Salubrinal is a drug which acts as a specific inhibitor of eIF2α phosphatase enzymes^[3][4][5] and is primarily used experimentally, to study stress responses in eukaryotic cells associated with the action of eIF2. Salubrinal indirectly inhibits eIF2 as a result of reduced dephosphorylation of its α-subunit,^[6] resulting in activation of stress response pathways usually triggered by events such as oxidative stress or buildup of unfolded protein in the endoplasmic reticulum.^[7] Salubrinal has putative therapeutic value due to its function,^[3][5] but is as yet only used experimentally. Salubrinal is being studied at Indiana University for its potential to fight osteoporosis and accelerate bone healing.^[8]
