[The biological effects of coordination compounds of transitional metals. 6. Effect of 4-methyl-2-aminopyridine-palladium chloride and cis-dichlorodiammine-platinum(II) on retroviruses and the virus-associated RNA polymerase of the influenza virus].
The effect on retroviruses of two transition metal complexes of known antiviral activity, 4-methyl-2-amino-pyridine-palladium-chloride (MAP) and cis-dichloro-diammine-platinum(II) (cis-DDP) has been investigated. The experiments included the evaluation of the action of compounds on virus particle-associated reverse transcriptase in exogenous assays, on virus propagation in persistently infected cell cultures and on virus infectivity in mice. In disrupted viruses and in the absence of excess protein, the reverse transcriptase was inhibited by MAP but not by cis-DDP. The same results were obtained when examining the activity of the virus-associated RNA polymerase of influenza virus A/WSN. Both compounds did not inhibit the replication of retroviruses in cell cultures, except at high dose levels which exerted toxic action on both cells and virus formation. The leukemogenicity of Rauscher murine leukemia virus was strongly inhibited when the virus had been incubated with MAP before inoculation. A similar treatment with cis-DDP did not influence viral leukemogenicity. Despite somewhat different results with both compounds tested, we conclude from the present results that the above mentioned compounds cannot be considered as antiretroviral drugs.
