3--Phenyl-N-(2,2,2-trichloro-1-((((4-chlorophenyl)amino)carbonothioyl)amino)ethyl)acrylamide Usage And Synthesis

Uses

Sal003 was used to study the role of eIF2α in Subtilase cytotoxin-induced apoptosis in HeLa cells.

Biological Activity

eukaryotic initiation factor 2 α-subunit (eif2α) plays a critical role in the regulation of protein synthesis. moreover, it also plays an important role in synaptic plasticity and long-term memory consolidation. sal003 is a selective inhibitor of eif2α dephosphorylation.

Biochem/physiol Actions

Sal003 inhibits the late long-term potentiation (L-LTP) and long-term memory formation in mammalian hippocampal slices. The effect of Sal003 on L-LTP is mediated by the transcription factor, ATF4.

in vitro

sal003 specifically prevents dephosphorylation of eif2α by blocking eif2α phosphatases. in sal003-treated cells polysomes dissociated and consistent with this β-actin mrna shifted to lighter fractions, reflecting the inhibition of general translation [1].

in vivo

intra-basolateral amygdala (bla) infusions of sal003 immediately after memory retrieval disrupted the reconsolidation of morphine- or cocaine-induced cpp, leading to a long-lasting suppression of drug-paired stimulus-induced craving. moreover, inhibition of eif2α dephosphorylation in the bla immediately after light/tone stimulus retrieval decreased subsequent cue-induced heroin-seeking behavior in the self-administration procedure. these results demonstrate that eif2α dephosphorylation in the bla mediates the memory reconsolidation of drug-paired stimuli [1].
