    Description: Salubrinal is a novel, potent, cell-permeable and selective inhibitor of eIF2α (eukaryotic translation initiation factor 2 subunit α) dephosphorylation with potential anticancer activity. It inhibits ER stress-mediated apoptosis with EC50 of ~15 μM in cell-free assays. The eukaryotic translation initiation factor 2 subunit α (eIF2α) is crucial in protein synthesis. eIF2α phosphorylation played an important role in protecting cells from apoptosis. Salubrinal selectively suppresses the phosphatase complexes that dephosphorylate eIF-2α. Salubrinal inhibits eIF2α dephosphorylation by inhibiting the PP1/GADD34 complex. Salubrinal inhibits HSV replication with IC50 of ~ 3μM by inhibiting eIF2α dephosphorylation.

    In VitroSalubrinal is a selective inhibitor of cellular complexes that dephosphorylate eukaryotic translation initiation factor 2 subunit α (eIF2α). Salubrinal inhibited ER stress-mediated apoptosis induced by the protein glycosylation inhibitor tunicamycin (Tm) in a dose-dependent manner, with a median effective concentration (EC50) ∼ 15 μM. Salubrinal also suppressed Tm-induced DNA fragmentation the processing of caspase-7, a caspase activated by ER stress.
    In VivoSalubrinal inhibits HSV replication in a mouse cornea infection model. Compared to vehicle control, topical Salubrinal treatment significantly reduced the viral titer recovered from eye swabs of infected animals. I.C.V. administration of Salubrinal significantly modified the homeostatic sleep response.
