Anisomycin

Anisomycin, also known as flagecidin, is an antibiotic produced by Streptomyces griseolus which inhibits eukaryotic protein synthesis. Partial inhibition of DNA synthesis occurs at anisomycin concentrations that effect 95% inhibition of protein synthesis. Anisomycin can activate stress-activated protein kinases, MAP kinase and other signal transduction pathways. Anisomycin is inactive against bacteria. Anisomycin interferes with protein and DNA synthesis by inhibiting peptidyl transferase or the 80S ribosome system.  >> Read More

Anisomycin (2-p-methoxyphenylmethyl-3-acetoxy-4-hydroxypyrrolidine) inhibits protein synthesis in HeLa cells, rabbit reticulocytes, Saccharomyces fragilis, and cell-free extracts prepared from these sources, but it is inactive against extracts of Escherichia coli. Partial inhibition of deoxyribonucleic acid synthesis in HeLa cells is observed at anisomycin concentrations which produce 95% inhibition of protein synthesis. These effects on protein and DNA synthesis are rapid in onset and reversible. Anisomycin acts on the transfer reaction subsequent to the formation of aminoacyl transfer ribonucleic acid. In the presence of anisomycin, nascent peptide remains attached to polyribosomes. No derivative of anisomycin that was tested showed more than 1% of the inhibitory activity of the parent compound.

Anisomycin is an immunosuppressant in low doses with possible application in treatment of some autoimmune diseases and in inhibiting transplantation rejection. Anisomycin suppresses malignant tumor cell growth and affects memory.
