Used in antiviral research, particularly in the development of potential treatments for RNA viruses. It acts as a prodrug, designed to enhance cellular uptake and metabolic activation, leading to the inhibition of viral RNA synthesis. The compound is investigated for its ability to deliver the active antiviral agent—5-fluorocytidine—more efficiently by masking polar groups, improving membrane permeability. Its modified structure allows for targeted activation in infected cells, potentially reducing off-target effects and increasing therapeutic efficacy. Currently explored in preclinical studies for broad-spectrum antiviral applications.
