Abstract
Sepsis is caused by a disordered host immune in response to infection and endothelial cells perform a crucial role in boosting immunity reaction in the pathophysiology of sepsis and septic organ failure. The aim of this study is to construct a novel erythrocyte membrane-derived nanosystems to reverse endothelial damage in sepsis. Herein, an innovative nanometer calcium metal-organic framework (Ca-MOF) is generated for the first time by using chelidonic acid as a ligand and calcium chloride as an ion donor for anti-inflammation. Then, zoliflodacin is loaded into Ca-MOF (CMZ) to sterilize and nanoscale erythrocyte membrane vesicles are prepared by modification with a γ3 peptide on the surface (γ3-RM) for precise targeting. Finally, γ3-RM camouflages the nanocore CMZ, to form novel erythrocyte membrane-camouflaged nanoparticle γ3-RCMZ. The superior performance of novel nanosystem results from its suitable biocompatibility, nontoxicity, specific targeting, and anti-inflammatory and bactericidal effects. Its anti-inflammatory mechanism mainly involves inhibiting the Caspase1-nuclear factor kappa-B (Caspase1-NF-κB) pathway and oxidative stress reduction to alleviate endothelial damage. Moreover, the findings have revealed for the first time that the bactericidal drug zoliflodacin also has anti-inflammatory effects in vivo and in vitro. Therefore, the novel nanosystem (γ3-RCMZ) provides a new nanotherapy strategy for sepsis treatment.

Khairnar SI, Kulkarni YA, Singh K. Mitigation of cisplatin-induced nephrotoxicity by chelidonic acid in Wistar rats. J Trace Elem Med Biol 2024; 81:127321. [PMID: 37918276 DOI: 10.1016/j.jtemb.2023.127321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 10/03/2023] [Accepted: 10/13/2023] [Indexed: 11/04/2023]
Abstract
INTRODUCTION Cisplatin, an anti-cancer drug is used to treat a wide range of solid tumors. Nevertheless, nephrotoxicity is the major adverse effect that restricts its clinical application. The present study focuses on the effect of chelidonic acid in cisplatin-induced nephrotoxicity. METHODS Wistar rats were injected with cisplatin (5 mg/kg, intraperitoneally (i.p.), once in a week for 4 weeks) and chelidonic acid (10, 20, and 40 mg/kg, per oral (p.o.) for 4 weeks). Body weight, urine, biochemical, and oxidative stress parameters were performed to evaluate the effect of chelidonic acid in cisplatin-induced nephrotoxicity in rats. Pro-inflammatory cytokines and nuclear factor erythroid 2-related factor 2 (Nrf2) concentrations were determined. Expression of phospho-AMP activated protein kinase (phospho-AMP) and hypoxia-inducible factor 1-alpha (HIF-1α) was studied with western blot. Haematoxylin and eosin, periodic acid-Schiff, and Masson's trichrome staining were used to study kidney tissues. RESULTS Relative kidney weight and urine output were significantly increased in cisplatin-administered rats. Whereas, albumin, and creatinine concentration were decreased, and treatment with chelidonic acid reverses these deleterious effects of cisplatin significantly. Kidney functions were improved by chelidonic acid treatment with a reduction in tumor necrosis factor-alpha (TNF-α), Interleukin-6 (IL-6), and transforming growth factor-beta (TGF-β1) concentration. The oxidative stress was decreased as compared to the cisplatin group. Furthermore, Nrf2 was significantly increased by chelidonic acid treatment. Chelidonic acid treatment significantly increased the expression of phospho-AMPK and HIF-1α in kidney tissue. Histopathological studies revealed that chelidonic acid reduced kidney damage. CONCLUSION The findings showed that chelidonic acid increases phospho-AMPK and HIF-1α in the kidney tissue and significantly lowers the inflammatory cytokines, thus it is an effective molecule for providing protection against cisplatin-induced nephrotoxicity.

Structure and Neuroprotector Properties of a Complex Compound of Lithium with Comenic Acid. Int J Mol Sci 2023; 25:286.

Abstract
The structure, antioxidant and neuroprotective properties of lithium comenate (lithium 5-hydroxy-4-oxo-4H-pyran-2-carboxylate) were studied. Lithium comenate was obtained by reacting comenic acid (H2Com) with lithium hydroxide in an aqueous solution. The structure of lithium comenate was confirmed via thermal analysis, mass spectrometry, IR, NMR and UV spectroscopy. The crystal structure was studied in detail via X-ray diffraction. The compound crystallized in a non-centrosymmetric space group of symmetry of the orthorhombic system Pna21 in the form of a hydrate, with three water molecules entering the first coordination sphere of the cation Li+ and one molecule forming a second environment through non-valent contacts. The gross formula of the complex compound was established [Li(HCom)(H2O)3]·H2O. It has been established that lithium comenate has a pronounced neuroprotective activity under the excitotoxic effect of glutamate, increasing the survival rate of cultured rat cerebellar neurons more than two-fold. It has also been found that the pre-stress use of lithium comenate at doses of 1 and 2 mg/kg has an antioxidant effect, which is manifested in a decrease in oxidative damage to the brain tissues of mice subjected to immobilization stress. Based on the data available in the literature, we believe that the high neuroprotective and antioxidant efficacy of lithium comenate is a consequence of the mutual potentiation of the pharmacological effects of lithium and comenic acid.

Abstract
Chelidonic acid is a phytoconstituent found in rhizomes of the perennial plant celandine. The current study aims to evaluate the acute and repeated dose oral toxicity study of chelidonic acid as per the OECD guidelines 425 and 407. The pharmacokinetic and toxicity profile of chelidonic acid was predicted using online servers and tools. A single dose of chelidonic acid (2000 mg/kg) was administered to female Wistar rats in an acute toxicity study, and the animals were monitored for 14 days. We studied the toxicity profile of chelidonic acid at 10, 20, and 40 mg/kg doses in Wistar rats for repeated dose toxicity (28 days). Clinical biochemistry, haematological, and urine parameters were estimated. A gross necropsy and histopathology were performed. A single oral dose of chelidonic acid (2000 mg/kg) showed no signs of toxicity or mortality. The Administration of chelidonic acid showed no significant alterations in haematological, biochemical, and urine parameters. The histopathology showed normal structure and architecture in all the vital organs. A gross necropsy of vital organs showed no signs of toxicity. The chelidonic acid was found to be safe at all selected dose levels in the acute and repeated dose toxicity study in rats.

Molecules 2023; 28:5807. [PMID: 37570777 PMCID: PMC10420846 DOI: 10.3390/molecules28155807] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/24/2023] [Accepted: 07/29/2023] [Indexed: 08/13/2023] Open
Abstract
Secondary varieties of date fruits are often discarded because they do not have commercial value. However, their phytochemicals are very similar to those of the primary ones and therefore, they can be valorized as a source of compounds of interest, mainly phenols and dietary fiber. Their chemical composition changes with ripening, so their characterization throughout this process is of great significance. Date fruit samples were harvested at Khalal, Rutab, and Tamer stages, and a mixture of fruits from ornamental date trees was also analyzed. Aqueous and ethanolic extracts were studied for their phenolic composition. In aqueous extracts, phenols decreased with ripening, while in the ethanolic ones having higher phenolic content. Chelidonic acid, a γ-pyrone, was the major compound found in all extracts, but in the ethanolic ones, flavonoids were also present in similar amounts. After purification by adsorption chromatography, all extracts were assayed for their antimicrobial activity. Those from the Tamer stage showed the highest activity, especially against Gram-positive bacteria. The fibrous residues after aqueous and ethanolic extractions were also characterized. Their chemical composition suggested that they can be considered as a good source of prebiotic arabinoxylans and antioxidant fiber, whose antiradical activity correlated with their phenolic content. Date fruits from secondary varieties are promising as a worthwhile starting point for obtaining new value-added products.

Asparagus Fructans as Emerging Prebiotics. Foods 2022; 12:foods12010081.

Abstract
Commercial fructans (inulin and oligofructose) are generally obtained from crops such as chicory, Jerusalem artichoke or agave. However, there are agricultural by-products, namely asparagus roots, which could be considered potential sources of fructans. In this work, the fructans extracted from asparagus roots and three commercial ones from chicory and agave were studied in order to compare their composition, physicochemical characteristics, and potential health effects. Asparagus fructans had similar chemical composition to the others, especially in moisture, simple sugars and total fructan contents. However, its contents of ash, protein and phenolic compounds were higher. FTIR analysis confirmed these differences in composition. Orafti®GR showed the highest degree of polymerization (DP) of up to 40, with asparagus fructans (up to 25) falling between Orafti®GR and the others (DP 10-11). Although asparagus fructan powder had a lower fructan content and lower DP than Orafti®GR, its viscosity was higher, probably due to the presence of proteins. The existence of phenolic compounds lent antioxidant activity to asparagus fructans. The prebiotic activity in vitro of the four samples was similar and, in preliminary assays, asparagus fructan extract presented health effects related to infertility and diabetes diseases. All these characteristics confer a great potential for asparagus fructans to be included in the prebiotics market.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) with a low cure rate. Periplaneta americana is a traditional American Cockroach and reportedly has potential therapeutic roles for UC treatment; however, its mechanisms remain unclear. To address this, we investigated the therapeutic effects and underlying molecular mechanisms of Ento-A, a Periplaneta americana extract, in a dextran sulfate sodium (DSS)-induced chronic and recurrent UC mouse model. Ento-A treatment decreased pro-inflammatory cytokine secretion, disease activity index (DAI), colon mucosa damage index (CMDI), histopathological scores (HS), and increased colon length. Additionally, Ento-A effectively increased interleukin-4 (IL-4), and forkhead transcription factor protein 3 (Foxp3) expression levels, while it abated interferon-γ (IFN-γ) and IL-17 levels in spleen lymphocytes. Conversely, in mesenteric lymph nodes, IL-4 and Foxp3 expression were decreased, while IFN-γ and IL-17 expression was increased. Furthermore, Ento-A blocked p-PI3K, p-AKT,*and p-NF-κB activation. In conclusion, Ento-A improved UC symptoms and exerted therapeutic effects by regulating immune responses and inhibiting PI3K/AKT/NF-κB signaling.

Abstract
Ulcerative colitis (UC) is a refractory inflammatory bowel disease that causes inflammation and ulcers in the digestive tract, and significantly reduces the patient's quality of life. While existing UC treatments have many challenges, nanotechnology, and small interfering RNA (siRNA) based formulations are novel and promising for UC treatment. We previously reported that intravenous administration of MPEG-PCL-CH2R4H2C nanomicelles had high inflammatory site accumulation and remarkable therapeutic effects on rheumatoid arthritis by a phenomenon similar to enhanced permeability and retention effect. In this study, we investigated the effects of siRNA delivered using MPEG-PCL-CH2R4H2C nanomicelles through intravenous administration to the inflammation site of dextran sulfate sodium-induced colitis mice. The MPEG-PCL-CH2R4H2C micelles had optimum physical properties and high siRNA compaction ability. Moreover, model-siRNA delivered through MPEG-PCL-CH2R4H2C showed higher accumulation in the inflammatory site than that of the naked siRNA. Furthermore, intravenous administration of MPEG-PCL-CH2R4H2C/siRelA micelles, targeting siRelA, a subunit of NF-κB, significantly decreased the shortening of large intestine, clinical score, and production of inflammatory cytokines compared the 5-ASA and naked siRelA. These results suggest that MPEG-PCL-CH2R4H2C is a useful carrier for the systemic delivery and accumulation of siRNA, thus improving its therapeutic effect.

We studied the antioxidant and cytoprotective effects of meconic acid in the model systems. Meconic acid, similar to commercial drug Mexidol, reduced the intensity of chemiluminescence in the model system of yolk lipoproteins. Meconic acid also reduced the toxic effect of glutamate on neurons in the primary cerebellar culture, but had no effect on cell viability under normal conditions.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease, and Gegen Qinlian Decoction (GQD), a Chinese botanical formula, has exhibited beneficial efficacy against UC. However, the mechanisms underlying the effect of GQD still remain to be elucidated. In this study, network pharmacology approach and molecular docking in silico were applied to uncover the potential multicomponent synergetic effect and molecular mechanisms. The targets of ingredients in GQD were obtained from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Bioinformatics Analysis Tool for Molecular mechANism of TCM (BATMAN-TCM) database, while the UC targets were retrieved from Genecards, therapeutic target database (TTD) and Online Mendelian Inheritance in Man (OMIM) database. The topological parameters of Protein-Protein Interaction (PPI) data were used to screen the hub targets in the network. The possible mechanisms were investigated with gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Molecular docking was used to verify the binding affinity between the active compounds and hub targets. Network pharmacology analysis successfully identified 77 candidate compounds and 56 potential targets. The targets were further mapped to 20 related pathways to construct a compound-target-pathway network and an integrated network of GQD treating UC. Among these pathways, PI3K-AKT, HIF-1, VEGF, Ras, and TNF signaling pathways may exert important effects in the treatment of UC via inflammation suppression and anti-carcinogenesis. In the animal experiment, treatment with GQD and sulfasalazine (SASP) both ameliorated inflammation in UC. The proinflammatory cytokines (TNF-α, IL-1β, and IL-6) induced by UC were significantly decreased by GQD and SASP. Moreover, the protein expression of EGFR, PI3K, and phosphorylation of AKT were reduced after GQD and SASP treatment, and there was no significance between the GQD group and SASP group. Our study systematically dissected the molecular mechanisms of GQD on the treatment of UC using network pharmacology, as well as uncovered the therapeutic effects of GQD against UC through ameliorating inflammation via downregulating EGFR/PI3K/AKT signaling pathway and the pro-inflammatory cytokines such as TNF-α, IL-1β and IL-6.

Abstract
The biomolecule chelidonic acid (H2chel, 4-oxo-4H-pyran-2,6-dicarboxylic acid) has been used to build new coordination polymers with the bridging N,N′-ligands 4,4′-bipyridine (4,4-bipy) and 1,2-bis(4-pyridyl)ethane (bpe). Four compounds have been obtained as single crystals: 1D cationic coordination polymers [M(4,4-bipy)(OH2)4]2+ with chelidonate anions and water molecules in the second coordination sphere in 1∞[Zn(4,4-bipy)(H2O)4]chel·3H2O (2) and in the two pseudopolymorphic 1∞[Cu(4,4-bipy)(H2O)4]chel·nH2O (n = 3, 4a; n = 6, 4b), and the 2D neutral coordination polymers 2∞[Zn(chel)(4,4-bipy)(H2O)]·2H2O (1) and 2∞[Zn(chel)(bpe)(H2O)]·H2O (3) where the chelidonate anion acts as a bridging ligand. The effects of the hydrogen bonds on the crystal packing were analyzed. The role of the water molecules hosted within the crystals lattices was also studied.

Abstract
Chelidonium majus L. is a medicinal plant well-known as a valuable source of isoquinoline alkaloids, which has a variety of pharmacological properties including anti-viral and anti-bacterial effects. However, considerable intraspecific bio-morphological variability in C. majus complicates raw material identification and verification. For the first time, we have brought into cultivation five populations of C. majus subsp. majus originated from different regions, and performed their agro-morphological, microanatomical and molecular cytogenetic characterization. All examined populations produced high seed (18.6–19.9 kg/ha) and raw material (0.84–1.08 t/ha) yields; total alkaloid contents were within 0.30–0.38%. Nevertheless, significant differences in plant morphology and yield-contributing traits were observed. The performed microanatomical analysis of leaves and flowers in double- and normal-flowered plants revealed micro-diagnostic features (including tissue topography, types of stomata, laticifers, structure of leaf mesophyll, hairs, sepals and petals) important for identification of C. majus raw materials. The analysis of chromosome morphology, DAPI-banding patterns, FISH mapping of 45S and 5S rDNA and also chromosome behavior in meiosis allowed us to identify for the first time all chromosomes in karyotypes and confirm relative genotype stability of the studied plants. Our findings indicate that the examined C. majus populations can be used in further breeding programs.

Abstract
Biologicals like anti-tumor necrosis factor (TNF) therapy for Crohn's disease (CD) are safe and effective but there is a significant rate of primary and secondary nonresponse in the patients. In this study, we applied a computational approach to discover novel drug therapies for anti-TNF refractory CD in silico. We use a transcriptome dataset (GSE100833) for the anti-TNF refractory CD patients from NCBI GEO. After co-expression analysis, we specifically investigated the extent of protein-protein interactions among genes in clusters based on a protein-protein interaction database, STRING. Pathway analysis was performed using the clEnrich function based on KEGG gene sets. Co-expressed genes in cluster 1, 2, 3, 4, up or down-regulated genes and all differentially expressed genes are highly connected. Among them, cluster 1, which is highly enriched for chemokine signaling, also showed enrichment for cytokine-cytokine receptor interaction and identifies several drugs including cyclosporin with known efficacy in CD. Vorinostat, histone deacetylase inhibitors, and piperlongumine, which is known to have inhibitory effect on activity of NF-κB, were also identified. Some alkaloids were also selected as potential therapeutic drugs. These finding suggest that they might serve as a novel therapeutic option for anti-TNF refractory CD and support the use of public molecular data and computational approaches to discover novel therapeutic options for CD.

Abstract
Inflammation plays a crucial role in the development of many complex diseases and disorders including autoimmune diseases, metabolic syndrome, neurodegenerative diseases, and cardiovascular pathologies. Prostaglandins play a regulatory role in inflammation. Cyclooxygenases are the main mediators of inflammation by catalyzing the initial step of arachidonic acid metabolism and prostaglandin synthesis. The differential expression of the constitutive isoform COX-1 and the inducible isoform COX-2, and the finding that COX-1 is the major form expressed in the gastrointestinal tract, lead to the search for COX-2-selective inhibitors as anti-inflammatory agents that might diminish the gastrointestinal side effects of traditional non-steroidal anti-inflammatory drugs (NSAIDs). COX-2 isoform is expressed predominantly in inflammatory cells and decidedly upregulated in chronic and acute inflammations, becoming a critical target for many pharmacological inhibitors. COX-2 selective inhibitors happen to show equivalent efficacy with that of conventional NSAIDs, but they have reduced gastrointestinal side effects. This review would elucidate the most recent findings on selective COX-2 inhibition and their relevance to human pathology, concretely in inflammatory pathologies characterized by a prolonged pro-inflammatory status, including autoimmune diseases, metabolic syndrome, obesity, atherosclerosis, neurodegenerative diseases, chronic obstructive pulmonary disease, arthritis, chronic inflammatory bowel disease and cardiovascular pathologies.

Abstract
4-oxo-4H-pyran-2.6-dicarboxylic acid (chelidonic acid, ChA) in the native state and in the complex with calcium [Ca(ChA)(H2O)3], named saucalchelin (CaChA), was isolated from the extract of Saussurea controversa leaves for the first time for the Asteraceae family. The structure of ChA was determined by NMR, MS and confirmed by X-ray analysis of its monomethyl ester, and CaChA was described by IR, ICP-MS, CHN analysis. The yield of ChA and CaChA was 45 mg/g and 70 mg/g of extract, respectively. The osteogenic activity of ChA, n-monobutyl ester of chelidonic acid, and CaChA has been studied in vitro in a 21-day culture of human adipose-derived multipotent mesenchymal stromal cells (hAMMSCs) in a standard nutrient medium without osteogenic supplements. CaChA significantly stimulated the growth of cell mass and differentiation of hAMMSCs into osteoblasts with subsequent mineralization of the culture and it may be a promising substance for accelerating bone tissue regeneration and engineering.

Abstract
The composite vibrational structure near 3650–3200 and 3000–2400 cm−1 in the observed IR absorption spectrum of Chelidonic acid has been explained in terms of intra- and inter-molecular −O−H∙∙∙O H-bonding attributed to monomer and dimer species computed at B3LYP/6–311++G(d,p) level. Three of the six dimer species derived out of ten monomeric components have shown both intra- and inter-molecular H-bonding. Vibrational modes of the monomer and dimer species are satisfactorily identified with the observed IR and Raman bands including frequency shifts associated with the H-bondings. The H-bond interactions in the monomer and dimer species have been characterized in terms of electron density, ρ(r), its Laplacian, ∇2ρ(r) and potential energy density at the O∙∙∙H bond critical points (BCPs) based on the Atoms in Molecules (AIM) theory. The attractive (van der Waals, H-bonds) and repulsive steric clash (SC) interactions are explained using computed reduced density gradient values from the noncovalent interaction (NCI) method. The AIM analysis confirms the presence of the intra- and inter-molecular H-bondings in the monomer/dimer species. The natural bond orbital (NBO) analysis of the natural charges and stabilization energy of the H-bonds for the dimer species further points to the stronger inter-than intra-molecular H-bonding.

Abstract
Chelidonium majus is a traditional medicinal plant, which commonly known as a rich resource for the major benzylisoquinoline alkaloids (BIAs), including morphine, sanguinarine, and berberine. To understand the biosynthesis of C. majus BIAs, we performed de novo transcriptome sequencing of its leaf and root tissues using Illumina technology. Following comprehensive evaluation of de novo transcriptome assemblies produced with five programs including Trinity, Bridger, BinPacker, IDBA-tran, and Velvet/Oases using a series of k-mer sizes (from 25 to 91), BinPacker was found to produce the best assembly using a k-mer of 25. This study reports the results of differential gene expression (DGE), functional annotation, gene ontology (GO) analysis, classification of transcription factor (TF)s, and SSR and miRNA discovery. Our DGE analysis identified 6,028 transcripts that were up-regulated in the leaf, and 4,722 transcripts that were up-regulated in the root. Further investigations showed that most of the genes involved in the BIA biosynthetic pathway are significantly expressed in the root compared to the leaf. GO analysis showed that the predominant GO domain is "cellular component", while TF analysis found bHLH to be the most highly represented TF family. Our study further identified 10 SSRs, out of a total of 39,841, that showed linkage to five unigenes encoding enzymes in the BIA pathway, and 10 conserved miRNAs that were previously not detected in this plant. The comprehensive transcriptome information presented herein provides a foundation for further explorations on study of the molecular mechanisms of BIA synthesis in C. majus.

Abstract
As antique as Dioscorides era are the first records on using Chelidonium as a remedy to several sicknesses. Inspired by the "signatura rerum" principle and an apparent ancient folk tradition, various indications were given, such as anti-jaundice and cholagogue, pain-relieving, and quite often mentioned-ophthalmological problems. Central and Eastern European folk medicine has always been using this herb extensively. In this region, the plant is known under many unique vernacular names, especially in Slavonic languages, associated or not with old Greek relation to "chelidon"-the swallow. Typically for Papaveroidae subfamily, yellow-colored latex is produced in abundance and leaks intensely upon injury. Major pharmacologically relevant components, most of which were first isolated over a century ago, are isoquinoline alkaloids-berberine, chelerythrine, chelidonine, coptisine, sanguinarine. Modern pharmacology took interest in this herb but it has not ended up in gaining an officially approved and evidence-based herbal medicine status. On the contrary, the number of relevant studies and publications tended to drop. Recently, some controversial reports and sometimes insufficiently proven studies appeared, suggesting anticancer properties. Anticancer potential was in line with anecdotical knowledge spread in East European countries, however, in the absence of directly-acting cytostatic compounds, some other mechanisms might be involved. Other properties that could boost the interest in this herb are antimicrobial and antiviral activities. Being a common synanthropic weed or ruderal plant, C. majus spreads in all temperate Eurasia and acclimates well to North America. Little is known about the natural variation of bioactive metabolites, including several aforementioned isoquinoline alkaloids. In this review, we put together older and recent literature data on phytochemistry, pharmacology, and clinical studies on C. majus aiming at a critical evaluation of state-of-the-art from the viewpoint of historical and folk indications. The controversies around this herb, the safety and drug quality issues and a prospective role in phytotherapy are discussed as well.

Abstract
OBJECTIVE To investigate the anti-inflammatory effects of decursin and decursinol angelate-rich Angelica gigas Nakai (AGNE) on dextran sulfate sodium (DSS)-induced murine ulcerative colitis (UC). METHODS The therapeutic effect of an AGNE was analyzed in a mouse model of UC induced by DSS. Disease activity index values were measured by clinical signs such as a weight loss, stool consistency, rectal bleeding and colon length. A histological analysis was performed using hematoxylin and eosin staining. Key inflammatory cytokines and mediators including IL-6, TNF-α, PGE2, COX-2 and HIF-1α were assayed by enzyme-linked immunosorbent assay or western blotting. RESULTS Treatment with the AGNE at 10, 20, and 40 mg/kg alleviated weight loss, decreased disease activity index scores, and reduced colon shortening in mice with DSS-induced UC. AGNE inhibited the production of IL-6 and TNF-α in serum and colon tissue. Moreover, AGNE suppressed the increased expression of COX-2 and HIF-1α and the increased production of PGE2 in colon tissue were observed in mice with DSS-induced UC. Additionally, histological damage was also alleviated by AGNE treatment. CONCLUSIONS The findings of this study verified that AGNE significantly improves clinical symptoms and reduces the activity of various inflammatory mediators. These results indicate the AGNE has the therapeutic potential in mice with DSS-induced UC.

Abstract
This study focuses on the comparative in vitro cytotoxicity of chelidonine and homochelidonine on human cancer and non-cancer cells. Both alkaloids produced a decrease in cellular growth in a dose-dependent manner exhibiting greater potency in cancer cells. The growth inhibitory effect was evidenced in both ovarian carcinoma A2780 and lung fibroblast MRC-5 cells by inducing G2 and mitotic phase cell cycle arrest. Results indicated that the extent of apoptosis induced by chelidonine and homochelidonine was correlated to sensitivity to the antiproliferative activity of the evaluated compounds. Western blotting suggested that the cellular toxicological mechanism of chelidonine is related to the differential upregulation of phospho-Chk2, p21Cip1/Waf1, phospho-ERK1/2 and phospho-p38 in various cell types, leading to alternations in the suppression of proliferation and either induction or prevention of apoptosis. Chelidonine showed the more potent effects and also affected the cell cycle checkpoints and MAPK signaling pathways within cells.

Abstract
The present study evaluated the immunomodulatory effects of chelidonic acid, a secondary plant metabolite, with therapeutic potential in allergic disorders, in experimental animals. In mast cell degranulation studies, ovalbumin immunized and challenged rats, chelidonic acid (1, 3 and 10mg/kg, i.p.) dose relatedly prevented ovalbumin challenge induced mast cell degranulation by differing degrees when compared with vehicle treated group, and these effects were comparable with prednisolone (10mg/kg). A reduction in post-challenge mortality was also observed in all treated groups. Further, there were reductions in the blood eosinophil counts and serum IgE levels after chelidonic acid treatment. Chelidonic acid also inhibited histamine release from rat peritoneal mast cells (RPMC) in vitro, in a dose related manner. In tests for adaptive immunity, in rats immunized with sheep RBC, chelidonic acid differentially suppressed the (a) plaque forming cell (PFC) count in rat splenic cells, (b) anti-SRBC antibody titre and serum IgG levels and (c) increases in foot pad thickness in the DTH assay - all of which were comparable with prednisolone. These experimental results are discussed in light of the possible therapeutic potential of chelidonic acid in allergic disorders.

Abstract
Depression is usually accompanied by neuro-inflammatory reactions. Chelidonic acid, in particular, has shown anti-inflammatory effects. The objective of this study was to evaluate the anti-depressant effects of chelidonic acid and to discuss the potential mechanisms of a forced swimming test. Chelidonic acid was administered orally once a day for 14 days. On the 14th day, chelidonic acid resulted in a significant decrease in immobility time during the forced swimming test without alteration of locomotor activity, in an open field test. Chelidonic acid also increased the number of nissl bodies in the hippocampus. Brain-derived neurotrophic factor expression and extracellular signal-regulated protein kinase phosphorylation in the hippocampus were up-regulated by the administration of chelidonic acid. Chelidonic acid administration significantly increased the mRNA expression of hippocampal estrogen receptor-β. The levels of hippocampal interleukin (IL)-1β, IL-6, and tumor necrosis factor-α were effectively attenuated by the administration of chelidonic acid. In addition, chelidonic acid significantly increased the levels of 5-hydroxytryptamine (serotonin), dopamine, and norepinephrine compared with those levels for the mice that were administered distilled water in the hippocampus. These results suggest that chelidonic acid might serve as a new therapeutic strategy for the regulation of depression associated with inflammation.

Abstract
Kouyanqing Granule (KYQG) is a traditional Chinese herbal formula composed of Flos lonicerae (FL), Radix scrophulariae (RS), Radix ophiopogonis (RO), Radix asparagi (RA), and Radix et rhizoma glycyrrhizae (RG). In contrast with the typical method of separating and then biologicalily testing the components individually, this study was designed to establish an approach in order to define the core bioactive ingredients of the anti-inflammatory effects of KYQG based on the relevance analysis between chemical characters and biological effects. Eleven KYQG samples with different ingredients were prepared by changing the ratios of the 5 herbs. Thirty-eight ingredients in KYQG were identified using Ultra-fast liquid chromatography-Diode array detector-Quadrupole-Time-of-flight-Tandem mass spectrometry (UFLC-DAD-Q-TOF-MS/MS) technology. Human oral keratinocytes (HOK) were cultured for 24 hours with 5% of Cigarette smoke extract (CSE) to induce inflammation stress. Interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumour necrosis factor-α (TNF-α) were evaluated after treatment with the eleven KYQG samples. Grey relational analysis(GRA), Pearson’s correlations (PCC), and partial least-squares (PLS) were utilized to evaluate the contribution of each ingredient. The results indicated that KYQG significantly reduced interleukin-1β, interleukin-6, interleukin-8, and tumour necrosis factor-α levels, in which lysine, γ-aminobutyric acid, chelidonic acid, tyrosine, harpagide, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isoquercitrin, luteolin-7-o-glucoside, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid, angoroside C, harpagoside, cinnamic acid, and ruscogenin play a vital role.

Abstract
AIM: To investigate the protective effect of compound dracorhodin enema on the lung and intestine of mice with distal ulcerative colitis (UC).
METHODS: Sixty male BALB/c mice were randomly divided into four groups (n = 15 each): a normal group, a dextran sulfate sodium (DSS) group, a compound dracorhodin enema group, and a DSS + compound dracorhodin enema group. After inducing UC, the normal group and DSS group were given 1 mL saline, and the other two groups were given compound dracorhodin enema [0.075 g/(kg•d), 1 mL] by gavage. After treatment, disease activity index (DAI) score, colonic histopathology score (HI), lung HI score, and hematoxylin-eosin (HE) staining were used to evaluate the severity of inflammation. Enzyme-linked immunosorbent assay (ELISA), immunohistochemistry, and real-time quantitative PCR (RT-QPCR) assay were used to detect the expression of interleukin (IL)-6 in the lung and colon.
RESULTS: Compared with the normal group and compound dracorhodin enema group, DAI score, colonic HI score, and lung HI score were significantly higher in the other two groups (P < 0.05). Compared with the DSS + compound dracorhodin enema group, colonic and pulmonary tissue inflammation was significantly more severe and pulmonary and colonic expression of IL-6 was significantly higher in the DSS group (P < 0.05).
CONCLUSION: Compound dracorhodin enema can decrease the expression of IL-6 and therefore alleviate UC and UC related lung injury in mice.

Abstract
Ulcerative colitis (UC) is an inflammatory destructive disease of the large intestine occurred usually in the rectum and lower part of the colon as well as the entire colon. Drug therapy is not the only choice for UC treatment and medical management should be as a comprehensive whole. Many synthetic drugs are available for the treatment of UC like 5-aminosalicylic acid, oral or systemic corticosteroids, immunomodulator, etc. but these drugs are associated with many serious side effects after long term use or have certain disadvantage or not suitable for the use in some patients. In short synthetic drugs have many disadvantages and for this reason effective and safe alternative drug treatment for the UC is the challenge. Herbal drugs are found to be very promising results of the treatment of UC and enzymatic level. Researchers explored many herbal drugs for the treatment and even many more may found effective in the treatment of UC. At this point we feel herbal medicine is the better alternative for the treatment of UC.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease. Semen Crotonis Pulveratum (SCP) has been used as a traditional medicine for the treatment of UC. However, its molecular mechanisms of action have not yet been elucidated. In the present study, we aimed to investigate the preliminary mechanisms of the role of SCP on trinitrobenzene sulphonic acid (TNBS)-induced UC in rats and hydrogen peroxide (H2O2)-induced intestinal cell apoptosis in vitro. Wistar rats (n=9 per group) were randomly divided into 4 groups: the normal control group, the UC group, the UC + SCP group and the UC + sulfasalazine group as a positive control. The proportion of CD4+CD25+ T cells and CD4+CD25+Foxp3+ Tregs, and the expression levels of interleukin (IL)-6 and IL-10 in the peripheral blood, as well as the expression levels of cyclooxygenase-2 (COX-2) and intercellular adhesion molecule-1 (ICAM-1) in the colon tissues were determined by flow cytometry, ELISA and immunohistochemical staining, respectively. Rat intestinal epithelial (IEC-6) cell apoptosis induced by H2O2 was determined by TUNEL assay, flow cytometry using Annexin V/propidium iodide (PI) staining and western blot analysis of caspase-3 activation, respectively. Significantly higher proportions of circulating CD4+CD25+ T cells and CD4+CD25+Foxp3+ Tregs were present in the UC + SCP group compared with the UC group. A significantly decreased expression of IL-6 and an increased expression of IL-10 were also observed in the UC + SCP group compared with UC group. SCP significantly reduced the UC-induced increase in the expression of COX-2 and ICAM-1 in the colon tissues. SCP inhibited cell apoptosis and caspase-3 activation induced by H2O2 in the ICE-6 cells. Our data thus indicate that SCP inhibits inflammation in UC by increasing the proportion of circulating Tregs, altering cytokine production and decreasing COX-2 and ICAM-1 expression. In addition it protects against H2O2-induced intestinal cell apoptosis in vitro.
