Exploring the pathophysiological influence of heme oxygenase-1 on neuroinflammation and depression: A study of phytotherapeutic-based modulation. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 127:155466. [PMID: 38461764 DOI: 10.1016/j.phymed.2024.155466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 02/02/2024] [Accepted: 02/18/2024] [Indexed: 03/12/2024]
Abstract
BACKGROUND The heme oxygenase (HO) system plays a significant role in neuroprotection and reduction of neuroinflammation and neurodegeneration. The system, via isoforms HO-1 and HO-2, regulates cellular redox balance. HO-1, an antioxidant defense enzyme, is highlighted due to its association with depression, characterized by heightened neuroinflammation and impaired oxidative stress responses. METHODOLOGY We observed the pathophysiology of HO-1 and phytochemicals as its modulator. We explored Science Direct, Scopus, and PubMed for a comprehensive literature review. Bibliometric and temporal trend analysis were done using VOSviewer. RESULTS Several phytochemicals can potentially alleviate neuroinflammation and oxidative stress-induced depressive symptoms. These effects result from inhibiting the MAPK and NK-κB pathways - both implicated in the overproduction of pro-inflammatory factors - and from the upregulation of HO-1 expression mediated by Nrf2. Bibliometric and temporal trend analysis further validates these associations. CONCLUSION In summary, our findings suggest that antidepressant agents can mitigate neuroinflammation and depressive disorder pathogenesis via the upregulation of HO-1 expression. These agents suppress pro-inflammatory mediators and depressive-like symptoms, demonstrating that HO-1 plays a significant role in the neuroinflammatory process and the development of depression.

Abstract
Coronavirus disease 2019 (COVID-19) is a recent pandemic caused by a novel severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) leading to pulmonary and extra-pulmonary manifestations due to the development of oxidative stress (OS) and hyperinflammation. The underlying cause for OS and hyperinflammation in COVID-19 may be related to the inhibition of nuclear factor erythroid 2-related factor 2 (Nrf2), a master regulator of antioxidative responses and cellular homeostasis. The Nrf2 pathway inhibits the expression of pro-inflammatory cytokines and the development of cytokine storm and OS in COVID-19. Nrf2 activators can attenuate endothelial dysfunction (ED), renin-angiotensin system (RAS) dysregulation, immune thrombosis, and coagulopathy. Hence, this review aimed to reveal the potential role of the Nrf2 pathway and its activators in the management of COVID-19. As well, we tried to revise the mechanistic role of the Nrf2 pathway in COVID-19.

Abstract
Liver fibrosis is a major challenge to global health because of its various complications, including cirrhosis and hepatocarcinoma, while no effective treatment is available for it. Sappanone A (SA) is a homoisoflavonoid extracted from the heartwood of Caesalpinia sappan Linn. with anti-inflammatory and antioxidant properties. However, the effects of SA on hepatic fibrosis remain unknown. This study aimed to investigate the protective effects of SA on carbon tetrachloride (CCl4)-induced liver fibrosis in mice. To establish a liver fibrosis model, mice were treated intraperitoneally (i.p.) with CCl4 for 4 weeks. SA (25, 50, and 100 mg/kg body weight) was i.p. injected every other day during the same period. Our data indicated that SA decreased liver injury, fibrotic responses, and inflammation due to CCl4 exposure. Consistently, SA reduced oxidative stress and its-mediated hepatocyte death in fibrotic livers. Of note, SA could not directly affect the activation of hepatic stellate cells. Mechanistically, SA treatment lessened oxidative stress-triggered cell death in hepatocytes after CCl4 exposure. SA down-regulated the expression of M1 macrophage polarization markers (CD86 and iNOS) and up-regulated the expression of M2 macrophage polarization markers (CD163, IL-10, and Arg1) in livers and macrophages. Meanwhile, SA induced the activation of peroxisome proliferator-activated receptor gamma (PPARγ). However, decreased inflammatory responses and the trend of M2 macrophage polarization provided by SA were substantially abolished by SR202 (a PPARγ inhibitor) treatment in macrophages. Additionally, SA treatment promoted fibrosis regression. Taken together, our findings revealed that treatment with SA alleviated CCl4-induced fibrotic liver in mice through suppression of oxidative stress-mediated hepatocyte death and promotion of M2 macrophage polarization via PPARγ. Thus, SA might pave the way for a new hepatoprotective agent to treat liver fibrosis.

Sappanone A: A natural PDE4 inhibitor with dual anti-inflammatory and antioxidant activities from the heartwood of Caesalpinia sappan L. JOURNAL OF ETHNOPHARMACOLOGY 2023; 304:116020. [PMID: 36529254 DOI: 10.1016/j.jep.2022.116020] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 11/28/2022] [Accepted: 12/02/2022] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sumu (Lignum sappan), the dry heartwood of Caesalpinia sappan L., is a traditional Chinese medicine used as an analgesic and anti-inflammatory agent. AIM OF THE STUDY The study aspired to discover natural phosphodiesterase 4 (PDE4) inhibitors with dual anti-inflammatory and antioxidant activities from Sumu for the treatment of chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS To accurately and efficiently identify natural PDE4 inhibitors from Sumu, molecular docking and molecular dynamics (MD) analysis methods were used for structure-based virtual screening of a self-built database of primary polyphenols in Sumu. According to the previous studies of Sumu and the free radical scavenging mechanism of polyphenols, the reported antioxidant components from Sumu and the potential antioxidants with the antioxidant pharmacophore of catechol and π-conjugated moieties were selected from the potential PDE4 inhibitors predicted by docking. Sappanone A, a potential PDE4 inhibitor with antioxidant activity from Sumu, was selected, calculated and synthesized to evaluate its dual anti-inflammatory and antioxidant functions in vitro and in vivo studies. Herein sappanone A was assayed for its inhibitory effects against PDE4 enzyme activity, tumor necrosis factor-alpha (TNF-α) production induced by lipopolysaccharide (LPS) in RAW264.7 macrophages and malondialdehyde (MDA) production induced by Fe2+ in mouse lung homogenate; sappanone A was also assayed for its abilities of radical (DPPH) scavenging, reducing Fe3+ and complexing Fe2+ in vitro. Additionally, LPS-induced acute lung injury (ALI) in mice was used to evaluate its anti-inflammatory activity as a PDE4 inhibitor in vivo, and the levels of TNF-α and total protein in bronchoalveolar lavage fluid (BALF) and myeloperoxidase (MPO) activity in the lung were assayed. RESULTS The present study predicted and validated that sappanone A was a promising PDE4 inhibitor from Sumu with dual anti-inflammation and antioxidant activities from Sumu. In vitro, sappanone A remarkably inhibited PDE4 enzyme activity and reduced TNF-α production induced by LPS in RAW264.7 macrophages and MDA production induced by Fe2+ in mouse lung homogenate. Meanwhile, it showed outstanding abilities of scavenging DPPH radicals, reducing Fe3+ and complexing Fe2+. In vivo, sappanone A (25 mg/kg and 50 mg/kg, i.p., twice daily for 7 days) distinctly prevented LPS-induced ALI in mice by reducing the levels of TNF-α and total protein in BALF and MPO activity in the lung. CONCLUSION Sappanone A is a natural PDE4 inhibitor with dual anti-inflammatory and antioxidant activities from the traditional Chinese medicine Sumu, which may be a promising therapeutic agent to prevent the vicious cycle of COPD inflammation and oxidative stress.

Abstract
Atherosclerosis (AS) is a common cardiovascular disease with complex pathogenesis, in which multiple pathways and their interweaving regulatory mechanism remain unclear. The primary transcription factor NF-κB plays a critical role in AS via modulating the expression of a series of inflammatory mediators under various stimuli such as cytokines, microbial antigens, and intracellular stresses. Endoplasmic reticulum (ER) stress, caused by the disrupted synthesis and secretion of protein, links inflammation, metabolic signals, and other cellular processes via the unfolded protein response (UPR). Both NF-κB and ER stress share the intersection regarding their molecular regulation and function and are regarded as critical individual contributors to AS. In this review, we summarize the multiple interactions between NF-κB and ER stress activation, including the UPR, NLRP3 inflammasome, and reactive oxygen species (ROS) generation, which have been ignored in the pathogenesis of AS. Given the multiple links between NF-κB and ER stress, we speculate that the integrated network contributes to the understanding of molecular mechanisms of AS. This review aims to provide an insight into these interactions and their underlying roles in the progression of AS, highlighting potential pharmacological targets against the atherosclerotic inflammatory process.

Abstract
Sappanone A (SA), a homoisoflavonoid compound extracted from the heartwood of Caesalpinia sappan Linn., exerts anti-inflammatory and antioxidant activities. However, the effects of SA on acetaminophen (APAP) overdose-induced acute liver injury (ALI) have not been determined yet. This study aims to explore the protective effects of SA and the potential mechanisms of action. Mice were pretreated with SA (25, 50, and 100 mg/kg) by intraperitoneal (i.p.) injection for seven days prior to APAP (300 mg/kg, i.p.) administration. At 12 h after APAP injection, serum and liver samples were collected. Primary murine hepatocytes were used to investigate the underlying mechanisms. SA pretreatment dose-dependently attenuated APAP-induced ALI, as validated by reduced serum alanine/aspartate aminotransferase levels, histopathologic lesions, and oxidative stress. Consistently, pretreatment with SA reduced the formation of APAP protein adducts in damaged livers of mice. Mechanistically, SA could facilitate the nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and thus promote cellular glutathione (GSH) synthesis. The hepatoprotective outcomes provided by SA were significantly abolished by treatment with ML385, a Nrf2 inhibitor. Besides, anti-inflammatory property of SA reduced inflammatory reaction in injured livers of mice. Of note, posttreatment with SA reveals significant therapeutic influences against APAP-induced ALI in mice. Collectively, our findings demonstrated that pretreated-SA ameliorated APAP-mediated ALI in mice, at least in part, by reducing the generation of APAP protein adducts via Nrf2-enhanced GSH synthesis, and by diminishing hepatic inflammation. Therefore, SA could be a potential hepatoprotective agent for treating ALI.

Abstract
Objective This study was to examine the anti-inflammatory effect of sappanone A on interleukin- (IL-) 1β-stimulated osteoarthritis (OA) chondrocytes. Methods Chondrocytes were pretreated with sappanone A for 2 h before subsequent IL-1β stimulation. The mRNA expression levels of iNOs, COX-2, aggrecan, and collagen-II were measured with qRT-PCR. The levels of TNF-α, IL-6, IL-8, MMP-3, and MMP-13 were determined by ELISA. The protein levels of iNOs, COX-2, ADAMTS-4, ADAMTS-5, aggrecan, collagen-II, p-p65, p65, IκBα, Nrf2, and HO-1 were assessed by Western blot. Results Sappanone A inhibited the IL-1β-stimulated production of NO, PGE2, iNOS, COX-2, TNF-α, IL-6, and IL-8 in OA chondrocytes. In addition, sappanone A suppressed the expression of MMP-3, MMP-13, ADAMTS-4, and ADAMTS-5 in IL-1β-stimulated OA chondrocytes. The degradation of ECM components was reversed by sappanone A. Sappanone A prevented NF-κB activation while enhanced Nrf2/HO-1 activation in IL-1β-treated chondrocytes. Conclusion Sappanone A may be a potent therapeutic agent for OA.

Abstract
Spinal cord injury (SCI) is a significant cause of disability, and treatment alternatives that generate beneficial outcomes and have no side effects are urgently needed. SCI may be treatable if intervention is initiated promptly. Therefore, several treatment proposals are currently being evaluated. Inflammation is part of a complex physiological response to injury or harmful stimuli induced by mechanical, chemical, or immunological agents. Neuroinflammation is one of the principal secondary changes following SCI and plays a crucial role in modulating the pathological progression of acute and chronic SCI. This review describes the main inflammatory events occurring after SCI and discusses recently proposed potential treatments and therapeutic agents that regulate inflammation after insult in animal models.

Abstract
Cancer is a complex and multistage disease that affects various intracellular pathways, leading to rapid cell proliferation, angiogenesis, cell motility, and migration, supported by antiapoptotic mechanisms. Chemoprevention is a new strategy to counteract cancer; to either prevent its incidence or suppress its progression. In this strategy, chemopreventive agents target molecules involved in multiple pathways of cancer initiation and progression. Nrf2, STAT3, and Src are promising molecular candidates that could be targeted for chemoprevention. Nrf2 is involved in the expression of antioxidant and phase II metabolizing enzymes, which have direct antiproliferative action as well as indirect activities of reducing oxidative stress and eliminating carcinogens. Similarly, its cross-talk with NF-κB has great anti-inflammatory potential, which can be utilized in inflammation-induced/associated cancers. STAT3, on the other hand, is involved in multiple pathways of cancer initiation and progression. Activation, phosphorylation, dimerization, and nuclear translocation are associated with tumor cell proliferation and angiogenesis. Src, being the first oncogene to be discovered, is important due to its convergence with many upstream stimuli, its cross-talk with other potential molecular targets, such as STAT3, and its ability to modify the cell cytoskeleton, making it important in cancer invasion and metastasis. Therefore, the development of natural/synthetic molecules and/or design of a regimen that can reduce oxidative stress and inflammation in the tumor microenvironment and stop multiple cellular targets in cancer to stop its initiation or retard its progression can form newer chemopreventive agents.

Sappanone a prevents diabetic kidney disease by inhibiting kidney inflammation and fibrosis via the NF-κB signaling pathway. Front Pharmacol 2022; 13:953004. [PMID: 36052141 PMCID: PMC9426375 DOI: 10.3389/fphar.2022.953004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Accepted: 07/01/2022] [Indexed: 11/30/2022] Open
Abstract
Background: Low grade of sterile inflammation plays detrimental roles in the progression of diabetic kidney disease (DKD). Sappanone A (SA), a kind of homoisoflavanone isolated from the heartwood of Caesalpinia sappan, exerts anti-inflammatory effects in acute kidney injury. However, whether SA has beneficial effects on diabetic kidney disease remains further exploration. Methods and Results: In the present study, uninephrectomized male mice were treated with Streptozotocin (STZ, 50 mg/kg) for five consecutive days to induce diabetes. Next, the diabetic mice were administered orally with SA (10, 20, or 30 mg/kg) or vehicle once per day. Our results showed that STZ treatment significantly enhanced damage in the kidney, as indicated by an increased ratio of kidney weight/body weight, elevated serum creatinine and blood urea nitrogen (BUN), as well as increased 24-h urinary protein excretion, whereas SA-treated mice exhibited a markedly amelioration in these kidney damages. Furthermore, SA attenuated the pathological changes, alleviated fibrotic molecules transforming growth factor-β1 (TGF-β1) and Collagen-IV (Col-IV) production, decreased inflammatory cytokines interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) expression in STZ-treated mice. Similarly, in glomerular mesangial cells, SA pretreatment decreased high glucose (HG)-induced proliferation, inflammatory cytokines excretion, and fibrotic molecules expression. Mechanistically, SA decreased the expression of nuclear factor kappa B (NF-κB) and restored the expression of total NF-κB inhibitor alpha (IκBα) both in vivo and in vitro. Conclusion: Our data suggest that SA may prevent diabetes-induced kidney inflammation and fibrosis by inhibiting the NF-κB pathway. Hence, SA can be potential and specific therapeutic value in DKD.

Abstract
Three new amide alkaloids, piperlongumamides D-F (14, 19, and 32); a new piperic ester, piperlongumester A (45); and two new natural compounds, methyl (2E,4Z)-5-(1,3-benzodioxol-5-yl)penta-2,4-dienoate (46) and trans-piperolein B ester (47), along with 41 known compounds were isolated from the fruits of Piper longum L. Their structures were identified by analyzing spectroscopic data, including mass spectrometry, 1D, and 2D NMR data. The anti-inflammatory and cytotoxic activities of all isolated compounds (1-47) were evaluated. Compounds 3, 6, and 19 inhibited nitric oxide production with IC50 values of 16.1 ± 0.94, 14.5 ± 0.57, and 27.3 ± 1.11 μM, respectively, whereas compound 1 exhibited strong cytotoxic activity toward three ovarian cancer cell lines A2780, TOV-112D, and SK-OV3, with IC50 values of 6.7 ± 0.77, 5.8 ± 0.29, and 48.3 ± 0.40 μM, respectively. Molecular docking simulations were performed to identify the interaction and binding mechanisms of these active metabolites with proteins related to inflammation and cancer.

Abstract
BACKGROUND Thai herbal formulations have been used traditionally in Thailand for the treatment of psoriasis. However, there is still a lack of scientific data supporting the effects of Thai herbal formulations in psoriasis treatment. OBJECTIVES This study aimed to demonstrate the therapeutic effects of Thai herbal formulations for the treatment of erythrodermic psoriasis. MATERIALS AND METHODS All Thai herbal formulations (haematic tonic, lymphatic treatment, skin treatment) were obtained from a traditional Thai medicine doctor, Mr. Somporn Chanwanitsakul. The effects of Thai herbal formulations in a patient with erythrodermic psoriasis were assessed for four weeks. Primary outcome, psoriasis area and severity index (PASI) and secondary outcome, safety data and dermatology life quality index (DLQI) measurements were evaluated at baseline and four weeks. Then, in vitro biological activities (antioxidant, anti-microbial, cytotoxic effects, and anti-inflammatory) of Thai herbal formulations were determined to promote the therapeutic effects. RESULTS Thai herbal formulations were safe and effective in the treatment of erythrodermic psoriasis and had a modest positive impact on the DQLI of the patient. In addition, in vitro studies have shown that all Thai herbal formulations revealed remarkable anti-oxidant and anti-inflammatory potential to support their therapeutic activities. However, the Thai herbal formulations possessed weak intrinsic antibacterial activities against all tested bacterial strains (MIC and MBC E. coli, S. aureus, S. pyogenes, P. aeruginosa: > 256 µg/ml). CONCLUSION The findings indicated that successful treatment of erythrodermic psoriasis with Thai herbal formulations was involved in their anti-oxidant and anti-inflammatory activities. They could be considered as an alternative treatment for refractory erythrodermic psoriasis.

Abstract
Cisplatin is a platinum-based chemotherapeutic that has long since been effective against a variety of solid-cancers, substantially improving the five-year survival rates for cancer patients. Its use has also historically been limited by its adverse drug reactions, or cisplatin-induced toxicities (CITs). Of these reactions, cisplatin-induced nephrotoxicity (CIN), cisplatin-induced peripheral neuropathy (CIPN), and cisplatin-induced ototoxicity (CIO) are the three most common of several CITs recognised thus far. While the anti-cancer activity of cisplatin is well understood, the mechanisms driving its toxicities have only begun to be defined. Most of the literature pertains to damage caused by oxidative stress that occurs downstream of cisplatin treatment, but recent evidence suggests that the instigator of CIT development is inflammation. Cisplatin has been shown to induce pro-inflammatory signalling in CIN, CIPN, and CIO, all of which are associated with persisting markers of inflammation, particularly from the innate immune system. This review covered the hallmarks of inflammation common and distinct between different CITs, the role of innate immune components in development of CITs, as well as current treatments targeting pro-inflammatory signalling pathways to conserve the use of cisplatin in chemotherapy and improve long-term health outcomes of cancer patients.

The Therapeutic Potential of Kaemferol and Other Naturally Occurring Polyphenols Might Be Modulated by Nrf2-ARE Signaling Pathway: Current Status and Future Direction. Molecules 2022; 27:molecules27134145.

Abstract
Kaempferol is a natural flavonoid, which has been widely investigated in the treatment of cancer, cardiovascular diseases, metabolic complications, and neurological disorders. Nrf2 (nuclear factor erythroid 2-related factor 2) is a transcription factor involved in mediating carcinogenesis and other ailments, playing an important role in regulating oxidative stress. The activation of Nrf2 results in the expression of proteins and cytoprotective enzymes, which provide cellular protection against reactive oxygen species. Phytochemicals, either alone or in combination, have been used to modulate Nrf2 in cancer and other ailments. Among them, kaempferol has been recently explored for its anti-cancer and other anti-disease therapeutic efficacy, targeting Nrf2 modulation. In combating cancer, diabetic complications, metabolic disorders, and neurological disorders, kaempferol has been shown to regulate Nrf2 and reduce redox homeostasis. In this context, this review article highlights the current status of the therapeutic potential of kaempferol by targeting Nrf2 modulation in cancer, diabetic complications, neurological disorders, and cardiovascular disorders. In addition, we provide future perspectives on kaempferol targeting Nrf2 modulation as a potential therapeutic approach.

Abstract
Bioassay-guided fractionation of Asarum heterotropoides var. mandshuricum F. Maekawa (Aristolochiaceae) root extract led to the isolation and characterization of one new ferulic acid glucose ester (1) and nine known lignans (2-10). Their structures were elucidated using extensive spectroscopic methods, including 1D and 2D NMR, and MS spectra. The anti-inflammatory effects of the isolated compounds were investigated via their inhibition against nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 mouse macrophage cells. Among them, compound 7 ((1R,2S,5R,6R)-5'-O-methylpluviatilol) showed the most effective inhibitory activity against NO production and expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) protein in an exceedingly dose-dependent manner. In addition, further study revealed that the mechanism of anti-inflammatory activity of the most active lignan (7) might be associated with the inhibition of extracellular-signal-regulated kinase (ERK) and nuclear factor kappa B (NF-κB) phosphorylation.

Abstract
Oxidative stress is the leading player in the onset and development of various diseases. The Keap1-Nrf2 pathway is a pivotal antioxidant system that preserves the cells' redox balance. It decreases inflammation in which the nuclear trans-localization of Nrf2 as a transcription factor promotes various antioxidant responses in cells. Through some other directions and regulatory proteins, this pathway plays a fundamental role in preventing several diseases and reducing their complications. Regulation of the Nrf2 pathway occurs on transcriptional and post-transcriptional levels, and these regulations play a significant role in its activity. There is a subtle correlation between the Nrf2 pathway and the pivotal signaling pathways, including PI3 kinase/AKT/mTOR, NF-κB and HIF-1 factors. This demonstrates its role in the development of various diseases. Curcumin is a yellow polyphenolic compound from Curcuma longa with multiple bioactivities, including antioxidant, anti-inflammatory, anti-tumor, and anti-viral activities. Since hyperglycemia and increased reactive oxygen species (ROS) are the leading causes of common diabetic complications, reducing the generation of ROS can be a fundamental approach to dealing with these complications. Curcumin can be considered a potential treatment option by creating an efficient therapeutic to counteract ROS and reduce its detrimental effects. This review discusses Nrf2 pathway regulation at different levels and its correlation with other important pathways and proteins in the cell involved in the progression of diabetic complications and targeting these pathways by curcumin.

Abstract
Aging is a process global in nature. The age of living organisms contributes to the appearance of chronic diseases, which not only reduce the quality of life, but also significantly damage it. Modern medicines can successfully fight multiple diseases and prolong life. At the same time, medications have a large number of side effects. New research indicates that bioactive phytochemicals have great potential for treating even the most severe diseases and can become an alternative to medicines. Despite many studies in this area, the effects of many plant ingredients on living organisms are poorly understood. Analysis of the mechanisms through which herbal preparations influence the aging process helps to select the right active substances, determine the optimal doses to obtain the maximum positive effect. It is preferable to check the effectiveness of plant extracts and biologically active components with geroprotective properties in vivo. For these purposes, live model systems such as Rattus rattus, Mus musculus, Drosophila melanogaster, and Caenorhabditis elegans are used. These models help to comprehensively study the impact of the developed new drugs on the aging process. The model organism C. elegans is gaining increasing popularity in these studies because of its many advantages. This review article discusses the advantages of the nematode C. elegans as a model organism for studying the processes associated with aging. The influence of various BAS and plant extracts on the increase in the life span of the nematode, on the increase in its stress resistance and on other markers of aging is also considered.

RNAseq analysis of treatment-dependent signaling changes during inflammation in a mouse cutaneous wound healing model. BMC Genomics 2021; 22:854. [PMID: 34823472 PMCID: PMC8614049 DOI: 10.1186/s12864-021-08083-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Accepted: 10/08/2021] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Despite proven therapeutic effects in inflammatory conditions, the specific mechanisms of phytochemical therapies are not well understood. The transcriptome effects of Traumeel (Tr14), a multicomponent natural product, and diclofenac, a non-selective cyclooxygenase (COX) inhibitor, were compared in a mouse cutaneous wound healing model to identify both known and novel pathways for the anti-inflammatory effect of plant-derived natural products. METHODS Skin samples from abraded mice were analyzed by single-molecule, amplification-free RNAseq transcript profiling at 7 points between 12 and 192 h after injury. Immediately after injury, the wounds were treated with either diclofenac, Tr14, or placebo control (n = 7 per group/time). RNAseq levels were compared between treatment and control at each time point using a systems biology approach. RESULTS At early time points (12-36 h), both control and Tr14-treated wounds showed marked increase in the inducible COX2 enzyme mRNA, while diclofenac-treated wounds did not. Tr14, in contrast, modulated lipoxygenase transcripts, especially ALOX12/15, and phospholipases involved in arachidonate metabolism. Notably, Tr14 modulated a group of cell-type specific markers, including the T cell receptor, that could be explained by an overarching effect on the type of cells that were recruited into the wound tissue. CONCLUSIONS Tr14 and diclofenac had very different effects on the COX/LOX synthetic pathway after cutaneous wounding. Tr14 allowed normal autoinduction of COX2 mRNA, but suppressed mRNA levels for key enzymes in the leukotriene synthetic pathway. Tr14 appeared to have a broad 'phytocellular' effect on the wound transcriptome by altering the balance of cell types present in the wound.

Abstract
CONTEXT Portulaca oleracea L. is herbaceous succulent annual plant, which belongs to the Portulacaceae family. Many studies have shown its wide spectrum of pharmacological activities such as anti-cancer and anti-diabetic effects. OBJECTIVES The objective of this study was to identify the anti-inflammatory effects of HM-chromanone isolated from Portulaca oleracea L. in LPS-stimulated RAW 264.7 macrophages. MATERIALS AND METHODS LPS (1 μg/ml)-stimulated mouse RAW 264.7 macrophages were used to assess the anti-inflammatory effect of HM-chromanone (10-50 μM). Cell viability was evaluated by MTT assay. In addition, the production of intracellular ROS, superoxide anion, lipid peroxide, NO, and PGE2, and activity of antioxidant enzymes were analyzed. The expressions of iNOS, COX-2, IκB, NF-κB, TNF-α, IL-1β and IL-6 were evaluated by western blot analysis. RESULTS HM-chromanone has demonstrated that there is no significant cytotoxic effect on the viability of RAW 264.7 macrophages. In LPS-stimulated RAW 264.7 cells, HM-chromanone treatment was found to significantly inhibit the production of intracellular ROS, superoxide anion and lipid peroxide, while enhancing the activity of antioxidant enzymes such as SOD, catalase, and GSH-px. Additionally, HM-chromanone treatment was observed to inhibit NO and PGE2 production by inhibiting the expression of iNOS and COX-2. Subsequently, HM-chromanone was observed to significantly suppress LPS-induced expression of IκB, NF-κB, TNF-α, IL-1β and IL-6. DISCUSSION AND CONCLUSION Overall, our results suggested that HM-chromanone suppresses LPS-induced inflammation in RAW 264.7 macrophages by downregulating the expression of inflammatory factors.

Modulation of Nrf2 and NF-κB Signaling Pathways by Naturally Occurring Compounds in Relation to Cancer Prevention and Therapy. Are Combinations Better Than Single Compounds? Int J Mol Sci 2021; 22:ijms22158223. [PMID: 34360990 PMCID: PMC8348704 DOI: 10.3390/ijms22158223] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 07/24/2021] [Accepted: 07/26/2021] [Indexed: 12/14/2022] Open
Abstract
Nrf2 (nuclear factor erythroid 2-related factor 2) and NF-κB (nuclear factor–kappa B) signaling pathways play a central role in suppressing or inducing inflammation and angiogenesis processes. Therefore, they are involved in many steps of carcinogenesis through cooperation with multiple signaling molecules and pathways. Targeting both transcription factors simultaneously may be considered an equally important strategy for cancer chemoprevention and therapy. Several hundreds of phytochemicals, mainly edible plant and vegetable components, were shown to activate Nrf2 and mediate antioxidant response. A similar number of phytochemicals was revealed to affect NF-κB. While activation of Nrf2 and inhibition of NF-κB may protect normal cells against cancer initiation and promotion, enhanced expression and activation in cancer cells may lead to resistance to conventional chemo- or radiotherapy. Most phytochemicals, through different mechanisms, activate Nrf2, but others, such as luteolin, can act as inhibitors of both Nrf2 and NF-κB. Despite many experimental data confirming the above mechanisms currently, limited evidence exists demonstrating such activity in humans. Combinations of phytochemicals resembling that in a natural food matrix but allowing higher concentrations may improve their modulating effect on Nrf2 and NF-κB and ultimately cancer prevention and therapy. This review presents the current knowledge on the effect of selected phytochemicals and their combinations on Nrf2 and NF-κB activities in the above context.

Abstract
Nuclear factor erythroid 2-related factor 2 (Nrf2) is an important transcription factor that reduces oxidative stress. When reactive oxygen species (ROS) or reactive nitrogen species (RNS) are detected, Nrf2 translocates from the cytoplasm into the nucleus and binds to the antioxidant response element (ARE), which regulates the expression of antioxidant and anti-inflammatory genes. Nrf2 impairments are observed in the majority of neurodegenerative disorders, including Alzheimer’s disease (AD). The classic hallmarks of AD include β-amyloid (Aβ) plaques, and neurofibrillary tangles (NFTs). Oxidative stress is observed early in AD and is a novel therapeutic target for the treatment of AD. The nuclear translocation of Nrf2 is impaired in AD compared to controls. Increased oxidative stress is associated with impaired memory and synaptic plasticity. The administration of Nrf2 activators reverses memory and synaptic plasticity impairments in rodent models of AD. Therefore, Nrf2 activators are a potential novel therapeutic for neurodegenerative disorders including AD.

Abstract
Accumulating evidence reveals that ROS is one of the key mediators that contribute to the development of asthma. Studies on antioxidants have shown to have beneficial effects on asthma management. However, we still do not know the precise mechanism, and the effects depend on age. This study was conducted to assess the levels of ROS and the effect of antioxidants in younger and older mice using an eosinophilic asthma model. We analyzed airway hyperresponsiveness (AHR), cytokines in bronchoalveolar lavage fluid (BALF), inflammatory cell counts, and the expression levels of NFκB, Nrf2, EPx, and EDN in the lung tissue, as well as the level of ROS in the lung tissue and BALF. The degree of eosinophilia and the levels of IL-5, ROS, and NFκB were significantly increased, whereas the endogenous levels of vitamin E and Nrf2 were decreased in the lung and BALF in the older mice compared to younger mice. The administration of vitamin E attenuated AHR, airway inflammation, and the level of IL-13 and ROS and enhanced the Nrf2 level in the older mice compared to the younger mice. Taken together, vitamin E treatment may have the therapeutic potential through restoration of the Nrf2 level, especially in elderly asthma.

Abstract
Myocardial ischemia reperfusion injury (MIRI) is a complex pathophysiological process involved with the activation of oxidative stress, inflammation and apoptosis. Sappanone A (SA), a homoisoflavanone isolated from the heartwood of Caesalpinia sappan L., could exhibit antioxidant, anti-inflammatory and anti-apoptotic activities. Therefore, we assumed that SA has a potential use for preventing against MIRI. The present study aimed to investigate the effect of SA treatment on MIRI and its mechanism. Cardiomyocytes (H9c2 cells) were treated with SA for 1 h, followed by 6 h of hypoxia/3 h of reoxygenation. Cell viability assay was detected by CCK-8 assay. Apoptosis was measured by flow cytometry and Hoechst staining. Mitochondrial permeability transition pore (mPTP) opening and mitochondrial transmembrane potential (ΔΨm) were measured by spectrophotometry and JC-1 staining. The changes of mitochondrial apoptosis-related proteins and PI3K–Akt–Gsk-3β signaling pathway were evaluated by Western blotting. The results showed that SA pretreatment enhanced the cell viability and decreased the activity of myocardial enzyme in a dose-dependent manner. Moreover, SA pretreatment significantly inhibited apoptosis, blocked mPTP opening, suppressed the release of ΔΨm, prevented the cytochrome c releasing from mitochondria into cytoplasm, and repressed the cleavage of caspase-9 and caspase-3. Furthermore, SA pretreatment increased the phosphorylation levels of Akt and Gsk-3β but not of Stat-3. Meanwhile, the protective effect of SA was abrogated by PI3K inhibitor (LY294002). In conclusion, our results demonstrate that SA could prevent hypoxia/reoxygenation-induced cardiomyocytes injury through inhibition of mitochondrial apoptosis and activation of PI3K–Akt–Gsk-3β pathway. Thus, SA may have a potential use for the prevention of MIRI.

Role of microgliosis, oxidative stress and associated neuroinflammation in the pathogenesis of Parkinson's disease: The therapeutic role of Nrf2 activators. Neurochem Int 2021; 145:105014.

Abstract
Microglial cells are the resident immune cells of the central nervous system. They are essential for normal functioning, maintenance of tissue integrity, clearance of dying neurons, elimination of pathogens, development and maintenance of homeostasis of the CNS. Many studies have consistently reported that oxidative stress and associated neuroinflammation mediated by microglial cells have a degenerating effect on dopaminergic neurons. In Parkinson's disease, the microglial cells by a process called microgliosis undergo rapid proliferation, accumulate at the site of tissue injury and undergo phenotypic and functional changes that result in the release of massive amounts of free radicals causing inflammation and neurodegeneration of dopaminergic neurons. Following the discovery of the irrefutable role oxidative stress and associated neuroinflammation, several proven antioxidants were tested for possible protective and therapeutic potential in Parkinson's disease but the results so far have not been encouraging and equivocal. Consequently, it is rational to look for endogenous targets that enhance the oxidative defense mechanism against free radicals and protect dopaminergic neurons from neuroinflammation and neurodegeneration. One such target is a nuclear factor-erythroid -2-related factor 2 (Nrf2). Nrf2 is a redox-sensitive transcription factor located in the cytoplasm of the cells that helps cells adapt to oxidative stress and inflammation by upregulating the expression of almost 200 cytoprotective genes. Fractalkine exists in a transmembrane form and a soluble form and is a cytokine that links microglial cells and Nrf2. The fractalkine receptors, expressed exclusively by microglial cells, on activation by fractalkine protects dopaminergic neurons from degeneration caused by free radicals and pro-inflammatory mediators through increased expression of Nrf2 dependent genes. The current anti Parkinsonism drugs do not cure the disease and also cause several debilitating motor and non-motor adverse drug effects. So it becomes imperative to explore novel targets and discover novel therapeutic agents to treat Parkinson's disease in a better way and improve the quality of life of patients with Parkinson's disease.

Abstract
Endoplasmic reticulum stress is an important contributor to the cerebral ischemic injury. Sappanone A (SA), a kind of natural homoisoflavanone extracted from Caesalpinia sappan L, has been evidenced to exhibit anti-inflammatory and antioxidative properties. The present study aimed to investigate the potential neuroprotective effects of SA in cerebral ischemia-reperfusion injury. The potential neuroprotective effect of SA was tested in a rat model of middle cerebral artery occlusion (MCAO) allowing reperfusion and PC12 cell model of oxygen-glucose deprivation and reperfusion (OGD/R). Post-ischemic neuronal injury was evaluated by 2, 3, 5-triphenyltetrazolium chloride (TTC) and hematoxylin-eosin (H&E) staining. The levels of inflammatory factors and oxidative stress-related markers were detected using corresponding kits. Cell apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) or flow cytometry, and the expression of apoptosis-associated proteins was determined using western blot analysis. Subsequently, endoplasmic reticulum stress-related proteins were detected through western blot analysis, and CCAAT/enhancer binding protein (C/EBP) homologous protein (CHOP) was overexpressed to confirm the contribution of endoplasmic reticulum stress inhibition by SA to the neuroprotective effects post OGD/R. Results revealed that SA was effective in ameliorating cerebral infarction and pathological injuries post-reperfusion following MCAO, which is associated with reduced inflammation, oxidative stress, and cell apoptosis by SA in the brain. Consistently, these neuroprotective effects of SA post ischemia-reperfusion were also observed in a PC12 cell model of OGD/R. Importantly, endoplasmic reticulum stressors, including the CHOP, the 78 kDa glucose-regulated protein 78 (GRP78), and phosphorylated eukaryotic initiation factors 2α (EIF-2α), were significantly downregulated by SA, while CHOP overexpression attenuated the beneficial effects of SA on inflammation, oxidative stress, and apoptosis in OGD/R-induced PC12 cells. These results demonstrated that SA alleviates endoplasmic reticulum stress, ameliorating inflammation, oxidative stress, and apoptosis, and thereby serves as therapeutic potential for protection against cerebral ischemia-reperfusion injury in ischemic stroke.

Abstract
Recently, there is an increasing interest in searching for harmless natural products isolated from plant materials that can be used as beneficial dietary supplements and/or therapeutic drug candidates. The present study aimed to test the potential protective role of Pulicaria petiolaris (PP, Asteraceae) against hepatic and cardiotoxic effects associated with lipopolysaccharide (LPS) injection. PP was given orally for 5 days at two different doses before LPS injection. Results have shown that LPS induced remarkable hepatic and cardiac injurious effects in mice. Hepatic damage was evident through increased serum transaminases, lactate dehydrogenase (LDH), alkaline phosphatase (ALP), and activity. Estimation of high levels of serum creatine kinase-MB (CK-MB) and cardiac troponin I indicated cardiac damage. Histopathological examination of liver and heart confirmed the biochemical results. Increase in oxidative stress along with a depressed antioxidant status of liver and heart were observed in LPS-intoxicated animals. Furthermore, LPS induced activation of nuclear factor-κB (NF-κB) and subsequent elevation of inflammatory cytokines (TNF-α, IL-6). On the other hand, PP treatment successfully safeguards both organs against LPS-induced injury as indicated by the improvement of the biochemical and histopathological parameters. These results suggest that PP ameliorates LPS-induced hepatic and cardiac oxidative injurious effects via antioxidant and anti-inflammatory effects.

Abstract
The incidence of myocardial infarction, among the causes of cardiovascular morbidity and mortality, is increasing globally. In this study, left ventricular (LV) dysfunction, including LV systolic and diastolic function, was investigated in a rat myocardial ischemia/reperfusion injury model with echocardiography. The homoisoflavanone sappanone A is known for its anti-inflammatory effects. Using echocardiography, we found that sappanone A administration significantly improved LV systolic and diastolic function in a rat myocardial ischemia/reperfusion injury model, especially in the early phase development of myocardial infarction. Based on myocardial infarct size, serum cardiac marker assay, and histopathological evaluation, sappanone A showed higher efficacy at the doses used in our experiments than curcumin and was evaluated for its potential to improve LV function.

Abstract
Sappanone A (SA) is a homoisoflavonoid compound isolated from Caesalpinia sappan L. that selectively binds to inosine monophosphate dehydrogenase 2, a protein involved in aging. It is unknown if SA has an anti-aging effect and what is it mechanism. This study aimed to investigate the lifespan-extending and health-enhancing effects of SA, and the potential pharmacological mechanism in Caenorhabditis elegans (C. elegans). The worms were exposed to 0-50 μM SA. The effect on the lifespan was observed, and health status was evaluated by detecting motility, feeding, reproduction, thermotolerance, lipofuscin and ROS accumulation. To explore a possible mechanism, the transcription of the genes of the insulin/insulin-like growth factor-1 signalling pathway and heat stress response was detected by RT-qPCR. Moreover, subcellular distribution of green fluorescent protein-labeled DAF-16 was determined, and the interaction between SA and HSP-90 protein was simulated by molecular docking. We found that SA prolonged lifespan in C. elegans and enhanced motility and thermotolerance. The feeding and reproduction were not impacted. The ROS and lipofuscin accumulation was declined. Mechanistic study revealed that the gene expression levels of daf-16 and hsp-90 were up-regulated. Moreover, DAF-16 was translocated into the nucleus. SA was docked into the active pocket of HSP-90 in the simulation. SA (50 μM) can extend lifespan in C. elegans and decelerate aging by regulating the IIS pathway, and daf-16 is specifically important for the regulation of longevity. HSP-90 was involved in the enhancement of thermotolerance. Thus, SA may act as a promising candidate for the development of an anti-aging agent.

Shi X, Tao G, Ji L, Tian G. Sappanone A Protects Against Myocardial Ischemia Reperfusion Injury by Modulation of Nrf2. DRUG DESIGN DEVELOPMENT AND THERAPY 2020; 14:61-71. [PMID: 32021092 PMCID: PMC6955610 DOI: 10.2147/dddt.s230358] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Accepted: 12/05/2019] [Indexed: 12/27/2022]
Abstract
Background Oxidative stress is a major contributor to the onset and development of myocardial ischemia reperfusion injury (MIRI). Sappanone A (SA), a homoisoflavanone extracted from the heartwood of Caesalpinia sappan L., has been demonstrated to possess powerful antioxidant activity. Therefore, this study aimed to determine the protective effect of SA on MIRI and investigate its underlying mechanism. Methods The rat hearts were isolated and underwent 30-min ischemia, followed by 120-min reperfusion to establish the MIRI model, using the Langendorff method. SA was administrated intraperitoneally into rats 1 h prior to heart isolation. The myocardial infarct size and apoptosis were measured by TTC and terminal deoxynucleotidyl transferase dUTP nick end labeling staining. Myocardial enzyme activity, MDA content and the activities of SOD and GSH-Px were detected by colorimetric spectrophotometric method. Reactive oxygen species (ROS) level was detected by DCFH-DA probe. The change in Keap1/Nrf2 signaling pathway was evaluated by Western blotting. Results SA reduced myocardial infarct size and the release of CK-MB and LDH in a dose-dependent manner. Moreover, SA improved the recovery of cardiac function, inhibited MIRI-induced apoptosis, repressed the production of ROS and MDA, and enhanced the activities of SOD and GSH-Px. Mechanistically, SA downregulated Keap1, induced Nrf2 nuclear accumulation, and enhanced Nrf2 transcriptional activity, subsequently resulting in an increase in the expression of the Nrf2 target genes heme oxygenase-1 and NAD(P)H quinone dehydrogenase 1. Moreover, SA enhanced the phosphorylation of Nfr2, but the enhancement in Nfr2 phosphorylation was abrogated by PKC or PI3K inhibitor. Conclusion Collectively, it was demonstrated that SA prevents MIRI via coordinating the cellular antioxidant defenses and maintaining the redox balance, by modulation of Nrf2 via the PKC or PI3K pathway. Therefore, SA was a potential therapeutic drug for treating MIRI.

Abstract
This review documents all the new homoisoflavonoids (HIFs) that have been reported since 2007, whose total number has grown from 159 in 2007 to 295 at the present time. This review contains their structures, biological sources, plant parts they are obtained from, and, if reported, their optical rotations and melting points. The same classification is followed as an earlier review to ease reference to both reviews. This review takes note of the recent revision of plant families that were known to contain HIFs that have now been merged into one big family, Asparagaceae. Homoisoflavonoids also occur in Fabaceae and others. Two taxa, Ophiopogoan japonicus (Asparagaceae) and Caesalpinia sappan (Fabaceae), have been the source of many HIFs. These are briefly summarized. The biological properties of HIFs are also reviewed under the topics such as antioxidant, anti-inflammatory, antimicrobial, antidiabetic, and cytotoxic. The review also surveys the total synthesis of natural HIFs. All new compounds are classified and tabulated following the same style as the previous review. Dedicated to Professor Andrew Paul Krapcho on the occasion of his 87th Birthday.

Abstract
Ginkgo biloba L., well known as living fossil, have various pharmacological activities. Eighteen compounds were isolated from Ginkgo male flowers including a novel matsutake alcohol glycoside, Ginkgoside A (1), and 17 known compounds-calaliukiuenoside (2), benzylalcohol O-α-l-arabinopyranosyl-(1 → 6)-β-d-glucopyranoside (3), amentoflavone (4), sciadopitysin (5), bilobetin (6), isoginkgetin (7), olivil 4-O-β-d-glucopyranoside (8), dihydrodehydrodiconiferyl alcohol-4-O-β-d-glucoside (9), (+)-cyclo-olivil-6-O-β-d-glucopyranoside (10), (-)-isolariciresinol 4-O-β-d-glucopyranoside (11), coniferin (12), trans-cinnamic acid-4-O-β-d-glucopyranoside (13), p-coumaryl alchol glucoside (14), stroside B (15), methylconiferin (16), cis-p-coumaric acid 4-O-β-d-glucopyranoside (17), and cis-coniferin (18). Thirteen of these compounds had not previously found in Ginkgo. All extractive fractions and isolated compounds were evaluated for their anti-inflammatory ability in the lipopolysaccharide-induced RAW264.7 macrophages. The ethanol extract of Ginkgo flowers and the chloroform and ethyl acetate fractions can significantly decrease nitric oxide (NO), interleukin-6 (IL-6), and prostaglandin E2 (PGE2 ) production at 100 μg/ml. The most effective compounds, bilobetin (6) and isoginkgetin (7), elevated the NO inhibition ratios to 80.19% and 82.37% at 50 μM, respectively. They also exhibited significant dose-dependent inhibitory effects on tumor necrosis factor-α, IL-6, PGE2 , inducible NO synthase mRNA, and cyclooxygenase-2 mRNA levels. So they can be promising candidates for the development of new anti-inflammatory agents.

Sappanone A prevents hypoxia-induced injury in PC-12 cells by down-regulation of miR-15a. Int J Biol Macromol 2018; 123:35-41. [PMID: 30395900 DOI: 10.1016/j.ijbiomac.2018.11.002] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Revised: 09/27/2018] [Accepted: 11/01/2018] [Indexed: 11/20/2022]
Abstract
OBJECTIVE We aimed to explore the effect of Sappanone A on neurologic damage induced by hypoxia. METHODS PC-12 cells were pre-treated with Sappanone A and were simulated by hypoxia. miRNA transfection was performed to overexpress or suppress the expression of miR-15a in PC-12 cells. Cell viability, apoptosis, migration, and expression levels of miR-15a were tested to evaluate the in vitro impact of Sappanone A on hypoxia-injured PC-12 cells. RESULTS Hypoxia exposure induced a significant damage in PC-12 cells, as evidenced by the repressed cell growth, the induced apoptosis and the impaired migrating capacity. Sappanone A pretreatment protected PC-12 cells against hypoxia-mediated cell damage. More interestingly, Sappanone A treatment down-regulated miR-15a, and the neuroprotective effects of Sappanone A were attenuated by miR-15a overexpression while were accelerated by miR-15a suppression. Finally, Sappanone A significantly activated Wnt/β-catenin and PI3K/AKT signaling pathways. And the activation of these two signaling induced by Sappanone A were repressed by miR-15a overexpression and were enhanced by miR-15a suppression. CONCLUSION Sappanone A exerted protective activity in PC-12 cells which were stimulated by hypoxia. One of the possible mechanisms of the neuroprotective effect is that: Sappanone A down-regulated the expression of miR-15a, and thus activated Wnt/β-catenin and PI3K/AKT signaling pathways.

Abstract
The inflammatory response of sepsis induced by lipopolysaccharide (LPS) may result in irreversible cardiac dysfunction. Glutamine (GLN) has a multitude of pharmacological effects, including anti-inflammatory abilities. Previous studies have reported that GLN attenuated LPS-induced acute lung injury and intestinal mucosal injury. The present study investigated whether GLN exerts potential protective effects on LPS-induced cardiac dysfunction. Male Sprague-Dawley rats were divided into three groups (15 rats per group), including the control (saline-treated), LPS and LPS+GLN groups. Pretreatment with 1 g/kg GLN was provided via gavage for 5 days in the LPS+GLN group, while the control and LPS groups received the same volume of normal saline. On day 6, a cardiac dysfunction model was induced by administration of LPS (10 mg/kg). After 24 h, the cardiac functions of the rats that survived were detected by echocardiography and catheter-based measurements. The serum levels of tumor necrosis factor α (TNF-α), interleukin (IL)-1β and IL-6 were detected by enzyme-linked immunosorbent assay, while the mRNA levels of toll-like receptor (TLR)4, TNF-α, IL-1β and IL-6 were examined by reverse transcription-quantitative polymerase chain reaction. The protein expression of TLR4, mitogen-activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) were also determined by western blot analysis. The results of echocardiography and catheter-based measurements revealed that GLN treatment attenuated cardiac dysfunction. GLN treatment also attenuated the serum and mRNA levels of the pro-inflammatory cytokines. In addition, the protein levels of TLR4, phosphorylated (p-)extracellular signal-regulated kinase, p-c-Jun N-terminal kinase and p-P38 were reduced upon GLN pretreatment. Furthermore, GLN pretreatment resulted in decreased activation of the NF-κB signaling pathway. In conclusion, GLN has a potential therapeutic effect in the protection against cardiac dysfunction mediated by sepsis through regulating the TLR4/MAPK/NF-κB signaling pathway.

Abstract
Inosine monophosphate dehydrogenase (IMPDH) of human is an attractive target for immunosuppressive agents. Currently, small-molecule inhibitors do not show good selectivity for different IMPDH isoforms (IMPDH1 and IMPDH2), resulting in some adverse effects, which limit their use. Herein, we used a small-molecule probe specifically targeting IMPDH2 and identified Cysteine residue 140 (Cys140) as a selective druggable site. On covalently binding to Cys140, the probe exerts an allosteric regulation to block the catalytic pocket of IMPDH2 and further induces IMPDH2 inactivation, leading to an effective suppression of neuroinflammatory responses. However, the probe does not covalently bind to IMPDH1. Taken together, our study shows Cys140 as a druggable site for selectively inhibiting IMPDH2, which provides great potential for development of therapy agents for autoimmune and neuroinflammatory diseases with less unfavorable tolerability profile.

Abstract
A series of homoisoflavonoid derivatives was designed, synthesized and evaluated as potential multi-functional anti-Alzheimer's agents for their inhibitory activity on cholinesterase and monoamine oxidase. Among them, compound 16 showed moderate acetylcholinesterase (AChE) inhibitory activity (eeAChE IC50 = 0.89 ± 0.02 μM; hAChE IC50 = 0.657 ± 0.002 μM) and significant monoamine oxidase B (MAO-B) inhibitory activity (hMAO-B IC50 = 0.0372 ± 0.0002 μM). Kinetic analysis of AChE, MAO-B inhibition and molecular modeling studies revealed that compound 16 is a dual binding site inhibitor of AChE and noncompetitive inhibitor of MAO-B. Furthermore, 16 could penetrate through the blood-brain barrier (BBB) in vitro. Most importantly, oral administration of 16 demonstrated no marked signs of acute toxicity and it could significantly reverse scopolamine-induced memory impairment in mice. These results suggested that compound 16 is a promising multifunctional drug candidate with potential effect for the treatment of Alzheimer's disease.

Phytother Res 2017; 31:663-670. [PMID: 28185326 DOI: 10.1002/ptr.5780] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2016] [Revised: 01/12/2017] [Accepted: 01/12/2017] [Indexed: 01/27/2023]
Abstract
In the present study, ten alkaloids, namely chabamide (1), pellitorine (2), retrofractamide A (3), pyrroperine (4), isopiperolein B (5), piperamide C9:1 (8E) (6), 6,7-dehydrobrachyamide B (7), 4,5-dihydropiperine (8), dehydropipernonaline (9), and piperine (10), were isolated from the fruits of Piper nigrum. Among these, chabamide (1), pellitorine (2), retrofractamide A (3), isopiperolein B (5), and 6,7-dehydrobrachyamide B (7) exhibited significant inhibitory activity on lipopolysaccharide-induced nitric oxide (NO) production in RAW264.7 cells, with IC50 values of 6.8, 14.5, 30.2, 23.7, and 38.5 μM, respectively. Furthermore, compound 1 inhibited lipopolysaccharide-induced NO production in bone marrow-derived macrophages with IC50 value of 9.5 μM. Consistent with NO inhibition, treatment of RAW264.7 cells with chabamide (1), pellitorine (2), and 6,7-dehydrobrachyamide B (7) suppressed expression of inducible NO synthase and cyclooxygenase-2. Chabamide (1), pellitorine (2), and 6,7-dehydrobrachyamide B (7) induced heme-oxygenase-1 expression at the transcriptional level. In addition, compound 1 induced the nuclear translocation of nuclear factor-E2-related factor 2 (Nrf2) and upregulated the expression of Nrf2 target genes, NAD(P)H:quinone oxidoreductase 1 and γ-glutamyl cysteine synthetase catalytic subunit, in a concentration-dependent manner in RAW264.7 cells. These findings suggest that chabamide (1) from P. nigrum exert antiinflammatory effects via the activation of the Nrf2/heme-oxygenase-1 pathway; hence, it might be a promising candidate for the treatment of inflammatory diseases.

Abstract
Inflammation is the most common feature of many chronic diseases and complications, while playing critical roles in carcinogenesis. Several studies have demonstrated that Nrf2 contributes to the anti-inflammatory process by orchestrating the recruitment of inflammatory cells and regulating gene expression through the antioxidant response element (ARE). The Keap1 (Kelch-like ECH-associated protein)/Nrf2 (NF-E2 p45-related factor 2)/ARE signaling pathway mainly regulates anti-inflammatory gene expression and inhibits the progression of inflammation. Therefore, the identification of new Nrf2-dependent anti-inflammatory phytochemicals has become a key point in drug discovery. In this review, we discuss the members of the Keap1/Nrf2/ARE signal pathway and its downstream genes, the effects of this pathway on animal models of inflammatory diseases, and crosstalk with the NF-κB pathway. In addition we also discuss about the regulation of NLRP3 inflammasome by Nrf2. Besides this, we summarize the current scenario of the development of anti-inflammatory phytochemicals and others that mediate the Nrf2/ARE signaling pathway.

3H-1,2-dithiole-3-thione as a novel therapeutic agent for the treatment of experimental autoimmune encephalomyelitis. Brain Behav Immun 2016; 57:173-186.

Abstract
3H-1,2-dithiole-3-thione (D3T), the simplest member of the sulfur-containing dithiolethiones, is found in cruciferous vegetables, and has been previously reported to be a potent inducer of antioxidant genes and glutathione biosynthesis by activation of the transcription factor Nrf2. D3T is a cancer chemopreventive agent and possesses anti-inflammatory properties. Although D3T has been shown to protect against neoplasia, the effect of D3T in the autoimmune inflammatory disease multiple sclerosis/experimental autoimmune encephalomyelitis (EAE) is unknown. The present study is the first report of the therapeutic effect of D3T in EAE. Our results show D3T, administered post immunization, not only delays disease onset but also dramatically reduces disease severity in EAE. Strikingly, D3T, administered post disease onset of EAE, effectively prevents disease progression and exacerbation. Mechanistic studies revealed that D3T suppresses dendritic cell activation and cytokine production, inhibits pathogenic Th1 and Th17 differentiation, represses microglia activation and inflammatory cytokine expression, and promotes microglia phase II enzyme induction. In summary, these results indicate that D3T affects both innate and adaptive immune cells, and the protective effect of D3T in EAE might be attributed to its effects on modulating dendritic cell and microglia activation and pathogenic Th1/Th17 cell differentiation.

Abstract
BACKGROUND Sappanone A (SA) is isolated from the heartwood of Caesalpinia sappan and exerts a wide range of pharmacological activities. In the present study, we investigated the protective effects of SA on allergic asthma in a murine model of ovalbumin (OVA)-induced asthma. METHODS BALB/c mice were sensitized and challenged. Then, the mice were intraperitoneally injected with SA (12.5, 25 and 50 mg/kg) 1 h before OVA challenge; 24 h after the last challenge, the mice were sacrificed, and data were collected by different experimental methods. RESULTS The results showed that SA dose-dependently reduced inflammatory cell counts, levels of cytokines IL-4, IL-5 and IL-13, and OVA-specific IgE in bronchoalveolar lavage fluid. The level of IFN-γ decreased by OVA was upregulated by the treatment with SA. Furthermore, SA was found to attenuate the airway inflammation and mucus hypersecretion induced by the OVA challenge. In addition, SA dose-dependently upregulated the expression of Nrf2 and HO-1. SA inhibited OVA-induced asthma by activating the Nrf2 signaling pathway. CONCLUSIONS These data suggest that SA may have a potential use as a therapeutic agent for asthma.

Abstract
Cisplatin (CP) is an anti-cancer drug that often causes nephrotoxicity due to enhanced inflammatory response and oxidative stress. Sappanone A (SA), a homoisoflavanone isolated from the heartwood of Caesalpinia sappan, has been known to have antioxidant and anti-inflammatory effects. In this study, we aimed to investigate the protective effects and mechanism of SA on CP-induced kidney injury in mice. The results showed that treatment of SA improved CP-induced histopathalogical injury and renal dysfunction. SA also inhibited CP-induced MPO, MDA, TNF-α and IL-1β production and up-regulated the activities of SOD and GSH-PX decreased by CP. SA significantly inhibited the apoptosis rate of kidney tissues induced by CP. Furthermore, SA was found to inhibit CP-induced NF-κB activation. Treatment of SA up-regulated the expression of Nrf2 and HO-1 in a dose-dependent manner. In vitro, SA dose-dependently inhibited CP-induced TNF-α and IL-1β production and NF-κB activation in HK-2 cells. In conclusion, these results suggested that SA inhibited CP-induced kidney injury through activating Nrf2 and inhibiting NF-κB activation. SA was a potential therapeutic drug for treating CP-induced kidney injury.

Abstract
AIMS The present study investigated the therapeutic efficacy of asiatic acid (AA) on spinal cord injury (SCI) as well as the underlying mechanisms. MAIN METHODS Sprague-Dawley rats (n=150) were randomly assigned to five groups: sham, SCI, SCI+methylprednisolone (30mg/kg), SCI+AA (30mg/kg), and SCI+AA (75mg/kg). Motor function, histological changes, neutrophil infiltration, proinflammatory cytokine production, and oxidative stress as well as nuclear factor erythroid 2-related factor (Nrf)2, heme oxygenase (HO)-1, and nucleotide-binding domain-like receptor protein (NLRP)3 levels were evaluated. KEY FINDINGS AA treatment increased Basso, Beattie and Bresnahan scores and inclined plane test scores that were reduced by SCI. In addition, AA suppressed myeloperoxidase activity and reduced the levels of interleukin-1β, -18, and -6 and tumor necrosis factor-α as well as reactive oxygen species (ROS), H2O2, and malondialdehyde levels while increasing superoxide dismutase activity and glutathione production. AA treatment results in the upregulation in Nrf2/HO-1 levels and downregulation of NLRP3 inflammasome protein expression in SC tissue. SIGNIFICANCE AA protects against SCI via suppression of inflammation and oxidative stress. The underlying mechanism likely involves activation of Nrf2 and HO-1 and inhibition of ROS and the NLRP3 inflammasome pathway. AA has therapeutic potential for SCI treatment.

Abstract
Diospyros lotus is traditionally used for the treatment of diabetes, diarrhea, tumor, and hypertension. The purpose of this study was to investigate the anti-inflammatory effect and underlying molecular mechanisms of myricetin in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Myricetin dose-dependently suppressed the production of pro-inflammatory mediators (NO, iNOS, PGE2, and COX-2) in LPS-stimulated RAW264.7 macrophages. Myricetin administration decreased the production of NO, iNOS, TNF-α, IL-6, and IL-12 in mice. Myricetin decreased NF-κB activation by suppressing the degradation of IκBα, nuclear translocation of p65 subunit of NF-κB, and NF-κB DNA binding activity in LPS-stimulated RAW264.7 macrophages. Moreover, myricetin attenuated the phosphorylation of STAT1 and the production of IFN-β in LPS-stimulated RAW264.7 macrophages. Furthermore, myricetin induced the expression of HO-1 through Nrf2 translocation. In conclusion, these results suggest that myricetin inhibits the production of pro-inflammatory mediators through the suppression of NF-κB and STAT1 activation and induction of Nrf2-mediated HO-1 expression in LPS-stimulated RAW264.7 macrophages.
