Methods: Thirty male-specific pathogen-free Sprague–Dawley rats were randomly divided into 3 groups: the blank control group, the model control group, and the LLAE group. The body weight of the rats was recorded during the treatment period. The serum, liver, and intestinal content samples were collected for further analysis after sacrificing. Results: The results suggest that LLAE-treated hyperlipidemic rats showed a significant reduction in serum triglycerides, total cholesterols, and low-density lipoprotein cholesterol levels. LLAE could improve hepatocyte steatosis and ameliorate hepatocyte injury. The significant variation in gut microbial alpha diversity at multiple levels, including phylum and genus levels occurred throughout treatment in the LLAE group. The intestinal microbiota of hyperlipidemic rats were disordered, and there was a correlation between the amount of intestinal flora and the level of lipids. Conclusion: LLAE may improve hepatocyte function by changing the type and abundance value of intestinal microorganisms, reducing the content of total cholesterol, total triglyceride, and low-density lipoprotein cholesterol, and thus improving hyperlipidemia.","PeriodicalId":509851,"journal":{"name":"Natural Product Communications","volume":"56 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141389917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to determine the volatile components of the ethyl acetate (EtOAc) fractionated extract found in the rhizomes of this species. This is the first report on the chemical composition and bioactivities of Z. monophyllum rhizomes fractionated extract. Methods: The chemical constituents were analyzed and determined using gas chromatography-mass spectrometry (GC-MS). Antioxidant activities were evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and ferric reducing antioxidant power (FRAP) assays using ascorbic acid as a positive control. Antibacterial and antifungal properties of the EtOAc fractionated extract of Z. monophyllum rhizomes were assessed against Escherichia coli, Pseudomonas aeruginosa, Salmonella enterica, Enterococcus faecalis, Staphylococcus aureus, Bacillus cereus, and Candida albicans. Density functional theory (DFT) and molecular docking were also employed to illustrate antioxidant and antimicrobial activities. Results: Nine components were identified by GC-MS analysis from the EtOAc fractionated extract of Z. monophyllum rhizomes. ( E)-labda-8(17),12-diene-15,16-dial (9), spathulenol (2), and neointermedeol (5) were the major components (21.8%, 16.8%, and 11.9%, respectively). Moderate antioxidant activities of the EtOAc fractionated extract were observed via both the DPPH assay and the FRAP assay using ascorbic acid as the standard compound. The extract demonstrated remarkable antimicrobial activity against all examined microbial strains, except for P. aeruginosa. The DFT study analyzed the antioxidant potential of each component in the fractionated extract. Molecular docking study chose E. faecalis DNA gyrase B, E. coli DNA gyrase B, S. aureus biotin protein ligase, E. faecalis Alanine racemase, and C. albicans N-myristoyltransferase as potential target proteins for antimicrobial activity. Conclusion: In this study, the chemical composition of the EtOAc fractionated extract of Z monophyllum rhizomes was demonstrated through GC-MS analysis for the first time. Nine components, including alloaromadendrene, spathulenol, globulol, τ-cadinol, neointermedeol, aromadendrene oxide-(2), ambrial, (E)-15,16-dinorlabda-8(17),11-dien-13-one, and (E)-lambda-8 (17),12-diene-15,16-dial along with relative content were identified in this fractionated extract. The bioassays revealed that the fractionated extract showed moderate antioxidant activities and significant antimicrobial activities.

In order to induce arthritis in the Sprague-Dawley rats, CFA vaccination was used, and Eupatilin was given to the rats at dose of 5, 10, and 20 mg/kg. Various biochemical and other parameters were studied to define the pharmacological benefit of Eupatilin. The study's findings revealed that Eupatilin increases rats’ body weight and significantly reduces hind paw volume. It also improves the antioxidant status of CFA rats by lowering malondialdehyde levels and increasing the concentration of endogenous antioxidants superoxide dismutase and GPx. Eupatilin also improved hematological markers, which were demonstrated to be altered in CFA rats as compared to the control. In the Eupatilin-treated group, the level of pro-inflammatory cytokines was found to be reduced as compared to CFA rats. In a molecular docking analysis, it showed favorable interaction with the active site of cyclooxygenase-2 (COX-2) by the formation of numerous nonbonded interactions by interacting with Cys32, Leu138, Pro 139, Val141, Ala142, and Cys145. It also showed a Vina score of −9.4 and interacts with the cavity volume of 4435 Å3. Eupatilin showed favorable antiarthritic benefits in the CFA-induced arthritis model, as evidenced by reductions in paw volume, significant weight loss prevention, and maintenance of the healthy hematological and biochemical profile may be through inhibiting COX-2.","PeriodicalId":509851,"journal":{"name":"Natural Product Communications","volume":"4 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141029512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dihydromyricetin (DMY) is commonly used as a hepatoprotective agent owing to its remarkable efficacy in treating chronic alcoholic liver injury; however, its mechanism of action is unclear. The object of the study is to investigate the effect and mechanism of DMY in alleviating chronic ALD. A mouse model of chronic ALD was established. Mice were treated with DMY for 56 days, and their biochemical parameters including liver function, blood lipids, and oxidative stress-related indices were measured. Farnesoid X receptor (FXR) expression, NOD-like receptor protein 3 (NLRP3) pathway-related protein expression, and inflammation-related gene expression were determined to elucidate the mechanism of DMY in mice with ALD. Lastly, serum and liver metabolomics-based UHPLC-Orbitrap Exploris MS analyses were used to determine the influence of the metabolism of DMY on mice with ALD. Pharmacodynamic studies showed that DMY could decrease aspartate transaminase, alanine transaminase, triglyceride, and low-density lipoprotein cholesterol levels, improve superoxide dismutase activity, and reduce inflammation in mice with ALD. DMY treatment protects the liver by increasing FXR protein expression and by decreasing NLRP3 pathway-related protein expression and inflammatory gene expression. Metabolomics analysis indicated that ethanol treatment mainly altered metabolism in mice. DMY could regulate 10 metabolites in serum, namely, N-α-acetyllysine, 1-pyrrolinecytosine, glutamyllysine, 5-methylcytosine, N-methylvaline, pyridoxamine, demethoxycurcumin, L-arginine, triacetin, and 15-methylpalmitate. It could also regulate 31 metabolites in the liver, including L-methionine and L-leucine. DMY treatment altered the following important pathways: valine, leucine, and isoleucine biosynthesis; cysteine and methionine metabolism; and valine, leucine, and isoleucine degradation. Correlation analyses using heatmaps revealed that the metabolic parameters are closely related to the pharmacodynamic index. These findings indicated that DMY alleviated ALD by regulating the FXR-NLRP3 signaling pathway and could treat serum and liver metabolic disorders.","PeriodicalId":509851,"journal":{"name":"Natural Product Communications","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141044326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lycium ruthenicum Murray is a renowned edible plant, the fruit of which is abundant in anthocyanins and exhibits many biological activities. This study aimed to investigate the potential impact of anthocyanins derived from Lycium ruthenicum Murray (ACN) intervention on improving obesity by regulating the gut microbiota and bile acids (BAs) metabolism in high-fat diet (HFD)-induced female mice. A total of 32 C57BL/6J female mice were divided into four distinct groups: the Ctrl group (fed a normal diet), Ctrl + ACN group (fed a normal diet plus 8 mg/mL extract of ACN), HFD group (fed a high-fat diet), and HFD + ACN group (fed a HFD plus 8 mg/mL extract of ACN). The findings showed that ACN significantly reduced the body weight, periovarian adipose mass, and adipocyte diameter, ameliorated lipid accumulation in the liver, and lowered the serum total cholesterol and low-density lipoprotein (LDL-C) levels in HFD-induced female mice. In addition, ACN exhibited a reversal of gut microbial dysbiosis in HFD-fed female mice, such as by enhancing the quantity of Lactobacillus and Allobaculum and reducing the abundance of Blautia and Faecalibaculum. Moreover, the results of fecal BAs showed that ACN led to a decrease in the ratio of primary to secondary BAs, mainly attributed to decreased levels of primary BAs, including CA, CDCA, αMCA, and HCA in HFD-induced female mice. Further analysis revealed that ACN may exert its anti-obesity effect by increasing the relative abundance of Lactobacillus_ jonsonii and Lactobacillus_reuteri within the gut and subsequently affecting the metabolism of fecal HDCA and GUDCA. These results indicated that ACN effectively inhibits HFD-induced obesity in female mice by regulating gut microbiota-related BA metabolism.","PeriodicalId":509851,"journal":{"name":"Natural Product Communications","volume":"74 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140792230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
