N-Furfurylideneanilines and N-arylamino(2-furyl)methylphosphonates with tolyl and anisyl moieties were synthesized by the addition of phosphites to azomethine bond of corresponding Schiff bases and their NMR spectroscopic properties were investigated. Then, they were analyzed in the point of view of their influence on KYSE 30, KYSE 150, and KYSE 270 esophageal cancer cell lines and on immortalized esophageal cell line HET 1 A as a control group. Toxicity was evaluated by MTT assay. Among 11 compounds, a few of them demonstrated influence on cancer cells being neutral toward the control, but only one aminophosphonate had IC50 lower than 100 mu M and acted as a potential anticancer drug. Some approaches to structure-activity relation were performed.
