Deacetylanisomycin (CAS 27958-06-1)

Deacetylanisomycin, identified by the CAS number 27958-06-1, is a derivative of anisomycin, a well-known antibiotic that functions as a protein synthesis inhibitor. This compound differs from anisomycin by the removal of an acetyl group, a modification that impacts its biological activity and interaction with cellular targets. Deacetylanisomycin operates by binding to the 60S ribosomal subunit, specifically influencing the peptidyl transferase center within the large ribosomal subunit. This binding disrupts the normal function of the ribosome, leading to the inhibition of peptide bond formation, which is a crucial step in the translation process of protein synthesis. Consequently, this interference effectively halts the elongation phase of protein synthesis, thereby inhibiting overall protein production in cells. In research contexts, deacetylanisomycin is utilized primarily to study the mechanisms of protein synthesis at the molecular level and to explore the cellular responses to inhibited translation such as stress response pathways, including the MAPK signaling pathway. Researchers also employ deacetylanisomycin to investigate the structural and functional aspects of ribosomal components, providing insights into how modifications in ribosome-targeting antibiotics affect their interaction with ribosomes and their subsequent biological activities. This research is crucial for understanding the fundamental processes that control cell growth and response to environmental stresses.
