Cycloheximide

/ˌsaɪkloʊˈhɛksɪmaɪd/ noun

Definition

A powerful antibiotic compound that blocks protein production in eukaryotic cells, used in research and as a fungicide.

Etymology

From cyclohex- (six-membered ring) + imide (a type of chemical group). Discovered in 1945 from the bacterium Streptomyces, named for its ring structure plus the imide functional group.

Kelly Says

Cycloheximide is a favorite research tool because it specifically shuts down protein-making in animal and plant cells while leaving bacteria unharmed—it's like a molecular off-switch that lets scientists study exactly what happens when cells stop making proteins.
