Inflammatory Effect

Dipterocarpus tuberculatus Roxb. has been used traditionally as a remedy for many diseases, especially inflammation. Therefore, we analyzed and explored the mechanism of the anti-inflammatory effect of a Dipterocarpus tuberculatus Roxb. ethanol extract (Dt-EE). Dt-EE clearly and dose-dependently inhibited the expression of pro-inflammatory cytokines such as IL-6, TNF-α, and IL-1β in lipopolysaccharide (LPS)-treated RAW264.7 cells. Also, Dt-EE suppressed the activation of the MyD88/TRIF-mediated AP-1 pathway and the AP-1 pathway related proteins JNK2, MKK4/7, and TAK1, which occurred as a result of inhibiting the kinase activity of IRAK1 and IRAK4, the most upstream factors of the AP-1 pathway. Finally, Dt-EE displayed hepatoprotective activity in a mouse model of hepatitis induced with LPS/D-galactosamine (D-GalN) through decreasing the serum levels of alanine aminotransferase and suppressing the activation of JNK and IRAK1. Therefore, our results strongly suggest that Dt-EE could be a candidate anti-inflammatory herbal medicine with IRAK1/AP-1 inhibitory and hepatoprotective properties.

Abstract Background The objective of the study is to evaluate the hepatoprotective activity of methanolic extract fractions of Lindernia ciliata (LC) and development of qualitative analytical profile of the bioactive fraction using HPLC fingerprinting analysis. All the fractions of methanolic extract of Lindernia ciliata (LCME) are assessed for their total phenolic, flavonoid contents and in vitro antioxidant properties by using DPPH, superoxide, nitric oxide, hydroxyl radical scavenging activities and reducing power assay. Acute toxicity study was conducted for all the fractions and the two test doses 50 and 100 mg/kg were selected for the hepatoprotective study. Liver damage was induced in different groups of rats by administering 3 g/kg.b.w.p.o. paracetamol and the effect of fractions were tested for hepatoprotective potential by evaluating serum biochemical parameters and histology of liver of rats. The effective fraction was evaluated for its antihepatotoxic activity against D-Galactosamine (400 mg/kg b.w. i.p.) and in vivo antioxidant parameters viz., Glutathione (GSH), Melondialdehyde (MDA) and Catalase (CAT) levels are estimated using liver homogenate. Results Among all the fractions, butanone fraction of LCME, (BNF-LCME) has shown better hepatoprotective activity and hence it is selected to evaluate the antihepatotoxicity against D-GaIN. The activity of BNF-LCME is well supported in in vitro and in vivo antioxidant studies and may be attributed to flavonoidal, phenolic compounds present in the fraction. Hence, BNF-LCME was subjected to the development of qualitative analytical profile using HPLC finger printing analysis. Conclusions All the fractions of LCME exhibited significant hepatoprotective activity and BNF-LCME (50 mg/kg) was identified as the most effective fraction.

ABSTRACT: The study is designed for the evaluation of in-vivo Hepato protective and in-vitro Anti oxidant activity of ethanol extracts from the bark of Shorea robusta (Dipterocarpaceae) by CCl4 induced hepatotoxicity in rats. Ethanol extracts from the bark Shorea robusta (EESR) was evaluated for hepatoprotective activity in rats by inducing liver damage by CCl4. The anti oxidant activity of EESR was assayed by various in-vitro antioxidant methods and activities were compared to standard ascorbic acid. Ethanol extracts at an oral dose 200mg/kg and 400mg/kg exhibited a significant (*p<0.005) protective effects by lowering the level of SGOT, SGPT, ALP, Serum bilirubin, total cholesterol and increasing the level of total proteins as compared to Silymarin (50mg/kg) used as positive control. The extracts exhibit significant anti oxidant activity in various in vitro anti oxidant models.  From these studies we are concluding that, the ethanolic extracts of S.robusta have potent hepatoprotective effects and have anti oxidant properties, hence can be used as a natural product against liver damage.KEY WORDS: Anti oxidant, Carbon tetra chloride,  Hepatoprotective,  Shorea robusta

In vitro antioxidant and in vivo hepatoprotective activities of Cleome gynandra ethanolic leaf and root extracts were assessed. In vitro antioxidant activity was carried by DPPH, Nitric oxide, hydroxyl radical and phosphomolybdenum assays. Hepatoprotective activity was evaluated by Carbon tetrachloride (CCl4) induced hepatotoxicity in albino rats.The animals were divided into seven groups (Four test groups - Ethanolic Leaf and Root Extracts of Cleome gynandra of 100 mg/kg and 200 mg/kg, standard silymarin (100 mg/kg), toxic control-carbon tetrachloride and vehicle). On the eight day, the blood was collected and parameters like serum glutamic oxaloacetic transaminase (SGOT), Serum glutamic pyruvic transaminase (SGPT), Alkaline phosphatase (ALP) and Total bilirubin (TB) were estimated. Significant antioxidant status with good IC50 values similar to standard ascorbic acid was obtained. A significant decrease in liver enzymes was observed in test groups comparable to silymarin. From the results obtained, ethanolic leaf extract has contributed better hepatoprotection compared with root extract in experimental rats.

LC-ESI-MS (Liquid Chromatography coupled with Electrospray Ionization Mass Spectrometry profiling of a methanol extract from Buddleia indica (BIM) leaves revealed 12 main peaks in which verbascoside and buddlenoid B represent the major compounds. The antioxidant and hepatoprotective activities of BIM were investigated using different in vitro and in vivo experimental models. BIM exhibited substantial in vitro antioxidant properties in DPPH· and HepG2 assays. Regarding CCl4 (carbon tetrachloride) induced hepatotoxicity in a rat model, oxidative stress markers became significantly ameliorated after oral administration of BIM. Lipid peroxide levels showed a 51.85% decline relative to CCl4-treated rats. Super oxide dismutase (SOD), total antioxidant status (TAS), and catalase (CAT) revealed a marked increase by 132.48%, 187.18%, and 114.94% relative to the CCl4 group. In a tamoxifen-induced hepatotoxicity model, BIM showed a considerable alleviation in liver stress markers manifested by a 46.06% and 40% decline in ALT (Alanine Transaminase) and AST (Aspartate Transaminase) respectively. Thiobarbituric acid reactive substances (TBARS) were reduced by 28.57% and the tumor necrosis factor alpha (TNF-α) level by 50%. A virtual screening of major secondary metabolites of BIM to TNF-alpha employing the C-docker protocol showed that gmelinoside H caused the most potent TNF- α inhibition as indicated from their high fitting scores. Thus, BIM exhibited a potent hepatoprotective activity owing to its richness in antioxidant metabolites.

Abstract An ultra-high-performance liquid chromatography-high-resolution mass spectrometry based profiling of a purified MeOH extract (PME) from the roots of Chenopodium bonus-henricus L. (Amaranthaceae) tentatively identified 15 saponins of six sapogenins. The PME exerts hepatoprotective and antioxidant activities comparable to those of flavonoid complex silymarin in in vitro (1 and 10 μg/mL) and in vivo (200 mg/kg/daily for 7 days) models of hepatotoxicity, induced by CCl4. The main constituents of PME, respectively saponins bonushenricoside A (1), 3-O-β-D-glucuronopyranosyl-bayogenin-28-O-β-D-glucopyranosyl ester (2), 3-O-β-D-glucuronopyranosyl-medicagenic acid-28-O-β-D-xylopyranosyl (1→4)-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranosyl ester (3), 3-O-β-D-glucuronopyranosyl-2β-hydroxygypsogenin-28-O-β-D-glucopyranosyl ester (4), 3-O-α-L-rabinopyranosyl-bayogenin-28-O-β-D-glucopyranosyl ester (6) and bonushenricoside B (8) (3 μg/mL each), compared to silymarin (5 and 50 μg/mL), significantly reduced the cellular damage caused by CCl4 in rat hepatocytes, preserved cell viability and glutathione level, decreased lactate dehydrogenase leakage and reduced lipid damage. The experimental data suggest that the glycosides of phytolaccagenin, bayogenin, medicagenic acid, 2β-hydroxygypsogenin, 2β-hydroxyoleanoic acid and oleanoic acid are a promising and safe class of hepatoprotective agents.

Sesame (Sesamum indicum L.) seeds have been authenticated for its medicinal value in both Chinese and Indian systems of medicine. Its numerous potential nutritional benefits are attributed to its main bioactive constituents, sesamol. As a result of those studies, several molecular mechanisms are emerging describing the pleiotropic biological effects of sesamol. This review summarized the most interesting in vitro and in vivo studies on the biological effects of sesamol. The present work summarises data available from Pubmed and Scopus database. Several molecular mechanisms have been elucidated describing the pleiotropic biological effects of sesamol. Its major therapeutic effects have been elicited in managing oxidative and inflammatory conditions, metabolic syndrome and mood disorders. Further, compelling evidence reflected the ability of sesamol in inhibiting proliferation of the inflammatory cell, prevention of invasion and angiogenesis via affecting multiple molecular targets and downstream mechanisms. Sesamol is a safe, non‐toxic chemical that mediates anti‐inflammatory effects by down‐regulating the transcription of inflammatory markers such as cytokines, redox status, protein kinases, and enzymes that promote inflammation. In addition, sesamol also induces apoptosis in cancer cells via mitochondrial and receptor‐mediated pathways, as well as activation of caspase cascades. In the present review, several pharmacological effects of sesamol are summarised namely, antioxidant, anti-cancer, neuroprotective, cardioprotective, anti-inflammatory, hypolipidemic, radioprotective, anti-aging, anti-ulcer, anti-dementia, anti-depressant, antiplatelet, anticonvulsant, anti-anxiolytic, wound healing, cosmetic (skin whitening), anti-microbial, matrix metalloproteinase (MMPs) inhibition, hepatoprotective activity and other biological effects. Here we have summarized the proposed mechanism behind these pharmacological effects.

Ziziphus rugosa Lam. belongs to the family Rhamnaceae and is found chiefly in deciduous and semi evergreen forest of Western Ghats. The present research was undertaken to establish in vitro antioxidant and in vivo hepatoprotective activity of ethanolic extract of Z.rugosa Lam. leaves. The powdered leaves of Z. rugosa were extracted with ethanol and preliminary phytochemical screening was performed for the presence of various phytoconstituents. DPPH assay and β-glucuronidase inhibition assay were selected for the free radical scavenging activity. For the assessment of hepatoprotective activity, alcohol and CCl4 induced hepatotoxicity model were used. The phytochemical analysis of ethanolic extract showed the presence of alkaloids, saponins and flavonoids. The extract exhibited concentration dependent radical scavenging activity with an IC50 value of 61.88 μg/ml and β –glucoronidase inhibition activity with an IC50 value of 70.61 μg/ml. It was speculated that the Z. rugosa Lam. ethanolic extract shows dosedependent hepatoprotective activity which is equivalent with the standard drug Silymarin. The inhibition of free radicals or free radical scavenging activity is significant in the protection against CCl4 and alcohol induced hepatopathy. Hence, it is likely that the antioxidant activity of ethanolic extract of Z. rugosa Lam. might contribute to the hepatoprotective action.
