Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting cancer-related enzymes. Its structure supports binding to ATP sites in proteins, making it valuable in developing anticancer agents. Also explored in the design of antiviral drugs due to its ability to mimic purine nucleotides. Commonly modified at the carboxylic acid group to enhance bioavailability and target specificity. Employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug candidates.
