Objective: To explore the active compounds of Maxingyigan Decoction for the treatment of coronavirus disease 2019 (COVID-19) Method(s): The chemical constituents and action targets of Ephedra sinica, Armeniacae Semen Amarum, Coicis Semen, and Glycyrrhizae Radix et Rhizoma in Maxingyigan Decoction were retrieved from TCMSP The database of UniProt and GeneCards were used to query the target genes that corresponding to the active compounds, and then a compound-target (gene) network was constructed by Cytoscape 3 6 1 GO functional enrichment analysis and KEGG enrichment analysis were performed through WebGestalt database to predict its mechanism of action The main active ingredients were docked with SARS-CoV-2 3CL hydrolase and angiotensin converting enzyme II (ACE2) Result(s): The compound-target network contained 126 compounds and 266 corresponding targets The key targets genes included PTGS2, ESR1, PCP4, PPARG, HSP90AA1, NCOA2, etc GO function enrichment analysis found that 522 GO items were affected by Maxingyigan Decoction, including 12 biological process items, 20 cell composition items, and 17 molecular function items KEGG enrichment analysis showed that 168 signal pathways were enriched, involving interferon-gamma signaling pathway, MAP kinase cascade, T cell activation, chemokines and cytokine signaling pathway-mediated inflammation pathways, etc The molecular docking results showed that core compounds such as luteolin and quercetin had similar affinity with the recommended drugs used to treat COVID-19 Conclusion(s): The active compounds in Maxingyigan Decoction may have a therapeutic effect on COVID-19 through binding with 3CL hydrolase and ACE2 to act on targets such as PTGS2, ESR1, PCP4, PPARG, HSP90AA1 and NCOA2 so as to regulate multiple signal pathways Copyright © 2020, Editorial Office of Chinese Traditional and Herbal Drugs All right reserved
