SGC-GAK-1 is primarily utilized in research settings as a potent and selective inhibitor of cyclin G-associated kinase (GAK). Its application is significant in the study of cellular processes, particularly in understanding the role of GAK in endocytosis, viral entry, and autophagy. Researchers employ SGC-GAK-1 to investigate its potential in modulating these pathways, which can provide insights into the development of therapeutic strategies for diseases such as cancer, neurodegenerative disorders, and viral infections. Additionally, it serves as a valuable tool in pharmacological studies to explore kinase-related mechanisms and their implications in various biological systems.
