[PMID: 37144394 DOI: 10.1080/14786419.2023.2208257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Accepted: 04/20/2023] [Indexed: 05/06/2023]
Abstract
Previous studies on Ranunculus sceleratus L. have shown the existence of coumarins and their anti-inflammatory effect. Phytochemical work was conducted to investigate the bioactive compounds, leading to the isolation of two undescribed benzopyran derivatives, namely ranunsceleroside A (1) and B (3), together with two known coumarins (2, 4) from the whole plant of R. sceleratus L. All compounds were structurally identified by extensive spectroscopic analysis and then investigated for their inhibitory effect on nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) production induced by lipopolysaccharide (LPS) in RAW 264.7 murine macrophages, repectively. As a result, compound 1-4 presented inhibitory effects on the production of NO, TNF-α, IL-1β, and IL-6 in a concentration-dependent manner, which provides a potential chemical basis for the traditional use of R. sceleratus L. as an anti-inflammatory plant.

Abstract
Whey protein hydrolysate from Binglangjiang buffalo, a unique genetic resource, has anti-inflammatory activity, but its anti-inflammatory composition and effects are unknown. The aim of this study was to investigate the anti-inflammatory peptides from Binglangjiang buffalo whey protein hydrolysate. A total of 1483 peptides were identified using LC-MS/MS, and 12 peptides were chosen for chemical synthesis using peptidomics, and then two novel anti-inflammatory peptides (DQPFFHYN (DN8) and YSPFSSFPR (YR9)) were screened out using LPS-stimulated RAW264.7 cells. The molecular weights of DN8 and YR9 with β-turn conformations were 1067.458 Da and 1087.52 Da, respectively, and showed a high in-vitro safety profile and thermal stability, but were intolerant to pepsin. Furthermore, ELISA and Western blot analysis indicated that peptides DN8 and YR9 significantly suppressed the secretion of pro-inflammatory cytokines NO, TNF-α, and IL-6 and the expression of mediators iNOS, TNF-α, and IL-6 in LPS-stimulated RAW264.7 cells. The study provides insights into the development of novel food-based anti-inflammatory nutritional supplements.

Abstract
Polyphenols have a variety of physiological activities, including antioxidant, antimicrobial, and anti-inflammatory properties. However, their applications are often limited because due to the instability of polyphenols. Encapsulation technologies can be employed to overcome these problems and increase the utilization of polyphenols. In this article, the utilization of protein-based nanoparticles for encapsulating polyphenols is reviewed due to their good biocompatibility, biodegradability, and functional attributes. Initially, the various kinds of animal and plant proteins available for forming protein nanoparticles are discussed, as well as the fabrication methods that can be used to assemble these nanoparticles. The molecular interaction mechanisms between proteins and polyphenols are then summarized. Applications of protein-based nanoparticles for encapsulating polyphenols are then discussed, including as nutrient delivery systems, in food packaging materials, and in the creation of functional foods. Finally, areas where further research is need on the development, characterization, and application of protein-based polyphenol-loaded nanoparticles are highlighted.

New natural pro-inflammatory cytokines (TNF-α, IL-6 and IL-1β) and iNOS inhibitors identified from Penicillium polonicum through in vitro and in vivo studies. Int Immunopharmacol 2023; 117:109940. [PMID: 37012863 DOI: 10.1016/j.intimp.2023.109940] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 02/11/2023] [Accepted: 02/23/2023] [Indexed: 03/12/2023]
Abstract
Overexpression of pro-inflammatory cytokines and iNOS have been found to be concomitant with several chronic inflammatory diseases and hence targeting their inhibition would be a useful therapy for inflammation. In view of this, study on discovery of natural pro-inflammatory cytokines inhibitory lead molecules from Penicillium polonicum, an endophytic fungus isolated from the fresh fruits of Piper nigrum was performed. When the culture broth extract of P. polonicum (EEPP) was subjected to LPS-induced cytokines expression (ELISA in RAW 264.7 cells), it exhibited inhibition of TNF-α, IL-6 and IL-1β and this encouraged us to do chemical investigation on EEPP to explore the bioactive components. Four compounds isolated and characterised as 3,5-di-tert-butyl-4-hydroxy-phenyl propionic acid (1), 2,4-di-tert-butyl phenol (2), indole 3-carboxylic acid (3) and tyrosol (4) were tested for their effect on the production of TNF-α, IL-1β and IL-6 in RAW 264.7 cells (ELISA). All the compounds exhibited a highly significant (P < 0.0001) inhibition effect, particularly against IL-1β (IC50: 4-0.91 μM, 1-2.81 μM, 3-4.38 μM, and 2-5.54 μM). Tyrosol (4) was most active with IC50 values of 0.91, 2.67 and 4.60 μM against IL-1β, IL-6 and TNF-α, respectively. On observing the potential activity of the compounds, two compositions C1 and C2 were prepared by mixing equimolar concentrations of compounds 1, 2, 3 & 4 (C1) and compounds 1, 2, 3, 4 & piperine (C2) in equal ratio. A synergistic effect was observed with C1 exhibiting potential suppression of IL-6 secretion (IC50 1.91 μM) and C2 against IL-1β (IC50 5.98 μM). Also, the individual compounds and C1 were effective in controlling iNOS expressions in RAW 264.7 cells (RTPCR). Further, the in vivo performance of the compounds and compositions were studied under two in vivo inflammatory models (LPS-induced endotoxaemia and carrageenan-induced paw oedema). Compounds 1, 2, 3, 4, C1 and C2 at 50 mg/kg oral dose showed a significant control over the LPS-stimulated TNF-α, IL-1β and IL-6 levels in plasma. C1, C2 and 1 exhibited > 50% pan-cytokine inhibition effect. Under the carrageenan-induced anti-inflammatory model, a significant reduction in the paw oedema measured in terms of the difference in the paw thickness was observed. Further, attenuation of pro-inflammatory cytokines levels following ELISA and RT-PCR experiments in the paw tissue homogenate was in agreement with paw thickness results. All compounds and C1 decreased the iNOS gene expression levels, and also the MPO activity and NO production in the paw tissue homogenate with tyrosol (4) as the most active molecule. Further, the mechanism of action was explored by testing the effect of the compounds on the expression of inflammatory markers using western blot analysis (in vitro). They were found to regulate the expression of pro-form and matured-form of IL-1β by inhibiting NFκB. Also, the compounds reduced the translocation of the NF-κB subunit p65 to the nucleus. Thus, compounds 3,5-di-tert-butyl-4-hydroxy-phenyl propionic acid (1), 2,4-di-tert-butyl phenol (2), indole 3-carboxylic acid (3) and tyrosol (4) are reported as new natural multiple pro-inflammatory cytokines inhibitory leads. The interesting results of C1 might lay a footing for the development of a new anti-inflammatory composition.

Abstract
Penazaphilones J–L (1–3), three new hydrophilic azaphilone pigments, as well as six known compounds, were discovered from the filamentous fungus Penicillium sclerotiorum cib-411. Compounds 1–3 were structurally elucidated by the detailed interpretation of their 1D and 2D NMR spectroscopic data. Compound 1 is an unprecedented hybrid of an azaphilone and a glycerophosphate choline. Compounds 2 and 3 each contain an intact amino acid moiety. The bioassay showed that compound 3 exhibited significant anti-inflammatory activity. Concretely, compound 3 significantly suppressed the NO production, the expression levels of COX-2, IL-6, IL-1β, and iNOS mRNA in LPS-stimulated RAW264.7 cells. Moreover, treatment of compound 3 prevented the translocation of NF-κB through inhibiting the phosphorylation of PI3K, PDK1, Akt, and GSK-3β. Thus, the inhibition of compound 3 against LPS-induced inflammation should rely on its inactivation on NF-κB.

Abstract
Traditionally in Northern China, Acer truncatum leaves (ATL) have been used as herbal tea, now consumed worldwide. Few studies have reported ATL metabolites from different areas and their correlation with the environment. Thus, metabolomic analyses were conducted on ATL collected from twelve locations throughout four environmental zones in Northern China to understand the phytochemical differences with regards to environmental conditions. Sixty-four compounds, mostly flavonoids (FLAs) and gallic acid-containing natural products (GANPs), were characterized, including 34 previously unreported constituents from A. truncatum. Twenty-two markers were useful to differentiate ATL from the four environmental zones. Humidity, temperature, and sunshine duration are the predominant factors affecting FLAs and GANPs levels. Sunshine duration was positively correlated with eriodictyol (r = 0.994, p < 0.01), and humidity negatively with epicatechin gallate (r = -0.960, p < 0.05). These findings provide insights into ATL phytochemistry, aiding cultivation of A. truncatum tea with higher potential health benefits.

Abstract
Lactobacillus strains fermentation of broccoli as a good source of bioactive peptides has not been fully elucidated. In this work, the peptide composition of broccoli fermented by L. plantarum A3 and L. rhamnosus ATCC7469 was analyzed by peptidomics to study the protein digestion patterns after fermentation by different strains. Results showed that water-soluble proteins such as rubisco were abundant sources of peptides, which triggered the sustained release of peptides as the main target of hydrolysis. In addition, 17 novel anti-inflammatory peptides were identified by virtual screening. Among them, SIWYGPDRP had the strongest ability to inhibit the release of NO from inflammatory cells at a concentration of 25 μM with an inhibition rate of 52.32 ± 1.48%. RFR and KASFAFAGL had the strongest inhibitory effects on the secretion of TNF-α and IL-6, respectively. At a concentration of 25 μM, the corresponding inhibition rates were 74.61 ± 1.68% and 29.84 ± 0.63%, respectively. Molecular docking results showed that 17 peptides formed hydrogen bonds and hydrophobic interactions with inducible nitric oxide synthase (iNOS). This study is conducive to the high-value utilization of broccoli and reduction of the antibiotic use.

Abstract
Despite the health benefits associated with the ingestion of the bioactive compounds in cocoa, the high concentrations of polyphenols and methylxanthines in the raw cocoa beans negatively influence the taste, confer the astringency and bitterness, and affect the stability and digestibility of the cocoa products. It is, therefore, necessary to process cocoa beans to develop the characteristic color, taste, and flavor, and reduce the astringency and bitterness, which are desirable in cocoa products. Processing, however, affects the composition and quantities of the bioactive compounds, resulting in the modification of the health-promoting properties of cocoa beans and chocolate. In this advanced review, we sought to better understand the effect of cocoa's transformational process into chocolate on polyphenols and methylxanthine and the mechanism of action of the original flavanols and methylxanthines. More data on the cocoa processing effect on cocoa bioactives are still needed for better understanding the effect of each processing step on the final polyphenolic and methylxanthine composition of chocolate and other cocoa products. Regarding the mechanisms of action, theobromine acts through the modulation of the fatty acid metabolism, mitochondrial function, and energy metabolism pathways, while flavanols mainly act though the protein kinases and antioxidant pathways. Both flavanols and theobromine seem to be involved in the nitric oxide and neurotrophin regulation.

Abstract
Licania rigida Benth has been evaluated as an alternative drug to treat diseases associated with inflammatory processes. This study evaluated the anti-inflammatory effects of aqueous and hydroalcoholic leaf extracts of L. rigida with inflammation induced by lipopolysaccharides in in vitro and in vivo inflammation models. The phytochemical profile of the extracts, analyzed by ultra-fast liquid chromatography coupled with tandem mass spectrometry, revealed the presence of gallic and ellagic acids in both extracts, whereas isovitexin, ferulate, bulky amino acids (e.g., phenylalanine), pheophorbide, lactic acid, and pyridoxine were detected in the hydroalcoholic extract. The extracts displayed the ability to modulate in vitro and in vivo inflammatory responses, reducing approximately 50% of pro-inflammatory cytokine secretion (TNF-α, IL-1β, and IL-6), and inhibiting both NO production and leukocyte migration by approximately 30 and 40% at 100 and 500 µg/mL, respectively. Overall, the results highlight and identify, for the first time, the ability of L. rigida leaf extract to modulate inflammatory processes. These data suggest that the leaf extracts of this plant have potential in the development of herbal formulations for the treatment of inflammation.

In this article, we investigated the anti-inflammatory effects of silibinin combined with capsaicin in lipopolysaccharide (LPS)-induced RAW264.7 cells. The results showed that silibinin combined with capsaicin strongly inhibited LPS-induced nitric oxide (NO), tumor necrosis factor-α (TNF-α), Interleukin-6 (IL-6), and COX-2. Moreover, silibinin combined with capsaicin potently inhibited nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways. The results of the present study indicate that silibinin combined with capsaicin effectively inhibits inflammation.

Abstract
AIMS Atopic dermatitis (AD) is an inflammatory chronic disease which severely interferes the life of patients. Hence, there is a great need for new therapies. Hyaluronic acid (HA) is an effective potential inflammation modifier; however, there is limited information about their implementation in inflammation therapies. This study aimed to evaluate the anti-inflammatory activities of HA and the influence of its molecular weight. MAIN METHODS Male C57BL/6 J mice were stimulated by 2,4-dinitrofluorobenzene to induce AD-like symptoms and immune response. The skin lesions and histopathological change, as well as levels of inflammatory factors were evaluated. RAW 264.7 mouse macrophages were treated with lipopolysaccharides (LPS) to induce inflammation. NO, IL-6, and TNF-α levels were detected through ELISA kits. KEY FINDINGS DNFB challenge induced mice AD symptoms including epidermal thickening, mast cell infiltration, Th2/Th1 immune response, skin lesions IL-4 and IFN-γ, and serum IgE elevation. HA treatment ameliorated such symptoms through the inhibition of PI3K/Akt signaling pathway. LPS induction stimulated the secretion of NO, IL-6, and TNF-α in RAW 264.7 cells, while HA pre-treatment reduced the concentration of the cytokines in cell supernatants. SIGNIFICANCE These findings give clear insight into the interaction between HA and inflammatory response, which can help guiding the utilization of HA in the AD therapies.

Abstract
Glasswort (Salicornia herbacea L.) is a halophyte that exhibits antioxidant and antidiabetic effects. Only a few studies have been conducted on its antioxidant effects. Here, we isolated an antioxidant using an activity-based purification method, and the resulting compound was identified as (9Z,11E)-13-Oxooctadeca-9,11-dienoic acid (13-KODE). We investigated its ability to suppress inflammatory responses and the molecular mechanisms underlying these abilities using lipopolysaccharide-stimulated RAW 264.7 macrophage cells. We studied the anti-inflammatory effects of 13-KODE derived from S. herbacea L on RAW 264.7 macrophages. 13-KODE inhibited lipopolysaccharide (LPS)-induced nitric oxide (NO) production by suppressing inducible NO synthase and suppressed LPS-induced tumor necrosis factor and interleukin-1β expression in RAW 264.7 macrophages. LPS-mediated nuclear localization of NF-κB and mitogen-activated protein kinase activation were inhibited by 13-KODE. 13-KODE significantly reduced LPS-induced production of reactive oxygen species and increased the expression of nuclear factor erythroid-2 like 2 (Nfe2I2) and heme oxygenase 1. Overall, our results indicate that 13-KODE may have potential for treating inflammation.
