XI-006 is primarily utilized in research settings as a potent inhibitor targeting specific signaling pathways, particularly the Wnt/β-catenin pathway, which plays a critical role in cellular processes such as proliferation, differentiation, and survival. Its application is significant in studying diseases where this pathway is dysregulated, including various cancers, where it helps in understanding tumor growth and metastasis. Additionally, XI-006 is employed in developmental biology to explore the role of Wnt signaling in tissue regeneration and stem cell maintenance. Its inhibitory properties also make it a valuable tool in drug discovery, aiding in the development of therapeutic agents for conditions linked to abnormal Wnt signaling.
