Beschreibung

Application

L-Dihydroorotic acid has been used as a substrate in dihydroorotate dehydrogenase (DHODH) assay.[1][2][3]

Biochem/physiol Actions

L-Dihydroorotic acid (DHO) serves as a substrate for dihydroorotate dehydrogenase (DHODH), an enzyme in the de novo synthesis of pyrimidine. Inhibition of DHOH by its inhibitors causes a large accumulation of upstream metabolite DHO and a reduction in the uridine levels. Therefore, DHO and uridine can be used as biomarkers for pyrimidine synthesis for the clinical development of DHOH inhibitors.[4]
