Used as a potent antiviral agent, particularly effective against certain RNA viruses by inhibiting viral replication through targeted interference with viral polymerase activity. Its structure enables high binding affinity to conserved regions of the viral enzyme, making it valuable in developing treatments for resistant strains. Commonly investigated in the context of broad-spectrum antiviral therapies, including potential application in treating emerging viral infections. Also explored for use in combination therapies to enhance efficacy and reduce the likelihood of resistance development. Due to its cell permeability and metabolic stability, it is suitable for oral formulation in clinical settings.
