Antiviral Nucleoside and Nucleotide Analogs: A Review

Abstract

Virus infections are an increasing and probably lasting global risk. Nucleoside and nucleotide analogs represent the largest class of antiviral drugs. Early success in the treatment of human immunodeficiency virus infection and the recent approval of sofosbuvir as phosphoramidate nucleoside prodrug for chronic hepatitis C have provided proof of concept for important this class of compounds as an antiviral agent. This review summarizes the antiviral activity of nucleoside and nucleotide analogs and their recent application.
