Used as a potent inhibitor of cyclin-dependent kinases (CDKs), particularly CDK2 and CDK4, making it a valuable compound in cancer research. It interferes with cell cycle progression by blocking the activity of these kinases, which are crucial for cell division and proliferation. Due to this mechanism, it has been widely employed in studies related to antitumor agents and the development of targeted cancer therapies. Its structure allows for high selectivity and binding affinity, making it a common scaffold in medicinal chemistry for optimizing kinase inhibitors. Also utilized in biochemical assays to study cell cycle regulation and apoptosis in various cancer cell lines.
