Used as a potent and selective inhibitor of cyclin-dependent kinase 2 (CDK2), this compound plays a significant role in biochemical and pharmacological research, particularly in the study of cell cycle regulation and cancer development. It serves as a valuable tool in understanding the function of CDK2 in tumor proliferation and is often employed in early-stage drug discovery programs targeting cancers with dysregulated cell cycles. Its ability to bind effectively to the ATP-binding site of CDK2 makes it a scaffold for designing more advanced kinase inhibitors. Additionally, it is utilized in cellular assays to probe CDK2-dependent pathways and assess the impact of kinase inhibition on cell division and apoptosis.
