Abstract
Berteroin is a bioactive substance classified as an isothiocyanate found in cruciferous vegetables such as cabbage, arugula, and salad leaves. In this study, we aimed to determine whether berteroin exerts anti-inflammatory effects on human periodontal ligament cells (HPDLCs), a resident cells of periodontal tissue. Berteroin suppressed interleukin (IL)-1β or tumor necrosis factor (TNF)-α-induced chemokines (C-C motif chemokine ligand (CCL)2, CCL20, C-X-C motif chemokine ligand (CXCL)10, IL-8, and IL-6) production and intercellular adhesion molecule (ICAM)-1 expression in HPDLCs. In addition, berteroin inhibited phosphorylation of IκB kinase (IKK)- α/ β, nuclear factor (NF)- κB p65, and IκB- α and degradation of IκB- α in the NF-κB pathway induced by IL-1 β or TNF- α stimulation. Moreover, berteroin could inhibit signal transducer and activator of transcription (STAT)3 phosphorylation in TNF- α -stimulated HPDLC. Furthermore, berteroin increased the expression of the antioxidant enzymes, heme oxygenase (HO)-1 and NAD(P)H quinone dehydrogenase (NQO)1, in IL-1 β or TNF- α -stimulated HPDLCs. These results suggest that berteroin may decrease the production of inflammatory mediators in HPDLCs by suppressing the NF-κB pathway, and may also decrease the local reactive oxygen species (ROS) production in periodontal lesions by increasing the production of antioxidant enzymes.

Abstract
OBJECTIVES Periodontitis is a chronic inflammatory disease induced by periodontal disease-causing bacteria. It has been shown that excessive immune response against bacteria is involved in periodontal tissue destruction including alveolar bone resorption. Erucin is a biologically active substance found in cruciferous plants such as arugula and is classified as an isothiocyanate. No previous studies have attempted to use erucin in the treatment of periodontitis, and there are no papers that have examined the effects of erucin on periodontal resident cells. The purpose of this study was to analyze the effects of erucin on the production of inflammatory and antioxidant mediators produced by tumor necrosis factor (TNF)-α-stimulated TR146 cells, an oral epithelial cell line, including its effects on signaling molecules. METHODS Cytokine and chemokine levels were measured by ELISA. Protein expression in TR146 cells and activations of signal transduction pathway were determined by Western blotting. RESULTS Our results indicate that erucin suppresses interleukin-6 and CXC-chemokine ligand 10 production and vascular cell adhesion molecule-1 expression in TNF-α-stimulated TR146 cells. In addition, erucin induced the production of the antioxidant enzymes, Heme Oxygenase-1 and NAD(P)H quinone dehydrogenase 1 in TR146 cells. Furthermore, erucin suppressed TNF-α-stimulated nuclear factor-κB, signal transducer and activator of transcription3, and phospho-70S6 Kinase-S6 ribosomal protein signaling pathways in TR146 cells. We have shown that erucin has anti-inflammatory effects on oral epithelial cells and also induces the production of antioxidant mediators. CONCLUSIONS These results suggest that erucin may provide a new anti-inflammatory agent that can be used in the treatment of periodontitis.

Bioaccessible Organosulfur Compounds in Broccoli Stalks Modulate the Inflammatory Mediators Involved in Inflammatory Bowel Disease. Int J Mol Sci 2024; 25:800. [PMID: 38255874 PMCID: PMC10815348 DOI: 10.3390/ijms25020800] [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: 11/27/2023] [Revised: 01/02/2024] [Accepted: 01/04/2024] [Indexed: 01/24/2024] Open
Abstract
Inflammatory diseases are strongly associated with global morbidity and mortality. Several mediators are involved in this process, including proinflammatory interleukins and cytokines produced by damaged tissues that, somehow, act as initiators of the autoreactive immune response. Bioactive compounds present in plant-based foods and byproducts have been largely considered active agents with the potential to treat or prevent inflammatory diseases, being a valuable alternative to traditional therapeutic agents used nowadays, which present several side effects. In this regard, the present research uncovers the anti-inflammatory activity of the bioaccessible fraction of broccoli stalks processed, by applying different conditions that render specific concentrations of bioactive sulforaphane (SFN). The raw materials' extracts exhibited significantly different contents of total glucosinolates (GSLs) that ranged between 3993.29 and 12,296.48 mg/kg dry weight (dw), with glucoraphanin as the most abundant one, followed by GI and GE. The indolic GSLs were represented by hydroxy-glucobrassicin, glucobrassicin, methoxy-glucobrassicin, and neo-glucobrassicin, with the two latter as the most abundant. Additionally, SFN and indole-3-carbinol were found in lower concentrations than the corresponding GSL precursors in the raw materials. When exploring the bioaccessibility of these organosulfur compounds, the GSL of all matrices remained at levels lower than the limit of detection, while SFN was the only breakdown product that remained stable and at quantifiable concentrations. The highest concentration of bioaccessible SFN was provided by the high-ITC materials (~4.00 mg/kg dw). The results retrieved on the cytotoxicity of the referred extracts evidenced that the range of supplementation of growth media tested (0.002-430.400 µg of organosulfur compounds/mL) did not display cytotoxic effects on Caco-2 cells. The obtained extracts were assessed based on their capacity to reduce the production of key proinflammatory cytokines (interleukin 6 (IL-6), IL-8, and TNF-α) by the intestinal epithelium. Most of the tested processing conditions provided plant material with significant anti-inflammatory activity and the absence of cytotoxic effects. These data confirm that SFN from broccoli stalks, processed to optimize the bioaccessible concentration of SFN, may be potential therapeutic leads to treat or prevent human intestinal inflammation.

Abstract
The aim of this study was to develop an optimal synthetic route to obtain natural (R)-8-methylsulfinyloctyl isothiocyanate ((R)-8-OITC), present in watercress, based on the "DAG methodology" as well as to evaluate its potential antioxidant and immunomodulatory effects, exploring possible signaling pathways that could be involved in an ex vivo model of murine peritoneal macrophages stimulated with LPS. Treatment with (R)-8-OITC inhibited the levels of pro-inflammatory cytokines (IL-1β, TNF-α, IL-6, IL-17 and IL-18), intracellular ROS production and expression of pro-inflammatory enzymes (COX-2, iNOS and mPGES-1) through modulation of the expression of Nrf2, MAPKs (p38, JNK and ERK) and JAK/STAT, and the canonical and non-canonical pathways of the inflammasome. Taking all these together, our results provide a rapid and cost-effective synthetic route to obtain natural (R)-8-OITC and demonstrate that it could be a potential nutraceutical candidate for managing immuno-inflammatory pathologies. Therefore, further in vivo trials are warranted.
