Acyclic nucleotide analogue, preparation method therefor, and application thereof

The present invention relates to the technical field of chemically synthesized drugs, and in particular, to an acyclic nucleotide analogue, a preparation method therefor, and an application thereof in an antiviral drug. A technical problem to be solved by the present invention is to provide a novel acyclic nucleotide analogue, having a structure represented by formula (I). The acyclic nucleotide analogue of the present invention has an antiviral efficacy and provides a new choice for the development of antiviral drugs.
