Islam Shawon S, Nargis Reyda R, Qais N. Medicinal herbs and their metabolites with biological potential to protect and combat liver toxicity and its disorders: A review. Heliyon 2024; 10:e25340. [PMID: 38356556 PMCID: PMC10864916 DOI: 10.1016/j.heliyon.2024.e25340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 01/22/2024] [Accepted: 01/24/2024] [Indexed: 02/16/2024] Open
Abstract
The liver is an essential organ that helps the body with immunity, metabolism, and detoxification, among other functions. Worldwide, liver illnesses are a leading cause of mortality and disability. There are few effective treatment choices, but they frequently have unfavorable side effects. Investigating the potential of medicinal plants and their bioactive phytoconstituents in the prevention and treatment of liver disorders has gained more attention in recent years. An assessment of the hepatoprotective potential of medicinal plants and their bioactive secondary metabolites is the goal of this thorough review paper. To determine their hepatoprotective activity, these plants were tested against liver toxicity artificially induced in rats, mice and rabbits by chemical agents such as carbon tetrachloride (CCl4), paracetamol (PCM), thioacetamide (TAA), N-nitrosodiethylamine, d-galactosamine/lipopolysaccharide, antitubercular medicines (rifampin, isoniazid) and alcohol. To find pertinent research publications published between 1989 and 2022, a comprehensive search of electronic bibliographic databases (including Web of Science, SpringerLink, ScienceDirect, Google Scholar, PubMed, Scopus, and others) was carried out. The investigation comprised 203 plant species from 81 families in total. A thorough discussion was mentioned regarding the hepatoprotective qualities of plants belonging to several families, such as Fabaceae, Asteraceae, Lamiaceae, and Euphorbiaceae. The plant groups Asteraceae and Fabaceae were the most frequently shown to have hepatoprotective properties. The phytochemical constituents namely flavonoids, phenolic compounds, and alkaloids exhibited the highest frequency of hepatoprotective action. Also, some possible mechanism of action of some active constituents from medicinal plants was discussed in brief which were found in some studies. In summary, the information on medicinal plants and their potentially hepatoprotective bioactive phytoconstituents has been consolidated in this review which emphasizes the importance of further research to explore the efficacy and safety of these natural remedies for various liver ailments.

PHYTOCHEMISTRY 2022; 202:113308. [PMID: 35817204 DOI: 10.1016/j.phytochem.2022.113308] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Revised: 06/29/2022] [Accepted: 06/30/2022] [Indexed: 06/15/2023]
Abstract
Four undescribed trimethylated acylphloroglucinol meroterpenoids, hyjapones A-D, along with seven known analogues, were isolated from Hypericum japonicum Thunb. Hyjapone A represents the first example of a double norflavesones-caryophyllene hybrid featuring a rare 6/6/9/4/6/6 hexacyclic frame. Hyjapone D was isolated as a natural product for the first time. Their structures and absolute configurations were established by comprehensive spectroscopic data analyses and electronic circular dichroism (ECD) calculations. The anti-inflammatory activities of all compounds were evaluated using lipopolysaccharide-induced RAW264.7 cells. Hyperjapone A showed more pronounced anti-inflammatory effect through reducing the production of nitric oxide (IC50 value of 11.32 ± 2.10 μM) and proinflammatory cytokines. In addition, the mechanistic studies revealed hyperjapone A inhibited LPS-induced activation of nuclear factor-κB.

Abstract
Liver diseases are quite prevalant in many densely populated countries, including Bangladesh. The liver and its hepatocytes are targeted by virus and microbes, as well as by chemical environmental toxicants, causing wide-spread disruption of metabolic fuctions of the human body, leading to death from end-stage liver diseases. The aim of this review is to systematically explore and record the potential of Bangladeshi ethnopharmacological plants to treat liver diseases with focus on their sources, constituents, and therapeutic uses, including mechanisms of actions (MoA). A literature survey was carried out using Pubmed, Google Scholar, ScienceDirect, and Scopus databases with articles reported until July, 2020. A total of 88 Bangladeshi hepatoprotective plants (BHPs) belonging to 47 families were listed in this review, including Euphorbiaceae, Cucurbitaceae, and Compositae families contained 20% of plants, while herbs were the most cited (51%) and leaves were the most consumed parts (23%) as surveyed. The effect of BHPs against different hepatotoxins was observed via upregulation of antioxidant systems and inhibition of lipid peroxidation which subsequently reduced the elevated liver biomarkers. Different active constituents, including phenolics, curcuminoids, cucurbitanes, terpenoids, fatty acids, carotenoids, and polysaccharides, have been reported from these plants. The hepatoameliorative effect of these constituents was mainly involved in the reduction of hepatic oxidative stress and inflammation through activation of Nrf2/HO-1 and inhibition of NF-κB signaling pathways. In summary, BHPs represent a valuable resource for hepatoprotective lead therapeutics which may offer new alternatives to treat liver diseases.

[PMID: 33726778 PMCID: PMC7962269 DOI: 10.1186/s13020-021-00434-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Accepted: 02/18/2021] [Indexed: 12/13/2022] Open
Abstract
Background Non-alcoholic steatohepatitis (NASH) is an advanced form of non-alcoholic fatty liver disease (NAFLD) for which there is yet any standard pharmacotherapy. Traditional Chinese medicine formula such as Qushihuayu (QSHY) composing of multiple bioactive compounds has been used to treat NAFLD and NASH and shows beneficial effects over single compound treatment. This study aimed to investigate the mechanism of hepatoprotective effect of QSHY formula using a rat model. Methods Six-weeks old male Wistar rats were given methionine/choline supplemented (MCS) diet for 8 weeks and used as the blank control. Another 7 rats, which received methionine/choline deficient (MCD) diet in the first 6 weeks and a MCS&MCD (1:1) mixture diet in the last 2 weeks, were used as the model group. The groups of QSHY pre-treatment, low dosage, medium dosage and high dosage were given the same diet as the model group. Except for pre-treatment group (1 week in advanced of other groups), all QSHY treatment groups received QSHY formula by gavage every day since the MCD diet started. Results In the MCD diet group, the QSHY formula decreased the serum ALT and AST levels, lipid droplets, inflammation foci, FAS and α-SMA protein expression than MCD diet group. MAPK pathways phospharylation were markedly depressed by the QSHY formula. Moreover, QSHY formula enhanced PPAR-γ and p-p65 translocating into nucleus. The administration of QSHY increased hepatic mRNA levels of Transcription Factor 1 alpha (HNF1A), Hepatocyte Nuclear Factor 4 alpha (HNF4A) and Forkhead box protein A3 (FOXA3) which play a pivotal role in Hepatic stellate cell (HSCs) reprogramming. Conclusion These findings suggest that QSHY formula exerts a hepatoprotective effect against steatosis and fibrosis presumably via depressed MAPK pathways phosphorylation, reinforcement of PPAR-γ and p-p65 translocating into nucleus and enhanced HSCs reprogramming.

Abstract
Background This network pharmacology study aimed to identify the active compounds and molecular mechanisms involved in the effects of Hypericum japonicum on cholestatic hepatitis. We validated the findings in an alpha-naphthylisothiocyanate (ANIT) rat model of hepatotoxicity. Material/Methods The chemical constituents and targets of H. japonicum and target genes previously associated with cholestatic hepatitis were retrieved from public databases. A network was constructed using Cytoscape 3.7.2 software and the STRING database and potential protein functions were analyzed based on the public platform of bioinformatics. ANIT was used to induce cholestatic hepatitis in a rat model using 36 Sprague-Dawley rats, and this model was used to investigate intervention with 3 doses of quercetin (low-dose, 50 mg/kg; medium-dose, 100 mg/kg; and high-dose, 200 mg/kg), the main active component of H. japonicum. Levels of serum biochemical indexes were measured by commercial kits, and the messenger RNA (mRNA) levels of markers of liver and mitochondrial function and oxidative stress were detected by real-time reverse transcription-polymerase chain reaction (RT-PCR). Results The main active ingredients of H. japonicum were quercetin, kaempferol, and tetramethoxyluteolin, and their key targets included prostaglandin G/H synthase 2 (PTGS2), B-cell lymphoma-2 (BCL2), cholesterol 7-alpha hydroxylase (CYP7A1), and farnesoid X receptor (FXR). Quercetin intervention promoted recovery from cholestatic hepatitis. Conclusions The findings from this research provide support for future research on the roles of quercetin, kaempferol, and tetramethoxyluteolin in human liver disease and the roles of the PTGS2, BCL2, CYP7A1, and FXR genes in cholestatic hepatitis.

[PMID: 33061223 PMCID: PMC7522944 DOI: 10.14202/vetworld.2020.1528-1535] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Accepted: 07/07/2020] [Indexed: 12/22/2022] Open
Abstract
Background and Aim: Momordica charantia is a highly valued plant, widely distributed in the tropical and subtropical regions. The plant is reported to have a wide range of medicinal uses. This study was designed to explore the ameliorative potential of M. charantia methanol leaf extract in alloxan-induced diabetic animal model with a particular focus on the liver. Materials and Methods: Hepatoprotective effect of methanol leaf extract of M. charantia was assessed in alloxan-induced toxicity in 50 rats divided into five groups (A-E) (n=10). Group A normal control, Group B was toxicant group, and Group C animals received glibenclamide treatment while Groups D and E received extracts at 200 and 400 mg/kg doses, respectively. The experiment lasted for 28 days. Histopathological changes, blood glucose level, and serum enzymes such as aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase, oxidative status and caspase-9, and interleukin-1β (IL-1β) were evaluated. Results: Extract-treatment caused a decreased blood glucose level, markers of oxidative stress such as malondialdehyde and hydrogen peroxide (H2O2). Treatment of rats with leaf extract of M. charantia resulted in increased levels and activities of protein thiols, non-protein thiols, glutathione (GSH), glutathione peroxidase, glutathione S-transferase, and superoxide dismutase indicating its antioxidant potential. The liver section revealed mild distortion of the hepatic architecture compared to the toxicant group, while decreased expressions of caspase-9 and IL-1β in extract-treated groups was observed. Conclusion: The plant extract exhibited antioxidant, anti-apoptotic, and anti-inflammatory effects, thus showing its hepatoprotective property.

Abstract
Context Contamination of feedstuff with mixed mycotoxins is one of the frequent problems found in broiler chicken production, especially in tropical countries with a hot and humid climate, such as Thailand. Aims An in vivo study was conducted to examine the effects of Thunbergia laurifolia Linn. (TL) leaves on the growth performance, nutrient digestibility and antioxidant enzyme activity of broiler chicks fed naturally mycotoxin-contaminated feed. Methods In total, 375 1-day-old male Arbor Acre broilers were allotted into five experimental groups, with five replicates each (15 chicks per replicate). The experimental groups were mycotoxin-free basal corn–soybean diet (T1, control), diet with mixed mycotoxins (aflatoxin, fumonisins, tricothecene and ochratoxin, T2), T2 diet but supplemented with 1% (w/w) yeast glucomannan (GM, T3), T2 diet but supplemented with 2% (w/w) TL (T4) and T2 diet but supplemented with both 2% (w/w) TL and 1% (w/w) GM (T5). Feed intake, bodyweight gain, feed conversion ratio, mortality rate, nutrient digestibility and the activity of antioxidant enzymes were measured at Days 21 and 42. Key results Broilers in T4 and T5 groups had a significantly (P < 0.05) higher nutrient digestibility than those in the other groups at Day 42, while broilers in the T3, T4 and T5 groups had a significantly (P < 0.05) higher glutathione peroxidase activity than those in the other groups. There was no difference in the growth performance among the groups, except chicks that received the mixed mycotoxin-contaminated feed had a higher feed conversion ratio and ate more feed than did those in the control group. Conclusion It is concluded that 2% TL and 1% GM helped ameliorate the adverse effect of mycotoxin, improving nutrient digestibility and increased the glutathione peroxidase activity, but without a significant change in growth rate. Implications Herbal plant TL can be used as an alternative mycotoxin adsorbent in broiler production.

Abstract
Hypericum genus is traditionally known for its medicinal use and its therapeutic and antioxidant effects. However, the toxic effect of this plant has not been much explored. Our study aimed at investigating the effect of Hypericum humifusum (Hh) leaf extracts on oxidative stress parameters in male rats. For it, we first focused on the phytochemical analysis of the aqueous and methanolic extracts of Hh leaves. Hence, Wistar rats were treated per gavage for 30 days and divided into Control (1 mL/rat, distilled water), A200 group (200 mg/kg body weight (bw) aqueous extract), A400 group (400 mg/kg bw aqueous extract), M10 group (10 mg/kg bw methanolic extract), M20 group (20 mg/kg bw methanolic extract). The phytochemical analysis revealed the presence of tannins, flavonoids, steroids, carbohydrates, and phenolic compounds. Biochemical and histological investigations were performed in plasma and liver tissue. Liver tissue homogenates were used for the measurement of malondialdehyde (MDA), catalase (CAT) and superoxide dismutase (SOD) levels. At the same time, alanine transaminase (ALT), aspartate transaminase (AST) and lactate dehydrogenase (LDH) were assayed in plasma samples. Histological study was also conducted in liver. We showed that Hh extracts reduced relative liver weight and increased ALT, AST, LDH activities in treated groups compared to control group. These results were associated with an increase of MDA levels and a decrease of antioxidant enzyme activities (CAT and SOD) in liver tissues of treated rats. Histology of liver demonstrated several alterations showing necrosis, altered hepatocytes and lymphocyte migration mainly in A200 group and dilated sinusoids, foamy appearance of hepatocytes and lymphocyte accumulation in the other treated groups. This original work indicated that chronic consumption of Hh leaf extracts has no antioxidant effect but instead it induces oxidative stress and enhances markers of cell damage which was confirmed by histological study of liver rats.

[PMID: 29772655 PMCID: PMC6100316 DOI: 10.3390/molecules23051188] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2018] [Revised: 05/13/2018] [Accepted: 05/14/2018] [Indexed: 12/28/2022] Open
Abstract
Hypericum japonicum is traditionally used as a folk medicine to treat cholestasis and hepatitis. Quercetin 7-rhamnoside (Q7R) is one of the main flavonoid components of Hypericum japonicum and has been rarely studied. The aim of the present study was to evaluate the antioxidant activity and hepatoprotective potential of Q7R. In the in vitro experiments, DPPH, ABTS and ferric reducing antioxidant power (FRAP) assays were first performed to assess the antioxidant properties of Q7R, and then a H₂O₂-induced oxidative damage cellular model was used to determine the cytoprotective and antioxidant properties of Q7R in human liver L-02 cells. In the in vivo experiment, the hepatoprotective activity of Q7R was evaluated by carbon tetrachloride (CCl₄)-induced liver damage model in mice. The results of the three in vitro assays (DPPH, ABTS and FRAP) demonstrated that Q7R significantly exhibited antioxidant activity. The cell experiment results showed that Q7R possessed cytoprotective and antioxidant effects on H₂O₂-treated L-02 cells. In the in vivo experiments, Q7R suppressed the up-regulation of serum activities of ALT, AST, LDH and triglyceride (TG) levels with dose-dependency. Q7R down-regulated the production of MDA and increased the hepatic GSH content and antioxidant enzymes CAT activities. Hepatic morphological analysis was also performed to confirm the biochemical changes. In summary, these results suggested that Q7R could be considered as a potential source of natural antioxidants, and may become a promising candidate for the treatment of liver injury in the future.

ETHNOPHARMACOLOGICAL RELEVANCE The ripe seeds of Herpetospermum caudigerum have been used in Tibetan folk medicine for treatment of bile or liver diseases including jaundice, hepatitis, intumescences or inflammation. Previously reports suggested that the seed oil and some lignans from H. caudigerum exhibited protective effects against carbon tetrachloride (CCl4)-induced hepatic damage in rats, which may be related to their free radical scavenging effect. However, the protective effect of H. caudigerum against cholestasis is still not revealed. The aim of the present study was to investigate the pharmacological effect and the chemical constituents of the petroleum ether extract (PEE) derived from H. caudigerum against α-naphthylisothiocyanate (ANIT)-induced acute cholestasis in rats. MATERIALS AND METHODS Male cholestatic Sprague-Dawley (SD) rats induced by ANIT (60mg/kg) were orally administered with PEE (350, 700 and 1400mg/kg). Levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-Glutamyl transpeptidase (γ-GTP), total bilirubin (TBIL), direct bilirubin (DBIL) and total bile acid (TBA), as well as bile flow, and histopathological assay were evaluated. Hepatic malondialdehyde (MDA), myeloperoxidase (MPO), superoxide dismutase (SOD), glutathione S-transferase (GST), and nitric monoxide (NO) in liver were measured to explore the possible protective mechanisms. Phytochemical analysis of PEE was performed by gas chromatography-mass spectrometer (GC-MS). RESULTS PEE have exhibited significant and dose-dependent protective effect on ANIT-induced liver injury by reduce the increases in serum levels of ALT, AST, ALP, γ-GTP, TBIL, DBIL and TBA, restore the bile flow in cholestatic rats, and reduce the severity of the pathological tissue damage induced by ANIT. Hepatic MDA, MPO and NO contents in liver tissue were reduced, while SOD and GST activities were elevated in liver tissue. 49 compounds were detected and 39 of them were identified by GC-MS analysis, in which long-chain fatty acids were the main constituents. CONCLUSIONS PEE exhibited a dose-dependently protective effect on ANIT-induced liver injury in cholestatic rats with the potential mechanism of attenuated oxidative stress in the liver tissue, and the possible active compounds were long-chain fatty acids.

Abstract
Lead is a toxic metal that induces a wide range of behavioral, biochemical and physiological effects in humans. Oxidative damage has been proposed as a possible mechanism involved in lead toxicity. The current study was carried out to evaluate the antioxidant activities of Spirulina supplement against lead acetate -induced hepatic injury in rats. Five groups of rats were used in this study, Control, Lead acetate (100 mg/kg), Lead acetate (100 mg/kg) + 0.5 g/kg Spirulina, Lead acetate (100 mg/kg) + 1 g/kg Spirulina and Lead acetate + 25 mg/100 g Vitamin C (reference drug). All experimental groups received the oral treatment by stomach tube once daily for 4 weeks. Lead intoxication resulted in a significant increase in serum alanine transaminae (ALT), aspartate transaminae (AST) activities, liver homogenate tumor necrosis factor-α (TNF-α), caspase-3, malondialdehyde (MDA), nitric oxide (NO) levels and a significant decline of total serum protein, liver homogenate reduced glutathione (GSH) level and superoxide dismutase (SOD) activity. Both doses of Spirulina supplement as well as Vitamin C succeeded to improve the biochemical parameters of serum and liver and prevented the lead acetate-induced significant changes on plasma and antioxidant status of the liver. Both doses of Spirulina supplement had the same anti-apoptotic activity and high dose exhibited more antioxidant activity than that of low dose. In conclusion, the results of the present work revealed that Spirulina supplement had protective, antioxidant and anti-apoptotic effects on lead acetate-induced hepatic damage.

Assessment of a Flavone-Polysaccharide Based Prescription for Treating Duck Virus Hepatitis. PLoS One 2016; 11:e0146046.

Abstract
Because polysaccharide and flavone ingredients display good antiviral activity, we developed a flavone/polysaccharide-containing prescription that would be effective against duck viral hepatitis (DVH) and investigated its hepatoprotective effects. Flavones were derived from Hypericum japonicum (HJF) (entire herb of Hypericum japonicum Thunb) and Salvia plebeia (SPF) (entire herb of Salvia plebeia R. Br.), and polysaccharides were derived from Radix Rehmanniae Recens (RRRP) (dried root of Rehmannia glutinosa Libosch). This prescription combination was based on the theory of syndrome differentiation and treatment in traditional Chinese veterinary medicine. In vitro and in vivo experiments were conducted using the three single ingredients compared to the combined HRS prescription to determine their anti-duck hepatitis A viral (anti-DHAV) activity. The results showed that all experimental conditions displayed anti-DHAV activity, but the HRS prescription presented the best effect. To further investigate the hepatoprotective effect of the HRS prescription on DHAV-induced hepatic injury, we tested the mortality rate, the hepatic pathological severity score, plasma biochemical indexes of hepatic function, blood DHAV gene expression levels and peroxidation damage evaluation indexes and then analyzed correlations among these indexes. The results demonstrated that the HRS prescription significantly decreased the mortality rate, reduced the severity of hepatic injury, decreased the hepatic pathological severity score, depressed blood DHAV gene expression levels, and returned the indexes of hepatic function and peroxidation almost to a normal level. These results indicate that the HRS prescription confers an outstanding hepatoprotective effect, and we expect that it will be developed into a new candidate anti-DHAV drug.

Abstract
A rapid and sensitive assay based on ultra high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) was established and validated for the simultaneous determination of gallic acid, protocatechuic acid, vanillic acid, caffeic acid, epicatechin, isoquercitrin, vincetoxicoside B and quercetin in rat plasma using catechin and daidzein as the internal standards (IS). Plasma samples added internal standards were acidified with formic acid then pretreated by direct protein precipitation with acetonitrile. The separation of eight constituents was achieved on a C18 column with gradient elution using methanol and 0.2% acetic acid aqueous solution as the mobile phase and detected by multiple reaction monitoring using electrospray ionization source in the positive-negative ionization mode. The method was validated for sufficient specificity, precision, accuracy, and sensitivity over the concentration range of 10-6000 ng mL(-1) for gallic acid, 1.5-3000 ng mL(-1) for protocatechuic acid, 10-15000 ng mL(-1) for vanillic acid, 2-3600 ng mL(-1) for caffeic acid, 1.5-3600 ng mL(-1) for epicatechin, 4-6000 ng mL(-1) for isoquercitrin, 2-9000 ng mL(-1) for vincetoxicoside B, and 20-18000 ng mL(-1) for quercetin. The overall intra‑run precision and the inter‑run precision were showed in the range of 1.0-14.2% and 2.8-12.9%, respectively, and the accuracy was no more than 12.8%. This analytical method was successfully applied to investigate the pharmacokinetics of eight ingredients in rats after oral administration of Hypericum japonicum Thunb extract.

Abstract
The widely-used Chinese medicinal herb Hypericum japonicum, also known as Hypericum japonicum Thunb or Tianjihuang, displays potent anti-carcinogenic effects against liver cancer. However, the molecular mechanism underlying the therapeutic effects of Hypericum japonicum remains to be elucidated. The present study investigated the in vivo efficacy of ethyl acetate extract of Hypericum japonicum (EAEHJ) against tumor growth in an H22 cell-bearing liver cancer mouse model. Treatment with EAEHJ significantly reduced tumor weight, but had no effect on murine body weight. The results of the present study also showed that EAEHJ induced H22 cell apoptosis in vivo. In addition, the anti-carcinogenic effects of EAEHJ were investigated in vitro. The results of the present study demonstrate that both phospholipid asymmetry in the plasma membrane and mitochondrial membrane potential were deregulated in HepG2 human hepatoma cells, following treatment with EAEHJ. Treatment with EAEHJ also increased the ratio of pro-apoptotic B-cell lymphoma 2 (Bcl-2)-associated X protein (Bax) to anti-apoptotic Bcl-2, and activated the caspase-9 signaling pathway. These results suggest that EAEHJ is able to trigger the apoptosis of liver cancer cells via the mitochondria-dependent pathway.

Abstract
Background Hypericum japonicum Thunb. ex Murray is widely used as an herbal medicine for the treatment of hepatitis and tumours in China. However, the molecular mechanisms of its effects are unclear. Our previous research showed that extracts of H. japonicum can induce apoptosis in leukaemia cells. We also previously systematically analysed and isolated the chemical composition of H. japonicum. Methods The fluorescence polarisation experiment was used to screen for inhibitors of Bcl-2 proteins which are proved as key proteins in apoptosis. The binding mode was modelled by molecular docking. We investigated the proliferation attenuating and apoptosis inducing effects of active compound on cancer cells by MTT assay and flow cytometry analysis. Activation of caspases were tested by Western blot. A broad-spectrum caspase inhibitor Z-VAD-FMK was used to investigate the caspases-dependence. In addition, co-immunoprecipitation was performed to analyse the inhibition of heterodimerization between anti-apoptotic Bcl-2 proteins with pro-apoptotic proteins. Moreover, in vivo activity was tested in a mouse xenograph tumour model. Result Jacarelhyperol A (Jac-A), a characteristic constituent of H. japonicum, was identified as a potential Bcl-2 inhibitor. Jac-A showed binding affinities to Bcl-xL, Bcl-2, and Mcl-1 with Ki values of 0.46 μM, 0.43 μM, and 1.69 μM, respectively. This is consistent with computational modelling results, which show that Jac-A presents a favorable binding mode with Bcl-xL in the BH3-binding pocket. In addition, Jac-A showed potential growth inhibitory activity in leukaemia cells with IC50 values from 1.52 to 6.92 μM and significantly induced apoptosis of K562 cells by promoting release of cytochrome c and activating the caspases. Jac-A also been proved that its effect is partly caspases-dependent and can disrupt the heterodimerization between anti-apoptotic Bcl-2 proteins with pro-apoptotic proteins. Moreover, Jac-A dose-dependently inhibited human K562 cell growth in a mouse xenograph tumour model with low toxicity. Conclusion In this study, a characteristic constituent of H. japonicum, Jac-A, was shown to induce apoptosis in leukaemia cells by mediating the Bcl-2 proteins. Therefore, we propose a new lead compound for cancer therapy with a low toxicity, and have provided evidence for using H. japonicum as an anti-cancer herb.

Abstract
Hypericum japonicum Thunb. ex Murray is mainly distributed throughout Asia, Oceania and North America and is used as an important herbal medicine. H. japonicum contains many valuable secondary metabolites, such as flavonoids, phloroglucinols and xanthones and has hepatoprotective, anti-tumor, antibacterial, antiviral, and antioxidant activities and effects on the cardiovascular system and immunity. Coupled with phytochemical and pharmacological research, a series of analytical methods have been developed to evaluate the quality of H. japonicum based on its bioactive components. A pharmacokinetics study involved the absorption of two main flavonoids of H. japonicum in rats. This review aims to present an up-to-date and comprehensive overview of the phytochemistry, pharmacology, quality control and pharmacokinetics of H. japonicum, which should be useful for the greater development of H. japonicum, especially in the development of new drugs and therapeutics for various diseases.

Abstract
Background. Researchers focused on developing traditional therapies as pharmacological medicines to treat liver cirrhosis. Objectives. Evaluating the hepatoprotective activity of Boesenbergia rotunda (BR) rhizome ethanolic extract on thioacetamide-induced liver cirrhosis in rats. Methods. Male Sprague-Dawley rats were intraperitoneally injected with 200 mg/kg TAA 3 times/week and daily oral administration of 250 mg/kg, 500 mg/kg of BR extract, and 50 mg/kg of the reference drug Silymarin for 8 weeks. At the end of the experiment, Masson's trichrome staining was used to measure the degree of liver fibrosis. Hepatic antioxidant enzymes (CAT and GPx), nitrotyrosine, cytochrome (P450 2E1), matrix metalloproteinase (MMP-2 and MMP-9), tissue inhibitor of metalloproteinase (TIMP-1), and urinary 8-hydroxyguanosine were measured. Serum levels of transforming growth factor TGF-β1, nuclear transcription factor NF-κB, proinflammatory cytokine IL-6, and caspase-3 were evaluated. Serum protein expression and immunohistochemistry of proapoptotic Bax and antiapoptotic Bcl-2 proteins were measured and confirmed by immunohistochemistry of Bax, Bcl-2, and proliferating cell nuclear antigen (PCNA). Results. BR treatment improved liver histopathology, immunohistochemistry, and biochemistry, triggered apoptosis, and inhibited cytokines, extracellular matrix proteins, and hepatocytes proliferation. Conclusion. Liver cirrhosis progression can be inhibited by the antioxidant and anti-inflammatory activities of BR ethanolic extract while preserving the normal liver status.

Quercetin 7-rhamnoside (Q7R) is one of the main flavonoid components of Hypericum japonicum. However, whether Q7R is one of the active ingredients responsible for the hepatopreventive effects of Hypericum japonicum has not yet been ascertained. Thus, the aim of the present study was to elucidate whether Q7R attenuates apoptosis induced by glycochenodeoxycholic acid (GCDC) in vitro, and to elucidate the mechanisms involved. L-02 human normal liver cells were pre-incubated with 0, 50, 100 and 200 µM Q7R for 30 min and then exposed to 100 µM GCDC for the indicated periods of time. Methylthiazolyldiphenyl-tetrazolium bromide (MTT) was performed to examine cell viability. Apoptosis was evaluated by Hoechst 33258 staining and Annexin V-FITC/PI double staining. Intracellular reactive oxygen species (ROS) were detected by flow cytometry using the oxidation-sensitive fluorescent probe, DCFH-DA. The assay for glutathione (GSH) was performed using a GSH detection kit. Intracellular Ca2+ concentration was evaluated using a confocal laser scanning microscope with Fluo-3 as the Ca2+ probe and mitochondrial membrane potential (Δψm) was measured by rhodamine 123 (Rh123) fluorescence. Q7R attenuated the GCDC-induced reduction in cell viability and the high apoptotic rate. Moreover, Q7R protected the L-02 cells from ROS overproduction, GSH depletion, intracellular Ca2+ accumulation and Δψm decrease induced by GCDC. These results suggest that Q7R attenuates L-02 cell injury induced by GCDC, possibly by inhibiting the overproduction of ROS, GSH depletion, intracellular Ca2+ accumulation and Δψm decrease, thereby minimizing L-02 cell apoptosis.

Hepatoprotective Activity of the Total Saponins from Actinidia valvata Dunn Root against Carbon Tetrachloride-Induced Liver Damage in Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:216061. [PMID: 23243434 PMCID: PMC3518303 DOI: 10.1155/2012/216061] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2012] [Revised: 09/27/2012] [Accepted: 10/04/2012] [Indexed: 01/12/2023]
Abstract
The protective activity of the total saponins from Actinidia valvata Dunn root (TSAV) was studied against carbon-tetrachloride- (CCl4-) induced acute liver injury in mice. Mice were orally administered TSAV (50, 100, and 200 mg/kg) for five days and then given CCl4. TSAV pretreatment significantly prevented the CCl4-induced hepatic damage as indicated by the serum marker enzymes (AST, ALT, and ALP). Parallel to these changes, TSAV also prevented CCl4-induced oxidative stress by inhibiting lipid peroxidation (MDA) and restoring the levels of antioxidant enzymes (SOD, CAT, GR, and GPX), GSH and GSSG. In addition, TSAV attenuated the serum TNF-α and IL-6 levels and inhibited the serum iNOS and NO levels. Liver histopathology indicated that TSAV alleviated CCl4-induced inflammatory infiltration and focal necrosis. TSAV (200 mg/kg) also significantly decreased Bak, Bax mRNA and Fas, FasL, p53, and NF-κB p65 protein expressions and increased Bcl-2 mRNA and protein expressions. Meanwhile, TSAV significantly downregulated caspase-3 and caspase-8 activities and prevented CCl4-induced hepatic cell apoptosis. In addition, TSAV exhibited antioxidant activity through scavenging hydroxyl and DPPH free radicals in vitro. These results indicated that TSAV could protect mice against CCl4-induced acute liver damage possibly through antioxidant, anti-inflammatory activities and regulating apoptotic-related genes.

Abstract
Background. Experimental research in hepatology has focused on developing traditional medicines into potential pharmacological solutions aimed at protecting liver from cirrhosis. Along the same line, this study investigated the effects of ethanol-based extract from a traditional medicine plant Boesenbergia rotunda (BR) on liver cirrhosis. Methodology/Results. The BR extract was tested for toxicity on 3 groups of rats subjected to vehicle (10% Tween 20, 5 mL/kg) and 2g/kg and 5g/kg doses of the extract, respectively. Next, experiments were conducted on a rat model of cirrhosis induced by thioacetamide injection. The rats were divided into five groups and, respectively, administered orally with 10% Tween-20 (5 mL/kg) (normal control group), 10% Tween-20 (5 mL/kg) (cirrhosis control group), 50 mg/kg of silymarin (reference control group), and 250 mg/kg and 500 mg/kg of BR extract (experimental groups) daily for 8 weeks. The rats in normal group were intraperitoneally injected with sterile distilled water (1 mL/kg) 3 times/week, and those in the remaining groups were injected intraperitoneally with thioacetamide (200 mg/kg) thrice weekly. At the end of the 8 weeks, the animals were sacrificed and samples were collected for comprehensive histopathological, coagulation profile and biochemical evaluations. Also, the antioxidant activity of the BR extract was determined and compared with that of silymarin. Data from the acute toxicity tests showed that the extract was safe to use. Histological analysis of the livers of the rats in cirrhosis control group revealed uniform coarse granules on their surfaces, hepatocytic necrosis, and lymphocytes infiltration. But, the surfaces morphologically looked much smoother and the cell damage was much lesser in those livers from the normal control, silymarin and BR-treated groups. In the high-dose BR treatment group, the livers of the rats exhibited nearly normal looking lobular architecture, minimal inflammation, and minimal hepatocyte damage, the levels of the serum biomarkers and liver enzymes read nearly normal, and these results were all comparable to those observed or quantified from the normal and silymarin-treated groups. The BR extract had the antioxidant activity about half of what was recorded for silymarin. Conclusion. The progression of the liver cirrhosis can be intervened using the ethanol-based BR extract, and the liver's status quo of property, structure, and function can be preserved. This capability of the extract warrants further studies exploring the significance of its pharmacologic potential in successfully treating the liver cirrhosis in humans.

Abstract
The mechanisms of the ameliorating effects of dioscin against CCl(4) induced acute liver damage are investigated in this study. Dioscin significantly inhibited (p<0.01) the increases of serum ALT and AST activities compared with the CCl(4)-treated animals. The hepatic lipid peroxidation formation and, concentrations of TNF-α and IL-6 were also decreased. Liver histopathologic studies and a DNA laddering assay indicated that dioscin protected hepatocytes against CCl(4)-induced apoptosis and necrosis. Furthermore, dioscin decreased the protein expressions of Fas/FasL, increased Bcl-2/Bax ratio, inhibited the release of cytochrome c from mitochondrion to cytosol and attenuated CCl(4)-induced caspase-3 and -8 activities. The expressions of ICAM-1, vimentin, prohibitin, HGF, c-MET and GSTA1 were also regulated by dioscin and iNOS was also involved in the effects of this agent. These protective effects against CCl(4) induced acute liver damage might be through inhibiting lipid peroxidation, inflammatory cytokines, necrosis and apoptosis, and dioscin shows promise for development toward the treatment of acute chemically mediated liver injury.

Abstract
BACKGROUND AND PURPOSE Hyperbilirubinaemia and cholestasis are two major forms of liver abnormality. The Chinese herb Yin Chin has been used for thousands of years to treat liver dysfunctions. In mice, this herb and its principal ingredient scoparone were found to accelerate the clearance of bilirubin accompanied by the induction of uridine diphosphate-5'-glucuronosyltransferase-1A1 (UGT1A1), a bilirubin processing enzyme. The aim of this study was to determine whether scoparone induces the expression of human UGT1A1. In addition, the expression of the bile salt export pump (BSEP), a transporter of bile acids, was determined. EXPERIMENTAL APPROACH Primary human hepatocytes and hepatoma line Huh7 were treated with scoparone, chenodeoxycholic acid (CDCA) or both. The expression of UGT1A1 and BSEP mRNA was determined. The activation of the human BSEP promoter reporter by scoparone was determined in Huh7 cells by transient transfection and in mice by bioluminescent imaging. The metabolism of scoparone was investigated by recombinant CYP enzymes and pooled human liver microsomes. KEY RESULTS Scoparone did not enhance the expression of either human BSEP or, surprisingly, UGT1A1. However, scoparone significantly potentiated the expression of BSEP induced by CDCA. Consistent with this, scoparone potentiated the stimulant effect of CDCA on the human BSEP promoter. This potentiation was enhanced by co-transfection of cytochrome P4501A2 but abolished by the PKC inhibitor GF109203X. CONCLUSIONS AND IMPLICATIONS Scoparone and Yin Chin normalize liver function primarily by enhancing the secretion of bile acids, and this effect probably varies depending on the metabolic rate of scoparone.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The leaf decoction of Byrsocarpus coccineus (Connaraceae) is drunk for the treatment of jaundice in West African traditional medicine. AIM OF THE STUDY To investigate the hepatoprotective and in vivo antioxidant effects of Byrsocarpus coccineus in carbon tetrachloride (CCl(4))-induced hepatotoxicity in rats. MATERIALS AND METHODS Group allotment in this study included vehicle, CCl(4), Byrsocarpus coccineus 1000 mg/kg alone, Byrsocarpus coccineus 200, 400, and 1000 mg/kg+CCl(4) and Livolin((R)) 20mg/kg+CCl(4), and treatment was carried out accordingly. On the 7th day, rats were sacrificed and blood was withdrawn by cardiac puncture. The levels and activities of serum biochemical parameters and antioxidant enzymes were then assayed using standard procedures. RESULTS CCl(4) significantly (P<0.05) increased the levels of ALT and AST and reduced total protein. In CCl(4) treated animals, Byrsocarpus coccineus (200, 400, and 1000 mg/kg) dose-dependently and significantly decreased ALT, AST and ALP levels with peak effect produced at the highest dose. Conversely, Byrsocarpus coccineus produced significant increases in albumin and total protein levels. The standard drug produced significant effects in respect of ALT (downward arrow), albumin (upward arrow), and total protein (upward arrow). CCl(4) also produced significant (P<0.05) reductions in the activity of catalase, SOD, peroxidase and GSH, and conversely increased MDA level. Byrsocarpus coccineus produced significant and dose-dependent reversal of CCl(4)-diminished activity of the antioxidant enzymes and reduced CCl(4)-elevated level of MDA. The standard drug also significantly increased CCl(4)-diminished antioxidant enzymes activity and reduced CCl(4)-elevated MDA level. In general, the effects of the standard drug were comparable and not significantly different from those of Byrsocarpus coccineus. CONCLUSION The results obtained in this study suggest that the aqueous leaf extract of Byrsocarpus coccineus possesses hepatoprotective and in vivo antioxidant effects. This finding justifies the use of this preparation in West African traditional medicine for the treatment of liver disease.

Abstract
This study determined whether cow or goat yogurt administration has a preventive effect on the hepatic damage undergone during an acute liver injury. Acute liver injury was induced by an intraperitoneal injection of d-galactosamine. Groups of mice were fed with cow or goat yogurt for 2 days or 7 days before the d-galactosamine injection. Blood and liver samples were obtained 12 hours after d-galactosamine inoculation. d-Galactosamine induced an increase in serum amino-transaminases, a reduction in the number of blood leukocytes, an enhancement in neutrophil myeloperoxidase activity, a recruitment of leukocytes toward the liver, an increase in cell death, and an alteration in prothrombin time, activated partial thromboplastin time, and fibrinogen levels. Treatment with cow or goat yogurt was effective at increasing leukocyte number and decrease myeloperoxidase activity. We also observed a decrease in leukocyte accumulation in the liver and a reduction in cell death. Activated partial thromboplastin time and fibrinogen were normalized, but prothrombin time only showed an improvement without reaching normal values. Cow or goat yogurts were effective at protecting against an experimental acute liver injury, especially when administered for 7 days.

Abstract
AIM OF THE STUDY Various species of Hypericum genus have been used in the Canary Islands as sedative, diuretic, vermifuge, wound healing, antihysteric and antidepressant agent. Studies have shown that methanol extract of Hypericum grandifolium Choisy is active in tetrabenazine-induced ptosis and forced swimming tests. In the current study, the aqueous, butanol and chloroform fractions obtained from the methanol extract as well as three sub-fractions derived from the chloroform fraction were evaluated for their central nervous effects in mice, particularly their antidepressant activity. MATERIALS AND METHODS The central nervous effect of different fractions and sub-fractions of Hypericum grandifolium was evaluated in mice using various behavioural models including locomotor and muscle relaxant activity, forced swimming test, effect on normal body temperature, barbiturate-induced sleep, tetrabenazine-induced syndrome and 5-hydroxytryptohan-induced head twitches and syndrome. RESULTS We found that the butanol and chloroform fractions and all sub-fractions showed an antidepressant effect in the forced swimming test, the chloroform fraction being the most active. They produced no effects or only a slight depression of locomotor activity. Chloroform fraction significantly increased the pentobarbital-induced sleeping time, produced a slight but significant hypothermia and antagonized tetrabenazine-induced ptosis, whereas the butanol fraction produced a slight potentiation of 5-HTP-induced head twitches and syndrome. CONCLUSIONS The present results, together with previous pharmacological and phytochemical data, indicated that Hypericum grandifolium possess antidepressant-like effects in mice and that different constituents, such as the flavonoids and the benzophenone derivatives, could be responsible at least in part for the antidepressant effects observed for this species.
