In vitro anti-inflammatory and antimicrobial potential of leaf extract from Artemisia nilagirica (Clarke) Pamp

In the present investigation, the bioactive compounds from the leaf extract of Artemisia nilagirica showed potent anti-inflammatory and antimicrobial activity. The leaf extract showed a maximum protection of human red blood cells (HRBC) with 74.63% at 20?µg/mL concentration, and the minimum hemolysis was 25.37% in a hypotonic solution with diclofenac as the control. The in vitro antimicrobial activity of plant extract against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella typhi, Proteus vulgaris, Yersinia enterocolitica, Bacillus subtilis, and Candida albicans was evaluated at various concentrations (50, 100, 150, and 200?µg). The maximum zone of inhibition was observed against P. aeruginosa followed by B. subtilis, S. typhi, S. aureus and E. coli. The leaf extract also showed potent activity against C. albicans.     

Quantification of biochemical compounds in Bauhinia Variegata Linn flower extract and its hepatoprotective effect

Liver disorders may occur as a result of exposure to chemical compounds capable of inducing the oxidative stress and hepatic injuries. The aim of present study was to investigate the effects of flower extracts of B. Variegata for the treatment of liver injury induced by the CCl₄. About 1 ml/kg body weight (b.w) of CCl4 was induced to experimental mice by intraperitoneal way for 14 days. The methanol and chloroform extracts (100, 200 and 300 mg/kg b.w) were administered to experimental animals for 14 days along with standard drug Silymarine (100 mg/kg b.w). The extracts alone showed no evidence of hepatic toxicity but animals exposed to CCl₄ without the treatment with B. Variegata presented variations in levels of liver enzymes, antioxidant enzymes, proteins and blood cells as well as injuries in liver cells were also observed during histopathological study. However, after the treatments especially with 300 mg/kg b.w of methanol flower extracts levels of liver markers (ALT, AST and ALP), antioxidant enzymes and blood cells decreases and turned towards normal levels. Whereas level of total proteins and bilirubin was improved and damaged liver cells were repaired. The curative activity of flower extracts can be correlated to the higher potential of antioxidants and occurrence of Quercetin and some other organic compounds those were investigated from flower extracts of B. Variegata during HPLC and GC-MS analysis. The finding of this study supports the use of B. Variegata flower formulation in folk medicines.     

Biogenic proficient synthesis of (Au-NPs) via aqueous extract of Red Dragon Pulp and seed oil: Characterization,antioxidant, cytotoxic properties,anti-diabetic anti-inflammatory,anti-Alzheimer and their anti-proliferative potential against cancer cell lines

Gold nanoparticles with tiny sizes and biostability are particularly essential and are employed in a variety of biomedical applications. Using a reducing agent and a stabilising agent to make gold nanoparticles has been reported in a number of studies. Gold nanoparticles with a particle size of 25.31 nm were synthesized in this study utilising Hylocereus polyrhizus (Red Pitaya) extract, which functions as a reducing and stabilising agent. The extract of Red Pitaya is said to be a powerful antioxidant and anti-cancer agent. Because of its substantial blood biocompatibility and physiological stability, green production of gold nanoparticles with H. polyrhizus fruit extract is an alternative to chemical synthesis and useful for biological and medical applications. The formation and size distribution of gold nanoparticles were confirmed by HPLC, UV-Vis spectrophotometer, X-ray diffraction (XRD), Dynamic light scattering (DLS), Zeta potential, Transmission electron microscopy (TEM), Fourier transformed infrared spectroscopy (FTIR), Energy dispersive X-ray (EDX) and X-ray photoelectron spectroscopy (XPS). The well-analysed NPs were used in various biological assays, including anti-diabetic, anti-inflammatory, anti-Alzheimer, and antioxidant (DPPH), and cytotoxic investigations. The NPs also showed a dose-dependent cytotoxic activity against HCT-116, HepG2 and MCF-7 cell lines, with IC₅₀ of 100 µg/mL for HCT-116 cells, 155 µg/mL for HepG2, and for MCF-7 cells the value was 165 µg/mL respectively. Finally, the outstanding biocompatibility of Au-NPs has led to the conclusion that they are a promising choice for various biological applications.     

Synthesis and biological evaluation of thiazolidine-2,4-dione-pyrazole conjugates as antidiabetic,anti-inflammatory and antioxidant agents

A series of fourteen novel thiazolidine-2,4-dione derivatives clubbed with pyrazole moiety were synthesized via four step reaction procedure. Reactions were monitored by thin layer chromatography and were characterized by physicochemical and spectrophotometric (IR, Mass, ¹HNMR and ¹³CNMR) analysis. The spectral data were in good agreement with their structures. The title compounds were docked against peroxisome proliferated activated receptors (PPAR-γ) and alpha-amylase and further evaluated for in vivo and in vitro antidiabetic, in vitro anti-inflammatory and antioxidant activities. Compound GB14 exhibited significant blood glucose lowering activity and was also found to be active inhibitor of alpha-amylase. Compound GB7 was found to be potent anti-inflammatory agent in terms of reducing inflammatory markers (TNF-α, IL-β, MDA) and also showed antioxidant activity to good extent. Therefore, these compounds may be considered as promising candidates for the development of new antidiabetic agents.     

The anti-inflammatory properties of the methanolic extract of Cucumis melo Linn. against prostate enlargement in Wistar rats

In different parts of the world, Cucumis melo Linn. (C melo) is used for its medicinal properties. The present study examined the effects of a methanolic extract of C melo Linn. (F1 hybrid, MECM) on benign prostatic hyperplasia in adult male Wistar rats and evaluated its anti-inflammatory activity in vivo. MECM treatment reduced prostate weight mildly. Histopathological studies showed that the extract produced a strong protective effect against the development of BPH by testosterone. The MECM also showed protection from testosterone-induced benign prostatic hyperplasia (BPH). MECM was tested against carrageenan-induced inflammation in rats' paws to determine its anti-inflammatory activity. It was shown that MECM had a pronounced effect on the inflammatory response in the late phase, i.e., one hour after carrageenan injection. Prostaglandins and nitric oxide are primarily responsible for this phase indicating that MECM can modify the production and release of prostaglandin and nitric oxide. A novel formulation containing C melo may be able to treat the conditions mentioned above.     

Role of membranes on the antibacterial and anti-inflammatory activities of the bioactive compounds from Hypoxis rooperi corm extract

Hypoxis rooperi corm extract (‘African potato’) is known for its traditional and ethnomedical uses in the treatment of a large variety of diseases. Its main bioactive compound hypoxoside (HYP) and its aglycone derivative rooperol (RO) were isolated and the interaction of these compounds with several types of model membranes was studied in order to contribute to the understanding of their molecular mechanism. The results show that RO abolishes the main transition phase and perturb the van der Waals interactions between phospholipid acyl chains in a stronger way than HYP in dimiristoylphosphatidylcholine (DMPC), dielaidoylphosphatidylethanolamine (DEPE) and dimiristoylphosphatidylglycerol membranes (DMPG), probably indicating that this molecule inserts into the bilayer. This effect decreases as the acyl chain length of the phospholipid increases. RO also promoted the formation of hexagonal H_II phases at lower temperatures compared to pure DEPE. On the contrary, HYP showed a shallow interaction with phospholipids. This compound promoted the formation of gel-fluid like intermediate structures with isotropic motion in phosphatidylglycerol membranes at physiological pH, and affected the phospholipid/water interface probably through the variation of the surface charge of the phospholipid phosphate groups. Moreover, RO inhibited Staphylococcus aureus in a stronger manner than Escherichia coli and promoted a higher leakage level in E. coli, PG and PE-containing synthetic membranes. Furthermore, RO showed a significant degree of inhibition of cyclooxygenase-2 (COX-2) and cyclooxygenase-1 (COX-1) evidencing an approximate COX-2/COX-1 IC₅₀ ratio of 1.9, therefore this compound may be responsible for the anti-inflammatory activity of H. rooperi corm extract. These results may contribute to understand the molecular mechanism of the antibacterial and/or anti-inflammatory properties of the bioactive compounds deriving from the African potato corm extract.     

Two new metabolites from Portulaca oleracea and their anti-inflammatory activities

Two new metabolites, identified as 6-phenylbenzofuran-4-ol, named olerabenzofuran (1), and 2-(furan-2-yl)− 6-hydroxy-1 H-inden-1-one, named oleraindenone (2), together with eight furan compounds obtained for the first time, (+)-pinoresinol (3), (-)-syringaresinol (4), (+)-diasyringaresinol (5), (+)-episyringaresinol (6), (2 S)− 1-[2-(furan-2-yl)− 2-oxoethyl]− 5-oxopyrrolidine-2-carboxylic acid (7), methyl (2 S)− 1[2-(furan-2-yl)− 2-oxoethyl]− 5-oxopyrrolidine-2-carboxylate (8), drynaran (9), and 2-furoic acid (10), were isolated from Portulaca oleracea L., and spectroscopic methods, including 1D and ²D NMR and UHPLC-ESI-QTOF/MS spectrometry techniques, were employed to determine their structures. It was suggested that both olerabenzofuran (1) and oleraindenone (2) could significantly inhibit inflammatory factor interleukin-1β (IL-1β) in RAW 264.7 cells induced by LPS.     

Adaptive changes in photosynthetic performance and secondary metabolites during white dead nettle micropropagation

The white dead nettle, Lamium album L., is an herb that has been successfully cultivated under in vitro conditions. The L. album micropropagation system offers a combination of factors (light intensity, temperature, carbon dioxide (CO₂) level, humidity) that are limiting for plant growth and bioactive capacity. To get a better understanding of the mechanism of plant acclimation towards environmental changes, we performed a comparative investigation on primary and secondary metabolism in fully expanded L. album leaves during the consecutive growth in in situ, in vitro, and ex vitro conditions. Although the genetic identity was not affected, structural and physiological deviations were observed, and the level of bioactive compounds was modified. During in vitro cultivation, the L. album leaves became thinner with unaffected overall leaf organization, but with a reduced number of palisade mesophyll layers. Structural deviation of the thylakoid membrane system was detected. In addition, the photosystem 2 (PS2) electron transport was retarded, and the plants were more vulnerable to light damage as indicated by the decreased photoprotection ability estimated by fluorescence parameters. The related CO₂ assimilation and transpiration rates were subsequently reduced, as were the content of essential oils and phenolics. Transfer of the plants ex vitro did not increase the number of palisade numbers, but the chloroplast structure and PS2 functionality were recovered. Strikingly, the rates of CO₂ assimilation and transpiration were increased compared to in situ control plants. While the phenolics content reached normal levels during ex vitro growth, the essential oils remained low. Overall, our study broadens the understanding about the nature of plant responses towards environmental conditions.     

Conventional and microwave assisted synthesis of pyrazolone Mannich bases possessing anti-inflammatory,analgesic, ulcerogenic effect and antimicrobial properties

Microwave assisted reactions showed that require shorter reaction time and good yield. The newly synthesized compounds were screened for their anti-inflammatory, analgesic activity, antioxidant, and antibacterial effects were compared with standard drug. Among the compounds studied, compound (4f) showing nearly equipotent anti-inflammatory and analgesic activity than the standard drug (indomethacin), along with minimum ulcerogenic index. Compounds (4b and 4i) showing 1.06 times more active than ciprofloxacin against tested Gram-negative bacteria.     

Antioxidant,hepatoprotective and cytotoxic effects of icetexanes isolated from stem-bark of Premna tomentosa

The study investigates the antioxidant, hepatoprotective and antiproliferative effects of novel icetexane diterpenoids (ice 1–4) isolated from hexane extract of stem bark of Premna tomentosa. A549, HT-29, MCF-7, MDA-MB-231, A431 cells were used to assess the antiproliferative activity by MTT assay. Cell death induced by apoptosis was determined by morphological assessment studies using acridine orange/ethidium bromide staining (dual staining), mitochondrial potential measurement by JC-1 staining, and cell cycle analysis by propidium iodide staining method by Muse cell analyser. Anti oxidant activity was investigated by in vitro assays such as DPPH, nitric oxide and superoxide scavenging activities. Hepatoprotective activity was determined in vitro with HepG2 cells and in vivo by tBHP induced hepatic damage mice model. Based on the in vitro cytotoxic assays and morphological assessment studies using fluorescence microscopic study (acridine orange and ethidium bromide double staining) and mitochondrial potential measurements, it was found that ice 2 and 3 possess good antiproliferative effect via mitochondrial mediated apoptosis in human lung and breast cancer cells. Results of in vitro antioxidant studies demonstrated that ice-4 has showed good antioxidant activity. The restoration of serum levels of SGOT, SGPT and ALKP, liver GSH status and reduction or inhibition of lipid peroxidation in liver of tBHP intoxicated mice after administration of ice-4 at dose of 250 mg/kg indicated its potential use for hepatoprotective activity.     

Biophysical and biochemical characterization of active secondary metabolites from Aspergillus allahabadii

Fungal secondary metabolites are a diverse group of natural chemical products with physiological relevance. We aimed to identify bioactive secondary metabolites from Aspergillus allahabadii. We used “activity-guided fractionation” strategy for the isolation of secondary metabolites. Crude extracts showed good antibacterial activity. Two antibacterial secondary metabolites have been isolated from the crude extract. Chemical characterization of these compounds was performed using biophysical techniques (FT-IR, NMR, and mass spectrometry). Structural characterization confirmed these to be pyrone derivatives: 3-hydroxy 2-methyl 4-pyrone and 5-hydroxy-2-(hydroxymethyl)-4H-pyrone. These bioactive pyrone derivatives have been identified as maltol and kojic acid. From our initial observations, we infer that these pyrone derivatives have potent antimicrobial, antioxidant, antidiabetic, and mosquito larvicidal activities and no cytotoxicity. These compounds could have potential therapeutic and biomedical applications, but further mechanistic studies using animal models are very much necessary.     

New iridoid glycosides from the fruits of Forsythia suspensa and their hepatoprotective activities

A novel iridoid glycoside trimer named forsydoitriside A (1) and five new iridoid glycosides (2–6) were isolated from the fruits of Forsythia suspensa together with two known compounds (7, 8). These new structures were elucidated by comprehensive spectroscopic data and the comparison of experimental and calculated electronic circular dichroism spectra. Compounds 1–8 were all assayed on acetaminophen-induced HepG2 cell damage. The results exhibited that compounds 2, 3, 5 and 6 possessed strong hepatoprotective activities against the damage in HepG2 cell.     

Antagonistic,Anti-oxidant,Anti-inflammatory and Anti-diabetic Probiotic Potential of Lactobacillus agilis Isolated From the Rhizosphere of the Medicinal Plants

Potential probiotic bacteria can be used as a biotherapeutic agent and a sustainable alternative to antibiotics, as an anti-oxidative, anti-inflammatory, and anti-diabetic agent without causing any serious side effects. Mostly human-friendly Lactic acid bacteria (LAB) have been isolated from the animal-human origin to be used as biotherapeutic agents or to produce useful metabolites (nutraceutical). However, less information is known about the role of medicinal plants associated LAB as biotherapeutic agents. The isolation of 115 human-friendly Lactobacillus strains was done from the rhizosphere of the medicinal plants Ocimum tenuiflorum, Azadirachta indica, Ficus carica. The obtained bacteria were then tested for their safe status before being using it for a beneficial purpose. Out of 115 strains, 29 (25%) were negative for blood hemolytic activities. Among these 29 isolates, three isolates did not show a breakdown of gelatin and were recognized as safe. Antibiotic resistance assay showed resistance of two of them against antibiotics discs of Streptomycin (10 µg), Ciprofloxacin (20 µg), Vancomycin (30 µg), Metronidazole (10 µg), Ampicillin (5 µg), Chloramphenicol (30 µg), Kanamycin (30 µg), Erythromycin (15 µg), Penicillin (10 µg) and Tetracycline (30 µg). The bacterial isolate (T-2) was found safe that was identified as Lactobacillus agilis by sequence analysis of 16 s rRNA gene and processed in vitro as an anti-bacterial, anti-oxidant, anti-diabetic, and anti-inflammatory agent. Free radical scavenging activities and inhibition of α-amylase activities for Lactobacillus agilis were found relative to standard drug values as 68% and 73% and 51.3% and 65.3%, respectively. The in-vitro anti-inflammatory assay showed 61.6% (Lactobacillus agilis) while showed 69% (aspirin) activity for denaturation albumin protein. The results suggested that Lactobacillus agilis can be used as a potential probiotic strain as well as can be used to produce nutraceuticals.     

Blepharisides A and B,new flavonol glycosides from Blepharis ciliaris growing in Saudi Arabia

Bio-guided fractionation of the total MeOH extract (TME) of the aerial parts of Blepharis ciliaris (L.) B.L. Burtt. (Acanthaceae) growing in Saudi Arabia was carried out to evaluate its hepatoprotective activity against CCl₄-induced hepatotoxicity in rats. Successive chromatographic separations of the potent hepatoprotective n-BuOH fraction afforded two new flavonol glycosides, blepharisides A (1) and B (2), along with quercetin 3-O-rutinoside (3). Their structures were established by UV, IR, 1D, 2D NMR, and HRESIMS spectral data, in addition to comparison with literature data. Co-treatment of CCl₄ hepatic injured rats with the total MeOH extract (TME) and its fractions significantly restored the hepatic marker enzymes and total bilirubin to near-normal values compared to silymarin (reference drug). The isolated compounds were evaluated for their antioxidant and anti-inflammatory activities. They displayed significant antioxidant activity (DPPH assay) in relation to propyl gallate (positive control) (% inhibition of 88.2, 87.9, and 74.2, respectively). Compounds 1 and 2 demonstrated anti-inflammatory effects in the carrageenin induced paw edema method at a dose of 10 mg/kg.     

Molecular docking of phenolic compounds and screening of antioxidant and antidiabetic potential of Moringa oleifera ethanolic leaves extract from Qassim region,Saudi Arabia

IntroductionOxidative stress is crucial in diabetic pathophysiology, hence the prerequisite of ingesting naturally derived antioxidants as a remedial target. This study investigates the naturally occurring antioxidant and antidiabetic potential of Moringa oleifera ethanolic leaves extract.MethodsMoringa oleifera leaves were macerated (MOLE) by using 70% ethanol. Physiochemical and phytochemical examinations of MOLE was assayed using standard methods. The antioxidant activity was analyzed by DPPH (1, 1-diphenyl-2-picrylhydrazil) radical scavenging assay. In vitro antidiabetic was analyzed by pancreatic α-amylase enzyme inhibitory assay. The molecular docking was performed using AutoDock Vina v1.1.2 in PyRx 30.8.ResultsEthanolic extraction of MOLE by maceration technique, 14 % yield. Loss on drying, foreign organic matters and total ash value of OLE showed 0.27 w/w, 0.8 % and 19 %, respectively. Phytochemical test on MOLE confirmed starch, carbohydrate, flavonoid, gum, glycoside, saponin, tannin, and phenol presences. The total phenolic and flavonoid contents of MOLE are 260 mg GAE/g and 755 mg RUE/g of extract. MOLE (IC 50 55.6 ± 0.18 µg/mL) showed functional DPPH scavenging assay comparable to ascorbic acid (IC 50 46.71 ± 0.24 µg/mL). In the alpha-amylase inhibitory activity, Acarbose showed an IC 50 value of 19.45 ± 0.26 µg/mL, while MOLE portrayed an IC 50 value of 27.54 ± 0.07 µg/mL. Docking studies revealed that most phenolic compounds found within MOLE have minimum docking scores and high binding affinity against Human pancreatic alpha-amylase.ConclusionsThe invitro and docking results suggest that MOLE has been a viable natural bioactive source and might be a great potential source for future antidiabetic medicine.     

Eco-friendly synthesis of silver nanoparticles from the whole plant of Cleome viscosa and evaluation of their characterization,antibacterial, antioxidant and antidiabetic properties

The current research is to develop an easy and eco-friendly method for the synthesis of three different concentrations of silver nanoparticles (1mMCvAgNPs, 2mMCvAgNPs and 3mMCvAgNPs) using aqueous whole plant extract of Cleome viscosa and to evaluate their antibacterial, antioxidant and antidiabetic properties. CvAgNPs were characterized by Using UV–vis spectrophotometer, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM) and transmission electron microscope (TEM). The formation of CvAgNPs was confirmed by the observation of band between 250 nm to 600 nm UV–vis spectrum. The crystalline structure of CvAgNPs with a face-centered cubic (FCC) was confirmed by XRD. The responsible phytochemicals for the reduction and capping material of CvAgNPs were observed with FT-IR. The SEM analysis confirmed the size and shapes of CvAgNPs. The CvAgNPs have shown the rich content of total phenolic and total flavonoid components. The CvAgNPs have shown significant antibacterial activity on multi drug resistance Gram-negative and Gram-positive bacteria and also have shown significant strong antioxidant activities (DPPH, ABTS, H₂O₂ scavenging, Phosphomolybdenum assay and reducing power). The inhibitory action of CvAgNPs on α-glucosidase and α-amylase was stronger than the inhibitory action of acarbose. To best of our knowledge, this is the first attempt on the synthesis of AgNPs using C. viscosa whole plant aqueous extract. The synthesized CvAgNPs exhibited good antimicrobial, antioxidant and antidiabetic properties. Hence, to validate our results, the in vivo studies at the molecular level are needed to develop Cleome viscosa as an antibacterial, antioxidant and anti-diabetic agent.     

In vitro and in silico elucidation of antidiabetic and anti-inflammatory activities of bioactive compounds from Momordica charantia L.

Bitter melon (Momordica charantia) has been used to manage diabetes and related conditions in various parts of the world. In the present study, ten compounds were isolated from acetone and methanol extracts of bitter melon. The chemical structures of compounds were unambiguously elucidated by 1D, 2D NMR, and high-resolution mass spectra. Identified compounds 1–7 exhibited significant inhibition of α-amylase and moderate inhibition of α-glucosidase activities. Momordicoside G and gentisic acid 5-O-β-d-xyloside showed the highest inhibition of α-amylase (70.5%), and α-glucosidase (56.4%), respectively. Furthermore, molecular docking studies of isolated compounds 1–7 were able to bind to the active sites of both enzymes. Additionally, the isolated compounds 1–7 significantly attenuated lipopolysaccharide (LPS)-induced inflammation, downregulating the expression of pro-inflammatory markers NF-κB, INOS, IL-6, IL-1β, TNF-α, and Cox-2 in murine macrophage RAW 264.7 cells. One phenolic derivative, gentisic acid 5-O-β-d-xyloside, was isolated and identified for the first time from bitter melon, and significantly suppressed the expression of Cox-2 and IL-6 compared to the LPS-treated group. α-Amylase and α-glucosidase are targets of anti-diabetes drugs, our findings suggest that compounds purified from bitter melon may have potential to use as functional food ingredients for the prevention of type 2 diabetes and related inflammatory conditions.     

Chemical composition and antimicrobial,antioxidant, and anti-inflammatory activities of Lepidium sativum seed oil

Lepidium sativum (garden cress) seed oil was examined for its antimicrobial, antioxidant, and anti-inflammatory activities. The oil was obtained by hydrodistillation, where gas chromatography coupled with mass spectrometry that utilized to study its chemical composition. Microdilution method was used to test the antimicrobial effect of oil against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Salmonella enterica, Klebsiella pneumoniae, and Candida albicans. The antioxidant activity was assessed by radical scavenging activity assay using 2,2-diphenyl-1-picrylhydrazyl radical. The major constituents found in the oil were 7,10-hexadecadienoic acid, 11-octadecenoic acid, 7,10,13-hexadecatrienoic acid, and behenic acid. The minimum inhibitory concentration (MIC) against all pathogens was 47.5 mg/ml, except for Salmonella enterica, which showed MIC of 90 mg/ml. The oil demonstrated antioxidant activity in a dose dependent pattern, with a half maximal inhibitory concentration (IC₅₀) value of 40 mg/ml, and exerted anti-inflammatory activity, wherein 21% protection was shown at a concentration of 300 μg/ml. Thus, L. sativum seed oil shows antimicrobial, antioxidant, and anti-inflammatory properties.     

Properties of melanin from Lachnum YM156 and its hepatoprotective effect in Cd-exposure mice

Natural melanin was extracted from Lachnum YM156 (LIM). LIM had better thermostability and light resistance, and its solubility was relatively high under alkaline conditions. Simultaneously, we examined its hepatoprotective effect in Cd-exposure mice. Cd-exposure resulted in decreasing weight growth rate, raised liver index, elevated serum levels of alanine aminotransferase (ALT) and aspartate aminotransaminase (AST), and increased Cd accumulation in livers. Hepatic oxidative stress was evidenced by increased malondialdehyde (MDA) contents, decreased glutathione (GSH) contents, and decreased activities of dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) after CdCl₂ administration. Additionally, Cd-exposure also increased the liver level of tumor necrosis factor (TNF)-α and interleukin(IL)-1β. Furthermore, the result of quantitative real-time polymerase chain reaction(qRT-PCR) showed that Cd-exposure reduced the mRNA expression level of NF-E2-related factor 2 (Nrf2), heme oxygenase (HO-1), NADPH quinone oxidoreductase 1 (NQO-1), and elevated the mRNA expression level of factor-kappaB (NF-κB) p65, inducible nitric oxide synthase (iNOS) in livers. However, all these changes were dose-dependently reversed by LIM. Overall, the present findings demonstrated that LIM have the hepatoprotective effect through antioxidant and anti-inflammatory responses in Cd-exposure mice.
