Application

  • Bis(cyclohexanone)oxaldihydrazone (Cuprizone) has been used in mice to study the effect of NG2 (neural/glial antigen 2) proteoglycan on toxic-induced demyelination.
  • It has been used to induce demyelination in mice.
  • It has been used to study cuprizone-induced demyelination and remyelination in the corpus callosum of mice.

Biochem/physiol Actions

Bis(cyclohexanone)oxaldihydrazone (Cuprizone) is a copper chelator. It results in oligodendroglial cell death, thereby leading to demyelination, astrogliosis and microglia activation. Cuprizone is widely used to study mitochondrial dysfunction-associated primary demyelination and remyelination in the corpus callosum.
