Cycloheximide, also known as Actidione, is a glutarimide antibiotic commonly derived from the bacterium Streptomyces griseus. It acts as a potent inhibitor of protein biosynthesis in eukaryotic cells by disrupting the translocation step during translation, effectively blocking translational elongation. In microbiology, it plays a crucial role as a selection agent for resistant strains of yeast and fungi, proving invaluable in controlled experimental environments.
