| Abstract: | Dipyridamole in concentration of 25 microM inhibited the multiplication of vaccinia virus in about 90% of cells. In the presence of this substance, [3H]-uptake was sharply reduced both in uninfected and infected RK13 cells, while [14C]-uptake was not inhibited incorporation of [3H]-thymidine and [14C]-amino acids into viral particles. The present findings suggest that the antiviral character of dipyridamole is related with the inhibition of the substrate transport through the cell membrane. |
