CAS 66-81-9: (-)-Cycloheximide

Cycloheximide (Naramycin A) is an antimitotic compound and an inhibitor of DNA and protein synthesis.

Cycloheximide is produced by the bacteria Streptomyces griseus. In eukaryotic organisms, it acts as an inhibitor of protein biosynthesis, interfering with protein elongation by binding to the E-site of ribosomes, after two elongation cycles. It has many in vitro applications, with the most popular being to determine a protein’s half-life. It is used as an antifungal in VTM. It does not appear to inhibit cell culture or viral replication at a concentration of 10ug/ml.

Cycloheximide, Antibiotic for Culture Media Use Only, is an antifungal agent derived from the Streptomyces griseus bacterium. Its primary mode of action involves the inhibition of eukaryotic protein synthesis by interfering with the translocation step on the 80S ribosome. This leads to rapid arrest of protein assembly, effectively limiting fungal and certain yeast growth in culture. Cycloheximide's unique properties make it invaluable in laboratory settings, specifically for the selective cultivation of bacteria in the presence of fungi. It is commonly used in research to prevent contamination in bacterial cultures, ensuring the precise study of bacterial phenotypes and genotypes. Its application extends to genetic studies, where it helps maintain the integrity of experimental conditions by controlling unwanted fungal proliferation. However, due to its broad inhibitory effects on eukaryotic cells, it is essential to handle cycloheximide with caution, ensuring its use is restricted to carefully controlled environments intended for scientific exploration.
