anisomycin

:  a white crystalline antibiotic C₁₄H₁₉NO₄ obtained from a soil streptomycete (Streptomyces griseolus) that inhibits protein synthesis, is effective against certain pathogenic protozoans and fungi, and is used especially in laboratory research The application of various inhibitors of protein synthesis such as anisomycin and cycloheximide disrupts long-term memory formation, while it leaves short-term memory almost intact. — Satoru Otani and Yehezkel Ben-Ari, International Review of Neurobiology, Volume 35, 1993
