[Comparative antiviral and interferonogenic activity of synthetic polyribonucleotide complexes of poly(I).poly(C) and poly(G).poly(C) in different cell systems].
The antiviral and interferon-inducing activity of synthetic polyribonucleotide complexes poly(I)-poly(C) and poly(G)-poly(C) was studied in chick embryo, mouse embryo and rabbit kidney cell cultures. In chick embryo cell cultures both polyribonucleotides had similar antiviral activities. The interferon-inducing activity was more marked in poly(G)-poly(C) than in poly(I)-poly(C). In the other two cell cultures poly(I)-poly(C) was considerably superior in both activities. The revealed differences in the comparative activity of the polyribonucleotides in relation to the kind of tissue culture were not associated with differences between them in toxicity, sensitivity to pancreatic RN-ase or with possible differences in the duration of the contact with cells necessary for the achievement of the antiviral effect.
