Suppressive effect of polyoxometalates on the cytopathogenicity of human immunodeficiency virus type 1 (HIV-1) in vitro and their inhibitory activity against HIV-1 reverse transcriptase.

One isopolyoxometalate and 42 heteropolyoxometalates consisting of 3 compounds with the trivacant Keggin structure, 2 with the lacunary Keggin structure, 30 with the Keggin structure, one with the Wells-Dawson structure and 6 with miscellaneous structures were tested for their suppressive effect on the cytopathogenicity of human immunodeficiency virus type 1 (HIV-1) in vitro and inhibitory activity against HIV-1 reverse transcriptase. In contrast to the leading interpretations which attribute the suppressive effect of polyoxometalates on the cytopathogenicity of HIV-1 to the inhibition of HIV-1 reverse transcriptase by these compounds, there was no distinct correlation observed between these two functions of polyoxometalates.
