Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. It plays a role in targeting cyclin-dependent kinases (CDKs), which are involved in cell cycle regulation. Due to its purine scaffold and halogen substitutions, it enhances binding affinity to ATP-binding sites in kinases, making it valuable in medicinal chemistry for designing drugs that modulate signaling pathways in tumors. Also employed in research settings to study cell proliferation and apoptosis mechanisms.
