Used primarily in research settings as a potent and selective inhibitor of fibroblast growth factor receptor 1 (FGFR1), this compound plays a key role in studying signaling pathways involved in cell proliferation, differentiation, and survival. It is widely applied in cancer research to investigate the inhibition of FGFR-driven tumor growth, particularly in cancers where FGFR signaling is dysregulated, such as certain types of breast cancer, multiple myeloma, and leukemia. Its ability to cross the blood-brain barrier also makes it valuable in studies targeting central nervous system tumors or neurological disorders involving aberrant FGFR activity. Additionally, it serves as a pharmacological tool to dissect the role of FGFR in developmental biology and tissue repair mechanisms.
