ISRIB (integrated stress response inhibitor) has been used as an inhibitor of integrated stress response.
Biochem/physiol Actions
ISRIB (integrated stress response inhibitor) as a drug, imparts resistance to the cells against the downstream effects of eukaryotic initiation factor 2 (eIF2)? phosphorylation such as activating transcription factor 4 (ATF4) and eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1) induction.
ISRIB is a blood- brain barrier penetrant, potent and selective inhibitor of integrated stress response (ISR) that impairs adaptation to ER stress. ISRIB is a potent inhibitor of PERK signaling, which potently reverses the effects of eIF2a phosphorylation and restores the cells translation capacity. ISRIB enhances cognitive memory in rodents.
