Used in research as a potent and selective inhibitor of cyclin-dependent kinases (CDKs), particularly CDK2 and CDK9, making it a valuable tool compound in studies related to cell cycle regulation and transcription in cancer biology. It serves as a scaffold in the development of anticancer agents due to its ability to induce cell cycle arrest and apoptosis in tumor cells. Also employed in biochemical assays to probe kinase signaling pathways and assess the therapeutic potential of CDK inhibition. Its selectivity profile supports its use in preclinical models to understand the effects of targeted kinase modulation without broad off-target activity.
