摘要：
A novel tungstosilicic polyoxometalate containing 5-fluorouracil and Nd, K26(C4H4FN2O2)8Nd(SiW11O39)4·5H2O (FNSW) was synthesized and its structure was characterized by using elemental analysis, FT-IR spectra, X-ray powder diffraction, UV-vis spectra and TG. The results indicated that the compound FNSW had Keggin structure of heteropolyanion and ring structure of 5-fluorouracil, and it had a good thermal stability. With 5-fluorouracil for the positive control group, the cytotoxicity tests in human renal embryonic cell HEK293 and the antitumor activity tests in hepatocellular carcinoma cell HepG-2 were carried out by the methyl thiazolyl tetrazolium method. The toxicity of the compound FNSW was lower than that of 5-fluorouracil, and compared with 5-fluorouracil the compound FNSW could inhibit HepG-2 cell in vitro with significant difference. The rare earth element Nd increased the biological activity of polyoxometalate significantly.
