[Effect of rimantadine on the synthesis of virus-specific RNA in the culture of cells infected with Sindbis virus].

Effect of rimanthadine (alpha-methyl-I-adamantane methylamine) on the synthesis of virus specific RNA was studied in culture of cells, infected with Syndbis virus. Rimanthadine inhibits the synthesis of virus specific RNA beginning from the 3-rd hr of infection. A magnitude of inhibition from the 3-rd to the 7-th hrs of infection was practically the same and exceeded 50%. In the presence of rimanthadine "early" RNA was formed (with sedimentation constant of 20-14 S), where radioactivity was lowered as compared with control; formation of more "late" RNA peaks (43 S, 34 S and 26 S) was completely prevented within these periods of infection.
