The antiviral effect of 2',5'-trioligoadenylate (2',5'-A(3)) and some
of its analogues was studied using several model cell culture systems
and viruses: mice L929 fibroblast cells inoculated with vaccine virus,
testicular piglet cells inoculated with Aueszki disease virus (strain
BUK-628), and the same culture inoculated with a reference strain of
transmissible.gastroenteritis virus, strain Purdue - 115. Our results
suggest that both 2',5'-trioligoadenylate and its analogues are promis
ing antiviral substances against DNA-and RNA-containing viruses.
