Preliminary investigation of a combined herbal extract of Aruncus dioicus, Cirsium nipponicum, and Ocimum basilicum for halitosis.

BACKGROUND: Halitosis, the unpleasant odor in the oral cavity, has garnered increased attention and concern due to the growing significance of social interaction. SGE-107, a blend of 3 botanical drugs-Korean goat's beard, Cirsium tanakae, and Basil-with caffeic acid as its indicator component. This study aims to investigate the efficacy of SGE-107 in treating halitosis in patients with mild gastrointestinal symptoms. METHODS: We enrolled 25 participants with oral malodor and dyspeptic symptoms. We assessed the severity of halitosis using the visual analog scale. Throughout a 4-week period of administering SGE-107, we evaluated both objective and subjective parameters, including the halitosis-associated life-quality test, the Korean gastrointestinal symptom rating scale, levels of volatile sulfur compounds, salivary flow rate, oral moisture, tongue index, Winkel tongue coating index, and tongue temperature. RESULTS: After the intervention period, both the visual analog scale (5.88 ±â€…1.03 vs 2.38 ±â€…0.93, P < .001) and the scores of the halitosis-associated life-quality test (31.21 ±â€…11.78 vs 13.83 ±â€…6.38, P < .001) showed significant reductions. The proportion of participants with abnormal levels of methyl mercaptan (a volatile sulfur compound) also significantly decreased (17, 70.8% vs 9, 37.5%, P = .039). Furthermore, there were significant improvements in reflux, constipation, diarrhea, and the total scores on the Korean gastrointestinal symptom rating scale. Throughout the study period, only 2 participants experienced mild adverse events. CONCLUSION: SGE-107 appears to be a safe and effective treatment for halitosis-associated with gastrointestinal symptoms; nevertheless, the limited sample size necessitates further large-scale randomized, controlled studies to confirm our findings.

Potential Antioxidant and Anti-Inflammatory Properties of Polyphenolic Compounds from Cirsium japonicum Extract.

Cirsium japonicum is a medicinal plant that has been used due to its beneficial properties. However, extensive information regarding its therapeutic potential is scarce in the scientific literature. The antioxidant and anti-inflammatory potential of polyphenols derived from the Cirsium japonicum extracts (CJE) was systematically analyzed. High-performance liquid chromatography (HPLC) with mass spectrometry (MS) was used to examine the compounds in CJE. A total of six peaks of polyphenol compounds were identified in the extract, and their MS data were also confirmed. These bioactive compounds were subjected to ultrafiltration with LC analysis to assess their potential for targeting cyclooxygenase-2 (COX2) and DPPH. The outcomes showed which primary compounds had the highest affinity for binding both COX2 and DPPH. This suggests that components that showed excellent binding ability to DPPH and COX2 can be considered significant active substances. Additionally, in vitro analysis of CJE was carried out in macrophage cells after inducing inflammation with lipopolysaccharide (LPS). As a result, it downregulated the expression of two critical pro-inflammatory cytokines, COX2 and inducible nitric oxide synthase (iNOS). In addition, we found a solid binding ability through the molecular docking analysis of the selected compounds with inflammatory mediators. In conclusion, we identified polyphenolic compounds in CJE extract and confirmed their potential antioxidant and anti-inflammatory effects. These results may provide primary data for the application of CJE in the food and pharmaceutical industries with further analysis.

Californian thistle (Cirsium arvense): endophytes and Puccinia punctiformis.

Californian thistle (Cirisum arvense) is a troublesome weed in pastures and cropping systems. The fungal biocontrol agent Puccinia punctiformis, commonly referred to as thistle rust, performs inconsistently on C. arvense. Problems with P. punctiformis establishment and control of C. arvense may be attributable to differing plant endophytic populations in various environments. This article provides an overview of the relationships between endophytes and their host, but also between endophytes and pathogens with a focus on rust pathogens. This review provides insights into reasons why P. punctiformis performs inconsistently and identifies gaps in our knowledge. Filling these gaps may help to improve performance of this classical fungal biocontrol agent. © 2023 The Authors.

Comparative Contents of Polyphenolic Compounds in Aerial Parts of Cirsium esculentum, C. serratuloides, and Ancathia igniaria (Asteraceae).

Because Ancathia igniaria (Spreng.) DC. (Cirsium igniarium Spreng.) has been segregated as a monotypic genus from the genus Cirsium on the basis of phylogenetic data, chemotaxonomic differences are of interest to detect in the composition of polyphenolic components of aerial plant parts. Phenolic compounds are of chemotaxonomic significance in a number of genera and families. The polyphenolic profile of aerial parts was therefore compared for Cirsium esculentum (Siev.) C.A. Mey., Cirsium serratuloides (L.) Hill, and A. igniaria. The last two species were for the first time examined in this context. The compounds were identified against known standard via high-performance liquid chromatography (HPLC). The species of the genus Cirsium were found to have similar compositions of simple phenols, but differ in the set of flavonoids. Six to eight phenolic compounds were detected in the species, and three simple polyphenols (syringin, chlorogenic acid, and ethyl gallate) proved to be common. The flavonoid profiles of aerial parts included rutin in both Cirsium species. Cymaroside and quercetin-3-O-ß-D-diglucoside-O-α-L-rhamnoside were species specific for C. serratuloides; salipurposide and hyperoside, for C. esculentum. An extract of A. igniaria aerial parts contained cinaroside (like in C. serratuloides), chrysin 7-O-glucoside, and eriodictyol. A greater difference in flavonoid composition was observed between the genera Cirsium and Ancathia. Data on phenolic compound composition are of importance for chemosystematics and use of plants as medicinal raw materials. The total content of coumarins, aglycones, and flavonoid glycosides in the species was determined by a spectrophotometric method. The contents of flavonoids and coumarins in C. esculentum and C. serratuloides were comparable and exceeded their contents in A. igniaria. Thus, A. igniaria proved to differ from the genus Cirsium in the quantitative and qualitative composition of phenolic compounds.

Effects of Cirsium palustre Extracts and Their Main Flavonoids on Colon Motility-An Ex Vivo Study.

For centuries, various species from the genus Cirsium have been utilized in traditional medicine worldwide. A number of ethnopharmacological reports have pointed out that Cirsium plants can be applied to diminish digestive problems. Among them, Cirsium palustre (L.) Scop. (Asteraceae) stands out as a promising herbal drug candidate because its constituents exhibit antimicrobial and antioxidant potential, as evidenced by ethnopharmacological reports. As a result, the species is particularly intriguing as an adjunctive therapy for functional gastrointestinal and motility disorders. Our research goal was to verify how the extracts, fractions, and main flavonoids of C. palustre affect colon contractility under ex vivo conditions. An alternative model with porcine-isolated colon specimens was used to identify the effects of C. palustre preparations and their primary flavonoids. LC-ESI-MS was utilized to evaluate the impacts of methanol (CP1), methanolic 50% (CP2), and aqueous (CP3) extracts as well as diethyl ether (CP4), ethyl acetate (CP5), and n-butanol (CP6) fractions. Additionally, the impacts of four flavonoids, apigenin (API), luteolin (LUT), apigenin 7-O-glucuronide (A7GLC), and chrysoeriol (CHRY), on spontaneous and acetylcholine-induced motility were assessed under isometric conditions. The results showed that C. palustre extracts, fractions, and their flavonoids exhibit potent motility-regulating effects on colonic smooth muscle. The motility-regulating effect was observed on spontaneous and acetylcholine-induced contractility. All extracts and fractions exhibited an enhancement of the spontaneous contractility of colonic smooth muscle. For acetylcholine-induced activity, CP1, CP2, and CP4 caused a spasmolytic effect, and CP5 and CP6 had a spasmodic effect. LUT and CHRY showed a spasmolytic effect in the case of spontaneous and acetylcholine-induced activity. In contrast, API and A7GLC showed a contractile effect in the case of spontaneous and pharmacologically induced activity. Considering the results obtained from the study, C. palustre could potentially provide benefits in the treatment of functional gastrointestinal disorders characterized by hypomotility and hypermotility.

Antimicrobial and Antioxidant Efficacy of the Lipophilic Extract of Cirsium vulgare.

The aim of this study was to investigate the compounds in the hexane extract of Cirsium vulgare (Savi.) Ten. and to determine the antibacterial, antifungal, and antioxidant activities of different extracts. The Cirsium vulgare (NGBB 7229) plant was collected from Turkey's Trakya region. Crude extracts were obtained using different solvents. The chemical composition of Cirsium vulgare was determined in hexane extract using gas chromatography mass spectrometry. The antioxidant activities of the extracts were evaluated by Trolox equivalent antioxidant activity (TEAC), ferric-reducing antioxidant power (FRAP), cupric-reducing antioxidant capacity (CUPRAC), the ß-carotene bleaching method, and the determination of superoxide anion scavenging activities. The antibacterial activity was tested against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis, and Salmonella typhimurium, whereas the antifungal activity was tested against Candida albicans, Candida glabrata, Candida parapsilosis, Candida krusei, Penicillium chrysogenum, and Aspergillus fumigatus by applying microdilution methods. A total of 41 bioactive compounds were identified using the GC-MS library. Terpenoids were found to be dominant (52.89%), and lup-20(29)-en-3-yl-acetate and lupeol were the most abundant terpenoids. The highest total flavonoid content (25.73 mg catechin/g) and antioxidant capacity were found in the methanolic extract. The highest antibacterial activity was detected against Bacillus subtilis in the ethyl acetate extract, and the highest antifungal activity was found against Candida krusei and Aspergillus fumigatus in the hexane extract. The observed antioxidant characteristics of the C. vulgare extracts could be attributed to the presence of flavonoids. The high antifungal activity of the hexane extract against all fungal strains can be attributed to its constituents, i.e., terpenoids. This study discloses the potential antioxidant and antimicrobial activities, including some bioactive components, of Cirsium vulgare and implies that Cirsium vulgare holds possible applications in the food and pharmaceutical industries as an antioxidant, antibacterial, and antifungal agent.

Methanol Extracts from Cirsium japonicum DC. var. australe Kitam. and Their Active Components Reduce Intracellular Oxidative Stress in Caenorhabditis elegans.

Cirsium japonicum DC. var. australe Kitam. has been used as an herbal remedy and often involves using the whole plant or roots. However, the bioactivities of different parts of the plant have been far less explored. This study aimed to evaluate the antioxidative ability of methanol extracts from the flowers, leaves, stems, and roots of the Cirsium plant and their possible active components against juglone-induced oxidative stress in the nematode Caenorhabditis elegans. The results showed that the highest dry weight (12.3 g per plant) was observed in leaves, which was followed by stems (8.0 g). The methanol extract yields from the flowers, leaves, and roots were all similar (13.0-13.8%), while the yield from stems was the lowest (8.6%). The analysis of the silymarin contents in the extracts indicated that the flowers, leaves, stems, and roots contained silychristin and taxifolin; however, silydianin was only found in the leaves, stems, and roots. The flower, leaf, and stem extracts, at a concentration of 10 mg/L, significantly reduced juglone-induced oxidative stress in C. elegans, which was potentially due to the presence of silychristin and taxifolin. Overall, C. japonicum DC. var. australe Kitam. contains a significant amount of silymarin and exhibits in vivo antioxidative activity, suggesting that the prospects for the plant in terms of health supplements or as a source of silymarin are promising.

Invasive Cirsium arvense displays different resource-use strategies along local habitat heterogeneity in the trans-Himalayan region of Ladakh.

Climate change and anthropogenic pressures have resulted in a significant shift in the invasion susceptibility and frequency of non-native species in mountain ecosystems. Cirsium arvense (L.) Scop. (Family: Asteraceae) is an invasive species that spreads quickly in mountains, especially in the trans-Himalayan region of Ladakh. The current study used a trait-based approach to evaluate the impact of local habitat heterogeneity (soil physico-chemical properties) on C. arvense. Thirteen plant functional traits (root, shoot, leaf, and reproductive traits) of C. arvense were studied in three different habitat types (agricultural, marshy, and roadside). Functional trait variability in C. arvense was higher between, than within habitats (between different populations). All the functional traits interacted with habitat change, except for leaf count and seed mass. Soil properties strongly affect C. arvense's resource-use strategies across habitats. The plant adapted to a resource-poor environment (roadside habitat) by conserving resources and to a resource-rich environment (agricultural and marshy land habitat) by acquiring them. The ability of C. arvense to use resources differently reflects its persistence in introduced habitats. In summary, our study shows that C. arvense invades different habitats in introduced regions through trait adaptations and resource-use strategies in the trans-Himalayan region.

Distinctive origin and evolution of endemic thistle of Korean volcanic island: Structural organization and phylogenetic relationships with complete chloroplast genome.

Unlike other Cirsium in Korea, Cirsium nipponicum (Island thistle) is distributed only on Ulleung Island, a volcanic island off the east coast of the Korean Peninsula, and a unique thistle with none or very small thorns. Although many researchers have questioned the origin and evolution of C. nipponicum, there is not much genomic information to estimate it. We thus assembled the complete chloroplast of C. nipponicum and reconstructed the phylogenetic relationships within the genus Cirsium. The chloroplast genome was 152,586 bp, encoding 133 genes consisting of 8 rRNA genes, 37 tRNA genes, and 88 protein-coding genes. We found 833 polymorphic sites and eight highly variable regions in chloroplast genomes of six Cirsium species by calculating nucleotide diversity, as well as 18 specific variable regions distinguished C. nipponicum from other Cirsium. As a result of phylogenetic analysis, C. nipponicum was closer to C. arvense and C. vulgare than native Cirsium in Korea: C. rhinoceros and C. japonicum. These results indicate that C. nipponicum is likely introduced through the north Eurasian root, not the mainland, and evolved independently in Ulleung Island. This study contributes to further understanding the evolutionary process and the biodiversity conservation of C. nipponicum on Ulleung Island.

Genome sequence and characterization of a novel fabavirus infecting Cirsium setidens (gondre) in South Korea.

The complete nucleotide sequence of a novel gondre (Cirsium setidens)-infecting virus, provisionally named "cirsium virus A" (CiVA), was determined by high-throughput and Sanger sequencing, revealing a genome organization typical of fabaviruses. RNA1 and RNA2 are 5,828 and 3,478 nucleotides long, excluding the 3'-terminal poly(A) tails, each containing a single open reading frame. The highest sequence identity values for the CiVA coat protein and proteinase-polymerase, compared with known fabavirus sequences, were 59.09% and 69.68%, respectively, falling below the current thresholds for Fabavirus species demarcation. Our findings support classifying CiVA as a novel putative member of the genus Fabavirus, subfamily Comovirinae, family Secoviridae.

Cirsium Setidens Water Extracts Containing Linarin Block Estrogen Deprivation-Induced Bone Loss in Mice.

Osteoporosis is evident in postmenopausal women and is an osteolytic disease characterized by bone loss that further increases the susceptibility to bone fractures and frailty. The use of complementary therapies to alleviate postmenopausal osteoporosis is fairly widespread among women. Edible Cirsium setidens contains various polyphenols of linarin, pectolinarin, and apigenin with antioxidant and hepatoprotective effects. This study aimed to determine whether Cirsium setidens water extracts (CSEs), the component linarin, and its aglycone acacetin blocked ovariectomy (OVX)-induced bone loss. This study employed OVX C57BL/6 female mice as a model for postmenopausal osteoporosis. CSEs, acacetin, or linarin was orally administrated to OVX mice at a dose of 20 mg/kg for 8 weeks. Surgical estrogen loss in mice for 8 weeks reduced bone mineral density (BMD) of mouse femur and serum 17ß-estradiol level and enhanced the serum receptor activator of NF-κB ligand/osteoprotegerin ratio with uterine atrophy. CSEs and linarin reversed such adverse effects and enhanced femoral BMD in OVX mice. Oral administration of CSEs and linarin attenuated tartrate-resistant acid phosphate activity and the induction of αvß3 integrins and proton suppliers in resorption lacunae in femoral bone tissue of OVX mice. In addition, CSEs and linarin curtailed the bone levels of cathepsin K and matrix metalloproteinase-9 responsible for osteoclastic bone resorption. On the other hand, CSEs and linarin enhanced the formation of trabecular bones in estrogen-deficient femur with increased induction of osteocalcin and osteopontin. Further, treatment with CSEs and linarin enhanced the collagen formation-responsive propeptide levels in the circulation along with the increase in the tissue non-specific alkaline phosphatase level in bone exposed to OVX. Supplementing CSEs, acacetin, or linarin to OVX mice elevated the formation of collagen fibers in OVX trabecular bone, evidenced using Picrosirius red staining. Accordingly, CSEs and linarin were effective in retarding osteoclastic bone resorption and promoting osteoblastic bone matrix mineralization under OVX conditions. Therefore, linarin, which is abundant in CSEs, may be a natural compound for targeting postmenopausal osteoporosis and pathological osteoresorptive disorders.

Five centuries of Cirsium ehrenbergii Sch. Bip. (Asteraceae) in Mexico, from Huitzquilitl to Cardo Santo: History, ethnomedicine, pharmacology and chemistry.

ETHNOPHARMACOLOGICAL RELEVANCE: Several medicinal plants, including the endemic herb Cirsum ehrenbergii (Asteraceae), have been documented in manuscripts, medical and botanical books written in Mexico since the XVI century until the present. This unique circumstance is a real window in the time that allows to investigate historical and contemporary ethnopharmacological knowledge. AIM OF THE STUDY: To examine the persistence, disappearance, and transformation of ethnomedicinal knowledge of C. ehrenbergii along time. Also, to investigate the chemistry and pharmacology of this species in relation to its historical and present day main ethnomedical applications related to Central Nervous System and inflammation. MATERIALS AND METHODS: A thorough review was performed of written sources of medicinal plants from XVI and onwards. For the pharmacological studies, the organic extracts were tested in mice models to assess its antidepressant and anti-inflammatory properties. The active extracts were studied chemically. The isolated compounds were identified by 1H, 13C NMR, or characterized by GC-MS. RESULTS: Cirsum ehrenbergii was illustrated for the first time (1552) in the Libellus de Medicinalibus Indorum Herbis (Booklet of Medicinal Plants of the Indians) and named in the Nahuatl native language as huitzquilitl (edible thistle). It was there recommended as nigris sanguinis remedium (remedy for black blood), and for the treatment of illnesses with an inflammatory component. Nigris sanguinis was well known in the European medicine of that time and currently it has been interpreted as "depression". At the present time, peasants and native population in Mexico mainly name C. ehrenbergii in Spanish as cardo Santo (holy thistle). Its original Nahuatl name has been almost forgotten. However, these communities use this species, among other maladies, to heal "nervios" (anxiety and/or depression) and for anti-inflammatory purposes. These ailments and treatments resemble those recorded in the Libellus and in several medicinal plant books along centuries. The ethanol extract of C. ehrenbergii roots showed antidepressant-like activity in mice administered at 300 mg/kg, as indicated by the forced swim test (FST). The glycosylated flavonoid linarin was identified as antidepressant principle and was active at the doses of 30 and 60 mg/kg in the FST. Regarding to anti-inflammatory activity, the most active was the methylene chloride extract of the aerial parts, which contains taraxasterol, pseudotaraxasterol, ß-sitosterol and stigmasterol. CONCLUSIONS: Cirsium ehrenbergii extracts possess antidepressant-like (roots, EtOH) and anti-inflammatory (aerial parts, CH2Cl2) properties, containing active compounds. Our results sustain historical and present day ethnomedical applications of this species documented along five centuries.

Purification Process and In Vitro and In Vivo Bioactivity Evaluation of Pectolinarin and Linarin from Cirsium japonicum.

Pectolinarin and linarin are two major flavone O-glycosides of Cirsium japonicum, which has been used for thousands of years in traditional Chinese medicine. Pharmacological research on pectolinarin and linarin is meaningful and necessary. Here, a process for the purification of pectolinarin and linarin from C. japonicum was established using macroporous resin enrichment followed by prep-HPLC separation. The results show the purity of pectolinarin and linarin reached 97.39% and 96.65%, respectively. The in vitro bioactivities result shows the ORAC values of pectolinarin and linarin are 4543 and 1441 µmol TE/g, respectively, meanwhile their inhibition rate of BSA-MGO-derived AGEs is 63.58% and 19.31% at 2 mg/mL, which is 56.03% and 30.73% in the BSA-fructose system, respectively. The COX-2 inhibition rate at 50 µg/mL of linarin and pectolinarin reached 55.35% and 40.40%, respectively. Furthermore, the in vivo bioassay combining of histopathologic evaluation and biochemical analysis of liver glutamic oxaloacetic transaminase, serum creatinine and TNF-α show pectolinarin can alleviate lipopolysaccharide (LPS)-induced acute liver and kidney injury in mice. Metabolomics analysis shows that pectolinarin attenuates LPS-challenged liver and kidney stress through regulating the arachidonic acid metabolism and glutathione synthesis pathways. Collectively, our work presents a solid process for pectolinarin and linarin purification and has discovered a promising natural therapeutic agent-pectolinarin.

Biologically synthesis of gold nanoparticles using Cirsium japonicum var. maackii extract and the study of anti-cancer properties on AGS gastric cancer cells.

Plant extract-mediated synthesis of metal nanoparticles (NPs) is an eco-friendly and cost-effective biosynthesis method that is more suitable for biological applications than chemical ones. We prepared novel gold NPs (AuNPs), Cirsium japonicum mediated-AuNPs (CJ-AuNPs), using a biosynthetic process involving Cirsium japonicum (Herba Cirsii, CJ) ethanol extract. The physicochemical properties of CJ-AuNPs were characterized using spectrometric and microscopic analyses. The in vitro stability of CJ-AuNPs was studied for 3 months. Moreover, the selective human gastric adenocarcinoma (AGS) cell killing ability of CJ-AuNPs was verified in cancer and normal cells. An in vitro study revealed that CJ-AuNPs trigger oxidative stress and iron-dependent ferroptosis in AGS cells. Mechanistically, CJ-AuNPs induced mitochondrial reactive oxygen species (ROS), Fe2+, and lipid peroxidation accumulation, and mitochondrial damage by destroying the glutathione peroxidase-4 (GPX4)-dependent antioxidant capacity. Furthermore, in a xenograft mouse model implanted with AGS cells, treatment with 2.5, 5, and 10 mg/kg CJ-AuNPs for 16 days reduced tumor xenograft growth in a dose dependent manner in vivo without systemic toxicity. These results demonstrate that CJ-AuNPs exert anticancer effects in vitro and in vivo by inducing ferroptosis-mediated cancer cell death. This study, based on green-synthesized nanodrug-induced ferroptosis, provides new insight into potential developments in cancer therapies.

Polyacetylenes from the roots of Cirsium japonicum var. ussuriense.

Eight previously undescribed polyacetylenes, cirussurynes A-H, were isolated from the methanolic extract of the roots of Cirsium japonicum var. ussuriense. Their structures were elucidated by interpretation of extensive 1D and 2D NMR spectroscopy and HRESIMS spectrometry data. The configuration of triols in cirussurynes A, B, and E-G was deduced by the J-value based configuration analysis together with specific rotation values. All compounds were evaluated for their inhibitory effects on nitric oxide production against LPS-induced RAW 264.7 macrophages, and exhibited IC50 values ranging from 5.5 to 68.7 µM.

Anti-inflammatory effects of the Aralia elata and Cirsium japonicum in Raw264.7 cells and in vivo colitis model in mice and dogs.

Ulcerative colitis (UC) is a severe inflammatory disease that has spread throughout the world. Cirsium japonicum (CJ) and Aralia elata (AE) are natural herbs with potent antioxidative antidiabetics and anti-inflammatory effects. In this investigation, we studied the defensive role of the combination of CJ and AE against LPS-induced inflammation in RAW 264.7 cells, dextran sulfate sodium (DSS)-induced colitis in mice, and acetic acid-induced colitis in dogs. MTT assay was performed to identify the toxic effect of CJ and AE extracts. NO, and MDA level was also measured by NO and MDA assay. To measure the pro-inflammatory protein expression, a western blot was performed. To induce colitis, 3% DSS was used for mice and 6% acetic acid was used for dogs. Histopathology and colonoscopy were executed to detect the effect of extracts. CJ and AE pretreatment reduced the level of NO, MDA, and the expression of pro-inflammatory proteins cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNF-α), and interleukin-1ß (IL-1ß) in RAW 264.7. Compared to the separate doses of CJ and AE, the combined dose of CJ and AE significantly reduced clinical symptoms induced by DSS in mice and acetic acid in dogs including weight loss, bloody stool, shortening of the colon, and the severity of colitis and degree of histological damage in the colon. Therefore, these results indicated that a combined dose of CJ and AE has a protective effect against LPS-induced RAW 264.7 cells, DSS-mediated colonic inflammation in mice, and acetic acid-induced colitis in dogs.

Effect of Cirsium japonicum Flower Extract on Skin Aging Induced by Glycation.

Advanced glycation end products (AGEs) have recently been increasingly discussed as one factor of skin aging. In this study, we investigated the effects of Cirsium japonicum flower (CFE) extract on glycation in relation to skin aging and skin elasticity. Moreover, we learned the main active constituent of CFE that has effects against glycation. To demonstrate the effects of CFE on glycation, we carried out an in vitro glycation study, 3-dimensional culture, and clinical study. As a result, CFE inhibited formation of AGEs in both bovine serum albumin (BSA)/glucose glycation system and aldehyde-derived glycation system. Moreover, CFE reduced Nε-(carboxymethyl), lysine (CML), and carbonylated proteins that increased by glycation. Furthermore, CFE broke crosslinks of collagen-AGEs and inhibited the increase of matrix metalloproteinase-1 (MMP-1) gene expression by AGEs. In the 3D culture condition, CFE restored the reduction of collagen gel contraction by glycation. Moreover, apigenin was detected as the main active constituent in CFE that has anti-glycation effects. In the clinical study, we confirmed that CFE has effects on skin wrinkles and skin elasticity. Our findings suggest that CFE can be used as a cosmetic or cosmeceutical ingredient for improving skin elasticity and wrinkles. Regulation of AGEs can be an interesting target for anti-aging.

A Complex of Cirsium japonicum var. maackii (Maxim.) Matisum. and Thymus vulgaris L. Improves Menopausal Symptoms and Supports Healthy Aging in Women.

We evaluated the efficacy and safety of MS-10® for the treatment of menopausal symptoms. A double-blind randomized placebo-controlled clinical trial was performed in 71 premenopausal women for 4 and 12 weeks. A total of 12 individual menopausal symptom scores were assessed using the Kupperman index. MS-10 treatment effectively improved the symptoms by ∼48%. In addition, the quality of life of the women improved by 36% from four perspectives: vasomotor, psychosocial, physical, and sexual symptoms as evaluated using the menopause-specific quality of life (MenQoL) questionnaire. Our results show that MS-10 improves insulin-like growth factor-1 (IGF-1) and estrogen utilization through receptor activation, which are thought to have causative therapeutic effects on menopause and aging inhibition in women. Improvement of Enthotheline-1 (ET-1) in the blood after MS-10 intake led to an improvement in menopausal vascular symptoms. Improvements in bone formation and absorption markers such as osteocalcin, bone-specific alkaline phosphatase (BSALP), C-telopeptides of type I collagen (CTx), deoxypyridinoline (deoxyPYD), and N-telopeptides of type I collagen (NTx) in blood or urine indicate that MS-10 fundamentally improves bone health in women. By confirming the improvement of the psychological well-being index based on the improvement of stress hormone cortisol, MS-10 can solve causative psychological and physical stress-related symptoms. Moreover, various safety tests, such as those for female hormones, were confirmed. Therefore, it can be confirmed that MS-10 is a natural pharmaconutraceutical that causatively and safely improves health of women and aids in antiaging processes.

Cirsium japonicum var. Maackii Improves Cognitive Impairment under Amyloid Beta25-35-Induced Alzheimer's Disease Model.

Abnormal production and degradation of amyloid beta (Aß) in the brain lead to oxidative stress and cognitive impairment in Alzheimer's disease (AD). Cirsium japonicum var. maackii (CJM) is widely used as an herbal medicine and has antibacterial and anti-inflammatory properties. This study focused on the protective effect of the ethyl acetate fraction from CJM (ECJM) on Aß 25-35-induced control mice. In the T-maze and novel object recognition test, ECJM provided higher spatial memory and object recognition compared to Aß 25-35 treatment alone. In the Morris water maze test, ECJM-administered mice showed greater learning and memory abilities than Aß 25-35-induced control mice. Additionally, ECJM-administered mice experienced inhibited lipid peroxidation and nitric oxide production in a dose-dependent manner. The present study indicates that ECJM improves cognitive impairment by inhibiting oxidative stress in Aß 25-35-induced mice. Therefore, CJM may be useful for the treatment of AD and may be a potential material for functional foods.

Network Pharmacology-Based Study to Uncover Potential Pharmacological Mechanisms of Korean Thistle (Cirsium japonicum var. maackii (Maxim.) Matsum.) Flower against Cancer.

Cirsium japonicum var. maackii (Maxim.) Matsum. or Korean thistle flower is a herbal plant used to treat tumors in Korean folk remedies, but its essential bioactives and pharmacological mechanisms against cancer have remained unexplored. This study identified the main compounds(s) and mechanism(s) of the C. maackii flower against cancer via network pharmacology. The bioactives from the C. maackii flower were revealed by gas chromatography-mass spectrum (GC-MS), and SwissADME evaluated their physicochemical properties. Next, target(s) associated with the obtained bioactives or cancer-related targets were retrieved by public databases, and the Venn diagram selected the overlapping targets. The networks between overlapping targets and bioactives were visualized, constructed, and analyzed by RPackage. Finally, we implemented a molecular docking test (MDT) to explore key target(s) and compound(s) on AutoDockVina and LigPlot+. GC-MS detected a total of 34 bioactives and all were accepted by Lipinski's rules and therefore classified as drug-like compounds (DLCs). A total of 597 bioactive-related targets and 4245 cancer-related targets were identified from public databases. The final 51 overlapping targets were selected between the bioactive targets network and cancer-related targets. With Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, a total of 20 signaling pathways were manifested, and a hub signaling pathway (PI3K-Akt signaling pathway), a key target (Akt1), and a key compound (Urs-12-en-24-oic acid, 3-oxo, methyl ester) were selected among the 20 signaling pathways via MDT. Overall, Urs-12-en-24-oic acid, 3-oxo, methyl ester from the C. maackii flower has potent anti-cancer efficacy by inactivating Akt1 on the PI3K-Akt signaling pathway.
