Abstract

Objective: To screen potential anti-inflammatory small molecules from Miao medicine Semiliquidambar cathayesis by molecular docking. Methods: Chemical components of Semiliquidambar cathayesis were screened from literature databases. Inflammatory-related targets were obtained by searching "inflammation" in the Genecards database. For the top 20 targets ranked by "Relevance score", target-ligand complex structures were retrieved from the Uniprot and PDB databases for molecular docking. Results: A total of 98 active components of Semiliquidambar cathayesis and 13,654 inflammation-related genes were obtained. Ten targets with high "Relevance score" and available target-ligand complex structures were screened, including MIF, TNF, SYK, TLR4, IL18, PTGS2, IL17A, IL1β, CXCL8, and NLRP3. Chemical components of Semiliquidambar cathayesis such as quercetin, catechin, isomyricitrin, and eleutheroside showed strong binding affinity to the targets, with docking scores better than -5 kcal/mol. Conclusion: Chemical components such as quercetin, catechin, isomyricitrin, and eleutheroside are potential active anti-inflammatory components of Semiliquidambar cathayesis. Further research will help clarify the material basis and action mechanism of its anti-inflammatory effect.
