Application

Salubrinal has been used to study the effect of stress-protective genes and pathways on organism development and lifespan. It has also been used to study the therapeutic potential of salubrinal in methamphetamine induced blood–brain barrier disruption.

Biochem/physiol Actions

Salubrinal is a selective Inhibitor of eIF2α (eukaryotic translation initiation factor 2 α-subunit) dephosphorylation, inhibiting global protein translation. Salubrinal is a specific inhibitor of ER Stress induced apoptosis.
Salubrinal maintains protein phosphorylation in order to offer protection against from the adverse effects of endoplasmic reticulum stress. Salubrinal prevents collagenase-mediated articular cartilage damage promoting downregulation of matrix metalloproteinase 13.
