Synthesis of base-modified 3''-deoxyanalogs of (2''-5'')-oligoadenylates
New derivatives of natural (2'-5')-oligoadenylates included double modifications in oligomer molecule have been synthesized. The synthesized compounds contain the ribavirin fragment or BAP-riboside as 5'-terminal or central nucleoside unit and 3'-deoxyadenosine (cordicepine) fragment at the 2'-end of oligomer chain. The modified (2'-5')-oligoadenylates have been obtained by the triester method. The compounds prepared may be of interest for investigation as antiviral agents in agriculture and medicine.
