Used in pharmaceutical research as a potent and selective inhibitor of cyclin-dependent kinases (CDKs), particularly CDK9, which plays a key role in transcription regulation. This compound shows promise in oncology for targeting cancer cells by disrupting the transcriptional machinery necessary for tumor growth and survival. It is investigated for its antiproliferative effects in hematological malignancies and solid tumors. Additionally, due to its ability to modulate kinase activity with high specificity, it serves as a valuable tool compound in signal transduction studies and target validation during drug discovery.
