A series of chrysin salicylate derivatives as potential antitumour agents were synthesised and evaluated their antitumour activities in vitro and in vivo. Most of the compounds exhibited moderate to good activities against MCF-7 cells, HepG2 cells, MGC-803cells and MFC cells. Among them, compound 3f showed the most potent activity against MGC-803 cells and MFC cells with IC50 values of 23.83 ± 3.68 and 27.34 ± 5.21 μM, respectively. The flow cytometry assay reconfirmed that compound 3f promoted the occurrence of tumour cells’ G1/S block under the inhibiting effect of compound 3f. Compound 3f possessed higher antitumour efficacy in tumour-bearing mice, compared with the positive control 5-Fu and the blank control saline.
