[Ti] Título: Pectolinarigenin, an aglycone of pectolinarin, has more potent inhibitory activities on melanogenesis than pectolinarin. [So] Source: Biochem Biophys Res Commun;493(1):765-772, 2017 Nov 04. [Is] ISSN: 1090-2104 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: Pectolinarin and pectolinarigenin have been reported to be major compounds in Cirsium setidens. In the present study, we demonstrated inhibitory effects of pectolinarin and pectolinarigenin from C. setidens on melanogenesis. Melanin synthesis was decreased in both pectolinarin- and pectolinarigenin-treated melan-a cells and in a reconstructed human skin model. However, pectolinarigenin treatment showed more potent inhibitory activity of melanin synthesis than did pectolinarin treatment. The concentrations of pectolinarin and pectolinarigenin in C. setidens water extracts were determined by HPLC. Unfortunately, the amount of pectolinarigenin of C. setidens water extract was lower than that of pectolinarin. To increase the pectolinarigenin content in C. setidens water extract, several component conversion methods were studied. Consequently, we identified that microwave irradiation under 1% acetic acid was an optimum sugar elimination method.

[Ti] Título: Beneficial effects of a medicinal herb, Cirsium japonicum var. maackii, extract and its major component, cirsimaritin on breast cancer metastasis in MDA-MB-231 breast cancer cells. [So] Source: Bioorg Med Chem Lett;27(17):3968-3973, 2017 09 01. [Is] ISSN: 1464-3405 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: The biological activities of the ethanol extract from Cirsium japonicum var. maackii (ICF-1) and its major component, polyphenol cirsimaritin, were investigated as part of the search for possible alternative drugs for breast cancer. Three in vitro cell-based assays were used: the cell proliferation assay, tube-formation assay, and Western blot analysis. Both the ICF-1 extract and cirsimaritin inhibited the viability of HUVECs in a dose-dependent manner. The inhibition achieved was 36.89% at a level of 200µg/ml by the ICF-1 extract and 62.04% at a level of 100µM by cirsimaritin. The ICF-1 extract and cirsimaritin reduced tube formation by 12.69% at level of 25µg/ml and 32.18% at the levels of 6.25µM, respectively. Cirsimaritin inhibited angiogenesis by downregulation of VEGF, p-Akt and p-ERK in MDA-MB-231 cells, suggesting that cirsimaritin is potentially useful as an anti-metastatic agent. The present study demonstrated that Cirsium japonicum extract and its active component cirsimaritin is an excellent candidate as an alternative anti-breast cancer drug.

[Ti] Título: Anti-inflammatory effects and corresponding mechanisms of cirsimaritin extracted from Cirsium japonicum var. maackii Maxim. [So] Source: Bioorg Med Chem Lett;27(14):3076-3080, 2017 07 15. [Is] ISSN: 1464-3405 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: In this study, we investigated the anti-inflammatory effects and mechanisms of cirsimaritin isolated from an ethanol extract of the aerial parts of Cirsium japonicum var. maackii Maxim. using RAW264.7 cells. The extract and its flavonoid cirsimaritin inhibited nitric oxide (NO) production and inducible nitric oxide synthase expression in RAW264.7 cells. Cirsimaritin inhibited interleukin-6, tumor necrosis factor-α, and NO production in a concentration-dependent manner in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. From a western blot study, pretreatment with cirsimaritin inhibited phosphorylation/degradation of IκBα and phosphorylation of Akt in LPS-stimulated RAW264.7 cells. Moreover, cirsimaritin suppressed activation of LPS-induced transcription factors, such as c-fos and signal transducer and activator of transcription 3 (STAT3), in RAW264.7 cells. Collectively, these results show that cirsimaritin possesses anti-inflammatory activity, which is regulated by inhibition of c-fos and STAT3 phosphorylation in RAW264.7 cells.

[Ti] Título: The hemostatic effect study of Cirsium setosum on regulating α1-ARs via mediating norepinephrine synthesis by enzyme catalysis. [So] Source: Biomed Pharmacother;87:698-704, 2017 Mar. [Is] ISSN: 1950-6007 [Cp] País de publicação: France [La] Idioma: eng [Ab] Resumo: BACKGROUND: Cirsium setosum (CS) is the aboveground part of Cephalanoplos segetum Kitam. Although it has been used as a hemostatic treatment for thousands of years and is still in use today, the mechanism of CS on regulating ARs is still not clear. PURPOSE: In this study, we aimed to clarify the mechanism of CS on regulating ARs. METHODS: We developed a simple method based on UPLC/Q-TOF MS combined adrenergic receptor dual-luciferase reporter assay systems for the rapid determination of active constituents in CS. The mechanism of tyramine, the main active component for regulating ARs, was further investigated by an in vitro norepinephrine biotransformation test and in vivo vaso activity tests. RESULTS: Two phenethylamine ARs regulators (tyramine and N-methyltyramine) in CS were characterized, and it was found that tyramine could induce vasoconstriction via regulation of α1-ARs by mediating norepinephrine synthesis. CONCLUSION: The hemostatic effect of CS is associated with tyramine and N-methyltyramine, via regulation of α1-ARs, and the mechanism of tyramine is related to mediating norepinephrine synthesis by enzyme catalysis.

[Ti] Título: Antioxidant effects of Cirsium setidens extract on oxidative stress in human mesenchymal stem cells. [So] Source: Mol Med Rep;14(4):3777-84, 2016 Oct. [Is] ISSN: 1791-3004 [Cp] País de publicação: Greece [La] Idioma: eng [Ab] Resumo: Human mesenchymal stem cells (MSCs) may be used in cell-based therapy to promote neovascularization for the treatment of ischemic diseases. However, high levels of reactive oxygen species (ROS) derived from the pathophysiological ischemic environment induce senescence and apoptosis of MSCs, resulting in reduced functionality and defective neovascularization. Therefore, the present study aimed to determine the protective effects of Cirsium setidens, a natural product, on oxidative stress­induced apoptosis in MSCs. The present study investigated for the change of ROS levels in MSCs using ROS assays. In addition, cell viability determined by MTT and TUNEL assays. Western blot analysis was performed to investigate the change of apoptosis­associated proteins in MSCs. Treatment of MSCs with hydrogen peroxide (H2O2; 200 µM) significantly increased intracellular ROS levels and cell death; however, pretreatment with C. setidens (100 µg/ml) suppressed H2O2­induced ROS generation and increased the survival of MSCs. H2O2­induced ROS production increased the levels of phosphorylated­p38 mitogen activated protein kinase, c­Jun N­terminal kinase, ataxia telangiectasia mutated and p53; these increases were inhibited by pretreatment with C. setidens. In addition, C. setidens inhibited ROS­induced apoptosis of MSCs by increasing the expression levels of the anti­apoptotic protein B­cell lymphoma 2 (BCL­2), and decreasing the expression levels of the proapoptotic protein BCL­2­associated X protein. These findings indicated that pretreatment of MSCs with C. setidens may prevent ROS­induced oxidative injury by regulating the oxidative stress­associated signaling pathway, and suppressing the apoptosis­associated signal pathway. Therefore, C. setidens may be developed as a beneficial broad­spectrum agent for enhancing the effectiveness of MSC transplantation in the treatment of ischemic diseases.

[Ti] Título: A study on pyrolysis of Canada thistle (Cirsium arvense) with titania based catalysts for bio-fuel production. [So] Source: Bioresour Technol;219:175-184, 2016 Nov. [Is] ISSN: 1873-2976 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: The catalytic pyrolysis of Cirsium arvense was performed with titania supported catalysts under the operating conditions of 500°C, 40°C/min heating rate, 100mL/min N2 flow rate in a fixed bed reactor for biofuel production. The effect of catalysts on product yields was investigated. The amount of pyrolysis products (bio-char, bio-oil, gas) and the composition of the produced bio-oils were determined by proton nuclear magnetic resonance ((1)H NMR), Fourier transform infrared spectroscopy (FT-IR), gas chromatography/mass spectrometry (GC-MS) and elemental analysis (EA) techniques. Thistle bio-oils had lower O/C and H/C molar ratios compared to feedstock. The highest bio-char and bio-oil yields of 29.32wt% and 36.71wt% were obtained in the presence of Ce/TiO2 and Ni/TiO2 catalysts respectively. GC-MS identified 97 different compounds in the bio-oils obtained from thistle pyrolysis. (1)H NMR analysis showed that the bio-oils contained ∼55-77% aliphatic and ∼6-19% aromatic structural units.

[Ti] Título: Bio-statistical enhancement of acyl transfer activity of amidase for biotransformation of N-substituted aromatic amides. [So] Source: J Gen Appl Microbiol;62(2):90-7, 2016. [Is] ISSN: 1349-8037 [Cp] País de publicação: Japan [La] Idioma: eng [Ab] Resumo: Acyl transfer activity (ATA) of amidase transfers an acyl group of different amides to hydroxylamine to form the corresponding hydroxamic acid. Bacterial isolate BR-1 was isolated from cyanogenic plant Cirsium vulgare rhizosphere and identified as Pseudomonas putida BR-1 by 16S rDNA sequencing. This organism exhibited high ATA for the biotransformation of N-substituted aromatic amide to the corresponding hydroxamic acid. Optimization of media, tryptone (0.6%), inducer, pH 8.5, and a growth temperature 25°C for 56 h, resulted in a 7-fold increase in ATA. Further, Response Surface Methodology (RSM) and multiple feeding approach (20 mM after 14 h) of inducer led to a 29% enhancement of ATA from this organism. The half life (t1/2) of this enzyme at 50°C and 60°C was 3 h and 1 h, respectively. The ATA of amidase of Pseudomonas putida BR-1 makes it a potential candidate for the production of a variety of N-substituted aromatic hydroxamic acid.

[Ti] Título: Monogalactosyldiacylglycerol: An abundant galactosyllipid of Cirsium brevicaule A. GRAY leaves inhibits the expression of gene encoding fatty acid synthase. [So] Source: Phytomedicine;23(5):509-16, 2016 May 15. [Is] ISSN: 1618-095X [Cp] País de publicação: Germany [La] Idioma: eng [Ab] Resumo: BACKGROUND: The leaves of Cirsium brevicaule A. GRAY (CL) significantly decreased hepatic lipid accumulation and the expression of fatty acid synthase gene (FASN) in mice. PURPOSE: We aimed to purify and identify the active compound(s) from CL and determine the inhibitory mechanism of expression of FASN. METHODS: We purified monogalactosyldiacylglycerol (MGDG) from extracts of CL (CL-MGDG) and showed that it was the active CL component through analyses of its effects on the expression of genes of human breast cancer cell line, SKBR-3. RESULTS: The content and fatty acid composition of CL-MGDG are distinctly different from those of other vegetable-derived MGDGs. Treatment of SKBR-3 cells with MGDG decreased the level of FASN mRNA as well as the levels of mRNA encoding other protein involved in lipogenesis. Further, MGDG treatments significantly inhibited luciferase activities of constructs containing liver X receptor response element in FASN promoter region without altering the levels of mRNA encoding transcription factors. MGDG and the FASN inhibitor C75 decreased the viabilities of SKBR-3 cells in a concentration-dependent manner. CL-MGDG more potently inhibited cell viability than a commercial MGDG preparation. CONCLUSIONS: CL represents a good source of glycoglycerolipids with potential as functional ingredients of food.
