- Abstract: Aim To study the mechanism of the ethanol extract from Leucopaxillus giganteus (LGEE) in treating breast cancer based on network pharmacology and molecular experimental validation. Methods Some chromatographic methods were used to isolate the chemical constituents of LGEE, and their structures were elucidated based on spectral data. The antitumor activities of LGEE were determined by MTT assay. The predicted targets of LGEE were selected by TCMSP and Pharmmaper, and Genecards database was used to screen the targets. GO and KEGG analysis of target genes were performed. Molecular docking was used to test the binding of active components to core targets. Western blotting was used to validate the regulating function of chlorogenic acid on CHEK2 and CASP3 targets of MDA-MB-231 cells. Results Thirteen compounds were identified including clitocine, chlorogenic acid and so on. LGEE displayed anticancer activities against MDA-MB-231 with the inhibition percent (87. 35 ± 1. 55)%, at the concentration of 200 mg· L
