Flos populi (Male Inflorescence of Populus tomentosa Carrière) Aqueous Extract Suppresses Salmonella Pullorum Infection by Affecting T3SS-1. Pathogens 2023; 12:790.

Abstract
Pullorum disease, caused by Salmonella Pullorum (S. Pullorum), is one of the most serious infectious diseases in the poultry industry. Flos populi is traditionally used in Eastern Asian countries to treat various intestinal diseases. However, the anti-infection mechanism of Flos populi is not very clear. In this study, we evaluated the anti-infective effects on S. Pullorum of Flos populi aqueous extract (FPAE) in chickens. FPAE significantly reduced S. Pullorum growth in vitro. At the cellular level, FPAE reduced S. Pullorum adhesion and invasion on DF-1 cells but did not affect its intracellular survival or replication in macrophages. Further investigation revealed that FPAE inhibited the transcription of T3SS-1 genes, which is the main virulence factor that mediates S. Pullorum adhesion and invasion in host cells. The results suggest that the anti-infective effect of FPAE likely occurs through the inhibition of S. Pullorum T3SS-1, thereby impairing its ability to adhere to and invade cells. Further, we evaluated its therapeutic effect on animal models (Jianghan domestic chickens) and found that FPAE reduced the bacterial loads in organs and decreased the mortality and weight loss of infected chickens. Our findings provide novel insights into the potential development of FPAE against S. Pullorum as an effective anti-virulence therapeutic substitute for antibiotics.

JOURNAL OF ANALYTICAL METHODS IN CHEMISTRY 2022; 2022:8026410. [PMID: 36385774 PMCID: PMC9652072 DOI: 10.1155/2022/8026410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Revised: 05/18/2022] [Accepted: 07/09/2022] [Indexed: 06/16/2023]
Abstract
Dendrobium officinale (D. officinale) is a valuable traditional Chinese herbal medicine with high commercial value. In Chinese Pharmacopoeia (Ch.P., 2020 edition), the quality of D. officinale is mainly evaluated by its polysaccharide content. However, varying growth and production conditions, such as cultivation environment, origin, harvesting process, or processing methods, resulting in highly variable yields, quality, and composition. The aim of this study was to investigate whether the content of secondary metabolites in D. officinale from different origins is consistent with the polysaccharide content. The results showed that the polysaccharide content and pass rate were ranked as GX > AH > GZ > YN. Based on the nontargeted metabolomics approach, we searched for differential components in 22 different regions of D. officinale, including amides, bibenzyls, disaccharide, flavonoids, organic nitrogenous compounds, and phenolic glycosides. The overall expression was opposite to the polysaccharide, and the most expressed was YN, followed by GZ, AH, and GX. These results indicated that the current quality standard for evaluating the quality of D. officinale by polysaccharide content alone is imperfect, and small molecule compounds need to be included as quality markers.

Abstract
Phytochemical investigation of the seeds of Capsella bursa-pastoris led to the isolation of four organosulfur compounds. There were two new compounds, 10-methylsulfinyl-decanamide (1) and 11-methylsulfinyl-undecanamide (2), along with two known compounds (3 - 4), which all have a sulfoxide group and an amide or a nitrile group. Their chemical structures were elucidated by analysing UV, IR, ESI-MS and NMR spectroscopy. In addition, compounds 1 - 4 were evaluated for their anti-inflammatory activities by using LPS-induced RAW 264.7 cells. Compounds 1 - 4 exhibited potential anti-inflammatory activities on NO release characterised by decreasing the mRNA expression levels of inducible NO synthase (iNOS), cytokines cyclooxygenase-2 (COX-2) and interleukin 6 (IL-6).

Abstract
As one of raw materials, the rhizome of Imperata cylindrica var. major (Nees) C.E. Hubb. is used in kinds of preparations curing inflammation related diseases, while its effective substances are not yet clear. In this paper, its chemical constituents and their anti-inflammatory activities were investigated. As results, ten compounds, named as imperphenoside A (1), imperphenols B (2) and C (3), imperphenosides D-F (4-6), and imperlignanosides A-D (7-10), along with previously reported thirty-seven known ones (11-47) were obtained from it. Their structures were ascertained basing on the extensive spectroscopic methods and electronic circular dichroism data analysis. Meanwhile, compounds 4, 11, 12, 24, 27, 31, 32, 37, 43, 45, and 47 exhibited nitric oxide inhibitory effects in concentration dependent at 3, 10, and 30 μM on lipopolysaccharides induced RAW 264.7 cells. Moreover, the western blot analysis indicated that compounds 4, 11, 43, and 47 could restrain the phosphorylation of nuclear factor kappa-B kinase to down-regulate the protein expression of inflammatory cytokines such as inducible nitric oxide synthase, interleukin-6 and tumor necrosis factor-α. In conclusion, they might play the anti-inflammatory effects through regulating NF-κB signaling pathway.

Enhancement of growth, antioxidative status, nonspecific immunity, and disease resistance in gibel carp (Carassius auratus) in response to dietary Flos populi extract. FISH PHYSIOLOGY AND BIOCHEMISTRY 2022; 48:67-83.

Abstract
This study investigated the effects of dietary Flos populi extract (FPE) on the growth, antioxidation capability, innate immune response, and disease resistance in gibel carp. A total of 480 fish were fed with five different diets containing 0, 0.5, 1.0, 1.5, or 2.0 g kg-1 FPE (designated as control, D0.5, D1.0, D1.5, or D2.0 groups) for 45 days. The fish were challenged with A. hydrophila after the feeding trial. Compared with the control, the feed efficiency (FE), weight gain (WG), final body weight (FBW), and specific growth rate (SGR) were significantly improved in groups D1.0 and D1.5. Dietary FPE significantly increased serum superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) activities, as well as glutathione (GSH) content. The contents of protein carbonyl (PCC) and malondialdehyde (MDA) in serum decreased significantly. Additionally, FPE supplementation in diets resulted in significant improvement in serum lysozyme (LZM) and myeloperoxidase (MPO) activities, as well as immunoglobulin M (IgM) and complement 3 (C3) concentrations. The hepatic antioxidant enzymes (CAT and SOD) activities increased, whereas content of MDA decreased in fish treated with dietary FPE than those of control both pre- and post-challenged. After 12 h-challenge, an obvious downregulation of hepatic Kelch-like-ECH-associated protein 1 (Keap1), splenic tumor necrosis factor-α (TNF-α), interleukin (IL)-8, IL-1β, and toll-like receptor 2 (TLR2) mRNA levels was observed in fish treated with dietary FPE, whereas hepatic Nrf2 transcription level was upregulated compared to the control. Furthermore, compared to group D0.5, higher relative percent survival (RPS) was observed in gibel carp fed dietary 1.0-2.0 g/kg FPE. Our results reveal that FPE supplemented diet has a stimulatory effect on antioxidant capacity and nonspecific immune response, along with improved growth performance and enhanced resistance against A. hydrophila infection in juvenile gibel carp.

Abstract
Two pairs of novel pentacyclic spermidine alkaloid enantiomers, (±)-orychoviolines A and B ((±)-1 and (±)-2), were isolated from the seeds of Orychophragmus violaceus and represented the first example of a 2-piperidinone-fused hydrodibenzofuran skeleton, constructed from a 6/5/6/6 tetracyclic system and an 18 atomic ring. The most unexpected novelty was the formation of one more piperidinone ring by a connection between C-6 and N-7. Their structures and absolute configurations were determined by spectroscopic analyses, X-ray crystallography, and ECD analysis. Compared to Ex-RAD (sodium salt of 4-carboxystyryl-4-chlorobenzylsulfone), (-)-1 exhibited a significant radioprotective effect on cell survival and DNA damage. (-)-1 also exhibited remarkable anti-inflammatory activity by inhibiting the production of NO in RAW 264.7 cells activated by lipopolysaccharide with an IC50 value of 20.3 ± 1.58 μM, which was equivalent to that of dexamethasone.
