Application

Nitisinone has been used:
  • to induce liver injury
  • to treat Ixodes scapularis tick cells to inhibit the activity of hydroxyphenylpyruvate dioxygenase
  • in supplemented water to block the accumulation of toxic metabolites in human hepatocyte engrafted mice
  • to study its effect on bacterial pyomelanin production

Biochem/physiol Actions

Nitisinone is a competitive and reversible inhibitor of 4-Hydroxyphenylpyruvate oxidase (dioxygenase).
Nitisinone is a competitive inhibitor that reversibly inhibits 4-Hydroxyphenylpyruvate oxidase (dioxygenase). Nitisinone is used in the treatment of hereditary tyrosinemia type 1, where it blocks the degradation of tyrosine into harmful substances.
