Abstract
Pain management has been a severe public health issue throughout the world. Acute pain if not treated at the appropriate time can lead to chronic pain that can cause psychological and social distress. Nothing can be more rewarding than treating pain successfully for a physician. However, the use of chemical NSAIDs and opiate drugs has taken a toll on the patients with their unavoidable side effects. This study intends to explore the potential to treat pain by inhibiting nociception and inflammation with a safer, non-addictive, effective, and low-cost alternative agent from a natural source, visnagin. In vivo studies have been conducted using male Swiss albino mice as models for this research. Nociception was induced using different chemical and thermal stimuli such as acetic acid, glutamate, capsaicin, and formalin. To check for the anti-inflammatory properties, carrageenan was used to induce inflammation and the activity was assayed using peritoneal cavity leukocyte infiltration analysis and pro-inflammatory cytokine level comparison with the supplementation of visnagin at three different dosages. The findings of this study revealed that the visnagin treatment effectively attenuated the acetic acid-induced writhing response, glutamate-induced paw licking numbers, capsaicin-induced pain response, and formalin-induced biphasic licking incidences in the experimental mice models. Furthermore, the visnagin treatment remarkably suppressed the carrageenan-induced inflammation in mice, which is evident from the decreased leukocytes, mononuclear, and polymorphonuclear cell numbers in the mice. The levels of cytokines such as TNF-α, IL-1β, and IL-6 were effectively reduced by the visnagin treatment in the experimental mice. The results of open field test proved that the visnagin showed a better locomotor movement in the experimental mice. These results provided evidence for the potential activity of the visnagin against inflammatory and nociceptive responses in the mice.

Abstract
The unsatisfactory effects of conventional bactericides and antimicrobial resistance have increased the challenges in managing plant diseases caused by bacterial pests. Here, we report the successful design and synthesis of benzofuran derivatives using benzofuran as the core skeleton and splicing the disulfide moieties commonly seen in natural substances with antibacterial properties. Most of our developed benzofurans displayed remarkable antibacterial activities to frequently encountered pathogens, including Xanthomonas oryzae pv oryzae (Xoo), Xanthomonas oryzae pv oryzicola (Xoc), and Xanthomonas axonopodis pv citri (Xac). With the assistance of the three-dimensional quantitative constitutive relationship (3D-QSAR) model, the optimal compound V40 was obtained, which has better in vitro antibacterial activity with EC50 values of 0.28, 0.56, and 10.43 μg/mL against Xoo, Xoc, and Xac, respectively, than those of positive control, TC (66.41, 78.49, and 120.36 μg/mL) and allicin (8.40, 28.22, and 88.04 μg/mL). Combining the results of proteomic analysis and enzyme activity assay allows the antibacterial mechanism of V40 to be preliminarily revealed, suggesting its potential as a versatile bactericide in combating bacterial pests in the future.

Abstract
Khellin and visnagin furanochromones were recently reported as potential new bioherbicides with phytotoxic activities comparable to those of some commercially available herbicides. In this study, we examined the effect of O-alkylation and O-arylalkylation of both khellin and visnagin on its effect on herbicidal and antifungal activity. Synthetic analogues included O-demethyl khellin and visnagin, acetylated O-demethyl khellin and visnagin, O-benzylated demethyl khellin and visnagin, four O-demethyl alkylated khellin analogues, and six O-demethyl alkylated visnagin analogues, many of which are reported here for the first time. Both acetate analogues of khellin and visnagin indicated more activity as herbicides on Lemna pausicostata than visnagin, with IC50 values of 71.7 and 77.6 μM, respectively. Complete loss of activity for all O-alkyl analogues with a carbon chain length of greater than 14 carbons was observed. The O-demethyl butylated visnagin analogue was the most active compound with an IC50 of 47.2 μM against L. pausicostata. O-Demethyl ethylated analogues of both khellin and visnagin were as effective as khellin. In the antifungal bioautography bioassay against Colletotrichum fragariae at 100 μg, the only active O-alkyl and O-arylalkyl analogues were O-ethylated, O-butylated, and O-benzylated visnagin analogues with zones of inhibition of 10, 9, and 9 mm, respectively, an effect comparable to that of visnagin and khellin.

Discovery of New Heterocyclic/Benzofuran Hybrids as Potential Anti-Inflammatory Agents: Design, Synthesis, and Evaluation of the Inhibitory Activity of Their Related Inflammatory Factors Based on NF-κB and MAPK Signaling Pathways. Int J Mol Sci 2023; 24:ijms24043575. [PMID: 36834992 PMCID: PMC9958778 DOI: 10.3390/ijms24043575] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 12/01/2022] [Accepted: 01/30/2023] [Indexed: 02/12/2023] Open
Abstract
NF-κB and MAPK are classic inflammation signaling pathways which regulate inflammation signal transmission and induce the expression of many inflammatory factors. Based on the potent anti-inflammatory activity of benzofuran and its derivatives, several new heterocyclic/benzofuran hybrids were first designed and synthesized by molecular hybridization. Their structure was confirmed by 1H NMR, 13C NMR, HRMS or X-single crystal diffraction. The anti-inflammatory activity of these new compounds was screened by compounds; compound 5d exhibited an excellent inhibitory effect on the generation of NO (IC50 = 52.23 ± 0.97 μM), and low cytotoxicity (IC50 > 80 μM) against the RAW-264.7 cell lines. To further elucidate the possible anti-inflammatory mechanisms of compound 5d, the hallmark protein expressions of the NF-κB and MAPK pathways were studied in LPS-stimulated RAW264.7 cells. The results indicate that compound 5d not only significantly inhibits the phosphorylation levels of IKKα/IKKβ, IKβα, P65, ERK, JNK and P38 in the classic MAPK/NF-κB signaling pathway in a dose-dependent manner, but also down-regulates the secretion of pro-inflammatory factors such as NO, COX-2, TNF-α and IL-6. Further, the in vivo anti-inflammatory activity of compound 5d indicated that it could regulate the involvement of neutrophils, leukocytes and lymphocytes in inflammation processes, and reduce the expression of IL-1β, TNF-α and IL-6 in serum and tissues. These results strongly suggest that the piperazine/benzofuran hybrid 5d has a good potential for developing an anti-inflammatory lead compound, and the anti-inflammatory mechanism might be related to the NF-κB and MAPK signaling pathways.

Abstract
BACKGROUND Lead (Pb) is an environmental pollutant causing serious health problems, including impairment of reproduction. Visnagin (VIS) is a furanochromone with promising antioxidant and anti-inflammatory effects; however, its protective efficacy against Pb toxicity has not been investigated. OBJECTIVE This study evaluated the protective effect of VIS on Pb reproductive toxicity, impaired steroidogenesis and spermatogenesis, oxidative stress and inflammation. METHODS Rats received VIS (30 or 60 mg/kg) and 50 mg/kg lead acetate for 3 weeks and blood and testes samples were collected. RESULTS Pb intoxication impaired the pituitary-testicular axis (PTA) manifested by the decreased serum levels of gonadotropins and testosterone. Pb decreased sperm count, motility and viability, increased sperm abnormalities, and downregulated the steroidogenesis markers StAR, CYP17A1, 3β-HSD and 17β-HSD in the testis of rats. VIS significantly increased serum gonadotropins and testosterone, alleviated sperm parameters and upregulated steroidogenesis. In addition, VIS decreased pro-inflammatory cytokines, testicular lipid peroxidation and DNA fragmentation, downregulated Bax, and enhanced antioxidants and Bcl-2. CONCLUSION These results demonstrate the protective effect of VIS against Pb reproductive toxicity in rats. VIS improved serum gonadotropins and testosterone, enhanced steroidogenesis and spermatogenesis, and attenuated oxidative injury, inflammation and apoptosis. Therefore, VIS is a promising candidate for the protection against Pb-induced reproduction impairment.

Abstract
Visnagin is a furanochromone and one of the main compounds of Ammi visnaga L. that had been used to treat nephrolithiasis in Ancient Egypt. Nowadays, visnagin was widely used to treat angina pectoris, urolithiasis and hypertriglyceridemia. The potential mechanisms of visnagin involved in inflammation and cardiovascular disease were also identified. But the protective effect of visnagin on myocardial ischemia/reperfusion injury has not been confirmed. Our aim was, for the first time, to investigate the potential protective effect of visnagin on cardiac function after myocardial ischemia-reperfusion injury in a rat model, and to identify its underlying mechanism involving the inhibition of apoptosis and induction of autophagy. Thirty SD rats were randomly divided into sham group, ischemia/reperfusion group (IR), ischemia/reperfusion with visnagin (IR + visnagin) group. Myocardial ischemia/Reperfusion injury model was established. Hemodynamic measurements and echocardiography were used to analyze cardiac function, TUNEL staining and caspase activity, LC3 dots were detected with immunofluorescence staining, LC3 expression was evaluated by western blot analysis, transmission electron microscopy (TEM) was used to detect autophagosomes. Compared with the sham group and visnagin group, the cardiac dysfunction, LC3II, autophagy flow in the IR+ visnagin group increased significantly (P<0.01), but the activity of caspase-3 and caspase-9 and the apoptotic in the IR + visnagin group decreased significantly (P<0.01). In conclusion, visnagin may play a protective role in ischemia/reperfusion injury by inducing autophagy and reducing apoptosis.

Abstract
The Keap1/Nrf2/ARE system is a central defensive mechanism against oxidative stress which plays a key role in the pathogenesis and progression of many diseases. Nrf2 is a redox-sensitive transcription factor controlling a variety of downstream antioxidant and cytodefensive genes. Nrf2 has a powerful anti-inflammatory activity mediated via modulating NF-κB. Therefore, pharmacological activation of Nrf2 is a promising therapeutic strategy for the treatment/prevention of several diseases that are underlined by both oxidative stress and inflammation. Coumarins are natural products with promising pharmacological activities, including antioxidant, anticancer, antimicrobial, and anti-inflammatory efficacies. Coumarins are found in many plants, fungi, and bacteria and have been widely used as complementary and alternative medicines. Some coumarins have shown an ability to activate Nrf2 signaling in different cells and animal models. The present review compiles the research findings of seventeen coumarin derivatives of plant origin (imperatorin, visnagin, urolithin B, urolithin A, scopoletin, esculin, esculetin, umbelliferone, fraxetin, fraxin, daphnetin, anomalin, wedelolactone, glycycoumarin, osthole, hydrangenol, and isoimperatorin) as antioxidant and anti-inflammatory agents, emphasizing the role of Nrf2 activation in their pharmacological activities. Additionally, molecular docking simulations were utilized to investigate the potential binding mode of these coumarins with Keap1 as a strategy to disrupt Keap1/Nrf2 protein-protein interaction and activate Nrf2 signaling.
