Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Shows activity in modulating cellular signaling pathways involved in tumor growth and inflammation. Also employed in research settings to study apoptosis and cell cycle regulation. Its structure allows for strong binding to specific enzyme active sites, making it valuable in designing targeted therapies. Additionally, it serves as a building block in the preparation of fluorescent probes for biochemical imaging due to its conjugated aromatic system.
