JW55 is primarily utilized in biomedical research, particularly in the study of cancer and neurodegenerative diseases. It functions as a selective inhibitor of the Wnt/β-catenin signaling pathway, which plays a critical role in cell proliferation and differentiation. By targeting this pathway, JW55 helps researchers investigate its involvement in tumor growth and progression, offering potential insights for developing cancer therapies. Additionally, its application extends to studying conditions like Alzheimer's disease, where Wnt signaling dysregulation is implicated. JW55 serves as a valuable tool for understanding disease mechanisms and exploring therapeutic interventions.
