The ionization and time-of-flight techniques employed in MALDI-TOF-MS, driven by laser resolution, yield a superior analytical outcome. The monosaccharides' composition and proportion were determined using the PMP-HPLC method. Cyclophosphamide-induced immunosuppression in mice was used to compare the immunomodulatory effects and mechanisms of Polygonatum steaming times. Body weight and immune organ indices were examined; ELISA analyses determined serum levels of interleukin-2 (IL-2), interferon (IFN-), immunoglobulin M (IgM), and immunoglobulin A (IgA). Finally, T-lymphocyte subsets were identified through flow cytometry to quantify the immunomodulatory differences in Polygonatum polysaccharides according to the various steaming times used in preparation. Nevirapine cell line The Illumina MiSeq high-throughput sequencing platform was utilized to investigate the effects of different steaming times of Polygonatum polysaccharides on immune function and intestinal flora, as well as to analyze short-chain fatty acids, in immunosuppressed mice.
A considerable modification to the Polygonatum polysaccharide's structure was evident as steaming times varied, marked by a substantial decline in its relative molecular weight. Interestingly, the monosaccharide profile of Polygonatum cyrtonema Hua displayed unchanging composition, despite showing alterations in content with diverse steaming durations. Concocting Polygonatum polysaccharide elevated its immunomodulatory activity, substantially increasing both spleen and thymus indices, and boosting the expression levels of IL-2, IFN-, IgA, and IgM. The immune function, as reflected by the CD4+/CD8+ ratio, of Polygonatum polysaccharide, showed a progressive increase depending on the steaming duration, showcasing a significant immunomodulatory effect. Nevirapine cell line The fecal short-chain fatty acid content in mice subjected to both six-steamed and six-sun-dried Polygonatum polysaccharides (SYWPP) and nine-steamed and nine-sun-dried Polygonatum polysaccharides (NYWPP) groups demonstrated a considerable rise, including propionic acid, isobutyric acid, valeric acid, and isovaleric acid. This enhancement positively impacted microbial community abundance and diversity. SYWPP and NYWPP augmented the relative abundance of Bacteroides and the Bacteroides-to-Firmicutes (BF) ratio. Furthermore, SYWPP notably increased the abundance of Bacteroides, Alistipes, and norank_f_Lachnospiraceae, whereas the effects of raw Polygonatum polysaccharides (RPP) and NYWPP were less pronounced compared to SYWPP.
The immune response of the organism can be significantly improved by both SYWPP and NYWPP, along with correcting the imbalance of intestinal flora in immunosuppressed mice and increasing intestinal short-chain fatty acid (SCFA) content; however, SYWPP demonstrates superior effectiveness in enhancing the organism's immune function. These discoveries on the Polygonatum cyrtonema Hua concoction process stages can help determine the optimal conditions for maximum efficacy, establish a foundation for developing quality standards, and facilitate the use of novel therapeutic agents and health foods made from Polygonatum polysaccharide, which differs by raw or steaming time.
The immune system of organisms can be significantly improved by both SYWPP and NYWPP, along with addressing the imbalances in intestinal flora in immunocompromised mice, and increasing levels of beneficial short-chain fatty acids (SCFAs); however, the impact of SYWPP on enhancing the organism's immune response is more notable. These findings investigate the optimal stages of Polygonatum cyrtonema Hua concoction, thus establishing a reference point for quality standards, and encouraging the application of novel therapeutic agents and health foods derived from Polygonatum polysaccharide, using raw and differently steamed materials.

The rhizome and root of Salvia miltiorrhiza (Danshen) and the rhizome of Ligusticum chuanxiong (Chuanxiong), are both vital traditional Chinese medicines that help activate blood and eliminate stagnation. For more than six hundred years, practitioners in China have relied upon the medicinal synergy of Danshen and Chuanxiong herbs. In the preparation of Guanxinning injection (GXN), a refined Chinese clinical prescription, aqueous extracts of Danshen and Chuanxiong are combined in a ratio of 11:1 (weight-to-weight). GXN has been utilized in clinical practice for the management of angina, heart failure, and chronic kidney disease in China for nearly two decades.
The research question of this study revolved around the contribution of GXN to renal fibrosis in mice with heart failure, with a particular focus on its effect on the SLC7A11/GPX4 axis.
A model of transverse aortic constriction was used to represent heart failure in conjunction with a kidney fibrosis model. GXN was injected into the tail vein at doses of 120, 60, and 30 mL per kilogram, respectively. To serve as a positive control, telmisartan was administered by gavage at a dosage of 61 mg per kilogram. Evaluating and contrasting cardiac ultrasound indices like ejection fraction (EF), cardiac output (CO), left ventricular volume (LV Vol), pro-B-type natriuretic peptide (Pro-BNP), serum creatinine (Scr), collagen volume fraction (CVF), and connective tissue growth factor (CTGF) provided insights into the interplay between cardiac and kidney function. The kidneys' endogenous metabolite profile was examined through the application of metabolomic methods. The kidney samples were analyzed for the presence and amounts of catalase (CAT), xanthine oxidase (XOD), nitric oxide synthase (NOS), glutathione peroxidase 4 (GPX4), x(c)(-) cysteine/glutamate antiporter (SLC7A11), and ferritin heavy chain (FTH1), employing quantitative techniques. To determine the chemical composition of GXN, ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was employed. Simultaneously, network pharmacology was used to predict potential mechanisms and active ingredients.
GXN-treated model mice exhibited varying degrees of improvement in cardiac function indices (EF, CO, LV Vol) and kidney functional markers (Scr, CVF, CTGF), and a subsequent reduction in kidney fibrosis. Redox regulation, energy metabolism, organic acid metabolism, and nucleotide metabolism were each found to be influenced by 21 distinct metabolites. The core redox metabolic pathways, encompassing aspartic acid, homocysteine, glycine, serine, methionine, purine, phenylalanine, and tyrosine metabolism, were shown to be regulated by GXN. GXN exhibited a noticeable impact on CAT content, marked by an enhancement of GPX4, SLC7A11, and FTH1 expression levels within the kidney. GXN's positive effects were not confined to other areas; it also notably decreased the levels of XOD and NOS within the kidney. Besides this, an initial survey of GXN materials revealed the presence of 35 chemical constituents. To determine the core components of the GXN-related enzymes/transporters/metabolites network, active ingredients were identified. GPX4 emerged as a crucial protein for GXN activity. The top 10 active ingredients demonstrably exhibiting renal protective effects in GXN are: rosmarinic acid, caffeic acid, ferulic acid, senkyunolide E, protocatechualdehyde, protocatechuic acid, danshensu, L-Ile, vanillic acid, and salvianolic acid A.
Significant cardiac function preservation and retardation of renal fibrosis progression were observed in HF mice treated with GXN. The mechanism of action is rooted in the regulation of redox metabolism, particularly in aspartate, glycine, serine, and cystine metabolism and the related SLC7A11/GPX4 pathway within the kidney. Nevirapine cell line Among the potential mechanisms for GXN's cardio-renal protective action is the contribution of several compounds, such as rosmarinic acid, caffeic acid, ferulic acid, senkyunolide E, protocatechualdehyde, protocatechuic acid, danshensu, L-Ile, vanillic acid, salvianolic acid A, and more.
The cardiac function of HF mice was remarkably maintained and renal fibrosis was mitigated by GXN, acting through the regulation of redox metabolism of aspartate, glycine, serine, and cystine, alongside the SLC7A11/GPX4 axis in the kidney. The cardio-renal protective effects of GXN might be due to the synergistic action of multiple components, including rosmarinic acid, caffeic acid, ferulic acid, senkyunolide E, protocatechualdehyde, protocatechuic acid, danshensu, L-Ile, vanillic acid, salvianolic acid A, and other compounds.

In ethnomedical traditions throughout Southeast Asia, Sauropus androgynus is a medicinal shrub employed to treat fever.
The purpose of this research was to isolate antiviral agents from S. androgynus against the Chikungunya virus (CHIKV), a major re-emergent mosquito-borne pathogen, and to determine the mechanisms of their antiviral action.
A hydroalcoholic extract of S. androgynus leaves was tested for anti-CHIKV activity, using a method based on cytopathic effect (CPE) reduction. Following activity-directed isolation, the extract yielded a pure molecule, which was then investigated using GC-MS, Co-GC, and Co-HPTLC. Further investigation into the isolated molecule's effect involved the use of plaque reduction, Western blot, and immunofluorescence assays. CHIKV envelope proteins were subjected to in silico docking simulations, complemented by molecular dynamics (MD) analyses, to ascertain their potential mechanism of action.
The hydroalcoholic extract of *S. androgynus* exhibited encouraging anti-CHIKV activity, and its active constituent, ethyl palmitate, a fatty acid ester, was identified by activity-directed isolation. EP, at a concentration of 1 gram per milliliter, effectively inhibited CPE by 100% and demonstrated a significant three-log decrease.
At 48 hours post-infection, Vero cells displayed a lower CHIKV replication rate. EP's exceptionally high potency was reflected in its EC.
At a concentration of 0.00019 g/mL (0.00068 M), the material displays exceptionally high selectivity. The EP treatment regimen significantly lowered viral protein expression levels, and time-course studies underscored its activity specifically at the stage of viral entry.
