Blasticidin S HCl is a nucleoside antibiotic isolated from Streptomyces griseochromogenes[1]. Blasticidin S HCl specifically inhibits protein synthesis in prokaryotic or eukaryotic cells by interfering with ribosome binding peptides. The inhibitory effect of Blasticidin S HCl on translation termination is conserved in eukaryotes and bacteria[2-4].

Blasticidin S HCl treatment stabilizes the premature stop codon-mutated mRNA in HeLa cells, Blasticidin S HCl inhibits nonsense-mediated mRNA decay and, at subinhibitory concentrations, modulates translation dynamics at premature termination codons leading to enhanced protein production[5]. The presence of Blasticidin S HCl protects DNA from Cu(II) -induced damage[6].
