Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting protein kinases involved in inflammatory diseases and cancer. Its structure allows for selective binding to enzyme active sites, making it valuable in developing targeted therapies. Also explored in the design of antiviral agents due to its ability to modulate cellular signaling pathways. Commonly employed in structure-activity relationship (SAR) studies to optimize drug candidates for improved potency and metabolic stability.
