    Project supported by the National High Technology Research and Development Program of China (863 Program, No. 2013AA064102) and the Project of Science and Technology of Hunan Province (No. 2010FJ4112).

In this work, several 2,4-diaminoquinazoline and 2,4-diaminopyrido[2,3-d]pyrimidine derivatives were designed and synthesized by acylation reaction and ring-closure reaction, using 6-chloro-5-cyanonicotinic acid, 3-cyano-4-fluoroben- zoic acid, 4-cyano-3-fluorobenzoic acid and 6-chloro-5-cyanopicolinic acid as starting materials. This method is simple and efficient. For the used acids but 6-chloro-5-cyanopicolinic acid, the reaction yields are above 65%. The structures of terminational compounds were determined by 1H NMR, 13C NMR and LC-MS. The antitumor activities of the nitrogen mustard-linked chalcones were evaluated by an MTT assay. The results reveal that some of the title compounds exhibit potent anti-proliferative activities against selected tumor cells. Among which, compounds 4c, 4d, 4e and 4f against K562 and HepG2 were better than 5-fluorouracil.
