Protein synthesis and amnesia: studies with emetine and pactamycin.
    Pharmacology, biochemistry, and behavior, 1977, Volume: 6, Issue:1

    Two antibiotic inhibitors of protein synthesis, emetine and pactamycin, have been tested for their effects on cerebral and peripheral protein synthesis and amnesia. Peripherally administered emetine but not pactamycin inhibited cerebral protein synthesis, although this inhibition was lower than that observed with cycloheximide or anisomycin. Pactamycin had a lesser effect on adrenal protein synthesis than emetine. This was reflected in the ability of emetine but not pactamycin to block ACTH-induced corticosteroidogenesis. Anisomycin and cycloheximide caused amnesia in a passive avoidance task, whereas pactamycin and emetine did not. These results are inconsistent with the amnesia being due to inhibition of protein synthesis in a peripheral organ. They are also inconsistent with the amnesia being due to the suppression of an adrenocortical response as previously suggested. No obvious correlation between amnesia and the mechanism of protein synthesis was observed. The most parsimonious explanation is that inhibition of cerebral protein synthesis is necessary for amnesia.
