Abstract
Background: Recent epidemic survey data have revealed a globally increasing prevalence
of autism spectrum disorders (ASDs). Currently, while Western medicine mostly uses a
combination of comprehensive intervention and rehabilitative treatment, patient outcomes remain
unsatisfactory. Polygala-Acorus, used as a pair drug, positively affects the brain and kidneys,
and can improve intelligence, wisdom, and awareness; however, the underlying mechanism
of action is unclear.
Objectives: We performed network pharmacology analysis of the mechanism of Polygala–Acorus in treating ASD and its potential therapeutic effects to provide a scientific basis for the
pharmaceutical’s clinical application.
Methods: The chemical compositions and targets corresponding to Polygala–Acorus were obtained
using the Traditional Chinese Medicine Systematic Pharmacology Database and Analysis
Platform, Chemical Source Website, and PharmMapper database. Disease targets in ASD were
screened using the DisGeNET, DrugBank, and GeneCards databases. Gene Ontology functional
analysis and metabolic pathway analysis (Kyoto Encyclopedia of Genes and Genomes) were
performed using the Metascape database and validated via molecular docking using AutoDock
Vina and PyMOL software.
Results: Molecular docking analysis showed that the key active components of Polygala-
Acorus interacted with the following key targets: EGFR, SRC, MAPK1, and ALB. Thus, the
key active components of Polygala-Acorus (sibiricaxanthone A, sibiricaxanthone B tenuifolin,
polygalic acid, cycloartenol, and 8-isopentenyl-kaempferol) have been found to bind to EGFR,
SRC, MAPK1, and ALB.
Conclusion: This study has preliminarily revealed the active ingredients and underlying mechanism
of Polygala-Acorus in the treatment of ASD, and our predictions need to be proven by
further experimentation.

Network pharmacology, molecular docking, Polygala-Acorus, autism spectrum disorder, drugs and disease, molecular mechanism.
