-RAGE signaling pathway in diabetic complications, etc Conclusion: The present study adopts a comprehensive analytical strategy to reveal the pharmacodynamic material basis and mechanism of action of SJP in the treatment of DKD, and to provide a scientific basis for its clinical application.

ObjectiveThe objective of our study was to investigate the chemical composition and the biological activities of different parts of Securidaca longipedunculata from South Africa.MethodologiesThe chemical analysis methods, including chromatography and spectroscopy, were employed to identify the diverse array of compounds present in the roots, leaves, and stems of S longipedunculata.ResultsThe proximate analysis revealed that the leaf extracts had higher ( P < .05) crude protein, gross energy, and ether extract contents when compared to the stem bark and the root bark. A similar trend was observed with the mineral analysis where copper, iron, magnesium, and zinc were in abundance in the leaves. Concurrently, bioassays reveal significant biological activities, such as antioxidant, antimicrobial, and anti-inflammatory properties, associated with these plant parts. The extracts demonstrated high lipid peroxidation inhibitory activity at the concentration of 250 μg/mL, with the highest percentage inhibition of 94% recorded in the dark leaf extract, followed by 92% and 73% at the concentrations of 125 and 62.5 μg/mL, respectively. The antimicrobial analysis revealed that the root bark extract was active against Escherichia coli, Pseudomonas aeruginosa, and Enterococcus faecalis with the average minimum inhibitory concentration of 1.67 mg/mL (dark type) and 0.63 mg/mL (light type).ConclusionOur findings emphasize the medicinal potential of S longipedunculata and underscore the importance of understanding its chemical makeup in explaining its therapeutic effects. This research provides valuable insights into the pharmacological properties of S longipedunculata, offering a foundation for further exploration in drug development and natural product discovery.

Some plants used in traditional medicine to manage sickle cell disease have been validated pharmacologically to ascertain their anti-sickling properties. However, there is no global systematic review of the evidence in support of their use for sickle cell management. This research aimed to conduct a systematic review of the pharmacological evidence to highlight species, genera, and some phytochemicals which could be primed for novel anti-sickling medications. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were used. Articles in English, published from 2000 to 2022 were included in the analysis. The literature search covered 411 publications of which 82 were found to be eligible. More than half (53.65%) of the articles were published from 2016 to 2022. Anti-sickling research from Africa accounted for 86.58% of the publications, with more than half coming from Nigeria, 12.20% from Asia and only 1.22% from Europe. The Fabaceae, Euphorbiaceae, and Annonaceae were the top three plant families whereas Zanthoxylum and Terminalia were the most reported genera. Carica papaya and Terminalia catappa were the most reported species. Sickling reversal ( n = 33/82) and hemoglobin polymerization studies ( n = 29/82) were the most reported assays. Benzoic acid derivatives, butyl stearate, ellagic acid derivatives, and some pentacyclic triterpenoids were the only plant derived compounds validated for anti-sickling activities. A total of 117 plant species with anti-sickling activities were documented. Studies on secondary metabolites with anti-sickling properties to serve as scaffolds for novel drug development for sickle cell management were limited.

Objective: The objective was to determine the in vitro antibacterial effect of the Oregano essential oil (OEO) on Streptococcus mutans ( S mutans) and to explore the anti-biofilm effect and mechanism of OEO. Methods: The in vitro antibacterial susceptibility of OEO was detected by the growth curve and colony-forming unit (CFU) counting method. Confocal laser scanning microscope (CLSM) and crystal violet assay were used to explore the anti-biofilm activity of OEO, and the anti-biofilm mechanism was explored from the aspects of extracellular polysaccharides (EPS) synthesis, acidoid, and extracellular DNA changes. OEO was characterized using a gas chromatography-mass spectrometer and cytotoxicity was tested using a cell counting Kit-8 assay. Results: The minimum inhibitory concentration of OEO was 0.25 mg/mL, and the CFU showed the ability of OEO to kill planktonic bacteria. Scanning electron microscopy and CLSM showed that OEO could hinder the development of biofilms, harm bacteria, and eliminate mature biofilms by changing EPS synthesis and pH value. Carvacrol in OEO played a major role in biological antibacterial activity. OEO had low cytotoxicity and good biocompatibility. Conclusions: OEO had excellent antibacterial and anti-biofilm effects on the key virulence traits of S mutans, indicating potential prospects in preventing dental caries.

ObjectivesThe herbal product corilagin is renowned for its liver-protecting benefits and antioxidant properties. However, the protective role of corilagin in alcoholic liver injury remains unexplored. The objective of this study is to delve into the protective effects of corilagin on alcoholic liver injury, both in HepG2 cells and a mouse model.MethodsTo assess the antioxidant capacity of corilagin in vitro, DPPH and ABTS assays were conducted. HepG2 cells were pretreated with 800 mM ethanol for 24 hours, followed by corilagin treatment for another 24 hours, to evaluate its liver-protecting activity. For in vivo studies, ICR mice, with and without corilagin treatment, were given ethanol for 4 weeks to induce alcoholic liver injury. At the end of the study, serum and liver tissue samples were collected to analyze liver function, enzymatic antioxidants, reactive oxygen species (ROS) levels, alcohol dehydrogenase, and liver tissue histology.ResultsThe findings reveal that corilagin exhibits remarkable free radical scavenging ability and alleviates alcohol-induced cell damage in vitro. In vivo, corilagin significantly reduced liver index and serum levels of aminotransferase aspartate, alanine transaminase, total cholesterol, and triglyceride in mice with alcoholic liver injury. Additionally, corilagin decreased ROS levels in liver tissue and increased the activities of antioxidant enzymes CAT, SOD, and GSH-Px. GSH content increased, while lipid peroxide MDA decreased in liver tissue.ConclusionOur data strongly suggests that corilagin possesses protective effects on alcoholic liver injury, both in vitro and in vivo, which is likely attributed to its exceptional antioxidant capacity. In summary, corilagin holds promise as a potential preventive or therapeutic agent for alcoholic liver injury.

However, the protective role of corilagin in alcoholic liver injury remains unexplored. The objective of this study is to delve into the protective effects of corilagin on alcoholic liver injury, both in HepG2 cells and a mouse model.MethodsTo assess the antioxidant capacity of corilagin in vitro, DPPH and ABTS assays were conducted. HepG2 cells were pretreated with 800 mM ethanol for 24 hours, followed by corilagin treatment for another 24 hours, to evaluate its liver-protecting activity. For in vivo studies, ICR mice, with and without corilagin treatment, were given ethanol for 4 weeks to induce alcoholic liver injury. At the end of the study, serum and liver tissue samples were collected to analyze liver function, enzymatic antioxidants, reactive oxygen species (ROS) levels, alcohol dehydrogenase, and liver tissue histology.ResultsThe findings reveal that corilagin exhibits remarkable free radical scavenging ability and alleviates alcohol-induced cell damage in vitro. In vivo, corilagin significantly reduced liver index and serum levels of aminotransferase aspartate, alanine transaminase, total cholesterol, and triglyceride in mice with alcoholic liver injury. Additionally, corilagin decreased ROS levels in liver tissue and increased the activities of antioxidant enzymes CAT, SOD, and GSH-Px. GSH content increased, while lipid peroxide MDA decreased in liver tissue.ConclusionOur data strongly suggests that corilagin possesses protective effects on alcoholic liver injury, both in vitro and in vivo, which is likely attributed to its exceptional antioxidant capacity. In summary, corilagin holds promise as a potential preventive or therapeutic agent for alcoholic liver injury.","PeriodicalId":19019,"journal":{"name":"Natural Product Communications","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ObjectivesThe genus Glochidion (the family Phyllanthaceae) is used for various medicinal purposes, such as dysentery, diarrhea, cough, and skin protection. A review of phytochemical and pharmacological aspects for this remains unavailable. The current study tends to sum up a detailed list of phytochemicals, and their role in biological examinations.MethodsReferences in English were obtained by an extensive search across various electronic data sources, encompassing Web of Science, PubMed, Google Scholar, and Science Direct. The “Sci-Finder” was also utilized to find references and revise chemical structures. Referenced documents have been gathered from the 1960s to date. It also noted that Glochidion, phytochemistry, and pharmacology are likely the keywords to seek for references.ResultsOver 240 naturally occurring phytochemicals were isolated and identified from various Glochidion tissues, including terpenoids, sterols, saponins, lignans, flavonoids, mono-phenols, megastigmanes, butenolides, glycosides, alkaloids, cyanogens, tocopherols, fatty acids, and others. Three naturally occurring triterpenoids glochidonol, glochidiol, and glochidone are the likely characteristic metabolites, being isolated frequently. Glochidion crude extracts and their isolated compounds have been demonstrated as potential agents in various pharmacological targets, such as cytotoxicity, antioxidant, antiinflammation, and neuron and liver protection.ConclusionSeveral isolates acted as promising agents in pharmacological assays. The anticancer mechanisms of various triterpenoids and saponins, especially new and potential compounds, are expected. Pharmacological advancements to enhance the efficacies of Glochidion constituents, such as synergistic combinations and nano-drug formulations, are encouraged.
