Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for strong binding to ATP sites in protein kinases, making it valuable in targeting signaling pathways involved in tumor growth. Commonly employed in medicinal chemistry for optimizing lead compounds in drug discovery programs focused on oncology. Also utilized in the design of selective inhibitors for inflammatory and neurodegenerative diseases due to its ability to cross cell membranes and modulate enzyme activity.
