Inz-1 is primarily utilized in the field of biomedical research, particularly in the study of cellular processes and signaling pathways. It serves as a selective inhibitor of the enzyme tankyrase, which plays a crucial role in regulating various cellular functions, including telomere maintenance and Wnt/β-catenin signaling. Researchers employ Inz-1 to investigate the effects of tankyrase inhibition on cancer cell proliferation and to explore its potential as a therapeutic target for cancer treatment. Additionally, it is used in studies aimed at understanding the molecular mechanisms underlying tissue regeneration and stem cell biology.
