Salubrinal is a drug which acts as a specific inhibitor of eIF2α phosphatase enzymes[1][2][3] 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,[4] resulting in activation of stress response pathways usually triggered by events such as oxidative stress or buildup of unfolded protein in the endoplasmic reticulum.[5] Salubrinal has putative therapeutic value due to its function,[1][3] but is as yet only used experimentally. Salubrinal is being studied at Indiana University for its potential to fight osteoporosis and accelerate bone healing.[6]
