4-Hydroxyphenylpyruvate dioxygenase

4-Hydroxyphenylpyruvate dioxygenase (HPPD) is an Fe(II)-dependent, non-heme oxygenase that catalyzes the conversion of 4-hydroxyphenylpyruvate to homogentisate. HPPD catalyzes the second step in the pathway for the catabolism of tyrosine, that is common to essentially all aerobic forms of life. In plants this pathway has an anabolic branch from homogentisate that forms essential isoprenoid redox cofactors such as plastoquinone and tocopherol.he transformation catalyzed by HPPD has both agricultural and therapeutic significance

    Nitisinone is an orally active, competitive and reversible 4-hydroxyphenylpyruvate dioxygenase (4-HPPD) inhibitor with an IC50 of 173 nM. Nitisinone promotes tyrosine accumulation in a dose-dependent manner. nitisinone can be used in studies of hereditary tyrosinemia type 1 (HT-1) (a rare genetic disorder) and albinism.
  • HY-118742
    Benzobicyclon is a 4-HPPD inhibitor and herbicide that reacts with water to form a hydrolysate of the active herbicide benzobicycline, causing bleaching and death of weeds. Benzobicyclon is effective against grass, sedge and broadleaf weeds. Benzobicyclon effectively targets sulfonylurea herbicide-resistant biotypes as well as wild-type weeds.
