trans-ISRIB

trans-ISRIB is an integrated stress response inhibitor. Potently reverses the effects of initiation factor 2α (eIF2α) phosphorylation (IC₅₀ = 5 nM). Enhances spatial and fear-associated learning in mice and enhances cognitive function. Mechanism of action involves activation of eiF2β. Suppresses ER stress-induced inflammatory gene expression. Potently attenuates amyloid β-induced neuronal cell death (12.5-25 nM) with no effect on amyloid β production. Reverses hippocampal-dependent cognitive deficits induced by traumatic brain injury in two different injury mouse models.
