Cycloheximide,66-81-9,IC-0200336
Cycloheximide is an antibiotic that inhibits protein synthesis at the translation level, acting exclusively on cytoplasmic (80s) ribosomes of eukaryotes. Cycloheximide affected all the energy-dependent stages in the protein-synthesizing process. However, the initiation seems the most sensitive. Cycloheximide also affects respiration, ion uptake, amino acid biosynthesis, and DNA and RNA synthesis, effects that are probably secondary to its effect on protein synthesis.[1] In vitro study indicated that Cycloheximide at 1 μM inhibited [3H]leucine incorporation into both cellular and secreted proteins by at least 86%, without having deleterious effects on membrane integrity as indicated by trypan blue uptake and lactate dehydrogenase release. Larger size class polysomes (7+) were increased by Cycloheximide treatment and remained increased during recovery. [2] In vivo analysis indicated that Cycloheximide produced initial hyperactivity. This initial hyperactivity was apparent within 3 minutes after injection of the Cycloheximide. Cycloheximide affects activity by acting on the brain, and this is unrelated to its inhibition of protein synthesis. In addition, Cycloheximide’s effects on activity did not appear to be responsible for its amnesic action. However, Cycloheximide might have some other property, unrelated to inhibition of cerebral protein synthesis, that is responsible for its amnesic effect.[3]
