OGT 2115 is primarily utilized in biochemical research, particularly in the study of glycosylation processes. It serves as a potent and selective inhibitor of O-GlcNAcase, an enzyme responsible for the removal of O-GlcNAc modifications from proteins. By inhibiting this enzyme, OGT 2115 allows researchers to investigate the role of O-GlcNAc in cellular signaling, protein function, and overall cellular regulation. This compound is especially valuable in studies related to metabolic regulation, neurodegenerative diseases, and cancer, where O-GlcNAc dynamics play a critical role. Its application helps in understanding the biochemical pathways influenced by O-GlcNAc modifications, providing insights into potential therapeutic targets.
