    Cycloheximide A, EvoPure®

    $76.03 - $111.11

    Cycloheximide A, EvoPure® is a highly purified (≥99.0) form of cycloheximide A, the active compound in standard grade cycloheximide.

    Cycloheximide, isolated from Streptomyces griseus, is a protein synthesis inhibitor in eukaryotic cells and is commonly used to prevent fungal growth. It is soluble in DMSO.

    ApplicationCycloheximide is used in molecular biology for ribosome profiling / translational profiling to understand the complexity of translation initiation. Cycloheximide is used to study protein synthesis, expression and degradation, and determine the half-life of proteins.
    Mechanism of ActionCycloheximide binds to the ribosome and inhibits the eEF2-mediated translocation step in protein synthesis, thus blocking translational elongation.
    SpectrumCycloheximide is used for fungi and yeast, including fungi found in brewing test media. It has lower activity against bacteria.
    Microbiology ApplicationsCycloheximide chase followed by western blotting was used to analyze protein degradation in the model unicellular eukaryote, S. cerevisiae (buddiing yeast). Yeast cells are incubated in cycloheximide and cell aliquots are collected after specific time points. This allows visualization of the degradation kinetics of the steady state population of a variety of cellular proteins (Buchanan et al, 2016).

    Plant Biology ApplicationsCycloheximide is a commonly used lab reagent used in in vitro applications to inhibit fungal growth by targeting protein synthesis. In yeast, concentrations of 200 uM have fungicidal effects (Schneider-Poetsch et al, 2009). The compound can be used as a plant growth regulator to stimulate ethylene production in leaves and fruit.
    Eukaryotic Cell Culture ApplicationsCycloheximide is widely used in biomedical research to inhibit protein synthesis in eukaryotic cells studied in vitro. It inhibits the synthesis of proteins and macromolecules,and affects apoptosis in eukaryotes.
    Cancer ApplicationsPretreatment with cycloheximide followed by estrogen stimulation prevented the estrogen-induced changes in glucose metabolism in perfused breast cancer T47D clone 11 cells. This suggested that the estrogen stimulation requires synthesis of mRNA and protein (Neeman and Degani, 1989). In studying the “immune escape” of cancer cells, in human colorectal cancer cell line COLO 205 is normally resistant to TNF-alpha - a death inducing ligand. However, co-incubation TNF-alpha with cycloheximide caused time-dependent cell death. In fact, authors found that Cycloheximide sensitizes cells to TNF-alpha-induced apoptosis (Pajak et al, 2005).
