Special Issue Information

Dear Colleagues,

Plant-derived phytochemicals have emerged as novel agents able to protect against chronic disorders. Owing to the diversity of phytochemicals, they cover a wide spectrum of therapeutic indications against cancer and inflammation-related diseases, as well as cardiovascular, rheumatoid, autoimmune, and neurological diseases, and represent an abundant source of lead compounds for the development of novel medications. Recently, efforts to understand these diseases via conventional molecular biological experiments to collect omics data have rapidly expanded. In order to determine the poly-pharmacological effects of multicomponent phytochemicals, significant time and effort is required in the form of conventional experiments. The treatment of diseases with phytochemicals through the regulation of intestinal inflammation, such as the gut–brain axis, has recently attracted significant attention. Therefore, we should aim to develop a deeper understanding of these diseases and the development of improved treatments through a more integrated approach.

An important direction for future investigation is the further optimization of integrated phytochemical analysis and network pharmacology to predict multiple targets. Combinatorial strategies that target multiple mechanisms to increase anti-inflammatory efficacy and trigger an innate immune response to control chromosome stability may offer the best solution for clinically meaningful treatment. This Special Issue aims to identify lead compounds for inflammation-related diseases through in-depth studies on the mechanisms of medicinal plant components.

This Special Issue will consider papers presenting analyses of both herbal compounds and crude materials, as long as the study considers phytochemicals. In addition to in vivo, in vitro, and in silico studies, articles utilizing clinical evidence (systematic reviews or meta-analysis) are welcome. However, when utilizing clinical data, there should be an in-depth additional analysis of the pharmacological mode of action of the natural product under study, and the authors' original views on indications should be presented. Studies that merely synthesize clinical evidence for natural products will not be considered.

So Shiho Tang (SSHT) is a traditional herbal medicine commonly used in Asian countries. This study evaluated the anti-inflammatory effect of SSHT and the associated mechanism using lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages and murine dextran sodium sulfate (DSS)-induced ulcerative colitis models. Pre-treatment of RAW 264.7 macrophages with SSHT significantly reduced LPS-induced inflammation by decreasing nitrite production and regulating the mitogen-activated protein kinase pathway. Meanwhile, in mice, DSS-induced colitis symptoms, including colon shortening and body weight loss, were attenuated by SSHT. Moreover, representative compounds of SSHT, including glycyrrhizic acid, ginsenoside Rb1, baicalin, saikosaponin A, and saikosaponin B2, were quantified, and their effects on nitrite production were measured. A potential anti-inflammatory effect was detected in LPS-induced RAW 264.7 cells. Our findings suggest that SSHT is a promising anti-inflammatory agent. Its representative components, including saikosaponin B2, ginsenoside Rb1, and baicalin, may represent the key active compounds responsible for eliciting the anti-inflammatory effects and can, therefore, serve as quality control markers in SSHT preparations.

Backgound: Pyeongwi-san (PWS) is a widely used formula for treating digestive disorders in Korea and China. Inflammatory bowel disease (IBD) is characterized by progressive inflammation of the gastrointestinal tract. Emerging evidence supports the protective effect of PWS against IBD, but specific mechanisms are still elusive. Methods: Active compounds of PWS were screened from the medicinal materials and chemical compounds in Northeast Asian traditional medicine (TM-MC) in the consideration of drug-likeness and oral bioavailability. Target candidates of active compounds were predicted using the ChEMBL database. IBD-related targets were obtained from the GeneCards and DisGeNET databases. The network of composition-targets-disease was constructed. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were analyzed. Molecular docking was used to simulate the binding affinity of active compounds on target proteins and molecular dynamics was used to validate the molecular docking result. Results: A total of 26 core target proteins of PWS were related to IBD. Enrichment analysis suggested that PWS is highly associated with tumor necrosis factor signaling pathway, apoptosis, and the collapse of tight junctions. Moreover, molecular docking and molecular dynamics simulation proposed β-eudesmol and (3R,6R,7S)-1,10-bisaboladien-3-ol to ameliorate IBD through the binding to TNF and MMP9, respectively. Conclusion: Present in silico analysis revealed potential pathways and insight of PWS to regulate IBD. These results imply that the therapeutic effect of PWS might be achieved via an inhibitory effect. Full article
