CCT020312 is primarily used in research settings to study cellular stress responses and signaling pathways. It is known for its role as a selective activator of the unfolded protein response (UPR) pathway, specifically targeting the PERK branch. Researchers utilize this compound to investigate the mechanisms of ER stress and its implications in diseases such as cancer, neurodegenerative disorders, and diabetes. By modulating the UPR, CCT020312 helps in understanding how cells cope with protein misfolding and ER dysfunction. It is also employed in preclinical studies to explore potential therapeutic strategies for conditions linked to ER stress.
