Pharmaceuticals (Basel) 2023; 16:1597. [PMID: 38004462 PMCID: PMC10675456 DOI: 10.3390/ph16111597] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 11/03/2023] [Accepted: 11/07/2023] [Indexed: 11/26/2023] Open
Abstract
A library of 24 congeners of the natural product sulfuretin were evaluated against nine panels representing nine cancer diseases. While sulfuretin elicited very weak activities at 10 µM concentration, congener 1t was identified as a potential compound triggering growth inhibition of diverse cell lines. Mechanistic studies in HCT116 colon cancer cells revealed that congener 1t dose-dependently increased levels of cleaved-caspases 8 and 9 and cleaved-PARP, while it concentration-dependently decreased levels of CDK4, CDK6, Cdc25A, and Cyclin D and E resulting in induction of cell cycle arrest and apoptosis in colon cancer HCT116 cells. Mechanistic study also presented MET receptor tyrosine kinase as the molecular target mediating the anticancer activity of compound 1t in HCT116 cells. In silico study predicted folded p-loop conformation as the form of MET receptor tyrosine kinase responsible for binding of compound 1t. Together, the current study presents compound 1t as an interesting anticancer lead for further development.

BMB Rep 2023; 56:496-501. [PMID: 37748761 PMCID: PMC10547967] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 04/28/2023] [Accepted: 05/22/2023] [Indexed: 09/27/2023] Open
Abstract
Elongation of most bones occur at the growth plate through endochondral ossification in postnatal mammals. The maturation of chondrocyte is a crucial factor in longitudinal bone growth, which is regulated by a complex network of paracrine and endocrine signaling pathways. Here, we show that a phytochemical sulfuretin can stimulate hypertrophic chondrocyte differentiation in vitro and in vivo. We found that sulfuretin stabilized nuclear factor (erythroid-derived 2)-like 2 (Nrf2), stimulated its transcriptional activity, and induced expression of its target genes. Sulfuretin treatment resulted in an increase in body length of zebrafish larvae and induced the expression of chondrocyte markers. Consistently, a clinically available Nrf2 activator, dimethyl fumarate (DMF), induced the expression of hypertrophic chondrocyte markers and increased the body length of zebrafish. Importantly, we found that chondrocyte gene expression in cell culture and skeletal growth in zebrafish stimulated by sulfuretin were significantly abrogated by Nrf2 depletion, suggesting that such stimulatory effects of sulfuretin were dependent on Nrf2, at least in part. Taken together, these data show that sulfuretin has a potential use as supporting ingredients for enhancing bone growth. [BMB Reports 2023; 56(9): 496-501].

Abstract
Sulfuretin, a naturally occurring aurone is reported to inhibit macrophage and microglia activation. A series of aurones incorporating basic amines and lipophilic functionalities at ring A and/or ring B were synthesized to improve upon present sulfuretin activity towards targeting brain microglia while overcoming the blood-brain barrier (BBB). Evaluation of the ability of the aurones to inhibit lipopolysaccharide (LPS)-stimulated nitric oxide (NO) secretion by murine BV-2 microglia has identified several inhibitors showing significant NO reduction at 1 to 10 µM. Potent inhibitors were represented by aurones with bulky, planar moieties at ring A (3f) or at ring B (1e and 1f) and having a pendant piperidine at ring B (1a, 2a, 2b, and 3f). The active aurones inhibited the BV-2 microglia polarizing towards the M1 state as indicated by attenuation of IL-1β and TNF-α secretions in LPS-activated microglia but did not induce the microglia towards the M2 state. The aurones 2a, 2b, and 1f showed high passive BBB permeability in the parallel artificial membrane permeability assay (PAMPA) owing to their optimal lipophilicities. 2a, being non-cell toxic, BBB permeant and potent, represents a new lead for the development of aurones as inhibitors of activated microglia.

Naringin and Naringenin Polyphenols in Neurological Diseases: Understandings from a Therapeutic Viewpoint. LIFE (BASEL, SWITZERLAND) 2022; 13:life13010099. [PMID: 36676048 PMCID: PMC9867091 DOI: 10.3390/life13010099] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 12/21/2022] [Accepted: 12/22/2022] [Indexed: 01/01/2023]
Abstract
The glycosides of two flavonoids, naringin and naringenin, are found in various citrus fruits, bergamots, tomatoes, and other fruits. These phytochemicals are associated with multiple biological functions, including neuroprotective, antioxidant, anticancer, antiviral, antibacterial, anti-inflammatory, antiadipogenic, and cardioprotective effects. The higher glutathione/oxidized glutathione ratio in 3-NP-induced rats is attributed to the ability of naringin to reduce hydroxyl radical, hydroperoxide, and nitrite. However, although progress has been made in treating these diseases, there are still global concerns about how to obtain a solution. Thus, natural compounds can provide a promising strategy for treating many neurological conditions. Possible therapeutics for neurodegenerative disorders include naringin and naringenin polyphenols. New experimental evidence shows that these polyphenols exert a wide range of pharmacological activity; particular attention was paid to neurodegenerative diseases such as Alzheimer's and Parkinson's diseases, as well as other neurological conditions such as anxiety, depression, schizophrenia, and chronic hyperglycemic peripheral neuropathy. Several preliminary investigations have shown promising evidence of neuroprotection. The main objective of this review was to reflect on developments in understanding the molecular mechanisms underlying the development of naringin and naringenin as potential neuroprotective medications. Furthermore, the configuration relationships between naringin and naringenin are discussed, as well as their plant sources and extraction methods.

Abstract
Background. Magnoliae flos is the dried flower bud of Magnolia biondii and related plants. It has been used as a medicinal herb for the treatment of rhinitis, sinusitis, and sinus headaches. Nevertheless, the effects of Magnoliae flos in microbial infection or sepsis remain unclear. In this study, we investigated the anti-inflammatory effects of Magnoliae flos water extract (MF) in lipopolysaccharide- (LPS-) induced septic mice and LPS-stimulated RAW264.7 macrophages. Results. We found that MF reduced the mortality of LPS-challenged mice. Enzyme immunoassays and reverse transcription polymerase chain reaction analysis revealed that MF administration attenuated mRNA expression and protein production of proinflammatory mediators, including cyclooxygenase 2, inducible nitric oxide synthase, tumor necrosis factor-α, and interleukin-6. In parallel to these results in mice, pretreatment with MF suppressed the LPS-induced production of proinflammatory mediators in RAW264.7 macrophages. In addition, we found that MF exerted its suppressive effects by inhibiting the activation of the mitogen-activated protein kinase, nuclear factor-κB, and signal transducer and activator of transcription pathways at the protein level. Conclusion. MF could be a potential therapeutic agent for regulating excessive inflammatory responses in sepsis.

Abstract
BACKGROUND Herb-derived therapeutics is an attractive strategy to treat depression. Here we report the ameliorating effects of Sulfuretin, an anti-inflammatory compound in a depressive mouse model. METHODS Immobility times were obtained in the tail suspension test and forced swim test performed from day 14 to day 16. Quantitative real-time PCR (qRT-PCR) and Western blot were used to measure brain-derived neurotrophic factor (BDNF) and the extracellular signal-regulated kinase (ERK) pathway of the hippocampus tissue on day 17. SL327 was used to block the ERK pathway in mice to evaluate the interaction between Sulfuretin and the ERK pathway. Mice were treated with Sulfuretin for 14 days before lipopolysaccharide (LPS) injection (0.83 mg/kg/day, i.p.) for two days. RESULTS Behavior tests showed that Sulfuretin dose-dependently decreased immobility times correlated with depression symptoms. BDNF levels and ERK signaling were significantly restored in the Sulfuretin-treated mice, showing the improvement of brain function. Blocking the p-ERK signaling abrogated the effects of Sulfuretin in improving behaviors and levels of BDNF. CONCLUSION Our study suggests that Sulfuretin exhibits anti-depressive function in LPS-induced depressive mice, in which the ERK signaling plays an essential role.

Genes Dis 2021; 8:867-881. [PMID: 34522714 PMCID: PMC8427253 DOI: 10.1016/j.gendis.2020.11.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 11/14/2020] [Accepted: 11/16/2020] [Indexed: 01/03/2023] Open
Abstract
Sulfuretin is a flavonoid that protects cell from damage induced by reactive oxygen species and inflammation. In this study, we investigated the role of sulfuretin in the processing of amyloid precursor protein (APP), in association with the two catalytic enzymes the α-secretase a disintegrin and metalloproteinase (ADAM10), and the beta-site APP cleaving enzyme 1 (BACE1) that play important roles in the generation of β amyloid protein (Aβ) in Alzheimer's disease (AD). We found that sulfuretin increased the levels of the immature but not the mature form of ADAM10 protein. The enhanced ADAM10 transcription by sulfuretin was mediated by the nucleotides −444 to −300 in the promoter region, and was attenuated by silencing or mutation of transcription factor retinoid X receptor (RXR) and by GW6471, a specific inhibitor of peroxisome proliferator-activated receptor α (PPAR-α). We further found that sulfuretin preferentially increased protein levels of the immature form of APP (im-APP) but significantly reduced those of BACE1, sAPPβ and β-CTF, whereas Aβ1-42 levels were slightly increased. Finally, the effect of sulfuretin on BACE1 and im-APP was selectively attenuated by the translation inhibitor cycloheximide and by lysosomal inhibitor chloroquine, respectively. Taken together, (1) RXR/PPAR-α signaling was involved in sulfuretin-mediated ADAM10 transcription. (2) Alteration of Aβ protein level by sulfuretin was not consistent with that of ADAM10 and BACE1 protein levels, but was consistent with the elevated level of im-APP protein, suggesting that im-APP, an isoform mainly localized to trans-Golgi network, plays an important role in Aβ generation.

Anti-inflammatory effects of three withanolides isolated from Physalis angulata L. in LPS-activated RAW 264.7 cells through blocking NF-κB signaling pathway. JOURNAL OF ETHNOPHARMACOLOGY 2021; 276:114186. [PMID: 33957208 DOI: 10.1016/j.jep.2021.114186] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Revised: 04/26/2021] [Accepted: 04/29/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Physalis angulata L. is commonly used in many countries as popular medicine for the treatment of a variety of diseases such as malaria, hepatitis, dermatitis and rheumatism. But the anti-inflammatory active constituents of this medicinal plant and their molecular mechanism are still not elucidated clearly. AIM OF THE STUDY The aim of the study is to isolate and identify a series of compounds from the ethanolic extract of Physalis angulata L., and to investigate the anti-inflammatory activities in vitro and the molecular mechanism of physagulin A, physagulin C, and physagulin H. MATERIALS AND METHODS In order to further understand the anti-inflammatory mechanism of the three compounds, their potential anti-inflammatory activities were investigated in vitro in LPS-activated RAW 264.7 macrophage cells by Griess assay, ELISA, Western blot and immunofluorescence methods in the present study. RESULTS Physagulin A, physagulin C, and physagulin H could not only inhibit the release of NO, PGE2, IL-6 and TNF-α, but also could down-regulate the expression of iNOS and COX-2 proteins. Furthermore, physagulin A, physagulin C, and physagulin H could remarkably block the degradation of IκB-α and the nuclear translocation of NF-κB/p65 in LPS-activated RAW 264.7 cells. However, none of them could inhibit the phosphorylation of MAPKs family proteins ERK, JNK and p38. Thus, the anti-inflammatory actions of physagulin A, physagulin C, and physagulin H were mainly due to the significant inhibition of NF-κB signaling pathway rather than MAPKs signaling pathway. CONCLUSIONS All the results clearly showed that physagulin A, physagulin C, and physagulin H demonstrated potent anti-inflammatory activity and can be used as novel NF-κB inhibitors. They are potential to be developed as an alternative or complementary agents for inflammatory diseases.

Abstract
Transformation of 15-ene steviol (ent-13-hydroxy-kaur-15-en-19-oic acid) by growth cultures of Aspergillus niger BCRC 32720, Cunninghamella bainieri ATCC 9244, and Mortierella isabellina ATCC 38063 was conducted to generate various derivatives for the development of bioactive compounds. Four previously undescribed compounds along with six known compounds were obtained. The newly identified isolates were characterized using 1D and 2D NMR, IR, and HRESIMS, and three compounds were further confirmed by X-ray crystallographic analyses. Subsequently, the effects of 15-ene steviol and its derivatives on lipopolysaccharide (LPS)-induced cytokine production by THP-1 cells were examined, with dexamethasone used as a positive control. Results indicated that most of the tested compounds showed lower inhibitory effects than those detected in the dexamethasone-treated group, except that 15-ene steviol showed better effects than dexamethasone on the reduction of LPS-induced monocyte chemoattractant protein (MCP)-1, -2, and -3 release. Three specialized products similarly showed better effects than dexamethasone on the inhibition of LPS-induced secretion of regulated on activation, normal T cell expressed and secreted (RANTES). Moreover, none of the tested compounds showed any cytotoxicity or triggered cell apoptosis, and none affected the protein integrity of toll-like receptor 4 (TLR4) or MyD88, suggesting that these compounds may exert the anti-inflammatory activity downstream of membrane-associated TLR4 and MyD88 molecules.

Ambati GG, Jachak SM. Natural Product Inhibitors of Cyclooxygenase (COX) Enzyme: A Review on Current Status and Future Perspectives. Curr Med Chem 2021; 28:1877-1905. [PMID: 32484764 DOI: 10.2174/0929867327666200602131100] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Revised: 04/28/2020] [Accepted: 05/06/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Several clinically used COX-1 and COX-2 inhibitor drugs were reported to possess severe side effects like GI ulcers and cardiovascular disturbances, respectively. Natural products being structurally diverse always attracted the attention of chemists/ medicinal chemists as a potential source of lead molecules in the drug discovery process. COX-2 inhibitory natural products also possess potential cancer chemopreventive property against various cancers including that of colon, breast and prostate. METHODS Various in vitro, in vivo and in silico standardized methods were used to evaluate COX inhibition property of different secondary metabolites isolated from plant, microbial and marine origin. RESULTS We had earlier reported a detailed account of natural product inhibitors of COX reported during 1995-2005, in 2006. In the proposed review, we report 158 natural product inhibitors of COX during 2006 to 2019 belonging to various secondary metabolite classes such as alkaloids, terpenoids, polyphenols as flavonoids, chromones, coumarins, lignans, anthraquinones, naphthalenes, curcuminoids, diarylheptanoids and miscellaneous compounds of plant and marine origin. Further Structure Activity Relationship (SAR) studies of possible leads are also included in the article. CONCLUSION COX inhibitors served as a potential source of lead molecules for the discovery and development of anti-inflammatory drugs. Compilation of natural product and semisynthetic inhibitors of COX may serve as valuable information to the researchers who are looking for possible lead molecules from a natural source to conduct further preclinical and clinical studies.

Lipopolysaccharide-Induced Nitric Oxide and Prostaglandin E2 Production Is Inhibited by Tellimagrandin II in Mouse and Human Macrophages. Life (Basel) 2021; 11:life11050411. [PMID: 33946374 PMCID: PMC8146495 DOI: 10.3390/life11050411] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 04/09/2021] [Accepted: 04/14/2021] [Indexed: 12/21/2022] Open
Abstract
Sepsis develops from a serious microbial infection that causes the immune system to go into overdrive. The major microorganisms that induce sepsis are Gram-negative bacteria with lipopolysaccharide (LPS) in their cell walls. Nitric oxide (NO) and cyclooxygenase-2 (COX-2) are the key factors involved in the LPS-induced pro-inflammatory process. This study aimed to evaluate the effects of polyphenol Tellimagrandin II (TGII) on anti-inflammatory activity and its underlying basic mechanism in murine macrophage cell line RAW 264.7 and human monocyte-derived macrophages. Macrophages with more than 90% cell viability were found in the cytotoxicity assay under 50 μM TGII. Pre- or post-treatment with TGII significantly reduced LPS-induced inducible nitric oxide synthase (NOS2) protein and mRNA expression, reducing LPS-induced COX-2 protein. Downstream of NOS2 and COX-2, NO and prostaglandin E2 (PGE2) were significantly inhibited by TGII. Upstream of NOS2 and COX-2, phospho-p65, c-fos and phospho-c-jun were also reduced after pre-treatment with TGII. Mitogen-activated protein kinases (MAPKs) are also critical to nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) stimulation, and phospho-p38 expression was found to have been blocked by TGII. TGII efficiently reduces LPS-induced NO production and its upstream regulatory factors, suggesting that TGII may be a potential therapeutic agent for sepsis and other inflammatory diseases.

Integrating Ethnobotany, Phytochemistry, and Pharmacology of Cotinus coggygria and Toxicodendron vernicifluum: What Predictions can be Made for the European Smoketree? Front Pharmacol 2021; 12:662852. [PMID: 33953688 PMCID: PMC8092975 DOI: 10.3389/fphar.2021.662852] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Accepted: 03/22/2021] [Indexed: 11/13/2022] Open
Abstract
The smoketree (Cotinus coggygria) is a historically known medicinal plant from Southeast Europe. Its ethnomedicinal use in skin and mucosal lesions is commonly accepted across countries. Other utilizations reported locally include fever reduction, cardiac diseases, hypertension, urinary diseases, cough, asthma, hemorrhoids, diabetes, numbness of arm, liver disease, and cancer. Departing from the smoketree's traditional uses, this review summarizes investigations on the phytochemistry and bioactivity of the plant. In vitro and in vivo experiments supporting wound-healing, anti-inflammatory, antibacterial, cytotoxic, antioxidative, hepatoprotective, and antidiabetic effects are presented. Metabolites from smoketree that are responsible for the main pharmacological effects of smoketree are pointed out. Furthermore, the review performs a comparison between C. coggygria and the lacquer tree (Toxicodendron vernicifluum). The latter is a comprehensively studied species used in Asian phytotherapy, with whom the European smoketree shares a consistent pool of secondary metabolites. The comparative approach aims to open new perspectives in the research of smoketree and anticipates an optimized use of C. coggygria in therapy. It also points out the relevance of a chemosystematic approach in the field of medicinal plants research.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 267:113490. [PMID: 33091501 DOI: 10.1016/j.jep.2020.113490] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 10/13/2020] [Accepted: 10/16/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Physalis Calyx seu Fructus is typically used to treat inflammatory diseases such as upper respiratory tract infection and acute tonsillitis in clinical practice of China. Physalin A, a main active ingredient of this traditional Chinese medicine (TCM), has been reported for its significant anti-tumor activity. However, most reports focused on the studies of its anti-tumor activity, the anti-inflammatory activity of physalin A and its molecular mechanism are still not elucidated clearly. AIM OF THE STUDY The aim of the study was to investigate the anti-inflammatory activities both in vitro and in vivo and molecular mechanism of physalin A. MATERIALS AND METHODS The potential anti-inflammatory properties of physalin A were evaluated in vitro by lipopolysaccharide (LPS)-induced RAW 264.7 macrophage cells, and in vivo via two typical acute inflammation murine models. Some important inflammation-related molecules were analyzed by enzyme-linked immuno sorbent assay (ELISA) and Western blotting. RESULTS The results showed that physalin A inhibited carrageenan-induced paw edema of rats and capillary permeability of mice induced by acetic acid in vivo. Furthermore, physalin A also significantly reduced the release of inflammatory mediators nitric oxide (NO), prostaglandin E2 (PGE2), and tumor necrosis factor-α (TNF-α) induced by lipopolysaccharide (LPS) in RAW 264.7 in vitro. Further investigations indicated that physalin A can down-regulate the high expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in a dose-dependent manner. Physalin A remarkably blocked the degradation of inhibitor of nuclear factor kappa B alpha (IκB-α) and the nuclear translocation of nuclear factor-κB (NF-κB) p65 induced by LPS in RAW 264.7 cells. However, physalin A did not significantly inhibit the phosphorylation of mitogen-activated protein kinases (MAPKs) family proteins c-Jun N-terminal kinase (JNK) or extracellular signal-regulated kinase (ERK) or p38. CONCLUSIONS All the results clearly illustrated that the anti-inflammatory action of physalin A is due to the inactivation of NF-κB signal pathway, but is irrelevant to the MAPKs pathway.

Abstract
A simple and efficient matrix solid-phase dispersion via high-performance liquid chromatography coupled with a photodiode array detector was developed to analyze the following flavonoids of Rhus verniciflua Stokes: fisetin, fustin, butein, sulfuretin, garbanzol, and quercetin. The optimum conditions for the procedure was the use of Zeolite Socony Mobil-twenty-two molecular sieves as the adsorbent, sample:adsorbent ratio of 2:5, grinding for 3 min, and use of 8 mL of 70% methanol:water as the elution solvent. The method was validated for linearity, precision, reproducibility, limit of detection, and limit of quantification. The method exhibited excellent linearity for all six flavonoids. The intra- and interday precisions over a range of concentrations were below 3.0% and limits of quantification for the six flavonoids were 0.16 and 0.50 μg/mL. Compared with other published methods, the proposed method was more effective, rapid, and required less reagents. Therefore, the combination of matrix solid-phase dispersion and high-performance liquid chromatography coupled with photodiode array detector showed excellent reproducibility and simplicity and could be suitable for the extraction and quantification of multiple flavonoids in R. verniciflua Stokes samples.

Abstract
Abstract
Various mixtures were prepared depending on the mixing ratio of Scutellaria baicalensis hot water extract (SB-HW), and Chrysanthemum morifolium ethanol extract (CM-E) and their anti-inflammatory activity were compared. Among them, SB-HW (80 μg/mL)/CM-E (120 μg/mL) or SB-HW (40 μg/mL)/CM-E (160 μg/mL) significantly inhibited LPS-stimulated NO and IL-6 levels in RAW 264.7 cells. The SB-HW (80 μg/mL)/CM-E (120 μg/mL) mixture, which was determined as active mixture, significantly reduced MUC5AC secretion in PMA and LPS-induced NCI-H292 cells. The active mixture also reduced the production of PGE2 and IL-8 in PMA-induced A549 cells. LC-MS/MS analysis showed that the active mixture was composed of high contents of flavone glycosides, such as baicalin and cynaroside. Western blot analysis indicated that the active mixture suppressed phosphorylation of ERK, JNK, and p38, associating with the inhibition of MAPK signaling. Taken together, our results suggest that the active mixture could be applied as a new anti-inflammatory herbal medicine.

Abstract
As an important metabolite in cholesterol metabolism, dehydroepiandrosterone (DHEA) can modulate the immune function in animals and humans, but the underlying mechanism is still unclear. The present study investigated the effect and mechanism of DHEA's anti-inflammatory action in primary mice peritoneal macrophages infected with E. coli O157:H7. The finding showed that DHEA improved the phagocytic ability in E. coli O157:H7-infected macrophages. DHEA inhibited the cytokines (including tumor necrosis factor-α, interleukin-1β and interleukin-6) secretion in E. coli O157:H7-infected macrophages. The inducible nitric oxide synthase and cyclooxygenase-2 protein level were significantly decreased in E. coli O157:H7-infected macrophages treated with DHEA. In addition, DHEA markedly decreased the phospho (p)-p38 MAPK protein level in E. coli O157:H7-infected macrophages. Furthermore, DHEA prevented the nuclear translocation of NF-κB by decreasing of p-IκB-α protein level in E. coli O157:H7-infected macrophage; and these effects of DHEA were heightened when the cells were pre-treated with p38 MAPK inhibitor SB203580. Our data indicated that DHEA alleviates the pro-inflammatory mediator production in E. coli O157:H7-infected mice peritoneal macrophages; and this beneficial action associated with it prevents the activation of p38 MAPK and NF-κB signaling pathway.

Abstract
Skin photoaging is mainly caused by exposure to ultraviolet (UV) light, which increases expressions of matrix metalloproteinases (MMPs) and destroys collagen fibers, consequently inducing wrinkle formation. Nutritional factors have received scientific attention for use as agents for normal skin functions. The aim of this study was to investigate the effect of hot water extracts from the leaves of Hydrangea serrata (Thunb.) Ser. (WHS) against ultraviolet B (UVB)-induced skin photoaging and to elucidate the underlying molecular mechanisms in human foreskin fibroblasts (Hs68) and HR-1 hairless mice. WHS recovered UVB-reduced cell viability and ameliorated oxidative stress by inhibiting intracellular reactive oxygen species (ROS) generation in Hs68 cells. WHS rescued UVB-induced collagen degradation by suppressing MMP expression, and reduced the mRNA levels of inflammatory cytokines. These anti-photoaging activities of WHS were associated with inhibition of the activator protein 1 (AP-1), signal transduction and activation of transcription 1 (STAT1), and mitogen-activated protein kinase (MAPK) signaling pathways. Oral administration of WHS effectively alleviated dorsal skin from wrinkle formation, epidermal thickening, collagen degradation, and skin dehydration in HR-1 hairless mice exposed to UVB. Notably, WHS suppressed UVB activation of the AP-1 and MAPK signaling pathways in dorsal mouse skin tissues. Taken together, our data indicate that WHS prevents UVB-induced skin damage due to collagen degradation and MMP activation via inactivation of MAPK/AP-1 signaling pathway.

Abstract
Atopic dermatitis (AD) is characterized by relapsing pruritus and skin dryness. Due to the pathogenic multiplicity and the adverse effects associated with the current therapeutics, development of transdermal drug delivery system is becoming an area of interest. Here, a novel topical film prepared with Rhus verniciflua extract (RVE)-loaded pullulan hydrogel (RVE@PH) was synthesized and tested its therapeutic efficacy on the AD rats modeled by neonatal capsaicin injection method. The RVE@PH was characterized by a Fourier-transform infrared spectroscopy and an in vitro release assay. Rat pups were randomly divided into two groups: vehicle-treated (VEH; n = 5) and capsaicin-treated (n = 15). The latter were given capsaicin subcutaneously at 24 h after birth for AD induction and further divided into three groups (n = 5 per each): not treated (CAP), pullulan hydrogel-applied (PH), and RVE@PH-applied (RVE-PH). The pullulan hydrogel and RVE@PH were topically applied on shoulder lesions for 14 days (from 42 to 56 days after birth). Their phenotypes were compared based on the dermatitis score, epidermal thickness, mast cell infiltration, and serum myeloperoxidase (MPO) activities. The PH group showed significant attenuation in all the aforementioned values compared to the CAP group, suggesting that pullulan hydrogel itself has therapeutic activity against AD. Notably, the attenuations were more potent in the RVE-PH group than the PH group, indicating that the therapeutic efficacy against AD is augmented by the presence of RVE, a loaded pharmaceutic. Collectively, these results indicate that RVE@PH inhibits AD through exerting the dual roles, that is, the pullulan hydrogel-mediated physical and RVE-mediated pharmaceutical actions. © 2019 Wiley Periodicals, Inc.

Abstract
Cirsium japonicum var. ussuriense (Regel) Kitam. ex Ohwi (C. ussuriense) is known as "Dae-Gye" or "Korean milk thistle". C. ussuriense have long been used as a folk medicinal plant for inflammatory diseases such as hepatitis, nephritis, and mastitis in Korea, China, and Japan. To reveal the anti-inflammatory components of C. ussuriense, we isolated three flavone glycosides (linarin, cirsimarin, and hispidulin-7-O-neohesperidoside) from the aerial part of C. ussuriense and evaluated their inhibitory effects on LPS-induced pro-inflammatory mediators in macrophages. We also investigated the involving molecular mechanisms of cirsimarin. Among three flavone glycosides, cirsimarin showed vastly superior inhibitory potency in LPS-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production. Cirsimarin concentration-dependently inhibited LPS-induced inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) at the protein and mRNA levels in macrophages. Cirsimarin suppressed the production and mRNA expression of tumor necrosis factor- α (TNF-α) and interleukin (IL)-6 in LPS-stimulated RAW 264.7 and bone marrow-derived macrophages. Moreover, molecular data presented that cirsimarin down-regulated the phosphorylation of Janus kinase (JAK)/signal transducer and activator of transcriptions (STATs) and p38 mitogen-activated protein kinase (MAPK), and nuclear translocation of interferon regulatory factor (IRF)-3. Collectively, cirsimarin may be an active ingredient responsible for anti-inflammatory effects of C. ussuriense and it may act as a promising therapeutic against inflammatory diseases by suppressing the JAK/STAT and IRF-3 signaling pathway.

Abstract
Parkinson's disease (PD) is the second most common neurodegenerative disease. It is caused by the death of dopaminergic neurons in the substantia nigra pars compacta. Oxidative stress and mitochondrial dysfunction contribute to the loss of dopaminergic neurons in PD. Sulfuretin is a potent antioxidant that is reported to be beneficial in the treatment of neurodegenerative diseases. In this study, we examined the protective effect of sulfuretin against 1-methyl-4-phenyl pyridinium (MPP⁺)-induced cell model of PD in SH-SY5Y cells and the underlying molecular mechanisms. Sulfuretin significantly decreased MPP⁺-induced apoptotic cell death, accompanied by a reduction in caspase 3 activity and polyADP-ribose polymerase (PARP) cleavage. Furthermore, it attenuated MPP⁺-induced production of intracellular reactive oxygen species (ROS) and disruption of mitochondrial membrane potential (MMP). Consistently, sulfuretin decreased p53 expression and the Bax/Bcl-2 ratio. Moreover, sulfuretin significantly increased the phosphorylation of Akt, GSK3β, and ERK. Pharmacological inhibitors of PI3K/Akt and ERK abolished the cytoprotective effects of sulfuretin against MPP⁺. An inhibitor of GSK3β mimicked sulfuretin-induced protection against MPP⁺. Taken together, these results suggest that sulfuretin significantly attenuates MPP⁺-induced neurotoxicity through Akt/GSK3β and ERK signaling pathways in SH-SY5Y cells. Our findings suggest that sulfuretin might be one of the potential candidates for the treatment of PD.

Abstract
Post-menopausal osteoporosis (PMO) is a major global human health concern. Owing to the need for therapeutic drugs without side effects, natural extracts containing various polyphenolic compounds that may exert estrogenic effects have been studied in depth. Rhus verniciflua Stokes (RVS), which has been used as a traditional herbal medicine for centuries in Korea, was recently revealed to exert estrogenic effects attributable to its bioactive ingredients sulfuretin and butein, which have strong estrogen receptor–binding affinities. In this study, the protective potential of RVS in PMO was evaluated by using an experimental animal model of PMO, which was established by ovariectomy (OVX) of female Sprague Dawley rats. The oral administration of RVS at 20 mg/kg or 100 mg/kg for 8 weeks markedly protected against OVX-induced atrophy of the uterine tube and reversed the elevation in the ratio of serum receptor activator of nuclear factor-κB ligand to osteoprotegerin, which is a marker of disease severity. In addition, RVS inhibited OVX-induced tibia bone loss, activated osteogenic activity, and suppressed osteoclastic activity in the tibial epiphyseal plate, a region of bone remodeling. Collectively, these factors indicated that the oral intake of RVS might be beneficial for the prevention of PMO.

Abstract
Rhus verniciflua Stoke has been commonly used in traditional medicine to treat gastrointestinal (GI) dysfunction diseases. In order to investigate pharmacological properties of Rhus verniciflua Stoke water extract (RVX) on cisplatin-induced amnesia, RVX (0, 25, 50, or 100 mg/kg) was orally administrated for five consecutive days after a single intraperitoneal injection of cisplatin (6 mg/kg) to SD rat. Cisplatin injection significantly increased the kaolin intake (emesis) but reduced the normal diet intake (anorexia) whereas the RVX treatment significantly improved these abnormal diet behaviors at both the acute and delayed phase. The serotonin concentration and the related gene expressions (5-HT3 receptors and SERT) in small intestine tissue were abnormally altered by cisplatin injection, which were significantly attenuated by the RVX treatment. Histological findings of gastrointestinal tracts, as well as the proteins level of proinflammatory cytokines (TNF-α, IL-6, and IL-1β), revealed the beneficial effect of RVX on cisplatin-induced gastrointestinal inflammation. In addition, RVX significantly improved cisplatin-induced myelosuppression, as evidenced by the observation of leukopenia and by histological examinations in bone marrow. Our findings collectively indicated Rhus verniciflua Stoke improved the resistance of rats to chemotherapy-related adverse effects in the gastrointestinal track and bone marrow.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nauclea officinalis Pierrc ex Pitard. is a Chinese medicinal herb that contains high level of alkaloids which is the most abundant and active constituent. Strictosamide isolated from Nauclea officinalis Pierrc ex Pitard. showed significant effects on inflammatory response, compared with pumiloside, 3-epi-pumiloside, vincosamide, 3α,5α-tetrahydrodeoxycordifoline lactam and naucleamide A-10-O-β-D-glucopyranoside of this plant. AIM OF STUDY we investigated the biological activities of the six compounds mentioned-above, and the underlying molecular mechanism exerted by the most potent one, strictosamide. MATERIALS AND METHODS The effects of strictosamide and other five compounds on the inhibitory activity of nitric oxide (NO) were screened by Griess test. The contents of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in media were detected by using Enzyme-linked immunosorbent (ELISA) kits. The effects on the mRNA expression of nitric oxide synthase (iNOS), TNF-α and IL-1β of strictosamide were further investigated by RT-qPCR. Western blot assay was conducted to illustrate the effects of strictosamide on iNOS and phosphorylation of p65, inhibitor of NF-κB (IκB)-α, IκB-kinase (IKK)-α as well as p-extracellular signal-regulated kinase (ERK), p-c-jun N-terminal kinase (JNK) and p-p38 in the protein levels. RESULTS Strictosamide potently suppressed the productions of NO, TNF-α and IL-1β in LPS-induced RAW 264.7 macrophages, and it dose-dependently alleviated the LPS-simulated protein level of iNOS as well as the mRNA expressions of iNOS, TNF-α and IL-1β. In addition, molecular data revealed that strictosamide markedly decreased the expressions of p-p65, p-IκBα and p-IKKα. Furthermore, strictosamide significantly attenuated LPS-induced the phosphorylation of p38, ERK and JNK. CONCLUSIONS At present study, the results indicated that the anti-inflammatory activity of strictosamide was associated with the restraint of NO, TNF-α and IL-1β via negative regulation of both NF-κB and mitogen-activated protein kinases (MAPKs) in LPS-induced RAW 264.7 cells.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Corydalis bungeana Turcz. (C. bungeana) is one of traditionally used medicines in China and possesses various biological effects, such as anti-inflammatory, antibacterial activity and inhibition of the immune function of the host. AIM OF THE STUDY we studied the anti-inflammatory effect and molecular mechanism involved of C. bungeana both in vitro and in vivo model system in which the inflammatory response was induced by LPS treatment. MATERIALS AND METHODS Anti-inflammatory activity of C. bungeana was investigated by LPS-induced RAW 264.7 macrophages and BALB/c mice. The production and expression of pro-inflammatory cytokines were evaluated by Griess reagent, ELISA kits and RT-qPCR, respectively. Phosphorylation status of IκBα and p65 was illustrated by western blot assay. RESULTS C. bungeana reduced the secretion of NO, TNF-α, IL-6 and IL-1β through inhibiting the protein expression of iNOS, TNF-α, IL-6 and IL-1β in vitro and in vivo. Western blot analysis suggested that C. bungeana supressed NF-κB activation via regulating the phosphorylation of IκBα and p65. Immunohistochemical assay also demostrated the histological inflammatory change in liver tissue. CONCLUSIONS The results indicate that C. bungeana supresses the activation of NF-κB signaling pathway through inhibiting phosphorylation of IκBα and p65, which results in good anti-inflammatory effect. In addition, C. bungeana attenuates inflammatory reaction by supressing the expression of various inflammatory cytokines both in vivo and in vitro.

The comparison of neuroprotective effects of isoliquiritigenin and its Phase I metabolites against glutamate-induced HT22 cell death. Bioorg Med Chem Lett 2016; 26:5639-5643.

Abstract
It is becoming increasingly important to investigate drug metabolites to evaluate their toxic or preventive effects after administration of the parent compound. In our previous study, isoliquiritigenin isolated from Glycyrrhizae Radix effectively protected mouse-derived hippocampal neuronal cells (HT22) against 5mM glutamate-induced oxidative stress. However, there is little information on the protective effects of the metabolites of isoliquiritigenin on HT22 cells. In this study, isoliquiritigenin and its Phase I metabolites were prepared and their neuroprotective activities on glutamate-treated HT22 cells were compared. The prepared metabolites were liquiritigenin (1), 2',4,4',5'-tetrahydroxychalcone (2), sulfuretin (3), butein (4), davidigenin (5), and cis-6,4'-dihydroxyaurone (6). Among the six metabolites, 4 showed better neuroprotective effects than the parent compound, isoliquiritigenin. Our study suggests that the neuroprotective effect of isoliquiritigenin could be elevated by its active metabolite 4, which is a chalcone containing a catechol group in the B ring.

Quercetin modulates toll-like receptor-mediated protein kinase signaling pathways in oxLDL-challenged human PBMCs and regulates TLR-activated atherosclerotic inflammation in hypercholesterolemic rats. Mol Cell Biochem 2016; 423:53-65. [PMID: 27665434 DOI: 10.1007/s11010-016-2824-9] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2016] [Accepted: 09/08/2016] [Indexed: 11/28/2022]
Abstract
Toll-like receptors (TLRs) are pattern recognition receptors that have a unique and essential function in innate immunity. The effect of quercetin on TLR-mediated downstream signaling mechanism and its effect on TLR-mediated MAP kinase and Akt pathways were studied in oxLDL-stimulated hPBMCs using specific inhibitors. The pretreatment of hPBMCs with specific TLR inhibitor, CLI-095, decreased the NF-κB nuclear translocation and TNF-α release by oxLDL. When the cells treated with inhibitor and quercetin together, the inhibition was more effective. The specific inhibitor for p38 MAPK, SB203580, reduced the phosphorylated p38 level and decreased the NF-κB activation and TNF-α release by oxLDL-challenged hPBMCs. This inhibitor showed enhanced inhibition when treated with quercetin together. The inhibitors for ERK1/2, PD98059, and for JNK, SP606125, also showed inhibitory effect on NF-κB activation and TNF-α release by oxLDL-simulated hPBMCs. Quercetin supplementation enhanced the inhibition of nuclear translocation of NF-κB and the release of cytokines. TLR4 inhibition study confirmed the downstream signaling mechanism mediated by NF-κB which is involved in the oxLDL-induced inflammatory response, and quercetin suppresses the cytokine, TNF-α release by modulating TLR-NF-κB signaling pathway. In addition to NF-κB signaling pathway, inflammation induced by oxLDL was also related to the activation of p38MAPK, ERK1/2 and JNK, and Akt pathways, and the protective effect of quercetin may be also related to the inhibition of activation of these pathways. Quercetin significantly downregulated the elevated mRNA expression of TLRs and cytokine TNF-α in HCD-fed atherosclerotic rats in vivo. As quercetin possesses inhibition on both TLR-NF-κB signaling pathway and TLR-mediated MAPK pathway, it is evident that it can be used as a therapeutic agent to ameliorate atherosclerotic inflammation. Since quercetin is the major flavonoid and forms the backbone of many other flavonoids and this study provides strong evidence that it has potent anti-inflammatory effect, quercetin may be a promising agent for the prevention and treatment of atherosclerosis and promote health by reducing harmful vascular inflammation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nauclea officinalis has been traditionally used in China for the treatment of fever, pneumonia and enteritidis etc. This study aims to investigate effects of N. officinalis on the inflammatory response as well as the possible molecular mechanism in LPS-stimulated RAW 264.7 murine macrophage cells. MATERIALS AND METHODS Anti-inflammatory activity of N. officinalis (10, 20, 50, and 100µg/mL) was investigated by using LPS-induced RAW 264.7 macrophages. The NO production was determined by assaying nitrite in culture supernatants with the Griess reagent. The levels of TNF-α, IL-6 and IL-1β in culture media were measured with ELISA kits. Real time fluorescence quantitative PCR was detected for mRNA expression of iNOS, TNF-α, IL-6 and IL-1β. Western blot assay was performed to illustrate the inhibitory effects of N. officinalis on phosphorylation of IκB-α and NF-κB p65. RESULTS Treatment with N. officinalis (10-100µg/mL) dose-dependently inhibited the production as well as mRNA expression of NO, TNF-α, IL-6 and IL-1β in RAW 264.7 macrophages. Western blot assay suggested that the mechanism of the anti-inflammatory effect was associated with the inhibition of phosphorylation of IκB-α and NF-κB p65. CONCLUSIONS The results indicated that N. officinalis potentially inhibited the activation of upstream mediator NF-κB signaling pathway via suppressing phosphorylation of IκB-α and NF-κB p65 to inhibit LPS-stimulated inflammation.

Abstract
Rhus verniciflua stokes (RVS) (Anacardiaceae) has been traditionally used as a folk remedy for gastritis, several cancers, and various metabolic diseases. The present study evaluated the anti-inflammatory effect of RVS extract standardized to fustin content using lipopolysaccharide (LPS)-stimulated rats. The rats were randomly divided into six groups and intragastrically administered 0, 100, 250, or 500 mg/kg body weight (bw) of RVS or 15 mg/kg bw of fustin for 14 days. LPS was intraperitoneally injected 18 h before sacrifice. The nitric oxide levels of RVS extract in either the serum or liver were significantly decreased compared to the LPS-treated rats (P<.05). The treatment with the RVS extract also blunted the rise of malondialdehyde levels in the liver (P<.05). The administration of RVS extract and fustin significantly prevented the elevation of interleukin 6 cytokine, iNOS, and COX-2 mRNA expression in the liver. Inflammatory cell infiltration was also significantly attenuated by the RVS extract or fustin supplementation. These results suggest that our standardized RVS extract has preventive effects on inflammatory reactions.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Toxicodendron vernicifluum (Stokes) F.A. Barkley (Anacardiaceae) has traditionally been used as a food supplement and in traditional herbal medicine to treat inflammatory diseases and cancers for centuries in Korea. This study was designed to isolate the bioactive constituents from the ethanol extract of Toxicodendron vernicifluum bark and evaluate their cytotoxic and anti-inflammatory activities. MATERIAL AND METHODS Bioassay-guided fractionation and chemical investigation of the ethanol extract of Toxicodendron vernicifluum bark resulted in the isolation and identification of three new polyphenols (1-3) and six flavonoids (4-9). The structures of the isolated compounds were elucidated by spectroscopic analysis, including 1D and 2D nuclear magnetic resonance (NMR) ((1)H, (13)C, COSY, HMQC and HMBC experiments), and high resolution (HR)-mass spectrometry, and their absolute configurations were further confirmed by chemical methods and circular dichroism (CD) data analysis. Compounds 1-9 were evaluated for their antiproliferative activities against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and HCT-15), and anti-inflammatory activities by measuring nitric oxide (NO) levels in the medium of murine microglia BV-2 cells. RESULTS The isolated compounds were characterized as in the following: three new polyphenols, rhusopolyphenols G-I (1-3) and six flavonoids including two aurones, 2-benzyl-2,3',4',6-tetrahydroxybenzo[b]furan-3(2H)-one (4), sulfuretin (5), two dihydroflavonols, (+)-(2S,3R)-fustin (6), (+)-epitaxifolin (7), one chalcone, butein (8), and one flavonol, fisetin (9). The published NMR assignments of 4 were corrected by the detailed analysis of spectroscopic data in this study. Among the tested compounds, compounds 4-9 showed antiproliferative activity against the tested cells, with IC50 values of 4.78-28.89 μM. Compounds 5 and 8 significantly inhibited NO production in lipopolysaccharide (LPS)-stimulated BV-2 cells with IC50 values of 23.37 and 11.68 μM, respectively. CONCLUSIONS Polyphenols including flavonoids were one of the main constituents of Toxicodendron vernicifluum bark, and activities demonstrated by the isolated compounds support the ethnopharmacological use of Toxicodendron vernicifluum as anti-cancer and/or anti-inflammatory agents.

Anti-inflammatory effect of a standardized triterpenoid-rich fraction isolated from Rubus coreanus on dextran sodium sulfate-induced acute colitis in mice and LPS-induced macrophages. JOURNAL OF ETHNOPHARMACOLOGY 2014; 158 Pt A:291-300. [PMID: 25446582 DOI: 10.1016/j.jep.2014.10.044] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2014] [Revised: 09/23/2014] [Accepted: 10/22/2014] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rubus coreanus Miquel (Rosaceae), the Korean black raspberry, has traditionally been used to treat inflammatory diseases including diarrhea, asthma, stomach ailment, and cancer. Although previous studies showed that the 19α-hydroxyursane-type triterpenoids isolated from Rubus coreanus exerted anti-inflammatory activities, their effects on ulcerative colitis and mode of action have not been explored. This study was designed to assess the anti-inflammatory effects and the molecular mechanisms involving19α-hydroxyursane-type triterpenoid-rich fraction from Rubus coreanus (TFRC) on a mice model of colitis and lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. MATERIALS AND METHODS Experimental colitis was induced by DSS for 7 days in ICR mice. Disease activity indices (DAI) took into account body weight, stool consistency, and gross bleeding. Histological changes and macrophage accumulation were observed by immunohistochemical analysis. Pro-inflammatory markers were determined using immunoassays, RT-PCR, and real time PCR. Signaling pathway involving nuclear factor-κB (NF-κB) and mitogen-activated protein kinases (MAPKs) activation was determined by luciferase assay and Western blotting. RESULTS In DSS-induced colitis mice, TFRC improved DAIs and pathological characteristics including colon shortening and colonic epithelium injury. TFRC suppressed tissue levels of pro-inflammatory cytokines and reduced macrophage infiltration into colonic tissues. In LPS-induced RAW 264.7 macrophages, TFRC inhibited the production of NO, PGE2, and pro-inflammatory cytokines by down-regulating the activation of NF-κB and p38 MAPK signaling. CONCLUSION The study demonstrates that TFRC has potent anti-inflammatory effects on DSS-induced colonic injury and LPS-induced macrophage activation, and supports its possible therapeutic and preventive roles in colitis.

Abstract
A series of chalcones and aurones were synthesized and evaluated in vitro as monoamine oxidase inhibitors (MAOi). Our results show that aurones, which had not been previously reported as MAOi, are MAO-B inhibitors. Thus, both families inhibited selectively the B isoform of MAO in the micromolar range, offering novel scaffolds for the design of new and potent MAO inhibitors. The main structural requirements for their activity were characterized with the aid of 3D-QSAR and docking studies.

Shin JS, Choi HE, Kim SD, Lee YS, Cho YW, Lee KT. Anti-inflammatory effects of 7-hydroxyl-1-methylindole-3-acetonitrile, a synthetic arvelexin derivative, on the macrophages through destabilizing mPGES-1 mRNA and suppressing NF-κB activation. Chem Biol Interact 2014; 224:68-77. [PMID: 25451575 DOI: 10.1016/j.cbi.2014.10.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2014] [Revised: 09/04/2014] [Accepted: 10/06/2014] [Indexed: 01/24/2023]
Abstract
We previously demonstrated that 7-hydroxyl-1-methylindole-3-acetonitrile (7-HMIA), a synthesized analog of arvelexin, showed the strong inhibitory effects on LPS-induced NO and PGE2 production in macrophages. In this study, we focused on elucidating the anti-inflammatory properties of 7-HMIA and the mechanisms involved using in vitro and in vivo experimental models. In LPS-induced RAW 264.7 macrophages, 7-HMIA significantly inhibited the release of proinflammatory mediators such as prostaglandin E2 (PGE2), nitric oxide (NO), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6). We also found that 7-HMIA suppressed PGE2 production not by inhibiting cyclooxygenase-2 (COX-2) expression or activity, but rather by suppressing the mRNA stability of microsomal prostaglandin E synthase (mPGES-1). Furthermore, 7-HMIA mediated attenuation of inducible NO synthase (iNOS), TNF-α, and IL-6 was closely associated with suppression of transcriptional activities of nuclear factor-kappa B (NF-κB), by decreasing p65 nuclear translocation and Akt phosphorylation. Animal studies revealed that 7-HMIA potently suppressed the carrageenan-induced paw edema and myeloperoxidase (MPO) activity in paw tissues. Taken together, our data indicated that the molecular basis for the anti-inflammatory properties of 7-HMIA involved the inhibition of mRNA stability of mPGES-1 and PI3K/Akt-mediated NF-κB pathways.
