Abstract
The present disclosure provides nucleoside analogs of Formula (I) or (II). The nucleoside analogs are expected to show multiple tautomerism and may increase the mutation of an RNA and/or DNA (be mutagenic) of a virus or cancer cell. The multiple tautomerism and mutagenesis of the nucleoside analogs may be adjusted by substituting the nucleoside analogs with one or more electron-donating groups and/or electron-withdrawing groups to increase or decrease the pK(e.g., to a pKbetween 5.5 or 8.5). The present disclosure also provides pharmaceutical compositions and kits including the nucleoside analogs and methods of treating a viral infection (e.g., influenza, HIV infection, or hepatitis) or cancer using the nucleoside analogs, pharmaceutical compositions, or kits.
