Abstract: In order to find antitumor compounds, fifteen dipeptide phosphonate derivatives(Ⅲa-Ⅲo) were designed and synthesized based on the phosphonate derivatives containing one amino acid fragment. Their antitumor activities in vitro were evaluated by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. The results show that the compounds inhibit the proliferation of the tumor cells. Among the active compounds, compound Ⅲf has better inhibition effect on A-549 (human lung cancer cells) and EC-109 (human esophageal cancer cells) growth with the half maximal inhibitory concentration (IC50) values of (6.9±1.2) and (6.3±1.0) μmol/L, respectively, and compound Ⅲn shows more potent antitumor activities against SGC-7901(human gastric cancer cells) and EC-109 with the IC50 values of (6.7±1.0) and (6.1±1.0) μmol/L, respectively, close to that of cisplatin.
