GSK9311 is primarily utilized in biochemical research as a potent and selective inhibitor of the enzyme glycogen synthase kinase-3 (GSK-3). Its application is significant in studying cellular signaling pathways, particularly those involved in glucose metabolism, cell proliferation, and apoptosis. Researchers employ GSK9311 to investigate its effects on diseases such as diabetes, neurodegenerative disorders, and cancer, where GSK-3 plays a critical role. Additionally, it is used in preclinical studies to explore potential therapeutic interventions targeting GSK-3-related mechanisms. Its specificity makes it a valuable tool for understanding the complex regulatory functions of GSK-3 in various biological processes.
