摘要
Two series of thieno[2,3-d]pyrimidine derivatives were designed and synthesized, in which bioactive α-aminophosphonate subunits were introduced at the N3 position through an N-N bond connection. The in vitro cytotoxic activity of the novel compounds was tested against human esophageal carcinoma cells （EC109）, human hepatocarcinoma cells （HepG2）, human gastric carcinoma cells （MGC-803）, respectively, by the MTT method. The evaluation results revealed that compounds fimb, 6mf, 6mg, 6rid and 6nh exerted the most potent inhibition against HepG2, MGC-803 and EC109 cells, respectively. In particular, compound 6rag presented excellent inhibitory effect against HepG2 （91.2%） and MGC-803 （94.4%） cells.
