Used as a potent inhibitor in biochemical research, particularly targeting cyclin-dependent kinases (CDKs), which play key roles in cell cycle regulation. It is employed in studies related to cancer and neurodegenerative diseases due to its ability to modulate kinase activity. Commonly applied in in vitro assays to investigate signal transduction pathways and to evaluate potential therapeutic agents. Its selectivity and potency make it suitable for structure-activity relationship (SAR) studies in drug discovery programs focused on developing anti-cancer compounds.
