Some new analogues of ribonucleoside-5'-triphosphates modified in 3'-ribose position and base [CTP (3'NH2), CTP (3'NH2) (5Me), CTP (3'N3) (5 Me), RvTP (3'N3)] have been synthesized. The inhibitions of RNA-synthesis catalyzed by the influenza A viral RNA-polymerase in cell free system and by the RNA-polymerase II from mice liver in the system of cellular nuclei by these reagents have been compared. All the studied preparations efficiently inhibited the RNA-synthesis in both cases. The inhibitors modified only in 3'-ribose position did not express specificity to any of RNA-polymerases tested, while some analogues having two modification in the molecule demonstrated the selective inhibition of RNA-synthesis directed by the influenza A viral RNA-polymerase [ara GTP (3'NH2), RvTP (3'N3')].
