Used in research as a potent and selective inhibitor of cyclin-dependent kinases (CDKs), particularly CDK2 and CDK9, which are involved in cell cycle regulation and transcription. Shows potential in oncology for disrupting cancer cell proliferation and inducing apoptosis. Also investigated for antiviral applications due to its role in modulating host cell transcription. Commonly employed in biochemical assays to study kinase signaling pathways and as a lead compound in drug development.
