Anisomycin, also known as flagecidin is an antibiotic produced by Streptomyces griseolus which inhibits protein synthesis. Partial inhibition of DNA synthesis occurs at anisomycin concentrations that effect 95% inhibition of protein synthesis.[2] Anisomycin can activate stress-activated protein kinases, MAP kinase and other signal transduction pathways.

Anisomycin is inactive against bacteria.
