ID-8 is primarily utilized in biological and medical research, particularly in the study of cellular processes and signaling pathways. It is known for its role as an inhibitor of the enzyme glycogen synthase kinase-3 (GSK-3), which is involved in various cellular functions, including metabolism, cell division, and apoptosis. By inhibiting GSK-3, ID-8 helps researchers understand its impact on diseases such as cancer, diabetes, and neurodegenerative disorders. Additionally, ID-8 is used in stem cell research to enhance the self-renewal and pluripotency of stem cells, making it a valuable tool in regenerative medicine and tissue engineering studies. Its application in these fields contributes to advancements in therapeutic strategies and drug development.
