salubrinal: prevents dephosphorylation of eIF2alpha; structure in first source [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

salubrinal : A member of the class of quinolines that is a mixed aminal resulting from the formal condensation oftrichloroacetaldehyde with the amide nitrogen of trans-cinnamamide and the primary amino group of 1-quinolin-8-ylthiourea. It is a selective inhibitor of cellular complexes that dephosphorylate eukaryotic translation initiation factor 2 subunit alpha (eIF2alpha).
