Abstract
Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder, characterized by abdominal pain, bloating, and changes in bowel habits. Huoxiang Drink (HD), derived from traditional Chinese medicine, has been reported to effectively treat digestive disorders caused by external cold and internal dampness. However, the pharmaceutical targets and mechanisms for HD against IBS remain unclear. Data mining, bioinformatics analysis, and network pharmacology were employed to explore the potential pharmacological mechanisms of HD against IBS. In this study, we screened 50 core targets to investigate the pharmacological mechanisms of HD against IBS. Enrichment analysis revealed that HD may participate in various signaling pathways, especially the inflammation-related tumor necrosis factor, signaling pathway and hypoxia-inducible factor signaling pathway. Molecular docking results confirmed that MOL000098 (Quercetin), MOL000006 (Luteolin), MOL005828 (Nobiletin), MOL005916 (Irisolidone), and MOL004328 (Naringenin), as key active ingredients in HD, bound to core targets (tumor protein P53, tumor necrosis factor, matrix metalloproteinases 9, and vascular endothelial growth factor-A) for topical treatment of IBS. This study suggested that HD offered a potential therapeutic strategy against IBS. Our findings may facilitate the efficient screening of active ingredients in HD and provide a theoretical basis for further validating the clinical therapeutic effects of HD on treating IBS.

BIOMATERIALS ADVANCES 2023; 148:213378.

Abstract
Intestinal vascular impairment is critical to the recovery of inflammatory bowel disease (IBD), and targeting vascular endothelial cells is a promising emerging therapeutic option. Considering the natural homing properties of platelets to activated vascular endothelium, platelet membrane-mimetic nanoparticles are expected to achieve precise treatment of IBD. Patchouli alcohol (PA) has proven efficacy in experimental colitis, yet its pharmacochemical properties require improvement to enhance efficacy. The rationale for targeting vascular lesions in IBD was analyzed by network pharmacology, and PA-affecting pathways were predicted. PA-encapsulated bio-nanoparticles (PNPs) were constructed to investigate the efficacy of agents on mouse intestinal microvascular endothelial cells (MIMVEC) inflammation model and dextran sulfate sodium (DSS)-induced acute mouse colitis model. PNPs were endocytosed by MIMVEC in vitro and efficiently enriched in inflamed colon. PNPs significantly alleviated the symptoms of experimental colitis and improved neutrophil infiltration. PNPs down-regulated LPS-induced aberrant elevation of il1β, tnfα and il6 mRNAs and reduced p65 phosphorylation in MIMVEC. Intracellular calcium expression, mitochondrial respiration and reactive oxygen species expression were also downregulated by PNPs. PNPs amplified the potency of PA as a calcium antagonist, restrained intracellular Ca2+ perturbations to prevent endothelial activation, which may block leukocyte recruitment in vivo to improve colitis.

Abstract
Two new lignans (1-2) and a new octaketide (12), together with twenty-nine known compounds (3-11, 13-32) were isolated and identified from the aerial part of Pogostemon cablin. Their chemical structures were revealed mainly through NMR and MS data. The absolute configuration of 1 and 2 was deduced by comparing its experimental CD with the calculated ECD spectra. The inhibitory activities of the isolated compounds on LPS-stimulated nitric oxide (NO) production in RAW 264.7 cells were investigated. At a concentration of 25 μM, compounds 1 and 11 showed approximately equal NO inhibitory effects to that of aminoguanidine.

Abstract
Pogostemonis Herba (PH) is the dried aerial parts of Pogostemon cablin (Blanco) Benth, which is mainly distributed and used in Asian countries. PH is an aromatic damp-resolving drug in traditional Chinese medicine (TCM), which is usually used for the treatment of vomiting, chest tension, tiredness, abdominal pain, diarrhea, and headache. In this review, the summary of chemical constituents in the aerial parts, biological activities, history of uses, quality control methods, industrial applications, pharmacokinetics and network pharmacology are reported. By collating the chemical constituents of various parts of PH, a total of 174 components were identified, including 66 terpenes, 6 pyrones, 40 flavonoids, 21 phenylpropanoids, 9 steroids, 4 polysaccharides and 28 others. Pharmacological research has found that PH possesses multi-pharmacological activities, including regulating the gastrointestinal tract, inhibition of pathogenic microorganisms, and anti-inflammation, which provide more scientific interpretation for the clinical usage of PH. In addition, the shortcomings of the current research on PH and the recommendation of future studies on PH are analyzed. We hope this review can provide some insight for further research and applications of PH in future.

Abstract
Pogostemon cablin Benth (PCB) is a well-known traditional Chinese medicine that has been used for treatment of many ailments for several centuries. In presently, the chemical profiling and quality control study of PCB has mainly concentrated on the volatile fractions. However, the non-volatile chemical profile of PCB was still unclear. In this study, 73 non-volatile constituents (i.e., 33 flavonoids, 21 organic acids, 9 phenylpropanoids, 4 sesquiterpenes, 3 alkaloids, and 3 other types of compounds) were identified and characterized in PCB using high performance liquid chromatography coupled with quadruple time-of-flight tandem mass spectrometry (HPLC-Q-TOF-MS). Meanwhile, to assess PCB samples, an established HPLC-Q-TOF-MS fingerprint was combined with multivariate statistical analysis that included similarity analysis (SA), hierarchical cluster analysis (HCA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA). The PCB samples could be classified into two groups (herbal decoction pieces and processed medicinal materials), and acteoside, isoacteoside, 4',6-Dihydroxy-5,7-dimethoxyflavone, pachypodol and pogostone were screened as the potential chemical markers that attributed classification. In addition, nine representative components (pachypodol, vicenin-2, apigenin, rhamnocitrin, acteoside, isoacteoside, chlorogenic acid, azelaic acid and pogostone) in PCB were simultaneously determined by using an ultra-high-performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry (UPLC-QQQ-MS/MS). This study is the first to describe the chemical profile of PCB using liquid chromatography tandem mass spectrometry, which would improve our understanding of the substance basis of PCB and is helpful to the PCB further quality evaluation.

Abstract
Obesity-induced chronic low-grade inflammation and thus causes various metabolic diseases, such as insulin resistance and non-alcoholic fatty liver disease (NAFLD). Patchouli alcohol (PA), an active component extracted from patchouli, displayed anti-inflammatory effects on different cell types. However, the impact of PA on skeletal muscle insulin signaling and hepatic lipid metabolism remains unclear. This study aimed to investigate whether PA would affect insulin signaling impairment in myocytes and lipid metabolism in hepatocytes. Treatment with PA ameliorated palmitate-induced inflammation and aggravation of insulin signaling in C2C12 myocytes and lipid accumulation in HepG2 hepatocytes. Treatment of C2C12 myocytes and HepG2 cells with PA augmented AMP-activated protein kinase (AMPK) phosphorylation and Sirtuin 1 (SIRT1) expression in a dose-dependent manner. siRNA-mediated suppression of AMPK or SIRT1 mitigated the effects of PA on palmitate-induced inflammation and insulin resistance in C2C12 myocytes and lipid accumulation in HepG2 cells. Animal experiments demonstrated that PA administration increased AMPK phosphorylation and SIRT1 expression, and ameliorated inflammation, thereby attenuating skeletal muscle insulin resistance and hepatic steatosis in high-fat diet-fed mice. These results denote that PA alleviates skeletal muscle insulin resistance and hepatic steatosis through AMPK/SIRT1-dependent signaling. This study might provide a novel therapeutic approach for treating obesity-related insulin resistance and NAFLD.

Abstract
Obesity impairs wound healing with substantial alterations in skin inflammation. Patchouli alcohol (PA), extracted from patchouli, has been reported to ameliorate inflammation in various cell types. However, the effects of PA on inflammation and wound healing have not been reported to date. In the present study, we examined whether PA affects cutaneous wound healing in high fat diet (HFD)-fed mice and explored PA-mediated molecular mechanisms through in vitro experiments. We found that PA administration accelerated wound healing as well as ameliorates inflammation in skin of HFD-fed mice. PA treatment augmented AMP-activated protein kinase (AMPK) phosphorylation and TGFb1 expression. PA enhanced cell migration and suppressed inflammation in LPS-treated HaCaT cells. Further, PA increased dose-dependently AMPK phosphorylation as along with TGFb1 and cell migration markers expression. siRNA for AMPK or TGFb1 abrogated the effects of PA on cell migration and inflammation. TGFb1 siRNA mitigated PA-induced expression of cell migration markers. These results suggest that PA ameliorates wound healing via AMPK and TGFb1-mediated suppression of inflammation. In sum, PA can be used as a novel treatment strategy for wound healing in obesity or insulin resistance.

Abstract
In this study, we investigated the relaxation effect and mechanisms of patchouli alcohol (PA) on rat corpus cavernosum. Corpus cavernosum strips were used in organ baths for isometric tension studies. The results showed that PA demonstrated concentration-dependent relaxation effect on rat corpus cavernosum. The relaxant response to PA was not influenced by tetrodotoxin and atropine while it was significantly inhibited by removal of endothelium. L-NG-nitroarginine methyl ester (L-NAME, a nitric oxide synthase inhibitor) or 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, a soluble guanylate cyclase inhibitor) significantly inhibited relaxation response to PA, whereas indomethacin (COX inhibitor) had no effect on PA-induced relaxation. The treatment of endothelium-deprived corpus cavernosum with several potassium channel blockers including tetraethylammonium (TEA), 4-aminopyridine (4-AP), and glibenclamide had no effect on PA-induced relaxation. Endothelium-deprived corpus cavernosal contractions induced by cumulative addition of Ca2+ to high KCl solution without CaCl2 were significantly inhibited by PA. Also, PA improved relaxant capacity of sildenafil in rat corpus cavernosum. In addition, the perfusion with PA significantly increased the levels of cGMP and expression of mRNA and protein of neuronal nitric oxide synthase (nNOS) and endothelial nitric oxide synthase (eNOS). Furthermore, intracavernous injection of PA enhanced the rise in intracavernous pressure in rats during cavernosal nerve electric stimulation. In conclusion, PA relaxed the rat corpus cavernosum attributed to both endothelium-dependent and -independent properties. While the former component was mostly involved in nitric oxide signaling pathway, the endothelium-independent mechanism involved in PA-induced relaxation was probably linked to calcium antagonism.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The pregnane-X-receptor (PXR) is involved in inflammatory bowel disease (IBD). Patchouli alcohol (PA) has anti-inflammatory effects; however, the effect of PA on IBD pathogenesis remains largely unknown. AIM OF THE STUDY The aim of the present study was to investigate the anti-inflammatory effect of PA, primarily focused on crosstalk between PA-mediated PXR activation and NF-κB inhibition. MATERIALS AND METHODS We evaluated the anti-inflammatory effect of PA with respect to PXR/NF-κB signalling using in vitro and in vivo models. In vitro, PA, identified as a PXR agonist, was evaluated by hPXR transactivation assays and through assessing for CYP3A4 expression and activity. NF-κB inhibition was analysed based on NF-κB luciferase assays, NF-κB-mediated pro-inflammatory gene expression, and NF-κB nuclear translocation after activation of PXR by PA. In vivo, colonic mPXR and NF-κB signalling were analysed to assess PA-mediated the protective effect against dextran sulphate sodium (DSS)-induced colitis. Furthermore, pharmacological inhibition of PXR was further evaluated by examining PA protection against DSS-induced colitis. RESULTS PA induced CYP3A4 expression and activity via an hPXR-dependent mechanism. PA-mediated PXR activation attenuated inflammation by inhibiting NF-κB activity and nuclear translocation. The anti-inflammatory effect of PA on NF-κB was abolished by PXR knockdown. PA prevented DSS-induced inflammation by regulating PXR/NF-κB signalling, whereas pharmacological PXR inhibition abated PA-mediated suppressive effects on NF-κB inflammation signalling. CONCLUSIONS PA activates PXR signalling and suppresses NF-κB signalling, consequently causing amelioration of inflammation. Our results highlight the importance of PXR-NF-κB crosstalk in colitis and suggest a novel therapeutic reagent.

Abstract
Inflammation plays a crucial role in the development of many complex diseases and disorders including autoimmune diseases, metabolic syndrome, neurodegenerative diseases, and cardiovascular pathologies. Prostaglandins play a regulatory role in inflammation. Cyclooxygenases are the main mediators of inflammation by catalyzing the initial step of arachidonic acid metabolism and prostaglandin synthesis. The differential expression of the constitutive isoform COX-1 and the inducible isoform COX-2, and the finding that COX-1 is the major form expressed in the gastrointestinal tract, lead to the search for COX-2-selective inhibitors as anti-inflammatory agents that might diminish the gastrointestinal side effects of traditional non-steroidal anti-inflammatory drugs (NSAIDs). COX-2 isoform is expressed predominantly in inflammatory cells and decidedly upregulated in chronic and acute inflammations, becoming a critical target for many pharmacological inhibitors. COX-2 selective inhibitors happen to show equivalent efficacy with that of conventional NSAIDs, but they have reduced gastrointestinal side effects. This review would elucidate the most recent findings on selective COX-2 inhibition and their relevance to human pathology, concretely in inflammatory pathologies characterized by a prolonged pro-inflammatory status, including autoimmune diseases, metabolic syndrome, obesity, atherosclerosis, neurodegenerative diseases, chronic obstructive pulmonary disease, arthritis, chronic inflammatory bowel disease and cardiovascular pathologies.

Pachypodol, a Methoxyflavonoid Isolated from Pogostemon cablin Bentham Exerts Antioxidant and Cytoprotective Effects in HepG2 Cells: Possible Role of ERK-Dependent Nrf2 Activation. Int J Mol Sci 2019; 20:ijms20174082. [PMID: 31438541 PMCID: PMC6747508 DOI: 10.3390/ijms20174082] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2019] [Revised: 08/14/2019] [Accepted: 08/19/2019] [Indexed: 01/28/2023] Open
Abstract
Oxidative stress has been implicated in the pathogenesis of many diseases including chronic liver diseases. Nrf2 is a master transcriptional factor regulating the induction of cellular antioxidant defense systems. Here, the Nrf2-activating effect of the crude methanol extract of dried leaves of Pogostemon cablin Bentham was demonstrated by measuring the antioxidant response element (ARE)-driven luciferase activity and pachypodol, 4′,5-dihydroxy-3,3′,7-trimethoxyflavone, was isolated by bioactivity-guided fractionation and further separation using chromatographic techniques. To our knowledge, this is the first study to evaluate the antioxidant and cytoprotective effects of pachypodol in HepG2 cells as well as the underlying molecular mechanisms. Indeed, pachypodol protected HepG2 cells from cell death caused by tert-butylhydroperoxide-induced oxidative stress and also attenuated ROS production. The ability of pachypodol to activate Nrf2/ARE pathway was further confirmed by observing Nrf2 expression in nuclear fraction, mRNA levels of Nrf2 target antioxidants, and cellular glutathione content in HepG2 cells. Extracellular signal-regulated kinase (ERK) is one of the important kinases involved in Nrf2 activation. Pachypodol increased ERK phosphorylation and ERK inhibition by PD98059 totally abrogated the increase in ARE luciferase activity, nuclear Nrf2 accumulation and mRNA levels of antioxidant enzymes by pachypodol. In conclusion, pachypodol isolated from P. cablin can protect hepatocytes from oxidative injury, possibly mediated by enhancing endogenous antioxidant defense system through ERK-dependent Nrf2 activation.

Abstract
Pogostemon cablin is an important commercial source of patchouli oil, whose main active ingredient is patchouli alcohol. This sesquiterpene is a product of the mevalonate pathway, in which 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGCR) is the rate-limiting enzyme. In this study, P. cablin HMGCR cDNA, comprising 2209 nucleotides encoding 425 amino acid residues was isolated, and bioinformatics analysis was used to analyze the protein sequence. Based on this analysis, a C-terminal truncated variant was engineered for recombinant expression in E. coli. The 38 kDa recombinant protein was identified by SDS-PAGE, and assayed for mevalonolactone production. According to the PcHMGCR1 gene sequence alignment with other species, the HMGCR protein had obvious resemblance with other plants HMG coenzyme A reductase and had homology with other species including plants, fungi, archaebacteria and animals. The prokaryotic expression vector was constructed by restriction enzyme digestion to be transformed into E. coli to express the recombinant protein, and 38 kDa recombinant protein was identified by the SDS-PAGE. Enzymatic activity was detected using GC-MS and, as a result, mevalonolactone was detected in the in vitro reaction mixture. Differential expression analysis showed that PcHMGCR1 expressed the highest amount in roots. The research results are of great significance for further research on the molecular biosynthesis mechanism of Patchouli alcohol in P. cablin.

Abstract
Brucea javanica is an important Chinese folk medicine traditionally used for the treatment of dysentery (also known as inflammatory bowel diseases). Brucea javanica oil emulsion (BJOE), the most common preparation of Brucea javanica, has a variety of pharmacological activities. In this follow-up investigation, we endeavored to illuminate the potential benefit of BJOE on 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced Crohn's disease (CD) in rats and decipher the mechanism of action. The result illustrated that BJOE treatment significantly reduced the body weight loss, disease activity index and macroscopic scores, ameliorated shortening of colon length, arrested colonic histopathological deteriorations, lowered the histological scores in parallel to the model group. Furthermore, BJOE also decreased the levels of MPO and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-17, IL-23 and IFN-γ), and increased the levels of anti-inflammatory cytokines (IL-4, IL-10 and TGF-β) as compared with the model group. In addition, the elevated mRNA expression of MMP-1, MMP-3 and RAGE induced by TNBS was remarkably inhibited by BJOE, SASP or AZA treatments, while the mRNA expression of PPAR-γ was significantly enhanced. Furthermore, the activation of TLR4/NF-κB signaling pathway was significantly inhibited by AZA and BJOE treatment when compared with that of TNBS-treated rats. Our study suggested that BJOE exerted superior therapeutic effect to SASP and AZA in treating TNBS-induced colitis in rats. The protective effect of BJOE may involve the inhibition of the TLR4/NF-κB-mediated inflammatory responses. These results indicated that BJOE held promising potential to be further developed into a novel candidate for the treatment of CD.

Abstract
Sinomenine (SIN), a pure alkaloid isolated from Sinomenium acutum, has been widely used in arthritis for its anti‑inflammatory effect, but little is known about the effect of SIN on human ulcerative colitis (UC). In the present study, the effect and mechanism of SIN was examined in a dextran sulfate sodium (DSS)‑induced murine colitis model, which mimics human UC. Oral administration of SIN significantly suppressed the elevated disease activity index and ameliorated colonic histological damage in a DSS‑induced colitis model. Tumor necrosis factor‑α, interleukin‑6 and inducible nitric oxide synthase levels were also reduced as detected by reverse transcription‑quantitative polymerase chain reaction. In addition, SIN reversed the decreased colon length and colonic superoxide dismutase activity. Furthermore, western blot analysis revealed that nuclear factor‑erythroid 2‑related factor 2 (Nrf2) and its downstream genes, heme oxygenase‑1 and NADP(H) quinone oxidoreductase 1 (NQO‑1), were markedly activated by SIN. The current results indicated that SIN alleviated DSS‑induced colitis in mice, which may be due to its antioxidant properties and was at least in part dependent on the Nrf2/NQO‑1 signaling pathway. Therefore, SIN may have potential applications as a protective drug for patients with UC.

Abstract
Background Hyperoside (Hyp) is a flavonoid glycoside compound that has been demonstrated to have anti-inflammatory, anti-apoptotic and antioxidant effects. However, the impact of Hyp on inflammatory bowel disease (IBD) has not been previously explored. Thus, we evaluated the role of Hyp in dextran sodium sulfate (DSS)-induced acute colitis in mice. Methods We established a mouse model of experimental acute colitis by treating mice with drinking water supplemented with 3.0% DSS for 7 days. The disease activity index (DAI), colon length, histological features and colonic malondialdehyde (MDA) levels were examined using appropriate methods, and COX-2 expression was examined by immunohistochemistry. TNF-α, IL-4, IL-6, IL-10, NF-κB p65, Bcl-2, Bax, Caspase-3, nuclear factor-erythroid 2-related factor 2 (Nrf2), hemeoxygenase-1 (HO-1) and superoxide dismutase (SOD) levels in colorectal tissues were detected by RT-PCR and western blotting. Results Hyp significantly attenuated DSS-induced changes in the DAI as well as DSS-induced colonic shortening and histological changes. Hyp also inhibited inflammation, a change reflected by decreases in TNF-α, IL-6, COX-2 and NF-κB p65 expression and increases in IL-10 expression. Hyp suppressed increases in the levels of apoptosis-related proteins, such as Caspase-3 and Bax, but upregulated the level of the anti-apoptotic protein Bcl2. In addition, Hyp also exerted antioxidant effects. The MDA content was decreased, and the expression of Nrf2 and its downstream targets HO-1 and SOD were increased by Hyp. Conclusions Based on these findings, Hyp possesses the ability to attenuate colitis, possibly by mitigating colonic inflammation and apoptosis via activation of the Nrf2 signaling pathway.

Abstract
Lindera glauca (Sieb. et Zucc.) Blume (Lauraceae) has been used to treat rheumatic arthritis, stroke, and cardiac pain. Phytochemical investigation of twigs of L. glauca (Sieb. et Zucc.) Blume resulted in the isolation and identification of a new cerebroside, glaucerebroside (1). The structure of 1 was elucidated by a combination of extensive spectroscopic analyses, including extensive 2D NMR, HR-MS, chemical reactions, and LC/MS analysis. Compound 1 is a relatively rare cerebroside with l-threo-configuration of the sphingosine part. This is the second example of identification of a cerebroside from the family Lauraceae. Compound 1 significantly inhibited nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated BV-2 cells, with an IC50 value of 23.84μM without inducing cell toxicity. This study suggests that glaucerebroside (1) can be an excellent candidate for development of novel anti-neuroinflammatory agents.

Abstract
This study further evaluated the in vitro and in vivo anti-Helicobacter pylori activities and potential underlying mechanism of patchouli alcohol (PA), a tricyclic sesquiterpene. In the in vitro assay, the capacities of PA to inhibit and kill H. pylori were tested on three standard strains at different pH values and on 12 clinical isolates. The effects of PA on H. pylori adhesion (and its alpA, alpB, and babA genes), motility (and its flaA and flaB genes), ultrastructure, and flagellation were investigated. Moreover, the H. pylori resistance to and postantibiotic effect (PAE) of PA were determined. Furthermore, the in vivo effects of PA on H. pylori eradication and gastritis were examined. Results showed that MICs of PA against three standard strains (pH 5.3 to 9) and 12 clinical isolates were 25 to 75 and 12.5 to 50 μg/ml, respectively. The killing kinetics of PA were time and concentration dependent, and its minimal bactericidal concentrations (MBCs) were 25 to 75 μg/ml. In addition, H. pylori adhesion, motility, ultrastructure, and flagellation were significantly suppressed. PA also remarkably inhibited the expression of adhesion genes (alpA and alpB) and motility genes (flaA and flaB). Furthermore, PA treatment caused a longer PAE and less bacterial resistance than clarithromycin and metronidazole. The in vivo study showed that PA can effectively eradicate H. pylori, inhibit gastritis, and suppress the expression of inflammatory mediators (COX-2, interleukin 1β, tumor necrosis factor alpha, and inducible nitric oxide synthase [iNOS]). In conclusion, PA can efficiently kill H. pylori, interfere with its infection process, and attenuate gastritis with less bacterial resistance, making it a potential candidate for new drug development.

Abstract
A new rearranged eudesmane sesquiterpene, named eudeglaucone (1), and five known sesquiterpenes including (+)-faurinone (2) and four eudesmane-type sesquiterpenes (3-6), were isolated from the twigs of Lindera glauca (Sieb. et Zucc.) Blume. The structure of 1 was elucidated by a combination of extensive spectroscopic analyses, including extensive 2D NMR (1H-1H COSY, HMQC, HMBC, and NOESY) and HR-MS. Compound 1 was a relatively rare rearranged eudesmane sesquiterpene in terpenoids. All isolates were evaluated for their antiproliferative activities against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and HCT-15). Compounds 3 and 6 showed significant cytotoxicity against SK-MEL-2 and HCT-15 cell lines with IC50 values ranging from 9.98 to 12.20 μM. We also investigated the anti-neuroinflammatory activities of the isolates (1-6) in the lipopolysaccharide (LPS)-stimulated murine microglia BV-2 cell line by measuring nitric oxide (NO) levels. All isolates significantly inhibited NO production with IC50 values of 3.67-26.48 μM without inducing cell toxicity.

Abstract
BACKGROUND Luteolin has a reputation for being a safe and effective natural antioxidant that has strong radical scavenging and cell protective properties. The role of oxidative stress in inflammatory bowel disease (IBD) has been well established and is increasingly highlighted. Thus, we studied the protective effect of luteolin administration in a mouse model of experimental colitis. METHODS Experimental acute colitis was induced by administering 3% dextran sulfate sodium (DSS) in the drinking water of mice for 7days. The disease activity index (DAI); colon length; histological assessment; mRNA levels of nuclear factor-erythroid 2-related factor 2 (Nrf2), tumor necrosis factor (TNF-α), interleukin-6 (IL-6), heme oxygenase-1 (HO-1), and NADP(H): quinone oxidoreductase 1 (NQO-1); protein expression of Nrf2 and inducible nitric oxide synthase (iNOS); colon malondialdehyde (MDA) levels; and the activity levels of colonic superoxide dismutase (SOD) and catalase (CAT) were examined. RESULTS Luteolin (20 and 50mg/kg) significantly attenuated the DAI, colon shortening and histological damage. In addition, luteolin administration effectively decreased the expression of inflammatory mediators, such as iNOS, TNF-α and IL-6. Luteolin also decreased the colonic content of MDA. The activities of colonic SOD and CAT and the levels of Nrf2 and its downstream targets, HO-1 and NQO1, were elevated by luteolin treatment. CONCLUSION These observations indicate that luteolin may suppress experimental colitis through the Nrf2 signaling pathway.

Molecules 2015; 20:8521-47. [PMID: 25985355 PMCID: PMC6272783 DOI: 10.3390/molecules20058521] [Citation(s) in RCA: 131] [Impact Index Per Article: 14.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2015] [Revised: 04/21/2015] [Accepted: 04/22/2015] [Indexed: 12/25/2022] Open
Abstract
Pogostemon cablin Benth. (patchouli) is an important herb which possesses many therapeutic properties and is widely used in the fragrance industries. In traditional medicinal practices, it is used to treat colds, headaches, fever, nausea, vomiting, diarrhea, abdominal pain, insect and snake bites. In aromatherapy, patchouli oil is used to relieve depression, stress, calm nerves, control appetite and to improve sexual interest. Till now more than 140 compounds, including terpenoids, phytosterols, flavonoids, organic acids, lignins, alkaloids, glycosides, alcohols, aldehydes have been isolated and identified from patchouli. The main phytochemical compounds are patchouli alcohol, α-patchoulene, β-patchoulene, α-bulnesene, seychellene, norpatchoulenol, pogostone, eugenol and pogostol. Modern studies have revealed several biological activities such as antioxidant, analgesic, anti-inflammatory, antiplatelet, antithrombotic, aphrodisiac, antidepressant, antimutagenic, antiemetic, fibrinolytic and cytotoxic activities. However, some of the traditional uses need to be verified and may require standardizing and authenticating the bioactivity of purified compounds through scientific methods. The aim of the present review is to provide comprehensive knowledge on the phytochemistry and pharmacological activities of essential oil and different plant extracts of patchouli based on the available scientific literature. This information will provide a potential guide in exploring the use of main active compounds of patchouli in various medical fields.

[PMID: 25981688 DOI: 10.1016/j.bmcl.2015.04.094] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2015] [Revised: 04/23/2015] [Accepted: 04/30/2015] [Indexed: 11/26/2022]
Abstract
A new octaketide, named cytosporone V (1), and two other known phenylethanoid glycosides (2-3), were isolated from the aerial parts of Pogostemon cablin (Blanco) Benth. The structure of 1 was elucidated by a combination of extensive spectroscopic analyses, including extensive 2D NMR and HR-MS. Compounds 1-3 displayed weak antibacterial activity against two gram-positive bacteria, Bacillus subtilis and Staphylococcus aureus. All isolates were also evaluated for their antiproliferative activities against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and HCT-15). Compounds 2 and 3 showed significant cytotoxicity against A549, SK-OV-3, SK-MEL-2, and HCT-15 cell lines with IC50 values ranging from 2.73 to 9.52 μM.
