Description and Uses
Cycloheximide is a glutarimide-type antibiotic produced by Streptomyces griseus. Colorless crystals, C15H23NO4 (281.4), melting point: 115.5–117 ?C, weak acidic substance (pKa 11.2), Soluble in chloroform, isopropanol and methanol; water > 21 g/L (2 ?C). Stable in pH 3–5, but rapidly destroyed in alkaline solutions.
Cycloheximide is an antibiotic substance isolated from the beers of streptomycin-producing strains of Streptomyces griseus. Cycloheximide is used as fungicide.
