Gastric cancer is one of the common malignant tumors. It is reported that daphne-type diterpenes have inhibitory effects on gastric cancer cells, but the mechanism is still unknown. To explore the detailed mechanism of the anticancer effect of daphne-type diterpenes, we carried out an integrated network pharmacology prediction study and selected an effective component (yuanhuacine, YHC) for the following validation in silico and in vitro. The result showed that daphne-type diterpenes exerted an anti-tumor effect by targeting proto-oncogene tyrosine-protein kinase SRC as well as regulating the Ras/MAPK signaling pathway, which caused the apoptosis and mitochondrial damage in gastric cancer cells.
