General description

5,5-Diphenylhydantoin sodium salt is a derivative of phenytoin. 5,5-Diphenylhydantoin is used for treating epilepsy and has antiepileptic activity. It functions by blocking the sodium channels and modulates excitation of neurons. However, the side effects include hypertrichosis and overgrowth of gum tissue around the teeth. It promotes proliferation of the neural stem cells by modulating growth factors. Diphenylhydantoin is toxic and induces apoptosis in cultured cerebellar granule neurons.

Application

5,5-Diphenylhydantoin sodium salt has been used:
  • in the cream preparation for treating burn wounds
  • in seizure behavior testing as an anticonvulsant in Drosophila
  • in in vivo embryo toxicity test in mouse embryonic stem cells

Biochem/physiol Actions

Reduces incidence of grand mal seizures; appears to stabilize excitable membranes perhaps through effects on Na+, K+, and Ca2+ channels.
