Used in the synthesis of pharmaceuticals, particularly as a key intermediate in the development of kinase inhibitors for cancer treatment. It serves as a scaffold in drug design due to its structural similarity to purine bases, enabling interaction with biological targets such as enzymes and receptors. Commonly found in research for anticancer, antiviral, and anti-inflammatory agents. Also employed in the creation of selective inhibitors for protein kinases involved in signal transduction pathways. Its derivatives are explored for improved potency and selectivity in therapeutic applications.
