Abstract: Transition} metal-substituted mixed-valence rare earth borotungsto-heteropoly blues, Ln2H3[BW9W2Co(H2O)O39]·nH2O(Ln=La, Ce, Pr, Nd, Sm, Eu, Gd), were prepared and characterized by IR, UV, CV, TG-DTA, XPS and electrochemistry. The cell toxicity and antiviral activity of these rare earth borotungstate heteropoly blues were investigated on the inhibitory effect against influenza(A/H1N1/Jingfang/1/91, A/H3N2/Jingfang/30/95, B/Hufang/1/87) in MDCK cells, and the results suggest that these complexes exhibit an significantly inhibitory activity, which are comparable with those obtained from virazole, against influenza virus infection, and no cytotoxicity is shown on normal cells. The correlation(relation) between the structure of these complexes and their anti-virus activities was also discussed.
