Investigation of the metabolites of five major constituents from Berberis amurensis in normal and pseudo germ-free rats / 中国天然药物

Berberis amurensis (Berberidaceae) is a traditional Chinese medicine, which is often used to treat hypertension, inflammation, dysentery and enteritis. It contains alkaloids, mainly including berberine, berbamine, magnoflorine, jatrorrhizine and palmatine. Berberis amurensis extracts (BAEs) is often orally taken. Oral herbs might be metabolized by intestinal bacteria in the small intestine. However, the interaction between the herb and the gut microbiota is still unknown. In the current study, UPLC/Q-TOF-MS/MS combined with Metabolitepilot and Peakview software was used to identify the metabolites of BAEs in anti-biotic cocktail induced pseudo germ-free rats and normal rats. As a result, a total of 46 metabolites in normal rats were detected and its main metabolic pathways include demethylation, dehydrogenation, methylation, hydroxylation, sulfation and glucuronidation. Only 29 metabolites existed in pseudo germ-free rats. Dehydrogenated metabolites (M29, M30, M34 and M36), methylated metabolites (M33, M41 and M46) and other metabolites were not detected in pseudo germ-free rats. The result implied that the intestinal bacteria have an influence on the metabolism of BAEs. Furthermore, this investigation might contribute to the understanding of the metabolism of BAEs, and further promote its clinical application.

Targets of the 25 compounds in FYM were predicted according to the reverse pharmacophore method and TCMSP, UniProt database. Gene ontology (GO) function enrichment and pathway analysis of the targets was analyzed by Omicsbean software and the Kyoto Gene and Genome Encyclopedia (KEGG) database. A "compound-target-pathway-pharmacological action-effect" network was established with Cytoscape 3.6.1 software. The lipopolysaccharide (LPS)-induced RAW264.7 cell inflammation model was used to verify the anti-inflammatory effects of FYM and its 10 important components. The network pharmacology experiment showed that 25 compounds affected 97 pathways through 211 targets, of which 15 key targets [including RAC-alpha serine/threonine-protein kinase (AKT1), insulin (INS), vascular endothelial growth factor A (VEGFA), interleukin-6 (IL-6), cellular tumor antigen p53 (TP53), tumor necrosis factor (TNF), transcription factor AP-1 (JUN), caspase-3 (CASP3), matrix metalloproteinase-9 (MMP9), interleukin-8 (IL-8), prostaglandin G/H synthase 2 (PTGS2), proto-oncogene c-Fos (FOS), tyrosine-protein kinase SRC (SRC), c-Jun N-terminal kinase 1 (MAPK8), estrogen receptor 1 (ESR1)] and 46 pathways (including NF-kappa B signaling pathway, Toll-like receptor signaling pathway, MAPK signaling pathway, IL-17 signaling pathway, arachidonic acid metabolism, cAMP signaling pathway, T cell receptor signaling pathway, calcium signaling pathway, inflammatory mediator regulation of TRP channels, chemokine signaling pathway, Th1 and Th2 cell differentiation, natural killer cell mediated cytotoxicity, etc.) were related to anti-inflammatory, antipyretic, immune regulation, and analgesia. In vitro cell experiments showed that FYM and the 10 components (including isoquercitrin, luteoloside, baicalein, wogonin, wogonoside, phillyrin, forsythoside A, chlorogenic acid, isochlorogenic acid A, and sweroside) could significantly reduce the expression of nitric oxide (NO), TNF-α and IL-6 in cell supernatants, indicating that the above 10 components may be the key pharmacodynamic material basis of FYM.

Safety and effectiveness of hemoperfusion on the removal of uremic toxins in chronic kidney disease / 药学学报

The goal of the present study was to determine the effectiveness and safety of hemoperfusion (HP) in beagle dogs with chronic kidney disease (CKD). The experimental protocol was approved by the Institutional Animal Care and Use Committee of Tianjin Institute of Pharmaceutical Research New Drug Evaluation Research (IACUC2019071501). Twelve CKD model beagles were randomly divided into two groups: a low-frequency treatment group (n = 6) and a high-frequency treatment group (n = 6). The dogs in the high- and low-frequency groups received HP treatment every 3 days and once per week, respectively, for two treatments, with each session lasting 2 h. The test results showed that high-frequency HP treatment significantly decreased the accumulation of toxins in the CKD beagles. Hematology, coagulation function, electrolytes and liver function indicated that the HP treatment was safe. The body index effects were consistent between the low- and high-frequency treatment groups. Therefore, HP treatment once every 3 days was safe at the animal level. Multiple HP treatments every 3 days were more conducive than weekly treatments to the removal of uremic toxins with better prognosis and had no associated safety hazards.

A New Concept on Quality Marker for Quality Assessment and Process Control of Chinese Medicines / 中草药·英文版

Chinese medicine (CM) is the most typical conventional therapy compared with any other traditional or alternative medicine systems. The active components of CMs are either primary or secondary metabolites generated by metabolic and biosynthetic enzymes in plants, protecting the plants from environmental stress. The characteristics of these metabolites are diverse, complicated and unique. In this paper, current approaches for quality assessment were extensively reviewed, a new concept of quality marker (Q-marker) was then proposed for CM quality assessment. Additionally, definition of the Q-marker, as well as the relevant methods, were discussed, on the basis of the biosynthetic pathways of secondary metabolites and source of biological active components. Study design of Q-marker is complex system for quality assessment and production process control of CM products with transitivity and traceability. Therefore, the system with characteristics of transmission and traceability is expected to be established for regulation of quality. Upon the concept which the transitivity and traceability in the quality assessment and production process control covered the entire process, such as raw materials, decoction slices, processing, extraction and production can be further enhanced. The transitivity and traceability will inevitably require close attention to “who, what, where, when, and why” details at each stage of Q-markers of CM production form raw materials to patent product. The establishing quality standards are enablers of many and various transitivity and traceability solutions, not a solution in them. It means that the transitivity and traceability system is readily link between products and across borders in quality. According to the thinking mode and methods of investigation on quality assessment of CM product, we focus on the entire process, in terms of safety and effectiveness and quality control. The standard preparation of CM or CM decoction is not only the basis for study of Q-marker, but also the basis for transmission and traceability of the quality of CM product.
