Rob. initiates caspase 3-dependant apoptosis in colorectal cancer cell: A synergistic approach with chemotherapeutic drugs. JOURNAL OF ETHNOPHARMACOLOGY 2024; 322:117591. [PMID: 38104872 DOI: 10.1016/j.jep.2023.117591] [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: 09/29/2023] [Revised: 11/28/2023] [Accepted: 12/11/2023] [Indexed: 12/19/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ageratina adenophora (Sprengel) R.M.King & H.Rob. has been used as traditional indigenous medicine all across the globe for its diverse therapeutic applications such as anticancer, analgesic, antipyretic, thermogenic, antiseptic, antimicrobial as well as astringent. The various ethnic groups of India use plant parts to treat cuts and wounds, venomous insect bites, skin lesions, blisters, scabies and other skin irritations, gastritis and indigestion problems, cough, stomach ache and dysentery. The Portuguese traditionally extract the juice from the plant and use it for cancer, diabetes, liver disorder, gallbladder and stomach ailments. Nigerian healers use different parts of the plant to treat diabetes, fever and inflammation. AIM OF THE STUDY The aim of this study is to investigate the cytotoxic potential of A. adenophora hydroalcoholic leaves extract (AHL) on Colorectal cancer (CRC) cell lines (HCT-116, HCT-15 and HT-29), synergistic potential with chemotherapeutic drugs 5FU and Cisplatin as well as reactive oxygen species (ROS) generation, based on the sample collected from Mao district of Manipur, India. Identification of bioactive phytocompounds in AHL was also performed by HRLCMS. METHODS The AHL was evaluated for its cytotoxic as well as antiproliferative activities by 3-(4, 5-dimethylthiazol-2-yl)-2, 5 diphenyltetrazolium bromide (MTT) assay, clonogenic and cell migration assays. The total phenolic content (TPC) and total flavonoid content (TFC) were quantified by Folin-ciocalteu and Aluminium chloride assays respectively. Caspase 3 activation was evaluated using Caspase-3 Assay Kit. Apoptosis detection by flow cytometry was carried out using annexin V-FITC/PI apoptosis detection kit. The apoptotic cells were also visualized by Giemsa and 4',6-Diamidino-2-phenylindole (DAPI) staining. The intracellular Reactive oxygen species (ROS) generation was also evaluated using fluorescent probe 2',7'-dichlorodihydrofluorescein di-acetate (H2DCFDA) in flow cytometry. The combination effects of AHL with chemotherapeutic drugs 5FU and Cisplatin were also evaluated. The identification of phytochemical constituents of AHL were analysed by HR-LCMS. RESULTS The AHL induced cytotoxic activity significantly in HCT-116 with IC50 of 65.65 ± 2.10 μg/mL, but non-cancerous cell HeK-293 was least cytotoxic. Colony formation and cell migration were inhibited in a dose and time dependent manner. The cell morphology upon AHL treatment was significantly altered with apoptotic features. The extract was rich in total phenolic (82.09 ± 0.35mgGAE/g) and total flavonoid (58.31 ± 0.55 mgQAE/g) contents. AHL induced apoptosis as detected by AnnexinV/PI, via activation of caspase 3 and elevated production of Reactive oxygen species (ROS). AHL in combination with 5FU and Cisplatin acts synergistically and potentiates the therapeutic properties of the extract. Sesquiterpenes, phenolic as well as flavonoid derivatives with anticancer properties were detected in AHL by HRLCMS, and these phytoconstituents may be attributed for anticancer property of AHL. CONCLUSION The present study evaluates the effectiveness of AHL against Colorectal cancer cell lines. AHL is cytotoxic and induces apoptosis in HCT-116 cells by caspase 3 activation and increased ROS production that can be attributed to sesquiterpenoids. Thus, the plant A. adenophora has therapeutic potential for Colorectal cancer and can be further exploited for developing anticancer drug.

Monitoring the distribution pattern and invasion status of Ageratina adenophora across elevational gradients in Sikkim Himalaya, India. ENVIRONMENTAL MONITORING AND ASSESSMENT 2022; 195:152. [PMID: 36435881 DOI: 10.1007/s10661-022-10549-z] [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: 05/05/2022] [Accepted: 09/10/2022] [Indexed: 06/16/2023]
Abstract
Understanding the spread intensity and population dynamics of invasive plant species is a prerequisite for developing management strategies in the Himalayan Forest ecosystems that are experiencing an accelerated rate of climate change. Although there are studies on the occurrence of few invasive species in the Himalayan ecosystems, systematic information on their intensity of spread and species association is still missing. Considering existing data gaps, we aimed to assess the intensity of spread and distribution pattern of A. adenophora, one of the high-concern invasive species (HiCIS) of India that is causing havoc in the Himalayas, across an elevational gradient. Field data were collected in 2018 and 2021 in the Indian federal state of Sikkim, located in the Eastern Himalayas. We analyzed the population status and species association of A. adenophora along an elevational gradient ranging from > 600 m to 2700 m above sea level, which was divided into seven gradients of 300 m width, and each gradient was further randomly sampled. Overall, 81 species were present in association with A. adenophora, including 58 herbs, 19 shrubs, and 4 climbers, belonging to 30 families and 67 genera in the region. No other species continuously co-occurred along with A. adenophora throughout the elevation ranging from > 600 m to 2700 m. The species observed increased frequency (100%), density (40.51 ind./100 m2), and basal cover (11.25 cm2/m2) in the elevational gradient 1500-1800 m in 2018. In 2021, A. adenophora dominated the highest elevational gradient (< 2400-2700 m) with increased frequency (99.96%), density (58.41 ind./100m2), and basal cover (42.54 cm2/100m2), which demonstrated rapid invasion and improved plant health and reproductive vigor in comparison to the lower elevational gradient in Sikkim Himalaya. Despite being completely absent at the highest elevation (< 2400-2700 m), in 2018, it observed gregarious spread at the highest elevation in 2021, which is of serious concern to ecologists. The presence of the targeted species in all seven studied altitudinal gradients reflects stage III of the species invasion. An enormous shift in the distribution pattern along elevational gradients within a short time span is alarming for the Himalayan ecosystem since it is becoming a thriving habitat for invasive species owing to anthropogenic activity. We mapped the potential geographical extent using the species distribution model (SDM) and predicted the suitable habitat of distribution in Sikkim Himalaya. In order to curtail the spread and counteract the negative impact of this species on native vegetation in Sikkim Himalaya and ultimately reverse the process, local and regional initiatives for its biological control and management must be taken.

Abstract
Ageratina adenophora is one of the major invasive weeds that causes instability of the ecosystem. Research has reported that A. adenophora produces allelochemicals that inhibit the growth and development of food crops, and also contain some toxic compounds that cause toxicity to animals that consume it. Over the past decades, studies on the identification of major toxic compounds of A. adenophora and their toxic molecular mechanisms have been reported. In addition, weed control interventions, such as herbicides application, was employed to reduce the spread of A. adenophora. However, the development of therapeutic and prophylactic measures to treat the various A. adenophora-induced toxicities, such as hepatotoxicity, splenotoxicity and other related disorders, have not been established to date. The main toxic pathogenesis of A. adenophora is oxidative stress and inflammation. However, numerous studies have verified that some extracts and secondary metabolites isolated from A. adenophora possess anti-oxidation and anti-inflammation activities, which implies that these extracts can relieve toxicity and aid in the development of drug or feed supplements to treat poisoning-related disorders caused by A. adenophora. Furthermore, beneficial bacteria isolated from rumen microbes and A. adenophora can degrade major toxic compounds in A. adenophora so as to be developed into microbial feed additives to help ameliorate toxicity mediated by A. adenophora. This review presents an overview of the toxic mechanisms of A. adenophora, provides possible therapeutic strategies that are available to mitigate the toxicity of A. adenophora and introduces relevant information on identifying novel prophylactic and therapeutic measures against A. adenophora-induced toxicity.

Abstract
Eupatorium adenophorum is a malignant invasive plant possessing extraordinary defense potency, but its chemical weaponry and formation mechanism have not yet been extensively investigated. We identified six cadinene sesquiterpenes, including two volatiles (amorpha-4,7(11)-diene and (-)-amorph-4-en-7-ol) and four nonvolatiles (9-oxo-10,11-dehydroageraphorone, muurol-4-en-3,8-dione, 9-oxo-ageraphorone and 9β-hydroxy-ageraphorone), as the major constitutive and inducible chemicals of E. adenophorum. All cadinenes showed potent antifeedant activity against a generalist insect Spodoptera exigua, indicating that they have significant defensive roles. We cloned and functionally characterized a sesquiterpene synthase from E. adenophorum (EaTPS1), catalyzing the conversion of farnesyl diphosphate to amorpha-4,7(11)-diene and (-)-amorph-4-en-7-ol, which were purified from engineered Escherichia coli and identified by extensive nuclear magnetic resonance (NMR) spectroscopy. EaTPS1 was highly expressed in the aboveground organs, which was congruent with the dominant distribution of cadinenes, suggesting that EaTPS1 is likely involved in cadinene biosynthesis. Mechanical wounding and methyl jasmonate negatively regulated EaTPS1 expression but caused the release of amorpha-4,7(11)-diene and (-)-amorph-4-en-7-ol. Nicotiana benthamiana transiently expressing EaTPS1 also produced amorpha-4,7(11)-diene and (-)-amorph-4-en-7-ol, and showed enhanced defense function. The findings presented here uncover the role and formation of the chemical defense mechanism of E. adenophorum - which probably contributes to the invasive success of this plant - and provide a tool for manipulating the biosynthesis of biologically active cadinene natural products.

Abstract
Background: Species belonging to the Asteraceae family have been widely studied for their healing properties. The paper introduces STOMAPET (patent pending A2016/00888/23.11.2016) based on Eupatorium cannabinum (hemp-agrimony) and Inula helenium (elecampagne) and its potential application in diseases of the oral system. Methods: STOMAPET was prepared according to the patent application and HPLC analysis was performed for chemical analysis. In vitro studies were performed using human monocytes and the cells’ viability was determined by MTS assay. In vivo studies involved lipopolysaccharide (LPS)-induced murine endotoxemia and veterinary clinical case reports. Results: HPLC analysis revealed various phenolic compounds and alantolactone. In in vitro studies, monocytes viability remained stable, around and above 100% at all concentrations (7.8 to 250 µg/mL), and a high stimulatory effect on cell proliferation was noted. In LPS-induced murine endotoxemia, STOMAPET prevents mortality, improves the decrease in body mass, and prevents the drop in temperature. Case reports of companion animals with oral diseases ameliorated after STOMAPET treatment are presented. Conclusions: Preclinical studies confirmed the safety of STOMAPET and its pharmacological potential. The results of the veterinary case reports are also encouraging. More studies are needed to find the precise mechanism of action in correlation to chemical composition.

Abstract
INTRODUCTION Pain is considered an unpleasant sensory and emotional experience, being considered as one of the most important causes of human suffering. Computational chemistry associated with bioinformatics has stood out in the process of developing new drugs, through natural products, to manage this condition. OBJECTIVE To analyze, through literature data, recent molecular coupling studies on the antinociceptive activity of essential oils and monoterpenes. DATA SOURCE Systematic search of the literature considering the years of publications between 2005 and December 2019, in the electronic databases PubMed and Science Direct. ELIGIBILITY CRITERIA Were considered as criteria of 1) Biological activity: non-clinical effects of an OE and/or monoterpenes on antinociceptive activity based on animal models and in silico analysis, 2) studies with plant material: chemically characterized essential oils and/or their constituents isolated, 3) clinical and non-clinical studies with in silico analysis to assess antinociceptive activity, 4) articles published in English. Exclusion criteria were literature review, report or case series, meta-analysis, theses, dissertations, and book chapter. RESULTS Of 16,006 articles, 16 articles fulfilled all the criteria. All selected studies were non-clinical. The most prominent plant families used were Asteraceae, Euphorbiaceae, Verbenaceae, Lamiaceae, and Lauraceae. Among the phytochemicals studied were α-Terpineol, 3-(5-substituted-1,3,4-oxadiazol-2-yl)-N'-[2-oxo-1,2-dihydro-3H-indol-3-ylidene] propane hydrazide, β-cyclodextrin complexed with citronellal, (-)-α-bisabolol, β-cyclodextrin complexed with farnesol, and p-Cymene. The softwares used for docking studies were Molegro Virtual Docker, Sybyl®X, Vlife MDS, AutoDock Vina, Hex Protein Docking, and AutoDock 4.2 in PyRx 0.9. The molecular targets/complexes used were Nitric Oxide Synthase, COX-2, GluR2-S1S2, TRPV1, β-CD complex, CaV1, CaV2.1, CaV2.2, and CaV2.3, 5-HT receptor, delta receptor, kappa receptor, and MU (μ) receptor, alpha adrenergic, opioid, and serotonergic receptors, muscarinic receptors and GABAA opioid and serotonin receptors, 5-HT3 and M2 receptors. Many of the covered studies used molecular coupling to investigate the mechanism of action of various compounds, as well as molecular dynamics to investigate the stability of protein-ligand complexes. CONCLUSIONS The studies revealed that through the advancement of more robust computational techniques that complement the experimental studies, they may allow some notes on the identification of a new candidate molecule for therapeutic use.

Abstract
E. adenophorum has reported to cause hepatotoxicity. But, the precise effects of E. adenophorum on hepatocytes is unclear. Saanen goats were fed on E. adenophorum to detect the cytotoxicity effects of E. adenophorum on hepatocytes. Our study has shown that the typical apoptotic features, the increasing apoptotic hepatocytes and activated caspase-9, −3 and the subsequent cleavage of PARP indicated the potent pro-apoptotic effects of E. adenophorum. Moreover, the translocation of Bax and Cyt c between mitochondria and cytosol triggering the forming of apoptosome proved that the mitochondria-mediated apoptosis was triggered by E. adenophorum. Furthermore, E. adenophorum increased the MDC-positive autophagic vacuoles and the subcellular localization of punctate LC3, the ratio of LC3-II/LC3-I and the protein levels of Beclin 1, but decreased that of P62, indicating the potent pro-autophagic effects of E. adenophorum. In addition, E. adenophorum significantly inhibited the protein leves of p-PI3K, p-Akt and p-mTORC1, but increased PTEN and p-AMPK. Also, the p-mTORC2 and p-Akt Ser473 were inhibited, indicating that the supression of mTORC2/Akt pathway could induce the autophagy of hepatocytes. The autophagy-realted results indicated that the inhibition of PI3K/Akt/mTORC1- and mTORC2/Akt-mediated pathways contributed to the pro-autophagic activity of E. adenophorum. These findings provide new insights to understand the mechanisms involved in E. adenophorum-caused hepatotoxicity of Saanen goat.

Abstract
The antifungal activity of oils extracted from Eupatorium adenophorum was tested against five phytopathogens in vitro. Oil extracts inhibited the mycelial growth of Phytophthora capsici which causes phytophthora blight in pepper. The minimum inhibitory concentration of oils against P. capsici was 500μg/ml after 7days incubation. At the ultrastructural level, oil extracts caused complete disorganization of intracellular organelles, cytoplasm depletion, disruption of cytoplasmic membranes and the cell wall. Membrane permeability increased with the increasing concentration of oil extracts. These results suggested that these oil extracts exhibited multiple modes of action including disruption of the cell membrane system. Furthermore, oil extracts combined with synthetic fungicides synergistically inhibited mycelial growth of P. capsici, which creates the possibility of reducing fungicide concentration needed to successfully control phytophthora blight in commercial pepper production. This study's use of multiple methods of analysis has increased our understanding of the mode of action of E. adenophorum oil extracts against P. capsici.

E. adenophorum induces Cell Cycle Arrest and Apoptosis of Splenocytes through the Mitochondrial Pathway and Caspase Activation in Saanen Goats. Sci Rep 2015; 5:15967.

Abstract
The precise cytotoxicity of E. Adenophorum in relation to the cell cycle and apoptosis of splenocytes in Saanen goats remains unclear. In the present study, 16 Saanen goats were randomly divided into four groups, which were fed on 0%, 40%, 60% and 80% E. adenophorum diets. The results of TUNEL, DAPI and AO/EB staining, flow cytometry analysis and DNA fragmentation assays showed that E. adenophorum induced typical apoptotic features in splenocytes, suppressed splenocyte viability, and caused cell cycle arrest in a dose-dependent manner. However, westernblot, ELISA, qRT-PCR and caspase activity analyses showed that E. adenophoruminhibited Bcl-2 expression, promoted Bax translocation to the mitochondria, triggered the release of Cytc from the mitochondria into the cytosol, and activated caspase-9 and -3 and the subsequent cleavage of PARP. Moreover, in E. adenophorum-induced apoptosis, the protein levels of Fas, Bid, FasL and caspase-8 showed no significant changes. E. adenophorum treatment induced the collapse of ΔΨm. Moreover, these data suggested that E. adenophorum induces splenocyte apoptosis via the activation of the mitochondrial apoptosis pathway in splenocytes. These findings provide new insights into the mechanisms underlying the effects of E. adenophorum cytotoxicity on splenocytes.

However, the protein levels of Fas/FasL, Bid and caspase-8 did not appear significant changes in the process of E. adenophorum-induced apoptosis. Moreover, E. adenophorum administration slightly decreased Bcl-2 expression, promoted Bax translocation to mitochondria, triggered the release of Cyt c from mitochondria into cytosol and activated caspase-9, -3, and cleaved PARP. The mitochondrial p53 translocation was significantly activated, accompanied by a significant increase in the loss of ΔΨm, Cyt c release and caspase-9 activation. Above all, these data suggest that E. adenophorum induces renal cells apoptosis via the activation of mitochondria-mediated apoptosis pathway in renal cells. These findings may provide new insights to understand the mechanisms involved in E. adenophorum-caused cytotoxicity of renal cells.

Abstract
9-Oxo-10, 11-dehydroageraphorone (euptox A), a cadenine sesquiterpene, is the main toxin from Eupatorium adenophorum. The aim of the present study was to examine the induction and mechanism of HeLa cell apoptosis by euptox A. The apoptosis‑inducing effect of the euptox A on HeLa cells was examined by MTT assay. The underlying mechanism was analyzed by flow cytometry and quantitative PCR. Flow cytometry results suggested that euptox A effectively inhibited the proliferation of HeLa cells, arrested the cell cycle transition from S to G2/M phase, did not continue to complete the cell cycle activity (mainly from 4 times and mitosis), and induced cell proliferation. The RT-qPCR detection results showed that euptox A induced apoptosis by improving the gene expression level of apoptotic proteases such as caspase-10 in HeLa cells. Its mechanism of action was associated with the upregulation of apoptotic gene expression and arresting of the cell cycle.

Abstract
BACKGROUND Animal acariasis is one of the important veterinary skin diseases. Chemical drugs have been widely used to treat and control this kind of disease. But many chemicals control could increase resistance in target species, toxicity and environmental hazards. We found that the 9-oxo-10, 11-dehydroageraphorone (euptox A) extracted from E. adenophorum has strong toxicity against P. cuniculi in vitro, but the in vivo acaricidal actions of euptox A have yet to be investigated. RESULTS A 14-day experiment was performed using rabbits that were naturally infested with P. cuniculi on a farm. Rabbits were randomly divided into five groups; animals in groups A, B and C were treated in each ear topically with 4.0 ml of 2.0 and 1.0 g/L (w/v) euptox A, respectively. Animals in groups D and E were treated with ivermectin (by injection; positive controls) and glycerol with water only (by embrocation; negative controls), respectively. Each rabbit was treated twice with separate treatments on days 0 and 7. Rabbits were observed daily and detailed examinations were performed on days 0, 7 and 14, to inspect the presence or absence of mites and scabs/crusts. Seven days after the initial treatment, the mean clinical scores (presence of scabs/crusts) decreased from 3.48, 3.37, 3.43 and 3.45 to 0.37, 0.42, 0.78 and 0.38 in the ears of animals in groups A, B , C and D, respectively, which were similar to the observations recorded in the positive control rabbits. However, the clinical score for negative control rabbits did not increase significantly (P > 0.05) during the experiment, and this changed from 3.32 to 3.37 in the ears, and there were no significant differences in clinical efficacy between left and right ears. After two treatments (0 and 7 d), the rabbits in groups A, B, C and D had recovered completely 14 days after the last treatment and no recurrences of infection were observed. CONCLUSIONS These results indicate that euptox A was potent compounds for the effective control of animal P. cuniculi in vivo.

Abstract
This study evaluated toxic efficacy of Eupatorium adenophorum extracts, against the Kunming mice. In acute study, we firstly tested median lethal dose (LD50) in mice of three cadinene sesquiterpenes 2-deoxo-2-(acetyloxy)-9-oxoageraphorone (DAOA), 9-oxo-agerophorone (OA) and 9-oxo-10,11-dehydro-agerophorone (ODA) from Eupatorium adenophorum (Ea). DAOA (215-4640 mg/kg BW, given orally) showed lowest LD50 at 926 mg/kg BW for male mice in contrast with OA (1470 mg/kg BW) and ODA (1470 mg/kg BW). In sub-acute study, repeated doses (75-300 mg/kg BW, for 7 days) of DAOA/OA increased blood parameters, liver and spleen index in dose dependent relationship, along with decrease in thymus index. The blood biochemical and histopathological examination showed that DAOA/OA dose 300 mg/kg BW significantly causes pathological changes of hepatic lobules and hepatocytes, which are consistent with cholestasis and hepatic injury. 75 mg/kg dose of DAOA/OA was found to be approximately/totally safe over the span of 7 days treatment showing no change in all above described parameters. Cadinene sesquiterpenes guarantee low risk to environment as a type of low toxic botanical components, which may find potential application in biopesticides development field.

Indian freshwater edible snail Bellamya bengalensis lipid extract prevents T cell mediated hypersensitivity and inhibits LPS induced macrophage activation. JOURNAL OF ETHNOPHARMACOLOGY 2014; 157:320-329. [PMID: 25291010 DOI: 10.1016/j.jep.2014.09.009] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/08/2014] [Revised: 08/04/2014] [Accepted: 09/05/2014] [Indexed: 06/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Soup prepared from the foot of fresh water edible snail, Bellamya bengalensis, is traditionally consumed by the tribes of Jharkhand against rheumatism like bone and joint inflammation. As rheumatism has underlying involvement of cell mediated hypersensitivity, in vivo delayed-type hypersensitivity (DTH) model and in vitro LPS-induced macrophage signaling were studied to delineate the mechanism by which Bellamya bengalensis exerts its ethnomedicinal function. Since the whole meat is consumed, the lipid of Bellamya bengalensis (BBL) was hypothesized to be the active part. METHODS AND MATERIALS BBL isolated from the foot part of this species, was characterized and given by gavage daily (10mg BBL/kg; 20mg BBL/kg) to mice for 3 weeks prior to initiating development of DTH. Effects of DTH induced changes in paw diameter, serum nitric oxide (NO), serum tumor necrosis factor (TNF)-α level, CINC1 level, splenic CD4(+)/CD8(+) cell ratios, and level of splenic Treg cells were then compared with values in untreated control mice. In vitro effect of BBL on LPS-stimulated macrophage, the immune cell that is active in DTH, was assessed by NF-kB p65 nuclear translocation, reactive oxygen species (ROS), TNFα, and NO production. RESULTS BBL was characterized, and its supplementation in situ led to significant decrease in paw edema, tissue myeloperoxidase activity, NO level, serum TNFα level and CINC 1 level as well as decrease in splenic CD4(+)/CD8(+) ratios and increase in level of Treg cells. BBL was shown to inhibit ROS, NO, and TNFα production along with NF-kB p65 nuclear translocation in LPS stimulated macrophage. CONCLUSION Bellamya bengalensis, traditionally used against diseases with underlying etiology of cell mediated immunity as in rheumatism, which acts through inhibition of overexpressed cell mediated immunity. The factor exerting this activity probably is the oleic acid and cyclopropane fatty acid rich lipid, isolated after the ethnomedicinal clue, from the foot of this species.

[PMID: 24631419 DOI: 10.1016/j.exppara.2014.02.009] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2013] [Revised: 08/24/2013] [Accepted: 02/19/2014] [Indexed: 01/10/2023]
Abstract
The acaricidal activity of the 9-oxo-10,11-dehydroageraphorone (euptox A), a cadenine sesquiterpene from Eupatorium adenophorum (E. adenophorum) against Sarcoptes scabiei and Psoroptes cuniculi was tested in vitro. A complementary log-log (CLL) model was used to analyze the data of the toxicity tests in vitro. The results showed euptox A had strong toxicity against mites, killing all S. scabiei at 3 and 4 mg/ml (m/v) concentration, while 4 mg/ml euptox A was also found to kill all P. cuniculi within a 4 h period. Similarly, 2, 3 and 4 mg/ml concentration of euptox A had strong toxicity against S. scabiei, with median lethal time (LT50) values at 0.687, 0.526, 0.326 h, respectively. 3 mg/ml and 4 mg/ml showed strong acaricidal action against P. cuniculi; the LT50 values were 0.693 and 0.493 h, respectively. The median lethal concentration (LC50) values were 1.068 mg/ml for Scabies mite and 0.902 mg/ml for P. cuniculi in 2 h. The results indicate that euptox A has strong acaricidal activity and may exploit as novel drugs for the effective control of animal acariasis.

Immunomodulatory Activity and Protective Effects of Polysaccharide from Eupatorium adenophorum Leaf Extract on Highly Pathogenic H5N1 Influenza Infection. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:194976. [PMID: 24159339 PMCID: PMC3789439 DOI: 10.1155/2013/194976] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/01/2013] [Revised: 08/12/2013] [Accepted: 08/20/2013] [Indexed: 12/22/2022]
Abstract
The development of novel broad-spectrum, antiviral agents against H5N1 infection is urgently needed. In this study, we evaluated the immunomodulatory activities and protective effect of Eupatorium adenophorum polysaccharide (EAP) against the highly pathogenic H5N1 subtype influenza virus. EAP treatment significantly increased the production of IL-6, TNF-α, and IFN-γ both in vivo and in vitro as measured by qPCR and ELISA. In a mouse infection model, intranasal administration of EAP at a dose of 25 mg/kg body weight prior to H5N1 viral challenge efficiently inhibited viral replication, decreased lung lesions, and increased survival rate. We further evaluated the innate immune recognition of EAP, as this process is regulated primarily Dectin-1 and mannose receptor (MR). These results indicate that EAP may have immunomodulatory properties and a potential prophylactic effect against H5N1 influenza infection. Our investigation suggests an alternative strategy for the development of novel antiinfluenza agents and benefits of E. adenophorum products.
