Used primarily in research settings to study cellular signaling pathways. It acts as a selective inhibitor of the TrkA receptor tyrosine kinase, which is involved in nerve growth factor signaling. This makes it valuable for investigating the role of TrkA in neuronal development, survival, and differentiation. Additionally, it is utilized in cancer research to explore the inhibition of TrkA in tumor growth and metastasis, particularly in cancers where TrkA signaling is dysregulated. Its application helps in understanding potential therapeutic targets for neurodegenerative diseases and certain types of cancer.
