Antinociceptive, anti-inflammatory, and antioxidant effects of a flavonoid-rich phytocomplex from the leaves of Celtis iguanaea (jacq.) Sargent (Cannabaceae). Nat Prod Res 2024:1-11. [PMID: 39262209 DOI: 10.1080/14786419.2024.2401501] [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: 02/20/2024] [Revised: 08/01/2024] [Accepted: 09/02/2024] [Indexed: 09/13/2024]
Abstract
We demonstrated the antinociceptive and anti-inflammatory effects of the ethyl acetate leaf extract of Celtis iguanaea (Jacq.) Sargent (EAECi) in mice. The in vitro antioxidant activity of EAECi and its phytoconstituents was also investigated. The antinociceptive effect of EAECi is attributed to its anti-inflammatory activity, as evidenced by its anti-hyperalgesic and antiedematogenic effects. EAECi reduced polymorphonuclear cell migration, myeloperoxidase activity, pro-inflammatory cytokines (TNF-α and IL-1β), and PGE2 levels. The levels of anti-inflammatory cytokines (IL-4 and IL-10) were increased compared to the vehicle-treated groups. The overall antioxidant capacity of EAECi is noteworthy, with the Electrochemical Index determined by Differential Pulse Voltammetry being 42.7 μA/V. Concurrently, Square Wave Voltammetry revealed the reversibility of the redox process (Ep1a/Ep1c) at 0.254 V. The presence of twenty-six phytochemicals, primarily flavone aglycones, was suggested by paper-spray mass spectrometry. These findings represent a step towards validating C. iguanaea leaf extract for treating acute inflammatory conditions.

Abstract
The plants of Celtis L. genus have been traditionally used to cure aches, sore throats, fevers, cancer, sexually transmitted diseases, sexual weakness, diarrhea, stomach problems, amenorrhea, menstrual disorders, kidney stones, and pain. The review aims to give a comprehensive account of the current state of ethnopharmacology, phytochemistry, and biological activities of the Celtis genus, as well as to describe the potential area of future avenues. Information on the Celtis genus was obtained from internet sources such as Google Scholar, Web of Science, PubMed, ScienceDirect, and so on by using appropriate keywords, including ethnobotanical, pharmacological, pharmaceutical, bioactivity, phytochemistry, and botanical features of the Celtis genus. This review identified 14 species in the genus Celtis that have a phytopharmacological investigation, including C.africana Burm. f., C. australis L., C. occidentalis L., C. sinensis Pers., C. philippensis Blanco., C. tetrandra Roxb., C. tessmannii Rendle., C. jessoensis Koidz., C. adolfi-friderici Engl., C. iguanaea (Jacq.) Sarg., C. laevigata Wild., C. pallida Torr., C. zenkeri Engl., and C. tournefortii Lam. This genus contains many classified phytoconstituents, such as terpenoids, organic acids, flavonoids, and volatile compounds. Their extracts and pure substances have been shown to have the same anticancer, antibacterial, anti-inflammatory, antioxidant, hepatoprotective, cardioprotective, urease-inhibiting, and antidiarrheal properties as their traditional uses. In terms of current information on ethnopharmacology, phytochemicals, and pharmacological uses, the data acquired in this review could be beneficial and needed for future research. Some phytoconstituents (for instance, kaempferol, myricetin, quercetin, and eugenol) and extracts (for example, leaves, seeds, and ripe fruits extracts of C. australis) showed tremendous results in preliminary testing with promising antimicrobial, anticancer, and urease inhibitory effects. Further research and clinical investigations are needed to develop them as lead compounds and neutraceuticals, which may provide an advance over traditional medicinal systems.

Abstract
Introduction: Fast food is a major risk factor for atherosclerosis, a leading cause of morbidity and mortality in the Western world. Apelin, the endogenous adipokine, can protect against cardiovascular disease via activating its receptor, APJ. Concurrently, secoisolariciresinol diglucoside (SDG), a flaxseed lignan extract (FLE), showed a therapeutic impact on atherosclerosis. The current study aimed to examine the effect of SDG on cafeteria diet (CAFD)-induced vascular injury and cardiac fibrosis via tracking the involvement of the apelin/APJ pathway. Methods: Thirty male rats were allocated into control, FLE-, CAFD-, CAFD/FLE-, and CAFD/FLE/F13A-treated rats, where F13A is an APJ blocker. All treatments lasted for 12 weeks. Results and discussion: The CAFD-induced cardiovascular injury was evidenced by histological distortions, dyslipidemia, elevated atherogenic indices, cardiac troponin I, collagen percentage, glycogen content, and apoptotic markers. CAFD increased both the gene and protein expression levels of cardiac APJ, apelin, and FOXO3a, in addition to increasing endothelin-1, VCAM1, and plasminogen activator inhibitor-1 serum levels and upregulating cardiac MMP-9 gene expression. Moreover, CAFD reduced serum paraoxonase 1 and nitric oxide levels, cardiac AMPK, and nuclear Nrf2 expression. FLE attenuated CAFD-induced cardiovascular injury. Such effect was reduced in rats receiving the APJ blocker, implicating the involvement of apelin/APJ in FLE protective mechanisms. Conclusion: FLE supplementation abrogated CAFD-induced cardiac injury and endothelial dysfunction in an apelin/APJ-dependent manner.

Characterization of the chemical profile and the effects of ethanolic extracts of Maytenus ilicifolia Mart. ex Reissek on glucose metabolism in normal hyperglycemic rats. JOURNAL OF ETHNOPHARMACOLOGY 2021; 276:114173. [PMID: 33932519 DOI: 10.1016/j.jep.2021.114173] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 04/23/2021] [Accepted: 04/25/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Maytenus ilicifolia Mart. ex Reissek, Celastraceae, is popularly known as "espinheira-santa" and used to treat pathologies related to the stomach. However, in popular culture, this species has also been used to treat other disorders such as diabetes, but without scientific evidence, requiring more phytochemical and pharmacological studies on the plant. AIM OF THE STUDY This work aims to investigate the anti-hyperglycemic potential of ethanolic extracts obtained from leaves from two different accessions of Maytenus ilicifolia (MIA and MIB) in normal hyperglycemic rats. MATERIALS AND METHODS The animals were divided into different experimental groups: normal hyperglycemic (negative control); MIA (treatment of Maytenus ilicifolia extract from access 116); MIB (treatment with Maytenus ilicifolia extract from access 122; and glipizide (positive control). At 30 min after treatment, all animals received glucose overload orally. Blood collection occurred at different periods for the assessment of blood glucose (0, 60, 90 and 210 min after treatment) and at the end of the experiment blood was collected through cardiac puncture and the liver, muscle, pancreas and intestine were dissected for further analysis. RESULTS Chromatographic analysis identified oleic and palmitic acid as the most common constituents, and both extracts of Maytenus ilicifolia caused a reduction in blood glucose levels within 60 min after administration of glucose overload when compared to the normal hyperglycemic group. No significant changes were observed in hepatic and muscular glycogen levels, plasma insulin concentration and disaccharidases activity with none of the extracts in the model employed. However, hyperglycemic rats treated with the extracts showed a marked increase in triglyceride and HDL cholesterol levels. CONCLUSIONS Our data suggest that Maytenus ilicifolia extracts from different locations showed differences in chemical composition which did not reflect significant differences in the results of biological tests. In addition, it was possible to conclude that the treatment with Maytenus ilicifolia had a discreet anti-hyperglycemic effect; however, it was not possible to identify the responsible mechanism, being necessary, therefore, new studies using different technologies in order to determine the possible mechanisms of action of the extract.

Abstract
This study aimed to investigate the antioxidant and hepatoprotective effects of Celtis tournefortii fruit extract (Ct) against copper-induced liver damage in rats. Thirty-two Wistar Albino rats were divided into four equal groups (n = 8): Control, Copper (Cu), Copper + C. tournefortii (Cu+Ct), and C. tournefortii (Ct). Superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) activities, glutathione (GSH) concentration, malondialdehyde (MDA), total antioxidant status (TAS) and total oxidant status (TOS) were analysed in the liver tissues. Liver histopathology was also evaluated. Alanine aminotransferase and lactate dehydrogenase significantly decreased in the Cu+Ct group compared with the Cu group. Oxidative stress parameters MDA and TOS significantly increased with copper administration, whereas they decreased with C. tournefortii co-treatment compared to Cu group. GSH concentration and TAS showed significant decreases with copper administration. Celtis tournefortii co-supplementation with copper significantly enhanced antioxidant parameters such as TAS, SOD, and GPx. Celtis tournefortii remarkably attenuated degenerative and necrotic changes caused by the oral exposure of copper in the liver tissue of rats. Celtis tournefortii may provide amelioration of the antioxidant status and moderation of severity of liver damage against copper toxicity. The therapeutic use of C. tournefortii may exhibit protective effects in liver injury treatment.

Abstract
Ginkgo acids (GAs) in ginkgo products usually lead to allergies or liver toxicity. In this study, the GA-induced toxicity was attenuated and Con A-induced T-lymphocyte proliferation was inhibited by extracts of Celtis sinensis leaves (ECSL). So, the active ingredients in ECSL were studied to solve the problems caused by GAs. First, the eight components of MeOH extracts were determined by HPLC-DAD/LC-MS. Then, the 12 active ingredients were separated based on the anti-inflammatory activity. Lymphocyte conversion showed that the inhibition rates of apigenin, quercetin, and isovitexin at 100 μM on Con A-activated proliferation of T cells were up to 82.46%, 62.86% and 42.76%, respectively. The inhibition rate on the LPS-induced NO release in RAW 264.7 cells of quercetin, apigenin, isovitexin, and vitexin were exceeding 80% at 100 μM. Taken together, the material foundation for the screen of GAs toxicity-attenuated ingredients were provided here. PRACTICAL APPLICATIONS: Ginkgo biloba extracts (EGBs) have been conducted to develop functional food which could increase blood circulation and enhance memory. Nevertheless, people in consumption of ginkgo products, often caused severe allergic reactions due to the potential allergens identified ginkgolic acids (GAs) of ginkgo products. We first find that the extracts of Celtis sinensis leaves can reduce GAs-induced damage on HepG2 liver cells. Then, the bioactive compounds in C. sinensis leaves were separated and purified based on anti-inflammatory activities against T cells. Quercetin, apigenin, and isovitexin showed well anti-inflammatory activities against Con A-activated T-lymphocytes and LPS activated RAW 264.7 macrophages. However, quercetin and apigenin are flavones O-glycosides which are rich in Ginkgo biloba. To solve the problems in Ginkgo biloba products caused by GAs, flavone C-glycoside (isovitexin) may be used for the further study in GAs toxicity-reduction.

Abstract
Exposure to contaminants is one of the main threats to all living organisms. In this context, bats have been used to indicate environmental contaminants in urban and agricultural environments, since they are extremely sensitive to changes in the ecosystem and easily accumulate waste in their body tissues. Among bats, Sturnira lilium, is a frugivorous species widely distributed and abundant in Brazil that uses an extensive variety of habitats and shelters. In this study, we aimed to evaluate the oxidative state of S. lilium individuals in agricultural and urban areas in southern Brazil. Individuals were sampled in agricultural and urban areas from November 2017 to March 2018 through the mist-net method. Parameters of the superoxide dismutase (SOD) and catalase (CAT) enzyme activity, non-protein thiols (NPSH), and lipid peroxidation (TBARS) were determined based on liver tissue. A total of 46 individuals were captured, 29 of them in urban areas and 17 in agricultural areas. We found that S. lilium individuals from agricultural areas showed a significant increase in TBARS, NPSH, and SOD activity, compared to individuals from urban areas. The activity of the antioxidant enzyme CAT did not differ. The present findings suggest that the species S. lilium, which are widely distributed and abundant in Brazil in urban and agricultural areas, can usefully be employed in biomonitoring programs. Further studies are to be encouraged to refine our knowledge on the potential DNA damage caused by environmental contamination, as well as identify potential contaminants to bats.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pilosocereus gounellei is a plant found in the Brazilian Caatinga and is popular due to its traditional uses in the treatment of inflammation. The present study was conducted to investigate the sub-acute toxicity of the saline extract from the stem of P. gounellei. AIM OF THE STUDY To evaluate the 28-day oral toxicity (through behavioral, biochemical, hematological, and morphological analysis) and the antipyretic activity of the extract in mice. MATERIALS AND METHODS A single oral dose (250, 500, and 1000 mg/kg) was administered daily over 28 consecutive days to male and female mice. Body weight, food and water intake, blood biochemical and hematological parameters, and urine composition were recorded. Histopathological examinations of the liver, kidney, spleen, lungs, and heart were performed and oxidative stress in the organs was evaluated by lipid peroxidation, superoxide dismutase (SOD), catalase (CAT), and nitrite analysis. The antipyretic effect of the 500 mg/kg dose was assessed using a yeast-induced pyrexia model. RESULTS Oral administration of the extract over 28 days did not affect body weight gain, food and water consumption, body temperature, and hematological parameters in male and female mice. Blood glucose, total cholesterol, and triglyceride levels in male and female mice were reduced. Protein in the urine and histological alterations in both the liver and lungs were detected in male and female mice treated with the highest dose of the extract. SOD levels in the liver and the spleen increased significantly in both sexes, whereas lipid peroxidation decreased in the spleen of male mice. The extract also exerted an antipyretic effect after the first 60 min of the evaluation until the end of the observation duration (180 min). CONCLUSION The saline extract from the stem of P. gounellei did not present significant toxic effects over 28 consecutive days and demonstrated antipyretic activity when administered orally. Moreover, the results suggest that the extract has potential hypoglycemic and hypolipidemic effects. Future studies are needed to investigate its pharmacological potential.
