Nitisinone 生物活性

描述 Nitisinone is an orally active, competitive, and reversible inhibitor of 4-hydroxyphenylpyruvate dioxygenase (4-HPPD) with an IC50 of 173 nM. It increases tyrosine levels in a dose-dependent manner and is utilized in research related to hereditary tyrosinemia type 1 (HT-1), a rare genetic disorder, and albinism[1].[2].[3].[4].
体内研究

Administered orally at doses of 5 and 10 mg/kg, five days a week for six weeks, Nitisinone consistently inhibits 4-HPPD in rat liver in both a dose- and time-dependent manner[2].

Nitisinone, at a dose of 4 mg/kg administered orally once daily with a day's interval for a month, increases tyrosine levels in both OCA-1A and OCA-1B models[3].

The same dosing regimen of Nitisinone (4 mg/kg; orally; once daily; one day interval for one month) also enhances coat and iris pigmentation and increases melanin content in the melanosomes of ocular tissues in a mouse model of OCA-1B[3].

体外研究

Nitisinone (ranging from 0.01 to 10 μM over 72 hours) enhances tyrosine accumulation in a dose-responsive manner[1].
