Abstract
Sanghuangporus sanghuang is a large wood-decaying mushroom highly valued in traditional Chinese medicine due to its medicinal properties, including hypoglycemic, antioxidant, antitumor, and antibacterial properties effects. Its key bioactive compounds include flavonoids and triterpenoids. Specific fungal genes can be selectively induced by fungal elicitors. To investigate the effect of fungal polysaccharides derived from Perenniporia tenuis mycelia on the metabolites of S. sanghuang, we conducted metabolic and transcriptional profiling with and without elicitor treatment (ET and WET, respectively). Correlation analysis showed significant differences in triterpenoid biosynthesis between the ET and WET groups. In addition, the structural genes associated with triterpenoids and their metabolites in both groups were verified using quantitative real-time polymerase chain reaction (qRT-PCR) and high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Through metabolite screening, three triterpenoids were identified: betulinol, betulinic acid, and 2-hydroxyoleanolic acid. Excitation treatment increased the level of betulinic acid by 2.62-fold and 2-hydroxyoleanolic acid by 114.67-fold compared to WET. The qRT-PCR results of the four genes expressed in secondary metabolic pathways, defense gene activation, and signal transduction showed significant variation between the ET and WET groups. Overall, our study suggests that the fungal elicitor induced the aggregation of pentacyclic triterpenoid secondary metabolites in S. sanghuang.

Abstract
Acute Lung Injury (ALI) is a critical medical condition that induces the injury into the lung tissue, resulting in decreased the oxygen levels in the circulation and finally causes the respiratory failure. In this study, we try to made effort for scrutinized the preventive effect of gossypin against lipopolysaccharide (LPS) induced lung inflammation and explore the underlying mechanism. LPS (7.5 mg/kg) was used for induction the lung inflammation in the rats and rats were received the oral administration of gossypin (5, 10 and 15 mg/kg). The wet to dry weight lung ratio and lung index were estimated. The bronchoalveolar lavage fluid (BALF) were collected to determination the inflammatory cells, total protein, macrophages and neutrophils. ELISA kits were used for the estimation of antioxidant, inflammatory cytokines, inflammatory parameters, nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) parameters. Finally, we used the lung tissue for scrutinize the alteration in the lung histopathology. Gossypin treatment significantly (p < .001) reduced the W/D ratio of lung tissue and lung index. Gossypin significantly (p < .001) decreased the total cells, neutrophils, macrophages and total protein in BALF. It is also altered the level of inflammatory cytokines, antioxidant and inflammatory parameters, respectively. Gossypin improved the level of Nrf2 and HO-1 at dose dependent manner. Gossypin treatment remarkably enhance the ALI severity via balancing the structural integrity of lung tissue, decrease the thickness of the alveolar wall, decline the pulmonary interstitial edema, and number of inflammatory cells in the lung tissue. Gossypin is a promising agent for the treatment of LPS induced lung inflammation via altering Nrf2/HO-1 and NF-κB.

Abstract
The traditional Chinese medicine Xanthium sibiricum Patrin ex Widder is used to treat wind-cold headache, nasal congestion, nasal discharge, allergic rhinitis, sinusitis, urticaria, and arthritis. Our previous studies found that sesquiterpene lactones, the main bioactive constituents of X. sibiricum, relieved airway inflammation in an asthma mouse model. To obtain active sesquiterpenes, five undescribed ones, including a pair of eremophilanes and three xanthanolides, together with eight known xanthanolides were isolated from X. sibiricum. Their structures were identified by IR, UV, HR-ESI-MS and NMR spectroscopic data, and their absolute configurations were determined by X-ray crystallographic diffraction analysis and the comparison between their experimental and calculated electronic circular dichroism. All isolated compounds were evaluated for their inhibitory effects on nitric oxide production, and Tnf-α, Il-1β, and Il-6 mRNA expression induced by lipopolysaccharide in the macrophage cell line RAW264.7. Further investigation showed that xanthsibiriolide and 11β-hydroxyl-13-chloro-8-epi-xanthatin exerted their anti-inflammatory effects by inhibiting the PI3K/AKT/mTOR signaling pathway. Analysis of the structure-activity relationships indicated that the α,β-unsaturated lactone ring and the 1,5-epoxide group might be the bioactive groups of xanthanolides, and these results provide a basis for further exploration of sesquiterpene-type lead compounds with anti-inflammatory activity.

Abstract
Acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) is one of the leading pulmonary inflammatory disorders causing significant morbidity and mortality. Vincamine is a novel phytochemical with promising anti-inflammatory properties. In the current work, the protective effect of vincamine was studied in vitro (Raw 264.7 macrophages) and in vivo against lipopolysaccharide (LPS) induced ALI in Swiss albino mice. Vincamine significantly reduced nitrite and TNF-α release from the LPS stimulated macrophages and increased the levels of IL-10, indicating potent anti-inflammatory effects. It was observed that vincamine at the dose of 40 mg/kg, significantly reduced LPS induced inflammatory cell count in blood and in bronchoalveolar lavage (BAL) fluid. Further, vincamine exerted potent suppression of inflammation by reducing the expression of proinflammatory cytokines, while significantly increased (p < 0.001) the expression of anti-inflammatory cytokine (IL-10 and IL-22). Interestingly, histological changes were reversed in vincamine treated groups in a dose-dependent manner. Immunohistochemical analysis revealed significantly enhanced expression of NF-κB, TNF-α and COX-2 while reduced expression of Nrf-2 in disease control group, which were significantly (p < 0.001) ameliorated by vincamine. We, to the best of our knowledge, report for the first time that vincamine possesses protective potential against LPS induced inflammation and oxidative stress, possibly by inhibiting the NF-κB cascade, while positively regulating the Nrf-2 pathway. These findings are of potential relevance for COVID-19 management concerning the fact that lung injury and ARDS are its critical features.

Abstract
A chemical investigation on the fermentation products of Sanghuangporus sanghuang led to the isolation and identification of fourteen secondary metabolites (1-14) including eight sesquiterpenoids (1-8) and six polyphenols (9-14). Compounds 1-3 were sesquiterpenes with new structures which were elucidated based on NMR spectroscopy, high resolution mass spectrometry (HRMS) and electronic circular dichroism (ECD) data. All the isolates were tested for their stimulation effects on glucose uptake in insulin-resistant HepG2 cells, and cellular antioxidant activity. Compounds 9-12 were subjected to molecular docking experiment to primarily evaluate their anti-coronavirus (SARS-CoV-2) activity. As a result, compounds 9-12 were found to increase the glucose uptake of insulin-resistant HepG2 cells by 18.1%, 62.7%, 33.7% and 21.4% at the dose of 50 μmol·L-1, respectively. Compounds 9-12 also showed good cellular antioxidant activities with CAA50 values of 12.23, 23.11, 5.31 and 16.04 μmol·L-1, respectively. Molecular docking between COVID-19 Mpro and compounds 9-12 indicated potential SARS-CoV-2 inhibitory activity of these four compounds. This work provides new insights for the potential role of the medicinal mushroom S. sanghuang as drugs and functional foods.

Abstract
Chronic inflammation induces autoimmune disorders and chronic diseases. Several natural products activate nuclear factor erythroid 2-related factor 2 (Nrf2) signaling, attenuating inflammatory responses. Ergosta-7,9(11),22-trien-3β-ol (EK100) isolated from Cordyceps militaris showed anti-inflammatory and antioxidative activity, but those mechanisms are still unclear. This study is the first to investigate EK100 on antioxidant Nrf2 relative genes expression in LPS-stimulated macrophage-like cell lines. The results showed that EK100 reduced IL-6 (interleukin-6) and tumor necrosis factor-α production. EK100 also attenuated a mitogen-activated protein kinase/activator protein-1 (MAPK/AP-1) pathway and interleukin-6/Janus kinase/signal transducer and activator of transcription (IL-6/JAK/STAT) pathway in LPS-stimulated cells. Toll-like receptor 4 (TLR4) inhibitor CLI-095 and MAPK inhibitors can synergize the anti-inflammatory response of EK100 in LPS-stimulated cells. Moreover, EK100 activated Nrf2/HO-1 (heme oxygenase-1) signaling in LPS-stimulated murine macrophage-like RAW 264.7 cells, murine microglial BV2 cells, and human monocytic leukemia THP-1 cells. However, Nrf2 small interfering RNA (Nrf2 siRNA) reversed EK100-induced antioxidative proteins expressions. In conclusion, EK100 showed anti-inflammatory responses via activating the antioxidative Nrf2/HO-1 signaling and inhibiting TLR4 related MAPK/AP-1 induced IL-6/JAK/STAT pathways in the LPS-stimulated cells in vitro. The results suggest EK100 acts as a novel antioxidant with multiple therapeutic targets that can potentially be developed to treat chronic inflammation-related diseases.

Abstract
Liver damage induced by paracetamol overdose is the main cause of acute liver failure worldwide. In order to study the hepatoprotective effect of Sanghuangporus sanghuang mycelium (SS) on paracetamol-induced liver injury, SS was administered orally every day for 6 days in mice before paracetamol treatment. SS decreased serum aminotransferase activities and the lipid profiles, protecting against paracetamol hepatotoxicity in mice. Furthermore, SS inhibited the lipid peroxidation marker malondialdehyde (MDA), hepatic cytochrome P450 2E1 (CYP2E1), and the histopathological changes in the liver and decreased inflammatory activity by inhibiting the production of proinflammatory cytokines in paracetamol-induced acute liver failure. Moreover, SS improved the levels of glutathione (GSH), superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase in the liver. Significantly, SS diminished mitogen-activated protein kinase (MAPK), Toll-like receptor 4 (TLR4), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), and the nuclear factor-kappa B (NF-κB) axis, as well as upregulated the Kelch-like ECH-associated protein 1 (Keap1)/erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway, in paracetamol-induced mice. SS mainly inhibited the phosphorylation of the liver kinase B1 (LKB1), Ca2+/calmodulin-dependent kinase kinase β (CaMKKβ), and AMP-activated protein kinase (AMPK) protein expression. Furthermore, the protective effects of SS on paracetamol-induced hepatotoxicity were abolished by compound C, an AMPK inhibitor. In summary, we provide novel molecular evidence that SS protects liver cells from paracetamol-induced hepatotoxicity by inhibiting oxidative stress and inflammation.

Imperatorin Interferes with LPS Binding to the TLR4 Co-Receptor and Activates the Nrf2 Antioxidative Pathway in RAW264.7 Murine Macrophage Cells. Antioxidants (Basel) 2021; 10:antiox10030362. [PMID: 33673673 PMCID: PMC7997471 DOI: 10.3390/antiox10030362] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 02/12/2021] [Accepted: 02/22/2021] [Indexed: 12/15/2022] Open
Abstract
Imperatorin (IMP) could downregulate several inflammatory transcription factor signaling pathways. Some studies have pointed out that IMP could interfere with toll-like receptor 4 (TLR4) signaling. This study evaluates how IMP interferes with the TLR4 co-receptors signaling through the protein-ligand docking model, Western blotting, immunofluorescence (IF), and atomic force microscopy (AFM) assays in lipopolysaccharide (LPS) stimulated macrophage-like RAW264.7 cells in vitro. The results of the protein-ligand docking demonstrate that IMP interferes with LPS binding to the LPS-binding protein (LBP), the cluster of differentiation 14 (CD14), and the toll-like receptor 4/myeloid differentiation factor 2 (TLR4/MD-2) co-receptors in LPS-stimulated RAW264.7 cells. Compared with TLR4 antagonist CLI-095 or dexamethasone, IMP could suppress the protein expressions of LBP, CD14, and TLR4/MD-2 in LPS-stimulated cells. Furthermore, the three-dimensional (3D) image assay of the AFM showed IMP could prevent the LPS-induced morphological change in RAW264.7 cells. Additionally, IMP could activate the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway, and it increased the antioxidative protein expression of heme oxygenase-1 (HO-1), superoxidase dismutase (SOD), and catalase (CAT). Our results are the first to reveal that the anti-inflammatory effect of IMP interferes with LPS binding to TLR4 co-receptor signaling and activates the antioxidative Nrf2 signaling pathway.

Abstract
Although pipoxolan (PIPO) is a smooth muscle relaxant, its anti-inflammatory capability has not been studied. Therefore, we investigated the anti-inflammatory molecular mechanisms of PIPO in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. In this study, we used the MTT assay to evaluate the cytotoxicity, applied the enzyme-linked immunosorbent assay to determine the inflammatory cytokines, and performed Western blotting to assess protein expression. The results showed that PIPO significantly inhibited cytokine production, including nitric oxide, prostaglandin E2 , tumor necrosis factor-α, and interleukin-6. PIPO also suppressed the pro-inflammatory mediator expression with inducible nitric oxide synthase and cyclooxygenase-2. Moreover, PIPO prohibited the multiple inflammatory transcription factor pathways, including inhibitor kappa B/nuclear factor of the κ light chain enhancer of B cells (NF-κB), mitogen-activated protein kinase/activator protein-1 (AP-1), Janus kinase/signal transducer and activator of transcription (STAT), and toll-like receptor 4 (TLR4)/serine/threonine kinase (AKT). Besides, PIPO effectively activated the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 antioxidative pathway. Collectively, PIPO may attenuate the inflammatory effects via influencing the LPS/TLR4 receptor binding; suppress the expression of anti-inflammatory transcription factors NF-κB, AP-1, and STAT; and activating the antioxidative transcription factor Nrf2 in LPS-stimulated mouse RAW 264.7 cells.

Cordyceps cicadae Mycelia Ameliorate Cisplatin-Induced Acute Kidney Injury by Suppressing the TLR4/NF- κB/MAPK and Activating the HO-1/Nrf2 and Sirt-1/AMPK Pathways in Mice. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:7912763. [PMID: 32089779 PMCID: PMC7026739 DOI: 10.1155/2020/7912763] [Citation(s) in RCA: 80] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 12/20/2019] [Accepted: 01/11/2020] [Indexed: 12/14/2022]
Abstract
Acute kidney injury (AKI) is a common clinical problem, characterized by a sudden loss of renal function, a high risk of death, and the eventual development of renal fibrosis and renal failure. Cordyceps cicadae is a traditional Chinese medicine with the potential function of kidney protection. We analyze two sputum extracts, a water extract (WCC), and an ethanol extract (ECC), to assess the potential of treating AKI in an animal model of kidney injury induced by cisplatin. A nephrotoxic mouse model was first established by intraperitoneal injection of cisplatin. Subsequently, WCC and ECC were orally administered in these mice. The results show that WCC and ECC significantly alleviated cisplatin-induced AKI renal histological changes, serum creatinine (CRE) and blood urea nitrogen (BUN) production, and the levels of NO, TNF-α, IL-1β, and IL-6. The levels of malondialdehyde (MDA) and glutathione (GSH) were suppressed by administration of WCC and ECC. However, WCC treatment prevented these changes significantly better than ECC treatment. In addition, Western blot data showed that WCC attenuated the cisplatin-induced protein expression of cyclooxygenase-2 (COX-2) and inducible NO synthase (iNOS), as well as inhibiting nuclear factor-kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) activation in the kidney tissues. Furthermore, WCC greatly inhibited the expression of Toll-like receptor 4 (TLR4) and cisplatin-induced NF-κB activation, as well as dramatically increasing the production of antioxidative enzymes (i.e., superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase, nuclear factor erythroid 2-related factor 2 (Nrf2), and heme oxygenase 1 (HO-1)), silent information regulator T1 (Sirt1), and p-AMP-activated protein kinase (AMPK) in the kidney tissues. In addition, we found that WCC increased the expression levels of the autophagy-related proteins LC3B and Beclin-1; proapoptotic proteins, including cleaved caspase-3 and cleaved poly (ADP-ribose) polymerase (PARP) 1; and organic anion transporters 1 (OAT1) and 3 (OAT3) in the kidney tissues. Finally, WCC, ECC, and two bioactive compounds-adenosine and N6-(2-hydroxyethyl) adenosine (HEA)-inhibited the production of nitrite oxide (NO) and intracellular reactive oxygen species (ROS) triggered by lipopolysaccharide- (LPS-) stimulated RAW264.7 macrophages in vitro. Collectively, WCC could provide a potential therapeutic candidate for the prevention of cisplatin-induced kidney injury through the inhibition of oxidative stress and inflammation.

Abstract
"Sanghuang" is a popular fungus used as a Chinese traditional medicine. In fact, it represents a group of fungi belonging to the genus Sanghuangporus, but little is known about its origin and biogeography. The aim of this study was to characterize the molecular relationships, origin and biogeographical distribution of Sanghuangporus. The multi-locus phylogenetic analyses were used to infer the phylogenetic relationships. In addition, based on Bayesian evolutionary analysis using sequences from the internal transcribed spacer (ITS), nuclear large subunit rDNA (nLSU), translation elongation factor 1-α (EF1-α), and the largest and second largest subunits of RNA polymerase II (RPB1 and RPB2), we used a fungus fossil-based approach to gain insight into the divergence time of species in Sanghuangporus. The molecular phylogeny strongly supports the monophyly of Sanghuangporus (MP = 100%, ML = 100%, and BPP = 1.00), and 13 species are recognized in this genus. The Bayesian uncorrelated lognormal relaxed molecular clock using BEAST and reconstructed ancestral areas indicate that the maximum crown age of Sanghuangporus is approximately 30.85 million years. East Asia is the likely ancestral area (38%). Dispersal and differentiation to other continents then occurred during the late Middle Miocene and Pliocene. The ancestor of Sanghuangporus probably originated in palaeotropical Northeast Asia and covered Northeast Asia and East Africa during the Oligocene-Miocene, hosted by plants that expanded via the "Gomphotherium Landbridge." Six kinds of dispersal routes are proposed, including intercontinental dispersal events of three clades between Northeast Asia and East Africa, between East Asia and North America, and between Northeast Asia and Europe.

Ginsenoside Rh2 Ameliorates Lipopolysaccharide-Induced Acute Lung Injury by Regulating the TLR4/PI3K/Akt/mTOR, Raf-1/MEK/ERK, and Keap1/Nrf2/HO-1 Signaling Pathways in Mice. Nutrients 2018; 10:nu10091208. [PMID: 30200495 PMCID: PMC6163254 DOI: 10.3390/nu10091208] [Citation(s) in RCA: 46] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2018] [Revised: 08/16/2018] [Accepted: 08/30/2018] [Indexed: 12/19/2022] Open
Abstract
The anti-inflammatory effect of ginsenoside Rh2 (GRh2) has labeled it as one of the most important ginsenosides. The purpose of this study was to identify the anti-inflammatory and antioxidant effects of GRh2 using a lipopolysaccharide (LPS) challenge lung-injury animal model. GRh2 reduced LPS-induced proinflammatory mediator nitric oxide (NO), tumor necrosis factor-alpha, interleukin (IL)-1β, and anti-inflammatory cytokines (IL-4, IL-6, and IL-10) production in lung tissues. GRh2 treatment decreased the histological alterations in the lung tissues and bronchoalveolar lavage fluid (BALF) protein content; total cell number also reduced in LPS-induced lung injury in mice. Moreover, GRh2 blocked iNOS, COX-2, the phosphorylation of IκB-α, ERK, JNK, p38, Raf-1, and MEK protein expression, which corresponds with the growth of HO-1, Nrf-2, catalase, SOD, and GPx expression in LPS-induced lung injury. An in vivo experimental study suggested that GRh2 has anti-inflammatory effects, and has potential therapeutic efficacy in major anterior segment lung diseases.
