[Abstract]
The network pharmacological methods and molecular docking technology were used for investigating the possibility of Psoraleae Fructus in promoting precocious puberty in children and its potential mechanism. Methods The main active ingredients of Psoraleae Fructus and their therapeutic targets were obtained from BATMAN- TCM online platform. The disease targets related with precocious puberty were obtained from GeneCards database. A visualized network of active ingredients-disease targets was constructed by Cytoscape 3.7.1 software. Protein- protein interaction(PPI) network diagrams were constructed based on the STRING online database. Gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were conducted using Metascape online tool. The structures of the main active ingredients were obtained from PubChem database, the structures of core targets were obtained from RCSB PDB database, and then the structures were imported into Autodock for molecular docking. Finally, the mimic diagrams of the molecular docking were drawn using PYMOL software. Results A total of 12 active ingredients of Psoraleae Fructus were obtained, involving 274 targets. And there were 11 active ingredients and 98 targets associated with precocious puberty. The main active compounds were stigmasterol,bakuchiol,angelicin,bavachalcone,isobavachalcone, and xanthotoxin. The main targets were estrogen receptor 1(ESR1),estrogen receptor 2(ESR2),insulin-like growth factor 1(IGF1),and progesterone receptor(PGR),which were mainly involved in the ovarian steroidogenic pathway and Hippo signaling pathway. The molecular docking results showed that the active compounds were well binded to the targets. Conclusion It is possible that Psoraleae Fructus can promote the sexual development in children and has its potential pharmacological mechanism. The results will provide theoretical references for the clinical prevention and treatment of precocious puberty and early pubertal development in children
