Abstract: The antitumor activity of 5-fluorouracil-1-acetic acid(HFAA) and its lanthanide complexes(La(FAA)3, Eu(FAA)3) were studied. The results show that HFAA, La(FAA)3 and Eu(FAA)3 with the concentrations of 1.0×10-5～1.0×10-2 μg·ml-1 inhibit the colony formation of leukemia cells(L1210) and the growth of transplanted tumor sarcoma 180(S180), hepatic carcinoma(HEPA) and ehrlich ascites tumor(EC) as well. The maximum inhibitory rate of Eu(FAA)3 for S180 is 38.4%, that HFAA and La(FAA)3 for EC are 22.4% and 43.4%, respectively. The life prolongation rate of Eu(FAA)3 for HEPA bearing mice is as long as 284%.
