The aim of this study was to determine the anti-hepatitis B effect of isochlorogenic acid A isolated from Laggera alata (Asteraceae), a traditional Chinese herbal medicine.Materials and methods
The anti-hepatitis B activity of isochlorogenic acid A was evaluated by the d-galactosamine (D-GalN)-induced HL-7702 hepatocyte damage model and the HBV-transfected HepG2.2.15 cells.Results
Isochlorogenic acid A significantly improved HL-7702 hepatocyte viability and markedly inhibited the productions of HBsAg and HBeAg. The inhibitory rates of isochlorogenic acid A on the HBsAg and HBeAg expressions were 86.9% and 72.9%, respectively. In addition, isochlorogenic acid A declined markedly the content of hepatitis B virus covalently closed circular DNA (HBV cccDNA) and induced significantly the heme oxygenase-1 (HO-1) expression in HepG2.2.15 cells.Conclusions
Isochlorogenic acid A was verified to possess the potent anti-hepatitis B activity. The anti-HBV target of isochlorogenic acid A is probably associated with blocking the translation step of the HBV replication. Overexpression of HO-1 may contribute to the anti-HBV activity of isochlorogenic acid A by reducing the stability of the HBV core protein and thus blocking the refill of nuclear HBV cccDNA. Additionally, the hepatoprotective effect of isochlorogenic acid A could be achieved by its antioxidative property and induction of HO-1. 相似文献2.

Jasminum officinale L. var. grandiflorum (JOG) is a folk medicine used for the treatment of hepatitis in south of China. Phytochemical studies showed that secoiridoid glycosides are the typical constituents of this plant.Aim of the study
The present study was undertaken to evaluate the effect of oleuropein (Ole) derived from the flowers of JOG on hepatitis B virus (HBV) replication in HepG2 2.2.15 cell line in vitro and duck hepatitis B virus (DHBV) replication in ducklings in vivo.Material and methods
The extracellular hepatitis B e antigen (HBeAg) and hepatitis B surface antigen (HBsAg) concentrations in cell culture medium were determined by ELISA. DHBV in duck serum was analyzed by dot blot.Results
Ole blocks effectively HBsAg secretion in HepG2 2.2.15 cells in a dose-dependent manner (IC50 = 23.2 μg/ml). Ole (80 mg/kg, intraperitoneally, twice daily) also reduced viremia in DHBV-infected ducks.Conclusion
Ole therefore warrants further investigation as a potential therapeutic agent for HBV infection. 相似文献3.

Aim of the study
In the Comoros Islands, the aerial parts of Flacourtia indica are used in traditional medicine to treat malaria. Because of the important use of this plant, the phytochemistry of the aerial parts was investigated.Materials and methods
Three compounds were isolated from the decoction of this plant material, Pyrocatechol, Homaloside D and Poliothrysoside. The in vitro antiplasmodial activity on the chloroquine-resistant strain (W2) of Plasmodium falciparum and the cytotoxicity on two complementary human cell lines (THP1, HepG2), of AcOEt extract obtained after liquid/liquid extraction of the decoction and pure compounds, were evaluated.Results
The Poliothrysoside isolated from the AcOEt extract presented a strong antiplasmodial activity (IC50 = 7.4 μM) and a good selectivity index (>28) similar to chloroquine.Conclusion
This study reports for the first time antiplasmodial activity for Flacourtia indica, for its AcOEt extract and the three major constituents and confirms its traditional use. 相似文献8.

Glycyrrhiza uralensis has been used for the treatment of gastrointestinal disorders, such as diarrhea, in several ancient cultures. Glycyrrhizin is the principal component of liquorice and lots of pharmacological effects have been demonstrated.Aim of the study
Heat-labile enterotoxin (LT), the virulence factor of enterotoxigenic Escherichia coli, induces diarrhea by initially binding to the GM1 on the surfaces of intestinal epithelial cells and consequently leading to the massive loss of fluid and ions from cells. Therefore, we evaluated the inhibitory effects of traditional medicinal herbs (TMH) on the B subunit of LT (LTB) and GM1 interaction.Materials and methods
The inhibitory effects of TMH on LTB-GM1 interaction were evaluated by GM1-enzyme-linked immunosorbent assay (ELISA). The likely active phytochemicals of these TMH were then predicted by in silico model (docking) and analyzed by in vitro (GM1-ELISA) and in vivo (patent mouse gut assay) models.Results
We found that various TMH, which have been ethnomedically used for the treatment of diarrhea, inhibited the LTB-GM1 interaction. Docking data showed that triterpenoids were the most active phytochemicals and the oleanane-type triterpenoids presented better LTB-binding abilities than other types of triterpenoids. Moreover, by in vitro and in vivo models, we demonstrated that glycyrrhizin was the most effective oleanane-type triterpenoid that significantly suppressed both the LTB-binding ability (IC50 = 3.26 ± 0.17 mM) and the LT-induced fluid accumulation in mice.Conclusions
We found an LT inhibitor, glycyrrhizin, from TMH by in silico, in vitro, and in vivo analyses. 相似文献9.

Codiaeum variegatum, grown in many varieties, has been widely used as a houseplant based on its brightly decorative foliage. In addition, a variety of this plant has been used for a long time against bloody diarrhea by the local population in Cameroon.Aim of the study
In our previous study, the aqueous extract of this plant and an isolated sub-fraction exhibited significant anti-amoebic activity on axenic culture of Entamoeba histolytica. Due to the medicinal value of these extracts, we promptly initiated to investigate their genotoxic and mutagenic potential in order to assure their safe and rationale usage in traditional healthcare system.Material and methods
Both extracts were incubated with L5178Y mouse lymphoma cells, primary hepatic cells and HepG2 human hepatocellular carcinoma cells and their genotoxicity and mutagenicity were evaluated by quantifying DNA damage and chromosomal aberrations through comet assay, micronucleus assay and mouse lymphoma mutation assay.Results
The aqueous extract of Codiaeum variegatum is not cytotoxic up to 2000 µg/mL while the amoebicidal fraction is significantly cytotoxic (≤ 40–55%) on L5178Y mouse lymphoma and HepG2 cells at concentrations higher than 500 µg/mL. Besides, no significant DNA damage and induction of micronucleus formation were identified at concentrations up to 2000 µg/mL. Moreover, the mutagenic potential of these extracts after short (4 h) and long term (24 h) treatment, revealed no significant gene mutation induction.Conclusion
The aqueous extract of Codiaeum variegatum and the amoebicidal fraction SF9B are neither genotoxic on non-competent or metabolic competent cell lines, nor mutagenic in mouse lymphoma mutation assay and therefore they could be safely used at lower doses for medicinal purpose. 相似文献10.

Aim of the study
Caesalpinia bonduc (Lin.) Roxb. is a known drug in Ayurveda to treat various diseases specifically tumors, cysts and cystic fibrosis (CF). The aim of this study was to assess in vitro as well as in vivo antimicrobial activity of Caesalpinia bonduc seeds.Materials and methods
The in vitro antimicrobial activities of seed coat and seed kernel extracts were investigated by microbroth dilution assay. In vivo activities of hydro-alcoholic extracts were investigated in rat models of chronic Pseudomonas aeruginosa pneumonia mimicking that in patients with cystic fibrosis.Results
Various extracts of plant seeds exhibited in vitro antimicrobial activities in a range of 22–350 μg/ml. The extracts also showed activity against methicillin resistant (MR) Staphylococcus aureus and ampicillin resistant (AR) Pseudomonas aeruginosa as in the sensitive strains. In rat model of chronic Pseudomonas aeruginosa pneumonia, hydro-alcoholic extracts of Caesalpinia bonduc seed kernel (CBSK) and Caesalpinia bonduc seed coat (CBSC) were injected subcutaneously in the test groups of animals. The control groups were treated with cortisone and saline. Two weeks after challenge with Pseudomonas aeruginosa, the CBSK treated animals showed a significant bacterial clearance from the lungs (P < 0.04) and less severe incidence of lung abscess (P < 0.05).Conclusion
Results showed that Caesalpinia bonduc may have the potential to be promising natural medicine, with other forms of treatments, for CF patients with chronic Pseudomonas aeruginosa lung infections. 相似文献12.

Aim of the study
To determine the toxicity and anti-trypanosomal activity of the ethanolic extract of Azadirachta indica (Maliacea) stem bark, through in vivo and in vitro approach using Trypanosoma brucei brucei.Materials and methods
Graded concentrations (100, 200, 400, 800, 1600 and 3200 mg/kg) of the crude stem bark ethanolic extract of Azadirachta indica, Hochst ex. A. Dc. (Maliacea) was tested for acute toxicity in 35 out bred Swiss (Wister) adult albino rats of both sexes. Secondly, the in vitro activity in test tubes and in vivo activity of the extract in 30 out bred Swiss (Wister) adult albino rats against Trypanosoma brucei brucei strain NITR/14 (Federe) was evaluated in a graded dose manner.Results
The calculated intra-peritoneal LD50 of the extract was 870 mg/kg and produced toxicity at high doses (>800 mg/kg). Graded concentrations of the ethanolic extract produced remarkable in vitro activity against Trypanosoma brucei brucei within seconds of inoculation. It also suppressed the establishment of parasitaemia at 100 mg/kg when administered simultaneously with infection in vivo. Similarly, at 200 and 400 mg/kg, the extract administered at the onset of parasitaemia for 4 consecutive days reduced parasitaemia, modulated declined packed volume (PCV) changes by day 48 post-infection in vivo.Conclusion
The results confirm that the folkloric medicinal application of the extract of Azadirachta indica (Maliacea) has a pharmacological basis. Further investigation is however, needed to optimize the effectiveness of the extract. 相似文献13.

Zanthoxylum capense Thunb. (Rutaceae) is a medicinal plant traditionally used in Mozambique to treat tuberculosis.Aims of the study
The main aim of the study was to find antimycobacterial lead compounds from Zanthoxylum capense. Another goal was to provide scientific validation for the use of this plant in traditional medicine.Methods and materials
By bioassay-guided fractionation, 16 compounds were isolated and screened for their in vitro antimycobacterial activity against two different strains of Mycobacterium tuberculosis. Their in vitro cytotoxicity to human THP-1 macrophages was also assessed. The compounds with favourable selectivity index values (SI>10) were further investigated for their ability to inhibit the growth of Mycobacterium tuberculosis H37Rv in an intracellular macrophage model of infection.Results
The best results were obtained for a benzophenanthridine alkaloid, decarine (1), and an N-isobutylamide, N-isobutyl-(2E,4E)-2,4-tetradecadienamide (15), which showed high activity against Mycobacterium tuberculosis H37Rv (MIC of 1.6 μg/ml), and a low macrophage cytotoxicity (IC50>60 μg/ml), indicating considerable selective activity. The benzophenanthridine alkaloid 6-acetonyldihydronitidine (6) revealed cytotoxicity (IC50 1.7 μg/ml), despite the determined MIC of 6.2–12.5 μg/ml. In infected macrophages, decarine (1) was able to reduce bacterial survival by almost two log units at a concentration of 6.2 μg/ml 5 days post-drug exposure. Compound 15 exhibited an intermediate activity at drug concentrations ranging from 6.2 to 25 μg/ml.Conclusions
The high antimycobacterial activity of decarine found, both in vitro and ex vivo against mycobacteria, and the low cytotoxicity towards human macrophages indicate that it may be valuable as a lead scaffold for the development of anti-TB drugs. 相似文献14.

Aims of the study
Calophyllum brasiliense (Camb.) is a medicinal tree that grows particularly in the hilly and forested regions of Brazil. Preparations from its stem bark are popular remedies for the treatment of chronic ulcers. Since earlier investigations on bark extracts evidenced gastroprotective and gastric acid inhibitory properties, this study evaluated the effects of hydroethanolic extract (HEECb) and the dichloromethanic fraction (DCMF), from Calophyllum brasiliense stem bark, against Helicobacter pylori, in vitro and in vivo.Materials and methods
The in vitro assays were performed using the disk diffusion and broth microdilution methods to determine the minimum inhibitory concentration (MIC) values. The test substances were evaluated in vivo taking into account the delay in the gastric ulcer healing in Wistar rats, infected with Helicobacter pylori.Results
DCMF appeared the most active and potent in vitro against Helicobacter pylori growth with an MIC of 31 μg/mL. In the in vivo assays, rats ulcerated by acetic acid, and inoculated with Helicobacter pylori showed a marked delay in ulcer healing. Treatment with HEECb (50, 100 and 200 mg/kg) and DCMF (100 and 200 mg/kg) reduced the ulcerated area in a dose-dependent manner. While DCMF, at 200 mg/kg, increased the prostaglandin E2 (PGE2) level, both HEECb and DCMF decreased the number of urease-positive animals, as confirmed by the reduction of Helicobacter pylori presence in histopathological analysis.Conclusion
The results suggest that the antiulcer activity of Calophyllum brasiliense is due, in part, to its anti-Helicobacter pylori action, validating the popular use of this species. 相似文献15.

Ethnopharmacological relevance
Phyllanthus urinaria is widely used as anti-inflammatory, anti-diarrheal and hepatoprotective medicines in Asian countries such as India, China and Thailand. In Thailand, Phyllanthus urinaria is traditionally used as an adjuvant or alternative medicine for cancer patients, including liver cancer. However, there is limited scientific evidence supporting its use in cancer particularly hepatocellular carcinoma.Aim of the study
To investigate the cytotoxic effect of Phyllanthus urinaria extract on human hepatocellular carcinoma HepG2 cells and the effect on oxidative phosphorylation by isolated rat liver mitochondria.Materials and methods
HepG2 cells and isolated rat liver mitochondria were treated with the 50% methanolic extract of Phyllanthus urinaria. Cytotoxicity of the extract was assessed by trypan blue exclusion and MTT assay. Rates of oxygen consumption of isolated mitochondria were determined with a Clark oxygen electrode.Results
It was found that the hydromethanolic extract induced cell death of HepG2 cells in a dose-dependent fashion. The IC50 of Phyllanthus urinaria extract measured by trypan blue exclusion and MTT assay were 431 ± 65 μg/ml and 445 ± 62 μg/ml, respectively. Morphological changes of the cells were also observed. With isolated rat liver mitochondria, the extract slightly stimulated mitochondrial state 4 respiration but profoundly depressed state 3 respiration and respiratory control ratio.Conclusions
The extract impairs energy metabolism by acting as inhibitor of oxidative phosphorylation and weak mitochondrial uncoupler. These mitochondrial effects may play a role in the cytotoxic action of Phyllanthus urinaria extract on HepG2 cells. These results provide preliminary experimental evidence supporting the use of Phyllanthus urinaria against hepatocellular carcinoma and open the possibility of considering this plant an adjunctive medicine for the treatment of this deadly disease. 相似文献17.

Ethnopharmacological relevance
The volatile essential oil derived from the plant Melaleuca alternifolia, also called tea tree oil (TTO), is largely employed for its antimicrobial properties against several human pathogens. It is used in many topical formulations to treat cutaneous infections.Aim of the study
Since very few studies have been done on the safety and toxicity of the crude Melaleuca alternifolia essential oil, current investigation evaluates the possible genotoxic effects of TTO in human lymphocyte cultures.Material and methods
The composition of current TTO sample was determined by GC/MS and NMR. The level of cytotoxicity in TTO treated cultures was determined by decrease of mitotic index when compared to that in negative control. The genotoxic potential of TTO was assessed by the in vitro mammalian cell micronucleus and the chromosome aberrations (CA) tests.Results
Twenty-seven compounds were identified, accounting for 98.9% of the constituents. Terpinen-4-ol (42.8%), γ-terpinene (20.4%), p-cymene (9.6%), α-terpinene (7.9%), 1,8-cineole (3%), α-terpineol (2.8%) and α-pinene (2.4%) were the major compounds of the oil sample. None of the tested TTO concentrations (95 μg/ml, 182 μg/ml and 365 μg/ml) caused a significant increase in the observed frequencies of micronuclei when compared to those in the untreated cultures (negative control). Additionally, no significant differences regarding the frequencies of CA were observed among the tested TTO concentrations and the negative control.Conclusions
Results demonstrate that TTO, in the tested concentrations, is not genotoxic in in vitro mammalian cells. 相似文献18.
Ethnopharmacological relevance
Pyrrolizidine alkaloids (PAs) are a group of heterocyclic phytotoxins present in a wide range of plants. The consumption of PA-containing medicinal herbs or PA-contaminated foodstuffs has long been reported to cause human hepatotoxicity. However, the degrees of hepatotoxicity of different PAs are unknown, which makes it difficult to determine a universal threshold of toxic dose of individual PAs for safe regulation of PA-containing natural products. The aim of the present study is to develop a simple and convenient in vitro model to assess the hepatotoxicity of different PAs.Material and methods
Six common cytotoxicity assays were used to evaluate the hepatotoxicity of different PAs in human hepatocellular carcinoma HepG2 cells.Results
The combination of MTT and bromodeoxyuridine incorporation (BrdU) assays demonstrated to be a suitable method to evaluate the toxic potencies of various PAs in HepG2 cells, and the results indicated that otonecine-type PA (clivorine: IC20=0.013±0.004 mM (MTT), 0.066±0.031 mM (BrdU)) exhibited significantly higher cytotoxic and anti-proliferative effects than retronecine-type PA (retrorsine: IC20=0.27±0.07 mM (MTT), 0.19±0.03 mM (BrdU)). While as expected, the known less toxic platyphylline-type PA (platyphylline: IC20=0.85±0.11 mM (MTT), 1.01±0.40 mM (BrdU)) exhibited significantly less toxicity. The different cytotoxic and anti-proliferative potencies of various PAs in the same retronecine-type could also be discriminated by using the combined MTT and BrdU assays. In addition, the developed assays were further utilized to test alkaloid extract of Gynura segetum, a senecionine and seneciphylline-containing herb, the overall cytotoxicity of two PAs in the extract was comparable to that of these two PAs tested individually.Conclusion
Using the developed in vitro model, the cytotoxicity of different PAs and the extract of a PA-containing herb were investigated in parallel in one system, and their different hepatotoxic potencies were determined and directly compared for the first time. The results suggested that the developed model has a great potential to be applied for the quick screening of the toxicity of PAs and PA-containing natural products. 相似文献19.

Aim of the study
The in vitro antiplasmodial activity and cytotoxicity of methanolic and dichloromethane extracts from five Congolese plants were evaluated. The plants were selected following an ethnobotanical survey conducted in D.R. Congo and focusing on plants used traditionally to treat malaria. The in vivo antimalarial activity of aqueous and methanolic extracts active in vitro was also determined in mice infected by Plasmodium berghei berghei.Materials and methods
The growth inhibition of Plasmodium falciparum strains was evaluated using the measurement of lactate dehydrogenase activity. The extracts (aqueous, CH3OH, EtOH and CH2Cl2) were prepared by maceration and tested in vitro against the 3D7 (chloroquine sensitive) and W2 (chloroquine resistant) strains of Plasmodium falciparum and against the human normal fetal lung fibroblasts WI-38 to determine the selectivity index. Some extracts were also used at the dose of 300 mg/kg to evaluate their activity in mice infected since 4 days by Plasmodium berghei.Results
Two plants presented a very high activity (IC50 < 3 μg/ml). These plants were Strychnos icaja roots bark (MeOH and CH2Cl2) and Physalis angulata leaves (MeOH and CH2Cl2). One plant (Anisopappus chinensis whole plant, MeOH and CH2Cl2) presented a high activity (IC50 < 15 μg/ml). The extracts of Anisopappus chinensis and Physalis angulata showed also a good inhibition of parasitemia in vivo. Flavonoids, phenolic acids and terpenes were identified in these plants by a general phytochemical screening method.Conclusion
Three plants showed a very interesting antiplasmodial activity (Anisopappus chinensis, Physalis angulata and Strychnos icaja) and one of them showed a good selectivity index (>10, Anisopappus chinensis). Anisopappus chinensis and Physalis angulata were also active in vivo. 相似文献20.
