Enzyme immobilized on magnetic fluorescent bifunctional nanoparticles for α-glucosidase inhibitors virtual screening from Agrimonia pilosa Ledeb extracts accompanied with molecular modeling. J Chromatogr A 2023; 1711:464433. [PMID: 37847969 DOI: 10.1016/j.chroma.2023.464433] [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: 07/05/2023] [Revised: 10/01/2023] [Accepted: 10/05/2023] [Indexed: 10/19/2023]
Abstract
Agrimonia pilosa Ledeb (APL) is a significant source of inhibitors for α-glucosidase, which is an essential target enzyme for the treatment of type 2 diabetes, cancer and acquired immune deficiency syndrome. Ligand fishing is a suitable approach for the highly selective screening of bioactive substances in complex mixtures. Yet it is unable to conduct biomedical imaging screening, which is crucial for real-time identification. In this case, a bioanalytical platform combining magnetic fluorescent ligand fishing and in-situ imaging technique was established for the screening and identification of α-glucosidase inhibitors (AGIs) from APL crude extract, utilizing α-glucosidase coated CuInS2/ZnS-Fe3O4@SiO2 (AG-CIZSFS) nanocomposites as extracting material and fluorescent tracer. The AG-CIZSFS nanocomposites prepared through solvothermal and crosslinking methods displayed fast magnetic separation, excellent fluorescence performance and high enzyme activity. The tolerance of immobilized enzyme to temperature and pH was stronger than that of free enzyme. Prior to proof-of-concept with APL crude extract, a number essential parameters (glutaraldehyde concentration, immobilized time, enzyme amount, reaction solution pH, incubation temperature, incubation time, percentage of methanol in eluen, elution times and eluent volume) were optimized using an artificial test mixture. The fished ligands were identified by UPLC-MS/MS and their biological activities were preliminarily evaluated by real-time cellular morphological imaging of human colon carcinoma (HCT-116) cells based on confocal laser scanning microscope (CLSM). Their α-glucosidase inhibitory activities were further verified and studied by classical pNPG method and molecular docking. The isolated compounds exhibited significant α-glucosidase inhibitory activities with a IC50 value of 11.57 µg·mL-1. Six potential AGIs including tribuloside, ivorengenin A, tormentic acid, 1β, 2β, 3β, 19α-Tetra hydroxyurs-12-en-28-oic acid, corosolic acid and pomolic acid were ultimately screened out and identified from APL crude extracts. The proposed approach, which combined highly specific screening with in-situ visual imaging, provided a powerful platform for discovering bioactive components from multi-component and multi-target traditional Chinese medicine (TCM).

BMC Complement Med Ther 2023; 23:322.

Abstract
BACKGROUND Researches and practice of traditional Chinese medicine indicated that Agrimonia pilosa Ledeb could improve insulin resistance (IR) and treat type 2 diabetes (T2DM). To reveal its underling mechanisms, we isolated Flavonoid component (FC) from Agrimonia pilosa Ledeb and elucidated its effects on glucose metabolism to improve IR by suppressing oxidative stress and inflammation. METHODS Adipocytes or mice IR model was established with overdosed glucose and insulin or high-fat diet. The uptake of 2-NBDG and glucose consumption were measured to verify insulin sensitivity in vitro and vivo. Reactive oxidative species (ROS) were detected by flow cytometry, and superoxide dismutase (SOD) activity as well as the malondialdehyde (MDA) content were also measured. Meanwhile, factors associated with insulin signal pathway including PPARγ, insulin receptor substrate-1 (IRS-1), GLUT4, and oxidative stress including NF-E2-related factor 2 (Nrf2), as well as the related inflammatory cytokines such as NF-κB, IL-1β, IL-6 and TNF-α were tested. Furthermore, the JNK/PI3K/Akt signal pathway was also explored. RESULTS FC extracted from Agrimonia pilosa Ledeb ameliorated the impaired glucose metabolism significantly. Further study indicated that FC could regulate the insulin signal pathway to improve insulin resistance. Moreover, it could upregulate PPARγ with the similar efficacy as pioglitazone (Piog) straightway. FC also decreased the endogenous ROS and MDA content, increased SOD activity and Nrf2 expression to facilitate oxidative homeostasis. It attenuated expression and secretion of inflammatory cytokines obviously. At last, our results indicated JNK/PI3K/Akt pathway was regulated by FC in adipocytes and adipose tissue. CONCLUSION FC could ameliorate glucose metabolism and improve IR. It exerted these effects by suppressing oxidative stress and inflammation. FC from Agrimonia pilosa Ledeb has a good prospect to be drugs or functional foods for IR and T2DM.

Abstract
Obesity, a metabolic disorder, is becoming a worldwide epidemic that predominantly increases the risk for various diseases including metabolic inflammation, insulin resistance, and cardiovascular diseases. However, the mechanisms that link obesity with other metabolic diseases are not completely understood. In obesity, various inflammatory pathways that cause inflammation in adipose tissue of an obese individual become activated and exacerbate the disease. Obesity-induced low-grade metabolic inflammation perturbates the insulin signaling pathway and leads to insulin resistance. Researchers have identified several pathways that link the impairment of insulin resistance through obesity-induced inflammation like activation of Nuclear factor kappa B (NF-κB), suppressor of cytokine signaling (SOCS) proteins, cJun-N-terminal Kinase (JNK), Wingless-related integration site (Wnt), and Toll-like receptor (TLR) signaling pathways. In this review article, the published studies have been reviewed to identify the potential and influential role of different signaling pathways in the pathogenesis of obesity-induced metabolic inflammation and insulin resistance along with the discussion on potential therapeutic strategies. Therapies targeting these signaling pathways show improvements in metabolic diseases associated with obesity, but require further testing and confirmation through clinical trials.

Abstract
Oral cancer is a malignant neoplasm of oral cavity. It accounts for approximately 5% of all malignant tumors. Approximately 97% of all oral cancers are squamous cell carcinomas, followed by adenocarcinomas, and rarely malignant melanomas. It occurs particularly in males (twice as common in males than in females) of middle age (above 40 years). Agrimonia pilosa Ledeb. has traditionally been known for its effective antitumor activity and is currently used in China for cancer therapy. A. pilosa Ledeb. has been traditionally used for the treatment of abdominal pain, sore throat, headache, blood discharge, parasitic infections, and eczema in Korea and other Asian countries. Most studies on A. pilosa Ledeb. are related to the leaves and a few investigated the roots of the plant. However, detailed mechanisms of antitumor activity of A. pilosa Ledeb. have not been fully elucidated. Furthermore, to date, there have been no reports on the antitumor effect of A. pilosa Ledeb. in oral squamous cells. In this study, we used proteomic technology to observe changes in proteins related to anticancer activity of A. pilosa Ledeb. and identified target proteins among altered proteins to reveal the underlying mechanism of action.

Abstract
BACKGROUND Ovarian cancer is a gynaecological tumour has high incidence and mortality rates. Agrimonolide, isolated from Agrimonia pilosa Ledeb, has multiple biomedical activities, including anticancer activity. PURPOSE Here, we aimed to reveal the function of agrimonolide on ovarian cancer progression. METHODS MTT assay, colony-formation assay, flow cytometry, transwell assay, scratch test, western immunoblotting, reactive oxygen species (ROS) detection, and ferroptosis analysis were performed to reveal the role and underlying mechanisms of agrimonolide in ovarian cancer cell lines (A2780 and SKOV-3). The effects of agrimonolide on the SKOV-3 xenograft model were also studied. RESULTS Agrimonolide dose-dependently inhibited proliferation, migration, and invasion and promoted apoptosis in A2780 and SKOV-3 cells. Agrimonolide induced ferroptosis in tumour cells, evidenced by the increased levels of ROS, total iron, and Fe2+ and downregulation of ferroptosis indicators (SLC7A11 and GPX4). The SwissTargetPrediction and Comparative Toxicogenomics Database predicted SCD1 as a target protein for agrimonolide. Molecular Operating Environment software docked agrimonolide in the SCD1 protein, and the binding energy of interaction was -8.21 kcal/mol. The effects of agrimonolide on proliferation, invasion, and induction of apoptosis and ferroptosis were attenuated by SCD1 overexpression in A2780 and SKOV-3 cells. Additionally, agrimonolide attenuated the tumour growth of ovarian cancer in the SKOV-3 xenograft model and significantly downregulated SCD1 in tumour tissues. CONCLUSION Our study is the first to suggest that agrimonolide acts as a novel apoptosis- and ferroptosis-inducing agent in ovarian cancer cells by targeting SCD1. Agrimonolide may be a novel therapeutic agent for treating ovarian cancer.

Abstract
The global emergence of the COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has focused the entire world’s attention toward searching for a potential remedy for this disease. Thus, we investigated the antiviral activity of Agrimonia pilosa ethanol extract (APEE) against SARS-CoV-2 and it exhibited a potent antiviral activity with IC50 of 1.1 ± 0.03 µg/mL. Its mechanism of action was elucidated, and it exhibited a virucidal activity and an inhibition of viral adsorption. Moreover, it presented an immunomodulatory activity as it decreased the upregulation of gene expression of COX-2, iNOS, IL-6, TNF-α, and NF-κB in lipopolysaccharide (LPS)-induced peripheral blood mononuclear cells. A comprehensive analysis of the phytochemical fingerprint of APEE was conducted using LC-ESI-MS/MS technique for the first time. We detected 81 compounds and most of them belong to the flavonoid and coumarin classes. Interestingly, isoflavonoids, procyanidins, and anthocyanins were detected for the first time in A. pilosa. Moreover, the antioxidant activity was evidenced in DPPH (IC50 62.80 µg/mL) and ABTS (201.49 mg Trolox equivalents (TE)/mg) radical scavenging, FRAP (60.84 mg TE/mg), and ORAC (306.54 mg TE/g) assays. Furthermore, the protective effect of APEE was investigated in Lipopolysaccharides (LPS)-induced acute lung injury (ALI) in mice. Lung W/D ratio, serum IL-6, IL-18, IL-1β, HO-1, Caspase-1, caspase-3, TLR-4 expression, TAC, NO, MPO activity, and histopathological examination of lung tissues were assessed. APEE induced a marked downregulation in all inflammation, oxidative stress, apoptosis markers, and TLR-4 expression. In addition, it alleviated all histopathological abnormalities confirming the beneficial effects of APEE in ALI. Therefore, APEE could be a potential source for therapeutic compounds that could be investigated, in future preclinical and clinical trials, in the treatment of patients with COVID-19.

Female Sprague-Dawley rats were sham-operated or ovariectomized, and 3 weeks later were assigned to the following groups: sham-operated + HFD (S); ovariectomized + HFD (OVX); and ovariectomized + HFD with 0.5% A. pilosa aqueous extract (OVX + 0.5A) groups. Ovariectomy significantly increased body weight and dietary intake relative to the S group. However, A. pilosa treatment did not significantly affect weight gain or dietary intake. Blood triacylglycerol, total cholesterol, and low-density lipoprotein cholesterol levels tended to decrease in the A. pilosa-supplemented group. Blood glucose levels were significantly lower in the OVX + 0.5A group than those in the OVX group. Blood adiponectin and insulin concentrations increased significantly after A. pilosa treatment in the ovariectomized group. A. pilosa supplementation tended to decrease liver weights and prevented lipid accumulation. These effects correlated with reduced hepatic expression of lipogenesis-related genes (fatty acid synthase, acetyl-coenzyme A carboxylase alpha, and 3-hydroxy-3-methylglutaryl-coenzyme A reductase). Therefore, A. pilosa may improve metabolic disorders in ovariectomized rats.

α-Tocopherol Protects the Heart, Muscles, and Testes from Lipid Peroxidation in Growing Male Rats Subjected to Physical Efforts. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:8431057. [PMID: 33927795 PMCID: PMC8051519 DOI: 10.1155/2019/8431057] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Revised: 05/05/2019] [Accepted: 06/27/2019] [Indexed: 12/30/2022]
Abstract
The effect of α-tocopherol supplementation on adaptation to training is still equivocal. The aim of the study was to determine the effect of training and α-tocopherol supplementation on α-tocopherol and thiobarbituric acid reactive substance (TBARS) concentration in the rat liver, heart, muscles, and testes. Male Wistar rats (n = 32) were divided into four groups (nonsupplemented, not trained—C; nonsupplemented, trained—CT; supplemented, not trained—E; supplemented and trained—ET). During the 14-day experimental period, 2 mg/d of vitamin E as α-tocopherol acetate was administered to the animals (groups E and ET). Rats in the training group (CT and ET) were subjected to 15 minutes of treadmill running each day. The α-tocopherol levels in rat tissues were assessed using high-performance liquid chromatography (HPLC). Lipid peroxides were determined by TBARS spectrophotometric method. α-Tocopherol had a significant impact on α-tocopherol concentration in all tissues. Training increased the α-tocopherol concentration in the heart and muscles but reduced it in the liver. Training also caused increased lipid peroxidation in the muscles, heart, and testes; but a higher α-tocopherol content in tissues reduced the TBARS level. The main finding of the study is that impaired α-tocopherol status and its adequate intake is needed to maintain optimal status to prevent damage to the skeletal and cardiac muscles as well as the testes in growing individuals.

Agrimonia procera Wallr. Extract Increases Stress Resistance and Prolongs Life Span in Caenorhabditis elegans via Transcription Factor DAF-16 (FoxO Orthologue). Antioxidants (Basel) 2018; 7:antiox7120192.

Abstract
Agrimonia procera is a pharmacologically interesting plant which is proposed to protect against various diseases due to its high amount of phytochemicals, e.g., polyphenols. However, in spite of the amount of postulated health benefits, studies concerning the mechanistic effects of Agrimonia procera are limited. Using the nematode Caenorhabditis elegans, we were able to show that an ethanol extract of Agrimonia procera herba (eAE) mediates strong antioxidative effects in the nematode: Beside a strong radical-scavenging activity, eAE reduces accumulation of reactive oxygen species (ROS) accumulation and protects against paraquat-induced oxidative stress. The extract does not protect against amyloid-β-mediated toxicity, but efficiently increases the life span (up to 12.7%), as well as the resistance to thermal stress (prolongation of survival up to 22%), of this model organism. Using nematodes deficient in the forkhead box O (FoxO)-orthologue DAF-16, we were able to demonstrate that beneficial effects of eAE on stress resistance and life span were mediated via this transcription factor. We showed antioxidative, stress-reducing, and life-prolonging effects of eAE in vivo and were able to demonstrate a molecular mechanism of this extract. These results may be important for identifying further molecular targets of eAE in humans.

A mouse model of pre-pregnancy maternal obesity combined with offspring exposure to a high-fat diet resulted in cognitive impairment in male offspring. Exp Cell Res 2018; 368:159-166. [PMID: 29698637 DOI: 10.1016/j.yexcr.2018.04.019] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2017] [Revised: 04/16/2018] [Accepted: 04/17/2018] [Indexed: 01/03/2023]
Abstract
BACKGROUND Cognitive impairment is a brain dysfunction characterized by neuropsychological deficits in attention, working memory, and executive function. Maternal obesity and consumption of a high-fat diet (HFD) in the offspring has been suggested to have detrimental consequences for offspring cognitive function through its effect on the hippocampus and prefrontal cortex. Therefore, our study aimed to investigate the effects of maternal obesity and offspring HFD exposure on the brain metabolome of the offspring. METHODS In our pilot study, a LepRdb/+ mouse model was used to model pre-pregnancy maternal obesity and the c57bl/6 wildtype was used as a control group. Offspring were fed either a HFD or a low-fat control diet (LFD) after weaning (between 8 and 10 weeks). The Mirrors water maze was performed between 28 and 30 weeks to measure cognitive function. Fatty acid metabolomic profiles of the prefrontal cortex and hippocampus from the offspring at 30-32 weeks were analyzed using gas chromatography-mass spectrometry. RESULTS The memory of male offspring from obese maternal mice, consuming a HFD post-weaning, was significantly impaired when compared to the control offspring mice. No significant differences were observed in female offspring. In male mice, the fatty acid metabolites in the prefrontal cortex were most affected by maternal obesity, whereas, the fatty acid metabolites in the hippocampus were most affected by the offspring's diet. Hexadecanoic acid and octadecanoic acid were significantly affected in both the hippocampus and pre-frontal cortex, as a result of maternal obesity and a HFD in the offspring. CONCLUSION Our findings suggest that the combination of maternal obesity and HFD in the offspring can result in spatial cognitive deficiency in the male offspring, by influencing the fatty acid metabolite profiles in the prefrontal cortex and hippocampus. Further research is needed to validate the results of our pilot study.

ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2017; 56:219-224. [PMID: 28985617 DOI: 10.1016/j.etap.2017.09.018] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/18/2017] [Revised: 09/24/2017] [Accepted: 09/25/2017] [Indexed: 06/07/2023]
Abstract
This study is to clarify the protective role of α-lipoic acid in high-fat diet-induced cerebral damage mice. The mice were divided into 5 groups: normal control group, high-fat diet (HFD) group, low-dose α-lipoic acid group for prevention, high-dose α-lipoic acid group for prevention, and high-dose α-lipoic acid group for treatment. The groups' weights and blood glucose changes were monitored. We used HE staining to observe morphological changes in the cerebral cortex. The expression levels of the oxidative stress proteins SOD2, catalase, and the inflammatory pathway proteins p-JNK, p-ERK were measured by western blot and immunochemistry. Compared with the control group, the quantity of cortical neurons in the HFD group was decreased, and the samples exhibited retrogression. However, the lipoic acid significantly protected and promoted the cortical neurons survival. Moreover, compared with the HFD group, the expression levels of SOD2 and catalase in the three α-lipoic acid obtained groups were significantly increased. However, the expression levels of the inflammatory pathway proteins p-JNK and p-ERK were significantly decreased. These results indicate that theα-lipoic acid greatly protects the cortical neurons, and inhibited the oxidative stress and inflammatory reactions in the high-fat diet mice.
