Induced intra- and intermolecular template switching as a therapeutic mechanism against RNA viruses

ABSTRACT: RNAseq experiments of Enterovirus A71 wild type demonstrate that the pyrazine-carboxamide ribonucleotide stimulates catalyzed intra- and intermolecular template switching. These results suggest that pyrazine-2 carboxamide ribonucleotides do not induce lethal mutagenesis or chain termination, but function by promoting template switching and formation of defective viral genomes. We conclude that RdRp-catalyzed intra- and intermolecular template switching can be induced by pyrazine-carboxamide ribonucleotides, defining an additional mechanistic class of antiviral ribonucleotides with potential for broad-spectrum activity.
