Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeted cancer therapies. It serves as a building block in the development of compounds that modulate protein kinases involved in cell signaling, proliferation, and apoptosis. Its structure mimics purine bases, allowing integration into biologically active molecules with potential activity against leukemia, melanoma, and other cancers. Also explored in the design of antiviral agents and immunomodulators due to its ability to interfere with nucleotide metabolism and signal transduction pathways.
