AB The anti-human immunodeficiency virus (HIV) activity of polyoxometalates
of representative structural families, such as Keggin, lacunary Keggin,
trivacant Keggin, Keggin sandwich, Wells-Dawson and Wells-Dawson
sandwich, was determined using two strains of HIV type 1 (HIV-1HTLV-IIIB
and HIV-1SF-2H). The compounds were preferably selected to cover both
polyoxotungstates and polyoxomolybdates in each structural family. In
general, polyoxotungstates of Keggin, lacunary Keggin, trivacant Keggin,
Keggin sandwich, Wells-Dawson and Wells-Dawson sandwich structures
showed anti-HIV-1HTLVIIIB activity, whereas most compounds not included
in these structural categories were inactive. Among the compounds with a
potent anti-HIV-1HTLV-IIIB activity, those of Keggin and its closely
related structural families (lacunary Keggin, trivacant Keggin and
Keggin sandwich) inhibited the cytopathogenicity and syncytium formation
caused by HIV-1SF-2 to a much higher extent compared with
HIV-1HTLV-IIIB-related ones. The difference between the spectra of
anti-HIV-1HTLV-IIIB activity and the specificity for HIV-1SF-2H might
result from differential structural requirements in these functions.
